[0033] like Figure 2 As shown, the leather conveying assembly 1 specifically includes two frames 11, a square frame 12 fixedly connected to the top of the frame 11, and a plate conveyor belt 13 rotatably disposed in the inner cavity of the square frame 12. Several rotating rollers located in the inner circle of the plate conveyor belt 13 are rotatably connected inside the square frame 12, as well as a drive roller. A drive motor 14 is installed on the left side surface of the square frame 12, and the output shaft of the drive motor 14 is connected to the end of the drive roller through a coupling.

[0034] like Figure 3 As shown, the leather clamping assembly 2 specifically includes a base 21, a hollow tube 24 fixed to the top of the base 21, and a movable rod 22 that runs horizontally through the hollow tube 24. A fastening screw 23 runs through the top of the hollow tube 24, and metal clips 25 are fixedly connected to the ends of the movable rods 22 that are close to each other.

[0035] like Figure 4As shown, the spray-type flushing assembly 3 specifically includes a water tank 31, a water pump 33 located above the water tank 31, a suction port of the water pump 33 connected to a suction pipe 32 that penetrates into the inner cavity of the water tank 31, a discharge port of the water pump 33 connected to a discharge pipe 34 located above the plate conveyor belt 13, and 7-9 nozzles 35 installed through the bottom surface of the discharge pipe 34.

[0036] like Figure 5 As shown, the leather dirt softening component 4 specifically includes a steam heat source 41 and a steam conveying pipe 42 connected to the steam conveying port of the steam heat source 41. The steam conveying pipe 42 is located above the plate conveyor belt 13.

[0037] Specifically, in this embodiment, the leather clamping components 2 are arranged in a mirror-symmetrical manner with the central axis of the plate conveyor belt 13 as the reference line, and the bottom surface of the base 21 is fixedly connected to the top surface of the plate conveyor belt 13.

[0038] More specifically, the hollow tube 24 has a through hole that runs from left to right for the movable rod 22 to pass through; the top of the hollow tube 24 has a threaded hole for the fastening screw 23 to pass through. The bottom end of the fastening screw 23 located in the inner cavity of the hollow tube 24 is in close contact with the outer ring surface of the movable rod 22, and the metal clip 25 is clamped on the surface of the leather with its clamping jaw away from the movable rod 22.

[0039] Meanwhile, the top surface of the water tank 31 is provided with a liquid replenishment port, and the top surface of the water tank 31 is provided with a round hole for the liquid extraction pipe 32 to pass through.

[0041] When using this pneumatic leather cleaning device, the metal clamps 25 are first clamped onto the four corners of the leather. After pulling the movable rod 22 outward, the locking screw 23 is tightened to tighten the leather, ensuring that there is a gap of more than 5 cm between the leather and the upper surface of the plate conveyor belt 13. Then, the drive motor 14 drives the drive roller to rotate, thereby driving the plate conveyor belt 13 to rotate slowly. Afterward, the steam heat source 41 provides steam into the steam delivery pipe 42. The fine holes on the lower surface of the steam delivery pipe 42 allow the steam to be sprayed onto the surface of the leather. Under the combined action of the steam temperature and water vapor, the dirt on the surface of the leather is softened. During the continued transportation of the leather, the water pump 33 draws pure water from the water tank 31 through the liquid extraction pipe 32 and delivers the pure water to the nozzle 35 through the liquid discharge pipe 34. The nozzle 35 sprays water onto the leather, using the impact force of the water flow to wash away the softened dirt.
