Description

Technical Field

[0001] This invention belongs to the field of hot stamping technology, and specifically relates to a hot stamping device and process with a steering function. Background Technology

[0002] Hot stamping is a surface decoration technique that uses heat and pressure to transfer the metal or pigment layer on a hot stamping film to the surface of a substrate. It is widely used in packaging printing, label manufacturing, textiles, and handicrafts. The core equipment for this process is a hot stamping machine, which typically includes an unwinding mechanism, hot stamping components (including a heating plate and a pressure mechanism), and a rewinding mechanism. Hot stamping film generally has a multi-layered structure, with a release layer, a color layer, or a metal layer sequentially coated on a base film. During hot stamping, the hot stamping components apply heat and pressure to specific areas, causing the color or metal layer in that area to separate from the base film and transfer to the substrate.

[0003] In existing hot stamping machines, the hot stamping film is continuously or incrementally fed through the hot stamping assembly along its length. After each hot stamping operation (forming a hot stamping pattern), the film moves forward a certain distance to allow unused segments to enter the hot stamping station for the next operation. However, since hot stamping patterns typically do not continuously cover the entire width of the film, there must be a certain gap between adjacent patterns in the film's travel direction (longitudinal). Although the film material in this gap area is not involved in the transfer, in existing technologies, it is either rolled up or discarded along with the used portion of the roll and cannot be reused. This essentially treats the entire roll of hot stamping film as a "disposable consumable," resulting in a significant waste of large areas not covered by the pattern, leading to low material utilization.

[0004] With the expansion of production scale and the increasing demands for environmental protection, this problem of material waste has become increasingly prominent, significantly driving up production costs. This is especially true when using expensive special hot stamping films (such as holographic films and laser films), where the cost pressure is even greater. Therefore, there has been a long-standing and continuous technological need in this field: to improve the design of hot stamping machines to utilize hot stamping film materials more efficiently, reduce or avoid material waste in the gaps between patterns, and thus effectively reduce material costs in the production process while ensuring the quality of hot stamping.

[0005] To address this, the industry has made some attempts, such as optimizing the layout to reduce the spacing between patterns, but this is limited by the design of the patterns themselves and the safe hot stamping distance, resulting in limited cost savings; or trying to recycle waste film for material reprocessing, but the process is complex and not economically viable. Currently, there is a lack of a simple, efficient, and reliable solution that can be directly implemented on a hot stamping machine to fundamentally improve the effective utilization rate of a single roll of hot stamping film. Summary of the Invention

[0006] To address the aforementioned problems, the primary objective of this invention is to provide a hot stamping apparatus and process with a steering function, which can significantly reduce the length of hot stamping film consumed per unit product.

[0007] The secondary objective of this invention is to provide a hot stamping apparatus and process with a steering function, which significantly reduces the material cost of hot stamping film in production, especially when using expensive special films. This reduces material waste and helps to achieve a more environmentally friendly and sustainable production method.

[0008] To achieve the above objectives, the technical solution of the present invention is as follows:

[0009] This invention provides a hot stamping device with a steering function, characterized in that it comprises:

[0010] Hot stamping equipment is used to hot stamp the foil.

[0011] The hot stamping film unwinding mechanism is used to feed the hot stamping film into the hot stamping machine for one hot stamping operation.

[0012] The turning mechanism is used to turn the hot stamping film after the first hot stamping and let it re-enter the hot stamping mechanism for a second hot stamping.

[0013] The hot stamping film winding mechanism is used to wind up the hot stamping film after it has been hot stamped twice by the hot stamping mechanism.

[0014] In this invention, by setting a turning mechanism, the hot stamping film that has undergone one hot stamping can be turned and then enter the hot stamping mechanism for a second hot stamping process, realizing the reuse of the hot stamping film. This avoids the material waste caused by directly rolling up and scrapping the hot stamping film after one hot stamping, greatly reducing the length of hot stamping film consumed per unit product, significantly reducing the material cost of hot stamping film in production, and helping to achieve a more environmentally friendly and sustainable production method.

