[0024] A rack 408 is fixed to the lower end of the movable sleeve 407, a rotatable gear 409 is horizontally arranged on the support frame 1, the gear 409 is engaged with the rack 408, and one end of the gear 409 is driven to rotate by an external motor, so as to drive the gear 409 to rotate, so that the rack 408 engaged with the gear 409 can move left and right.

[0025] Sliding grooves 405 for sliding of the first mesh plate 401 are formed on the two sides of the support frame 1, and the upper end of the first mesh plate 401 is slidably connected with the lower end of the second mesh plate 402.

[0026] The device drives the external motor to rotate the gear 409, and then the gear 409 engages with the rack 408, and the rack 408 drives the movable sleeve 407 to move, so that the movable sleeve 407 drives the first mesh plate 401 to move, and the first mesh plate 401 moves to overlap the first coarse mesh holes 403 and the second coarse mesh holes 410, so that coarse polyethylene particles can be screened.

[0027] The lower end of the support leg 2 is fixed with a collection box 3, and the collection box 3 is located below the second mesh plate 402 and the first mesh plate 401, so as to facilitate collection of the screened polyethylene particles.

[0028] Meanwhile, a material guiding box 5 is fixed to the left side of the upper side of the support frame 1, and a feeding hopper 6 is fixed to the upper end of the material guiding box 5, so that the polyethylene particles can be discharged from the feeding hopper 6 and the material guiding box 5 to the first mesh plate 401 and the second mesh plate 402 arranged in an inclined manner.

[0029] In addition, the first coarse mesh hole 403 and the second coarse mesh hole 410 have the same diameter.

[0030] The working principle of the above embodiment is as follows:

[0031] In use, according to the screening use requirement of polyethylene particles of different particle sizes, if it is required to screen qualified polyethylene particles of a larger particle size, the external motor is started, the external motor drives the gear 409 to rotate, the gear 409 meshes with the rack 408, the rack 408 drives the sliding sleeve 407 to move, and thus the sliding sleeve 407 drives the first mesh plate 401 to move, the first mesh plate 401 moves to the first coarse mesh hole 403 and the second coarse mesh hole 410 overlapping, and thus coarse polyethylene particles can be screened.

[0032] Then the polyethylene particle material is discharged from the feed hopper 6 and the material guiding box 5 to the first mesh plate 401 and the second mesh plate 402 which are arranged in an inclined manner, and slides downward, so that the qualified polyethylene particles screened through the first coarse mesh hole 403 and the second coarse mesh hole 410 fall into the collecting box 3.

[0033] If it is required to use qualified polyethylene particles of a smaller particle size, the external motor is reversed, so that the gear 409 drives the rack 408 to move in the direction of the sliding sleeve 407, and then the first mesh plate 401 moves synchronously, and then the first mesh plate 401 moves to the fine mesh hole 404 being located in the second coarse mesh hole 410, so that the polyethylene particles are blocked by the first mesh plate 401 when entering the second coarse mesh hole 410, and thus can only fall from the fine mesh hole 404 for collection.
