Embodiment 1

[0020] In the embodiment, the automatic sorting equipment for waste mixed plastic particles includes an automatic control system. The automatic control system includes a host computer and a PLC controller for controlling the distance between plastic particles, the speed of the conveyor belt, the size of the air flow, and the switch of the equipment. Automatic control, electromagnetic vibration feeding system, conveyor belt, color sensor array, pneumatic nozzle, pure material collection bin, automatic push rod and waste collector; electromagnetic vibration feeding realizes automatic sorting of waste plastic particles, Avoid the disadvantages of poor sorting effect caused by feed blockage or superimposition.

[0021] The conveyor belt is an island-type conveyor belt; the color sensor array includes 7 color sensors, which are set on the outside of the island-type conveyor belt, which are red sensors, yellow sensors, blue sensors, green sensors, and purple sensors. , a black senso...

Abstract

The invention discloses automatic separation equipment of waste mixed plastics and a method thereof. The equipment comprises an automatic control system, an electromagnetic vibration feeding system, a conveying belt, a color inductor array, a pneumatic nozzle, a pure material collecting bin, an automatic push rod and a waste collector. The method comprises the following steps: (1) crushed and deironed piece-shaped or particle-shaped plastic products are fed onto the conveying belt by the electromagnetic vibration feeding system; (2) mixed plastic particles supported by the conveying belt are screened with colors through different color inductors in the color inductor array and the pneumatic nozzle in sequence, and are collected by the pure material collecting bin; and (3) wastes not identified by the color inductor array on the conveying belt are pushed into the waste collector by the automatic push rod after passing through the final color inductor. The method adopts a high-tech method to replace manual sorting, so that the production labor force is reduced; and compared with manual sorting, the method is faster in speed, is stronger in continuity, and greatly improves the production efficiency.

Description

technical field [0001] The invention relates to the technical field of color sorting of recycled mixed plastics, in particular to an automatic sorting device and method for waste mixed plastics. technical background [0002] Since entering the 21st century, the application of plastic products has spread across various fields such as home appliances, automobiles, mechanical equipment, and decoration materials. When various products are scrapped and eliminated, a large amount of waste plastics are produced. The three main methods of dealing with the waste plastic waste generated every day in the world are landfill, incineration and recycling. Because the natural degradation time of ordinary plastic waste is very long, it usually takes a hundred years to degrade, and a large amount of methane and other harmful substances will be produced during the degradation process. The landfill method not only causes waste of resources, but also brings potential environmental hazards; and ...
