A connecting frame 412 is fixedly connected to the upper surface of the support plate 411. A rotating hole 413 is formed on the surface of the connecting frame 412. A servo motor 414 is fixedly connected to the side surface of the connecting frame 412. The connecting frame 412 is located on the inner wall of the rotating hole 413 and is rotatably connected to a bidirectional shaft 415. The bidirectional shaft 415 is bolted to the driving end of the servo motor 414.

[0025] The auxiliary component 4 also includes a guide unit 42, which includes a T-shaped frame 421. The T-shaped frame 421 is threadedly connected to the surface of the bidirectional shaft 415. The lower surface of the T-shaped frame 421 is fixedly connected to an assembly plate 422. A limit cavity 423 is provided on the surface of the assembly plate 422. A retaining ring 424 is installed on the inner wall of the assembly plate 422 located in the limit cavity 423. A rotating shaft 425 is bolted to the inner wall of the retaining ring 424. A guide sleeve 426 is provided on the surface of the rotating shaft 425. A connecting bearing 427 is installed on the inner wall of the guide sleeve 426. The connecting bearing 427 and the guide sleeve 426 have an interference fit in the arc surface.

[0026] Specifically, there are two support plates 411 , which are symmetrical about the frame 1 . The support plates 411 can support the position of the connecting frame 412 , thereby ensuring that the connecting frame 412 is directly above the conveyor belt 2 .

[0027] Specifically, the T-shaped frame 421 is slidably connected to the inner wall of the connecting frame 412 . There are two T-shaped frames 421 , and the two T-shaped frames 421 are symmetrically arranged about the bidirectional axis 415 .

[0028] In this embodiment, the T-shaped frame 421 cooperates with the bidirectional shaft 415 to drive the servo motor 414 to move the assembly plates 422 on both sides.

[0029] Specifically, there are multiple snap rings 424, which are horizontally distributed about the assembly plate 422. The snap rings 424 can limit the position of the rotating shaft 425 within the limiting cavity 423, thereby ensuring the stability of the rotating shaft 425 in a moving state.

[0030] In this embodiment, there are three rotating shafts 425 , which are horizontally distributed with respect to the assembly plate 422 , and the rotating shafts 425 pass through the lower surface of the assembly plate 422 .
