Abstract

The invention relates to the field of plastic product equipment and particularly relates to a plastic particle vibratory screening device which comprises a feed hopper, a classifying screen, a support and a vibrator, wherein the classifying screen is supported on the support, the bottom of the classifying screen is step-shaped, the surface of the classifying screen is corrugated, the classifying screen is set to be provided with multiple levels of screening holes with different apertures, the apertures of the screening holes from an inlet to an outlet of the classifying screen are gradually increased, a sliding chute is arranged below each level of the screening holes, the vibrator is fixed below the classifying screen, the feed hopper is arranged at the highest point of the support and is provided with a channel communicated with the classifying screen, and a support cross frame is arranged below the feed hopper. The plastic particle vibratory screening device has the beneficial effects that since the surface of the classifying screen is corrugated, and the apertures of the screening holes are gradually increased from the inlet to the outlet, the plastic particles can be quickly classified.

Description

technical field [0001] The invention belongs to the field of plastic product equipment, in particular to a vibration screening device for plastic particles. Background technique [0002] Plastic film is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, used for packaging, and as a film layer. The raw materials for extrusion molding of plastic films are generally larger granular plastics or some plastic scraps, so these plastic particles are usually crushed to avoid unevenness or individual difficulty in melting during the hot-melt process. Generally, plastic particles need to be screened before injection molding, and a screening device will be used, but some crystal particles are of different sizes, so it is necessary to select and separate particles of different sizes; and in other industries, it is necessary to strictly ensure that the particles The size uniformity of the product must be processed with a screening device to mee...
