Mixed material buffer tank for chromium plating

The utility model relates to the technical field of chromium plating, and discloses a mixed material buffer tank for chromium plating, which comprises a shell, an observation window is fixedly mounted on the front side of the shell, a collection box is mounted on one side of the observation window, a box door is mounted on one side of the collection box through a hinge, and a sealing gasket is fixedly mounted on the other side of the box door. According to the mixed material buffer tank for chromium plating, through cooperative arrangement of a servo motor, a transmission rod, a rotating rod and stirring blades, when the mixed material buffer tank is used, the servo motor drives the transmission rod to rotate, then the transmission rod drives the rotating rod to rotate, and then the rotating rod drives the stirring blades to rotate, so that the effect of uniformly mixing and stirring a plating solution is achieved; through cooperative arrangement of the first slag discharging opening, the collecting box and t
