[0003] At present, in the process of processing and producing PET plastics, an extrusion feeding device is an important structure for conveying the raw materials of PET plastics into a plastic extruder for processing. However, the inventors have found that the conventional PET plastic extrusion feeding is prone to raw material accumulation and blockage, resulting in poor feeding effect. Therefore, we propose a PET plastic extrusion feeding device. Utility Model Content
