The invention discloses a stirring device for papermaking slurry. The stirring device comprises a base plate. Two first support rods are fixedly connected to the upper surface of the base plate. The opposite surfaces of two first support rods are both snapped to first bearings. Two first bearings sleeve first rotation shafts. The opposite ends of first rotation shafts are respectively fixedly connected to the front side and back side of a second bearing. The second bearing sleeves a stirring pot. Through the cooperation among a driving wheel, a driven wheel, a second motor, a first gear, a second gear, the second bearing, and a third bearing, the second motor drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate through a belt so as to rotate a stirring blade in the stirring pot, the first motor drives the second gear to rotate so as to rotate the stirring pot between the second bearing and the third bearing, thus slurry in the stirring pot can be moreevenly stirred, the slurry will not be accumulated in the dead angle, and the product quality is improved.
