A screening device for separating plastic particles

Abstract

The invention discloses a screening device used for separating plastic particles. The device comprises a shell, a feeding opening is formed in the top of the shell, a sheltering mechanism is arrangedabove the feeding opening, fixing mechanisms are symmetrically arranged in the shell, first screen plates are arranged in the fixing mechanisms, second screen plates are arranged below the first screen plates, spring mechanisms are arranged on one sides of the second screen plates, the other sides of the second screen plates are fixedly connected with a first sleeve, a second discharging opening is formed in the side, away from the first discharging opening, of the shell, cooling mechanisms are arranged below the spring mechanisms, a third discharging opening is formed in the bottom of the shell, a switch mechanism and a limiting mechanism are arranged above the third discharging opening, multiple supporting legs are fixedly arranged below the shell, and a damping mechanism is arranged onthe outer surfaces of the supporting legs. The screening device has the beneficial effects that through two layers of screen plates, screening is carried out, the screened particles are not large in size difference, and the subsequent production steps are facilitated.

Description

technical field [0001] The invention relates to the field of plastic production, in particular to a screening device for separating plastic particles. Background technique [0002] In the process of plastic production, screening equipment is often required for screening, because machine errors may cause large particle volume differences, affecting subsequent production links. The screening device can quickly screen out particles with large volume differences to improve production efficiency. However, some screening devices currently have only one screening step, which cannot screen larger particles in a more specific manner, and there are still large volume differences in the screened plastic particles. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at the problems in the related art, the present invention proposes a screening device for separating plastic particles, so as...
