When the pellet machine is working, its temperature must be controlled well. Once the temperature changes, its working product will also change. The main temperature control of the host is mainly based on the plastic extrusion of wire and cable insulation and sheath, which is carried out according to the deformation characteristics of thermoplastic to make it in a viscous state.
In addition to requiring external heating of the screw and barrel to melt and extrude the plastic, it is also necessary to consider the heat generated by the screw of the plastic granulator when extruding the plastic. Therefore, the temperature of the main body of the plastic granulator should be considered as a whole, taking into account both the heating on and off of the heater and the factor of heat overflow from the screw extrusion for cooling, and having effective cooling facilities. And it is required to correctly and reasonably determine the position and installation method of the thermocouple for measuring plastic granulator components, which can accurately reflect the actual temperature of each section of the host from the readings of the temperature control instrument.
And require the accuracy of temperature control instruments to be well coordinated with the system, so that the fluctuation stability of the entire host temperature control system meets the requirements of various plastic extrusion temperatures.
