Material pumping device of lithium battery stirrer

The utility model discloses a material pumping device of a lithium battery stirring machine, which comprises a material pumping seat matched with a sealing machine cover of the stirring machine and mounted in a rotary inner barrel, a piston head assembly arranged in the material pumping seat, a piston rod connected with the piston head assembly, and a piston cylinder mounted on the material pumping seat and used for controlling the reciprocating motion of the piston rod, a material pumping channel used for material pumping is arranged in the material pumping base, and the piston air cylinder drives the piston rod to do telescopic motion so that the piston head assembly can open or close the material pumping channel. According to the technical scheme, the piston cylinder of the material pumping device drives the piston head assembly to slide up and down in the inner cavity of the material pumping seat, the conical sealing ring below the piston head assembly seals the material pumping opening and closes the dis
