Preheating treatment process before plastic particle injection molding

Abstract

The invention relates to a preheating treatment process before plastic particle injection molding. A bottom plate, a supporting frame, a feeding device and a preheating device are included, the supporting frame is mounted on the upper end of the bottom plate, the section of the supporting frame is of a right trapezoid structure, the feeding device is mounted on the upper end of the left side of the supporting frame, the preheating device is mounted in the supporting frame, and the problems that when an existing device carries out preheating on plastic particles, the plastic particles are commonly stacked together, the preheating effect in the plastic particles is poor, heating is not uniform, subsequent machining of the plastic particles is affected, when the existing device carries out preheating on the plastic particles, the heated plastic particles are easily bonded on the outer side of the conveying belt, the bonded impurities on the conveying belt cannot be effectively removed, and the machining efficiency of the plastic particles is affected can be solved.

Description

technical field [0001] The invention relates to the technical field of plastic particle processing, in particular to a preheating process for plastic particles before injection molding. Background technique [0002] Plastic is a polymer compound made of monomer as raw material through addition polymerization or polycondensation reaction. It is composed of synthetic resin and fillers, plasticizers, lubricants, colorants and other additives; plastic particles can be further processed into various Plastic products and plastic granules are usually prepared by mixing plastic raw materials and various masterbatches, melting them, and then extruding them through an extruder. [0003] At present, the existing plastic granules usually have the following defects when they are preheated: 1. When the existing equipment preheats the plastic granules, the plastic granules are usually piled up together, making the internal preheating effect of the plastic granules poor 1. Uneven heating a...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that when the existing equipment preheats the plastic granules, the plastic granules are usually piled up together, so that the internal preheating effect of the plastic granules is poor and the heating is uneven, which affects the subsequent processing of the plastic granules. When preheating plastic granules, the heated plastic granules tend to adhere to the outside of the conveyor belt, which cannot effectively remove the impurities adhering to the conveyor belt, affecting the processing efficiency of plastic granules, etc.
