[0039] In some examples, in order to achieve the effect of screening the materials, the screening assembly 5 is designed, the ring-shaped frame 5-1 is arranged between the outer frames 3, a plurality of springs 5-2 are arranged around the inner side of the ring-shaped frame 5-1, the sieve disc 5-3 is connected between the springs 5-2, the sieve disc 5-3 is used for screening the crushed plastics, the arc-shaped groove 5-4 is formed around the outer surface of the sieve disc 5-3, the control motor 5-5 and the driving gear 5-6 are fixedly connected to the ring-shaped frame 5-1, the sliding groove 5-7 is further formed around the outer surface of the ring-shaped frame 5-1 and the rotating frame 5-8 is slidably connected in the sliding groove 5-7, the external gear 5-9 is arranged around the outer surface of the rotating frame 5-8 and engaged with the driving gear 5-6, the rotating frame 5-8 can be rotated by the driving motor 4, the pushing rod 5-10 is arranged on the inner side of the rotating frame 5-8, one end of the pushing rod 5-10 abuts against the arc-shaped groove 5-4, when the rotating frame 5-8 rotates, the sieve disc 5-3 can be pushed by the pushing rod 5-10, the sieve disc 5-3 shakes in the ring-shaped frame 5-1, and the screening effect is achieved.

[0040] As shown in Figures 1-4 The electrostatic separation assembly 6 comprises a rotating shaft 6-1 rotatably connected in the base frame 1, the rotating shaft 6-1 is connected to the output end of the driving motor 4, a plurality of electrostatic discs 6-2 are arranged on the rotating shaft 6-1, an electrostatic generator 6-3 is arranged on the side surface of the base frame 1, a tray 6-4 is fixedly connected between the base frames 1, the tray 6-4 is sleeved outside the electrostatic disc 6-2, a plurality of scraping strips 6-5 are arranged on the surface of the electrostatic disc 6-2, the scraping strips 6-5 are fitted with the surface of the electrostatic disc 6-2, a sliding material frame 6-6 is arranged on the base frame 1, the sliding material frame 6-6 is connected with the tray 6-4, a second motor 6-7 is arranged at one end of the sliding material frame 6-6, and a spiral auger 6-8 is arranged at the output end of the second motor 6-7.

[0041] In some examples, to achieve the effect of electrostatically cleaning metal particles from plastic, an electrostatic separation component 6 is designed. A rotating shaft 6-1 is rotatably connected inside the base frame 1 and its rotation is controlled by a drive motor 4. An electrostatic disk 6-2 is installed on the rotating shaft 6-1. An electrostatic generator 6-3 is installed on the side surface of the base frame 1, which can generate static electricity to attract metal from the electrostatic disk 6-2. A tray 6-4 is fixed inside the frame and multiple scrapers 6-5 are installed on the inner side. When the electrostatic disk 6-2 rotates, the scrapers 6-5 can scrape the metal parts attracted on the surface into the tray 6-4. One end of the tray 6-4 is connected to a sliding frame 6-6, and the collected metal particles will slide into the sliding frame 6-6. A second motor 6-7 and a spiral auger 6-8 are installed in the sliding frame 6-6 to transport the metal particles outward.

[0042] For example, such as Figure 1 As shown, the diameter of the sieve plate 5-3 is smaller than the inner diameter of the ring frame 5-1.

[0043] In some examples, a smaller sieve 5-3 is used, which allows the sieve 5-3 to wobble off-axis.

[0044] For example, such as Figure 3 As shown, the pallet 6-4 is fixed at an inclined angle, and the lowest part of the pallet 6-4 is connected to the slide rack 6-6.

[0045] In some examples, by tilting the angle, all the collected metal particles can be rolled into the slide rack 6-6.

[0046] For example, such as Figure 4 As shown, the inner wall of the arc-shaped groove 5-4 and one end of the push rod 5-10 are both spherical structural surfaces.

[0047] In some examples, the spherical structural surface improves the sliding effect between the push rod 5-10 and the arc groove 5-4.

[0048] When processing is required, the crushed plastic falls into the sieve tray 5-3. The control motor 5-5 is started, which drives the external gear 5-9 through the drive gear 5-6, causing the push rod 5-10 to push the sieve plate to shake repeatedly. During the shaking process, the sieving of the plastic is accelerated. The falling plastic enters the conveyor belt 2 and is conveyed forward. The rotating shaft 6-1 is started to control the electrostatic disk 6-2 to start rotating. At the same time, the electrostatic generator 6-3 is turned on to generate static electricity in the electrostatic disk 6-2. As the electrostatic disk 6-2 rotates in the plastic, it can attract the metal particles in the plastic. The attracted metal particles are scraped off by the scraper 6-5 into the tray 6-4, and then rolled into the sliding frame 6-6 at an inclined angle. Finally, the metal particles are output outward by the spiral auger 6-8.

[0049] It should be noted that the above examples are only used to illustrate the technical solutions of the present disclosure rather than limit the present disclosure. Although the present disclosure is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and all should be covered in the scope of the claims of the present disclosure.
