Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to an automatic feeder for plastic polymer products. Background Art

[0002] Plastics processing refers to the process of transforming plastic raw materials into finished or semi-finished products through various processes and technologies. Plastics are widely used in various industries due to their lightness, corrosion resistance, and easy molding properties.

[0003] The Chinese patent publication number CN218196332U discloses an automatic feeding device for plastic processing, which solves the problem that plastic raw material particles on the current market will clump and stick together after being accumulated in a woven belt for too long.
