Description

Technical Field

[0001] This application relates to the field of pretreatment for fabric dyeing, and in particular to a pretreatment apparatus for dyeing glutinous rice wool. Background Technology

[0002] Fabric production requires many processes to complete. After determining the required dye formula, the dye and auxiliaries are determined by the cutting machine. The fabric first undergoes pretreatment processes such as impurity removal, loosening, and oil removal. Then, the dye, auxiliaries, and water are added to the dyeing machine by the dripping machine for dyeing. After the fabric is dyed, it undergoes posttreatment processes such as acid removal, alkali boiling, and washing.

[0003] During the pretreatment process, impurities need to be removed from the fabric, especially for velvet fabric. Because velvet has many fibers that easily shed, it needs to be washed before dyeing. Current washing processes involve immersing the velvet in water and agitating it to separate the loose fibers. However, since the fibers are lightweight, washing only separates them; the fibers remain near the fabric and don't easily sink to the bottom. This means that after washing, when the fabric is removed from the water, the fibers tend to remain attached, leading to reduced dyeing quality in the subsequent dyeing process. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, reduce the amount of detached fluff adhering to the fabric, improve the quality of subsequent dyeing, and provide a pretreatment device for dyeing glutinous rice velvet.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] A pretreatment device for dyeing glutinous rice velvet includes a washing table, an active roller group and a driven roller group disposed on the washing table, and two downward guide rollers disposed at the bottom of the washing table, one of which is close to the active roller group and the other is close to the driven roller group. A fan blade is disposed below the downward guide roller close to the active roller group.

[0007] Preferably, a filter assembly is provided near the lower part of the driven roller assembly.

[0008] Preferably, the filter assembly includes a filter frame and a filter screen detachably disposed on the filter frame.

[0009] Preferably, rotating columns are provided on both sides of the filter frame, and the rotating columns are rotatably connected to the side wall of the washing table; the rotating columns are located in the upper middle part of the filter frame.

[0010] Preferably, a partition is horizontally arranged inside the cleaning table, which divides the interior of the cleaning table into two interconnected circulation chambers.

[0011] Preferably, the partition is further fixed with a limit hook, the output end of which is located on the rotation path of the filter frame.

[0012] Preferably, the washing table is provided with a shaking component, which includes a rotating component, a swing rod fixedly mounted on the rotating component, and an upper swing roller and a lower swing roller rotatably mounted on the swing rod.

[0013] Preferably, the side wall of the cleaning table is provided with a clearance groove, and a floating block is slidably disposed in the clearance groove, and the end of the downward guide roller is rotatably disposed in the floating block.

[0014] Preferably, the washing station is further provided with a water squeezing assembly, which includes a splash guard, a first water squeezing roller and a second water squeezing roller rotatably disposed inside the splash guard, and a loosening groove is provided on the side wall of the splash guard, with both ends of the second water squeezing roller located in the loosening groove.

[0016] In summary, this utility model has the following beneficial technical effects:

[0017] 1. The movement of the fabric and the movement of the water are designed to be opposite, which allows some of the loose fibers inside the glutinous rice fleece to enter the water flow and be carried away by the water flow more quickly.

[0018] 2. The filter component can gather the lint in the water in the washing station, reducing the probability that lint in the water will be absorbed into the fabric. Attached Figure Description

These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive. Furthermore, the terms "first," "second," "third," and similar expressions are used for descriptive and distinguishing purposes only and should not be construed as indicating or implying the relative importance of the corresponding components.

[0026] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail.

[0027] This application discloses a pretreatment apparatus for dyeing glutinous rice wool.

[0028] A pretreatment device for dyeing glutinous rice fabric includes a washing table 1, on which a drive roller group 11 and a driven roller group 12 are arranged. Two downward guide rollers 2 are arranged at the bottom of the washing table 1, one of which is close to the drive roller group 11, and the other is close to the driven roller group 12. The glutinous rice fabric to be washed is rolled onto the driven roller group 12, and then the ends of the fabric are sequentially wrapped around the two guide rollers and onto the drive roller group 11. The drive roller group 11 rotates under the drive of a motor, thus washing the fabric within the washing table 1.

[0029] Below the downward guide roller 2 near the active roller group 11, there is a fan blade 13. There are multiple fan blades 13. The direction of the water flow stirred by the fan blades 13 is opposite to the direction of the fabric movement, thereby increasing the movement speed between the water flow and the fabric.

[0030] A filter assembly 3 is located below the driven roller group 12. The filter assembly 3 includes a filter frame 31 and a filter screen 32 detachably mounted on the filter frame 31. Rotating columns 33 are located on both sides of the filter frame 31 and are rotatably connected to the side wall of the washing table 1. The rotating columns 33 are located in the upper middle part of the filter frame 31. As the water flows, lint in the water is filtered by the filter screen. The filter frame 31 and the filter screen 32 are detachably connected, either by snap-fit ​​or simple plug-in connection; this is existing technology and will not be described in detail.

[0031] A partition 14 is horizontally installed inside the cleaning platform 1, dividing the interior of the cleaning platform 1 into two interconnected circulation chambers. As the fan blade 13 rotates, the water flows in and out of the circulation chambers. A U-shaped guide plate 15 is also fixedly installed inside the cleaning platform 1, which facilitates water circulation.

[0032] The partition 14 is also fixed with a limit hook 34, the output end of which is located in the rotation path of the filter frame 31. The flow of water can push the filter frame 31 to rotate, causing the filter screen 32 to tilt. The filter screen 32 and the flow of water form a certain angle, which facilitates water circulation and ensures the flow rate.

[0033] The washing table 1 is equipped with a shaking component 4, which includes a rotating component 41, a swing rod 42 fixedly mounted on the rotating component 41, and an upper swing roller 43 and a lower swing roller 44 rotatably mounted on the swing rod 42. The rotating component 41 can rotate under the drive of a motor. The fabric is located between the upper swing roller 43 and the lower swing roller 44. As the rotating component 41 rotates, the upper swing roller 43 and the lower swing roller 44 swing up and down. The upper swing roller 43 pushes the upper surface of the fabric, and the lower swing roller 44 pushes the lower surface of the fabric, thereby causing the fabric to move in a wave-like manner, which accelerates the removal of poor-quality lint.

[0034] The side wall of the washing station 1 is provided with a clearance groove 21, and a floating block 22 is slidably arranged in the clearance groove 21. The end of the pressure guide roller 2 is rotatably arranged in the floating block 22. As the fabric moves in a wave-like manner, the pressure guide roller 2 will also float with the floating block 22, so that the pressure roller can press the fabric into the water and reduce the impact on the fabric.

[0035] The washing station 1 is also equipped with a wringing assembly 5, which includes a splash guard 51, a first wringing roller 52 and a second wringing roller 53 rotatably disposed within the splash guard 51, and a loosening groove 54 on the side wall of the splash guard 51. The two ends of the second wringing roller 53 are located within the loosening groove 54. The fabric is located between the first wringing roller 52 and the second wringing roller 53. The loosening groove 54 allows the second wringing roller 53 to have some loosening space. Under its own weight, the second wringing roller 53 can press the fabric, squeezing out the water. Finally, the fabric is wound up by the active roller assembly 11.

[0036] The implementation principle of the embodiment is as follows: the fan blade 13 can increase the flow of water, so that the fluff can be carried away by the water flow and filtered into the filter component 3.

[0037] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the above specific embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
