Description

Technical Field

[0001] This utility model relates to the field of printing processing and production, specifically a hot and cold hot foil stamping integrated pressing device. Background Technology

[0002] In printing production, hot stamping utilizes the principle of heat transfer to transfer the aluminum layer from electroplated aluminum foil to the surface of the substrate, creating a unique metallic effect. Because the main material used in hot stamping is electroplated aluminum foil, it is also called electroplated aluminum foil stamping. Hot stamping is divided into cold hot stamping and hot hot stamping. The main differences lie in speed, cost, environmental friendliness, applicable materials, gloss, and process complexity. Cold hot stamping is faster, while hot hot stamping is slower. In printing hot stamping processes, different pressing devices need to be changed according to the requirements of cold and hot hot stamping. Therefore, changing between different pressing devices for cold and hot hot stamping incurs labor and time costs. Thus, researching and developing a pressing device that integrates cold and hot hot stamping has become a necessary technological requirement. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an integrated hot and cold foil stamping device to solve and improve the problem of changing different stamping devices according to the hot and cold foil stamping process requirements in general printing production. Therefore, changing different hot and cold foil stamping devices incurs labor and time costs. This utility model uses the hollow inner cavity of the integrated hot and cold foil stamping roller to introduce high-temperature oil to heat the roller, thus completing the hot foil stamping process. By discharging the high-temperature oil from the hollow inner cavity of the roller, the weight of the roller is reduced, increasing the rotation speed and achieving the cold foil stamping process. This avoids the need to change the foil stamping shaft, which increases the production cycle, and avoids the need to adjust the machine, which extends the production cycle. This effectively achieves the production objective of integrated hot and cold foil stamping.

[0004] This utility model is achieved through the following technical solution:

[0005] A hot and cold foil stamping integrated pressing device includes: a hot and cold foil stamping integrated base roller, a hot and cold foil stamping integrated plate roller, a rotary joint, a high-temperature oil inlet, a high-temperature oil outlet, a foil stamping film guide roller, a substrate guide roller, a substrate, and a foil stamping film.

[0006] The integrated hot and cold foil stamping base roller is cylindrical and mounted on the printing press via a drive shaft. It serves to receive the printing material and the foil stamping film. The integrated hot and cold foil stamping plate roller is also cylindrical, positioned directly below and tangentially to the base roller. The base roller, through its tangential compression action with the plate roller, adheres the foil stamping film to the printing material, completing the hot and cold foil stamping process. The plate roller is hollow, allowing high-temperature ink to enter the inner cavity, thus raising the outer surface temperature and completing the hot foil stamping process. The inner wall of the plate roller has an arched structure that decreases in height from the center to both sides, facilitating the smooth discharge of high-temperature ink and ensuring the integrated hot and cold foil stamping process is complete. The reduced weight and increased rotation speed of the printing roller enable cold foil stamping and hot foil printing. A cylindrical rotary joint is positioned at the end of the integrated hot and cold foil stamping roller and is connected to it, rotating coaxially with the roller. The high-temperature oil inlet is tubular and located on the rotary joint, communicating with the hollow inner cavity of the roller to facilitate the smooth flow of high-temperature oil from the inlet through the rotary joint into the roller. The high-temperature oil outlet is tubular and located at both ends of the roller, tangentially to it, communicating with the inner cavity to facilitate the smooth discharge of high-temperature oil from the roller.

[0007] Preferably, the hot stamping film guide roller is cylindrical and is positioned on both sides of the tangent point between the integrated hot and cold foil stamping base roller and the integrated hot and cold foil stamping plate roller, with a mirror distribution on both sides slightly above the center. The hot stamping film guide roller is mounted on the printing press via a drive shaft. The arrangement of the hot stamping film guide roller facilitates the guidance of the hot stamping film into the tangent point between the integrated hot and cold foil stamping base roller and the integrated hot and cold foil stamping plate roller for printing and pressing operations.

[0008] Preferably, the substrate guide roller is cylindrical and is positioned on both sides of the integrated hot and cold foil stamping base roller and the integrated hot and cold foil stamping plate roller at a slightly lower center position. The substrate guide rollers on both sides of the integrated hot and cold foil stamping base roller are located outside the foil stamping guide roller. The substrate guide roller is mounted on the printing press via a drive shaft. The placement of the substrate guide roller facilitates the guidance of the substrate into the tangent position of the integrated hot and cold foil stamping base roller and the integrated hot and cold foil stamping plate roller for printing and pressing operations, and facilitates the foil stamping on the surface of the substrate to complete the foil stamping printing task.

[0009] Preferably, the printing material is a sheet structure that needs to be processed, and the printing material extends from the printing material guide roller on one side to the point where the hot and cold foil stamping integrated bottom roller and the hot and cold foil stamping integrated plate roller are tangent to the printing material guide roller on the other side.

[0010] Preferably, the hot stamping film is a sheet structure based on the hot stamping process principle. The hot stamping film extends from the hot stamping film guide roller on one side to the tangent point between the integrated hot and cold stamping bottom roller and the integrated hot and cold stamping plate roller on the other side. The hot stamping film is placed on the printing material and adhered to the tangent point between the integrated hot and cold stamping bottom roller and the integrated hot and cold stamping plate roller.

