Abstract

The invention relates to a polished rod spindle yarn gripping type tail yarn remaining device for a ring spinning frame. The device comprises a spade claw (1) and two yarn grippers (2); the spade claw (1) is provided with a semicircle of which the diameter alpha is 20 millimeters; a chamfer is formed on each of the upper and lower surfaces of the head of the spade claw (1), and the spade claw (1) is in a wedge shape; and the two yarn grippers (2) are symmetrically arranged on the left and right outer sides of the spade claw (1), the yarn grippers (2) are made of spring steel with the thickness of 0.4 millimeter, the width of each yarn gripper (2) is smaller than the thickness of the wedge-shaped part of the spade claw (1), and the two yarn grippers (2) which are symmetrical and are bent leftwards and rightwards form an included angle of 40 degree at the semicircle with the diameter of 20 millimeters. The device is simple in structure and reliable in yarn breakage, and can effectively clamp tail yarn; the problem of low yarn breakage rate when coarse yarn and pure chemical fiber products are produced is solved, the working intensity of a doffer is greatly reduced, the working efficiency is improved, and the labor cost is reduced; and the device is beneficial to promoting the overall level of the textile industry, improves industrial competition, and has a broad market prospect.

Description

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

Technical field

The present invention relates to a kind of for textile industry stay tail yarn feeding device, specifically, related to a kind of ring throstle polished rod spindle yarn clipping formula and stayed tail yarn feeding device.

Background technology

Cotton spinning ring throstle light spindle blade spindle is because it is traditional and low price extremely cotton spinning enterprise welcome always, the short machine of cotton spinning ring throstle accounts for the more than 90% of cotton spinning frame total amount, and the configuration of fine spining machine light spindle blade spindle accounts for the more than 95% of the short machine of ring throstle, what short car was traditional doffs mode for doffing by hand, tail yarn is wrapped in cop bottom, while doffing, along with pulling up of cop, tail yarn is twined to stay on spindle blade 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 by this invention is to provide a kind of ring throstle polished rod spindle yarn clipping formula and stays tail yarn feeding device, this device can effectively be clamped tail yarn, again can be in the time doffing tube drawing effective broken yarn, broken yarn is reliable, while having solved the fine production of low count yarn and purifying, 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.

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

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

Brief description of the drawings

Fig. 1 is structural representation of the present invention;

Fig. 2 is work schematic diagram of the present invention.

Detailed description of the invention

Below by the drawings and specific embodiments, implementer's case of the present invention is described in further detail: as shown in Figure 1, a kind of ring throstle polished rod spindle yarn clipping formula is stayed tail yarn feeding device, it comprises: shovel pawl 1, yarn gripper 2, on shovel pawl 1, be provided with the semicircle that a diameter a is 20mm, in order to get out of the way 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 spindle, shovel pawl 1 outside, left and right is symmetrically arranged with two yarn grippers 2, the material of described yarn gripper 2 is the spring steel that 0.4mm is thick, width is less than the thickness of shovel pawl 1 wedge-like part, two yarn grippers 2 of symmetrical left and right replication form the angle of 40 ° at diameter 20mm semicircle place, while doffing to clamp, be wrapped in the tail yarn on wharve stub.

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

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

Claims

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