Description

Carry the conveyer belt of the ribbon that should gather
Technical field
The present invention relates to a ventilative conveyer belt that is designed to woven belt, be used for carrying the suction slot of the ribbon that should gather by a set district on the spinning machine, this conveyer belt has many by the warp thread of ribbon transporting direction with transverse to the weft yarn of ribbon throughput direction.
Background technology
When one the drawn fiber bar directly obtain spinning twisting in the right downstream of the front roller of drafting assembly, then produce a so-called spinning triangle at the right jaw line of front roller.Making like this, the drawn fiber bar leaves drafting assembly with certain width and twists into a yarn than minor diameter.The spinning triangle contains the edge fiber that is clipped in inadequately in the twisted yarn, and the latter seldom or not plays effect to the intensity of resultant yarn.Therefore trended towards a so-called set of the arranged downstream district at drafting assembly in recent years, the set district is the jaw line boundary with outgoing side.Spinning twisting is assigned on the yarn then.Fiber carries out boundling or set in the set district, ribbon tapers to when leaving last jaw position and no longer produces fearful spinning triangle like this.The yarn of being produced is more even, solid and less filoplume.
Have the set district of many different designs to be used for the set of ribbon, the form of implementation of some of them practicality is, the ribbon that should gather is to carry a suction slot by the set district by ventilative conveyer belt.
The prior art of above-mentioned this conveyer belt can be learnt from DE 198 37 182 A1.Known conveyer belt is to be made into thin plastic cord, and fine and closely woven hole is arranged, and therefore says from the manufacturing principle and breathes freely.Warp thread has identical spacing and identical diameter respectively with weft yarn.
This conveyer belt that is designed to woven belt must satisfy different requirements.One, the eyelet that warp thread and weft yarn constitute should have enough big, make conveyer belt guarantee the charge air that set is required.Its two, the pore of fabric should be little to such degree, promptly carry and every fiber of the ribbon gathered is unlikely and passes the fabric eyelet and be sucked as the loss fiber.For this reason, people are once with regard to these two self-contradictory requirements, strive to find a kind of suitable inner feelings way of tearing open.
Summary of the invention
Task of the present invention is, creates the ventilative conveyer belt that above-mentioned this class is designed to woven belt, and it guarantees enough big charge air on the one hand, and stops suction loss fiber on the other hand as far as possible.
The terms of settlement of this task is that two mutual clear spacings of warp thread should be greater than the clear spacing between two weft yarns.
By the rectangle eyelet that the design plan of this belt strap produces, its less side is towards transporting direction, and its bigger side is transverse to transporting direction.Because the less clear span of transporting direction, fibre loss obviously reduces.In addition, because laterally bigger clear span has an abundant big charge air, therefore the rectangle eyelet cross-sectional plane according to conveyer belt of the present invention can have the identical size of square cross section of conveyer belt as is known.Therefore can dwindle two clear spacings between the weft yarn, and amplify clear spacing between two warp thread, thereby reach the less loss of fiber for balance.In fact, weft yarn is to interweave by compact arranged warp thread one by one when weaving, and sees that aspect warp thread it is comparatively few to introduce weft yarn.
In the technical scheme of the present invention, the clear spacing between two warp thread is greater than its diameter.According to said method, the unlimited air-flow cross-sectional plane of conveyer belt reaches more than 30%.When warp thread and diameter of the weft yarn during all less than 0.08 millimeter, this measure can also be supported.Well-proportioned air-flow be can obtain like this, thereby good set effect and good yarn quality produced.
Because conveyer belt slides through a sliding surface, can produce certain wearing and tearing.Because getter action be along with the time can reduce, as flyings or stick to this component of cleaning of lamination coating.Therefore, be preferably, warp thread and weft yarn adopt PEEK (polyetheretherketone) fiber respectively.Obtain the actual shrink-proof conveyer belt in a kind of very abrasion resistant washing back like this.
Have rum point for fear of rotating transportation, can produce a kind of conveyer belt of annular.Even a kind of overlap joint that passes through forms very little rum point, also mean a micro gap, fiber can firmly be clamped in the slit.If this woven belt is made into the endless belt, just can avoid the phenomenon that occurs.
Other advantages of the present invention and feature see a following embodiment explanation for details.
Description of drawings
The cut-away section lateral plan at position, Fig. 1 one set district;
Fig. 2 has several component omission not illustrate according to the set district front elevation of arrow II direction among Fig. 1;
Fig. 3 is according to the special enlarged drawing of Fig. 2 part lateral plan of woven conveyer belt of the present invention.
