[0002] A twin-screw hemp clamp is a mechanical device used for material handling and processing. It typically consists of two meshing screws that use rotational motion to convey and mix materials.

[0003] Currently, the corner conveying structure of the twin-screw hemp clamp has the following drawbacks: Due to the high mixing intensity of the twin-screw hemp clamp, when there is a large difference in density and specific gravity of certain materials, it is easy to produce a bias phenomenon; this means that the material may shift to one side during the handling process, resulting in uneven mixing and affecting the quality of the final product; in addition, the twin-screw hemp clamp generates a lot of noise during the mixing process, and the investment cost of the entire device is high.

[0004] Therefore, it is particularly necessary to provide a twin-screw corner handling mechanical device for hemp clamps that has a reasonable structural design, high handling efficiency, low cost, and reduced noise. Summary of the Invention
