Description

Technical Field

[0001] This utility model relates to the technical field of fine powder feeding stations, specifically to a leak-proof structure for fine powder feeding stations. Background Technology

[0002] A fine powder feeding station is a device used to process small bags of powdery materials and achieve dust-free material feeding. Personnel place the bags on the platform and open them manually or automatically. The material falls into the hopper by gravity and is connected to the conveying unit through the conveying pipe at the bottom, effectively outputting the material to the designated location. As an important piece of equipment for achieving dust-free and automated feeding in modern industrial production, its feeding operation is directly related to production efficiency, product quality, and working environment safety.

[0003] Existing feeder leakage prevention structures generally use the inner cylinder of the feeder for sealing. During the feeding process, the powder material has good flowability and is in a state similar to a fluid. The inner cylinder of the feeder is not sufficiently sealed, and leakage is likely to occur when the powder material is fed. This increases the unit consumption of the production product, reduces the leakage prevention effect of the fine powder feeder, and cannot meet the usage requirements. Utility Model Content
