Through the reasonable simplification of the pin barrel extruder structure , we get the model for numerical simulation and experiment. 本文通过对销钉机筒挤出机结构的合理简化，得到数值的和实验的分析模型。
The device comprises a mixing plastifying screw, a machine barrel, a screw driving system, a bracing frame and a bearing arranged on the bracing frame. 该装置包括混炼塑化的螺杆和机筒，螺杆驱动系统，支撑架以及装在支撑架上的轴承。
