Description

Technical Field

[0001] The utility model relates to the technical field of shoe film machines, in particular to a three-dimensional shoe film coating machine. Background Art

[0002] The traditional shoe film machine is a linear film discharger. After the heat shrink film is transported to the pedal area, the film is cut flatly by a blade moving up and down. The foot steps on the pedal in the pedal area, and the pedal sinks to release the hot air outlet. The middle of the heat shrink film is turned up along with the pedal sinking, and the edge is wrapped around the bottom of the shoe under hot air blowing, as shown in Chinese patent No. 200980124358.2, named shoe cover machine and method for film coating using shoe cover machine.

[0003] like Figure 1 As shown, because the pedal in the traditional shoe film machine sinks to a small height, the height of the heat shrink film edge is also small, and the heat shrink film will shrink longitudinally under the action of hot air, further reducing the coverage height of the heat shrink film. Therefore, the heat shrink film sleeve formed after heat shrinkage has a low wrapping height on the shoe surface or can only wrap the outsole, making the heat shrink film sleeve easy to fall off during walking and pulling.

[0004] Therefore, in order to solve the problem that the heat shrinkable film shrinks downward during hot air blowing and reduces the wrapping height, this case proposes a three-dimensional shoe film wrapping machine that reduces the longitudinal shrinkage of the heat shrinkable film and increases the wrapping height of the heat shrinkable film.

[0016] A further improvement is that: the heating wire cover is integrally provided with an inverted eight-shaped guide slope on the inner side surfaces on both sides of the rear end of the pressing panel for guiding the three-dimensional free end of the heat shrink film after hot-melt clamping to be discharged centrally to the pressing panel, and an air flow channel for air circulation is opened on the heating wire cover between the guide slopes.

[0021] By adopting the above technical solution, the beneficial effects of the utility model are:

[0022] In this case, the left and right sides of the heat shrink film are driven to flip up and bond and clamp off by the hot cutting clamp, which simplifies the clamping structure and maximizes the upward flipping of the heat shrink film, thereby increasing the height of the heat shrink film covering the shoe body, increasing the wrapping area of ​​the heat shrink film sleeve, and preventing the heat shrink film sleeve from actively detaching from the shoe body; when removing the heat shrink film, it is only necessary to tear it to both sides along the hot clamping track to easily remove the heat shrink film sleeve. Under the action of the extension part and the guide block, the heat shrink film is discharged in an arc shape along the guide extension spacing first longitudinally and then transversely, so that when the free end of the heat shrink film is restricted by stepping on the shoe body, the two sides still have the deformation amount of flipping up to facilitate thermal clamping and forming a three-dimensional ship-shaped shape, and the guide block is only set in the middle of the extension part, and the two sides of the guide block form a flip-up avoidance part for the heat shrink film to flip up and deform. At the same time, the guide block limits the upward movement of the middle part of the heat shrink film, which is conducive to making the flip-up height of both sides of the heat shrink film consistent.

[0023] A further beneficial effect is that the arrangement of the film pushing roller or the film pushing wheel prevents the heat shrink film from accumulating in the guide extension spacing, which is beneficial for the heat shrink film to be smoothly discharged.

[0024] A further beneficial effect is that in this case, the heat shrink film is already folded upward when it enters the pressing panel, so there is no need to set a sinking pedal on the pressing panel, which simplifies the internal structure of the shoe film machine. At the same time, the U-shaped heating wire cover is used to set the heating wire on the upper surface of the pedal panel, which simplifies the hot air channel inside the shell, helps to reduce the longitudinal height of the shoe film machine, and makes the shoe film machine more compact.

[0025] A further beneficial effect is that after the heat shrink film is cut off, the heat shrink film can also be driven by the user's heel to move toward the rear end of the stepping panel, but the user experience is poor. Therefore, in this case, an air outlet channel is set above the heat shrink film, and the air outlet channel is used to send air to the three-dimensional tip of the heat shrink film, so that the wind force is gathered in the three-dimensional tip and easily pushes the free end of the heat shrink film to automatically flatten toward the stepping panel. It is convenient to use, simple in structure, and has a good user experience.

[0026] A further beneficial effect is that the inverted eight-shaped guide slopes arranged on both sides of the rear end of the pressing panel are conducive to the centering of the boat-shaped three-dimensional end of the heat shrinkable film on the pressing panel, making it convenient for the user to step on the middle position of the heat shrinkable film, and is conducive to the smooth installation of the heat shrinkable film cover on the shoe body after heat shrinkage.
