Description

Technical Field

[0001] This application relates to the field of food processing equipment technology, and in particular to a breakage prevention feeding mechanism for fragile materials. Background Technology

[0002] In the food processing industry, addressing the issue of fragile materials is a common challenge. Traditional weighing and bagging mechanisms often lack specific designs to accommodate these fragile materials, frequently leading to damage during transport due to excessive impact. This not only reduces product yield but also increases production costs. In recent years, with consumers' increasing demands for food quality, effectively protecting fragile materials has become a key focus for the industry. While some improvements have been implemented, such as slowing down conveyor belts and adding cushioning pads, their effectiveness is limited and fails to fundamentally solve the problem.

[0003] To reduce breakage of fragile materials during the feeding process, existing technologies employ a deceleration method, where a deceleration device is installed before the feeding port to allow the material to descend slowly. While this method can reduce breakage to some extent, its effectiveness is not ideal due to material accumulation effects. A second approach is the soft-landing design, which involves adding soft materials, such as sponges or rubber pads, inside the receiving container to absorb impact. However, this method tends to cause material adhesion, making cleaning difficult and unsuitable for continuous production lines.

[0004] While existing technologies can alleviate the problem of breakage of fragile materials to some extent, they still have significant limitations. Deceleration during discharge fails to address secondary impacts caused by material accumulation; the soft-landing design increases cleaning difficulty and is unsuitable for large-scale industrial production.
