Wheel disc type false twist compact spinning device with broken-end breakpoint control function

Abstract

The invention relates to a wheel disc type false twist compact spinning device with a broken-end breakpoint control function. Each spindle position of the wheel disc type false twist compact spinningdevice with the broken-end breakpoint control function comprises a friction wheel, a transmission wheel, a base, a hairiness suppressor and a broken-end breakpoint control mechanism. In the device, the friction wheels and the transmission wheels are mounted on the bases, the transmission wheels realize transmission of the friction wheels through gears or shafts, the transmission wheels are drivenby transmission belts, the edges of the friction wheels are in contact with fiber strands, the fiber strands are driven to rotate back through friction to realize false twist, and the broken-end breakpoint control mechanism controls the hairiness suppressor; when a broken-end signal is received, the broken-end breakpoint control mechanism rotates the hairiness suppressor to cause a plane in contact with the fiber strands to deflect relative to a normal spinning position, so that the wrapping angles between the fiber strands and the edges of the friction wheels are reduced, twist of the fiber strands is stopped or the transmission of twist towards a front roller jaw is blocked, and therefore the fiber strands are broken at the front roller jaw.

Description

technical field [0001] The invention belongs to the technical field of ring spinning, and in particular relates to a wheel-type 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 Ring Spinning" , ZL 201...

[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. After the hair is generated, it is necessary to remove the fiber strands in time to avoid winding the rollers. If the suction pipes are installed on the jaws of the two rollers, the energy consumption will be increased.
