[0002] With the vigorous development of the economy and the continuous improvement of science and technology, dyeing and printing equipment is also developing rapidly, placing higher demands on the dyeing quality and efficiency of fabrics. A common and important step in the dyeing process of a dyeing machine is to spray dye onto the fabric surface using a spraying assembly, allowing the fabric to undergo initial dyeing as it passes through the dyeing channel.

[0003] However, current liquid spraying components typically use a fixed flow nozzle structure, and the flow rate of the sprayed liquid cannot be flexibly adjusted according to the type, thickness, or dyeing requirements of the fabric. This often results in insufficient or excessive liquid spraying when dyeing fabrics of different weights or fabric structures, leading to poor compatibility and difficulty in adapting to the dyeing needs of multiple types of fabrics, thus limiting the applicability and flexibility of the equipment.

[0032] Please see Figures 1 to 4 As shown in the embodiment of this application, an adjustable nozzle structure includes at least one set of support components 50 and a coaxially arranged outer cylinder 10, bracket 20, first spray ring 30, and a plurality of second spray rings 40, wherein:

[0033] The bracket 20 is set inside the outer cylinder 10 and has an installation channel along its own axial direction. The first spray ring 30 and several second spray rings 40 are coaxially set in the installation channel. The first spray ring 30 is connected to the top of the bracket 20. Both the first spray ring 30 and the second spray ring 40 are set as a conical structure with a larger top and a smaller bottom.

[0034] A plurality of second spray rings 40 are sequentially sleeved in a vertical direction. The diameter of the top end of the second spray ring 40 is larger than the diameter of the bottom end of the first spray ring 30. The uppermost second spray ring 40 is sleeved on the first spray ring 30. The first spray ring 30 and the plurality of second spray rings 40 form a dyeing channel extending along its own axis. An annular spray hole 41 is formed between the first spray ring 30 and the second spray ring 40 and / or between at least two adjacent second spray rings 40. A support assembly 50 is provided at the spray hole 41. The support assembly 50 is configured to support the first spray ring 30 or the second spray ring 40 above the spray hole 41 so as to adjust the size of the spray hole by changing the support height.

[0035] The outer cylinder 10 is provided with a liquid supply port 11. After the dyeing liquid enters the outer cylinder 10 through the liquid supply port 11, it is sprayed onto the fabric in the dyeing channel through the spray hole 41.

[0036] By coaxially arranging a first spray ring 30 and several second spray rings 40 inside the outer cylinder 10, and adjusting the corresponding spray holes 41 through the support assembly 50, an adjustable multi-nozzle structure is provided to ensure that the spray volume of the spray holes 41 is uniform and adjustable, thereby further improving the flexibility of spray volume adjustment.

[0037] In one embodiment, the second spray ring 40 can be fitted onto the first spray ring 30 in a close fit, and the diameter of the bottom of the first spray ring 30 is the same as the diameter of the bottom of the second spray ring 40.

[0038] By setting a first spray ring 30 and a second spray ring 40 that can fit together, it is easy to ensure that the flow rate of the spray holes 41 between the first spray ring 30 and the second spray ring 40 is balanced. By setting the bottom diameter of the first spray ring 30 and the second spray ring 40 to be the same, the smooth movement of the fabric in the dyeing channel is ensured, and the fabric blockage is avoided.

[0039] In one embodiment, the support assembly 50 includes a plurality of support members 51, which are detachably disposed at intervals along the circumferential direction on the first spray ring 30 and / or the second spray ring 40 at the spray hole 41. The support members 51 are provided with inclined support surfaces that abut against adjacent first spray ring 30 and / or second spray ring 40.

[0040] By using spaced support members 51, stable support is provided for the empty space of the spray hole 41 on the one hand, and the flow of dye liquor is facilitated on the other hand, ensuring the stability of the spraying process.

[0041] In one embodiment, the tilt angle of the support surface is the same as the side tilt angle of the first spray ring 30.

[0042] By setting the tilt angle of the support surface to be the same as the tilt angle of the side of the spray ring, it is ensured that the support 51 fits against the outer side of the corresponding support ring, thereby ensuring the stability of the overall structure.

[0043] In one embodiment, the support member 51 is uniformly disposed along the circumferential direction on the second spray ring 40 located below the spray hole 41.

[0044] By uniformly arranging the support members 51 along the axis of rotation and placing them on the lower second spray ring 40, it is possible to ensure that the dye liquor passes evenly through the spray holes 41 in the circumferential direction, while also facilitating the standardized processing of the second spray ring 40, which is beneficial for installation and cost savings.

[0045] In one embodiment, the support member 51 is configured with a "U"-shaped structure, and the support member 51 includes a first support rod 510, a second support rod 511, and a connecting rod 512, wherein:

[0046] The connecting rod 512 is connected to the first support rod 510 and the second support rod 511 at its two ends along its length. The connecting rod 512 is provided with a support surface along its length. The second spray ring 40 is provided with a number of mounting holes 42. The first support rod 510 and the second support rod 511 are respectively detachably installed in the corresponding mounting holes 42.

[0047] Specifically, the first support rod 510 and the second support rod 511 are of the same length.

[0048] Specifically, the connecting rod 512 is set along the direction of the length of the second spray ring 40 itself.

[0049] By setting up a U-shaped support 51 and mounting hole 42, the structure is not only simple and easy to install, but also the interference with the flow of dye liquid at the spray hole 41 is small, which facilitates the rapid passage of dye liquid.

[0050] In one embodiment, the installation depth of the first support rod 510 and the second support rod 511 in the mounting hole 42 can be adjusted or the support member 51 of different specifications can be replaced to adjust the distance between the support surface and the inner wall of the corresponding second spray ring 40.

[0051] Specifically, the lengths of the first support rod 510 and the second support rod 511 of the support members 51 of different specifications are different.

[0052] By adjusting the installation depth or replacing the support component 51 with one of different specifications, it is easy to adjust the distance between the support surface and the inner wall of the corresponding second spray ring 40, thereby adjusting the size of the spray hole 41 and improving the applicability of the overall structure.

[0053] In one embodiment, the bracket 20 includes a first mounting ring 21, a second mounting ring 22, a third mounting ring 23, a fourth mounting ring 24, and a plurality of connectors 25, wherein:

[0054] The first mounting ring 21 and the second mounting ring 22 are coaxially arranged, and a plurality of connectors 25 are evenly arranged around the axis of the first mounting ring 21 in the circumferential direction. Each connector 25 is connected to the first mounting ring 21 and the second mounting ring 22 at both ends along its own length direction.

[0055] A third mounting ring 23 is fixedly installed at the top of the first spray ring 30. The third mounting ring 23 is screwed to the first mounting ring 21. A fourth mounting ring 24 is sleeved on the outer wall of the bottommost second spray ring 40. The fourth mounting ring 24 is screwed to the second mounting ring 22.

[0056] The combination of various mounting rings and several connectors 25 provides a simple and stable support structure.

[0057] In one embodiment, the adjustable nozzle structure further includes a straight cylinder 60, which is fitted onto the lowermost second spray ring 40, and the liquid supply port 11 is located on one side of the straight cylinder 60 in the horizontal direction; the connecting member 25 is configured as a flow divider, which is configured to divert the dye liquid that is about to enter the spray hole 41 in the outer cylinder 10 to avoid swirling.

[0058] By setting a straight cylinder, it is easy to guide the dyed fabric, and by setting the connector 25 as a diverter, it is easy to divert the dye liquor entering the outer cylinder 10, further ensuring that the spray hole 41 sprays out the dye liquor evenly.
