Screw extruder for chemical fiber production

The invention relates to the technical field of chemical fiber production, in particular to a screw extruder for chemical fiber production, which comprises a bottom plate, an extruder body is mounted at the top of the bottom plate, and a mixing box is mounted at the top of the extruder body. Raw materials are put into the mixing cavity, then the output end of a first servo motor drives a rotating rod to rotate, the rotating rod drives a stirring rod to rotate, the stirring rod mixes the raw materials in the mixing cavity, and meanwhile the rotating rod drives a first clutch sleeve and a spiral conveying rotating shaft to rotate through a second belt wheel; the raw materials in the mixing cavity enter the conveyor through the feeding valve and then enter the mixing cavity through the discharging valve, so that the raw materials in the mixing cavity are evenly mixed, the raw materials are evenly mixed, and the quality of chemical fibers is good. 本发明涉及化纤生产技术领域，尤其是一种化纤生产用螺杆挤出机，包括底板，所述底板的顶部安装有挤出机本体，所述挤出机本体的顶部安装有混合
