[0002] In plastic extrusion molding equipment, plastic sheet extruder is usually called the main machine, and its supporting subsequent equipment plastic extrusion molding machine is called auxiliary machine. After more than 100 years of development, plastic sheet extruder has evolved from the original single screw to twin screw, multi-screw, and even screwless models. It relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material, and then form it through the die. During the molding process, a feeding device is usually required to carry out uninterrupted feeding to keep the extruder discharge continuous and improve the operating efficiency.

[0003] The existing extruder feeding structure generally feeds materials through a hopper, and the existing feeding hopper can only store the raw materials and feed them by the raw materials' own weight.
