Description

Technical Field

[0001] This invention relates to the field of tobacco production, specifically to a three-dimensional hot stamping device, a hot stamping system, and a three-dimensional hot stamping method for cigarette labels. Background Technology

[0002] Hot stamping is a decorative process in cigarette label manufacturing. It involves fixing the color layer from a hot stamping foil onto the cigarette label material. The hot stamping foil consists of a base film, a release layer, a color layer, and an adhesive layer. The base film, such as polyester film, provides support; the release layer separates the hot-stamped color layer from the base film; the color layer determines the final color effect; and the adhesive layer adheres the color layer to the cigarette label material.

[0003] The inventors discovered that existing technologies suffer from at least the following problems: In the hot stamping process, the stamping pressure directly affects the stamping effect; excessively high or low pressure will result in poor stamping quality. To ensure the stamping effect, the stamping pressure needs to be repeatedly adjusted during the cigarette label stamping process. Furthermore, there may be areas where the stamping pressure is not up to standard, so it is also necessary to determine the location on the cigarette label material where the pressure needs to be adjusted. The cigarette label occupies a small proportion of the cigarette box area, and the area requiring pressure adjustment is even smaller, making it very time-consuming to locate and adjust the pressure on the cigarette label material. These factors lead to low production efficiency in the hot stamping process and a low final product qualification rate. Summary of the Invention

[0004] This invention proposes a three-dimensional hot stamping device, a hot stamping system, and a three-dimensional hot stamping method for cigarette labels, in order to improve the production efficiency and pass rate of the hot stamping process for cigarette labels.

[0005] This invention provides a three-dimensional hot stamping device for cigarette labels, comprising:

[0006] Positioning plate, including the cut-out section;

[0007] A buffer element, the outline shape of which matches the shape of the hollowed-out portion, and the buffer element is located in the hollowed-out portion;

[0008] A tracing paper material layer includes a graphic section and a pull-out section, wherein the graphic section and the pull-out section are fixedly connected or integral; the graphic section is located within the cutout section, and the pull-out section is located outside the cutout section; and

[0009] The resin material layer matches the overall shape of the positioning plate and is fixedly connected to the positioning plate.

[0010] In some embodiments, the cutout portion is located at the edge of the positioning plate.

[0011] In some embodiments, the cutout portion is constructed as a trapezoid or a triangle.

[0012] In some embodiments, the graphic section is printed with graphic markings to be printed.

[0013] In some embodiments, the buffer is made of copper sheet.

[0014] In some embodiments, the resin material layer is configured to be transparent.

[0015] This invention also provides a hot stamping system, comprising:

[0016] Hot stamping machines, including 3D hot stamping dies; and

[0017] The cigarette label three-dimensional hot stamping device provided by any technical solution of the present invention is in cooperation with the three-dimensional hot stamping base plate.

[0018] This invention also provides a method for three-dimensional hot stamping of cigarette labels, comprising the following steps:

[0019] Cover the surface of each cigarette box to be hot-stamped with a positioning plate of the three-dimensional hot-stamping device for cigarette labels provided by any of the technical solutions of this invention.

[0020] The buffer and the sulfuric acid paper material layer are placed in the hollow part of the positioning plate;

[0021] The resin material layer is covered on the surface of the sulfuric acid paper material layer; wherein the graphic markings printed on the graphic portion of the sulfuric acid paper material layer are the same in shape and size as the cigarette label to be hot-stamped;

[0022] A hot stamping machine is used to apply hot stamping pressure to the cigarette label three-dimensional hot stamping device to hot stamp the cigarette label on the surface of the cigarette box.

[0023] In some embodiments, the cigarette label three-dimensional hot stamping method further includes the following steps:

[0024] Check whether the cigarette label hot-stamped on the surface of the cigarette box meets the requirements;

[0025] If the cigarette label formed by hot stamping on the surface of the cigarette box does not meet the requirements, the area where the cigarette label formed by hot stamping on the surface of the cigarette box does not meet the requirements is identified, and this area is the first area;

[0026] Pull out the pull-out section of the sulfuric acid paper material layer;

[0027] Locate the area in the graphic portion of the sulfuric acid paper material layer that corresponds to the area where the cigarette label does not meet the requirements; this area is the second area.

