The ultrasonic slitting machine is used for cutting materials, has the advantages of automatic edge sealing, no melting change, no burrs and no loose edges of a cutter, ensures that the cut of the materials after cutting is soft, beautiful and flat, and can effectively improve the cutting efficiency. Therefore, the ultrasonic slitting machine is widely applied to the cutting process summary of woven belts, trademark tapes and the like prepared from terylene, chinlon, artificial fabrics, natural rubber and the like.

The object stage is used for carrying materials cut by the belt and abuts against the cutter vibrated by ultrasonic in the actual use process, so that the object stage is also called as an oscillating platform. In the actual use process, the high-frequency vibration cutter not only can effectively cut materials, but also can leave cutting impressions on the objective table. As the number of uses increases, a series of indentations perpendicular to the cutting direction of the tool will eventually be left on the stage. The indentations can be slightly concave, and the cutting efficiency and the cut smoothness of the cutter during cutting are affected. Therefore, when a significant series of indentations has occurred, the stage should be ground flat and then used again. Usually, after grinding for several times, the surface of the object stage is too worn to be used for further grinding, and at the moment, the object stage needs to be replaced. However, the carrier itself is expensive and frequent replacement of the carrier will significantly increase the production costs.

Detailed Description

In order that the utility model may be more fully understood, reference will now be made to the following description. Preferred embodiments of the present invention are presented herein. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items. As used herein, "plurality" includes two and more than two items. As used herein, "above a certain number" should be understood to mean a certain number and a range greater than a certain number.

The mechanical type divides the strip machine to lean on the cutting edge and wait to cut apart the relative movement of pressure between the material to the realization is to the cutting apart of material, and the ultrasonic wave divides the strip machine to be different with the principle of traditional mechanical type branch strip machine. In the working process of the ultrasonic slitting machine, the temperature of the cutter is increased to cut materials mainly under the action of ultrasonic vibration of the cutter. Ultrasonic vibration can make and produce high frequency collision between cutter and the objective table, therefore the ultrasonic wave divides the strip machine can leave the cutting indentation of a long cluster of perpendicular to cutter cutting direction on the objective table in the use, in order to guarantee the planarization on objective table surface, all need grind the flat processing to the objective table after using for a certain length of time usually. However, the inventors have found that the cutting impressions are formed only in a strip-shaped area of the stage surface, a part of which is near the middle, and no impressions are formed in the areas on both sides of the strip-shaped area.

Based on this finding, the inventors propose a technical idea of extending the service life of the stage. Specifically, according to one embodiment of the utility model, an ultrasonic slitting machine comprises a machine frame, an object stage, a cutter and a cutter holder; the objective table is used for bearing materials to be cut, the cutter holder is connected to the rack, the cutter is arranged on the cutter holder, the cutting direction of the cutter is longitudinal, the cutter is adjustable in longitudinal position relative to the objective table, and the cutter is used for cutting the materials arranged on the objective table.

The "cutting direction" is the direction determined by the cutting line of the blade, and the cutting line has two opposite directions, both of which can be the cutting direction.

In the ultrasonic slitting machine of the embodiment, the cutter is arranged to move longitudinally relative to the object stage so as to prolong the service life of the object stage. For example, when the cutting device is used for a certain period of time, a part of the surface of the object stage forms a long string of transverse cutting impressions perpendicular to the cutting direction of the cutting knife, and the longitudinal position of the cutting knife can be adjusted to ensure that the cutting knife is pressed on the part without the cutting impressions on the object stage when cutting materials. A stage may be used multiple times and form multiple transverse series of indentations before it is required to grind the stage flat. Compared with the traditional technology that the object stage is ground and reused after a series of indentations are formed, the object stage in the ultrasonic slitting machine in the embodiment can be ground and reused after a plurality of parallel indentations are formed, and therefore the service life of the object stage can be prolonged by multiple times. The degree of lifetime increase depends in particular on the number of stage indentation formations before a single stage grind.

It will be appreciated that for an ultrasonic slitter there should be a source of ultrasonic waves for ultrasonically vibrating the cutters.

The cutter can move relative to the rack along the cutting direction of the cutter. For the convenience of understanding, the cutting direction of the cutter is taken as the longitudinal direction, and the direction perpendicular to the cutting direction of the cutter on the horizontal plane is taken as the transverse direction.

In traditional ultrasonic slitting machine, the width of waiting to divide the strip material usually need be adjusted, need realize this moment through the horizontal position of adjusting the cutter, but in order to keep the cutter not to take place the skew when ultrasonic vibration, can fix the cutter position on vertical usually. In order to prolong the service life of the objective table, the ultrasonic slitting machine in the embodiment is specially changed into that the position of the cutting knife relative to the objective table in the longitudinal direction is adjustable.

