Diseño e implementación del nuevo sistema de control para la maquina extrusora Haake Rheomex CTW100P del Centro de Investigaciones Aplicadas a Polímeros de la Escuela Politécnica Nacional

Abstract

This project presents the design and implementation of the new control system for the Haake Rheomex CTW100P extruder machine from the Center for Applied Polymer Research of the National Polytechnic School. A sensor stage, a power stage and a control stage were implemented. The conditioning circuits were designed for each of the temperature, pressure and torque sensors that the extruder machine has. To vary the speed of the rheometer motor, a speed sensor was coupled to the motor shaft and a switch was adapted in the rheometer remote control. The program for the reduced plate processor and the program for the reduced plate computer was developed. A main interface was developed on the 52Pi screen and a secondary interface on the Nextion screen for the display of the temperature, pressure, torque, engine speed values and setting of the temperature and engine speed values.