[0028] A pushing force is applied to the pull-out portion of the sulfuric acid paper material layer, pushing the sulfuric acid paper material layer back into the hollow portion of the positioning plate;

[0029] Adjust the pressure of the hot stamping machine corresponding to the second region of the graphic portion of the tracing paper material layer;

[0030] The hot stamping machine is reused to apply hot stamping pressure to the cigarette label three-dimensional hot stamping device to hot stamp the cigarette label on the surface of the cigarette box.

[0031] In some embodiments, a plurality of the aforementioned three-dimensional hot stamping devices are covered on the surface of each cigarette box to be hot stamped with a cigarette label, and each of the three-dimensional hot stamping devices is arranged at intervals.

During the hot stamping process, it can quickly find the position where the hot stamping pressure is not up to standard and can quickly replenish the pressure in the position where the 3D hot stamping pressure is too low. The device uses the hollow part for positioning and fixing, which can directly position the position where the pressure needs to be adjusted, thereby reducing the time for repositioning the bottom mold and the hot stamping plate after replenishing the pressure, reducing the time for repeated machine stops to adjust the pressure, reducing the hot stamping waste caused by machine adjustment, and improving the hot stamping production efficiency and yield.

[0033] Furthermore, the 3D hot stamping device for cigarette labels provided by the above technical solution has low requirements for the skill level of the operator. Regardless of the operator's skill level, they can quickly identify whether the hot stamping pressure meets the requirements and the specific parts where the hot stamping pressure does not meet the requirements, which can ultimately improve the quality consistency of the hot stamping finished products.

[0049] Explanation of the nouns or terms used in this article.

[0050] Hot stamping is a special printing process that does not use ink. Hot stamping refers to the process of hot stamping electroplated aluminum foil onto the surface of a substrate under certain temperature and pressure. A hot stamping machine is the equipment used to complete the hot stamping process.

[0051] Figure 1 This is an exploded structural diagram of the cigarette label three-dimensional hot stamping device provided in an embodiment of the present invention.

[0052] See Figure 1 This invention provides a three-dimensional hot stamping device for cigarette labels, comprising a positioning plate 1, a buffer member 2, a tracing paper material layer 3, and a resin material layer 4. The positioning plate 1 includes a cutout portion 11; the outline shape of the buffer member 2 matches the shape of the cutout portion 11, and the buffer member 2 is located within the cutout portion 11. The tracing paper material layer 3 includes a graphic portion 31 and a pull-out portion 32, which are fixedly connected or integral; the graphic portion 31 is located within the cutout portion 11, and the pull-out portion 32 is located outside the cutout portion 11. The resin material layer 4 matches the overall shape of the positioning plate 1 and is fixedly connected to the positioning plate 1. The resin material layer 4 is constructed to be transparent for easy observation.

[0053] The positioning plate 1 can be made of cardboard, etc. The material of the positioning plate 1 is mainly related to the toughness and stiffness of the cardboard, and also matches the adaptability of hot stamping. Therefore, the positioning plate 1 can be made of cardboard or a base paper with hot stamping capability. The positioning plate 1 is provided with a cutout portion 11, which forms a positioning and fit with the buffer component 2 and the tracing paper material layer 3. The buffer component 2 and the tracing paper material layer 3 can be accurately inserted into the cutout portion 11. The cutout portion 11 can provide a precise positioning reference for the mating parts, ensuring accurate hot stamping in the subsequent process. In addition, the cutout portion 11 makes the assembly process of the buffer component 2 and the tracing paper material layer 3 more intuitive and convenient. Operators can quickly install the parts in the correct position by observing the fit between the cutout portion 11 and the positioning components, improving installation efficiency.

