Description
Technical Field
The invention relates to the technical field of manufacturing of textile machinery equipment, in particular to a weft laying mechanism and a weft laying machine comprising the same.
Background
The carbon fiber is a novel material with the carbon content of more than 95 percent and has the characteristics of high strength and high modulus. The carbon fiber is formed by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and the microcrystalline graphite material obtained by carbonization and graphitization treatment not only has the intrinsic characteristics of a carbon material, but also has the soft processability of textile fiber.
The fiber cloth is woven by carbon fibers, and the production process is as follows: the method comprises the steps of flattening a carbon fiber bundle into flat-laid monofilament carbon fibers by a yarn spreading machine, then bonding and forming into a fiber cloth strip by glue, then performing weft laying operation on the fiber cloth strip by a weft laying machine, and then performing warp and weft cross weaving operation on the weft-laid fiber cloth strip by a warp knitting machine to finally form the fiber cloth.
In the actual working process of the weft laying machine, the fiber cloth strips to be cut are pulled by the weft pulling mechanism to sequentially pass through the fiber cloth strip cutting mechanism, the left feeding mechanism and the right feeding mechanism. The fiber cloth strip cutting mechanism cuts off the tensioned fiber cloth strips, then the left feeding mechanism and the right feeding mechanism synchronously act to carry out weft laying operation on the tensioned fiber cloth strips, at the moment, two ends of the fiber cloth strips are respectively pressed and fixed into the left weft laying mechanism and the right weft laying mechanism, and the left weft laying mechanism and the right weft laying mechanism carry out synchronous displacement motion to send the weft laying fiber cloth strips into the warp knitting machine to carry out warp and weft knitting operation.
According to the common design knowledge, the left weft laying mechanism and the right weft laying mechanism can adopt various design structures to complete the plane weft laying operation aiming at the fiber cloth strips in a cooperative action manner. The left weft laying mechanism and the right weft laying mechanism have similar design structures and are different only in arrangement direction. Taking a left weft laying mechanism as an example, in the prior art, the weft laying mechanism mainly comprises a flat base plate, a needle mounting assembly, a pressure bearing assembly, a pressing assembly, a driving unit and the like. Wherein, the horizontal base plate is borne by a frame of the weft laying machine and is arranged right below the left feeding mechanism. The bearing assembly is composed of a plurality of L-shaped bearing pieces which are arranged side by side along the front-back direction and are detachably fixed on the top wall of the flat base plate. The pressing assembly is composed of a plurality of U-shaped pressing pieces which are arranged side by side along the front and back direction and can freely perform sliding motion along the left and right direction so as to realize the design aim of being contacted with the L-shaped bearing piece. The needle mounting assembly performs displacement movement synchronously along the front and rear directions following the bearing assembly and is composed of a plurality of needle mounting pieces detachably fixed on the right side wall of the L-shaped bearing piece. The driving unit is composed of a plurality of groups of driving subunits which are arranged side by side along the front-back direction. Each driving subunit is used for respectively driving the corresponding group of U-shaped pressing pieces to perform displacement movement towards/away from the corresponding group of L-shaped pressure-bearing pieces so as to realize/release the compression of the left end of the fiber cloth strip section. With the advance of the weft laying process, each group of driving subunits are sequentially started due to different time of receiving the control signals, so that the design goal of sectional and batch-wise compression of the fiber cloth strip section is realized. As can be seen from the above description, the existing left weft laying mechanism has a very complicated design structure, and specifically, needs to arrange a plurality of groups of driving subunits side by side along the front-back direction of the weft laying machine, so that, on one hand, more capital needs to be invested to purchase the plurality of groups of driving subunits, which leads to the increase of the overall manufacturing cost of the weft laying machine; on the other hand, a plurality of groups of driving subunits occupy larger design space, which is not only unfavorable for the execution of space layout design work, but also can cause the extension of the overall installation time of the weft laying machine; on the other hand, the design weight of the weft laying mechanism is inevitably increased greatly, and the implementation of the weight-reducing design target of the weft laying machine is further not facilitated. Thus, a skilled person is urgently needed to solve the above problems.
Disclosure of Invention
Therefore, in view of the above-mentioned problems and drawbacks, the present invention provides a weft insertion mechanism that is capable of collecting relevant information, evaluating and considering the relevant information, and performing various experiments and modifications by a skilled person engaged in the industry.
