At the bottom of the driving wheel 22, a driven wheel 23 is provided. The driving wheel 22 and the driven wheel 23 are connected by a belt drive. Through the setting of the driving device 2, the mechanical energy required for the reciprocating device 3 to move can be provided, enabling it to operate. The reciprocating device 3 includes a connecting plate 31. Inside the cavity of the connecting plate 31, a lead screw 32 is threadedly connected. The right end of the lead screw 32 is movably connected to the right side of the cavity of the processing box 1. The left end of the lead screw 32 penetrates through the processing box 1 and extends to the outside of the processing box 1 and is welded to the right side of the driven wheel 23. On the front and rear sides of the connecting plate 31, sliding sleeves 33 are welded. Inside the cavity of the sliding sleeve 33, a sliding rod 34 is slidably connected. Both ends of the sliding rod 34 are welded to the inner wall of the processing box 1. Through the setting of the reciprocating device 3, the embossing device 4 can be driven to move back and forth. The embossing device 4 includes a fitting box 41. The top of the fitting box 41 is welded to the bottom of the connecting plate 31. At the top of the cavity of the fitting box 41, an electric push rod 42 is welded. The bottom of the electric push rod 42 is welded with a telescopic rod 43. The bottom end of the telescopic rod 43 penetrates through the fitting box 41 and extends to the outside of the fitting box 41 and is movably connected with a hot embossing roller 44. Inside the cavity of the telescopic rod 43, a spring 45 is welded. Through the setting of the embossing device 4, embossing operation can be carried out on the film, thereby increasing its aesthetics. The cooling device 5 includes a jet head 51. The left side of the jet head 51 is welded to the right side of the fitting box 41. The right side of the jet head 51 is communicated with a hose, and the end of the hose far from the jet head 51 penetrates through the processing box 1 and extends to the outside of the processing box 1 and is communicated with an induced draft fan 52. The bottom of the induced draft fan 52 is fixedly connected to the top of the processing box 1. Through the setting of the cooling device 5, after the embossing operation is completed, the film can be quickly cooled, thereby preventing the film from being stretched during the coiling of the coiling device 9. Through the setting 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 wheels 7, the feeding device 8 and the coiling device 9, the effect of preventing the film from being stretched is achieved, and at the same time, the problem that the existing embossing machine basically presses patterns on the film with a hot embossing roller, and because the thickness of the film is very thin, it is very easy to be stretched and deformed during transmission due to the heating effect of the hot embossing roller, increasing the rejection rate is solved.

[0018] In use, the entire device is powered by an external power supply and started through a peripheral controller. The film feeding device 8 and the coil feeding 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 coil feeding 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 provides a certain buffer. At the same time, the output shaft of the servo motor 21 drives the driving wheel 22 to rotate, the driving wheel 22 drives the driven wheel 23 to rotate through the belt, and the driven wheel 23 drives the lead screw 32 to rotate. Under the action of the lead screw 32, the connecting plate 31 moves to the left. When the connecting plate 31 moves, the sliding sleeve 33 and the sliding rod 34 limit and support it to enable stable movement. 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, and the hot pressing roller 44 performs embossing operations on the surface of the film. When the hot pressing roller 44 moves to the left, at this time, the electric push rod 42 drives the hot pressing roller 44 to disengage from the film through the telescopic rod 43. At this time, the coil feeding device 9 winds the film again. Then the servo motor 21 rotates in reverse to return the embossing device 4 to its original position for re-embossing. At the same time, the air blower 52 injects cold air into the air jet head 51 through the hose. The air jet head 51 moves with the accessory box 41 and cools the embossed film. By repeating the above actions, the effect of preventing the film from stretching is achieved.

[0019] In summary, for the embossing mechanism for the film, through the cooperation 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 film feeding device 8 and the coil feeding device 9, it solves the problem that in the existing embossing machine, basically the hot pressing roller presses patterns on the film. Since the thickness of the film is very thin, it is very easy to stretch and deform during transmission due to the heating effect of the hot pressing roller, increasing the rejection rate.

[0020] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
