AI Technical Summary
Existing extrusion screws are not efficient enough in converting materials from the solid phase to the liquid phase, and it is necessary to improve the material conversion efficiency.
Auxiliary screw ribs and second auxiliary screw ribs are introduced into the screw rib structure of the extrusion screw. The width and height of the screw ribs are adjusted to enhance the mixing and pushing effect. The material flow is optimized through the spiral groove and single screw rib structure. The design of screw rib spacing and groove depth is combined to adapt to changes in material state.
It improves the conversion efficiency of materials from solid to liquid phase, ensures material uniformity and extrusion output, and improves the plasticizing and melting effects of materials.
