Feeding device for plastic injection molding by utilizing cyclone feeding

Abstract

The invention relates to the technical field of plastic injection molding, and discloses a feeding device for plastic injection molding by utilizing cyclone feeding. The feeding device comprises a cyclone feeding pipe and a feeding hopper, cyclone blades are fixedly connected to the central position in the cyclone feeding pipe, an impurity discharging pipe is fixedly connected to the outer side wall of the cyclone feeding pipe, the other end of the cyclone feeding pipe is fixedly connected with a discharging pipe, and one end of the cyclone feeding pipe is fixedly connected with a feeding pipe; and raw materials enter the feeding hopper from the discharging pipe to complete the conveying, meanwhile, centrifugal force generated by heavy impurities is large, the heavy impurities horizontallyenter the impurity discharging pipe along the outer sides of the cyclone blades to complete separation of the impurities, meanwhile, scattering blades are further arranged in the feeding pipe and driven by airflow to rotate, and when the raw materials enter the feeding pipe, the raw materials are scattered, so that the raw material particles adhered together are scattered, and the treatment effect of the device on the raw materials is further improved.

Description

technical field [0001] The invention relates to the technical field of plastic injection molding, in particular to a feeding device for plastic injection molding using cyclone feeding. Background technique [0002] Injection molding is a method of producing shapes for industrial products. Products usually use rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding molding method and die-casting method. Injection molding machine is also known as injection molding machine or injection. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. At present, when plastic parts are injected, it is usually necessary to pretreat the raw materials to improve the purity of the raw materials. Injection quality. [0003] In the prior art, the feeding device usually needs to go through multiple processes such as dispersing, breakin...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a feeding device for plastic injection molding using cyclone feeding, which has the principle of using cyclone separation, so that the raw materials can be dispersed, broken up, dehumidified and removed only through one process. At the same time, it can automatically adjust the conveying speed according to the amount of raw materials, which solves the problem that the feeding device usually needs to go through multiple processes such as dispersing, breaking up, dehumidifying and removing impurities. It occupies a large area and is The production cost is high, and at the same time, during the feeding process, there will be blockage of raw materials. In addition, it is not possible to intelligently adjust the amount of raw materials according to the amount of raw materials, and the degree of intelligence is low.
