Description

Technical Field

[0001] The utility model relates to the technical field of plastic pellet sorting, in particular to a plastic pellet sorting device. Background Art

[0002] Plastic particles, also known as plastic granules, refer to granular plastics. Common plastic particles include general-purpose plastics, engineering plastics and special plastics. General-purpose plastics include polypropylene, polyethylene, polyvinyl chloride, polystyrene, polyester and polyurethane. Engineering plastics include nylon, polytetrafluoroethylene, polyoxymethylene and polycarbonate silicone. In the production and processing of plastic particle processing equipment, it is necessary to screen and sort the plastic particles in some processes so that plastic particles of different sizes can be distinguished.

[0003] For example, the prior art Chinese patent publication number "CN215030984U" provides a sorting device for processing plastic particles, including a sorting box body, a feeding box hopper is fixedly installed on the top of the sorting box body, and a first sorting plate rack, a second sorting plate rack and a discharge inclined plate are fixedly installed inside the sorting box body, the second sorting plate rack is located at the bottom of the first sorting plate rack and at the top of the discharge inclined plate, and the first sorting plate rack has a first sorting sieve hole running through the plate surface.

[0004] The device enables plastic particles of different sizes to slide out from the first sorting plate rack, the second sorting plate rack and the bottom of the discharging inclined plate respectively, and are output through the first discharging compartment rack or the second discharging compartment rack. By setting a buffer bar, the plastic particles can be blocked and slowed down when sliding, so that the sorting and screening are more complete, achieving the effect of efficient multi-stage screening and sorting, facilitating the rapid circulation and output of plastic particle materials while sorting, and improving the overall sorting and screening efficiency.

[0005] In the existing plastic pellet sorting device, the plastic pellets are only sorted by rolling in the sorting device, and cannot be mixed and turned. In addition, the plastic pellets are clumped and cannot be mixed and dispersed, which affects the sorting of the plastic pellets. Moreover, when it is necessary to sort out plastic pellets of different diameters, the diameter of the drop hole after screening and sorting cannot be quickly adjusted, which makes it inconvenient to sort out plastic pellets of different diameters.
