Abstract

The utility model provides a drop wire piece for loom warp stop motion, including the drop wire piece body, drop wire piece body upper end is equipped with rectangular slotted hole, and drop wire piece body middle part is equipped with the warp hole to the plane of crossing drop wire piece body 1/2 thickness is the plane of symmetry, along the vertical central line direction of drop wire piece body, and a lateral wall in warp hole is 0.5-1.5 degrees of bending forward, and another lateral wall in warp hole is 0.5-1.5 degrees of bending backward, and both crooked radian and position are equal, and all the other drop wire piece bodies are located the coplanar. The dropper is made of wear-resistant and smooth materials, so that the damage to warps is small in the weaving process, and the two side walls of the warp holes are bent in the same radian in opposite directions, so that the contact with the warps can be reduced, the yarn damage is reduced, the high-efficiency weaving of low-strength yarns or few sizing yarns is realized, the cost of the dropper is reduced, and the slurry pollution is reduced.

Description

Warp stop sheet for automatic warp stop of loom

Technical Field

The utility model relates to a warp stop motion piece for loom warp stop motion belongs to spinning machine technical field.

Background

During weaving, about 4000 times of reciprocating motion can be generated by the action of a heald frame in the process that warp yarns are from a warp beam to a cloth fell. In the process, the drop wire is used as a warp stop motion device, and the drop wire comprises an opening drop wire and a closing drop wire. The existing closed dropper is generally a thin sheet made of materials such as stainless steel, carbon steel and the like, has heavy weight and poor wear resistance, and damages the yarns in each weaving process. Reducing the weaving performance of the yarns and increasing the number of broken ends of the warp yarns. For example, chinese patent publication No. CN102864560A discloses a wear-resistant dropper, which is made by plating a wear-resistant layer on the dropper body and plating a chromium layer on the wear-resistant layer, so that the dropper has wear resistance, but the dropper needs to be plated 2 times during the production process, which is complicated in production and high in cost. And the plating layer loses the abrasion resistance effect with time, and the drop wire has no effect of reducing the abrasion of the yarn. For example, chinese patent publication No. CN103938348A discloses a warp stop sheet with scratch resistance and long service life, a groove is formed below the warp hole of the warp stop sheet, and the contact surface between the warp and the warp stop sheet is increased, so that the mutual unit friction is reduced, but the thickness of the warp stop sheet itself is increased, and the damage of the weight to the yarn in the weaving process is increased. The above patents are directed only to protecting the drop wires and do not address the problem of reducing the damage to the weavability of the yarns during weaving.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a warp stop sheet which can overcome the defects and has excellent working performance and is used for automatic warp stop of a loom. The technical scheme is as follows:

including the dropper body, dropper body upper end is equipped with rectangular slotted hole, and dropper body middle part is equipped with warp yarn hole, its characterized in that: the plane passing through the thickness of the drop wire body 1/2 is taken as a symmetry plane, one side wall of the warp hole is bent forwards by 0.5-1.5 degrees and the other side wall of the warp hole is bent backwards by 0.5-1 degrees along the longitudinal center line direction of the drop wire body, the radian and the position of the two bends are equal, and the rest drop wire bodies are positioned on the same plane.

The drop wire for automatic stop of warp broken of the loom has a drop wire body with the length of 16cm, the width of 6cm and the thickness of 0.2mm-0.4mm, and the drop wire body, the warp yarn hole and the long slotted hole share the center line.

The dropper for automatic warp stop of the loom has opaque dropper body.

Compared with the prior art, the utility model, its beneficial effect is:

1. the drop wire is made of wear-resistant and smooth materials, so that the damage to warp yarns is small in the weaving process, and the two side walls of the warp yarn hole are bent forwards and backwards in the same radian in opposite directions, so that the contact between the warp yarns and the drop wire can be reduced, and the damage to the yarns caused by the friction of the warp yarns and the drop wire is reduced.

2. The dropper is made of wear-resistant and smooth plastic materials, so that the high-efficiency weaving of low-strength yarns or few sizing yarns can be realized, the purposes of reducing cost and slurry pollution are achieved, and the green production is realized.

3. The cost of the dropper can be reduced due to the low manufacturing cost of the dropper material.
