Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of plastic particle processing, especially to a plastic particle drying mechanism. BACKGROUND
[0002] Plastic particles are formed by extrusion in the production process, and then cooled by water. After cooling, the formed plastic needs to be cut into particles. Since the plastic is directly cut after cooling, water will remain on the surface of the plastic particles. The presence of water will seriously affect the quality of plastic products. For example, during injection molding, plastic particles containing water will cause defects such as bubbles, silver wires, and deformation in the product, reducing the strength and appearance quality of the product. Therefore, the surface of the plastic particles needs to be dehydrated and dried.
[0003] In the production of plastic products, the drying of plastic particles is crucial. Currently, most plastic drying devices only perform single drying when drying plastic. This may cause some plastic particles to not be completely dried when there are many plastic particles, resulting in uneven quality of the plastic particles and affecting subsequent processing.
[0004] To address the technical problem of uneven drying caused by single drying of plastic particles, the present application proposes a plastic particle drying mechanism. SUMMARY
