[0002] Traditional hot stamping equipment has certain limitations. In the printing process, to improve production efficiency, two sets of patterns are usually set on a roll of printing film on the width and printed simultaneously. Correspondingly, two sets of hot stamping film are also needed in the hot stamping process to match the two sets of patterns on the printing film. However, in actual production, when the order quantity of printing film is small, one roll of hot stamping film is sufficient to complete the hot stamping work. Nevertheless, due to the process requirement that two sets of hot stamping film must be used at the same time, a roll of hot stamping film cannot be completely used, resulting in waste. Since the hot stamping film used for each hot stamping may be different, the remaining hot stamping film is difficult to reuse in the next order, further aggravating the problem of material waste.

That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0017] according to Figures 1-4 As shown, a hot stamping film flipping device includes a hot stamping assembly. The hot stamping assembly includes a supporting shell 11, within which a middle frame 12 is disposed. The middle frame 12 is a frame composed of multiple rectangular connecting rods arranged in a rectangular pattern. A hot stamping film unwinding device 2 and a hot stamping film rewinding device 3 are disposed on both sides of the middle frame 12. A hot stamping film flipping device 4 is disposed within the middle frame 12. The hot stamping film flipping device 4 is used to offset the position of the hot stamping film, allowing a roll of hot stamping film to be stamped on patterns on both sides. The hot stamping film flipping device 4 includes a pair of inclined air rollers, with adjusting connecting blocks 5 disposed at both ends of the air rollers. The air rollers are set in the middle frame 12 via the adjusting connecting block 5. The air rollers include a first air roller 41 and a second air roller 42, which are offset from each other in the middle frame 12. A feed roller 43 is provided on one side of the air rollers. The feed roller 43 is located close to the support housing 11 on one side and is positioned between the first air roller 41 and the second air roller 42. The hot stamping assembly also includes a hot stamping pressure roller 13 and a peeling device 14. The hot stamping pressure roller 13 is located at the bottom near the hot stamping film flipping device 4, and the peeling device 14 is located at the bottom of the hot stamping film winding device 3.

[0018] The middle frame 12 is provided with a guide rail 15 facing outwards. The hot stamping film unwinding device 2 and the hot stamping film winding device 3 are movably mounted on the middle frame 12 via the guide rail 15. Each of the hot stamping film unwinding device 2 and the hot stamping film winding device 3 is provided with a pair of side plates. The winding roller or unwinding roller of the hot stamping film unwinding device 2 and the hot stamping film winding device 3 is located between the side plates, and the driving device for driving is located outside the side plates. The side plates include an unwinding device side plate 21 and a winding device side plate 31. An adjusting screw is provided on the side plate, and the adjusting screw includes an unwinding adjusting screw 22 and a winding adjusting screw 31. Rod 32, one end of the adjusting screw extends out of the support housing 11 and is connected to a drive motor. The drive motor includes an unwinding side plate motor 23 and a rewinding side plate motor 33. The drive motor drives the adjusting screw to rotate, which can control the lateral position of the hot stamping film unwinding device 2 or the hot stamping film rewinding device 3 in the support housing 11, thereby adjusting the hot stamping position of the hot stamping film on the printing film. The hot stamping film unwinding device 2 and the hot stamping film rewinding device 3 are each provided with two sets of unwinding or rewinding positions, including a first unwinding position 24 and a second unwinding position 25, and a first rewinding position 34 and a second rewinding position 35 for rewinding the hot stamping film.

[0019] The adjusting connecting block 5 includes a base 51, an L-shaped plate 52 fixedly mounted on the top of the base 51, a movable block 53 disposed in the base 51, and an adjusting screw 54 passing through the L-shaped plate 52. The adjusting screw 54 passes through both the L-shaped plate 52 and the movable block 53. A locking device 55 is also provided on one side of the L-shaped plate 52. The two ends of the air rod are rotatably mounted on the movable block 53. Rotating the adjusting screw 54 allows the movable block 53 to rise and fall within the base 51 for fine-tuning. Simultaneously, adjusting the connecting blocks 5 at both ends allows for fine-tuning of the height of the air roller. Adjusting one end of the connecting block 5 alone allows for adjusting the angle of the air roller. By adjusting the height and angle of the air roller, the position of the hot stamping film after passing over the first air roller 41 and landing on the printing film can be changed. The locking device 55 is a bolt passing through the L-shaped plate 52, with one end pressing against the adjusting screw 54 and the other end having a handle. Rotating the locking device 55 can fix the movement of the adjusting screw 54.

[0020] The bottom of the hot stamping film unwinding device 2 and the hot stamping film rewinding device 3 are respectively provided with a first feed roller 26 and a second feed roller 36. The first feed roller 26 and the second feed roller 36 are provided on the support housing 11. The first feed roller 26 is provided on one side of the hot stamping pressure roller 13, and the second feed roller 36 is provided above the peeling device 14. In the hot stamping method of one roll and two hot stampings, the hot stamping film with different entry directions will pass through the two sides of the first feed roller 26 and the second feed roller 36 at the same time. For example, the first feed roller 26 will pass through the hot stamping film unwound from the first unwinding position 24 on one side of the bottom of the first unwinding position 24, and will pass through the hot stamping film unwound from the first air roller 41 on one side of the bottom of the second unwinding position 25.

[0021] In practical operation, the hot stamping film unwinding device 2 unwinds the hot stamping film from the first unwinding position 24. The hot stamping film passes through multiple conveying rollers and the first feed roller 26. The hot stamping film then enters the bottom of the hot stamping pressure roller 13 and is hot stamped with the printed film. At this time, the metal foil on the hot stamping film is transferred to the designated pattern on the printed film. After hot stamping is completed, the printed film is separated from the hot stamping film at the peeling device 14. The separated printed film enters the subsequent process for winding. The separated hot stamping film moves upward, passes through the second feed roller 36, and reaches the position of the first air roller 41. The hot stamping film bypasses the first air roller 41 and is deflected, moving laterally in the support housing 11. Then the hot stamping film passes through the feed roller 43, then returns between the first air roller 41 and the second air roller 42, and then bypasses the second air roller 42 again. Roller 42 moves downwards and returns to the position of the first feed roller 26, ready for the second hot stamping. At this time, the hot stamping film has shifted from the first unwinding position 34 to the second unwinding position 35. The first hot stamping corresponds to the pattern on one side of the printed film, and the second hot stamping uses the remaining part of the hot stamping film to stamp the pattern on the other side of the printed film, achieving the effect of one roll for two hot stampings. After the hot stamping is separated by the peeling device 14, the hot stamping film enters the hot stamping film winding device 3 through the second feed roller 36 for winding. At this time, the hot stamping film is wound on the second winding position 35. Alternatively, it can be unwound simultaneously through the first unwinding position 24 and the second unwinding position 25. After hot stamping, it can be wound directly at the first winding position 34 and the second winding position 35 simultaneously without going through the hot stamping film flipping device 4, achieving the process of two rolls for two hot stampings.

[0022] This design is ingenious. The hot stamping film flipping device can adjust the position of the hot stamping film, enabling two hot stampings on one roll. This allows the hot stamping film to be printed on both sides of the pattern, effectively utilizing the hot stamping film and avoiding waste.

[0023] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
