Abstract

The utility model discloses a winding equalizing device, which can ensure stable tension of yarns in the spiral yarn winding process. The winding equalizing device comprises a tension equalizing frame arranged on a machine beam; a supplementary difference mandrel and at least one insertion hole distributed at the periphery of the supplementary difference mandrel are arranged on the tension equalizing frame; a supplementary difference swing link and a torsion spring are movably sleeved on the supplementary difference mandrel; one end of the torsion spring is propped against the supplementary difference swing link, and the other end of the torsion spring is inserted into the insertion hole; a supporting shaft is arranged at the end of the supplementary difference swing link; and a swing yarn penetration guide wheel is arranged on the supporting shaft. The supplementary difference swing link vertically swings under the action of the torsion spring in the spiral yarn winding process, and the length of the yarns from the output point of a yarn conveying device to the winding point is always invariable; therefore, the linear velocity of the yarn conveying device is constant and the tension of the yarns is invariable, the periodic uneven twisting of the yarns is effectively avoided, and the quality of the finished yarns is greatly improved.

Description

Winding balance device

Technical field

The utility model relates to a kind of winding balance device, relates in particular to a kind of polyamide fibre, the winding balance device of polyester filament when two-for-one twister is twisted of weaving cord fabric.

Background technology

When the twisting of existing industrial long filament utilization double twisting technology is produced, its yarn of having twisted is directly exported behind " overfeeding wheel " this yarn-feeding device and is arrived winding point, mound bobbins and back and forth moves silk motion by silk shifting rod under the driving of friction roller, finish the helix line of yarn and reel.Its shortcoming is: an overfeeding wheel output point and two flex points of moving the silk motion constitute a triangle, one side in winding process yarn by the leg-of-mutton another side that is rocked to.Be engraved in variation during the surface side warp line tension, shaping mid point tension force minimum increases to maxim gradually during to flex point, be unfavorable for the yarn moulding.On the other hand, because yarn is from mid point to two flex point, the length of its yarn is different, but overfeeding wheel self yarn feeding amount is identical, and the winding process linear velocity is identical, thus yarn by mid point to the reciprocal process of flex point, yarn is forced to go up slippage from the overfeeding wheel and pulls out, cause periodic uneven twist, and traverse is big more, above-mentioned quality problems are serious more.

The utility model content

Technical problem to be solved in the utility model is: a kind of tension force unmodified winding balance device that can guarantee yarn in the helix line winding process of yarn is provided.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: winding balance device, comprise: be arranged on the equalization of strain frame on the machine beam, the equalization of strain frame is provided with make up the difference mandrel and at least one and is distributed in jack around the mandrel of making up the difference, make up the difference and be movably installed with make up the difference fork and torsion spring on the mandrel, one end of torsion spring is resisted against on the fork of making up the difference, the other end of torsion spring is inserted in one of them jack, the make up the difference end of fork is provided with bolster, and bolster is provided with swing silk rolling guide wheel.

Described concrete set-up mode of making up the difference mandrel and make up the difference fork and torsion spring is: the afterbody of the fork of making up the difference is provided with rotary sleeve, and the rotary sleeve movable set is on the mandrel of making up the difference, and the torsion spring movable set is on rotary sleeve.

Upper and lower side at described swing silk rolling guide wheel on the described equalization of strain frame is respectively arranged with silk rolling guide wheel and following silk rolling guide wheel.

The beneficial effects of the utility model are: owing to be provided with winding balance device between winding point and yarn-feeding device, make yarn be rocked to by leg-of-mutton one side in the process of another side, the fork of making up the difference swings up and down under the effect of torsion spring, guaranteed that the length from the output point of yarn-feeding device to yarn between the winding point remains constant, avoided yarn on yarn-feeding device, to be forced to slippage by force, make that the linear velocity constant of yarn-feeding device is constant, the tension force of yarn remains unchanged, avoid periodic uneven twist effectively, improved the yarn qualities after the moulding greatly.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.

As shown in Figure 1, winding balance device described in the utility model, comprise: be arranged on the equalization of strain frame 4 on the machine beam 1 and the fork 52 of making up the difference, described equalization of strain frame 4 is provided with make up the difference mandrel 51 and eight and is distributed in jack 41 around the mandrel 51 of making up the difference, make up the difference and be movably installed with make up the difference fork 52 and torsion spring 54 on the mandrel 51, as shown in Figure 2, its concrete set-up mode is: the afterbody of the fork 52 of making up the difference is provided with rotary sleeve 521, rotary sleeve 521 movable sets are on the mandrel 51 of making up the difference, and torsion spring 54 movable sets are on rotary sleeve 521; One end of torsion spring 54 is that movable end 541 is resisted against on the fork 52 of making up the difference, the other end of torsion spring 54 is that fixed end 542 is inserted in one of them jack 41---referring to Fig. 2 and shown in Figure 3, make the torsion spring 54 and the tension force of yarn 20 adapt, the make up the difference end of fork 52 is provided with bolster 522, and bolster 522 is provided with swing silk rolling guide wheel 53; In the present embodiment, the upper and lower side at swing silk rolling guide wheel 53 is respectively arranged with silk rolling guide wheel 19 and following silk rolling guide wheel 18 on the described equalization of strain frame 4.
