AI Technical Summary
During the production of resin profiles, voids and cavities can easily form in the hopper of the raw materials, causing excessive air to enter the extruder, affecting the melt quality and the workload of the subsequent venting section.
The system employs a flow guide hood and lifting mechanism in conjunction with a dredging component. By rotating the hood, the raw materials are evenly spread and mixed within the hopper, and by using the dredging component to break up voids and cavities, the continuous flow of materials is ensured.
It effectively avoids the formation of voids and cavities in the raw materials within the hopper, reduces air entry, and improves the uniformity of material mixing and the working efficiency of the extruder.
