PLC-based intelligent control of recycled plastic energy-saving and environmental protection extrusion device

Abstract

An energy-saving environment-friendly extrusion device for intelligently controlling recycled plastic based on a PLC comprises an extrusion part and the PLC; the extrusion part mainly comprises an extrusion material barrel and a transmission mechanism in transmission connection with the extrusion material barrel; a heating screw is arranged in the extrusion material barrel, a heating wire is arranged in the heating screw, the extrusion material barrel is divided into seven heating segments, the seven heating segment are independent of one another, and each heating segment comprises an electromagnetic heating oil arranged on the extrusion material barrel in a sleeving manner; a cooling cavity is formed in the middle of the extrusion material barrel and is connected with a cooling system; the heating wire is connected with the PLC, and the heating temperature and the heating time of the heating wire are controlled through logic programming; PLC data are transmitted to an office computer through the internet, the data can be directly observed through the computer, and therefore production is guided, and mechanical monitoring failures are maintained; and the aim of intelligently controlling extrusion of the recycled plastic is achieved, manpower, material resources and financial resources are saved, and the device meets the sustainable development requirement.

Description

technical field

[0001] The invention relates to the technical field of plastic processing machinery, in particular to an energy-saving and environment-friendly extruding device for recycled plastics based on PLC intelligent control. Background technique

[0002] Since the formation of the modern plastics industry in 1930, after more than 80 years of rapid development, the plastics industry has become the mainstay of light industry. While the wide application of plastic products has also produced huge plastic pollution, it has caused great damage to the global ecological environment. The main treatment methods for waste plastics are landfill and incineration. However, because landfill occupies a large space, it increases the pressure on land resources. At the same time, because waste plastic is difficult to degrade, it seriously hinders water infiltration and groundwater circulation. , Secondly, the additives in waste plastics will also cause secondary pollution to the land....