The specific manner in which the position of the cutting knife relative to the object stage is adjustable may be, for example, to control the cutting knife not to move, so that the object stage moves. However, in the conventional ultrasonic slitting machine, the stage itself has a large mass, and it is inconvenient to move the stage, and the stage is not usually moved in order to ensure stability. Therefore, the position of the cutting knife relative to the object stage can be adjusted in a specific way, for example, the knife holder is controlled to be kept immovable in the longitudinal direction relative to the machine frame, so that the cutting knife can move in the longitudinal direction relative to the knife holder; in another example, the cutting blade is controlled to be longitudinally immovable relative to the blade holder, so that the blade holder, at least part of which is provided with the cutting blade, can be longitudinally moved relative to the machine frame. It will be appreciated that in actual design consideration should preferably be given to controlling the movement of the cutting or seating blade.

Optionally, in one particular example, the cutting blade is fixed relative to the blade holder in a longitudinal direction in the horizontal plane, and the blade holder is adjustable relative to the stage in the longitudinal direction in the horizontal plane. Because the cutter can produce ultrasonic vibration at the course of the work, consequently with the cutter design for the blade holder on the cutting direction of cutter is static, can reduce the stress that the connection position between cutter and the blade holder received, avoid as far as possible setting up the cutter to the extra damage that can bring the machine relatively frame longitudinal movement.

Further, in some conventional ultrasonic slitting machines, the tool apron can also move transversely relative to the machine frame in a direction perpendicular to the cutting direction of the cutter as required, and then a connecting piece can be further arranged to avoid damage caused by relative movement between the tool apron and the machine frame. The objective table and the connecting piece are both arranged on the rack, the tool apron is connected to the rack through the connecting piece, and the tool apron is adjustable in position in the longitudinal direction in the horizontal plane relative to the connecting piece.

Specifically, in order to further understand the ultrasonic slitting machine in the above embodiments, referring to fig. 1, an embodiment of the ultrasonic slitting machine includes a frame 110, an object stage 120, a cutter 130, and a cutter seat 140. The objective table 120 is disposed at the bottom to support the cloth to be cut.

The position of the connecting member 150 relative to the frame 110 in the cutting direction is fixed, and the position of the tool holder 140 relative to the connecting member 150 in the longitudinal direction is adjustable.

The "longitudinal direction" and the "transverse direction" are two mutually perpendicular directions on a horizontal plane. Specifically, please refer to the three-dimensional coordinate system identified in fig. 1, wherein the x direction is perpendicular to the paper surface, the y direction and the z direction are located on the paper surface, the x direction perpendicular to the paper surface is a longitudinal direction, the y direction located on the paper surface is a transverse direction, and the longitudinal direction and the transverse direction refer not only to the longitudinal direction and the transverse direction on the horizontal plane where the cutting position of the cutter is located, but also to the longitudinal direction and the transverse direction on other horizontal planes.

The position of the tool holder 140 relative to the connecting member 150 in the longitudinal direction can be adjusted in various ways. The embodiment of the present invention is described by taking one of the examples. Referring to fig. 2 to 5, fig. 2 shows a front view of the insert seat 140, fig. 3 shows a top view of the insert seat 140, fig. 4 shows a cross-sectional view of an AA 'surface of the insert seat 140, and fig. 5 shows a cross-sectional view of a BB' surface of the insert seat 140. The region with parallel oblique lines in fig. 2 shows an internal cross-sectional view taken along the region.

Referring to fig. 2 and 3, in a specific example, the tool holder 140 is provided with a movable through hole 141 extending along the cutting direction, and the tool holder 140 is movably connected to the connecting member 150 through the movable through hole 141. One end of the movable through hole 141 is opened on a side surface of the tool holder 140 close to the cutter 130, and the other end is opened on a side surface of the tool holder 140 close to the connecting member 150. Through the mode of opening movable through-hole 141 on blade holder 140, realize that the relative position between blade holder 140 and connecting piece 150 is adjustable, reduce the transformation to original equipment itself as far as possible.

To facilitate understanding of the specific connection between the tool holder 140 and the connecting member 150, please refer to fig. 6 to 9, in which fig. 6 shows a partial front view of the connecting member 150, fig. 7 shows a partial top view of the connecting member 150, fig. 8 shows a cross-sectional view of the AA 'surface of the connecting member 150, and fig. 9 shows a cross-sectional view of the BB' surface of the connecting member 150.

In consideration of the ultrasonic vibration of the cutter 130 during actual use, it is necessary to maintain the fixation between the tool holder 140 and the connecting member 150 during use.

In one specific example, the ultrasonic slitter further comprises a fixing hole 151 and a fixing member 160, and the fixing member 160 and the fixing hole 151 are used together to fix the tool post 140 to the connecting member 150. In the actual assembly process, the fixing member 160 first extends into the movable through hole 141 of the tool holder 140, and then enters the fixing hole 151 of the connecting member 150 to complete the fixing. When the position of the tool apron 140 needs to be adjusted, the fixing member 160 and the fixing hole 151 may be detached first, the tool apron 140 is adjusted in position by means of the movable through hole 141, and finally the fixing member 160 is inserted into the fixing hole 151, and the tool apron 140 is fixed on the connecting member 150 again.

