The present invention provides a shoe cover machine. A mounting frame with a PVC heat shrinking film is arranged in the shell of the shoe cover machine; the heat shrinking film is conveyed to a pedal through a conveying device; a film covering device is arranged in the shoe cover machine and a heating device is arranged in the film covering device. The heating device comprises a hot air cavity; a hot air duct is arranged in the hot air cavity; the pedal seals the outlet of the hot air cavity or the hot air duct; the air inlet of the hot air duct is provided with a fan; a heater is arranged in the hot air duct; the outside of the hot air cavity is provided with a heat insulating layer; a repositor is arranged in a pedal lifting mechanism; a control system controls the fan and the temperature of the hot air in the hot air cavity. As the hot air is pre-stored in the hot air duct, the film covering device of the shoe cover machine has rapid film covering and high work efficiency.
