Description

Technical Field

[0001] The invention relates to the field of tobacco production, and in particular to a cigarette label three-dimensional hot stamping device, a hot stamping system and a cigarette label three-dimensional hot stamping method. Background Art

[0002] The hot stamping process of cigarette label products is a decorative process in the production process of cigarette labels. The hot stamping process is to fix the color layer on the hot stamping foil on the cigarette label material. The hot stamping foil includes a base film, a release layer, a color layer and a glue layer. The base film is, for example, a polyester film, which provides support; the release layer separates the color layer from the base film after hot stamping; the color layer determines the color effect after hot stamping; and the glue layer is used to stick the color layer to the cigarette label material.

[0003] The inventors have discovered that there are at least the following problems in the prior art: In the hot stamping process, the hot stamping pressure directly affects the hot stamping effect. Too high or too low a hot stamping pressure will lead to a poor hot stamping effect. In order to ensure the hot stamping effect, the hot stamping pressure needs to be adjusted repeatedly during the hot stamping of the cigarette label. In addition, there may be a situation where the hot stamping pressure in some areas does not meet the requirements, so it is also necessary to determine the position of the pressure to be adjusted on the cigarette label material. The cigarette label occupies a small proportion of the cigarette box area, and the area where the pressure needs to be adjusted is even smaller. It is very time-consuming to find and adjust the position of the pressure to be adjusted on the cigarette label material. These factors lead to low production efficiency of the hot stamping process and a low qualified rate of the final finished product. Summary of the invention

[0048] Explanation of terms or terms used in this article.

[0049] The hot stamping process is a special printing process that does not use ink. The so-called hot stamping refers to the process of hot stamping electrochemical aluminum foil onto the surface of the substrate under a certain temperature and pressure. The hot stamping machine is a device used to complete the hot stamping process.

[0050] Figure 1 A schematic diagram of the exploded structure of the cigarette label three-dimensional hot stamping device provided in an embodiment of the present invention.

[0051] See also Figure 1 An embodiment of the present invention provides a three-dimensional hot stamping device for cigarette labels, which includes a positioning plate 1, a buffer 2, a paper material layer 3, and a resin material layer 4. The positioning plate 1 includes a hollow portion 11; the contour shape of the buffer 2 matches the shape of the hollow portion 11, and the buffer 2 is located in the hollow portion 11. The paper material layer 3 includes a graphic portion 31 and a pull-out portion 32, and the graphic portion 31 and the pull-out portion 32 are fixedly connected or integrated; the graphic portion 31 is located in the hollow portion 11, and the pull-out portion 32 is located outside the hollow portion 11. The resin material layer 4 matches the overall shape of the positioning plate 1, and the resin material layer 4 is fixedly connected to the positioning plate 1. The resin material layer 4 is constructed to be transparent for easy observation.

[0052] 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 is also matched with the adaptability of hot stamping. Therefore, the positioning plate 1 can choose cardboard or a base paper with hot stamping. The positioning plate 1 is provided with a hollow portion 11, and the hollow portion 11 and the buffer 2 and the paper material layer 3 are all positioned and matched. The buffer 2 and the paper material layer 3 can be accurately inserted into the hollow portion 11, and the hollow portion 11 can provide an accurate positioning reference for the parts matched therewith, which provides a guarantee for subsequent accurate hot stamping. In addition, the hollow portion 11 makes the assembly process of the buffer 2 and the paper material layer 3 more intuitive and convenient. The operator can quickly install the parts to the correct position by observing the matching of the hollow portion 11 and the positioning component, thereby improving the installation efficiency.

[0053] The resin material layer 4 and the positioning plate 1 are fixedly connected, and specifically, the rest of the parts where the two are in contact with each other are glued and fixed. The structure formed as a whole by the resin material layer 4 and the positioning plate 1 protects the buffer 2 and the paper material layer 3. The structure formed as a whole by the resin material layer 4 and the positioning plate 1 presents a groove at the position corresponding to the hollow part 11, which also makes it easier for the buffer 2 and the paper material layer 3 to be embedded in the hollow part 11, and the fixed position is not offset or deformed.

[0054] The paper material layer 3 comprises a graphic part 31 and a drawing part 32. By utilizing the hot stamping area graphic part 31 of the paper material layer 3, the area requiring pressure adjustment can be directly and quickly located according to the product hot stamping presentation effect, the search time and the machine adjustment time can be reduced, the scrap rate can be reduced, and production efficiency can be improved. In addition, the size design of the paper material layer 3 and the buffer 2 is directly embedded in correspondence with the hollow part 11, and the overall structure of the drawing-out type is formed, which facilitates the extraction of the paper material layer 3 during pressure adjustment, and while saving time, the paper material layer 3 is also not easily damaged. In addition, the paper material layer 3 needs to possess water absorption, and the moisture or water formed by the heat generated in the hot stamping process is adsorbed and does not deform or damage. In addition, the paper material layer 3 can be repeatedly drawn and pulled, which improves the convenience and repeatability of operation.

