[0032] The outer wall of the fixing mechanism 2 is provided with a frame 1, and the frame 1 includes a base plate 101. The outer wall of the base plate 101 is fixedly connected with multiple groups of support columns 103, and the multiple groups of support columns 103 are slidably connected with a sliding frame 104. The top of the sliding frame 104 is fixedly connected with multiple groups of return springs 105, and the top of the return spring 105 is fixedly connected to the inner wall of the support column 103. The top of the base plate 101 is fixedly connected with a guide rail 102, and the top of the guide rail 102 is provided with multiple groups of rollers 106, and the multiple groups of rollers 106 are rotatably connected to the side wall of the fixing plate 201.

[0033] By lifting the handle 202 and pulling it, the fixed plate 201 drives the roller 106 to roll on the top of the guide rail 102, so that the roller 106 at one end of the fixed plate 201 is separated from the guide rail 102, and then the lower fixed plate 201 supports the support rod 203 on the ground, so that the two sets of rollers 106 at the other end of the fixed plate 201 slide to one end of the guide rail 102, and then the cowhide is spread on the top of the fixed plate 201, and then the cowhide is lifted up so that the cowhide is pierced by the spikes 211, and then the bidirectional threaded rod 208 is rotated so that the bidirectional threaded rod 208 is The pattern rod 208 drives the two groups of adjustment blocks 207 to move away from each other, and then the two groups of adjustment blocks 207 push the multiple groups of connecting rods 206 respectively, thereby pushing the two groups of connecting frames 205 to move away from each other. During the movement of the connecting frame 205, the pull rod 209 is driven to slide on the inner wall of the guide frame 204, so that the pull rod 209 drives the spikes 211 to move through the pressing head 210, so that the multiple groups of spikes 211 tighten and stretch the cowhide, and then hold the handle 202 to lift one end of the fixed plate 201, and then push the fixed plate 201 back to its original position, so that the fixed plate 201 is in Figure 2 In the state, during the process of pulling and pushing the fixed plate 201, the edge of the fixed plate 201 is tilted upward, so that the sliding frame 104 is pushed by the fixed plate 201, so that the sliding frame 104 slides upward and compresses the reset spring 105. After the fixed plate 201 returns to its original position, the rebound force of the reset spring 105 pushes the sliding frame 104 to reset, so that the spraying mechanism 3 can keep in contact with the surface of the cowhide.

A sliding rod 302 is fixedly connected between multiple groups of hydraulic rods 301, and multiple groups of nozzles 303 are fixedly connected to the bottom of the sliding rod 302. A suction port 304 located next to the nozzle 303 is opened at the bottom of the sliding rod 302. A rubber strip 305 is fixedly connected to the bottom of the nozzle 303. The rubber strip 305 is located next to the suction port 304. The top of the suction port 304 is connected to multiple groups of connecting pipes 306. The top is connected to a filter bin 307, which is fixedly connected to the top of the sliding frame 104. The inner wall of the filter bin 307 is fixedly connected to multiple sets of fans 308 at the connection point with the connecting pipe 306. The side wall of the filter bin 307 is slidably connected to a filter plate 309. Two sets of limit blocks 310 are fixedly connected on both sides of the filter bin 307. The inner wall of each set of limit blocks 310 is slidably connected to a set of limit pins 311. One end of the limit pin 311 located inside the limit block 310 is fixedly connected to a limit spring 312, and the end of the limit spring 312 is fixedly connected to the inner wall of the limit block 310.

[0035] The fan 308 drives the air flow to pass through the filter plate 309, so that negative pressure is generated at the suction port 304, so that the dust on the surface of the cowhide is taken away by the air flow and enters the filter bin 307. The air flow passes through the filter plate 309 so that the dust is filtered out by the filter plate 309. The side wall of the sliding rod 302 is provided with a connection port connected to the liquid pump, so that the solvent can be pumped into the sliding rod 302 and sprayed from the nozzle 303, so as to spray the cowhide surface finely. By pushing the limit pin 311, The limit pin 311 compresses the reset spring 105, so that the limit pin 311 is separated from the filter plate 309, and then the filter plate 309 is pulled to separate the filter plate 309 from the filter chamber 307, and then the new filter plate 309 is attached to the side wall of the filter chamber 307, and then the limit pin 311 is released, so that the limit pin 311 is reset under the rebound of the reset spring 105, so that the limit pin 311 is attached to the side wall of the filter plate 309, and the filter plate 309 is fixed to the side wall of the filter chamber 307.

[0036] When in use, the spikes 211 are inserted into the cowhide, and then the bidirectional threaded rod 208 is rotated to make the adjustment block 207 push the connecting rod 206, so that the connecting frame 205 drives the pull rod 209 to move, and the pull rod 209 drives the pressure head 210 to move to both sides, so that the spikes 211 move to both sides, so that the cowhide is pulled to both sides, and the cowhide is in a taut and flat state, thereby ensuring that when the cowhide surface is sprayed, the waterproof and anti-fouling solvent can be sprayed on the cowhide surface more evenly and fully, avoiding the presence of unsprayed areas on the cowhide surface. The parts not involved in the device are the same as the prior art or can be implemented by the prior art.