[0015] Furthermore, the device also includes a feeding mechanism for feeding the material to be hot-stamped into the hot-stamping mechanism.

[0016] Furthermore, the device also includes a feeding mechanism for receiving and feeding the hot-stamped material.

[0017] Furthermore, the steering mechanism includes a first steering assembly, a second steering assembly, and a bogie, with the first and second steering assemblies connected to the bogie. By setting the first and second steering assemblies, the hot stamping film can be flipped through two turns. When the hot stamping film enters the hot stamping assembly for the second time, the working end is kept facing the material to be hot stamped.

[0018] Furthermore, the first steering assembly and the second steering assembly are slidably connected to the bogie. This slidable connection allows adjustment of the positions of the first and second steering assemblies on the bogie, enabling the hot stamping film to be positioned to suit different material processing locations, thus accommodating hot stamping processes on various materials.

[0019] Furthermore, the first steering assembly includes a first mounting plate, a first steering rod, and a first slider. The first steering rod is rotatably connected to the first mounting plate, and the first mounting plate is slidably connected to the bogie via the first slider. Preferably, both ends of the first steering rod are rotatably mounted on one side of the first mounting plate via bearings, and the first slider is fixed on the other side of the first mounting plate. A pair of guide rods are provided on the bogie to cooperate with the first slider.

[0020] Furthermore, the first steering rod forms a 45-degree angle with the horizontal direction. Strictly speaking, the first steering rod is at a 45-degree angle to the surface of the material to be hot-stamped. After the two steering components turn, they will form a 90-degree turn, which is just right to flip the material over, and the direction and angle of entry into the hot-stamping mechanism are also just right.

[0021] Furthermore, the second steering assembly includes a second mounting plate, a second steering rod, and a second slider. The second steering rod is rotatably connected to the second mounting plate, and the second mounting plate is slidably connected to the bogie via the second slider. Preferably, both ends of the second steering rod are rotatably mounted on one side of the second mounting plate via bearings, and the second slider is fixed to the other side of the second mounting plate. A pair of guide rods are provided on the bogie to cooperate with the second slider.

[0022] Furthermore, the second steering rod forms a 45-degree angle with the horizontal direction. Strictly speaking, the second steering rod is at a 45-degree angle to the surface of the material to be hot-stamped. After the two steering components turn, they will form a 90-degree turn, which is just right to flip the material over, and the direction and angle of entry into the hot-stamping mechanism are also just right.

[0023] Furthermore, the device also includes an adjustment component for adjusting the position of the hot stamping film entering the hot stamping mechanism for secondary hot stamping. This adjustment component is located between the first steering component and the second steering component. The main function of the adjustment component is to flexibly adjust the entry position of the hot stamping film entering the hot stamping mechanism for the second time. This not only adjusts the hot stamping position but also prevents the position of the second hot stamping from overlapping with the position of the first hot stamping, thus avoiding processing defects. This adjustment can also be referred to as hot stamping film stroke adjustment.

[0024] Furthermore, the adjustment assembly includes an adjustment mounting plate and an adjustment rod, the adjustment rod being rotatably connected to the adjustment mounting plate, and the adjustment mounting plate being movably connected to the bogie. Preferably, the adjustment mounting plate is slidably connected to the guide rod of the bogie via an adjustment slider.

[0025] Furthermore, the adjustment assembly also includes a first connecting assembly and a second connecting assembly mounted on the bogie, with a gap between them. When the adjustment mounting plate moves on the bogie, it approaches or moves away from this gap. In specific operation, the hot stamping film unwinding mechanism unwinds the hot stamping film. The film first enters the hot stamping mechanism for a single hot stamping process, then exits and undergoes a first turn via the first turning assembly. After turning, it wraps around the first connecting assembly and enters the gap. It then wraps around one end of the adjusting rod and extends out from the other end, exiting the gap again. It then wraps around the second connecting assembly, exits from the second connecting assembly, and enters the second turning assembly for a second turn. Next, it enters the hot stamping mechanism for a second hot stamping process, and finally is wound onto the hot stamping film winding mechanism.

