[0017] A dyeing method of a cloth dyeing device for textile processing comprises the following steps:

[0018] S1: When dyeing cloth, firstly, the first motor is controlled to start, the start of the first motor drives the rotation of the first threaded rod, the rotation of the first threaded rod drives the first slider to slide inside the side plate, the movement of the first slider drives the movement of the connecting plate, the movement of the connecting plate drives the movement of the first mounting plate, the movement of the first mounting plate drives the pressure roller to move up, so that the pressure roller and the guide roller are at the same level, then the cloth passes through the guide roller and the pressure roller and is installed, the first motor is controlled to start again, the first threaded rod is rotated in the opposite direction, and similarly the two pressure rollers are moved down into the dye box, so that the cloth is immersed in the dye for dyeing;

[0019] S2: During dyeing, the second motor is controlled to start and drive the second threaded rod to rotate, the rotation of the second threaded rod drives the second slider to move back and forth, the movement of the second slider drives the movement of the second mounting plate through the second connecting block, the movement of the second mounting plate drives the movement of the mixing roller, so that the first mounting plate moves back and forth in the dye box to stir the dye in the dye box;

[0022] S5: After dyeing is completed, the first motor is controlled to start in the same way, so that the connecting plate and the pressure roller move up. The connecting plate moves up to drive the pressure roller to move up to remove the cloth. At the same time, the movement of the connecting plate drives the second mounting plate to move up through the first connecting block.

[0024] 1. The present invention is arranged by cooperating with each other through the pressing component and the moving component. When the cloth is dyed, the first motor is first controlled to start, and the start of the first motor drives the rotation of the first threaded rod. The rotation of the first threaded rod drives the first slider to slide inside the side plate. The movement of the first slider drives the movement of the connecting plate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] The pressing assembly includes a pressing roller 4 arranged inside the dye box 1. Two pressing rollers 4 are provided. One end of each of the two pressing rollers 4 is installed with a first mounting plate 5. The two first mounting plates 5 are fixedly connected by a connecting plate 6. The connecting plate 6 is installed on the side wall of the side plate 2 through a moving assembly.

[0039] The moving assembly includes a first slider 7 fixedly mounted on the top of the connecting plate 6, the first slider 7 is slidably mounted inside the side plate 2, the inner wall of the first slider 7 is threadedly connected with a first threaded rod 8, the bottom end of the first threaded rod 8 is mounted with a first motor 9, and the first motor 9 is arranged inside the side plate 2.

[0040] When dyeing cloth, first control the first motor 9 to start, the start of the first motor 9 drives the rotation of the first threaded rod 8, the rotation of the first threaded rod 8 drives the first slider 7 to slide inside the side plate 2, the movement of the first slider 7 drives the movement of the connecting plate 6, the movement of the connecting plate 6 drives the movement of the first mounting plate 5, the movement of the first mounting plate 5 drives the pressure roller 4 to move up, so that the pressure roller 4 and the guide roller 3 are at the same level, then the cloth passes through the guide roller 3 and the pressure roller 4, and the first motor 9 is controlled to start again to make the first threaded rod 8 rotate in the opposite direction. Similarly, the two pressure rollers 4 are moved down into the dye box 1, so that the cloth is immersed in the dye for dyeing, and the two pressure rollers 4 can move up and down, which is convenient for the placement of the cloth before dyeing, thereby improving the convenience and safety of cloth dyeing.

[0041] When the cloth is dyed, one end of the cloth can be continuously rolled up to facilitate continuous dyeing.

[0042] like Figures 1 to 8 As shown, the mixing assembly includes a mixing roller 10 arranged inside the dye box 1, and the mixing roller 10 is arranged below the pressure roller 4. Both ends of the mixing roller 10 are fixedly connected with a first rotating shaft 12, and the outer wall of one of the first rotating shafts 12 is installed with a second mounting plate 13 through a rotating assembly, and a second connecting block 14 is fixedly connected to one side of the top of the second mounting plate 13, and a second slider 15 is arranged on the outer wall of the second connecting block 14. The second slider 15 is slidably installed inside the side plate 2, and the inner wall of the second slider 15 is threadedly connected with a second threaded rod 16, and a second motor 17 is installed at one end of the second threaded rod 16.

