Yarn breakage retracting device for facilitating broken end connecting

Abstract

The invention discloses a yarn breakage retracting device for facilitatingbroken end connecting, and relates to the technical field of spinning machinery. The device comprises a base, a fixed seat isfixedly connected to the surface of the base, a standing column is fixedly connected to the surface of the fixed seat, upper retracting devices are fixedly connected on both sides of the standing column,lower retracting devicesare fixedly connected on both sides of the fixed seat, the inner surfaces of the upper retracting device and the lower retracting device are fixedly connected with retracting motors, the ends of the output shafts of the retracting motorsare fixedly connected with rotating rods, a plurality of lanyards are fixedly connected to the circumferential side surfaces of the rotating rods, hooksare fixedly connected with the ends of the lanyards, and the inner surfaces of the upper retracting device and the lower retracting device are rotatably connected with a plurality of rolling rods. Through the cooperationof the upper retracting device and the lower retracting device, the length of a fold line inside the device is increased through the hooks, so that a broken end ofa yarn is retracted toward the device, the broken end of the yarn can be quickly found, and the device has the advantage of facilitating the yarn broken end connecting.

Description

technical field [0001] The invention relates to the technical field of spinning machinery, in particular to a broken yarn unwinding device which is beneficial to continuous splicing of broken ends. Background technique [0002] Spinning frame, a spinning machine that draws, twists, and winds semi-finished roving or sliver into spun bobbins during the spinning process. The output and quality of spun yarn are a comprehensive reflection of the pros and cons of each process in the spinning process. The production unit of the spinning machine is the spindle, and the production level of the spinning frame is often measured by the output per thousand spindle hours. The production scale of the spinning mill is expressed by the total number of spindles owned by the spinning frame. The yarn spun on each spindle will be broken due to various reasons, and the broken end rate is often expressed by the number of broken ends that occur in 1,000 spindle hours. The level of broken ends aff...

Problems solved by technology

[0003] The current spinning frame only has the function of yarn breakage alarm, and does not check the specific breakage of the yarn, so that the workshop personnel cannot continue to connect the broken end of the yarn immediately after the machine breaks. Existing patent There is a quick search for the broken end of the first yarn through the airflow, but this method will make the yarn swing freely, affect the normal winding of other normal spindles, and is not conducive to the production of the workshop, so it is suitable for fast yarn search for spinning frames The device for thread breaking is a technical problem that those skilled in the art need to solve
