The invention discloses a coating dispersion machine with a cooling function. The coating dispersion machine comprises a support, a dispersion barrel, a top plate and a stirring mechanism fixed on thetop plate, wherein the stirring mechanism comprises a first motor and a stirring shaft, a lifting mechanism is also fixed on the top plate and comprises hydraulic cylinders fixed on the top plate anda controller for controlling the hydraulic cylinders to move, and the hydraulic cylinders and the controller are fixed on the support; a pressure inductor is arranged at the tail end of the stirringshaft and electrically connected with the controller; a turning mechanism is arranged at the bottom of the dispersion barrel. The dispersion barrel rotates to be matched with the stirring mechanism, the dispersion efficiency is improved, meanwhile, a ball drives the dispersion barrel to rotate, and loss of the dispersion barrel can also be reduced; a water storage cavity is formed, and the technical problems that coating raw materials produce heat during dispersion and stirring and can influence the production quality of a coating are solved.
