When the first transmission roller 6 rotates, the first transmission roller 6 rotates to drive the first belt 9, and the first belt 9 drives the second transmission roller 7 to rotate, and the second transmission roller 7 rotates to drive the second conveyor line 5, so that the leather can enter the spraying chamber 2 through the first conveyor line 4, and the spraying assembly in the spraying chamber 2 can spray the leather. The connecting frame 33 can transfer the leather from the first conveyor line 4 to the second conveyor line 5. The second conveyor line 5 can drive the sprayed leather through the drying chamber 3, and the drying chamber 3 can dry the leather. When the leather is dried, the operator can take the leather away from the second conveyor line 5.

[0021] The spraying assembly includes a hollow rotating roller 10, a plurality of water distribution pipes 11 and a plurality of nozzles 12. The rotating roller 10 is rotatably arranged in the spraying chamber 2. The water distribution pipe 11 is conductively connected to the rotating roller 10. The nozzle 12 is conductively connected to the water distribution pipe 11 and the nozzle 12 is facing the leather. A storage tank 13 is provided on the spraying chamber 2 and the storage tank 13 is conductively connected to the rotating roller 10.

[0024] The storage tank 13 includes a tank body 20, a rotating rod 21, a stirring rod 22, a scraper rod 23, a first water pipe 24 and a first conveying pump 25. The tank body 20 is fixed on the spraying chamber 2, the rotating rod 21 is rotatably arranged in the tank body 20 and the rotating rod 21 passes through the tank body 20 and the spraying chamber 2, the stirring rod 22 is fixed on the rotating rod 21, the scraper rod 23 is fixed on the rotating rod 21 and the scraper rod 23 is in contact with the inner wall of the tank body 20, one end of the first water pipe 24 is connected to the inside of the tank body 20 and the other end of the first water pipe 24 is connected to the rotating roller 10, the first water pipe 24 is provided with a first conveying pump 25, and the rotating roller 10 and the rotating rod 21 are provided with a second belt 26.

[0025] When the rotating roller 10 rotates, the rotating roller 10 drives the second belt 26, and the second belt 26 can drive the rotating rod 21 to rotate. The rotation of the rotating rod 21 can drive the stirring rod 22 to rotate, so that the stirring rod 22 can stir the liquid in the storage tank 13 to prevent the raw materials in the liquid from settling, so that the properties of the raw materials for spraying tend to be consistent. The rotating scraper 23 can clean the inner wall of the storage tank 13, reducing the number of times the operator cleans the inner wall of the tank body 20. The raw materials in the storage tank 13 can be transported to the first water pipe 24 through the first conveying pump 25, and then transported to the rotating roller 10 through the first water pipe 24. A bearing is provided in the rotating roller 10, and the first water pipe 24 is penetrated at the center of the bearing.

[0026] The spray chamber 2 is provided with a return water trough 27 and the return water trough 27 is fixedly connected to the inner wall of the spray chamber 2, the rotating roller 10 is provided with an inclined plate 28 and the inclined plate 28 is conductively connected to the return water trough 27, a second water pipe 29 is provided in the spray chamber 2 and the second water pipe 29 is conductively connected to the return water trough 27, a second delivery pump 30 is fixedly provided in the spray chamber 2 and the second delivery pump 30 is conductively connected to the second water pipe 29, a third water pipe 31 is conductively provided on the delivery end of the second delivery pump 30 and the third water pipe 31 is conductively connected to the storage tank 13.

[0027] When the leather is sprayed in the spraying chamber 2, excess raw material liquid will drip into the spraying chamber 2. The inclined plate 28 is connected to the rotating roller 10 through a bearing. The excess liquid drips onto the inclined plate 28 and moves to the return water tank 27 by relying on the liquid's own weight. The return water tank 27 can collect the dripping liquid. Finally, the liquid in the return water tank 27 is conducted to flow into the second water pipe 29. The second delivery pump 30 can deliver the liquid in the second water pipe 29 to the storage tank 13, thereby realizing the recycling of a small amount of residual material spilled during spraying, thereby improving the environmental protection of the entire spraying process.

[0028] Heating plates 32 are fixedly mounted on both inner walls of the drying chamber 3 and the heating plates 32 are located on both sides of the second conveying line.

[0029] During the drying process, the heating plate 32 can dry the leather passing through the drying chamber 3. The heating plate 32 is a prior art and will not be elaborated on here.

[0030] Working principle:

[0031] First, the operator places the leather that needs to be sprayed on the first conveyor line 4, and then the operator starts the motor 8. The motor 8 drives the first transmission roller 6 to rotate, and the first transmission roller 6 rotates to drive the first conveyor line 4. When the first transmission roller 6 rotates, the first transmission roller 6 rotates to drive the first belt 9, and the first belt 9 drives the second transmission roller 7 to rotate, and the second transmission roller 7 rotates to drive the second conveyor line 5, so that the leather can enter the spraying chamber 2 through the first conveyor line 4.

The rotation of the first bevel gear 15 drives the second bevel gear 16 to rotate. The rotation of the second bevel gear 16 drives the rotating roller 10 to rotate. The rotation of the rotating roller 10 drives the water distribution pipe 11 to rotate. The rotation of the water distribution pipe 11 drives the nozzle 12 to rotate. The operator adds the liquid required for spraying into the storage tank 13. Since the storage tank 13 is conductively connected to the rotating roller 10, the liquid can be conducted to the water distribution pipe 11 through the rotating roller 10. The nozzle 12 can spray the leather passing through the spray chamber 2, and when the leather is sprayed, the rotating water distribution pipe 11 can expand the spraying range of the leather.

[0032] When the rotating roller 10 rotates, the rotating roller 10 drives the second belt 26, and the second belt 26 can drive the rotating rod 21 to rotate. The rotation of the rotating rod 21 can drive the stirring rod 22 to rotate, so that the stirring rod 22 can stir the liquid in the storage tank 13 to prevent the raw materials in the liquid from settling, so that the properties of the raw materials for spraying tend to be consistent. The rotating scraper 23 can clean the inner wall of the storage tank 13, reducing the number of times the operator cleans the inner wall of the tank body 20. The raw materials in the storage tank 13 can be transported to the first water pipe 24 through the first conveying pump 25, and then transported to the rotating roller 10 through the first water pipe 24. A bearing is provided in the rotating roller 10, and the first water pipe 24 is penetrated at the center of the bearing.

[0033] When the leather is sprayed in the spraying chamber 2, excess raw material liquid will drip into the spraying chamber 2.

The excess liquid drips onto the inclined plate 28 and moves to the return water tank 27 by relying on the liquid's own weight. The return water tank 27 can collect the dripping liquid. Finally, the liquid in the return water tank 27 is conducted to flow into the second water pipe 29. The second delivery pump 30 can deliver the liquid in the second water pipe 29 to the storage tank 13, thereby realizing the recycling of a small amount of residual material spilled during spraying, thereby improving the environmental protection of the entire spraying process.

[0034] The connecting frame 33 can transfer the leather from the first conveyor line 4 to the second conveyor line 5. The second conveyor line 5 can drive the leather that has been sprayed to pass through the drying chamber 3. During the drying process, the heating plate 32 inside can dry the leather passing through the drying chamber 3.

[0035] When the leather is dried, the operator can take the leather away from the second conveyor line 5.