[0026] Furthermore, the first connecting component includes a first connecting roller, the second connecting component includes a second connecting roller, and the gap is formed between the first connecting roller and the second connecting roller. In the processing path direction, the first connecting roller is located between the first steering component and the adjusting component, and the second connecting roller is located between the adjusting component and the second steering component.

[0027] Furthermore, the device also includes a frame on which at least one of the hot stamping mechanism, hot stamping film unwinding mechanism, turning mechanism, and hot stamping film rewinding mechanism is mounted. The main purpose of the frame is to provide mounting positions and space for the aforementioned mechanisms.

[0028] Furthermore, the hot stamping mechanism includes a varnish spraying assembly, a hot stamping roller, and a UV curing assembly arranged sequentially. Preferably, the hot stamping roller, varnish spraying assembly, and UV curing assembly are all mounted on a frame, and the UV curing assembly is a high-power UV lamp. In specific processing, the material to be hot stamped is first sprayed with varnish by the varnish spraying assembly. Then, the varnished material is adhered to the hot stamping film on the hot stamping roller, and then irradiated by the UV curing assembly. After the varnish cures, it adheres to the portion of the hot stamping film that was adhered to it, thereby achieving hot stamping of the material.

[0029] Furthermore, the hot stamping mechanism also includes a UV pre-curing component, located between the varnish spraying component and the hot stamping roller, for pre-curing the varnish. The UV pre-curing component is a UV lamp, mainly used to pre-cur the varnish sprayed on the material to prevent deformation of the varnish pattern and help reduce the defect rate.

[0030] Furthermore, the hot stamping roller is equipped with a cooling channel. During operation, a cooling pipe is connected to the cooling channel, which can circulate coolant to cool the surface of the roller, preventing the material from being damaged due to overheating during operation.

[0031] Furthermore, the varnish spraying assembly includes a housing, a nozzle, and a varnish tank for storing varnish. The varnish tank is mounted on the housing, and the nozzle is connected to the varnish tank to spray the varnish from the tank.

[0032] Furthermore, the housing is slidably connected to the frame, allowing the varnish spraying assembly to move between a working position and a non-working position. The slidable connection of the housing to the frame enables switching between working and idle states for the varnish spraying assembly. When the varnish spraying assembly is to be used, it is slidably positioned above the material to be hot-stamped; when it is not needed or requires maintenance, it is slid away from the material.

[0033] Furthermore, the hot stamping film unwinding mechanism includes an unwinding roller and an unwinding motor, wherein the unwinding motor is connected to the unwinding roller to drive the unwinding roller to rotate.

[0034] Furthermore, the hot stamping film winding mechanism includes a winding roller and a winding motor, wherein the unwinding motor is connected to the unwinding roller to drive the unwinding roller to rotate.

[0035] The present invention also provides a hot stamping process based on the above-mentioned device, characterized by comprising the following steps: First hot stamping: the hot stamping film enters the hot stamping mechanism for first hot stamping;

[0036] Secondary hot stamping: The hot stamping film that has undergone the first hot stamping is turned by the turning mechanism and then enters the same hot stamping mechanism for secondary hot stamping.

[0037] Furthermore, the process includes unwinding the hot stamping film before the first hot stamping operation. The hot stamping film is unwound by the hot stamping film unwinding mechanism so that it can enter the hot stamping mechanism for the first hot stamping operation.

[0038] Furthermore, the process also includes hot stamping film winding after the second hot stamping, with the hot stamping film winding mechanism winding the hot stamping film to recycle the hot stamping film after the second hot stamping.

[0039] Furthermore, the process includes feeding the material to be hot-stamped: the material to be hot-stamped is fed into the hot-stamping mechanism and bonded with the hot-stamping film through the feeding mechanism.

[0040] Furthermore, the process includes cutting the material to be hot-stamped: the hot-stamped material is cut using a cutting mechanism.

