Automatic detector for yarn breakage of insulating yarns

Abstract

The invention relates to an automatic detector for the yarn breakage of insulating yarns. The automatic detector is characterized by comprising a mounting base, a sensor mounting plate, a detection substrate, a rotating shaft and a bearing seat, wherein the bearing seat is mounted at the upper part of the mounting substrate, the rotating shaft is mounted in the bearing seat, the detection substrate is fixedly mounted at one end, horizontally stretching out of the mounting base, of the rotating shaft, a yarn penetrating hole is formed in the upper part of the detection substrate, and a magnet is fixedly mounted at the lower part of the yarn penetrating hole; and the sensor mounting plate is mounted at the lower part of the mounting base, a Hall sensor is fixedly mounted on the sensor mounting plate, and the magnet on the detection substrate and the Hall sensor on the sensor mounting plate are triggered when the detection substrate turns downwards around the rotating shaft. The automaticdetector for the yarn breakage of the insulating yarns is simple in structure, scientific and reasonable in design, high in yarn breakage detection precision, low in manufacturing cost and easy to operate and maintain, the rate of defective woven goods can be decreased, and the labor intensity of workers can be alleviated.

Description

technical field [0001] The invention belongs to special auxiliary equipment for yarn braiding machines in the field of fiber insulated wire and cable processing equipment, and relates to an automatic detector for insulating yarn breakage. Background technique [0002] In the process of wire and cable processing, the application of special motor lead wires such as fiber insulated wires requires multiple fiber insulation filaments to be combined together, twisted and tensioned to form the required yarn bundle, and then the yarn bundle is passed through the fiber insulation braiding machine. Processed into fiber insulation sheath. Since the existing doubling and plying machines and fiber insulation yarn knitting machines do not have breakage detection stop devices; Unable to find out in time, the doubling machine and fiber insulation yarn knitting machine still continue to operate, resulting in frequent occurrence of unqualified products in the braid layer; a large amount of f...

AI Technical Summary

Problems solved by technology

When a long defective line segment is found, sometimes it is necessary to manually turn the machine in the opposite direction to make it return to the defective position. The efficiency of fault handling for defective braiding is low, which affects the production efficiency of insulation braiding

[0004] In the existing photoelectric detection type disconnection detection device, the position setting of the detection substrate and the photoelectric sensor is unreasonable, and the narrow surface of the detection substrate corresponds to the photoelectric sensor, which causes the signal acquisition signal of the photoelectric sensor to be inaccurate and prone to missing collection. Affect the normal work of the knitting machine
