[0055] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] Existing textile printing and dyeing post-processing equipment suffers from a relatively complex and labor-intensive fabric threading process during the washing process. Specifically, with the existing setup, the fabric needs to be threaded through the washing tank during washing. The washing tank is equipped with many guide rollers, so the fabric needs to be threaded in from one side of the washing tank, then passed through each guide roller in sequence before exiting the washing tank. Moreover, since the washing tank contains washing liquid, workers need to wear waterproof gloves during the fabric threading process to avoid getting their hands wet. Overall, the existing equipment suffers from a complex and labor-intensive fabric threading process.

[0057] Therefore, please refer to Figure 1 - Figure 4 This application provides a 700 post-processing device for textile printing and dyeing fabrics, wherein... Figure 1 This is a schematic diagram of the overall structure in the first state; Figure 2 This is a schematic diagram of the overall structure in the second state; Figure 3 This is a schematic cross-sectional view of the overall structure in the second state; Figure 4 This is a structural schematic diagram of the adjustment component 400.

[0058] Please refer to Figure 1 - Figure 3 In this application, the first direction X is the front-to-back direction of the washing tank 100, the second direction Y is the up-down direction of the washing tank 100, and the third direction Z is the left-to-right direction of the washing tank 100.

[0059] The post-processing device for placing the dyed fabric 700 of this application includes a washing tank 100; multiple first guide rollers 200 are rotatably connected within the washing tank 100 along a first direction X, and some of the first guide rollers 200 are located below the surface of the washing liquid. Furthermore, this application also includes multiple second guide rollers 300, each second guide roller 300 corresponding to one first guide roller 200 in a second direction Y, i.e., the second guide rollers 300 and first guide rollers 200 are arranged vertically. This application also includes an adjustment component 400 for adjusting the state of the second guide rollers 300. The adjustment component 400 can switch the state of the second guide rollers 300 between a first state and a second state. Specifically, in the first state, the second guide rollers 300 are higher than the washing tank 100, and multiple second guide rollers 300 are in the same plane; in this state, the fabric 700 can be threaded through. In the second state, the second guide rollers 300 and the first guide rollers 200 respectively abut against both sides of the fabric 700.

[0060] The following is a further explanation based on a specific application scenario. When the printed fabric 700 needs to be washed, in order to facilitate the threading of the fabric 700 and prevent the operator's hands from entering the washing tank 100, the second guide rollers 300 can be raised by adjusting the component 400 until all the second guide rollers 300 are a certain distance above the surface of the washing liquid. Then, the operator threads the fabric 700 from one side of the washing tank 100, passing it under the second guide rollers 300 one by one. Next, the second guide rollers 300 are lowered by adjusting the component 400. The second guide roller 300 is brought into contact with the top surface of the fabric 700. As the second guide roller 300 descends, it pulls the fabric 700 downwards, allowing it to enter the washing solution. The fabric 700 continues until its bottom surface contacts the first guide roller 200. Through the pressure of the first and second guide rollers 200 and the presence of the washing solution, residual dye on the fabric 700 is squeezed out and carried away by the washing solution. This process, involving multiple pressures from the first and second guide rollers 200 and the washing solution, completes the washing of the fabric 700. Throughout this process, workers do not need to put their hands into the washing solution to thread the fabric, making it convenient and labor-saving.

[0061] It should be noted that the traction of the fabric 700 is carried out by an external traction device. For example, a traction motor and a drive roller are set at the end of the device. After the first end of the fabric 700 passes through the washing tank 100, it is fixed on the drive roller. The traction motor drives the drive roller to rotate, thereby tractioning the fabric 700 to wind it up.

[0062] This application uses a drive assembly to raise all the second guide rollers 300 to a certain distance above the washing liquid. The fabric 700 can then be inserted into the washing tank 100 from one end, passing sequentially under all the second guide rollers 300 until it passes through the washing tank 100. The drive assembly then controls the second guide rollers 300 to descend until the first guide roller 200 and the second guide roller 300 respectively abut against the bottom and top surfaces of the fabric 700, causing the fabric 700 to penetrate below the washing liquid surface. Through soaking in the washing liquid and the squeezing action of the first and second guide rollers 200 and 300, excess dye on the fabric 700 is removed. Overall, this application improves the convenience and labor-saving aspect of threading the fabric 700.

[0063] Example 1:

[0064] Please refer to Figure 1 , Figure 2 and Figure 4The adjustment assembly 400 of this application includes multiple pairs of first connecting plates 410. The two first connecting plates 410 of each pair are spaced apart in the first direction X, and the two first connecting plates 410 of each pair are slidably connected to the two inner sidewalls of the washing tank 100 along the first direction X. Each second guide roller 300 is rotatably connected to a pair of first connecting plates 410. The adjustment assembly 400 also includes multiple driving members 420, each driving member 420 being used to control the movement of a pair of first connecting plates 410 in the second direction Y.

[0065] For details, please refer to Figure 4 The driving component 420 of this application includes two second connecting plates 421, and two first connecting plates 410 are slidably connected to the two inner sidewalls of the washing tank 100 along the first direction X. Each second connecting plate 421 has a first connecting plate 410 fixedly connected to its side. A first rack 422 is fixedly connected to the side of the second connecting plate 421 away from the first connecting plate 410. The first rack 422 is arranged along the second direction Y, i.e., vertically. A rotating shaft 423 is rotatably connected to the sidewall of the washing tank 100. An adjusting gear 424 is fixedly connected to the shaft end of the rotating shaft 423, and the adjusting gear 424 meshes with the first rack 422. The adjusting assembly 400 also includes a locking structure 425, which can lock the rotation of the rotating shaft 423, ensuring that the rotating shaft 423 cannot rotate.