[0043] When the cloth is dyed, the second motor 17 is controlled to start and drive the second threaded rod 16 to rotate. The rotation of the second threaded rod 16 drives the second slider 15 to move back and forth. The movement of the second slider 15 drives the movement of the second mounting plate 13 through the second connecting block 14. The movement of the second mounting plate 13 drives the movement of the mixing roller 10, so that the first mounting plate 5 moves back and forth in the dye box 1, and the dye in the dye box 1 is stirred to prevent precipitation or impurities from appearing in the dye liquid, resulting in uneven dye concentration in the dye liquid, which ultimately affects the dyeing effect. The reciprocating movement of the mixing roller 10 in the dye liquid helps to stir the dye liquid and ensure the uniformity of dyeing.

[0044] like Figure 6 As shown, the top end of the second mounting plate 13 is fixedly connected with the first connecting block 11 , and the first connecting block 11 is slidably mounted inside the connecting plate 6 .

[0045] When the second mounting plate 13 moves, the movement of the second mounting plate 13 drives the movement of the first connecting block 11, and the first connecting block 11 slides inside the bottom end of the connecting plate 6. When the connecting plate 6 moves upward, the movement of the connecting plate 6 drives the second mounting plate 13 upward through the first connecting block 11, and the movement of the second mounting plate 13 drives the movement of the mixing roller 10, so that the mixing roller 10 is separated from the dye liquid in the dye box 1, which is convenient for maintenance of the mixing roller 10.

[0046] like Figure 6 As shown, the second connecting block 14 is slidably connected to the second sliding block 15 .

[0047] When the connecting plate 6 drives the second mounting plate 13 to move upward, the movement of the second mounting plate 13 drives the second connecting block 14 to slide out from the interior of the second sliding block 15. Similarly, during installation, the second mounting plate 13 is installed inside by embedding the second connecting block 14 into the interior of the second sliding block 15.

[0048] like Figures 1 to 8 As shown, the rotating assembly includes a pulley group 18 installed on the outer wall of the first rotating shaft 12, the pulley group 18 is installed inside the second mounting plate 13, the top of the pulley group 18 is installed on the outer wall of the second rotating shaft 19, the outer wall of the second rotating shaft 19 is fixedly connected with a gear 20, the bottom end of the gear 20 is meshedly connected with a rack plate 21, and the rack plate 21 is fixedly installed on the top of the dye box 1.

[0049] The rack plate 21 is slidably connected to the second mounting plate 13;

[0050] When the mixing roller 10 moves in the dye box 1, the second mounting plate 13 slides on one side of the side plate 2, and the movement of the second mounting plate 13 drives the movement of the gear 20, and the gear 20 moves and engages with the rack plate 21 to rotate, and the rotation of the gear 20 drives the rotation of the second rotating shaft 19, and the rotation of the second rotating shaft 19 drives the first rotating shaft 12 to rotate through the pulley group 18, and the rotation of the first rotating shaft 12 drives the mixing roller 10 to rotate, so that the mixing roller 10 rotates when it reciprocates in the dye box 1, further improving the mixing effect of the dye solution, accelerating the movement of dye molecules in the dye solution, and making the dye diffuse into the fibers of the cloth more quickly, which helps to shorten the dyeing time and improve production efficiency.

[0051] like Figure 4 and Figure 8 As shown, a liquid inlet 22 is provided on the inner wall of the mixing roller 10 , and a filter screen 23 is installed inside the mixing roller 10 .

[0052] When the mixing roller 10 moves in the dye box 1, the dye liquid in the dye box 1 enters the mixing roller 10 through the liquid inlet 22, the dye liquid contacts the filter screen 23, and the precipitate or impurities in the dye liquid are filtered through the filter screen 23 to prevent the precipitate and impurities from adhering to the surface of the cloth to form defects or spots, which affect the dyeing quality and appearance of the cloth. Filtering the precipitate or impurities in the dye liquid through the filter screen 23 helps to improve the quality of the dyed cloth.

[0053] like Figure 8 As shown, a guide plate 27 is fixedly installed inside the mixing roller 10 , and the guide plate 27 is arranged on one side of the liquid inlet 22 .

