A cleaning mechanism is arranged in the interior of the tank body 1, and the coating attached to the inner wall of the tank body 1 can be scraped and removed during the working process through the cleaning mechanism. The cleaning mechanism includes a rotating rod 10, a cleaning scraping block 11, a connecting groove 12, a connecting block 13, a sliding groove 14, a sliding block 15, a spring 16, a control groove 17, a control block 18 and a limiting groove 19.

[0031] Further, the rotating rod 10 is arranged in the interior of the tank body 1, the rear side of the rotating rod 10 is fixedly connected to the outer surface of the rotating shaft 7, the cleaning scraping block 11 is arranged on the front side of the rotating rod 10, the cleaning scraping block 11 is in contact with the interior of the tank body 1, the connecting groove 12 is opened on the upper side of the rotating rod 10, the connecting block 13 is arranged in the connecting groove 12, the front side of the connecting block 13 is fixedly connected to the rear side of the cleaning scraping block 11, the sliding groove 14 is opened in the connecting block 13, the rear wall of the sliding groove 14 extends out of the connecting block 13, the sliding groove 14 is a cross-shaped groove, the sliding block 15 is slidably connected in the connecting block 13, the sliding block 15 is a cross-shaped block, the spring 16 is fixedly connected to the front side of the sliding block 15, and the front end of the spring 16 is fixedly connected to the front wall of the sliding groove 14.

[0032] Further, when starting work, first add paint into the interior of the tank body 1 through the adding port 4, and at the same time push the rotating rod 10 to make it rotate, so that when adding paint into the interior of the tank body 1, it will not pour onto the rotating rod 10. Then, spray the paint onto the surface of the lithium battery through the discharge pipe 2 and the spraying nozzle 3. At the same time, move the rotating rod 10 to the position of the adding port 4. Then, put the cleaning scraping block 11 into the interior of the tank body 1. At this time, the front side of the cleaning scraping block 11 is in contact with the inner wall of the tank body 1. Then, pull the control block 18 forward. The control block 18 drives the sliding block 15 to move into the interior of the sliding groove 14. At this time, the spring 16 starts to be compressed. Then, put the connecting block 13 into the connecting groove 12. Then, release the control block 18. Then, the spring 16 starts to reset from the compressed state, pushing the sliding block 15 to reset synchronously. The sliding block 15 drives the control block 18 to reset synchronously. After the sliding block 15 resets, a part of its rear side will move into the limiting groove 19. Then, the limiting groove 19 will limit and fix the matching sliding block 15. Then, the rotating rod 10 will limit the connecting block 13, and thus limit and fix the cleaning scraping block 11.

[0033] At the same time, the top wall and the bottom wall of the tank body 1 will also limit the cleaning scraping block 11. Then, start the slow-speed motor assembly 5. The slow-speed motor assembly 5 transmits power from the output end, driving the transmission shaft 6 to rotate. Then, the transmission shaft 6 drives the rotating shaft 7 to rotate synchronously. The rotating shaft 7 drives the rotating rod 10 to rotate synchronously. Since the rotating rod 10 is limited and clamped with the connecting block 13, the rotating rod 10 will drive the cleaning scraping block 11 to rotate synchronously. Then, during the rotation of the cleaning scraping block 11, it will scrape and clean the inner wall of the tank body 1. When it is necessary to clean the cleaning scraping block 11, rotate the rotating rod 10 to the position of the adding port 4. Then, the cleaning scraping block 11 can be removed for cleaning according to the above method. At the same time, during the working process, the rotating shaft 7 will drive the limiting ring 9 to rotate synchronously. The limiting ring 9 is limited to rotate inside the fixing groove 8. Since the limiting ring 9 is fixedly sleeved on the outer surface of the rotating shaft 7, the working stability of the rotating shaft 7 will be further improved. Then, the working stability of the cleaning scraping block 11 will also be improved. By this means, the paint attached to the inner wall of the tank body 1 can be scraped off during the working process, making the cleaning of the tank body 1 convenient. At the same time, it also avoids the decrease of the overall capacity and improves the convenience of using the paint equipment.

[0034] Working principle: When starting to work, first add paint into the interior of the tank body 1 through the adding port 4, and at the same time push the rotating rod 10 to make it rotate, so that when adding paint into the interior of the tank body 1, it will not pour onto the rotating rod 10. Then, spray the paint onto the surface of the lithium battery through the discharge pipe 2 and the spraying nozzle 3. At the same time, move the rotating rod 10 to the position of the adding port 4. Then, put the cleaning scraping block 11 into the interior of the tank body 1. At this time, the front side of the cleaning scraping block 11 is in contact with the inner wall of the tank body 1. Then, pull the control block 18 forward. The control block 18 drives the sliding block 15 to move into the interior of the sliding groove 14. At this time, the spring 16 starts to be in a compressed state. Then, put the connecting block 13 into the connecting groove 12. Then, release the control block 18. Then, the spring 16 starts to reset from the compressed state, pushing the sliding block 15 to reset synchronously. The sliding block 15 drives the control block 18 to reset synchronously. After the sliding block 15 resets, a part of its rear side will move into the limiting groove 19. Then, the limiting groove 19 will limit and fix the matching sliding block 15. Then, the rotating rod 10 will limit the connecting block 13, and thus the cleaning scraping block 11 is limited and fixed.

[0035] At the same time, the top wall and the bottom wall of the tank body 1 will also limit the cleaning scraping block 11. Then, start the slow-speed motor assembly 5. The slow-speed motor assembly 5 transmits power from the output end, driving the transmission shaft 6 to rotate. Then, the transmission shaft 6 drives the rotating shaft 7 to rotate synchronously. The rotating shaft 7 drives the rotating rod 10 to rotate synchronously. Because the rotating rod 10 is limited and clamped with the connecting block 13, the rotating rod 10 will drive the cleaning scraping block 11 to rotate synchronously. Then, during the rotation of the cleaning scraping block 11, it will scrape and clean the inner wall of the tank body 1. When it is necessary to clean the cleaning scraping block 11, rotate the rotating rod 10 to the position of the adding port 4. Then, the cleaning scraping block 11 can be removed for cleaning according to the above method. At the same time, during the working process, the rotating shaft 7 will drive the limiting ring 9 to rotate synchronously. The limiting ring 9 will be limited in the fixed groove 8 to rotate. Because the limiting ring 9 is fixedly sleeved on the outer surface of the rotating shaft 7, the working stability of the rotating shaft 7 will be further improved, and thus the working stability of the cleaning scraping block 11 will also be improved.
