Tail yarn reserving mechanism for blank pipe of rotor spinning machine

Abstract

The invention provides a tail yarn reserving mechanism for a blank pipe of a rotor spinning machine. The mechanism comprises an air suction pipe, a yarn forking plate, a yarn supporting rod, a yarn guide nozzle device, a paper pipe, a tooth-shaped top disc and a shear blade device. The tail yarn reserving mechanism has the advantages that the tail yarn reserving mechanism is adopted for replacingan existing manual operation mode of hooking the reserved tail yarn through fingers, the situation is avoided that the fingers are cut to be injured through the yarn which moves quickly, and the mechanism is safer to operate and high in practicability. According to the tail yarn reserving mechanism, spinning does not need to be stopped during doffing, the tail yarn is reserved on a bobbin, and theproduction efficiency of the next process is improved. The tail yarn reserving mechanism is simple in structure and convenient to use, maintain and care.

Description

technical field [0001] The invention relates to the technical field of spinning machinery, in particular to a mechanism for reserving a tail yarn in an empty tube of a rotor spinning machine. Background technique [0002] Rotor spinning machine is a high-speed, high-efficiency, automatic waste-discharging new type of free-end spinning machine, which can directly spin various short fibers and viscose fibers from carded sliver into single spun yarn. However, when the existing rotor spinning machine is about to interrupt the yarn, it generally needs to carry out the operation of artificial fingers to catch the tail yarn, but this operation is easy to cut the fingers by the fast moving yarn, the operation is unsafe, leaving Yarn efficiency is low, although existing technology is also provided with reserved tail yarn mechanism in the spinning machine, but existing reserved tail yarn mechanism has complex structure, inconvenient use, inconvenient repair, maintenance, is difficult ...

AI Technical Summary

Problems solved by technology

However, when the existing rotor spinning machine is about to interrupt the yarn, it generally needs to carry out the operation of artificial fingers to catch the tail yarn, but this operation is easy to cut the fingers by the fast moving yarn, the operation is unsafe, leaving The yarn efficiency is low. Although the existing technology also has a reserved tail yarn mechanism in the spinning machine, the existing reserved tail yarn mechanism has a complicated structure, is inconvenient to use, is not easy to repair and maintain, and is difficult to be widely promoted.
