Description

Plastic particle screening device capable of avoiding screen hole blockage based on gravity change

Technical Field

The invention relates to the technical field of plastic processing, in particular to a plastic particle screening device capable of avoiding screen hole blockage based on gravity change.

Background

The plastic granulation is a process of plastic machining, raw materials adopted during plastic granulation need to be pretreated, raw materials with proper sizes are left, large-particle raw materials are removed, and the influence on the quality of subsequent granulation is avoided, so that a raw material screening device for plastic granulation production needs to be used.

Easily degradable's plastic granules need select separately through sorting unit when using to select temporarily can not or the large granule plastic granules of inconvenient use, so that can do benefit to and produce the processing at the plastic granules of certain size, among the prior art, because sorting unit's structure sets up unreasonablely, when using, has following problem: 1. most screening equipment adopts one-time screening, so that material waste caused by the coarse screening cannot be avoided, and economic loss is caused. 2. The plastic particles can not be uniformly dispersed for screening, and the material body is blocked at the feed inlet because of manual one-time large-amount dumping, or the plastic particles are accumulated together when on the sieve plate, so that the using effect of uniform screening can not be achieved. 3. Because plastic granules's plasticity can't avoid plastic granules can the joint in the sieve mesh when the screening, brings the difficulty for subsequent screening.

Therefore, aiming at the problems, the plastic particle screening device capable of avoiding the screen holes from being blocked based on the gravity change is provided, the problems can be greatly avoided, and the waste of material bodies caused by one-time screening is avoided by adopting coarse screening and fine screening; the problem that plastic granules are easy to block the feed inlet is also solved, and the problem that the plastic granules are clamped in the sieve pores is avoided through the change of gravity.