[0041] Compared with the prior art, the beneficial effects of the present invention are: by setting a turning mechanism, the hot stamping film that has undergone one hot stamping can be turned and then enter the hot stamping mechanism for a second hot stamping process, realizing the reuse of the hot stamping film, avoiding the material waste caused by directly rolling up and scrapping the hot stamping film after one hot stamping, greatly reducing the length of hot stamping film consumed per unit product, significantly reducing the material cost of hot stamping film in production, and helping to achieve a more environmentally friendly and sustainable production method.

[0062] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0063] To achieve the above objectives, the technical solution of the present invention is as follows:

[0064] See Figures 1-11 As shown, the present invention provides a hot stamping device with a steering function, comprising:

[0065] Hot stamping unit 1 is used for hot stamping the hot stamping film;

[0066] Hot stamping film unwinding mechanism 2 is used to feed hot stamping film into hot stamping mechanism 1 for one hot stamping operation;

[0067] The turning mechanism 3 is used to turn the hot stamping film after the first hot stamping and let it re-enter the hot stamping mechanism 1 for a second hot stamping.

[0068] The hot stamping film winding mechanism 4 is used to wind up the hot stamping film after it has been hot stamped twice by the hot stamping mechanism 1.

[0069] In this invention, by setting a turning mechanism 3, the hot stamping film that has undergone one hot stamping can be turned and then enter the hot stamping mechanism 1 for a second hot stamping process, realizing the reuse of the hot stamping film. This avoids the material waste caused by directly rolling up and scrapping the hot stamping film after one hot stamping, greatly reducing the length of hot stamping film consumed per unit product, significantly reducing the material cost of hot stamping film in production, and helping to achieve a more environmentally friendly and sustainable production method.

[0070] In this embodiment, the device further includes a feeding mechanism 5, which is used to feed the material to be hot-stamped into the hot-stamping mechanism 1.

[0071] In this embodiment, the device further includes a feeding mechanism 6, which is used to receive the hot-stamped material and feed it.

[0072] In this embodiment, the steering mechanism 3 includes a first steering component 31, a second steering component 32, and a bogie 33. The first steering component 31 and the second steering component 32 are connected to the bogie 33. By setting the first steering component 31 and the second steering component 32, the hot stamping film can be flipped after two turns. When the hot stamping film enters the hot stamping component 1 for the second time, the working end is kept facing the material to be hot stamped.

[0073] In this embodiment, the first steering assembly 31 and the second steering assembly 32 are slidably connected to the bogie 33. The slidable connection of the first steering assembly 31 and the second steering assembly 32 to the bogie 33 allows for adjustment of their positions on the bogie 33, enabling the hot stamping film to be adapted to different material processing positions, thereby accommodating hot stamping processing of different materials.

[0074] In this embodiment, the first steering assembly 31 includes a first mounting plate 311, a first steering rod 312, and a first slider 313. The first steering rod 312 is rotatably connected to the first mounting plate 311, and the first mounting plate 311 is slidably connected to the bogie 33 via the first slider 313. Preferably, both ends of the first steering rod 312 are rotatably mounted on one side of the first mounting plate 311 via bearings, and the first slider 313 is fixed on the other side of the first mounting plate 311. The bogie 33 is provided with a pair of guide rods 331 for cooperating with the first slider 313.

[0075] In this embodiment, the first steering rod 312 forms a 45-degree angle with the horizontal direction. Strictly speaking, the first steering rod forms a 45-degree angle with the surface of the material to be hot-stamped. After the two steering components turn, they will form a 90-degree turn, which is just enough to flip the material over. At the same time, the direction and angle of entering the hot-stamping mechanism 1 are also just right.

[0076] In this embodiment, the second steering assembly 32 includes a second mounting plate 321, a second steering rod 322, and a second slider 323. The second steering rod 322 is rotatably connected to the second mounting plate 321, and the second mounting plate 321 is slidably connected to the bogie 33 via the second slider 323. Preferably, both ends of the second steering rod 322 are rotatably mounted on one side of the second mounting plate 321 via bearings, and the second slider 323 is fixed on the other side of the second mounting plate 321. The bogie 33 is provided with a pair of guide rods 331 for cooperating with the second slider 323.