In order to solve the technical problem, the invention relates to a weft laying mechanism which is used for carrying out laying operation on fiber cloth strips and sending the laid limiting cloth strips into a warp knitting mechanism. The weft laying mechanism comprises a supporting beam, an external U-shaped frame, an internal U-shaped frame, a needle mounting assembly, a first guide assembly, a first driving part, a second driving part and a third driving part. The external U-shaped frame is supported by a support beam, reciprocates in the front-rear direction under the action of the driving force of the first driving unit, and is composed of N external U-shaped members arranged side by side in the front-rear direction. The needle mounting assembly synchronously executes displacement motion along the front-back direction along with the external U-shaped frame, and is composed of N needle mounting pieces detachably fixed on the outer side wall of the external U-shaped piece. The built-in U-shaped frame is placed in an inner cavity of the external U-shaped frame, performs displacement motion synchronously along the front-back direction along with the external U-shaped frame, and is composed of N built-in U-shaped pieces which are arranged side by side along the front-back direction. The first guide assembly is composed of N guide subassemblies which are linearly arranged along the front-back direction and enable the built-in U-shaped frames corresponding to the N guide subassemblies to directionally perform sliding movement along the left-right direction. The external U-shaped element and the internal U-shaped element cooperate to achieve/release the compression of the fiber cloth strip extending out through the corresponding needle mounting element. The second driving part is arranged on one side of the supporting beam and is used for sequentially driving the built-in U-shaped pieces in each section to perform displacement motion along the left-right direction so as to release the pressing of the corresponding external U-shaped pieces. The third driving part is composed of N elastic top-applying subunits which are linearly arranged along the front-back direction and are assembled between the external U-shaped piece and the internal U-shaped piece in a one-to-one correspondence mode. Each internal U-shaped part automatically resets under the action of elastic pushing force of the corresponding elastic jacking subunit, so that the external U-shaped part corresponding to the internal U-shaped part is pressed.
As a further improvement of the technical scheme of the invention, the elastic top applying subunit comprises a cylindrical spring. The columnar spring is arranged in the inner cavity of the external U-shaped frame and is always elastically pressed between the internal U-shaped piece and the external U-shaped piece.
As a further improvement of the technical scheme of the invention, the elastic top applying subunit also comprises a left limiting column and a right limiting column. The left limiting column is used for sleeving the left end part of the columnar spring and is embedded in the left side wall of the external U-shaped part. The right limiting column is used for sleeving the right end part of the columnar spring and is embedded on the left side wall of the built-in U-shaped piece.
As a further improvement of the technical scheme of the invention, the guide sub-assembly is a pilot screw. The guide screw is screwed on the top wall of the external U-shaped piece, and correspondingly, a waist-shaped guide notch which is matched with the guide screw and extends along the left-right direction is formed in the internal U-shaped piece.
As a further improvement of the technical scheme of the invention, the weft laying mechanism also comprises an elastic cushion component. The resilient pad assembly is comprised of an inner resilient pad subassembly and an outer resilient pad subassembly that cooperate to perform a resilient compression operation on the fabric. The built-in elastomeric pad subassembly is comprised of N built-in elastomeric pad strips removably secured to the right side wall of the built-in U-shaped member. The external elastic liner subassembly is composed of N external elastic liner strips which are detachably fixed on the right side wall of the external U-shaped piece and are opposite to the internal elastic liner strips.
As a further improvement of the technical scheme of the invention, the needle installing piece consists of N installing seats and M carding wires. The mounting seat is detachably fixed on the right side wall of the external U-shaped piece through screws, and M insertion blind holes for the carding wires to perform insertion operation extend downwards from the top wall of the mounting seat.
As a further improvement of the technical solution of the present invention, the first driving portion includes a first rotating electrical machine, a chain transmission mechanism and a dragging assembly. The dragging assembly is composed of N dragging pieces which are matched with the external U-shaped pieces and used for independently dragging the external U-shaped pieces one by one. The first rotating motor is hidden in the cavity of the support beam and applies dragging force to the dragging assembly through the chain transmission mechanism.
