[0002] With the rapid development of the economy and the increasing improvement of the scientific and technological level, dyeing equipment is also developing rapidly, putting forward higher requirements for dyeing quality and efficiency. During the dyeing process of a dyeing machine, one of the steps is to introduce the dye liquor into the dyeing machine for subsequent fabric dyeing. However, currently, when the dye liquor enters the supply channel of the dyeing machine through the supply pipeline, swirl of the dye liquor occurs. The swirling dye liquor reaches the spray holes, resulting in uneven spraying of the ejected dye liquor, which further affects the quality of the fabric dyed by the dyeing machine. Summary of the Utility Model

[0026] Please refer to Figures 1 to 4 As shown, an anti - swirl nozzle structure of a dyeing machine provided by an embodiment of the present application includes a nozzle assembly 10 and an outer cylinder 20, wherein:

[0027] The outer cylinder 20 is installed around the nozzle assembly 10. An annular liquid - supply channel 30 is formed between the outer cylinder 20 and the nozzle assembly 10. A liquid - supply port 21 communicating with the liquid - supply channel 30 is opened on the outer cylinder 20;

[0028] The nozzle assembly 10 has a cloth - dyeing channel 40 for the cloth to pass through. An annular liquid - spraying hole 22 communicating with the cloth - dyeing channel 40 is provided on the nozzle assembly 10. The dye liquor is introduced into the liquid - supply channel 30 through the liquid - supply port 21 and then sprayed onto the cloth in the cloth - dyeing channel 40 through the liquid - spraying hole 22;

[0029] A plurality of flow - dividing plates 23 are arranged at intervals along the circumferential direction on the nozzle assembly 10. The plurality of flow - dividing plates 23 are configured to divide the dye liquor entering the liquid - spraying hole 22 in the liquid - supply channel 30.

[0030] By arranging a plurality of diverter plates 23 at intervals along the circumferential direction on the nozzle assembly 10, the dye liquid near the nozzle assembly 10 is isolated, which not only successfully avoids the vortex flow of the dye liquid near the nozzle assembly 10, but also has a simple structure, which facilitates the uniform spraying of the dye liquid onto the dyed cloth, thereby improving the dyeing quality of the dyeing machine.

[0031] In one embodiment, the nozzle assembly 10 includes a first nozzle 11 and a second nozzle 12 which are coaxially arranged, the second nozzle 12 having a first channel 120 therein, the first nozzle 11 having a second channel 110 therein, the first nozzle 11 being mounted on the second nozzle 12 so that the first channel and the second channel form a dyeing channel 40, and a liquid spraying hole 22 is formed between the top of the second nozzle 12 and the bottom of the first nozzle 11.

[0032] Through the cooperation of the first channel and the second channel, not only is a dyeing channel 40 for transporting cloth in the nozzle assembly 10 formed, but also the structure is compact and space is saved; through the cooperation of the first nozzle 11 and the second nozzle 12, the spray hole 22 is connected to the dyeing channel 40, which is convenient for the dye liquid to be directly sprayed onto the cloth in the dyeing channel, saving time and improving the dyeing efficiency of the dyeing machine.

[0033] In one embodiment, the first ends of the plurality of diverter plates 23 are fixed on the first nozzle 11 , and the second ends of the plurality of diverter plates 23 extend across the liquid spraying hole 22 toward the second nozzle 12 .

[0034] By extending the second end of the diverter plate 23 beyond the spray hole 22 toward the second nozzle 12, the blocking area for the swirling dye liquid is increased, which not only effectively blocks the dye liquid near the spray hole 22 to avoid swirling flow, but also has a simple structure and saves costs.

[0035] In one embodiment, a limiting portion 230 is provided on each diverter plate 23 , and after the first nozzle 11 is mounted on the second nozzle 12 , the top of the second nozzle 12 abuts against the limiting portion 230 .

[0036] By providing a limiting portion 230 on the manifold 23 and arranging the limiting portion 230 on the top of the second nozzle 12 fitted with the first nozzle 11 , the accuracy of installation of the second nozzle 12 is ensured, and the uniformity and consistency of the liquid spraying from the liquid spraying hole 22 are improved.

[0037] In one embodiment, the limiting portion 230 includes a limiting step opened on the inner side of the second end of each diverter plate 23, and the limiting step includes a horizontal limiting surface 231 and a vertical limiting surface 232. After the first nozzle 11 is mounted on the second nozzle 12, the top of the second nozzle 12 abuts against the horizontal limiting surface 231, and the vertical limiting surface 232 is configured to limit the outer side of the top of the second nozzle 12.

[0038] Through the cooperation of the horizontal limiting surface 231 and the vertical limiting surface 232, the concentricity of the installation of the coaxially arranged first nozzle 11 and second nozzle 12 is ensured.

[0039] In one embodiment, the cloth inlet of the first nozzle 11 and the second nozzle 12 is in a conical shape with an outer diameter decreasing from outside to inside, and the cloth outlet of the first nozzle 11 is sleeved on the cloth inlet of the second nozzle 12.

[0040] By setting the cloth inlet of the first nozzle 11 to be in a conical shape with an outer diameter decreasing from outside to inside, the area of the cloth inlet of the first nozzle 11 is increased, facilitating the entry of the fabric; by setting the cloth inlet of the second nozzle 12 to be in a conical shape with an outer diameter decreasing from outside to inside, it facilitates the sleeving of the first nozzle 11 and the second nozzle 12, and at the same time facilitates the cloth outlet of the first nozzle 11 to lead into the cloth inlet of the second nozzle 12.

[0041] In one embodiment, the bottom of the liquid supply channel 30 is provided with a flange 31, the cloth outlet of the second nozzle 12 passes through the flange 31, and the flange 31 is configured to connect the cloth outlet of the second nozzle 12 with an external dyeing cloth pipeline.

[0042] By setting the bottom of the liquid supply channel 30 as the flange 31, on the one hand, it provides a passage space for the cloth outlet of the second nozzle 12, and on the other hand, it connects the external cloth guiding channel, facilitating the transportation of the fabric.

[0043] In one embodiment, a sealing ring 310 is provided on the flange 31, and the sealing ring 310 is configured to seal a plurality of interfaces 32 on the flange 31.

[0044] By providing the sealing ring 310 on the interface 32 of the flange 31, the leakage of the dyeing liquid in the liquid supply channel 30 is avoided, and at the same time, the safety of other mechanisms in the dyeing machine is protected.
