Single-chip microcomputer control system for extruder

Abstract

The invention discloses a single-chip microcomputer control system for an extruder. The system comprises a power supply module, a single-chip microcomputer module, a thermocouple temperature measurement module, a heating control module, a cooling control module, a digital signal input module, a digital signal output module, an analog signal input module, an analog signal output module, a communication module, a man-machine interface, a thermal resistance measurement module, an SD card module and a debugging port. At present, extruder control systems in the market are divided into two kinds, one kind is traditional control systems mainly composed of discrete devices, such as relays, temperature control meters, etc., and the other kind is PLC control systems. The traditional control systems require more discrete devices, and have the disadvantages of complex circuit, poor reliability, poor self-protection ability and incapability of communicating, exchanging and storing data. The PLC control systems are high in cost, and require the extruder manufacturers to further develop control programs, so that the manufacture period is long. The novel single-chip microcomputer control system provided by the invention effectively solves the above problems, and has the advantages of high integration level, high reliability, low cost, high automation degree, and complete communication functions.

Description

technical field [0001] The invention relates to an extruder control system, in particular to an extruder control system with a single-chip microcomputer as the core. Background technique [0002] With the rapid development of the plastics industry, extruders, as the core equipment for plastic processing, are increasingly used. At the same time, the processing characteristics of extruders have an important impact on the performance, production efficiency, and manufacturing costs of plastic products. [0003] Extruders include single-screw extruders, twin-screw extruders, and multi-screw extruders. [0004] As the brain of the extruder, the control system plays a vital role in improving the performance, intelligence and informatization level of the extruder itself. [0005] At present, the middle and low-end extruders on the market are controlled by scattered components such as relays and temperature controllers. There are many components, complex wiring, heavy wiring workloa...

AI Technical Summary

Problems solved by technology

The new extruder control system can effectively solve many deficiencies in the current distributed component control system with relays and temperature control meters as the core on the market, as well as the high cost of the control system represented by PLC.
