Single-spindle double-wheel belt combined structure false-twisting compact spinning device with broken end and breakpoint control

Abstract

A single-spindle double-wheel belt combined structure false-twisting compact spinning device with broken end and breakpoint control comprises a friction belt, a driving wheel, a driven wheel, a transmission wheel, a transmission shaft, a base, a hairiness suppressor and a broken end and breakpoint control mechanism; In each spindle position, the driving wheel and the driven wheel position the friction belt to circularly rotate in a back-and-forth track, a straight section on one side is a friction side where the friction belt contacts a fiber strand, the friction belt of the straight section on the friction side can be mounted in parallel to an outgoing roller jaw and is 1-10 mm away from the outer circular surfaces of upper and lower outgoing rollers, the broken end and breakpoint controlmechanism is used for controlling the hairiness suppressor, the broken end and breakpoint control mechanism rotates the hairiness suppressor when a broken end signal is received, the plane in contactwith the fiber strand is deflected relative to a normal spinning position, the path of the fiber strand is changed to block the twist from passing to a front roller jaw, and the fiber strand is interrupted at the front roller jaw.

Description

technical field [0001] The invention belongs to the technical field of ring spinning, and relates to a single-spindle double-pulley combined structure false-twisting compact spinning device with end-break point control. Background technique [0002] Long hairiness of the yarn is usually a harmful defect of the yarn. In order to eliminate the hairiness of the yarn, the current actual production basically uses air flow to gather the fiber bundles before twisting. In the above two types of methods, the airflow method will generate greater energy consumption, and the mechanical method will cause friction; twisting will cause fiber bundles, the false twist technology in the twisting method, and the low twist spinning technology in the ring spindle People have done a lot of research, typical examples are: "Clamping False Twisting Device" proposed in ZL200710089867.9, and the loop dragon belt proposed in ZL 201310091686.5 "Method and Device for Applying False Twist to Yarn Before R...

[0002] Long hairiness of the yarn is usually a harmful defect of the yarn. In order to eliminate the hairiness of the yarn, the current actual production basically uses air flow to gather the fiber bundles before twisting. In the above two types of methods, the airflow method will generate greater energy consumption, and the mechanical method will cause friction; twisting will cause fiber bundles, the false twist technology in the twisting method, and the low twist spinning technology in the ring spindle People have done a lot of research, typical examples are: "Clamping False Twisting Device" proposed in ZL200710089867.9, and the loop dragon belt proposed in ZL 201310091686.5 "Method and Device for Applying False Twist to Yarn Before Ring Spinning" , ZL 201080056636.8 "Ring Spinning Machine with False Twist Device" proposed friction wheels of various structures. These mechanisms are all aimed at the false twist process requirements of low twist spinning. The goal is different, the process is different, the yarn forming process is different, and the mechanism settings are different. The friction type false twist compact spinning proposed by me in the early stage contains two pairs of rollers, the front roller and the lead-out roller. Both roller jaws are equipped with suction pipes, which will increase energy consumption, so it is necessary to develop and research a false twist compacting device that meets false twist compact spinning
