When the transmission column 422 rotates, it drives the cam 4331 to rotate synchronously. The cam 4331 pushes the control plate 431 to move upward in the vertical direction. After the control plate 431 moves to the highest point, the extrusion spring 4332 pushes the control plate 431 to move downward in the vertical direction. In this way, the control plate 431 can be driven to move back and forth continuously in the vertical direction. The control plate 431 drives the pore brush 4311 to move synchronously. The pore brush 4311 is inserted upward into the mesh on the surface of the screen plate 3, which can effectively prevent the mesh on the surface of the screen plate 3 from being blocked.
