[0034] Example Two

[0035] Please refer to Figure 5 , and further obtain the extrusion mechanism 4 on the basis of Example One.

[0036] The extrusion mechanism 4 comprises a second fixing frame 41 fixedly connected to the top left side of the base 1, first extrusion rollers 42 rotatably connected to the inner wall of the second fixing frame 41 on the front and back sides, a hydraulic cylinder 43 fixedly connected to the top of the second fixing frame 41, a lifting frame 44 fixedly connected to the output end of the hydraulic cylinder 43, second extrusion rollers 45 rotatably connected to the inner wall of the lifting frame 44 on the front and back sides, and guide rods 46 fixedly connected to the top of the lifting frame 44 in a symmetrical manner.

[0038] In actual operation, when the device is used, before using the leather surface treatment cleaning device, the appropriate amount of cleaning water is injected into the water tank 32 through the water injection pipe 33. When ready, turn on the power, start the water pump 34 and the servo motor 312, and adjust the initial position of the hydraulic cylinder 43 according to the material and stain of the leather to be cleaned, so that the extrusion mechanism 4 is in the appropriate working state. At this time, the whole device starts the working process, starts the water pump 34, and the water pump 34 starts to extract the cleaning water in the water tank 32 through the water inlet pipe 35. The water inlet pipe 35 penetrates the matching hole opened on the top of the water tank 32 and is fixedly connected, and the bottom end is close to the inner wall of the water tank 32. The cleaning water is pressurized by the water pump 34 and delivered to the five-way pipe connector 37 through the water outlet pipe 36. The five-way pipe connector 37 divides the cleaning water into four connecting water pipes 38, which are symmetrically distributed above and below in the first fixed frame 31, and the connecting water pipe 38 surface penetrates the matching hole opened on the front of the first fixed frame 31 and is fixedly connected, and the rear end is fixedly connected to the inner wall of the first fixed frame 31. The water spray head 39 fixed on the surface of the connecting water pipe 38 is oppositely distributed, which can quickly wet the leather and the dirt on the surface, creating favorable conditions for subsequent brushing work. The servo motor 312 starts, and the output end fixedly connected with the first brush roller 313 starts to rotate. The first fixed frame 31 is provided with holes matched with the first brush roller 313 and the second brush roller 314 on the upper and lower sides of the back surface, and the surfaces of the first brush roller 313 and the second brush roller 314 are respectively penetrated and rotatably connected in the corresponding holes. Because the first gear 315 fixedly connected to the surface of the first brush roller 313 near the rear end is engaged with the second gear 316 fixedly connected to the surface of the second brush roller 314 near the rear end, when the first brush roller 313 rotates, the second brush roller 314 is driven to rotate synchronously through gear transmission, and the rotating directions of the two are opposite. In this way, the first brush roller 313 and the second brush roller 314 simultaneously brush the leather surface from different height positions of the leather. During rotation, the brush is in full contact with the wet leather surface, and the dirt is stripped from the leather surface by using friction force, realizing deep cleaning of the leather surface. By controlling the rotating speed of the servo motor 312, the rotating speed of the brush roller can be adjusted according to the material and stain degree of the leather, and the brushing force can be controlled to achieve the best cleaning effect. After the cleaning mechanism 3 completes the cleaning of the leather, the remaining dirt on the surface of the leather is washed through the two groups of connecting water pipes 38 and water spray heads 39 on the left side, and then the leather enters the extrusion mechanism 4. At this time, according to the thickness of the leather and the required extrusion degree, the height of the lifting frame 44 is adjusted by controlling the hydraulic cylinder 43. The hydraulic cylinder 43 is fixed on the top of the second fixed frame 41, and the output end is connected with the lifting frame 44.The guide rods 46 are symmetrically fixed on the top of the lifting frame 44, penetrate the matching holes on the top of the second fixed frame 41 and are connected with the second fixed frame 41 in a sliding mode, the two guide rods 46 can support and guide the lifting frame 44, so that the lifting frame 44 can move up and down steadily under the drive of the hydraulic cylinder 43, thereby the distance between the second extrusion roller 45 and the first extrusion roller 42 can be adjusted accurately, and the subsequent extrusion work can be prepared, when the distance between the second extrusion roller 45 and the first extrusion roller 42 is adjusted, the cleaned leather is conveyed between the two extrusion rollers. The first extrusion roller 42 is rotatably connected to the inner wall of the second fixed frame 41, and the second extrusion roller 45 is rotatably connected to the inner wall of the lifting frame 44 and is located above the first extrusion roller 42. With the movement of the leather, the two extrusion rollers can apply pressure to the leather and squeeze out the excess water absorbed in the leather.
