Quantitative conveying dehumidification device for plastic particles

Abstract

The invention discloses a quantitative conveying dehumidification device for plastic particles. The quantitative conveying dehumidification device for the plastic particles comprises a controller, a shell body, a rotary barrel, a material bucket, a tray, a bellows and a hopper, wherein the rotary barrel is concentrically arranged in the shell body; the tray is arranged below the rotary barrel; three partitions are annularly arrayed in the rotary barrel to divide the inner cavity of the rotary barrel into three independent cavity bodies; the material bucket is located above one independent cavity body; an electronically-controlled valve linearly connected with the controller is arranged at the bottom of the material bucket; an unloading port and an air pore area which are located below theother two independent cavity bodies are formed in the tray; and micropores are closely distributed in the air pore area. Through the manner, according to the quantitative conveying dehumidification device for the plastic particles, the rotary barrel comprising the three independent cavity bodies is specially designed and cooperated with the tray, and take charge of charge, ventilation and dehumidification, and discharge separately; and the quantitative conveying dehumidification device for the plastic particles is simple in structure, and realizes dehumidification in a quantitative conveying process for the plastic particles.

Description

technical field [0001] The invention relates to the field of machinery related to plastic production, in particular to a plastic particle quantitative delivery dehumidification device. Background technique [0002] Plastic particles are raw materials for the production of various plastic products, which are convenient for mixing and feeding additives. For example, an injection molding machine heats plastic particles to form a molten plastic fluid, then injects the plastic fluid into a mold, and cools and solidifies it into a plastic product. [0003] Obviously, in the production process, the injection molding machine needs to be heated at high temperature to melt the plastic particles. If the humidity of the plastic particles is high, steam will be formed when heated, which will affect the normal injection injection and cause product defects. Therefore, plastic particles need to be melted. Dehumidification. Most of the existing dehumidification equipment has complex struct...

Problems solved by technology

[0003] Obviously, in the production process, the injection molding machine needs to be heated at high temperature to melt the plastic particles. If the humidity of the plastic particles is high, steam will be formed when heated, which will affect the normal injection injection and cause product defects. Therefore, plastic particles need to be melted. dehumidification

Most of the existing dehumidification equipment is complex in structure, high in cost, and cannot carry out quantitative feeding of plastic particles, which is difficult to meet the needs of automatic production of injection molding machines
