Optimization Design Of Feed Compression Section Of Single Screw Extruder Barrel Forming Method

Ordinary single-screw extruder is used to process some plastic products, itscharacteristic is as follows: simple structure, high production efficiency, continuousextrusion process, product variety, simple operation, easy to guarantee the quality ofproducts, etc; Can work most of the general plastics and engineering plastics. Forultra-high molecular weight polyethylene such materials, however, because of its largemolecular weight, heat after plasticizing performance for high elastic state, melt viscosityis high, there is no liquidity, not easy kneading, molding, so the material can not useordinary single-screw extruder molding, and barrel displayed successfully solved thisworldwide problem, and can realize ultra-high molecular weight polyethylene forefficient extrusion, but still need to continue to improve its forming theory.This article refer to the former research of normal single screw extruder theory andmethod, based on the theory of plug flow solid conveying, according to thecharacteristics of the barrel displayed, and improved. With minimum energyconsumption per unit of production for the purpose, to establish a physical andmathematical model, and using the complex method, using MATLAB software, thebarrel molding in inlet compression section of single screw extruder to optimize design,optimal geometric parameter values.
