Description

Technical field [0001] The invention relates to a temperature control device, in particular to a temperature control system for a high-efficiency and energy-saving cone twin extruder. Background technique [0002] The extrusion molding temperature is a necessary condition to promote the plasticization of the molding material and the flow of the plastic melt. It has a very important impact on the plasticization of the material and the quality and output of the product during the extrusion molding process. In the extrusion molding process, after the material enters the extruder from the granular solid state, it must be conveyed, compacted, melted, and homogenized until the high-temperature molten parison is extruded from the die. The temperature change is very complicated. Solving the extruder molding temperature control problem will directly affect whether the extruder molding process can proceed smoothly, the quality of the pipe and the level of output. The current extruder temp...