[0066] For further details, please refer to Figure 4 The locking structure 425 of this application includes an adjusting plate 4251 coaxially fixed to a rotating shaft 423, and a plurality of locking grooves 42511 are provided on the adjusting plate 4251. A locking pin 4252 is slidably disposed on the outer wall of the washing tank 100 along the second direction Y. Here, the locking pin 4252 is located above the adjusting plate 4251. When the locking pin 4252 is inserted into the locking groove 42511, the rotating shaft 423 cannot rotate. When the locking pin 4252 is pulled out from the locking groove 42511, the rotating shaft 423 can rotate.

[0067] The use of the adjustment component 400 will be further described in conjunction with a specific application scenario. When it is necessary to switch the second guide roller 300 from the first state to the second state, that is, when it is necessary to control the second guide roller 300 to rise, first pull out the locking pin 4252 to release the rotation lock of the rotating shaft 423. Then, the rotating shaft 423 can be controlled to rotate, and the second guide roller 300 is driven to rise through the cooperation of the adjusting gear 424 and the first rack 422 until the second guide roller 300 is a certain distance above the washing liquid surface. Then, the locking pin 4252 is inserted into the locking groove 42511, so that the rotating shaft 423 cannot rotate, thereby ensuring that the height of the second guide roller 300 remains unchanged to facilitate the fabric 700 threading operation. Here, the rotating shaft 423 can be driven by a motor or manually.

[0068] Example 2:

[0069] Please refer to Figure 1 and Figure 3 The first guide roller 200 of this application includes an above-water guide roller 210 and an underwater guide roller 220. The installation position of the above-water guide roller 210 is higher than the liquid surface of the washing liquid, and the installation position of the underwater guide roller 220 is lower than the liquid surface of the washing liquid. The above-water guide roller 210 and the underwater guide roller 220 are spaced apart in the third direction Z (that is, in the left-right direction of the washing tank 100).

[0070] For further details, please refer to Figure 3 The water guide roller 210 of this application includes a left guide roller 211 and a right guide roller 212, which are symmetrically arranged about the second guide roller 300.

[0071] The design intent of the first guide roller 200 structure is explained below in the context of a specific application scenario. The underwater guide roller 220 and its cooperating second guide roller 300 allow the dye solution on the fabric 700 to be squeezed out and carried away by the washing liquid. Since the fabric 700 has limited water absorption, if it remains continuously immersed in the washing liquid, the exchange capacity between the surface water of the fabric 700 and the external washing liquid is limited. The above-water guide roller 210 and its cooperating second guide roller 300 can squeeze the fabric 700, increasing its water absorption capacity. Because the left guide roller 211 and right guide roller 212 are both below the second guide roller 300, the squeezed water and the dye attached to it will drip off under gravity during the squeezing process. The combined use of multiple sets of above-water guide rollers 210, underwater guide rollers 220, and second guide rollers 300 ensures a more thorough removal of dye from the fabric 700.

[0072] Example 3:

[0073] Please refer to Figure 3 The textile printing and dyeing fabric 700 post-processing device of this application also includes a number of partitions 500, and these partitions 500 are spaced apart in the washing tank 100 in the third direction Z; the washing tank 100 is divided into a number of sub-tanks 110 by these partitions 500, and each sub-tank 110 is provided with an above-water guide roller 210 and an underwater guide roller 220.

[0074] For further details, please refer to Figure 3 On the third direction Z, starting from the side where the fabric 700 enters the washing tank 100, the height of the partition 500 increases sequentially, and a water replenishment pump 600 is installed at the sub-tank 110 with the highest tank depth among all the sub-tanks 110.

[0075] The following section provides a further explanation based on specific application scenarios. It's important to note that when fabric 700 first enters the washing liquid and is squeezed, the amount of dye not chemically bonded to the fibers is at its highest, resulting in the most dye being cleaned at this point. However, without the partition 500, the dye diffuses to other parts of the washing tank 100, reducing the washing efficiency of fabric 700. The partition 500 of this application divides the washing tank 100 into multiple sub-tanks 110, each equipped with an above-water guide roller 210 and an underwater guide roller 220. This multi-stage washing of fabric 700 significantly improves its washing efficiency. Furthermore, due to the arrangement of the partition 500, the closer to the water inlet of the fabric 700 in the sub-tank 110, the more dye is removed from the washing liquid. Starting from the side where the fabric 700 enters the washing tank 100, the height of the partition 500 is increased sequentially, and a water replenishment pump 600 is installed in the deepest sub-tank 110. It should be understood that the deepest sub-tank 110 is located on the side of the washing tank 100 away from the water inlet of the fabric 700, and the washing liquid in this sub-tank 110 is the clearest. By replenishing water to the sub-tank 110 with the clearest washing liquid, the washing liquid overflows the partition 500 and enters the adjacent sub-tanks 110, thus effectively replenishing all sub-tanks 110 and making the washing liquid more thoroughly utilized.

[0076] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0077] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0078] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
