| 中文摘要: |
| 通过分析挤出压力、挤出量和螺杆转速之间的关系说明传统橡胶冷喂料挤出机在生产中存在的问题。介绍采用挤出压力控制的新型挤出机及其不足，并在此基础上提出了挤出压力和挤出量联合控制螺杆转速的新方法。新方法的控制结合不同段螺杆的几何结构参数值和胶料粘度修正值，可综合改善挤出制品的质量与产量。 |
| 英文摘要: |
| The relationship between the extrusion pressure，extruder output and screw rotation speed was analyzed，which was used to explain the problems of traditional cold feed rubber extruder during production.The new type extruder with extrusion pressure control and its disadvantages were also introduced.Based on that，a new method of screw speed control by combined control on extrusion pressure and extruder output was proposed. The new control method took into account the geometrical structure parameters of different parts of the screw and correction to compound viscosity，and could improve the quality and output of extruded products. |
