Description

Technical Field

[0001] The invention relates to the technical field of hot stamping, and in particular to a device and method for hot stamping of tipping paper. Background Art

[0002] Tipping paper is mainly used to connect the cigarette filter and the cigarette body, playing a role of transition and connection, ensuring that the two can be firmly combined, so that consumers can use cigarettes normally. At the same time, it is also a key part that carries a lot of important information and displays the brand image. In order to make it beautiful, with the help of special hot stamping equipment, the hot stamping foil with metallic luster (usually gold, silver and other colors) is firmly attached to the surface of the tipping paper through heating and pressurization, forming a specific pattern, text or decorative elements, enhancing the visual appeal of the product, thereby enhancing the brand image.

[0003] Roller hot stamping and embossing are two different hot stamping methods in hot stamping equipment. They have certain differences in working principles, application scenarios, hot stamping effects, etc.

[0004] Roller hot stamping, also known as round hot stamping, is a continuous hot stamping method. In this method, the hot stamping roller (usually a heated metal roller with a hot stamping pattern on the surface) and the pressure roller (used to apply pressure) are both in a rotating state. The hot stamping material such as the tipping paper is continuously transferred between the two rollers, and the heat of the hot stamping roller melts the metal layer on the hot stamping foil. Then, under the pressure of the pressure roller, the melted metal layer is transferred and attached to the tipping paper, thus forming a hot stamping pattern. Since the entire process is carried out in a continuous rolling process, high-speed and efficient hot stamping operations can be achieved.

[0005] Flat stamping is one of the main methods of stamping. Its working principle is to keep the stamping plate (flat plate with stamping pattern) and the base plate (used to support the material to be stamped) in a flat state. During operation, the stamping plate is heated, and when the tipping paper is placed on the base plate, the stamping plate is pressed vertically downward toward the tipping paper through the pressure mechanism, and the stamping foil is located between the stamping plate and the tipping paper. Under the combined effect of pressure and heat, the metal layer of the stamping foil is transferred to the tipping paper, completing the stamping process. Each stamping action is intermittent, that is, after completing one stamping, the stamping plate needs to be lifted, and the next tipping paper needs to be placed before the next stamping.

[0006] Flat-press hot stamping has high pattern accuracy during the hot stamping process, but its efficiency is low due to its indirect operation. Roller hot stamping has high efficiency due to its continuous rolling characteristics, but the hot stamping pattern accuracy is insufficient. Therefore, the present invention provides a device and method for hot stamping of tipping paper. Summary of the invention

[0041] In order to make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. In order to keep the following description of the embodiments of the present disclosure clear and concise, the present disclosure omits detailed descriptions of known functions and known components to avoid unnecessary confusion of the concepts of the present invention.

[0042] See also Figure 1 A device and method for hot stamping of tipping paper mainly consists of a base 1, a slide 2, a movable table A 3, a movable table B 4, a movable table C 5, a circulating track 6, a hot stamping plate 7, a heating plate 8, an adjusting roller group 9, a fixed table 10, an electric cylinder 11, a guide pair of rollers A 12 and a guide pair of rollers B 13 and other components.

[0043] The base 1 is the basic support structure of the entire device, made of a solid and stable metal material, providing a stable installation platform for other components. The slide groove 2 is precisely machined on the base 1, and the size and precision of the slide groove 2 are strictly designed to ensure that the A movable table 3, the B movable table 4 and the C movable table 5 can slide smoothly and accurately therein. The B movable table 4 is firmly fixed at a specific position in the slide groove 2 by high-strength bolts to ensure that it will not be displaced during operation. The A movable table 3 and the C movable table 5 can move freely in the slide groove 2, and their movement is driven by the electric cylinder 11 on the fixed table 10. The two fixed tables 10 are respectively installed at both ends of the slide groove 2, and the electric cylinder 11 is connected to the A movable table 3 and the C movable table 5. By controlling the extension and retraction of the electric cylinder 11, the position of the A movable table 3 and the C movable table 5 can be accurately adjusted, thereby realizing flexible control of the hot stamping process.

[0044] The hot stamping plates 7 installed on the slides of the circulating tracks 6 on the A movable table 3 and the C movable table 5, and the heating plates 8 installed on the slides of the circulating tracks 6 on the B movable table 4 are symmetrically distributed up and down. This layout ensures that the tipping paper can be hot stamped evenly and effectively during the hot stamping process. The positions of the A movable table 3 and the C movable table 5 are controlled in cooperation with the electric cylinder 11, so that the pressure is adjusted when the hot stamping plates 7 and the heating plates 8 are butted.