Fig. 6 to 7 show a specific example of providing the fixing hole 151, wherein the fixing hole 151 is opened on the connecting member 150, the fixing hole 151 is opened opposite to the movable through hole 141, and the fixing member 160 is detachably connected to the fixing hole 151 after passing through the movable through hole 141. In practice, the fixing member 160 is easily moved to separate the tool holder 140 from the connecting member 150. In another specific example, the fixing member 160 may be disposed on the connecting member 150, the fixing hole 151 may be separately disposed on another component, and the fixing member 160 may extend into the fixing hole 151 of the component after extending into the movable through hole 141 to connect the tool holder 140 and the connecting member 150. Alternatively, the fixing hole 151 is a screw hole having a screw thread on an inner wall, and the fixing member 160 is a screw adapted to the screw hole. When the fixing member 160 is provided on the connection member 150, the fixing hole 151 may be separately provided on the additional nut.

In addition, in one specific example, the connecting member 150 further has a frame connecting hole 152, and correspondingly, the frame 110 has a projection corresponding to the frame connecting hole 152, and the connecting member 150 is connected to the frame 110 through the frame connecting hole 152 and the projection.

For example, as shown in fig. 3, there are four sets of two movable through holes 141, and two movable through holes 141 are spaced apart from each other in the longitudinal direction. The two movable through holes 141 which are longitudinally arranged at intervals are arranged, so that the longitudinal movement range of the tool apron 140 can be widened as much as possible on the premise of keeping the integrity of the long tool apron 140.

Further, corresponding to the arrangement of the movable through holes 141, the connecting member 150 is also provided with a plurality of sets of fixing holes 151 respectively corresponding to the movable through holes 141, and each set of fixing holes 151 corresponds to one movable through hole 141. Each group of fixing holes 151 includes two fixing holes 151, and the two fixing holes 151 are respectively aligned at two ends of the corresponding movable through hole 141. The movable through hole 141 is provided as described above to improve the connection stability between the connecting member 150 and the holder 140 mainly in the case of widening the longitudinal movement range of the holder 140. For example, when the fixing member 160 moves from one end of one of the movable through holes 141 to the other end, two fixing members 160 can still participate in the fixed connection between the connecting member 150 and the tool holder 140 in one set of the movable through holes 141, so that the stable connection between the connecting member 150 and the tool holder 140 can be maintained. If only one fixing member 160 is connected between the connecting member 150 and the tool holder 140 in one set of the movable through holes 141, the connecting portion between the connecting member 150 and the tool holder 140 is subjected to an excessive stress, and thus the connecting portion is easily loosened.

Further, the two movable through holes 141 of the set of movable through holes 141 may be configured to have the same shape, so that the longitudinal movement range of the tool holder 140 can be further increased while the two fixing members 160 are connected to the set of movable through holes 141.

In one specific example, the cutting tool further comprises a tool rest 170, the cutting tool 130 is detachably connected to the tool rest 170, and the tool rest 170 is connected to the tool holder 140.

In addition, the tool holder 140 further has a plurality of guide mounting holes 143, the guide mounting holes 143 may be provided, and the guide is also provided with a protrusion adapted to each guide mounting hole 143, and the guide is fixedly connected to the tool holder 140 through the guide mounting holes 143 and the protrusions.

In one specific example, there are a plurality of cutting knives 130, a plurality of cutting knives 130 are arranged in parallel, and two adjacent cutting knives 130 are arranged at intervals.

Fig. 10 shows a top view of the stage 120 after a prolonged use forming a series of transverse first indentations 121. The cutting blade 130 is not longitudinally movable relative to the stage 120 as in the conventional technique, and therefore only forms a series of transverse indentations. After the stage 120 of the ultrasonic slitter in the above embodiment forms a series of indentations, one or more series of transverse indentations may be formed in addition to the existing first indentation 121 by adjusting the position of the cutter 130 relative to the stage 120 in the longitudinal direction. For example, in fig. 11, in the ultrasonic slitting machine according to the above embodiment, a second indentation 122 and a third indentation 123 can be formed on the stage 120. If the stage 120 is declared obsolete after 5 passes through the smoothing, only 6 series of indentations can be made on the stage 120. However, if the ultrasonic slitting machine of the above embodiment is used, 3 series of indentations can be formed before each smoothing, 18 series of indentations can be generated on the stage 120, and the effective service life can be prolonged by 3 times. It will be appreciated that the above data is provided as an example to aid understanding, and that in practice the specific values will vary for different sizes and models of stage 120.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
