[0002] Plastic particles are intermediate products of plastic processing, also called plastic particles, which are made of polyethylene, polypropylene and other high molecular polymers as raw materials. During production, the recycled waste plastics or new plastic raw materials are cleaned, crushed, and then heated, melted, and extruded into particles.

[0003] After the plastic particles are made, different sizes of plastic particles are formed, so a screening separation device is needed to screen the regenerated plastic particles. During screening, different size screens are installed in the device, and then the particles are screened from top to bottom, so that particles of different sizes are layered.

[0004] However, during screening, the largest particles are screened out at the top. After the first screening is completed, if the next batch of particles needs to be screened again, the larger particles are easy to block the screen holes on the screen, and the next batch of particles is easy to be above the larger particles, so it is difficult to contact the screen holes of the screen, and the screening is not down.
