Tension measurement and control device of beam dyeing machine

Abstract

The invention discloses a tension measuring and controlling device of a jig dyeing machine, which comprises a casing used for containing dye solution, a first cloth roller and a second cloth roller that is positioned above the first cloth roller; wherein, the first cloth roller and the second cloth roller are respectively connected with a variable-frequency motor that can control the rotating speed and the torque; the device also comprises a first lower track roller and a second lower track roller which are positioned inside the dye solution. The device is characterized by further comprising a force-measuring roller arranged between the first lower track roller and the second lower track roller, as well as a first hydraulic cylinder and a second hydraulic cylinder that are respectively arranged outside the casing; wherein, the two ends of a roll shaft of the force-measuring roller respectively act on the ends of hydraulic rods of the first hydraulic cylinder and the second hydraulic cylinder; the singles of a first pressure sensor used for measuring the pressure of the first hydraulic cylinder and a second pressure sensor used for measuring the pressure of the second hydraulic cylinder are transmitted into a control computer which can control the running of the variable-frequency motor that is respectively connected with the first cloth roller and the second cloth roller. The tension measuring and controlling device can realize the aim of immediately measuring and controlling the tension of cloth when the jig dyeing machine dyes.

Description

technical field [0001] The invention relates to a tension measurement and control device for a jigger, which belongs to the field of textile printing and dyeing. Background technique [0002] The textile printing and dyeing industry is an industry with high energy consumption and high pollution. Therefore, the development of dyeing machines with low energy consumption and low emissions is the goal of the printing and dyeing machinery manufacturing industry. Generally, the dye bath ratio of the overflow jet dyeing machine is about 1:20, that is, 1 kg of cloth (fabric) needs to be dyed with 20 kg of dye solution (most of which is water, and water accounts for about 99.98% of the dye solution). The dyeing bath ratio of the dyeing jigger is only about 1:3, and the lowest can be below 1:2. Compared with the overflow jet dyeing machine, it can save a lot of energy, mainly coal, electricity, water consumption, and dyeing sewage at the same time The emission is only about one tenth...

AI Technical Summary

Problems solved by technology

But its disadvantage is that there is head-to-tail color difference in the dyeing of the jigger, which is related to the unsteady tension of the cloth during dyeing. When the tension is high in the same dyeing, the amount of dyed cloth is less, the dyeing color is light, and the tension is small. The amount of dyed cloth is large, the color is deep, and the change of tension causes the color difference between the head and the tail of the same dyeing

At present, there is no reliable tension measurement and control device to measure the tension of the fabric when the jigger is dyeing
