High-speed coating machine

The embodiment of the invention discloses a high-speed coating machine, and aims to solve the problem of the conventional coating equipment that due to limitation of drying rate in coating, if the coating speed is increased, a baking oven needs to be lengthened, and the factory building area needs to be increased. The high-speed coating machine comprises an unwinding device, a first coating device, a double-layered baking oven device, a second coating device, an infrared drying device, a traction device and a winding device; an unwinding opening of the unwinding device, a coating machine head I of the first coating device, a first baking passage of the double-layered baking oven device, a coating machine head II of the second coating device, a second baking passage of the double-layered baking oven device, the infrared drying device, the traction device and a winding opening of the winding device form a coating passage for conveying base materials through a plurality of guide rollers in sequence.
