Warp beam yarn leasing device and leasing method thereof

Abstract

The invention belongs to the field of textile machinery and discloses a warp beam yarn leasing device and a leasing method thereof. The warp beam yarn leasing device comprises a yarn pressing device and a straight reed carriage which are arranged front to back, and a straight reed is arranged on the straight reed carriage. The yarn pressing device comprises a mounting support, yarn pressing lifting devices, yarn pressing strips and yarn pressing strip connectors. The yarn pressing lifting devices in more than two pairs are fixed to two sides of the mounting support, and two ends of each yarn pressing strip are connected to the corresponding pair of yarn pressing lifting devices through the corresponding yarn pressing strip connectors. The warp beam yarn leasing device and the leasing method thereof have advantages that by adoption of the yarn pressing strips for replacement of traditional iron rods, operation time is saved; one person can control ascending and descending of the yarn pressing strips through a switch to realize yarn pressing, two-person operation is avoided, operator quantity is decreased, and one person can complete yarn pressing and leasing operations in ten minutes finally, so that production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the field of textile machinery, in particular to a warp beam yarn splitting device and a splitting method thereof. Background technique [0002] In the field of textiles, weaving needs to go through many processes, including warp raw materials, warping, sizing, sub-twisting, drawing-in, and machine weaving. The two warp yarns are separated to complete the sub-twisting. [0003] At present, the method of warp beam threading and sub-twisting is mainly to use a sub-twisting machine to perform sub-twisting, which takes a lot of time to operate, and is prone to parallel twisting problems, which cannot be completely solved. For example, the utility model patent with the notification number CN204039609U discloses a warp yarn splitting device, which utilizes the gravity of the split reed and the pulling force of the reed teeth to realize the layering of odd and even warp yarns, but it still has a large workload and is prone to problem...

AI Technical Summary

Problems solved by technology

[0007] In order to overcome the problems of high labor intensity in the prior art, requiring two people to work at the same time, taking a long time, and low production efficiency, the present invention provides a warp beam yarn The splitting device can reduce the number of operators, reduce the working time, reduce the working intensity, and improve the working efficiency. One person can complete the threading and splitting operation in ten minutes.
