Extruder Screw Arrangement Requirements and Barrel Noise Analysis

Ⅰ. The extruder screw arrangement requirements


The screw arrangement of the extruder must be determined according to the displacement of the extruder. Different specifications of the extruder have different requirements.


1. The left and right directions cannot be reversed;


2. The commissioning of the center is correct;


3. Ensure the plasticizing effect according to the product adjustment gap;


4. It must be concentric with the distribution box.


Ⅱ. The noise analysis of the barrel of the extruder screw


During the extrusion process, the extruder screw will make a sound when it rubs against the inner wall of the barrel. The reasons for this friction phenomenon are nothing more than the following four:


1. The assembly gap between the extruder screw and its supporting drive shaft is too large, and the two shaft centers are not concentric when rotating, and the error is too large.


2. The extruder screw is bent and deformed, and the straightness of the center line of the shaft is out of tolerance.


3. The end face of the extruder barrel and the flange end face of the base are connected, and the perpendicularity to the center line of the barrel cannot be guaranteed, and the error is large.


4. The extruder screw is assembled in the extruder barrel, and the error of the concentricity of the two parts is large.
