Feeding mechanism of double-screw extruder

The invention relates to the technical field of extruder production, in particular to a feeding mechanism of a double-screw extruder, which comprises a feeding barrel and a feeding assembly, a discharge port at the bottom of the feeding barrel is fixedly connected with a feed port of an extrusion barrel, and the feeding assembly is mounted at the upper end of the feeding barrel and comprises a plurality of groups of feeding discs. A plurality of feeding channels are formed in the feeding discs at intervals in the circumferential direction of the feeding discs, the upper sealing plate and the lower sealing plate are each provided with a feeding port and a discharging port, the feeding ports are fixedly connected with the corresponding feeding pipelines, and the feeding ports and the discharging ports are not coaxial in the vertical direction. The intermittent transmission assembly drives the material conveying channels on the multiple sets of feeding discs to alternately communicate with the feeding port and t