[0054] The possibility of the sediment or impurities retained by the filter screen 23 being discharged from the liquid inlet 22 is reduced as much as possible, so that the sediment or impurities remain inside the mixing roller 10, which is convenient for unified treatment later.

[0055] like Figure 4 and Figure 7 As shown, both ends of the filter screen 23 are fixedly connected with a third rotating shaft 24 , and the third rotating shaft 24 is rotatably installed inside the mixing roller 10 .

[0056] When the mixing roller 10 rotates, the filter screen 23 rotates inside the mixing roller 10 due to the gravity of the filter screen 23 itself, thereby improving the effect of the filter screen 23 in filtering the sediment or impurities in the dye solution.

[0057] like Figure 7 As shown, the outer wall of the third rotating shaft 24 is fixedly connected to a limiting block 25 , and the limiting block 25 is slidably installed inside a slide groove 26 , and the slide groove 26 is opened inside the mixing roller 10 .

[0058] When the filter screen 23 rotates inside the mixing roller 10, the rotation of the third rotating shaft 24 drives the rotation of the limit block 25, and the limit block 25 is limited by the slide groove 26, so that the filter screen 23 can only swing at a certain angle inside the mixing roller 10, preventing the filter screen 23 from contacting the guide plate 27 during the swinging process, thereby improving the stability and reliability of the filter screen 23 during rotation.

[0059] A dyeing method of a cloth dyeing device for textile processing comprises the following steps:

[0060] S1: When dyeing cloth, firstly, the first motor 9 is controlled to start, and the start of the first motor 9 drives the rotation of the first threaded rod 8, and the rotation of the first threaded rod 8 drives the first slider 7 to slide inside the side plate 2, and the movement of the first slider 7 drives the movement of the connecting plate 6, and the movement of the connecting plate 6 drives the movement of the first mounting plate 5, and the movement of the first mounting plate 5 drives the pressure roller 4 to move up, so that the pressure roller 4 and the guide roller 3 are at the same level, and then the cloth passes through the guide roller 3 and the pressure roller 4 and is installed, and the first motor 9 is controlled to start again, so that the first threaded rod 8 rotates in the opposite direction, and similarly, the two pressure rollers 4 are moved down into the dye box 1, so that the cloth is immersed in the dye for dyeing;

[0061] S2: During dyeing, the second motor 17 is controlled to start and drive the second threaded rod 16 to rotate. The rotation of the second threaded rod 16 drives the second slider 15 to move back and forth. The movement of the second slider 15 drives the movement of the second mounting plate 13 through the second connecting block 14. The movement of the second mounting plate 13 drives the movement of the mixing roller 10, so that the first mounting plate 5 moves back and forth in the dye box 1 to stir the dye in the dye box 1.

[0062] S3: At the same time, the movement of the second mounting plate 13 drives the movement of the gear 20, and the gear 20 moves and meshes with the rack plate 21 to rotate, and the rotation of the gear 20 drives the rotation of the second rotating shaft 19, and the rotation of the second rotating shaft 19 drives the first rotating shaft 12 to rotate through the pulley group 18, and the rotation of the first rotating shaft 12 drives the mixing roller 10 to rotate, so that the mixing roller 10 rotates when reciprocating in the dye box 1 to fully stir the dye in the dye box 1;

[0063] S4: When the mixing roller 10 rotates, the filter screen 23 rotates inside the mixing roller 10, and the rotation of the filter screen 23 drives the rotation of the third rotating shaft 24, and the rotation of the third rotating shaft 24 drives the rotation of the limit block 25. The limit block 25 is limited by the slide groove 26, so that the filter screen 23 swings inside the mixing roller 10 to filter impurities in the dye solution;

[0064] S5: After dyeing is completed, the first motor 9 is controlled to start in the same way, so that the connecting plate 6 and the pressing roller 4 move upward. The upward movement of the connecting plate 6 drives the pressing roller 4 to move upward to remove the cloth. At the same time, the movement of the connecting plate 6 drives the second mounting plate 13 to move upward through the first connecting block 11. The movement of the second mounting plate 13 drives the movement of the mixing roller 10, so that the mixing roller 10 is separated from the dye liquid in the dye box 1, and the mixing roller 10 is maintained.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
