[0036] Reference Figure 6 A groove 12 is provided at one end of the first rotating rod 6, and the groove 12 is used in conjunction with the rotating ball 11; by providing the groove 12, the rotating ball 11 can be connected, and a rotating space is provided for the rotating ball 11 in the first rotating rod 6, thereby improving the flexibility of the connection.

[0037] Working principle: When the user starts the first motor 2 through the external control switch, the first motor 2 is powered by an external power supply, and the output end of the first motor 2 drives the first rotating rod 6 to rotate, the first rotating rod 6 can drive the screen drum 5 to rotate, and the battery materials are screened. Some sticky materials will adhere to the inner wall of the screen drum 5 and the screen. At this time, the user starts the second motor 301, and the second motor 301 drives the second rotating rod 302 to rotate, and the connecting rod 10 and the rotating ball 11 rotate in the groove 12 of the first rotating rod 6. The first rotating rod 6 and the second rotating rod 302 can be connected without affecting their respective operations. When the second rotating rod 302 rotates, the inner ring of the bearing 303 rotates with the second rotating rod 302, and the support rod 304 can be connected through the outer ring of the bearing 303. The support rod 304 can fix the brush 305. Because the bristles of the brush 305 are long, they can enter the inner wall of the screen of the screen drum 5. The brush 305 can be limited by the limiting rod 307 and the limiting block 7, so that the bristles of the brush 305 can be aligned with the inner wall of the screen drum 5. When the screen drum 5 rotates, the limit rod 307 and the limit block 7 will move along the path of the slide slot 306, driving the brush 305 to move back and forth, so that the bristles of the brush 305 can enter the inner wall of the screen, and clean the battery materials adhered to the inner wall of the screen. The ball 8 can reduce the friction force when the limit block 7 moves, and the water pump 402 is started by the external control switch. The water pump 402 can pump the water source in the water tank 401 into the bellows 404 through the water outlet 403, and then the water source is transported to the connecting pipe 405 through the bellows 404. , water is sprayed out from the nozzle 407 through the branch pipe 406, and used together with the brush 305, the glue remaining on the screen drum 5 and the inner wall of the screen can be cleaned to prevent the residual glue from affecting the screening effect. At the same time, the bellows 404 has a telescopic performance. When the screen drum 5 vibrates, the bellows 404 can be telescopic according to the amplitude and direction of the vibration, so as to absorb and disperse the force generated by the vibration. This elasticity ensures that the connection between the bellows 404 and the water outlet 403 and the connecting pipe 405 is always kept tight, effectively preventing the occurrence of falling off or loosening.

[0038] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
