Description

Technical Field

[0001] This utility model belongs to the field of microfiber leather processing technology, specifically relating to a high-efficiency water washing device for microfiber leather with brush bristles. Background Technology

[0002] In the production of microfiber leather, after the base fabric is dyed, the product needs to be thoroughly rinsed to remove any remaining unfixed dye, auxiliaries, acids, alkalis, salts, etc., and to remove unfixed dyes and chemicals from within the fibers in order to obtain good color fixation and stable color. Previously, a submersible rolling mill was used. This mill, submerged in the cleaning solution, pressed the solvent out of the leather fibers. After rolling, the cleaning solution was drawn back into the leather fibers, and the rolling process was repeated to achieve thorough cleaning of the microfiber leather. This cleaning method is obviously ineffective, requires a large number of submersible rolling mills, and has low cleaning efficiency. Utility Model Content

[0003] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a high-efficiency water washing device for microfiber leather with brush bristles, including a water washing tank, a front brush wheel, a back brush wheel, several soaking rollers, a pressing device, and several guide rollers installed in the water washing tank. One side of the water washing tank is set as the inlet and the other side is set as the outlet. The soaking rollers are set below the liquid surface in the water washing tank. The circumferential surfaces of the front brush wheel and the back brush wheel are respectively covered with bristles. Both the front brush wheel and the back brush wheel are located above the liquid surface in the water washing tank. The front brush wheel and the back brush wheel are driven to rotate by motors. The pressing device includes a lower pressing roller and an upper pressing roller located above the lower pressing roller. The upper pressing roller is kept in a state of pressing the lower pressing roller by a compression spring. The lower pressing roller and the upper pressing roller are rotatably installed at the outlet.

[0004] As a preferred embodiment of the above technical solution, a front adjusting roller and a back adjusting roller are installed above the washing tank.

[0012] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0013] like Figure 1 As shown, a high-efficiency microfiber leather washing device with brush bristles includes a washing tank 1. The washing tank 1 is equipped with a front brush wheel 2, a back brush wheel 3, several soaking rollers 4, a pressing device, and several guide rollers 5. One side of the washing tank 1 is a fabric inlet 6, and the other side is a fabric outlet 7. The soaking rollers 4 are positioned below the liquid surface in the washing tank 1. The circumferential surfaces of the front brush wheel 2 and the back brush wheel 3 are respectively covered with brush bristles 8. Both the front brush wheel 2 and the back brush wheel 3 are located above the liquid surface in the washing tank 1. The front brush wheel 2 and the back brush wheel 3 are driven to rotate by motors 9. The pressing device includes a lower pressing roller 10 and an upper pressing roller 11 located above the lower pressing roller 10. The upper pressing roller 11 is kept pressing the lower pressing roller 10 by a compression spring. The lower pressing roller 10 and the upper pressing roller 11 are rotatably mounted at the fabric outlet 7. Microfiber leather 22 enters the washing tank 1 through the inlet 6 via guide roller 5, and is repeatedly submerged below the liquid surface by the dipping roller 4. After leaving the liquid surface, the microfiber leather 22 is brushed on the front side by the front brush wheel 2 and on the back side by the back brush wheel 3, which mechanically removes some insoluble dye particles or aggregates from the fibers and PU surface and disperses them into the washing solution. Then, the microfiber leather 22 re-enters the liquid surface and finally passes between the lower pressure roller 10 and the upper pressure roller 11, where the pressure between them squeezes out the cleaning solution from the microfiber leather 22. The squeezed-out cleaning solution returns to the washing tank 1. The microfiber leather 22 then proceeds to the next processing step or enters the next washing tank 1 for repeated cleaning.

[0014] Furthermore, a front adjusting roller 12 and a back adjusting roller 13 are installed above the washing tank 1. The front adjusting roller 12 is rotatably mounted on a first sliding frame 14, which is driven by a first cylinder 15 to move horizontally toward the front brushing wheel 2. The back adjusting roller 13 is rotatably mounted on a second sliding frame 16, which is driven by a second cylinder 17 to move horizontally toward the back brushing wheel 3. The first cylinder 15 drives the first sliding frame 14 to move, changing the position of the front adjusting roller 12 and pressing the microfiber leather 22 toward or away from the front brushing wheel 2, thereby changing the contact area between the front of the microfiber leather 22 and the front brushing wheel 2. The second cylinder 17 drives the second sliding frame 16 to move, causing the back adjusting roller 13 to press toward or away from the back brushing wheel 3, thereby changing the contact area between the back brushing wheel 3 and the back of the microfiber leather 22.

[0015] Furthermore, each end of the upper pressure roller 11 is rotatably connected to a slider, which is slidably mounted on a vertical slide rail. The lower end of the pressure spring is fixedly connected to the slider, and the upper end of the pressure spring is provided with an adjusting bolt, which is threadedly connected to a fixing plate. By rotating the adjusting bolt, the elastic force of the pressure spring can be changed, thereby adjusting the pressure of the pressing device on the microfiber leather 22.

[0016] Furthermore, a tension adjusting roller 18 is installed inside the washing tank 1. The tension adjusting roller 18 is rotatably mounted on a swing arm 19, which is rotatably mounted on the washing tank 1 via a rotating shaft 21. A torsion spring is fitted onto the rotating shaft 21, with one end of the torsion spring fixedly connected to the washing tank 1 and the other end fixedly connected to the rotating shaft 21. The tension adjusting roller 18 swings up and down according to the tension of the microfiber leather 22. The tension adjusting roller 18 adjusts the tension of the microfiber leather 22 to prevent the tension of the microfiber leather 22 from being too high or too low.

[0017] Furthermore, limit rods 20 are provided on both sides of the swing arm 19.

[0018] It is worth mentioning that the technical features such as tension adjusting roller, motor, and cylinder involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0019] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
