Plastic particle screening device

Abstract

The invention discloses a plastic particle screening device. The plastic particle screening device comprises a first screening box and a second screening box which are arranged obliquely, and the discharging end of the first screening box directly faces the upper part of the feeding end of the second screening box in a vertical direction. The discharging ends of the first screening box and the second screening box are open, and a base is further included, wherein the first screening box and the second screening box are fixedly mounted above the base by brackets, a first screen is disposed on the bottom surface of the first screening box, a second screen is disposed on the bottom surface of the second screening box, the screen diameter of the first screen is smaller than the screen diameterof the second screen, a first storage mechanism disposed at the lower end of the first screening box, a second storage mechanism disposed at the lower end of the second screening box, and a third storage box disposed under the discharging end of the second screening box. Material-pulling screening mechanisms are arranged in the first screening box and the second screening box.

Description

technical field [0001] The invention relates to the technical field of plastic production and processing, in particular to a plastic particle screening device. Background technique [0002] Plastic particles, commonly known as plastic particles, are raw materials for storage, transportation and processing of plastics in the form of semi-finished products. [0003] The granulation process of the plastic granulator generally includes: extruder feeding, screw extruder extrusion, cold water tank cooling and drawing, granulator granulation, and finished product collection. When the granulator cuts the columnar plastic particles, the length of the columnar particles is mainly determined by the rotating speed of the pelletizing knife and the wire drawing cooling condition, but the water temperature in the cold water tank often fluctuates with the production, so the wire drawing cooling condition is unstable. This in turn will affect the length of the columnar particles. In the ac...
