The invention discloses a metalized film processing vacuum coating machine for an electric container. The metalized film processing vacuum coating machine comprises a base, a vacuum machine, a conveying device, sealing devices, a coating box, a cathode, a target, an anode and an argon ion machine. The bottom of the coating box is connected to the base, the vacuum machine and the argon ion machineare arranged on the base and communicate to the bottom of the coating box, the cathode and the anode are separately arranged at the upper and lower ends in the coating box, the bottom of the cathode is connected to the target, the top of the conveying device penetrates the coating box transversely, the sealing devices are separately mounted at two ends of the coating box, the sealing devices are matched with the conveying device, and the conveying device comprises a conveying wheel, a conveyor belt, a gravity wheel, a guide bar and a bracket. The metalized film processing vacuum coating machine has the beneficial effects that the coating box can be sealed by matching switching of the sealing devices with the conveyor belt, and workpieces can be conveyed continuously through the conveyor belt, and compared with workpiece taking and placing overlapped action, the shut down time can be shortened and the work efficiency can be improved.
