Why does the extruder barrel screw produce noise?Why does the extruder barrel screw produce noise?
In the process of extrusion processing, the screw of the extruder will make a noise when it rubs against the inner wall of the barrel.The reasons for this friction phenomenon are:
1. The assembly gap between the barrel screw of the rubber extruder and the supporting transmission shaft is too large, and the center lines of the two shafts are not concentric during rotation, and the error is too large.
II. Rubber extruder barrel screw bending deformation, the straightness of the shaft centerline is very large.
III. The perpendicularity between the end surface of the barrel screw of the rubber extruder and the flange of the machine base and the center line of the barrel cannot be guaranteed, and the error is large.
IV. Rubber extruder barrel screw is assembled in the extruder barrel, the error of concentricity of the two parts is large.
