[0002] The powder packaging process in the lithium battery industry usually uses gas conveying and separators to achieve powder conveying and separation operations. The separated materials first enter the large storage tank for buffering. A packaging component is provided under the storage tank, and the packaging component is used to bag the powder in the storage tank, which is circulated. During long-term use, the powder in the storage tank is prone to accumulation, especially when the powder is not dry enough, it is easy to agglomerate inside the storage tank, resulting in the powder being unable to be discharged smoothly from the storage tank outlet. In this case, the operator needs to remove or crush the agglomerates in the storage tank before continuing the packaging operation, which makes the packaging operation unable to be carried out continuously, reducing the packaging efficiency. At the same time, it also brings a large labor load to the operator.

[0003] Therefore, it is urgent to provide a dust bagging device that can ensure the continuous packaging operation, which can effectively reduce the workload of operators while improving the packaging efficiency. Summary of the invention
