Description

Technical Field

[0001] This utility model belongs to the field of dyeing technology, specifically relating to roller dyeing machines, and more particularly to roller structures and fabric dyeing machines. Background Technology

[0002] Dyeing machines are used for dyeing, bleaching, boiling, and washing of garments such as wool sweaters, acrylic sweaters, and cotton sweaters. They can also be used for dyeing finished products such as gloves, socks, and towels. Traditional small dyeing machines can only dye a whole piece of fabric. When dyeing fabric scraps, each scrap needs to be sewn together, and the fabric scraps must be of uniform thickness. Roller-type dyeing machines can put fabric scraps directly into the chamber without sorting or sewing, and can adapt to dyeing fabrics of different sizes and lengths.

[0003] In related technologies, cage dyeing machines rely solely on the rotation of the drum, and the fabric can only be dyed by immersing it in the dye solution inside the chamber. This immersion dyeing process often results in uneven dyeing.

[0004] Therefore, how to solve the problem of uneven dyeing is a technical problem that urgently needs to be solved in this field.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0037] Research has revealed the following drawbacks of existing technologies: In related technologies, cage dyeing machines rely solely on the rotation of the drum, and the fabric can only be dyed by immersing it in the dye solution within the chamber, which often results in uneven dyeing.

[0038] Therefore, how to solve the problem of uneven dyeing is a technical problem that urgently needs to be solved in this field.

[0039] The shortcomings of the above solutions are the result of the utility model inventor's practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as contributions made by the utility model inventor to this disclosure.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] like Figures 1 to 6 As shown, some embodiments provide a roller structure for a dyeing machine, including: an outer cylinder 21 and an inner cylinder 22. The outer cylinder 21 is configured to hold dye liquor; the inner cylinder 22 is configured to hold fabric. A dye liquor holding cavity 23 is formed between the outer cylinder 21 and the inner cylinder 22, and a fabric holding cavity 24 is formed on the inner wall of the inner cylinder 22. The dye liquor holding cavity 23 and the fabric holding cavity 24 are connected through a through hole 27 on the inner cylinder 22. When the roller structure 2 rotates as a whole, the dye liquor will continuously shuttle between the dye liquor holding cavity 23 and the fabric holding cavity 24.

[0043] Please see Figure 3 and combined Figure 4 The dye liquor holding cavity 23 is provided with at least one set of spraying components 4, and part of the spraying components 4 extends into the fabric holding cavity 24; wherein the spraying components 4 are configured to draw liquid from the dye liquor holding cavity 23 and spray it onto the fabric in the fabric holding cavity 24.

[0044] Please see Figure 3 and combined Figure 4 The following describes the composition and structure of the spray assembly 4. The spray assembly 4 includes a pipe 41, on which at least one nozzle 42 is provided. The pipe 41 is located inside the dye liquor holding chamber 23. The nozzle 42 extends into the fabric holding chamber 24. The nozzle 42 is configured to spray liquid into the fabric holding chamber 24. The pipe 41 is connected to the dye liquor holding chamber 23. By spraying dye liquor onto the fabric through the nozzle 42, the circulation effect of the dye liquor is improved, and the penetration effect of the dye liquor is enhanced.

[0045] Please see Figure 4 and combined Figure 5To prevent the nozzle 42 from becoming clogged and difficult to repair after prolonged use, a buffer tube 43 is installed at the connection between the pipe 41 and the nozzle 42. It should be noted that the buffer tube 43 is detachably connected to both the pipe 41 and the nozzle 42, and its inner wall has a tapered design at both ends. A ring spring 44 is located at the center of the buffer tube 43. After the dye liquor passes through the buffer tube 43, the fabric fibers within the dye liquor are suitable for winding around the ring spring 44. The tapered design of the buffer tube 43 allows the dye liquor to fall along the inclined surface onto the ring spring 44, thus achieving a filtering effect without reducing the hydraulic pressure. When cleaning is required, the buffer tube 43 can be removed for cleaning, making the operation simple.

[0046] Please see Figure 3 To further improve the dyeing effect, protrusions 25 are provided on the inner wall of the inner cylinder 22. These protrusions 25 surround the nozzles 42, not only protecting them but also creating a textured contact surface with the fabric as the roller structure 2 rotates, causing the fabric to be irregularly turned and compressed. The protrusions 25 are arranged along the direction of the nozzles 42. A recess 26 is located at the center of each protrusion 25; the nozzles 42 are positioned at the center of the recess 26.

[0047] Please see Figure 1 and combined Figure 2 Some embodiments also provide a fabric dyeing machine, including: a housing 1 and a roller structure 2 as described above; wherein the roller structure 2 is rotatably connected inside the housing 1. Specifically, similar to related technologies, a drive structure is also provided inside the housing 1 to drive the roller structure 2 to rotate, which will not be described in detail here.

[0048] Please see Figure 1 An operating box 11 is provided on the top of the housing 1. A cover 3 is provided on one side of the housing 1; the cover 3 is adapted to seal the opening of the roller structure 2. A viewing glass 31 is provided at the center of the cover 3. It should be further noted that the opening of the roller structure 2 is located on the side of the housing 1, which is different from the opening on the top in related technologies. This is more conducive to sealing under high pressure and high temperature, and is beneficial to improving the dyeing effect.

[0049] In summary, by setting up the spray component 4, the fabric can be sprayed with dye while being soaked and dyed, which not only improves the dyeing efficiency and makes the dye circulation effect better and the penetration effect better, but also improves the uniformity of dyeing of the fabric. By setting up the protrusion 25, the fabric is continuously turned and squeezed during the rolling process, which further improves the dyeing uniformity. By setting up the buffer tube 43 with the ring spring 44, the fabric fibers in the dye liquor are filtered during the circulation of dye liquor, thereby effectively avoiding the clogging of the nozzle.
