Shoe cover machine and film overlay method using shoe cover machine

Abstract

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.

Description

Technical field: [0001] The invention relates to a shoe cover machine and a film covering method with the shoe cover machine. Background technique: [0002] At present, some shoe cover machines use the principle of thermal shrinkage of the heat shrinkable film to fix the heat shrinkable film on the shoes. Just proposed a kind of " automatic shoe cover machine " as No. 03233497.4 of Chinese patent. In this technical solution, the automatic shoe cover machine includes: heat-shrinkable film roll, film feeding roller, upper cutter, lower cutter, and pedals are installed in the box in sequence, and a U-shaped heating device is located below the pedal, and the pedal is fixedly connected to the pedal. Rod, the bottom of the pedal rod is connected with the return spring, the pedal rod is connected with the lever, and the upper cutter or the lower cutter is connected with one end of the lever. It wraps the heat shrinkable film on the user's shoes. But it has the following disadvan...

AI Technical Summary

Problems solved by technology

[0004] 2. When the above-mentioned automatic shoe cover machine transports the heat shrinkable film, electrostatic adsorption will occur, and the stability of the heat shrinkable film transport process is not ideal, which affects the working performance of the shoe cover machine

After wrapping a shoe cover, the user must wait for the U-shaped heating device to cool down before the conveying mechanism can send the heat-shrinkable film to the top of the pedal again, otherwise the heat-shrinkable film will automatically shrink, making the next shoe cover to wait too long

[0006] 4. Since the above scheme uses a U-shaped heating device to directly shrink the heat-shrinkable film, there is no hot air in a specific direction, which makes the wrapping effect of the heat-shrinkable film unsatisfactory
