Plastic granulation post-treatment process

Abstract

The invention relates to a plastic granulation post-treatment process which comprises a bottom plate, an air jetting rack, a flotation device and a feeding inlet. The air jetting rack is mounted at the upper end of the bottom plate. The flotation device is mounted at the upper end of the air jetting rack. The feeding inlet is mounted at the lower end of the left side of the flotation device and communicates with the flotation device. The plastic granulation post-treatment process can solve the existing problems that when granules are subjected to post-treatment, the dehumidification drying effect of the granules is poor, the granules are prone to have bubbles and cracks, and newly extruded plastic is liable to be bonded together, so that the granules have poor using effect and are unfavorable for subsequent processing use; and meanwhile, when the granulated granules are screened, the screening effect is poor, the sorting precision is low, and the granules can not be collected quickly after being sorted. The process has the advantages of good drying dehumidification effect, high precision of sorting, high efficiency and the like.

Description

technical field [0001] The invention relates to the field of plastic granulation processing, in particular to a plastic granulation post-treatment process. Background technique [0002] The granulation process is a production process in which polymer resin and various additives and additives are measured, rolled, plasticized, and pelletized to make granulated plastics. Plastic granules are semi-finished products in the plastic molding processing industry. , injection molding, hollow blow molding, foaming and other molding processing and production of raw materials. [0003] At present, when the existing plastic granulated pellets are post-treated, there are usually the following defects: 1. The dehumidification and drying effect of the pellets is poor, and the pellets are prone to bubbles and cracks, and the freshly extruded plastic is easy to bond Together, the use effect of the pellets is poor, which is beneficial to subsequent processing and use; 2. When sieving the gran...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the dehumidification and drying effect of the existing pellets is poor, the pellets are prone to air bubbles and cracks, and the freshly extruded plastics are easily bonded together, resulting in poor use effect of the pellets. It is beneficial for subsequent processing and use. At the same time, when screening the granulated granular materials, the screening effect is poor, the sorting accuracy is low, and the granular materials cannot be collected quickly after sorting.