[0077] In this embodiment, the second steering rod 322 forms a 45-degree angle with the horizontal direction. Strictly speaking, the second steering rod 322 forms a 45-degree angle with the surface of the material to be hot-stamped. After the two steering components turn, they will form a 90-degree turn, which is just enough to flip the material over, and the direction and angle of entry into the hot-stamping mechanism 1 are also just right.

[0078] In this embodiment, the device further includes an adjustment component 7 for adjusting the position of the hot stamping film entering the hot stamping mechanism 1 for secondary hot stamping. The adjustment component 7 is located between the first steering component 31 and the second steering component 32. The main function of the adjustment component 7 is to flexibly adjust the entry position of the hot stamping film entering the hot stamping mechanism 1 for the second time. This not only achieves the function of adjusting the hot stamping position but also prevents the position of the second hot stamping from overlapping with the position of the first hot stamping, thus avoiding processing defects. The above adjustment can also be referred to as the stroke adjustment of the hot stamping film.

[0079] In this embodiment, the adjustment assembly 7 includes an adjustment mounting plate 71 and an adjustment rod 72. The adjustment rod 72 is rotatably connected to the adjustment mounting plate 71, and the adjustment mounting plate 71 is movably connected to the bogie 33. Preferably, the adjustment mounting plate 71 is slidably connected to the guide rod 331 of the bogie 33 via an adjustment slider 73.

[0080] In this embodiment, the adjusting assembly 7 further includes a first connecting assembly 74 and a second connecting assembly 75 mounted on the bogie 33. A gap 76 is formed between the first connecting assembly 74 and the second connecting assembly 75. When the adjusting mounting plate 71 moves on the bogie 33, it moves closer to or further away from the gap 76. In specific operation, the hot stamping film unwinding mechanism 2 unwinds the hot stamping film. The hot stamping film first enters the hot stamping mechanism 1 for a first hot stamping process. After exiting, it undergoes a first turn via the first turning assembly 31. After the turn, it wraps around the first connecting assembly 74 and enters the gap 76. Then, it wraps around the adjusting rod 72 from one end and extends out from the other end of the adjusting rod 72. It then exits from the gap 76 and wraps around the second connecting assembly 75. After exiting the second connecting assembly 75, it enters the second turning assembly 32 for a second turn. Then, it enters the hot stamping mechanism 1 for a second hot stamping process and is finally wound onto the hot stamping film winding mechanism 4.

Preferably, the hot stamping roller 12, the varnish spraying assembly 11, and the UV curing assembly 13 are all mounted on the frame 8, and the UV curing assembly 13 is a high-power UV lamp. In specific processing, the material to be hot stamped is first sprayed with varnish by the varnish spraying assembly 11, and then the varnished material is bonded to the hot stamping film on the hot stamping roller 12. Then, it is irradiated by the UV curing assembly 13. After the varnish cures, it will adhere the part of the hot stamping film that is bonded to it, thereby achieving hot stamping of the material.

[0084] In this embodiment, the hot stamping mechanism 1 further includes a UV pre-curing component 14, which is located between the varnish spraying component 11 and the hot stamping roller 12, and is used to pre-cur the varnish. The UV pre-curing component 14 is a UV lamp, which is mainly used to pre-cur the varnish sprayed on the material to prevent the varnish pattern from deforming, which helps to reduce the defect rate.

[0085] In this embodiment, a cooling channel is provided inside the hot stamping roller 12. During operation, a cooling pipe 121 is connected to the cooling channel, which can circulate coolant to cool the surface of the cooling roller 12, preventing the material from being damaged due to overheating during operation.

The slidable connection of the housing 111 to the frame 8 enables switching between a working state and a resting state for the varnish spraying assembly 11. When the varnish spraying assembly 11 is to be used, it is slidably positioned above the material to be hot-stamped. When the varnish spraying assembly 11 is not needed or requires maintenance, it is slid to a side away from the material.
