Fabric dyeing machine nozzle structure

Abstract

The invention provides a nozzle structure of a cloth dyeing machine. The structure comprises a front pipe, a back pipe and a jet-flow gap formed between the front pipe and the back pipe. The back pipeis connected to the front pipe. Two ends of the back pipe are respectively a back connecting end and an outlet end. The back connecting end is adjacent to the front pipe. The back pipe contains a back cloth dyeing segment and a slow flow segment, which are connected with each other. The back cloth dyeing segment is adjacent to the back connecting end. The slow flow segment is adjacent to the outlet end. The pipe diameter of the slow flow segment becomes shrinking from the joint between the slow flow segment and the back cloth dyeing segment to the outlet end. By adoption of the slow flow segment with the shrinking pipe diameter, dyeing liquid flow more slowly when passing the slow flow segment and contacts the cloth more longer. Additionally, jet flows of the dyeing liquid collide with the pipe wall of the slow flow segment. Multiple splattering is generated between the pipe wall and the cloth. Accordingly, more uniform dyeing is achieved without increasing speed of jet flows of the dyeing liquid and meanwhile the cloth is prevented against damage by avoiding water cutting.

Description

technical field [0001] The invention relates to a dye nozzle for a cloth dyeing machine. Background technique [0002] The nozzles of the cloth dyeing machine are generally in the shape of a tube for the cloth to pass through the inside and be dyed while passing through; while the tubular dyeing machine nozzle is divided into a front tube and a rear tube connected to each other, and there is a shaped gap between the front tube and the rear tube. The gap, the dye liquid is sprayed into the pipe through the gap to dye the cloth, and the size of the gap is related to the speed of the jet flow of the dye liquid. However, in the process of dyeing cloth, if the jet flow speed of the dye solution is too fast, it will cause a water knife phenomenon, which will damage the surface of the cloth; on the contrary, if the jet flow speed of the dye solution is too slow, the dye solution will not penetrate easily Into the inner layer of the cloth, and then cause the situation of uneven dye...

AI Technical Summary

Problems solved by technology

However, in the process of dyeing cloth, if the jet flow speed of the dye solution is too fast, it will cause a water knife phenomenon, which will damage the surface of the cloth; on the contrary, if the jet flow speed of the dye solution is too slow, the dye solution will not penetrate easily into the inner layer of the cloth, resulting in uneven dyeing; therefore, how to solve the above problems will be an important issue

[0003] In addition, around the gap between the front pipe and the rear pipe, there are likely to be residues formed by the solidification of the cloth cotton wool and the dye liquor, and because the gap between the front pipe and the rear pipe of the cloth dyeing machine nozzle in the prior art The distance is fixed, that is to say, the gap between the front tube and the rear tube cannot be reset, which will cause the problem of inconvenient cleaning of the gap, and when there is too much residue It will block the gap and even speed up the jet flow of the dye liquor, thereby causing the aforementioned water jet phenomenon. Therefore, the nozzles of the cloth dyeing machines in the prior art really need to be improved.
