The mounting plate 2 is fixedly connected with a connecting plate 21, and the driving motor 31 is fixedly arranged on the connecting plate 21.

[0033] The limiting assembly 33 comprises a limiting spring 331 and a limiting telescopic rod 332 fixedly arranged on the mounting plate 2, the limiting spring 331 and the limiting telescopic rod 332 are fixedly connected with the pushing plate 34 at a side away from the mounting plate 2, and the limiting spring 331 is sleeved outside the limiting telescopic rod 332. The pushing plate 34 is connected with the screening mechanism 4 at a side away from the limiting assembly 33, and the pushing plate 34 abuts against the cam 32.

[0035] The mounting rack 5 comprises a supporting rod 51 and a plurality of supporting plates 52, the supporting plates 52 are fixedly connected with the supporting rod 51, a through hole 53 is formed in each of the supporting plates 52, the supporting plates 52 are in U-shaped structure, the pushing plate 34 passes through the through hole 53, and the mounting frame 411 is slidably connected with the supporting plates 52.

[0036] A plurality of first rollers 54 are arranged on the supporting plates 52, the first rollers 54 are arranged at two sides of the through hole 53, and the mounting frame 411 abuts against the first rollers 54.

[0037] Two limiting sliding grooves 413 are formed in the mounting frame 411, the limiting sliding grooves 413 are arranged at two sides of the screen 412, and the first rollers 54 are slidably connected with the limiting sliding grooves 413.

[0038] The pushing plate 34 is provided with a second roller 341 abutting against the cam 32.
