Problems solved by technology

[0002] In the process of cable processing, the cable wire is overmolded. The overmolding process is to extrude the plastic in the screw extruder and wrap it outside the cable core to form the cable wire. The extruder heats and melts the cable through the extrusion screw. For plastic extrusion, the extruder screw needs to be replaced frequently due to the difference in the diameter of the cable. To ensure the stable rotation of the screw, the screw and the rotating device are usually tightly matched. The existing screw replacement is to use external force to beat one end of the screw The screw is forcibly knocked out. This replacement method is easy to deform the screw end, which will affect the installation of the next screw. Moreover, the force of manual external force is not uniform, and the removal of the screw is not easy.

Abstract

The invention provides an improved screw machine structure. According to the improved screw machine structure, a screw can be conveniently taken out, deformation of the screw end is effectively prevented, and dismounting and replacement of the screw are well realized. The improved screw machine structure comprises a screw housing, wherein an extrusion screw is arranged in the screw housing. The improved screw machine structure is characterized in that a flange cover is arranged at the driving end, which corresponds to the extrusion screw, of the screw housing; a threaded through hole is formed in the flange cover and is connected with the driving end of the extrusion screw.
