Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to an automatic feeding device for a plastic wire box raw material drying hopper. Background Technology

[0002] In the production process of plastic wire boxes, the drying of raw materials is one of the key steps to ensure product quality, and the feeding efficiency and stability of the drying hopper directly affect the continuity of subsequent processing. Currently, belt conveyors are widely used as the core conveying equipment for automatic feeding of drying hoppers due to their simple structure, large conveying capacity, and strong adaptability.

[0003] However, in actual operation, when belt conveyors transport raw materials for plastic boxes (such as modified plastic granules, recycled plastic fragments, etc.), due to factors such as electrostatic adsorption, residual moisture, or irregular shape on the surface of the raw materials, some raw materials tend to adhere to the conveyor belt surface and cannot completely fall into the drying hopper. These adhered raw materials cause material waste and increase production costs. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides an automatic feeding device for a plastic wire box raw material drying hopper, which solves the technical problem in the prior art that raw materials are easily attached to the surface of the conveyor belt during the feeding process, resulting in raw material waste.
