[0022] The second cleaning mechanism 6 includes compression capsules 601 uniformly and fixedly connected to both sides of the slide rail 4.

The magnetic poles between the semi-circular magnetic ring 602 and the arc-shaped cleaning plate 603 are opposite. The area of the connecting disk 604 is smaller than the area of the semi-circular opening. One end of the arc-shaped cleaning plate 603 away from the connecting disk 604 tilts outward. The second cleaning mechanism 6 further includes second cleaning blocks 608 arranged on both sides of the slide rail 4. The bottom end of the second cleaning block 608 on the side of the slide rail 4 away from the sliding device 3 is fixedly connected to the frame 1. The second cleaning block 608 on the side of the slide rail 4 close to the sliding device 3 is fixedly connected to the strip-shaped groove. A rectangular opening is provided near the bottom end. A second rectangular opening is provided in the middle of the rectangular opening. An arc-shaped convex block 610 is fixedly connected to the right side of the second rectangular opening. Magnetic strips 609 are fixedly connected to the parts of the rectangular opening at the top and bottom of the second rectangular opening. The top end of the second cleaning block 608 on the side of the slide rail 4 away from the sliding device 3 is rotatably connected to the pulley 301. The magnetic poles of the end of the compression capsule 601 away from the slide rail 4 and the magnetic strip 609 are the same.

[0023] During use, when the sliding device 3 is started to drive the handling device 302 to move through the pulley 301 to move the container, the sliding device 3 slides on the slide rail 4, drives the connecting piece 501 to move through the pulley 301, and at the same time starts the water supply device 502 to inject water into the connecting water tank 504 through the conduit. During the process of the connecting piece 501 driving the water supply device 502 and the connecting block 505 to move, the water flowing into the connecting water tank 504 enters the connecting water guide piece 514 and the limiting elastic bag 508 through the telescopic water pipe in the limiting spring 506, causing the limiting elastic bag 508 to extend downward by a certain length, pushing the cleaning block 509, the arc-shaped cleaning block 510 and the cleaning brush 511 closer to the inner surface of the slide rail 4. Under the action of the connecting piece 501 driving the connecting block 505 to move, the cleaning brush 511 is driven to clean the inner surface of the slide rail 4. At the same time, during the movement of the connecting block 505, a current is intermittently passed into the limiting spring 506 for a period of time. After the limiting spring 506 is electrified, the coils of the limiting spring 506 contract due to the mutual attraction of the current, driving the connecting block 505 to move. When the limiting spring 506 contracts, it drives the telescopic water pipe to contract, reducing the space in the telescopic water pipe, so that the water in the telescopic water pipe is squeezed into the limiting elastic bag 508 through the connecting water guide piece 514, causing the limiting elastic bag 508 to further push the cleaning block 509, the arc-shaped cleaning block 510 and the cleaning brush 511 to closely adhere to the surface of the slide rail 4 to clean the surface of the slide rail 4, enhancing the cleaning effect on the surface of the slide rail 4. When the current is passed into the limiting spring 506 for a period of time and then stopped, the limiting spring 506 is pushed to reset by its own elasticity, so that the connecting block 505 can continuously move left and right during the movement process, increasing the friction frequency between the cleaning brush 511 and the surface of the slide rail 4, and further enhancing the cleaning effect on the surface of the slide rail 4. After cleaning the surface of the slide rail 4 for a period of time, the magnitude of the current passed into the limiting spring 506 is increased to completely contract the limiting spring 506 and further compress the telescopic water pipe, increasing the pressure in the limiting elastic bag 508. At this time, the automatic pressure sensing valve opens, and the water in the connecting block 505, the connecting water tank 504, the limiting elastic bag 508 and the connecting water guide piece 514 is sprayed out through the arc-shaped spray nozzle 512 and the spray nozzle 513, flushing the dust cleaned from the slide rail 4 and the dust on the cleaning brush 511, and making the water entering the slide rail 4 drive the dust to flow out through the semi-circular opening on the slide rail 4, preventing dust from accumulating in the slide rail 4.

[0024] During the movement of the pulley 301, the second cleaning block 608 is driven to move. During the movement of the second cleaning block 608, the magnetic strip 609 and the arc-shaped convex block 610 are driven to move. When the magnetic strip 609 passes by the compression capsule 601, the compression capsule 601 moves towards the side close to the slide rail 4 under the action of magnetic repulsion between the compression capsule 601 and the magnetic strip 609 to compress the air in the compression capsule 601. At the same time, when the arc-shaped convex block 610 passes by the end of the moving rod 605 far from the slide rail 4, the arc-shaped convex block 610 squeezes the moving rod 605, causing the moving rod 605 to push the arc-shaped cleaning plate 603 towards the semi-circular magnetic ring 602 and the semi-circular opening and stretch the connecting spring 607. When the arc-shaped cleaning plate 603 completely enters the semi-circular magnetic ring 602, an electric current is passed into the semi-circular magnetic ring 602, causing the arc-shaped cleaning plate 603 to move towards the side where the inner wall of the semi-circular magnetic ring 602 is located under the action of the magnetism of the semi-circular magnetic ring 602, so that the upturned end of the arc-shaped cleaning plate 603 is closely attached to the inner wall of the semi-circular magnetic ring 602 and the semi-circular opening. When the arc-shaped convex block 610 moves away from the moving rod 605, the moving rod 605 is driven by the connecting spring 607 to reset, and a collision occurs between the connecting disk 604 and the fixed frame 606. Under the action of inertia, the arc-shaped cleaning plate 603 is scraped off from the inner walls of the semi-circular opening and the semi-circular magnetic ring 602, and the dust is taken out from the semi-circular opening and the semi-circular magnetic ring 602. And when the arc-shaped convex block 610 moves away from the moving rod 605, the electric current is stopped from being passed into the end of the compression capsule 601 far from the slide rail 4, so that the compression capsule 601 quickly resets, driving the connecting spring 607 to elongate and taking the arc-shaped cleaning plate 603 out of the semi-circular magnetic ring 602 and the semi-circular opening, further improving the cleaning effect on the dust in the semi-circular opening.
