[0040] With the above solution: By setting the two exhaust fans 13, the placement box 14, the air pipe 15 and the plug cover 16, when not exhausting, the air pipe 15 is blocked by the plug cover 16. When in use, the plug cover 16 is pulled out. By starting the two exhaust fans 13, the hot air inside the drying box 3 can be discharged through the air pipe 15.
[0041] Reference Figure 6 , a plurality of water channels 17 are opened at the top inside the detachable plate 12 and are evenly distributed at the top inside the detachable plate 12, which are used to flow the coating agent through the plurality of water channels 17 into the inside of the base 201. Multiple cold-rolled plates 23 can be placed on the top of the detachable plate 12. A plurality of funnel openings 18 are opened at the top inside the detachable plate 12 and are evenly distributed at the top inside the detachable plate 12, which are used to circulate the coating agent.
[0042] With the above solution: By setting the plurality of water channels 17 and the plurality of funnel openings 18, the coating agent is sprayed downward by the spraying assembly 9. The coating agent is sprayed onto the top of the detachable plate 12, so as to coat the cold-rolled plate 23. The excess coating agent can flow through the plurality of water channels 17 and the plurality of funnel openings 18 to the lower part of the detachable plate 12, and thus can be discharged from the discharge port 11.
[0043] Reference Figure 1, a vibration motor 19 is fixedly connected to the right side of the water washing tank 1. The vibration frequency of the vibration motor 19 is adjusted through a controller, which is used to vibrate the water washing tank 1 and make the rack 501 inside the placement tank 4 vibrate to perform vibration cleaning on the cold-rolled plate 23.
[0044] Adopting the above solution: By setting the vibration motor 19, the water washing tank 1 is vibrated through the vibrator. The vibration of the water washing tank 1 will cause the rack 501 to vibrate, and the rack 501 will cause the pure water inside to vibrate, so as to clean the cold-rolled plate 23 by vibrating the pure water.
[0045] Reference Figure 3 , a circular ring 20 is fixedly connected inside the water tank 804. On the left and right sides inside the circular ring 20, circular holes 21 are fixedly connected. Plug-in connections of cylinders 22 are made inside the two circular holes 21. The tops of the two cylinders 22 are fixedly connected to the bottom of the filter cotton 805.
[0046] Adopting the above solution: By setting the circular ring 20, the two circular holes 21 and the two cylinders 22, the circular ring 20 plays a supporting role.

[0047] The working principle of the present invention:
[0048] In use, multiple cold-rolled plates 23 are inserted into the interior of the rack 501. The cold-rolled plates 23 are partitioned by multiple partitioning blocks 504. Then, pure water is poured into the interior of the rack 501, and the vibration motor 19 is started. The vibration motor 19 causes the water washing tank 1 to vibrate, and the water washing tank 1 causes the rack 501 to vibrate, so that the pure water in the rack 501 vibrates to clean the multiple cold-rolled plates 23. After cleaning, by opening the water valve 7, the pure water flows through the water valve 7 into the interior of the ultrafiltration membrane tube 802. The ultrafiltration membrane tube 802 filters the pure water for the first time. The pressure valve 803 is opened to make the pure water inside the ultrafiltration membrane tube 802 flow into the interior of the water tank 804. The filter cotton 805 filters the pure water for the second time. When coating the multiple cold-rolled plates 23, the multiple cold-rolled plates 23 are placed on the top of the detachable plate 12. By starting the four hydraulic columns 203, the square plate 10 is driven to move downward, and the medicine tank 903, three pipes 901, three spray pipes 902 and multiple diffusion-shaped nozzles 904 are also moved downward. The coating agent inside the medicine tank 903 is diffused and sprayed downward from the three spray pipes 902 through the multiple diffusion-shaped nozzles 904, so as to be sprayed onto the surfaces of the multiple cold-rolled plates 23. When the back needs to be sprayed, the multiple cold-rolled plates 23 are turned over. The sprayed coating agent flows through the multiple water channels 17 and multiple funnel openings 18 to the bottom of the detachable plate 12, so that the excess coating agent or the water inside the cleaning base 201 flows out from the discharge port 11. The multiple coated cold-rolled plates 23 are placed inside the drying oven 3 for drying. After long-term use of the drying oven 3, the coating agent will produce an odor after long-term drying. After pulling out the plugging cover 16, the two exhaust fans 13 are turned on, and the two exhaust fans 13 discharge the hot air inside the drying oven 3 through the air pipe 15.
