Description

Technical Field

[0001] This utility model relates to the field of dyeing equipment technology, and in particular to an adjustable nozzle and a dyeing machine. Background Technology

[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. Utility Model Content

[0004] The purpose of this application is to provide an adjustable nozzle to solve the problem that the flow rate of the nozzle in the prior art cannot be flexibly adjusted; in addition, the purpose of this application is to provide a dyeing machine including the adjustable nozzle.

[0005] To achieve this objective, the following technical solution is adopted in this application:

[0006] This application provides an adjustable nozzle, which includes at least one set of support components and a first nozzle, a second nozzle, and a mounting ring coaxially arranged in a vertical direction, wherein:

[0007] The second nozzle is fitted at the lower end of the first nozzle and the first nozzle can be adjusted in the vertical direction. An annular spray hole is formed between the first nozzle and the second nozzle. The first nozzle and the second nozzle form a dyeing channel for the fabric to pass through in the vertical direction. The dye liquid is sprayed out through the spray hole onto the fabric in the dyeing channel.

[0008] The mounting ring is height-adjustably positioned above the second nozzle, and the first nozzle passes through the mounting ring. A support assembly is positioned between the mounting ring and the second nozzle. The support assembly is configured to adjust the distance between the mounting ring and the top surface of the second nozzle to change the size of the spray hole.

[0009] Optionally, the adjustment assembly includes a mounting ring and at least one set of support components, wherein the mounting ring is rotatably disposed above the second nozzle along the axis of the two nozzles and interferes with the first nozzle in the vertical direction;

[0012] Each support rod corresponds to a set of mounting slots. Each set of mounting slots includes several mounting slots of different depths. The support rod is set vertically on the bottom surface of the mounting ring. Several mounting slots are spaced apart on the top surface of the second nozzle in a circumferential direction. The support rod and the mounting slot are located in the same circumferential direction, and the support rod can abut against the bottom surface of the mounting slot.

[0013] Optionally, the depth of several mounting slots within each mounting slot group can decrease or increase sequentially along the circumferential direction.

[0014] Optionally, the support rod is adapted to a single mounting slot, and when the support rod is set in the mounting slot, the side wall of the support rod abuts against the inner wall of the corresponding mounting slot.

[0015] Optionally, the support assembly includes four support rods and four sets of mounting slots.

[0017] Optionally, the outer wall of the first nozzle is provided with a first threaded section along the circumferential direction, and the inner wall of the second nozzle is provided with a corresponding second threaded section, the first threaded section and the second threaded section being compatible.

[0018] Optionally, an annular limiting platform is provided below the second threaded segment, and the annular limiting platform is configured to limit the first threaded segment in the vertical direction.

[0019] A dyeing machine comprising any of the aforementioned adjustable nozzles.

[0020] Compared with the prior art, the adjustable nozzle proposed in this application has the following advantages:

[0021] 1) The combination structure of mounting ring, support rod, mounting groove with inconsistent depth and threaded section is simple in structure and easy to operate.

[0030] Please see Figures 1 to 4 As shown in the embodiment of this application, an adjustable nozzle includes at least one set of support components 40 and a first nozzle 10, a second nozzle 20, and a mounting ring 30 arranged coaxially in the vertical direction, wherein:

[0031] The second nozzle 20 is fitted at the lower end of the first nozzle 10 and the first nozzle 10 can be adjusted in the vertical direction. An annular spray hole 50 is formed between the first nozzle 10 and the second nozzle 20. The first nozzle 10 and the second nozzle 20 form a dyeing channel 11 for the fabric to pass through in the vertical direction. The dyeing liquid is sprayed out through the spray hole 50 onto the fabric in the dyeing channel.

[0032] The mounting ring 30 is height-adjustably positioned above the second nozzle 20, and the first nozzle 10 passes through the mounting ring 30. The support assembly 40 is positioned between the mounting ring 30 and the second nozzle 20. The support assembly 40 is configured to adjust the distance between the mounting ring 30 and the top surface of the second nozzle 20 to change the size of the spray hole 50.

[0033] Specifically, an annular pressure-bearing surface 12 is provided on the outer wall of the first nozzle 10, and the annular pressure-bearing surface 12 abuts against the upper surface of the mounting ring 30.

[0034] By coaxially sleeved first nozzle 10 and second nozzle 20 to form an annular spray hole 50 therebetween, and mounting first nozzle 10 on mounting ring 30, the relative height of first nozzle 10 and second nozzle can be adjusted by cooperating with support component 40 to adjust the height of mounting ring 30, thereby realizing the adjustment of the size of spray hole 50. This provides a nozzle structure that can flexibly adjust the spray flow rate, thereby improving the adaptability to different types of fabrics and the uniformity of dyeing.

