A cloth printing and dyeing device capable of intermittently supplying dye

Abstract

The invention discloses a cloth printing and dyeing device capable of intermittently supplying dyes, which comprises a dyeing chamber, which is provided with a partition board, and the dyeing chamber is divided into an upper dyeing chamber and a lower dyeing chamber by the partition board; a dipping roller is arranged in the dyeing chamber The driving part is used to drive the dyeing roller to rotate; the feeding part is used to intermittently feed materials to the upper dyeing chamber; the liquid circulation part is used to drive the liquid to circulate between the upper dyeing chamber and the lower dyeing chamber. The present invention intermittently adds dyes to the dyeing room through the feeding part, so that the dye in the dyeing solution can be replenished in time, the color difference of the dyed cloth is small, and the dyeing effect is good; secondly, since the dyeing room is divided into upper and lower two There are three chambers, and it is equipped with liquid circulation components, so that the dye added to the dyeing chamber can be fully mixed with the dye solution during the flow process, which improves the uniformity of cloth dyeing.

Description

technical field [0001] The invention belongs to the technical field of cloth printing and dyeing, in particular to a cloth printing and dyeing device capable of intermittently supplying dyes. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method for fabrics, usually including pretreatment, printing, dyeing, finishing, washing and other steps; the existing dyeing equipment usually uses dyeing rollers to drive the fabric from the dyeing After passing through the dye solution in the pool, the dyeing of the cloth is realized. For example, Chinese patent CN204939851U discloses "A Device for Dyeing Cloth", which includes a dyeing tank, a dyeing roller, a lead-in roller and a lead-out roller, and part or all of the dyeing rollers are placed in the dyeing tank. , to achieve coloring. However, under this structure, the fabric is continuously and differently conveyed forward, and the dye will be taken away by the fabric, result...

AI Technical Summary

Problems solved by technology

However, under this structure, the fabric is continuously and differently conveyed forward, and the dye will be taken away by the fabric, resulting in a decrease in the concentration of the dye solution in the dyeing pool. Usually, after a period of time, the control equipment needs to be stopped to add the dye, and the dye and The dyeing solution is mixed evenly before restarting the equipment, which affects the work efficiency, and it is often impossible to ensure that the concentration of the dyeing solution is consistent with the initial concentration, which may easily cause color difference in fabric dyeing
