Tension measuring and control device for jig dyeing machine

一种卷染机张力测量与控制装置

Abstract

本实用新型公开了一种卷染机张力测量与控制装置,包括用于盛装染液的机壳,第一卷布辊和第二卷布辊位于染液上方,并分别与一个可控制其转速和转矩的变频电机相连,第一下道辊和第二下道辊位于染液内部,其特征在于:还包括一个位于第一下道辊和第二下道辊之间的测力辊,在所述测力辊的两侧、机壳的外部分别设置有第一测力支架和第二测力支架,所述测力辊的辊轴两端分别作用在两个测力支架上,用于测量第一测力支架压力的第一电子压敏传感器和用于测量第二测力支架压力的第二电子压敏传感器的信号送入可控制分别与第一卷布辊和第二卷布辊相连的变频电机的运转的控制计算机。本实用新型能够实现即时对卷染机染色时布料的张力进行测量与控制的目的。
The utility model discloses a tension measuring and control device for a jig dyeing machine, which comprises a casing for holding a dye solution. A first cloth roller and a second cloth roller are positioned above the dye solution and respectively connected with a variable-frequency motor capable of controlling the rotating speed and the torque thereof; and a first lower track roller and a second lower track roller are positioned inside the dye solution. The tension measuring and control device is characterized in that the device further comprises a force measuring roller poisoned between the first lower track roller and the second track roller; a first force measuring bracket and a second force measuring bracket are respectively arranged on the two sides of the force measuring roller and outside the casing; the two ends of a roll shaft of the force measuring roller respectively act on the two force measuring brackets; and signals of a first electronic pressure-sensitive sensor used for measuring the pressure of the first force measuring bracket and of a second electronic pressure-sensitive sensor used for measuring the pressure of the second force measuring bracket are transmitted to a control computer capable of controlling the operation of the variable-frequency motor respectively connected with the first cloth roller and the second cloth roller. The utility model can achieve the purpose of measuring and controlling tension of cloth immediately during the dyeing of the jig dyeing machine.
