This utility model discloses a multi-color continuous printing device, which comprises a film blowing machine, a plurality of printing machines arranged side by side, and a winding mechanism. Each printing machine is internally provided with a traction mechanism for drawing the film. The film blowing machine comprises a hot-melt extruder, a blowing head connected with the hot-melt extruder, a frame body, and a herringbone plate arranged on the frame body above the blowing head. The frame body is also provided with a plurality of guide rollers for guiding the film to the printing machine adjacent to the film blowing machine. Dyes of different colors are filled in the plurality of printing machines; raw materials are melted in the hot-melt extruder and then extruded into the blowing head to be blown into a tubular film, which is further folded by the herringbone plate, guided by the guide rollers and fed into the printing machines. The film continuously passes through the plurality of printing machines, so that characters and patterns of different colors can be continuously printed on the film, and the film is finally wound up by the winding mechanism. The device completes printing in one step without stopping for material replacement, and the printing efficiency is significantly improved.
