In the process of chemical production and processing, some chemical raw materials need to be mixed to facilitate subsequent processing and manufacturing.

[0003] In traditional mixing devices, some water-based adhesives or resin raw materials can easily splash onto the connection between the container and the sealing cap during the mixing process. These attached materials no longer participate in the subsequent mixing process. Over time, the moisture in these attached materials gradually evaporates, leading to drying and solidification, which makes it difficult to open the cap, increases the difficulty and labor intensity of the operators, and reduces production efficiency.
