Description

Dyeing machine

Technical Field

The invention relates to the technical field of dyeing machine equipment, in particular to a dyeing machine.

Background

The dyeing machine is used for dyeing cloth, and the structure of the dyeing machine comprises a cylinder body, a cloth lifting mechanism for driving cloth to be pushed, a nozzle mechanism for spraying and dyeing the cloth, and a filtering mechanism for recovering dyeing liquid. However, the existing dyeing machine mechanism has the following disadvantages:

1. the dyeing liquor is in the spray-dyeing circulation process because the gray cloth always drops the cotton wool, so the cotton wool is intercepted and filtered by the filter screen, and the problem that the nozzle mechanism is blocked to cause uneven dyeing of the cloth is solved. The filtering system mechanism of the traditional dyeing machine is generally arranged at the front end of a dye liquor outlet pipe of a circulating main pump, the filtering holes of a common filter screen are completely blocked by cotton wool in the dyeing process to influence the circulating effect of the dye liquor, but the dyeing cannot be stopped to clean the filtering mesh in the dyeing process, so that the traditional filter screen has to use a large filtering area to prevent the situation that the filter screen is completely blocked in the dyeing process, and a larger mounting area is occupied; and after dyeing is finished, the filter screen is taken out and cleaned, and then another grey cloth dyeing project is carried out, so that the operation is time-consuming and inconvenient.

2. When the rotating speed of the cloth lifting wheel of the cloth lifting mechanism is too high and is higher than the cloth carrying speed of the nozzle mechanism, the cloth is easy to wind on the cloth lifting wheel, so that the cloth dyeing cycle is stopped. The cloth needs to be unwound manually after shutdown, operation and maintenance are inconvenient, time is consumed, and the working efficiency is reduced.

3. The nozzle mechanism is used for enabling the cloth to smoothly and orderly circulate and uniformly spray the dye liquor onto the cloth. The cloth and the dye liquor are pushed by the dye liquor sprayed out of the nozzle, enter the cloth groove for dip dyeing after passing through the cloth guide pipe, and are lifted by the cloth placing and lifting wheel and pushed by the dye liquor sprayed and pressed by the nozzle, so that the cloth and the dye liquor can be subjected to multiple cycles to complete the cloth dyeing process. Generally, the dye liquor is pumped into the nozzle mechanism from the pump body, so that the dye liquor pressure is insufficient or uneven, uneven dyeing of cloth is caused, even uneven impact force on each part of the cloth causes uneven change of the structure of each part of the cloth, and the texture of the cloth is influenced.