As a further improvement of the technical solution of the present invention, the first driving portion further includes a second guiding component. The second pilot assembly comprises N vertical guide bearings and N horizontal guide bearings which are detachably fixed on the towing piece. The vertical guide bearings cooperate to eliminate play in the up and down direction of travel of the tow assembly displacement during travel. The horizontal guide bearings cooperate to eliminate play in the left-right direction of travel of the tow assembly displacement during travel. A vertical guide edge matched with the horizontal guide bearings and always pressed by the horizontal guide bearings extends upwards from the top wall of the support beam. A horizontal guide edge matched with the vertical guide bearings and always pressed by the vertical guide bearings extends from the support beam.
As a further improvement of the technical scheme of the invention, the second driving part comprises a supporting seat, a bearing substrate, a gear rack driving mechanism, a second speed reducing motor, an ejector and a linear driving unit. The supporting seat is borne by the framework of the weft laying machine and is arranged on one side of the supporting beam. The bearing substrate is used for installing and fixing the linear driving unit and performs displacement motion in a reciprocating manner along the front-back direction under the synergistic action of the gear rack driving mechanism and the second speed reduction motor. The ejector performs a displacement motion reciprocally in the left-right direction under the action of the linear drive unit to additionally drag the plurality of pieces of the built-in U-shaped pieces at the same time.
As a further improvement of the technical scheme of the invention, the gear rack driving mechanism is composed of a gear and a rack. The rack is arranged under the bearing substrate and detachably fixed on the top wall of the supporting seat. The second speed reduction motor is detachably fixed on the bearing substrate. The gear engaged with the rack is directly driven by the second reduction motor.
As a further improvement of the technical scheme of the invention, the linear driving unit comprises a cylinder, a hydraulic cylinder or a linear motor, wherein Q pieces are borne by the bearing substrate and cooperate to drive the ejector.
As a further improvement of the technical solution of the present invention, the second driving portion further includes a third guiding component. The third guiding assembly is composed of a left third guiding subassembly and a right third guiding subassembly which cooperate to guide the moving direction of the bearing substrate. The left third guide subassembly comprises a left slide rail and a left slide block. The right third guide subassembly comprises a right slide rail and a right slide block. The left slide rail and the right slide rail are detachably fixed on the top wall of the supporting seat and are arranged in parallel. The left slide block matched with the left slide rail and the right slide block matched with the right slide rail are detachably fixed on the bottom wall of the bearing substrate.
Taking the left weft laying mechanism as an example, in the actual working process of the weft laying machine, in the initial state, the grouped internal U-shaped pieces are kept in a close contact state with the grouped external U-shaped pieces opposite to the grouped internal U-shaped pieces due to the action of the elastic pushing force of the third driving part. After a certain batch of fiber cloth strip sections are fed into a certain section of needle assembly under the action of the left feeding mechanism, the second driving part opposite to the certain batch of fiber cloth strip sections is started, the group of internal U-shaped elements perform left movement until the group of internal U-shaped elements are separated from the group of external U-shaped elements under the action of dragging force, then the left feeding mechanism continues to perform pressing action to enable the left ends of the fiber cloth strip sections to freely fall into gaps formed between the group of internal U-shaped elements and the group of external U-shaped elements, then the second driving part loses function to release the dragging action of the internal U-shaped elements, and then the third driving part is started, the group of internal U-shaped elements perform right movement until the group of internal U-shaped elements are in abutting contact with the group of external U-shaped elements under the action of elastic pushing force, and at the moment, the left ends of the batch of fiber cloth strip sections are reliably pressed. And circulating the action processes for multiple times until the pressing operation of the whole batch of fiber cloth strips is completed. It should be noted that, when the feeding and pressing operations of the next batch of fiber strip sections are required to be performed, the second driving part needs to be adaptively shifted in the front-rear direction to keep synchronization with the feeding process of the fiber strip sections.
Through adopting above-mentioned technical scheme to set up, can realize the effective drive to built-in U-shaped frame with the help of single power supply (be the second drive division). During the weft laying process, the second driving part adaptively changes the output direction of the ejection force according to the difference of the actual weft laying position so as to sequentially drive the built-in U-shaped pieces in each section in batches. Therefore, the method has the following advantages in practical application:
1) the design structure of the weft laying mechanism is greatly simplified, the manufacturing and implementation difficulty is effectively reduced, and the purchasing cost is greatly reduced;
2) the design space required by the second driving part is relatively small, which is not only beneficial to the execution of space layout design work, but also can cause the reduction of the overall installation time of the weft laying machine;
3) the design weight of the weft laying mechanism is effectively reduced, and the implementation of a weight reduction design target of the weft laying machine is facilitated.
