Experimental Study of Yin and Yang Rotor Type Twin Screw Structure
In order to design a more efficient twin screw to improve the working efficiency of extruder;A twin screw model with Yin and Yang rotors was proposed.Based on the spiral screw model,a twin screw with Yin and Yang rotors was designed.The simula-tion was compared with the traditional twin screw and the accuracy of the new twin screw was verified by experiments.SolidWorks software was used to build the model,and ANSYS was used to simulate the flow channel value.The working state of the material in the barrel was obtained.The macroscopic pressure velocity vector and velocity streamline of the Yin and Yang rotor-type twin-screw were analyzed;The results show that the macro-pressure of the yin-yang rotor-type twin screw is in an increasing state,the velocity vector distribution is not uniform,and the velocity flow line is chaotic.The yin-yang rotor-type twin screw can effectively increase the material transmission speed in the barrel,change the material transport state,and improve the material extrusion volume The research results enrich the research ideas of twin-screw and provide a theoretical basis for the design and application of high-efficiency extruder.