[0011] Beneficial Effects: This solution provides an integrated hot and cold foil stamping device to solve and improve the problem of needing to change different stamping devices according to the hot and cold foil stamping process requirements in general printing production. Therefore, changing different hot and cold foil stamping devices requires labor and time costs. This utility model introduces high-temperature oil into the hollow cavity of the integrated hot and cold foil stamping roller to heat the roller and complete the hot foil stamping process. By discharging the high-temperature oil from the hollow cavity of the integrated hot and cold foil stamping roller, the weight of the roller is reduced and the rotation speed is increased to achieve the cold foil stamping process. This avoids the need to change the foil stamping shaft, which increases the production cycle, and avoids the need to adjust the machine, which increases the production cycle. This effectively achieves the production objective of integrated hot and cold foil stamping. Attached Figure Description

It serves to receive the printing material and the foil stamping film. The integrated hot and cold foil stamping plate roller 2 is also cylindrical and positioned directly below and tangentially to the bottom roller 1. The bottom roller 1, which receives the printing material and the foil stamping film, works in conjunction with the plate roller 2 to tangentially press and adhere the foil stamping film 9 to the printing material, completing the hot foil stamping task. The plate roller 2 is hollow, allowing high-temperature oil to enter the inner cavity, thus raising the outer surface of the plate roller 2 to a high temperature and completing the hot foil stamping task. The inner wall of the plate roller 2 has an arched structure that decreases in size from the center to both sides, facilitating the smooth discharge of high-temperature oil and reducing the weight of the plate roller 2. The rotation speed is reduced to increase, thereby achieving the cold foil stamping and hot foil printing task; the rotary joint 3 is cylindrical and set at the end of the integrated hot and cold foil stamping roller 2 and is connected to the integrated hot and cold foil stamping roller 2 through it, and the rotary joint 3 rotates coaxially with the integrated hot and cold foil stamping roller 2; the high temperature oil inlet 4 is a tubular structure and is set on the rotary joint 3, and the high temperature oil inlet 4 is connected to the hollow inner cavity of the integrated hot and cold foil stamping roller 2 through the rotary joint 3, so that the high temperature oil can smoothly enter the integrated hot and cold foil stamping roller 2 from the high temperature oil inlet 4 through the rotary joint 3; the high temperature oil outlet 5 is a tubular structure and is set at both ends of the integrated hot and cold foil stamping roller 2, and is tangential to the integrated hot and cold foil stamping roller 2, and is connected to the inner cavity of the integrated hot and cold foil stamping roller 2, so that the high temperature oil in the integrated hot and cold foil stamping roller 2 can be smoothly discharged.

[0019] Furthermore, the hot stamping film guide roller 6 is cylindrical and is positioned on both sides of the tangent point between the integrated hot and cold foil stamping base roller 1 and the integrated hot and cold foil stamping plate roller 2, with a mirror distribution on both sides. The hot stamping film guide roller 6 is mounted on the printing press via a drive shaft. The arrangement of the hot stamping film guide roller 6 facilitates the guidance of the hot stamping film 9 into the tangent point between the integrated hot and cold foil stamping base roller 1 and the integrated hot and cold foil stamping plate roller 2 for printing and pressing operations.

[0020] Furthermore, the substrate guide roller 7 is cylindrical and is positioned on both sides of the tangent point between the integrated hot and cold foil stamping base roller 1 and the integrated hot and cold foil stamping plate roller 2, in a mirror image arrangement. The substrate guide rollers 7 on both sides of the integrated hot and cold foil stamping base roller 1 are located outside the hot foil stamping film guide roller 6. The substrate guide rollers 7 are mounted on the printing press via a drive shaft. The placement of the substrate guide rollers 7 facilitates the guidance of the substrate 8 into the tangent point between the integrated hot and cold foil stamping base roller 1 and the integrated hot and cold foil stamping plate roller 2 for printing and pressing operations, and facilitates the hot foil stamping film 9 to be printed on the surface of the substrate 8 to complete the hot foil stamping task.

[0021] Furthermore, the printing material 8 is a sheet structure that needs to be processed. The printing material 8 extends from the printing material guide roller 7 on one side to the point where the hot and cold foil stamping integrated bottom roller 1 and the hot and cold foil stamping integrated plate roller 2 are tangent to the printing material guide roller 7 on the other side.

[0022] Furthermore, the hot stamping film 9 is a sheet structure based on the hot stamping process principle. The hot stamping film 9 extends from the hot stamping film guide roller 6 on one side to the point where the hot and cold stamping integrated bottom roller 1 and the hot and cold stamping integrated plate roller 2 are tangent to the hot stamping film guide roller 6 on the other side. The hot stamping film 9 is placed on the printing material 8 and is attached to the point where the hot and cold stamping integrated bottom roller 1 and the hot and cold stamping integrated plate roller 2 are tangent.

[0023] Working steps: The printing material is guided by the printing material guide roller to the tangential pressing area between the integrated hot and cold foil stamping bottom roller 1 and the integrated hot and cold foil stamping plate roller 2, and extends to the printing material guide roller on the other side. The foil stamping film is guided by the foil stamping film guide roller to the tangential pressing area between the integrated hot and cold foil stamping bottom roller 1 and the integrated hot and cold foil stamping plate roller 2, and extends to the printing material guide roller on the other side. High-temperature oil enters the integrated hot and cold foil stamping plate roller through the high-temperature oil inlet and a rotary joint, causing the temperature of the integrated hot and cold foil stamping plate roller to rise and realize the hot foil stamping process. The high-temperature oil is discharged from the high-temperature oil outlet on the side of the end of the integrated hot and cold foil stamping plate roller. The weight of the integrated hot and cold foil stamping plate roller decreases and the rotation speed increases, thereby realizing the cold foil stamping process.
