The top of the accessory box 41 is welded to the bottom of the connecting plate 31. The top of the inner cavity of the accessory box 41 is welded with an electric push rod 42. The bottom of the electric push rod 42 is welded with a telescopic rod 43. The bottom end of the telescopic rod 43 penetrates the accessory box 41 and extends to the outside of the accessory box 41. It is movably connected with a hot pressing roller 44. The inner cavity of the telescopic rod 43 is welded with a spring 45.

The bottom of the induced draft fan 52 is fixedly connected to the top of the processing box 1. Through the arrangement of the cooling device 5, the film can be quickly cooled after the embossing operation is completed, thereby preventing the film from stretching due to the winding device 9. Through the arrangement of the processing box 1, the driving device 2, the reciprocating device 3, the embossing device 4, the cooling device 5, the workbench 6, the guide wheel 7, the unwinding device 8 and the winding device 9, the effect of preventing the film from stretching is achieved, and at the same time, the problem that the existing embossing machine basically embosses patterns on the film with a hot pressing roller is solved. Since the thickness of the film is very thin, it is easy to be stretched and deformed due to the heating effect of the hot pressing roller during transportation, thereby increasing the scrap rate.

[0020] When in use, the entire device is powered by an external power supply and started by an external controller. The unloading device 8 and the winding device 9 pass the film through the processing box 1. At this time, the hot pressing roller 44 is heated. After reaching the specified temperature, the winding device 9 stops winding. At this time, the electric push rod 42 drives the telescopic rod 43 to move downward, and the telescopic rod 43 drives the hot pressing roller 44 to move downward, and the spring 45 performs a certain buffer.

The connecting plate 31 moves to the left under the action of the screw rod 32, and when the connecting plate 31 moves, the sliding sleeve 33 and the sliding rod 34 are used for it. The limiting support enables it to move stably. At the same time, the connecting plate 31 drives the accessory box 41 to move to the left. The accessory box 41 drives the hot pressing roller 44 to move to the left through the electric push rod 42 and the telescopic rod 43. The hot pressing roller 44 embosses the surface of the film. When the hot pressing roller 44 moves to the left, the electric push rod 42 drives the hot pressing roller 44 to separate from the film through the telescopic rod 43. At this time, the winding device 9 rewinds the film again, and then the servo motor 21 reverses to return the embossing device 4 to perform embossing again. At the same time, the induced draft fan 52 injects cold air into the nozzle 51 through the hose. The nozzle 51 moves with the accessory box 41 and cools the embossed film. The above actions are repeated to achieve the effect of preventing the film from stretching.
