[0030] Specifically, during operation / use of this lithium battery electrode material screening and recycling device: At the start of operation, lithium battery electrode materials are fed into the inlet of screening component 2. Screening component 2 is fixed to the top of frame 1, and its screen plate is designed to separate materials of different particle sizes. Drive component 3 immediately starts: transmission motor 9 drives pulley 10 to rotate via motor shaft. Pulley 10 transmits power to the transmission end of screening component 2 via belt drive, causing the entire screening component 2 to move. Simultaneously, transmission structure 5 begins to function. The transmission end of screening component 2 passes through transmission box 8 and drives rotating wheel 11 to rotate. Push rod 14 on the surface of rotating wheel 11 slides within sleeve plate 13 fixed to extension rod 12, generating regular reciprocating motion. The sliding of push rod 14 within sleeve plate 13 is constrained by limiting plate 7 and guide rod 6, generating regular oscillations. This oscillation force acts on the screen plate, and the material vibrates and produces… The "fluidization" effect allows fine particles to pass smoothly through the screen holes due to low friction. During the vibration, the supports 17 on both sides of the screening component 2 and the frame 1 are movably connected to the crank 18 through the pin shaft. The crank 18 drives the connecting plate 15 to move laterally back and forth as the screening component 2 vibrates. When the connecting plate 15 moves laterally, the movable block 23 moves with the connecting frame 19, driving the helical gear 24 on it to rotate. The helical gear 24 meshes with the helical gear 24 at the top of the reciprocating screw 20, and the ratchet 25 assembly interacts with the pawl, so that the ratchet 25 drives the helical gear 24 only when the connecting plate 15 moves in one direction, thereby forcing the reciprocating screw 20 to rotate. This rotation causes the screw sleeve 21 to move along the thread of the reciprocating screw 20, thereby adjusting the position of the striking block 16. Under the action of elasticity, the striking block 16 periodically hits the discharge end of the screening component 2 to remove any residual clogging material and ensure smooth discharge.