In addition, the invention also discloses a weft laying machine which comprises a fiber cloth strip feeding system, a left feeding mechanism, a right feeding mechanism, a fiber cloth strip cutting mechanism, a weft pulling mechanism and the two weft laying mechanisms which are oppositely arranged along the left and right directions. The fiber cloth strip feeding system is used for flattening the fiber cloth roll and feeding the fiber cloth roll to the fiber cloth strip cutting mechanism. The left feeding mechanism and the right feeding mechanism are oppositely arranged along the left and right directions, the motion process is kept synchronous, and the left feeding mechanism and the right feeding mechanism are matched with the fiber cloth strip cutting mechanism to be applied so as to receive the fiber cloth strips cut off by the fiber cloth strip cutting mechanism and press the left end part and the right end part of the fiber cloth strip section into the two weft laying mechanisms in a one-to-one correspondence manner. The weft pulling mechanism is matched with the fiber cloth strip feeding system for application so as to pull the fiber cloth strips to be cut to pass through the fiber cloth strip cutting mechanism, the left feeding mechanism and the right feeding mechanism in sequence.

The left feeding mechanism 2 and the right feeding mechanism 3 are oppositely arranged along the left-right direction, the motion process is kept synchronous, and the left feeding mechanism and the right feeding mechanism are matched with the fiber cloth strip cutting mechanism 4 to receive the fiber cloth strips cut by the fiber cloth strip cutting mechanism 4, and the left end part and the right end part of the fiber cloth strip section are pressed into two weft laying mechanisms oppositely arranged along the left-right direction in a one-to-one correspondence manner (for the convenience of subsequent explanation, the left weft laying mechanism 6 and the right weft laying mechanism are respectively named as the left weft laying mechanism and the right weft laying mechanism). The weft pulling mechanism 5 is used in conjunction with the fiber cloth strip feeding system 1, and is used for pulling the fiber cloth strip released by the fiber cloth strip feeding system 1 and guiding the fiber cloth strip to the right feeding mechanism 3. In the actual working process of the weft laying machine, the fiber cloth strips to be cut are pulled by the weft pulling mechanism 5 to sequentially pass through the fiber cloth strip cutting mechanism 4, the left feeding mechanism 2 and the right feeding mechanism 3. The fiber cloth strip cutting mechanism 4 cuts off the tensioned fiber cloth strip, then the left feeding mechanism 2 and the right feeding mechanism 3 synchronously act (execute displacement motion along the front-back direction) to execute weft laying operation on the severed fiber cloth strip, at the moment, two ends of the fiber cloth strip are respectively pressed in and fixed to the left weft laying mechanism 6 and the right weft laying mechanism, the left weft laying mechanism 6 and the right weft laying mechanism execute synchronous displacement motion to send the weft laying fiber cloth strip into a warp knitting machine to execute warp and weft knitting operation, and finally fiber cloth is formed.
In practical application, the two weft laying mechanisms cooperate with each other to complete the plane weft laying operation aiming at the fiber cloth strips. The two opposite weft laying mechanisms have the same design and differ only in the arrangement orientation. In the present embodiment, the left weft insertion and laying mechanism 6 is described as an example, and mainly includes a support beam 61, an outer U-shaped frame 62, an inner U-shaped frame 63, a needle installing unit 64, a first guide unit 65, a first driving unit 66, a second driving unit 67, a third driving unit 68, and the like, as shown in fig. 2, 3, 4, and 5. The external U-shaped frame 62 is supported by the support beam 61, reciprocates in the front-rear direction by the driving force of the first driving unit 66, and is formed of N external U-shaped members 621 arranged side by side in the front-rear direction. The needle mounting assembly 64 performs a displacement movement synchronously along the front-rear direction following the outer U-shaped frame 62, and is composed of N needle mounting members 641 detachably fixed to the outer side wall of the outer U-shaped member 621. The internal U-shaped frame 63 is always located in the inner cavity of the external U-shaped frame 62, performs displacement movement synchronously in the front-rear direction following the external U-shaped frame 62, and is composed of N internal U-shaped members 631 arranged side by side in the front-rear direction. The first guide assembly 65 is constituted by N guide subassemblies 651 linearly arranged in the front-rear direction so that the built-in U-shaped frame 63 corresponding thereto performs a sliding motion in a left-right direction orientation. The outer U-shaped element 621 and the inner U-shaped element 631 cooperate to effect/release the compression of the strip of fibre cloth extending out through the corresponding needle mounting element 641. The second driving portion 67 is disposed on one side of the support beam 61 and is used to sequentially drive the inner U-shaped members 631 in the respective stages to perform a displacement movement in the left-right direction to release the pressing against the corresponding outer U-shaped members 621. An effective drive of the built-in U-shaped frame 63 is achieved by means of the single second drive portion 67. In the weft laying process, the second driving part 67 adaptively changes the output orientation of the ejection force according to the difference of the actual weft laying position to sequentially drive the built-in U-shaped members 631 in each section in batches. The third driving unit 68 is composed of N elastic top sub units 681 linearly arranged in the front-rear direction and assembled between the external U-shaped member and the internal U-shaped member in one-to-one correspondence. Each built-in U-shaped part 631 automatically resets under the elastic pushing force of the corresponding elastic jacking sub-unit 681, so as to press against the corresponding external U-shaped part 621.
