After searching, the patent publication number CN218358800U discloses "a new glue supply and stirring container", including a container body and a stirring device. The container body is provided with a holding space inside. The stirring device includes two rotating shafts and two corresponding stirring paddles. The two constitute a planetary stirring device, which is used to rotate and stir when supplying glue to avoid the glue from settling, thereby ensuring the consistency of the glue at any time and any position, and significantly improving the stirring efficiency of the glue; it also includes a number of electromagnetic filtering devices, which are arranged at intervals on the inner wall of the container body. When powered on during the glue dispensing process, magnetic force can be generated, thereby adsorbing tiny magnetic impurities in the glue into its internal mesh filter element, which can prevent magnetic impurities from scratching and damaging the coating roller in subsequent coating operations, and can prevent magnetic impurities from being mixed in the glue layer and causing adverse effects on the glue layer structure and its application.

[0003] In the prior art, in order to prevent the particles from settling, it is necessary to continuously stir the glue at the bottom by driving the stirring rod, and to pressurize the inside of the mixing drum with air to force the stirred glue out through the discharge port. Therefore, a sealing ring is provided between the driving shaft and the drum for sealing. However, during the long-term rotation of the driving shaft, the sealing ring is prone to wear, resulting in a decrease in the overall sealing performance, which affects the normal use of the equipment.