[0054] The resin material layer 4 and the positioning plate 1 are fixedly connected. Specifically, they can be glued and fixed at the rest where they are in contact with each other. The structure formed by the resin material layer 4 and the positioning plate 1 protects the buffer 2 and the tracing paper material layer 3. The structure formed by the resin material layer 4 and the positioning plate 1 is grooved at the corresponding cutout 11, which makes it easier for the buffer 2 and the tracing paper material layer 3 to be embedded in the cutout 11, and the fixed position does not shift or deform.

[0055] The tracing paper material layer 3 includes a graphic section 31 and a pull-out section 32. Utilizing the heat-pressing area graphics of the graphic section 31, the area requiring pressure adjustment can be quickly and directly located based on the heat-pressing effect, reducing search and machine setup time, lowering the scrap rate, and improving production efficiency. Furthermore, the size design of the tracing paper material layer 3 and the buffer 2 directly corresponds to and is embedded into the cutout section 11, forming a pull-out structure. This facilitates the removal of the tracing paper material layer 3 during pressure adjustment, saving time and preventing damage. In addition, the tracing paper material layer 3 must be absorbent, absorbing moisture or water generated during the heat-pressing process without deformation or damage. Moreover, the tracing paper material layer 3 can be repeatedly pulled out, improving operational convenience and repeatability.

[0056] See also Figure 1 In some embodiments, the cutout 11 is located at the bottom edge, facilitating alignment and calibration. The edge position is easier to see and touch, allowing operators to visually align the components to be installed with the cutout 11 during assembly of the buffer 2 and the tracing paper layer 3, significantly improving assembly efficiency. When it is necessary to remove the buffer 2 and the tracing paper layer 3, they can be easily pulled out from the cutout 11 without being obstructed by other components, providing convenient operation and ample operating space.

[0057] In some embodiments, the cutout portion 11 is configured as trapezoidal or triangular. The edges of the trapezoidal or triangular cutout portion 11 guide the installation of the buffer member 2 and the tracing paper material layer 3, preventing installation errors and ensuring the correct installation of the buffer member 2 and the tracing paper material layer 3.

[0058] See also Figure 1 In some embodiments, the graphic section 31 is printed with graphic markings to be printed. The graphic markings are the same shape and size as the cigarette label to be printed. During the hot stamping process, the positioning plate 1, the buffer 2, the tracing paper material layer 3, and the resin material layer 4 are stacked together, and the position corresponding to the graphic markings is the position on the cigarette box where the cigarette label needs to be formed. Taking the "Seven Wolves" cigarette label as an example, if the markings on the wolf's head are unclear or the color is incorrect after hot stamping, the graphic section 31 can accurately identify the position corresponding to the wolf's head. When hot stamping again, the pressure corresponding to the wolf's head can be increased or decreased as needed to obtain a three-dimensional cigarette label that meets the requirements. Furthermore, it is not necessary to adjust the hot stamping pressure of other parts of the wolf. It can be seen that the technical solution of this embodiment of the invention can not only quickly find out whether the hot stamping pressure meets the requirements, but also quickly find the position that does not meet the requirements, and can quickly adjust the pressure of the corresponding position of the hot stamping machine so that the final three-dimensional cigarette label meets the requirements.

[0059] In some embodiments, the buffer 2 is made of copper sheet. Copper sheet is tough and can cushion the pressing during the hot stamping process, preventing the resin material layer 4 from cracking during hot stamping, and protecting and facilitating the removal and insertion of the tracing paper material layer 3.

[0060] This invention also provides a hot stamping system, including a hot stamping machine and a 3D hot stamping device for cigarette labels provided by any of the technical solutions of this invention. The hot stamping machine includes a 3D hot stamping base plate; the 3D hot stamping device for cigarette labels cooperates with the 3D hot stamping base plate.

[0061] Each hot stamping machine is equipped with multiple independent 3D hot stamping devices for cigarette labels. If the hot stamping pressure is insufficient at one of these devices, only the buffer element 2 and the tracing paper layer 3 of that device can be removed without affecting the position or operation of other devices. This significantly improves the ease of adjustment.

