Overflow rotation breaking nozzle for dyeing machine

Abstract

The invention discloses an overflow rotation breaking nozzle for a dyeing machine. The overflow rotation breaking nozzle comprises an upper nozzle, a lower nozzle and a nozzle shell. A liquid inlet pipe is arranged on one side of the nozzle shell, a flange is fixed in the nozzle shell, the lower nozzle is fixedly connected to the outer side of the upper nozzle, the top of the upper nozzle is fixed to the upper face of the flange, and the upper nozzle and the lower nozzle are both cavity sections with polygonal cross sections. An annular liquid spraying opening with the polygonal cross section is formed between the outer side face of the upper nozzle and the inner side face of the lower nozzle, and when sprayed liquid passes through the annular liquid spraying opening with the polygonal cross section, the rotation phenomenon does not exist, and rotation is effectively broken. According to the overflow rotation breaking nozzle for the dyeing machine, the problems of blockage of a feeding port and non-uniform coloring caused by fabric winding due to rotation of dye liquid are solved, stable and reliable work of the nozzle can be ensured, and the fabric can be efficiently and uniformly colored.

Description

technical field [0001] The invention belongs to the technical field of dyeing machines, in particular to an overflow breaking nozzle for a dyeing machine. Background technique [0002] The overflow breaker dyeing machine uses the principle of Venturi, and the dye liquid conveyed by the pump body enters the Venturi nozzle to drive the fabric to move and dye it. During the dyeing process, the dye solution is accelerated and sprayed out through the nozzle to dye the fabric, and the dyeing process is completed. [0003] The nozzle of the overflow breaker dyeing machine is a device used to make the cloth circulate smoothly and orderly and spray the dyeing liquid evenly on the cloth. At present, the nozzles of traditional dyeing machines are mostly circular cross-section cloth passages and liquid spray ports. In actual production, because the dye liquid rotates in the liquid spray ports, the fabric will be entangled and knotted when it drives the movement, resulting in low work e...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an overflow breaking nozzle for a dyeing machine to solve the problems in the prior art that the dyeing machine rotates when the dye solution is sprayed, causing the fabric to become knotted and entangled, the fabric to be dyed unevenly or the cloth feeding channel of the dyeing machine to be stuck. question