The working principle of the left weft laying mechanism is as follows: in the initial state, the set of inner U-shaped members 631 are held in close contact with the set of outer U-shaped members 621 opposite thereto by the elastic urging force of the third driving portion 68. After a certain batch of fiber cloth strip is fed to a certain needle assembly 64 under the action of the left feeding mechanism 2, the second driving portion 67 is activated and the group of inner U-shaped members 631 perform a left movement under the dragging force until they are disengaged from the group of outer U-shaped members 621, then, the left feeding mechanism 2 continues to perform the pressing action to make the left end of the fiber cloth strip section freely hang down in the gap formed between the group of inner U-shaped members 631 and the group of outer U-shaped members 621, subsequently, the second driving portion 67 is disabled to release the dragging action of the built-in U-shaped piece 631, then, the third driving part 68 is started, and the group of inner U-shaped elements 631 perform a right movement under the action of the elastic pushing force until the group of inner U-shaped elements 621 contact with each other, at which point, the left end of the batch of fiber cloth strip segments is reliably pressed. And circulating the action processes for multiple times until the pressing operation of the whole batch of fiber cloth strips is completed. It should be noted that, when the feeding and pressing operations of the next batch of fiber cloth strip sections are to be performed, the second driving portion 67 needs to be adaptively shifted in the front-rear direction to keep synchronization with the feeding process of the fiber cloth strip sections.
Through adopting above-mentioned technical scheme to set up, the left side of above-mentioned project organization has made the following beneficial effect in several respects at least in practical application:
1) the left weft laying mechanism 6 has a simple design structure, thereby not only effectively reducing the difficulty of manufacturing and implementing, but also greatly reducing the purchase cost of a matching part;
2) the design space required by the second driving part 67 is relatively small, which is not only beneficial to the execution of space layout design work, but also can lead to the reduction of the assembly time of the left weft laying mechanism 6 and the overall installation time of the weft laying machine;
3) the design weight of the left weft laying mechanism 6 is effectively reduced, and the implementation of a weight reduction design target of the weft laying machine is facilitated.
The resilient ejector 681 can be designed in various configurations to push the built-in U-shaped frame 63 all the way, but an embodiment is proposed herein that is simple in design, easy to manufacture and implement, and convenient to perform maintenance and repair operations subsequently, as follows: the elastic top unit 681 is mainly composed of a plurality of N columnar springs 6811 arranged side by side in the front-rear direction. A cylindrical spring 6811 is built into the inner cavity of the outer U-shaped frame 62 and is always resiliently compressed between the inner U-shaped member 631 and the outer U-shaped member 621 (as shown in fig. 5 and 9).
As can be clearly seen from fig. 5 and 9, the elastic ejecting sub-unit 681 is further provided with a left-position positioning column 6812 and a right-position positioning column 6813 that are applied in cooperation with the cylindrical spring 6811. The left position-limiting post 6812 is used for receiving the left end of the cylindrical spring 6811 and is embedded in the left side wall of the external U-shaped member 621. The right position-limiting post 6813 is used for engaging with the right end of the cylindrical spring 6811 and is embedded in the left side wall of the built-in U-shaped member 631. By adopting the technical scheme, on one hand, on the premise of ensuring that the cylindrical spring 6811 is firmly fixed, the left limiting column 6812 and the right limiting column 6813 cooperate with each other to effectively improve the positioning accuracy of the cylindrical spring 6811, so as to ensure that the elastic pushing force in the same direction and the same value is output relative to different built-in U-shaped parts 631 at the same time, and further ensure that the different built-in U-shaped parts have good resetting synchronism; on the other hand, the dismounting speed of the columnar spring 6811 is effectively improved, and the subsequent dismounting operation is favorably and smoothly executed.