[0055] Continue to see Figure 1 In some embodiments, the hollow portion 11 is located at the edge of the bottom, which is convenient for alignment and calibration. The edge position is easier to see and touch. During the assembly of the buffer 2 and the paper material layer 3, the operator can intuitively align the components to be installed with the hollow portion 11, which greatly improves the assembly efficiency. When the buffer 2 and the paper material layer 3 need to be taken out, the buffer 2 and the paper material layer 3 can also be easily pulled out from the hollow portion 11 without being blocked by other components, which is convenient to operate and has a large operating space.

[0056] In some embodiments, the hollow portion 11 is constructed as a trapezoid or a triangle. The edges of the trapezoid or triangular hollow portion 11 guide the installation of the buffer 2 and the paper material layer 3, and the buffer 2 and the paper material layer 3 will not be installed incorrectly, thereby ensuring the correctness of the installation of the buffer 2 and the paper material layer 3.

[0057] Continue to see Figure 1 In some embodiments, the graphic part 31 is printed with graphic marks to be printed. The graphic marks 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 sulfuric acid paper material layer 3, and the resin material layer 4 are stacked together, and the position corresponding to the graphic mark is the position where the cigarette label needs to be formed on the cigarette box. Taking the "Seven Wolves" cigarette label as an example, if the mark at the wolf's head is unclear or the color is wrong after hot stamping, the position corresponding to the wolf's head can be accurately identified through the graphic part 31. When hot stamping is performed again later, 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. In addition, there is no need to adjust the hot stamping pressure of other parts of the wolf. It can be seen that the technical solution of the embodiment of the present 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 hot stamping machine at the corresponding position so that the final three-dimensional cigarette label meets the requirements.

[0058] In some embodiments, the material of the buffer 2 is a copper sheet. The copper sheet has toughness and can buffer the pressing during the hot stamping process, so that the protective resin material layer 4 is not easy to be cracked during hot stamping, and the protective and convenient extraction and insertion of the sulfuric acid paper material layer 3 are facilitated.

[0059] The embodiment of the present invention further provides a hot stamping system, comprising a hot stamping machine and a cigarette label three-dimensional hot stamping device provided by any technical solution of the present invention. The hot stamping machine comprises a three-dimensional hot stamping base plate; and the cigarette label three-dimensional hot stamping device cooperates with the three-dimensional hot stamping base plate.

[0060] Each hot stamping machine is provided with a plurality of cigarette label 3D hot stamping devices, and each cigarette label 3D hot stamping device is independent. When the hot stamping pressure at the position corresponding to one of the cigarette label 3D hot stamping devices does not meet the requirements, only the buffer 2 and the sulphate paper material layer 3 of this cigarette label 3D hot stamping device can be removed, which will not affect the position and operation of other cigarette label 3D hot stamping devices. Therefore, the convenience of adjustment is greatly improved.

[0061] The hot stamping system provided by the above technical solution has a three-dimensional hot stamping device for cigarette labels, which solves the problem of repeated position calibration with the hot stamping plate caused by the resin sulfuric acid paper material layer 3 being lifted up as a whole due to the existing pressure compensation method, and reduces the hot stamping waste caused by inaccurate alignment. In addition, the hot stamping system adopts an embedded structure, and on the basis of achieving the stability of the overall overprint alignment, the buffer 2 and the sulfuric acid paper material layer 3 can be pulled out by the pull-out design to perform pressure compensation at the corresponding position, thereby reducing the time for adjusting the overprint alignment and also reducing the time for adjusting and finding the pressure position to be adjusted; and the overall embedded design can also solve the problem of remaking the positioning device caused by the decay and deformation of the material after the pressure compensation positioning device absorbs water to the greatest extent according to the material selection, thereby improving the utilization rate of the device. Therefore, the hot stamping system can also be used in other places and scenes. Practice has proved that this hot stamping system has the advantages of reasonable structure, low production cost, and easy installation and operation, and has good use effect in the hot stamping process.

[0069] Step S600, if the cigarette label formed by hot stamping on the surface of the cigarette box does not meet the requirements, then identify the area where the cigarette label formed by hot stamping on the surface of the cigarette box does not meet the requirements, and the area is the first area.

[0070] Step S700, pulling out the drawing portion 32 of the sulfuric acid paper material layer 3.

[0076] The three-dimensional hot stamping method for cigarette labels provided by the above technical solution can be embedded in the three-dimensional hot stamping device for cigarette labels when the operating scenario requires repeated adjustment of the three-dimensional hot stamping device for cigarette labels and material extraction. In addition, during the hot stamping process, the position where the hot stamping pressure does not meet the requirements can be quickly found, and there is no need to repeatedly calibrate and adjust the position. The calibration and adjustment time is short, and there is no need to repeatedly stop the machine. The hot stamping success rate is high, and the hot stamping production efficiency is high. In addition, the machine adjustment loss and device durability caused by repeated adjustment and material extraction are solved, and the position to be adjusted is locked quickly and efficiently, reducing the time for repeated calibration of the hot stamping plate and the resin sulfuric acid paper material layer 3 due to pressure adjustment.