[0062] The hot stamping system provided by the above technical solution features a three-dimensional hot stamping device for cigarette labels. This solves the problem of repeated alignment with the hot stamping plate caused by the complete lifting of the resin tracing paper layer 3 in existing pressure compensation methods, reducing hot stamping waste due to misalignment. Furthermore, the hot stamping system adopts an embedded structure, which, while achieving overall registration stability, utilizes a pull-out design to extend the buffer 2 and tracing paper layer 3 for pressure compensation at corresponding positions. This reduces the time spent adjusting registration and finding the pressure position to be adjusted. Moreover, the overall embedded design, based on material selection, can also minimize the need for remaking the positioning device due to water absorption, decay, or deformation of the material, thus improving the device's utilization rate. Therefore, this hot stamping system can also be applied to other locations and scenarios. Practice has proven that this hot stamping system, with its reasonable structure, low manufacturing cost, and simple installation and operation, performs well in hot stamping processes.

[0063] Figure 4 This is a schematic diagram of a three-dimensional hot stamping method for cigarette labels provided in an embodiment of the present invention. See also... Figure 4 This invention also provides a method for three-dimensional hot stamping of cigarette labels, comprising the following steps:

[0064] Step S100: Cover the surface of each cigarette box to be hot-stamped with a positioning plate 1 of the cigarette label three-dimensional hot stamping device provided by any of the technical solutions of the present invention.

[0065] Step S200: Place the buffer 2 and the sulfuric acid paper material layer 3 in the hollow part 11 of the positioning plate 1.

[0066] In step S300, a resin material layer 4 is covered on the surface of the tracing paper material layer 3; wherein the graphic markings printed on the graphic portion 31 of the tracing paper material layer 3 are the same in shape and size as the cigarette label to be hot-stamped.

[0067] In step S400, a hot stamping machine is used to apply hot stamping pressure to the cigarette label three-dimensional hot stamping device to hot stamp the cigarette label on the surface of the cigarette box.

[0068] In some embodiments, the cigarette label three-dimensional hot stamping method further includes the following steps:

[0069] Step S500: Check whether the cigarette label formed by hot stamping on the surface of the cigarette box meets the requirements.

[0070] In step S600, if the cigarette label formed by hot stamping on the surface of the cigarette box does not meet the requirements, the area where the cigarette label formed by hot stamping on the surface of the cigarette box does not meet the requirements is identified, and this area is the first area.

[0071] Step S700: Pull out the pull-out part 32 of the sulfuric acid paper material layer 3.

[0072] Step S800: Locate the area in the graphic section 31 of the sulfuric acid paper material layer 3 that does not meet the requirements for the cigarette label. This area is the second area.

[0073] In step S900, a pushing force is applied to the pull-out portion 32 of the sulfuric acid paper material layer 3 to push the sulfuric acid paper material layer 3 back into the cutout portion 11 of the positioning plate 1.

[0074] Step S1000: Adjust the pressure of the hot stamping machine corresponding to the second area of ​​the graphic section 31 of the tracing paper material layer 3.

[0075] Step S1100: Apply hot stamping pressure to the cigarette label 3D hot stamping device again using the hot stamping machine to hot stamp the cigarette label on the surface of the cigarette box.

[0076] In some embodiments, multiple three-dimensional hot stamping devices for cigarette labels are covered on the surface of each cigarette box to be hot stamped, with each three-dimensional hot stamping device arranged at intervals.

[0077] The above-mentioned technical solution for 3D hot stamping of cigarette labels allows for embedded design of the 3D hot stamping device when the work scenario requires repeated adjustments and material extraction. Furthermore, during the hot stamping process, it can quickly locate positions where the hot stamping pressure is insufficient, eliminating the need for repeated adjustments and calibrations. This reduces adjustment time, minimizes downtime, and ensures a high success rate and production efficiency. In addition, it solves the problems of machine wear and tear and device instability caused by repeated adjustments and material extraction, enabling rapid and efficient locking of the position to be adjusted and reducing the time spent repeatedly calibrating the position of the hot stamping plate and the resin tracing paper layer 3 due to pressure adjustments.
