Description

Technical Field

[0001] This invention belongs to the field of automatic feeding, specifically relating to a terminal feeding device and its usage method. Background Technology

[0002] In the food and chemical industries, the feeding process for ton-bag packaged powders or granules often involves forklifts transporting the bags to the feeding point, where workers manually hang the bags on a lifting frame, attach the frame to an electric hoist, and use a control handle to lower the bag to a suitable height. The bag is then moved horizontally to a position directly above the feeding point, and the bag is lowered again. The outer discharge strap is manually untied, the inner bag pulled out, and the bag is secured to a clamp or feeding port before the inner bag strap is untied. The material inside the bag is then released into the designated container under gravity. Simultaneously, the bag needs to be continuously tapped to ensure the material falls smoothly. This entire feeding process requires manual intervention at every stage, resulting in high labor intensity, high labor costs, and low efficiency. Feeding also easily generates dust, and when emptying the bags, any remaining material can easily spill into the air, causing environmental pollution and potential injury.

[0003] The existing ton bag feeding method is prone to powder leakage, which can cause environmental pollution and injury to personnel. The existing ton bag feeding method requires manual participation throughout the process, which is labor-intensive, has high labor costs, and is inefficient. Summary of the Invention
