AI Technical Summary
Existing extrusion screws cannot be used according to different segments during operation, and the plastic is not mixed evenly during the melting process, which affects extrusion efficiency and quality.
A novel conductive plastic extruder screw structure was designed. By combining a transmission mechanism and an agitation mechanism, the size of the main shaft at different positions and the agitation of the plastic are achieved, ensuring the uniformity of the melting process.
It improves the efficiency of the transfer process and the mixing effect, avoids uneven heating of plastics, and enhances the overall mixing quality.
