Flat cable type coil cloth leftover detection device

Abstract

The invention discloses a flat cable type coil cloth leftover detection device. The flat cable type coil cloth leftover detection device comprises a magnetic ball, a detection circuit and an induction coil, wherein the magnetic ball is fixed on to-be-dyed cloth, the induction coil is arranged on the outer wall of a cloth guiding pipe of a cloth dyeing machine and is connected with the detection circuit; and when the magnetic ball moves in the cloth guiding pipe of the cloth dyeing machine and passes through the induction coil, the detection circuit detects a signal, processes the signal and output the counting signal of a fixed phase width. According to the flat cable type coil cloth leftover detection device, the motion parameters of cloth in a dyeing cylinder can be simply, rapidly, accurately and efficiently measured, so that the detection rate of cloth leftover is greatly increased.

Description

technical field [0001] The invention belongs to the field of automatic control of textile printing and dyeing, and in particular relates to a wire arrangement type coil cloth head detection device. Background technique [0002] In the traditional dyeing process, the cloth dyeing workers observe the operation of the cloth and the degree of dyeing at the entrance and exit of the dyeing machine. The dyeing time of the cloth in the dyeing machine is determined by the experience of the workers, which results in uneven dyeing of the cloth. The cloth is of poor quality. [0003] Chinese patent 201320589221.8 discloses a cloth head detector and a dyeing machine using it. Most cloth head detectors on the market use this structure, and its detection accuracy is determined by the distance between the magnetic beads and the detector. The farther the distance is, the farther the accuracy will be. When the magnetic beads swing together with the cloth in the cloth guide tube, the detectio...

[0003] Chinese patent 201320589221.8 discloses a cloth head detector and a dyeing machine using it. Most cloth head detectors on the market use this structure, and its detection accuracy is determined by the distance between the magnetic beads and the detector. The farther the distance is, the farther the accuracy will be. When the magnetic beads swing together with the cloth in the cloth guide tube, the detection distance is sometimes close and sometimes far, the detection results are easily disturbed, and the detection system is unstable
