[0002] Currently, powdered raw materials or products are widely used in various industries. The efficiency of powder transportation is very important for the production efficiency, product quality control and production environment improvement of various industries. Therefore, various industries pay special attention to the feeding and unloading devices of powder.

[0003] Currently, most devices used for loading and unloading powders employ hoppers or pipelines. Hopper loading and unloading devices typically use a funnel structure to guide and collect the powder. Pipeline loading and unloading methods often use high-pressure air to break the vacuum, allowing the powder to be transported by its own gravity.
