[0023] In this embodiment: the polyester chips to be screened are put into the screening drum 2, and the motor 202 drives the screening drum 2 to rotate, so that the powder in the screening drum 2 and the qualified polyester chips fall through the mesh on the screening drum 2 to the screening frame 401 in the second screening box 4, and the dispersion rod 203 can assist the polyester chips to disperse while the screening drum 2 rotates, so that the polyester chips can achieve the effect of rapid screening;

[0024] Secondly, the polyester chips after the first screening are driven by the vibration motor 403 to vibrate the screening frame 401 left and right for screening. The elastic component 402 can assist the screening frame 401 in screening. At the same time, the cylinder 501 pushes the shifting frame 502 to move down into the screening frame 401. As the screening frame 401 moves left and right for screening, the powder in the polyester chips is caused to fall, while the qualified polyester chips remain in the screening frame 401. As the screening frame 401 moves left and right, the shifting frame 502 can stir the polyester chips in the screening frame 401 back and forth, thereby improving the screening efficiency.

[0025] As a technical optimization solution of the utility model, installation grooves 102 are provided on both the left and right sides of the inner wall of the first screening box 1 , and a receiving frame 3 matching the installation grooves 102 is installed inside the first screening box 1 .

[0026] In this embodiment: The receiving frame 3 is placed in the installation groove 102, and the abnormal slices staying in the screening cylinder 2 during screening can be received through the receiving frame 3.

[0027] As a technical optimization scheme of the present utility model, a storage box 504 is communicated with the rear end face of the second screening box 4, and electric guide rails 503 fixedly connected to the moving plate 5 through electric sliding sleeves are installed on both the left and right sides of the inner wall of the second screening box 4, and both electric guide rails 503 extend into the interior of the storage box 504.

[0028] In this embodiment: The electric sliding sleeve drives the moving plate 5 and the dialing frame 502 to slide into the storage box 504 for storage through the electric guide rail 503.

[0029] As a technical optimization scheme of the present utility model, the mesh diameter of the screening cylinder 2 is larger than the mesh diameter of the screening frame 401.

[0030] In this embodiment: By the mesh diameter of the screening cylinder 2 being larger than the mesh diameter of the screening frame 401, the powder and abnormal slices in the polyester slices can be screened.

[0037] Working principle: First, connect the device to an external power supply. Put the polyester chips to be screened into the screening cylinder 2 through the feed hopper 101 and the feed inlet 201, and then seal the feed inlet 201 with the sealing cover. At the same time, remove the receiving frame 3. Then, make the motor 202 drive the screening cylinder 2 to rotate, so that the powder and qualified polyester chips in the screening cylinder 2 fall through the mesh holes on the screening cylinder 2 onto the screening frame 401 in the second screening box 4. At this time, the moving plate 5 and the dialing frame 502 are located in the storage box 504. At the same time, when the screening cylinder 2 rotates, the dispersion rod 203 can assist in dispersing the polyester chips, achieving the effect of rapid screening of the polyester chips;

[0038] Secondly, the polyester chips after the first screening are vibrated and screened left and right by the vibration motor 403 driving the screening frame 401.

At the same time, the electric guide rail 503 works to drive the moving plate 5 and the dialing frame 502 to move into the second screening box 4 and be directly above the screening frame 401. Immediately afterwards, the air cylinder 501 pushes the dialing frame 502 to move down into the screening frame 401. With the left and right movement and screening of the screening frame 401, the powder in the polyester chips falls into the powder box 6 for collection, while the qualified polyester chips stay in the screening frame 401. And with the left and right movement of the screening frame 401, the dialing frame 502 can stir the polyester chips in the screening frame 401 back and forth, thereby improving the screening efficiency;

[0039] Finally, open the box door, install the receiving frame 3 in the installation groove 102, make the screening cylinder 2 rotate until the feed inlet 201 on its outer wall rotates to the lower side, and then the sealing cover can be opened to make the abnormal chips remaining in the screening cylinder 2 fall onto the receiving frame 3 for collection.
