Zusammenfassung:The double-screw extrusion mechanism comprises a charging barrel and a screw mechanism, the charging barrel is arranged in the middle of the inner side of the extruder, and the screw mechanism is located on the inner side of the charging barrel. The feeding mechanism is used for ensuring that plastic particles uniformly enter the charging barrel, the heat preservation mechanism is used for ensuring that the temperature in the charging barrel is kept constant, the turbulent flow mechanism is used for uniformly stirring materials, the feeding mechanism is located at the upper part of one end of the charging barrel, and the heat preservation mechanism is located in the charging barrel; the plastic particle feeding device has the beneficial effects that the structure is simple, the feeding mechanism is arranged, so that plastic particles can uniformly enter the charging barrel in batches, the heat preservation mechanism is arranged, the charging barrel can be heated according to actual use requirements, the tempe