According to the common design knowledge, the guiding subassembly 651 can adopt various design structures to realize the guiding of the displacement direction of the internal U-shaped piece 631, so as to ensure that the internal U-shaped piece 631 performs the displacement movement relative to the external U-shaped piece 621 along the left and right directions all the time, and further realize the reliable clamping of the left end of the fiber cloth strip, but an embodiment with a simple design structure, easy implementation and favorable later-stage execution of the dismounting and replacing operation is recommended here, which is specifically as follows: as shown in fig. 4-11, the guide subassembly 651 is preferably a pilot screw 6511. The pilot screw 6511 is screwed to the top wall of the external U-shaped member 621, and correspondingly, a waist-shaped pilot notch 6311 adapted to the pilot screw 6511 and extending in the left-right direction is formed in the internal U-shaped member 631.
It is known that, in view of the material characteristics of the fiber cloth strip, the pressure loss is very likely to occur when the fiber cloth strip is subjected to a rigid force, and the final weaving quality of the fiber cloth is further likely to be adversely affected. In view of this, as a further optimization of the weft laying mechanism described above, an elastic pad assembly 69 is also added. The resilient pad assembly 69 is comprised of an inner resilient pad subassembly 691 and an outer resilient pad subassembly 692 that cooperate to perform a resilient compression operation on the fabric cloth. Built-in spring washer subassembly 691 is comprised of N built-in spring washer bars 6911 removably secured to the right side wall of built-in U-shaped member 631. External spring washer subassembly 692 is comprised of N external spring washer bars 6921 removably secured to the right side wall of external U-shaped member 621 and positioned opposite internal spring washer bar 6911. Therefore, in the process that the internal U-shaped element 631 gradually approaches the external U-shaped element 621 due to the lateral elastic pushing force to clamp the left end of the fiber cloth, the internal elastic liner bar 6911 and the external elastic liner bar 6921 first contact the left end of the fiber cloth, so that the pressure loss caused by the rigid pressing force can be effectively avoided.
As a further refinement of the construction of the above-described weft laying mechanism, as shown in fig. 2 to 9, the first drive section 66 preferably includes a first rotating electric machine (not shown), a chain transmission mechanism 661, and a towing assembly 662. The towing assembly 662 is composed of N towing pieces 6621 which are matched with the external U-shaped pieces 621 and used for towing the external U-shaped pieces 621 independently in a one-to-one correspondence manner. The first rotating electric machine is hidden in the cavity of the support beam 71 and applies a dragging force to the dragging assembly 662 through a chain transmission mechanism 661. By adopting the above technical scheme, on the one hand, on the premise of ensuring that the first driving part 66 meets the basic dragging function, the first driving part has a simpler design structure, is easy to manufacture and implement, and has relatively low implementation cost; on the other hand, the phenomenon of 'dragging slip' caused by insufficient dragging force or other factors can be effectively avoided, the external U-shaped frame 62, the internal U-shaped frame 63 and the needle assembly 64 are ensured to have higher displacement precision, and the fiber cloth weft laying work is further ensured to be executed with high quality.
As is clear from fig. 7, 8, 9 and 12, a second guide member 663 is further added to the first driving portion 66. The second pilot assembly 663 includes N vertical pilot bearings 6631 and N horizontal pilot bearings 6632 detachably secured to the traveler 6621. The vertical guide bearings 6631 cooperate to eliminate play in the up-down direction of travel of the travel assembly 662 displacement on the way. The horizontal guide bearings 6632 cooperate to eliminate play in the movement of the trailing assembly 662 in the left-right direction during travel. A vertical guide rib 611 matched with the horizontal guide bearings 6632 and always supported by the horizontal guide bearings 6632 extends upwards from the top wall of the support beam 61. A horizontal guide rib 612 is extended from the support beam 61, which is matched with the vertical guide bearings 6631 and is always pressed by each vertical guide bearing 6631.
