Description

Technical Field

[0001] The utility model relates to the technical field of screw high-speed packaging machines, in particular to a powder dispensing component for a screw high-speed packaging machine. Background Art

[0002] The screw filling machine uses the rotation of the screw to drive the material forward in the screw groove, and sends the material into the container through the feed port to complete the filling operation. Multiple spiral screws in the screw groove are nested with each other and rotate in opposite directions. The packed material is pushed forward along the spiral lines on different spiral lines to complete the quantitative filling. At the same time, the screw filling machine can also automatically compress the material during the filling process to ensure that the packed material is dense, free of bubbles and lumps, thereby improving production efficiency.
