Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a continuous feeding device for powder materials. Background Art

[0002] Continuous feeding refers to the continuous feeding of raw materials or products according to the set parameters during the uninterrupted production process to ensure uninterrupted production. At present, most of the domestic powder feeding hoppers adopt an inverted cone structure, and most of the common feeding hoppers now adopt a pull-out baffle plate. When feeding is required, the baffle plate is pulled outward to open the discharge port of the feeding hopper for feeding. However, when feeding, the existing powder feeding hopper is prone to blockage due to excessive density caused by the powder stacking together, which requires frequent manual unblocking, which not only affects production efficiency, but also increases the cost of manual maintenance. In addition, the powder is also easy to adhere to the inner wall of the feeding hopper, resulting in powder waste. Utility Model Content
