[0027] Please refer to Figures 1 to 5 as shown, an adjustable nozzle structure provided by an embodiment of the present application includes a nozzle assembly 10 and an outer cylinder 20, wherein:

[0028] The outer cylinder 20 is installed on the periphery of the nozzle assembly 10, and an annular liquid supply channel 30 is formed between the outer cylinder 20 and the nozzle assembly 10. A liquid supply port 31 communicating with the liquid supply channel 30 is opened on the outer cylinder 20;

[0029] The nozzle assembly 10 has a cloth dyeing channel 11 for the cloth to pass through. An annular liquid spraying hole (not shown in the figure) communicating with the cloth dyeing channel 11 is provided on the nozzle assembly 10. The size of the liquid spraying hole changes according to the change of the nozzle assembly 10. The dyeing liquid is introduced into the liquid supply channel 30 through the liquid supply port 31 and then sprayed onto the cloth in the cloth dyeing channel 11 through the liquid spraying hole.

[0030] By adjusting the nozzle assembly 10 to change the size of the liquid spraying holes, the amount of the dye liquor sprayed is adjusted, which not only meets the requirements of different fabrics for different amounts of dye liquor, improves the equipment compatibility, but also has a simple structure and is convenient to operate.

[0031] In one embodiment, the nozzle assembly 10 includes a first nozzle 12, a second nozzle 13 and a first pipe 14 which are coaxially arranged. The second nozzle 13 is adjustably sleeved on the first nozzle 12. The first nozzle 12 has a first channel 120 therein, and the first pipe 14 has a second channel therein. The outlet of the first channel 120 is sleeved in the second channel so that the first channel 120 and the second channel form a fabric dyeing channel 11.

[0032] Through the cooperation of the first channel 120 and the second channel, a fabric dyeing channel 11 convenient for the fabric to pass through is formed. It not only has a simple structure and is convenient to operate, but also the fabric dyeing channel 11 is located in the middle of the nozzle assembly 10, saving space.

[0033] In one embodiment, a first thread 121 is arranged on the outer wall of the first nozzle 12, and a second thread is arranged at the position where the second nozzle 13 contacts the outer wall of the first nozzle 12. The first thread 121 and the second thread are in staggered contact, and an adjustable liquid spraying hole is formed at the bottoms of the first nozzle 12 and the second nozzle 13.

[0034] Through the cooperation of the first thread 121 and the second thread, not only the movement of the second nozzle 13 along the outer wall of the first nozzle 12 is realized, and then the size of the liquid spraying hole is changed, improving the equipment compatibility, but also the structure is simple, the operation is convenient, and the fabric dyeing efficiency of the dyeing machine is improved.

[0035] In one embodiment, a plurality of flow dividing plates 15 are arranged on the nozzle assembly 10 in the circumferential direction. The plurality of flow dividing plates 15 are configured to divide the dye liquor entering near the liquid spraying holes in the liquid supply channel 30.

[0036] By arranging the flow dividing plates 15 on the circumference of the nozzle assembly 10, the dye liquor which inevitably generates swirl when passing through the liquid supply port 31 into the liquid supply channel 30 is blocked by the flow dividing plates 15 when reaching near the liquid spraying holes. This not only effectively prevents the swirl of the dye liquor, makes the dye liquor evenly sprayed into the fabric dyeing channel 11, but also has a simple structure and saves costs.

[0037] In one embodiment, a plurality of first notches 130 are formed on the side surface of the second nozzle 13. The first notches 130 are configured to guide the dye liquor in the liquid supply channel into the space between the first nozzle 12 and the second nozzle 13 so as to be sprayed out from the liquid spraying holes.

[0038] By forming a plurality of first notches 130 on the side surface of the second nozzle 13, on the one hand, it provides guidance for the dye liquor to reach near the liquid spraying port, and on the other hand, it makes the second nozzle 13 in a hollow structure, saving the input cost.

[0039] In one embodiment, the outlet end of the second nozzle 13 is sealingly connected to the inner wall of the first pipe 14, and the second nozzle 13 is movable along the inner wall of the first pipe 14.

[0040] By sealingly connecting the outlet end of the second nozzle 13 to the inner wall of the first pipe 14, it effectively prevents the dye solution in the liquid supply channel 30 from leaking into the second pipe without passing through the liquid spraying holes, ensuring that the fabric in the fabric dyeing channel 11 is evenly dyed.

[0041] In one embodiment, the outlet end of the second nozzle 13 is inclined inward along the circumference to form a first inclined surface 131, and the outlet end of the first nozzle 12 is inclined inward along the circumference to form a second inclined surface 122. The inclination degrees of the first inclined surface 131 and the second inclined surface 122 are the same.

[0042] Through the cooperation of the first inclined surface 131 and the second inclined surface 122, an annular liquid spraying hole is formed between the first inclined surface 131 and the second inclined surface 122, so as to facilitate the dye solution to be sprayed onto the fabric in the fabric dyeing channel 30; by setting the inclination degrees of the first inclined surface 131 and the second inclined surface 122 to be the same, it avoids damage to each other when the two inclined surfaces come into contact.

[0043] In one embodiment, a flange 123 is provided at the inlet end of the first nozzle 12. The flange 123 is configured to connect the first nozzle 12 and the guiding member 124. The guiding member 124 is in a conical shape with an outer diameter decreasing from outside to inside. The guiding member 124 is configured to increase the inlet area of the first nozzle 12.

[0044] By providing the guiding member 124 at the inlet of the first nozzle 12, the inlet area of the first nozzle 12 is increased, facilitating the fabric to quickly and accurately enter the first channel 120, saving time and improving the fabric dyeing efficiency.

[0045] In one embodiment, the inlet end of the first pipe 14 is in a conical shape with an outer diameter decreasing from outside to inside.

[0046] By setting the inlet end of the first pipe 14 to be in a conical shape with an outer diameter decreasing from outside to inside, it is convenient for the bottoms of the first nozzle 12 and the second nozzle 13 to communicate with the second channel, and at the same time, it is convenient for more dye solution to flow into the liquid spraying port.

[0047] A dyeing machine includes the adjustable nozzle structure according to any one of the above.

[0048] The above embodiments only illustrate the basic principles and characteristics of the present application. The present application is not limited by the above examples.
