Coating stirring device

The utility model belongs to the field of stirring devices, and particularly relates to a coating stirring device which comprises a bottom plate, a support is fixedly connected to one side of the top end of the bottom plate. A rotating motor is started to drive a stirring rod to rotate, so that the stirring rod stirs raw materials, when the stirring rod rotates, a first gear is driven to rotate, the first gear drives a transmission belt meshed with the outer wall to rotate, the transmission belt drives a second gear on the other side to rotate, and when the second gear rotates, the second gear drives the stirring rod to rotate. When the stirring cylinder rotates, a connecting rod at the bottom and a reciprocating screw rod can be driven to rotate, a supporting column can support the bottom of the reciprocating screw rod, and when the reciprocating screw rod rotates, a nut arranged on the outer wall can be driven to move up and down on the outer wall of the reciprocating screw rod, so that the stirring cylinde
