Support plates 10 for supporting the conveyor belt 3 are symmetrically arranged on the left and right sides inside the frame 1. A material barrel 4 is arranged on the right side of the frame 1, and the material barrel is supported by a column. A discharge port at the lower end of the material barrel 4 is connected to a discharge pipe 5, and a gear pump 6 is connected to the discharge pipe 5.

Place the filling barrels on the conveyor belt in sequence and at equal intervals. The frontmost filling barrel is located below the outlet of the discharge pipe. The servo motor drives the alternating drive component. The alternating drive component first rotates the gear pump to make the discharge pipe quantitatively output the metal surface treatment agent into the filling barrel. After the gear pump stops, it drives the transmission roller to make the conveyor belt transport the filling barrels for a fixed distance, so that the next filling barrel is located below the outlet of the discharge pipe.
