摘　　要：简介了双螺杆挤出机在食品、塑料捏合混炼加工领域中的应用。从啮合同向旋转双螺杆相对运动原理及其截面形状入手,利用计算机软件Pro/E进行辅助设计铁磁粉/CPE捏合混炼双螺杆挤出机,用以革新磁性塑料制备工艺。并利用中心距法对螺纹理论曲线进行修正,最后进行运动仿真模拟,确保转动无干涉。实际应用结果表明:文章介绍的双螺杆几何造型方法具有很强的适用性和可操作性。The application of twin screw extruder in the mixing of food or polymer was introduced briefly. The relativistic moving mechanism and the cross section geometry of the meshing co-rotating twin screw were introduced. By using CAD software PRO/E, the ferrite/CPE mixing twin screw extruder was designed for innovation of the plastic magnet process. And then, the screw theoretical curve by center-distance method was amended, and the simulation of screws rotation was conducted to insure noninterference. The result of the application showed that this design method for the co-rotating screw was powerful in application and operation.
