Slide way threading device

Abstract

The invention provides a slide way threading device. The slide way threading device comprises a slide way, a slide rod and a line-connecting seat, wherein the slide rod is assembled in a slide groove in the upper portion of the slide way, and a U-shaped horizontally-stretching line-feeding block is connected to the end portion of the slide rod; a horizontal groove is machined in the side position dead against the slide rod, of the line-connecting seat, line-stopping blocks vertically jacked by springs are assembled at the upper end and the lower end of the horizontal groove respectively, and the upper and lower jacked end portions of the line-stopping blocks are arc-shaped; a wrap to be weaved is divided into an upper group and a lower group, and penetrates through between the slide way and the line-connecting seat to form a staggering port. According to the device, a weft penetrates through the staggering port formed by the wrap by virtue of the slide of the slide rod, and threading is carried out without the need of using a shuttle; meanwhile, the slide of the slide rod is always carried out at one side parallel to the wrap, and the weft threading process can be carried out only by one hand, thus the labour intensity is lower, and the working efficiency is higher.

Description

technical field [0001] The invention relates to the technical field of textile machinery, in particular to a slideway threading device. Background technique [0002] The fabric is woven by interlacing warp and weft. The traditional loom adopts a manual structure to pull the warp side by side, and uses the heald frame structure to divide all the warp into two parts at intervals. The two warp on the heald frame Part of the interlaced sliding opening is formed, and then the weft thread is passed through the intersecting opening position of the upper and lower warp threads through the shuttle, and the shuttle carries the weft thread through the intersecting opening of the warp thread once, and the two heald frames each carry half of the warp thread to complete one up and down A staggered movement so that the weft threads are woven into the fabric at intervals. However, the current shuttle can only carry one weft thread at a time during the threading process. If two weft threads...

AI Technical Summary

Problems solved by technology

However, the current shuttle can only carry one weft thread at a time during the threading process. If two weft threads are used, the resistance during the sliding process of the shuttle will be greatly increased, making it difficult to slide. At the same time, the shuttle must be thrown back and forth at both ends of the warp thread The action passes the shuttle along with the weft thread

In the process of throwing the shuttle, it is necessary to use both hands to exchange and throw constantly, the labor intensity is higher, and the work is more tiring
