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 pellets refer to the raw material particles used in the plastic processing process, usually the raw materials of thermoplastic plastics or thermosetting plastics. These plastic pellets are usually processed into various plastic products through injection molding, extrusion, blow molding and other processes.

[0003] Plastic pellets can be of different types, including polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), polyamide (PA), polycarbonate (PC), etc. Each plastic pellet has different physical and chemical properties due to its different chemical composition.

[0004] Plastic pellets are usually in the form of small spheres or ovals to facilitate even distribution and flow in processing equipment, but there are also other shapes of plastic pellets, such as flakes or squares.

[0005] The specifications of plastic pellets can vary according to their use and processing requirements, including color, size, melt index, etc.

[0006] Plastic pellets need to be dried according to specific process requirements before processing to remove moisture from them in order to avoid bubbles during processing or affect other properties of the product.

[0007] At present, after the granulation or pelletizing of plastic pellets is completed, they need to be screened to recycle the plastic pellets that are below or above the product size. Most of the methods are to manually pour the plastic pellets onto the screen, screen them, and then discharge them. It is impossible to achieve flow work, resulting in a greatly reduced efficiency in sorting plastic pellets. Utility Model Content
