Uniform subpackaging mechanism for water reducer packaging

The uniform subpackaging mechanism comprises a supporting bottom plate, a support and a supporting top plate, the support is fixedly installed on the supporting bottom plate, the supporting top plate is fixed to the top wall of the support, a sliding groove is formed in the supporting top plate in an embedded mode, a sliding plate is arranged on the sliding groove in a sliding mode, a subpackaging box is fixed to the sliding plate, and the subpackaging box is fixed to the supporting bottom plate. And a rotary knocking blanking mechanism is arranged on the supporting top plate close to the top wall of the sub-packaging box. The utility model belongs to the technical field of water reducing agent production, and particularly relates to a rotary knocking blanking mechanism which knocks a sub-packaging box while rotating the sub-packaging box, shakes off a water reducing agent attached to the inner wall of the sub-packaging box, effectively prevents the water reducing agent from being attached to the inner wall o