The specific embodiment
Fig. 1 and Fig. 2 represent the cross sectional drawing of within the scope of the present invention a spinning machine, particularly ring spinner.It is right with the apron of following apron 3 compositions with the upper leather ring 4 of its upstream arrangement to 2 to see that from figure the terminal area of drafting assembly 1 is equipped with front roller.Front roller contains one to 2 and runs through the machine length direction by the fluted roll 5 of transmission and a roller 6 that is configured to each spinning spindle position.Front roller constitutes the jaw line 7 of drafting assembly and stops its previous draft zone 2.
Ribbon or rove 8 move ahead to transporting direction A in drafting assembly 1 by known way, are drawing to till the number of requirement.A drawing-off, but untwisted ribbon 9 directly is created in the downstream of preceding jaw line 7.
If immediately to ribbon twisting, then fearful spinning triangle occurs this moment at preceding jaw line 7.Therefore, one of the draft zone downstream of the ribbon 9 of drawing-off set district 10 at first is that the avris by its fiber compiles and boundling or set, no longer forms the triangle that spins in the twisting so afterwards.
Find out that from Fig. 2 the suction channel 11 that is designed to hollow abnormity is to be positioned at draft zone 10, it extends to many spinning spindle positions.Suction channel 11 is preferably installed a vacuum connection tube 12 that leads to the negative pressure source of not representing on the figure through every joint machine and on an appropriate location.
In set district 10, the exterior contour of suction channel 11 is designed to sliding surface 13, and ventilative conveyer belt 14 is promptly slided on this sliding surface.Conveyer belt 14 relates to a kind of tiny eyelet flimsy material band that has, and hereinafter also will be described in detail, and conveyer belt carries the ribbon that should gather by set district 10, and this moment, ribbon 9 was drawn onto on the conveyer belt 14.
Operation is through tension element 15 on the side of gathering district 10 dorsad for conveyer belt 14, and tension element is also aimed at conveyer belt 14 in side surface direction.
Have one to betransported the suction slot 16 that covers with 14 on sliding surface 13, it extends facing to transporting direction A slightly inclined, ribbon 9 twisting that slightly helps the set effect that additionally obtains on the edge at suction slot 16 superposeing when gathering like this.
The terminal in set district 10 is to be subjected to limiting by a gripping roller 17 of conveyer belt 14 frictional transmissions.Grip roller 17 and be pressed on conveyer belt 14 and the suction slot 11, form so-called output jaw line 18, it plays only sth. made by twisting effect towards spinning twisting, and promptly ribbon 9 is not subjected to any twisting in set district 10.Suction slot 16 is close near the output jaw line 18.
The spun yarn 19 that forms is directly being exported the acquisition spinning twisting of jaw line 18 downstreams, and this moment, yarn was transported to the twisting mechanism of not representing among the figure by outbound course B, and for example one is encircled ingot.
Because conveyer belt 14 is with conveying fibre rod above it 9, operation is through suction slot 16 below it, and its danger is, the single fiber of ribbon 9 from the fabric eyelet enter into suction channel " the inside and continue to arrive in the aspirator.Several this loss fibers and be attached to dust on the fiber and may hang and be trapped on the conveyer belt 14 have disturbed the set effect, just can cause changing the characteristic of yarn along with the time.Therefore, how this conveyer belt that is fabricated to woven belt designs, and will be described below with the Fig. 3 that amplifies.
The fabric of conveyer belt 14 is by forming by the warp thread 20 of transporting direction A with transverse to the weft yarn 21 of transporting direction A.These warp thread 20 and weft yarn 21 commonly adopt polyamide filament, but it is better also can to use PEEK (polyetheretherketone) silk.The alleged material of the latter is wear-resisting especially.
Warp thread 20 and weft yarn 21 interweave, and clear spacing x is greater than the clear spacing y between two adjacent weft 21 between two adjacent warp thread 20.Spacing x can be many times of spacing y.Eyelet in the fabric is little rectangular opening 22 like this, and its less limit is equivalent to spacing y, and along transporting direction A, and its bigger limit is to extend transverse to transporting direction A, is equivalent to spacing x.Utilize this structure, rectangle eyelet 22 has such cross-sectional plane, and its sizableness is in the fabric eyelet of known so far square cross section, but former square eyelet is to stop incessantly useless fiber.By dwindling clear spacing y, the danger of useless fiber is significantly little, amplifies two clear spacing x between the warp thread 20 simultaneously with this, provides enough big charge air to pass through conveyer belt 14.
The fact shows, the clear spacing x between two warp thread 20 is greater than its diameter d LBe advantageous.This diameter preferably below 0.8 millimeter, is equivalent to the diameter d of weft yarn 21 Q
Fig. 3 has also showed four adjacent fibers 23 of fiber 9, see from figure, according to design-calculated belt strap of the present invention, chopped fiber 23 more lacks than endeavouring to absorb the useless method of spending by the eyelet of fabric so far, does not need to reduce but gather needed charge air.
