Broken yarn protection system of warp knitting machine

Abstract

The invention provides a broken yarn protection system of a warp knitting machine, and belongs to the technical field of spinning. The broken yarn protection system of the warp knitting machine solves the problems that yarn in an existing warp knitting machine is easy to break, and therefore machine faults can easily happen in a following mode. According to the broken yarn protection system of the warp knitting machine, the warp knitting machine comprises a machine frame and a yarn-feeding rolling barrel arranged on the machine frame, and the yarn-feeding rolling barrel is driven to rotate by a drive motor. The broken yarn protection system comprises an air outlet pipe, an infrared emitter and an infrared receiver, wherein the air outlet pipe is fixed to the machine frame and is parallel to the yarn-feeding rolling barrel, the infrared emitter is fixed to one end of the machine frame, the infrared receiver is fixed to the other end of the machine frame, the infrared emitter faces the infrared receiver, an inducing straight line is located on one side of yarn, the air outlet pipe is located on the other corresponding side of the yarn, and a plurality of air outlet holes facing the yarn are formed in the pipe body of the air outlet pipe. According to the broken yarn protection system of the warp knitting machine, when yarn is broken in the operating process, the drive motor can be automatically controlled to stop working so as to remind working personnel to replace the yarn, and accordingly machine faults are avoided.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a warp knitting machine, in particular to a thread breaking protection system of the warp knitting machine. Background technique [0002] The warp knitting machine is mainly composed of a knitting mechanism, a bar traverse mechanism, a let-off mechanism, a pulling and coiling mechanism and a transmission mechanism. The warp knitting machine has wide adaptability to raw materials and fabric varieties, and the machine productivity is high, so it develops rapidly. [0003] ①The knitting mechanism includes a needle bed, a bar, a sinker bed and a pressing plate, and is generally driven by a cam or an eccentric connecting rod. [0004] ②The cross-moving mechanism of the bar enables the bar to move horizontally according to the requirements of the knitted fabric during the loop forming process, and puts the warp yarn on the needle so as to weave a knitted fabric with a certain structure...

AI Technical Summary

Problems solved by technology

However, at present, whether the yarn is broken or not is all observed by the naked eye of the operator, so that the drive motor is turned off to stop working so that the yarn can be replaced; work, it will cause the warp knitting machine to break down, so when the yarn is broken, it is necessary to replace the broken yarn in time, so that the warp knitting machine can continue to work

Moreover, using manual observation to turn off the drive motor and replace the yarn is not only inefficient and heavy workload, but also unfavorable for the continuous work of the operator