[0035] In one embodiment, the support assembly 40 includes at least one support rod 41 and at least one set of mounting slots 42, wherein:

[0036] Each support rod 41 corresponds to a set of mounting grooves 42. Each set of mounting grooves 42 includes several mounting grooves of different depths. The support rod 41 is set vertically on the bottom surface of the mounting ring 30. Several mounting grooves are spaced apart on the top surface of the second nozzle 20 in the circumferential direction. The support rod 41 and the mounting groove are located in the same circumferential direction and the support rod 41 can abut against the bottom surface of the mounting groove.

[0037] Specifically, the length of the support rod 41 is not less than the depth of the deepest mounting groove.

[0038] Specifically, each set of mounting slots 42 includes a first mounting slot 420, a second mounting slot 421, a third mounting slot 422, and a fourth mounting slot 423. The first mounting slot 420 has a depth of 6mm, the second mounting slot 421 has a depth of 5mm, the third mounting slot 422 has a depth of 4mm, and the fourth mounting slot 423 has a depth of 3mm.

[0039] By combining the support rod 41 with the mounting groove of varying depths, not only is multi-level adjustment of the nozzle height achieved, enhancing the flexibility of liquid volume adjustment, but also ensuring adjustment accuracy.

[0040] In one embodiment, the depth of several mounting slots within each mounting slot group 42 decreases or increases sequentially along the circumferential direction.

[0041] By sequentially decreasing or increasing the depth of several mounting slots within the mounting slot group 42, the nozzle spacing is gradually adjusted, improving the continuity of adjustment and thus avoiding abrupt changes during the adjustment process, thereby improving the uniformity of liquid spraying.

[0042] In one embodiment, the support rod 41 is adapted to a single mounting slot, and when the support rod 41 is disposed in the mounting slot, the side wall of the support rod 41 abuts against the inner wall of the corresponding mounting slot.

[0043] By adapting the support rod 41 to a single mounting slot and having its side wall abut against the inner wall of the mounting slot, a stable locking of the nozzle position is achieved, thereby ensuring that the nozzle is not easily loosened or shifted after adjustment.

[0044] In one embodiment, the support assembly 40 includes four support rods 41 and four sets of mounting grooves 42. The four support rods 41 are evenly spaced and fixedly disposed on the mounting ring 30 along the circumferential direction. The four sets of mounting grooves 42 are evenly spaced and disposed on the top surface of the second nozzle 20 along the circumferential direction. Each set of mounting grooves 42 includes four mounting grooves evenly spaced along the circumferential direction.

[0045] By setting the support assembly 40 as four support rods 41 and four sets of mounting grooves 42, and distributing them evenly along the circumference, symmetrical support of the nozzle is achieved, ensuring that the corresponding nozzle and mounting ring 30 are subjected to balanced forces, thereby improving the stability and durability of the nozzle.

[0046] In one embodiment, the support rod 41 is provided with a guide surface 410 that is inclined away from the mounting groove, and the guide surface 410 is provided at the bottom end of the support rod 41 in a circumferential direction.

[0047] By setting a guide surface 410 at the bottom of the support rod 41, the support rod 41 can quickly and accurately enter the corresponding mounting groove, thereby improving the adjustment efficiency and accuracy of the spray hole 50.

[0048] In one embodiment, the outer wall of the first nozzle 10 is provided with a first threaded section 13 along the circumferential direction, and the inner wall of the second nozzle 20 is provided with a corresponding second threaded section 21, wherein the first threaded section 13 and the second threaded section 21 are adapted to each other.

[0049] By setting a matching threaded section between the first nozzle 10 and the second nozzle 20, not only is precise thread adjustment of the nozzle spacing achieved, but the stability of the connection between the first nozzle 10 and the second nozzle 20 is further ensured.

[0050] In one embodiment, an annular limiting platform 210 is provided below the second threaded segment 21, and the annular limiting platform 210 is configured to limit the first threaded segment 13 in the vertical direction.

[0051] By setting an annular limiting platform 210 below the second threaded section 21, the vertical direction of the first threaded section 13 is limited, thereby preventing the first nozzle 10 from being over-screwed in or falling off, thus further improving the reliability of nozzle adjustment.

[0052] A dyeing machine comprising any of the aforementioned adjustable nozzles.

[0053] The above embodiments merely illustrate the basic principles and characteristics of this application. This application is not limited to the above examples.
