Abstract

The utility model relates to a yarn-gripping type end yarn retaining device of a bare spindle of a ring spinning frame. The yarn-gripping type end yarn retaining device of the bare spindle of the ring spinning frame comprises a shove claw (1) and yarn grippers (2), wherein a half circle of which the diameter a is 20mm is formed in the shove claw (1); a chamfer is formed on each of the upper surface and the lower surface of the head part of the shove claw (1) respectively, so that a wedge type is formed; the left outer side and the right outer side of the shove claw (1) are symmetrically provided with two yarn grippers (2); each yarn gripper (2) is made of 0.4mm thick spring steel; the width of each yarn gripper (2) is less than the thickness of the wedge part of the shove claw (1); and the two symmetrically yarn grippers (2) bending back towards the left and the right respectively form a 40-degree included angle at the 20mm-diameter half circle. The yarn-gripping type end yarn retaining device of the bare spindle of the ring spinning frame is simple in structure and reliable in yarn breakage, and can effectively grip an end yarn; therefore, the problem of low yarn breakage rate during the production of coarse yarn and pure chemical fiber products is solved, the working difficulty is decreased greatly for doffers, the working efficiency is improved and the labor cost is reduced; and since the implementation of the device is helpful to the promotion of the overall level of the textile industry and the improvement of industrial competitiveness, the device has wide market prospect.

Description

Ring throstle polished rod spindle yarn clipping formula is stayed the tail yarn feeding device

Technical field

The utility model relate to a kind of for textile industry stay the tail yarn feeding device, specifically, related to a kind of ring throstle polished rod spindle yarn clipping formula and stayed the tail yarn feeding device.

Background technology

Cotton spinning ring throstle light spindle blade spindle is traditional and always extremely cotton spinning enterprise welcome of low price because of it, the short machine of cotton spinning ring throstle accounts for more than 90% of cotton spinning frame total amount, and the configuration of fine spining machine light spindle blade spindle accounts for short more than 95% of machine of ring throstle, the traditional mode of doffing of short car is doffed for manual, the tail yarn is wrapped in the cop bottom, along with pulling up of cop the tail yarn twined to stay on the spindle blade when doffing and let the hair grow, it is many that the method causes spindle blade to twine yarn, spool is inserted not on earth, the problems such as automatic winder change difficulty, and doffer's working strength is large, the doffer of the textile enterprise difficulty of advertising for workers.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of ring throstle polished rod spindle yarn clipping formula and stays the tail yarn feeding device, this device can effectively be clamped the tail yarn, again can be when doffing tube drawing effective broken yarn, broken yarn is reliable, the low problem of broken yarn rate has solved the problem of staying tail yarn difficulty when ring throstle light spindle blade spindle is joined collective doffing simultaneously when having solved the fine production of low count yarn and purifying.

The technical solution of the utility model: a kind of ring throstle polished rod spindle yarn clipping formula is stayed the tail yarn feeding device, it comprises: shovel pawl 1, yarn gripper 2, shovel and be provided with a diameter a on the pawl 1 semicircle that is 20mm, the upper and lower surface of shovel pawl 1 head is respectively led a chamfering, form a wedge-like, shovel pawl about 1 outsides are symmetrically arranged with two yarn grippers 2, the material of described yarn gripper 2 is the thick spring steel of 0.4mm, width is less than the thickness of shovel pawl 1 wedge-like part, and two yarn grippers 2 of symmetrical left and right sides replication form one 40 ° angle at diameter 20mm semicircle place.

The utility model compared with prior art has following beneficial effect: the utility model is simple in structure, broken yarn is reliable, can effectively clamp the tail yarn, the low problem of broken yarn rate reduces doffer's working strength greatly when having solved the fine production of low count yarn and purifying, increases work efficiency, reduce the recruitment cost, this device implement the integral level that helps promote textile industry, improve industrial competition, have wide market prospects.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is work schematic diagram of the present utility model.

The specific embodiment

Below by the drawings and specific embodiments implementer's case of the present utility model is described in further detail: as shown in Figure 1, a kind of ring throstle polished rod spindle yarn clipping formula is stayed the tail yarn feeding device, it comprises: shovel pawl 1, yarn gripper 2, shovel and be provided with a diameter a on the pawl 1 semicircle that is 20mm, in order to get out of the way the spindle position, the upper and lower surface of shovel pawl 1 head is respectively led a chamfering, form a wedge-like, so that between insertion spool bottom and the spindle, shovel pawl about 1 outsides are symmetrically arranged with two yarn grippers 2, the material of described yarn gripper 2 is the thick spring steel of 0.4mm, width is less than the thickness of shovel pawl 1 wedge-like part, and two yarn grippers 2 of symmetrical left and right sides replication form one 40 ° angle at diameter 20mm semicircle place, be wrapped in the tail yarn on the wharve stub when doffing to clamp.

As shown in Figure 2, after spool spins completely, spindle slows down, ring rail is descending, the full packages halching drops on the tail yarn wharve stub root of spindle bar dish assembly behind a circle, require to twine 3 ~ 4 circles, at this moment, main motor stops, and described shovel pawl is combined under the promotion of cylinder and linkage, and the 40 degree angles that form by the upper yarn gripper of described shovel pawl combination will be wrapped in 3 ~ 4 circle tail yarns of wharve stub root and clamp, when doffed gas frame or Doffing manipulator of cop pulls out away, the yarn that cop links to each other with the tail yarn is pulled off, and the other end that links to each other with the tail yarn on the steel traveler is clamped by yarn gripper, after spindle reinserts blank pipe, the combination of shovel pawl is withdrawed from, starting operation forms and reels, beginning new round spinning circulation.

This device source of the gas is power, adopt linkage, the yarn that cylinder moving drivening rod mechanism is wrapped on the light spindle blade spindle shovel pawl combination when doffing produces the active force of a clamping, thereby realize effect of the present utility model, in addition, the change requirement of road automatic winder after the formed broken end pattern of the utility model is fit to very much.

Claims

1. a ring throstle polished rod spindle yarn clipping formula is stayed the tail yarn feeding device, it comprises: shovel pawl (1), yarn gripper (2), it is characterized in that: shovel and be provided with a diameter a on the pawl (1) semicircle that is 20mm, the upper and lower surface of shovel pawl (1) head is respectively led a chamfering, form a wedge-like, the outside is symmetrically arranged with two yarn grippers (2) about shovel pawl (1), the material of described yarn gripper (2) is the thick spring steel of 0.4mm, width is less than the thickness of shovel pawl (1) wedge-like part, and two yarn grippers (2) of symmetrical left and right sides replication form one 40 ° angle at diameter 20mm semicircle place.
