Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. With the development of science and technology, lithium batteries have now become the mainstream, so the requirements for the production and processing of batteries are also higher.

[0003] However, in the existing production process formula, the feeding method of the powder material is manual feeding. Because there are many types of powder materials and they cannot be confused with each other, operators often make mistakes in feeding the powder materials into the wrong mixing tank, resulting in problems such as unqualified products and waste of raw materials.

By setting an openable and closable sealing plate assembly at the top of the feeding port of the mixing tank, when manual feeding is carried out, the feeding port is closed, and after the feeding is completed and confirmed to be correct, the feeding port is opened and the material is scraped into the tank, which can prevent problems such as unqualified products and waste of raw materials caused by manual feeding errors.

[0006] To achieve the above purpose, the utility model is implemented by the following technical solutions.

A supporting rod 26 is fixedly arranged inside the fixing frame 25, and the supporting rod 26 is rotatably connected to the stirring blade 28 through a connecting sleeve 27. When the rotating shaft 22 drives the stirring rods 23 to rotate, the fixing rods 24 will also be driven to rotate. When stirring the liquid in the mixing tank 1, the stirring blade 28 can be driven to rotate under the action of the liquid, so as to realize the full and uniform slurry mixing of the lithium battery.
