Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic particle screening technology, specifically a plastic particle screening device. Background Technology
[0002] Plastic granules are semi-finished products used in the plastic molding and processing industry. They are also raw materials for molding and processing such as extrusion, injection molding, blow molding, and foaming. Their quality determines the quality of the finished products produced later.
[0003] As disclosed in announcement number CN221908231U, a plastic granule screening device includes a cylinder wall. A screen plate is provided on the inner wall of the cylinder wall. A main circuit is provided on the surface of the screen plate, and a branch circuit is provided on the surface of the main circuit. A connector is provided on the top of the branch circuit. A discharge port is provided on the surface of the cylinder wall. This utility model enhances the screening effect by setting the screen plate in a V-shape to increase the surface area of the screen plate. At the same time, the plastic granules will come into contact with the connector during the shaking process on the surface of the screen plate. The connector absorbs the static electricity in the plastic granules and transmits it to the grounded main circuit through the branch circuit. The main circuit transmits the static electricity to the outside, ensuring that there is no large amount of static electricity in the plastic granules that causes them to attract and clump together, thus greatly reducing their adsorption and avoiding the adsorption of impurities. At the same time, the protruding connector can break up the already clumped plastic granules that enter the cylinder wall, thereby obtaining a better screening effect.
[0004] In existing technologies, screening requires manual throwing of particles onto a screen, which results in very low screening efficiency. Therefore, a plastic particle screening device is provided. Utility Model Content
