The plurality of feed rods 31 are threadedly connected to facilitate maintenance. When part of them is damaged, only the damaged part needs to be removed and replaced, thereby reducing the maintenance cost. The screening filter 4 is woven by heating wire, so that the screening filter 4 can screen the raw materials while heating and melting the unmelted materials.

[0020] Working principle: When the utility model is in use, the feed rod 31 is connected to an external power source through a coupling, and the working temperature of each screening filter 4 is set according to the melting temperature of the raw material. When in use, the raw material is added to the shell 1 through the feeding pipe 2, and the feed rod 31 is driven to rotate by an external driving device, thereby driving the spiral feeding blade 32 to rotate, and the raw material is driven to move by the rotating spiral feeding blade 32. When the raw material is conveyed, the material is mixed by the mixing protrusion 33. While the raw material is screened by the screening filter 4, the incompletely melted raw material is heated and melted to avoid the presence of incompletely melted raw materials in the extruded molten plastic, which affects the quality of the environmentally friendly plastic sheet.