As the progress of the fiber-cloth-strip laying operation advances, the second driving portion 67 adaptively changes the output direction of the pushing-out force according to the actual laying position, so as to sequentially drive the built-in U-shaped members 631 in the respective sections in batches. As is clear from the above description, the operation sensitivity and the displacement accuracy of the second driving unit 67 have a crucial influence on the weft laying quality of the fiber cloth. In view of this, the present embodiment discloses a preferred structure of the second driving portion 67, which is mainly composed of the supporting base 671, the carrier substrate 672, the rack-and-pinion driving mechanism 673, the second speed reduction motor 674, the ejector 675, and the linear driving unit 676, as shown in fig. 13 and 14. Wherein the support base 671 is borne by the frame of the weft laying machine and is arranged at one side of the support beam 61. The carrier substrate 672 is used to mount the fixed linear drive unit 676 thereon, and performs displacement motion reciprocally in the front-rear direction under the cooperation of the rack-and-pinion drive mechanism 673 and the second reduction motor 674. The rack and pinion drive mechanism 673 is constituted by a gear 6731 and a rack 6732. The rack 6732 is disposed directly below the carrier substrate 672 and is detachably fixed to the top wall of the support base 671. The second reduction motor 674 is detachably fixed to the carrier substrate 672. The gear 6731 engaged with the rack 6732 is directly driven by the second reduction motor 674. The ejector 675 reciprocally performs a displacement motion in the left-right direction by the linear driving unit 676 to additionally drag the plural pieces of built-in U-shaped members 631 at the same time.
As is also apparent from fig. 13 and 14, a third guide member 677 is further provided in the second driving portion 67. The third aligning member 677 is composed of a left-positioned third guide subassembly 6771 and a right-positioned third guide subassembly 6772 that cooperate to align the moving direction of the carrier substrate 672. The left third guiding subassembly 6771 comprises a left sliding rail 67711 and a left sliding block 67712. The right third guiding subassembly 6772 includes a right slide rail 67721 and a right slide block 67722. The left slide rail 67711 and the right slide rail 67721 are detachably fixed on the top wall of the supporting seat 671 and are arranged in parallel. The left slider 67712 matched with the left slide rail 67711 and the right slider 67722 matched with the right slide rail 67721 are detachably fixed on the bottom wall of the bearing substrate 672.
In addition, as can also be seen from the illustration in fig. 13, the linear drive unit 676 is preferably constituted by 2 cylinders 6761 which are borne by the carrier substrate 672 and cooperate to drive the ejector 675. After the fiber cloth strip is fed into the needle assembly 64 and the left feeding mechanism 2 continues to perform the pressing action to make the left end of the fiber cloth strip freely droop into the gap formed between the group of inner U-shaped members 631 and the group of outer U-shaped members 621, the air cylinder 6761 releases the pressure to release the dragging force applied to the inner U-shaped members 631, and at the same time, the elastic potential energy of the elastic jacking sub-unit 681 opposite to the air cylinder is released to drive the group of inner U-shaped members to perform the right movement slowly and stably until the group of outer U-shaped members 621 abut against each other, thereby ensuring the end of the fiber cloth strip to be clamped reliably.
Finally, it should be noted that, as is known, the needle mounting element 641 is a wearing part, and a great deal of effort is required to be invested in the application of the weft laying machine to frequently perform maintenance or replacement operations on the wearing part, which in turn tends to reduce the working efficiency of the weft laying machine to a certain extent. In view of this, as shown in fig. 11, as a further optimization of the structure of the weft laying mechanism described above, the needle mount 641 is preferably a split design structure, which is configured by inserting N mounting seats 6411 and M card needles 6412. Each mounting seat 6411 is detachably fixed on the right side wall of the external U-shaped element 621 by screws, and M blind insertion holes for the card wire 6412 to perform insertion and matching operations extend downwards from the top wall of the external U-shaped element. When the weft laying machine is applied for a period of time, when a certain needle loading piece 641 is damaged integrally or certain carding wires 6412 attached to the single needle loading piece 641 are worn or bent, only the damaged component or the damaged piece needs to be replaced with new ones in a targeted manner, so that the weft laying machine can be effectively ensured to have better maintainability, and the later maintenance cost is reduced.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