[0045] See also Figure 8 , the circulating track 6 is composed of four sprockets 61, two transmission shafts, a chain 62, a circulating slide rail 63 and a slide 64. The four sprockets 61 are respectively installed on the front and rear sides of the A movable platform 3, the B movable platform 4 and the C movable platform 5, and are symmetrically distributed and connected by two high-precision transmission shafts, and the transmission shafts are driven to rotate by a special motor. Chains 62 are sleeved on two adjacent sprockets 61 to form a stable transmission structure. Circulating slide rails 63 are also installed on the front and rear sides of the A movable platform 3, the B movable platform 4 and the C movable platform 5, and slides 64 with equal spacing are arranged on the circulating slide rails 63, and each slide 64 is hinged with the chain 62 through a bracket. When the motor drives the transmission shaft to rotate, the sprocket 61 drives the chain 62 to rotate in a circular manner, so that the slide 64 slides stably on the circulating slide rail 63. For example, in actual operation, the moving speed of the slide 64 can be controlled by adjusting the rotation speed of the motor according to the needs of the hot stamping process, thereby controlling the working rhythm of the hot stamping plate 7 and the heating plate 8. In this way, the tipping paper and hot stamping film are printed in a plate-printed manner and continuously transported during the hot stamping process, which solves the intermittent problem in the plate-printing process. For some hot stamping designs with fine patterns and complex lines, the pressing plate can provide better pressure control to ensure the integrity and clarity of the hot stamping pattern.

[0046] With the cooperation of the circulating track 6, the hot stamping plates 7 and the heating plates 8 on the A movable table 3 and the B movable table 4 are made to run reciprocatingly, clamping the mounting paper and the hot stamping film at a fixed distance, and hot stamping and conveying them are carried out to speed up the work efficiency. In addition, the hot stamping plates 7 and the heating plates 8 on the B movable table 4 and the C movable table 5 again hot stamp the un-hot stamped parts of the mounting paper and the hot stamping film and convey them. In this way, there is no waste in the hot stamping process, and the efficiency of roller hot stamping is achieved.

[0047] See also Fig. 9 , Fig.10 and Fig.11The hot stamping plate 7 includes a plate box 71, a rectangular frame 72, an elastic top column 73, a top plate 74, a hot stamping plate 75 and an electromagnet 76. The plate box 71 is made of a material that is resistant to high temperature and has a certain strength, and a plurality of groups of rectangular frames 72 distributed in parallel arrays are installed inside. Each rectangular frame 72 is provided with a plurality of groups of elastic top columns 73, and the column 77 of the elastic top column 73 penetrates the rectangular frame 72 and can slide freely on the rectangular frame 72. A positioning ring 78 and a return spring 79 located in the rectangular frame 72 are installed on the column 77. Under the elastic action of the return spring 79, the positioning ring 78 is tightly pressed against the top of the inner side of the rectangular frame 72, so that the elastic top column 73 always maintains a certain elastic potential energy. The top ends of all elastic top columns 73 are connected to the top plate 74, and a hot stamping plate 75 is installed on the top of the top plate 74, and a heating plate is embedded inside the top plate 74, and the hot stamping plate 75 is quickly and evenly heated by the heating plate. Each rectangular frame 72 is also inlaid with an electromagnet 76, and the bottom end of the top plate 74 is inlaid with iron material.

[0048] When the hot stamping plate 7 and the heating plate 8 are not docked, the electromagnet 76 is powered on to generate a strong magnetic field, which tightly adsorbs the top plate 74 to the top of the plate box 71, ensuring that the hot stamping plate 75 and the heating plate 8 maintain a certain safe distance, which facilitates the up-and-down docking of the hot stamping plate 7 and the heating plate 8; when the hot stamping plate 7 and the heating plate 8 are docked, the electromagnet 76 is powered off, and under the elastic action of the elastic top column 73, the top plate 74 is quickly separated from the top of the plate box 71, so that the hot stamping plate 75 is closely in contact with the heating plate 8, so that the pattern on the hot stamping film is accurately printed on the tipping paper. In actual operation, the position of the A movable table 3 and the C movable table 5 is adjusted by the electric cylinder 11, so as to adjust the distance between the top plate 74 and the hot stamping plate 75 under the elasticity of the elastic top column 73, so as to adjust the pressure between the two, and the distance between the A movable table 3 and the C movable table 5 can be adjusted according to the complexity and precision requirements of the hot stamping pattern, and the pressure can be adjusted to achieve the best hot stamping effect.

[0049] See also Fig.12 and Fig.13 The heating plate 8 includes a base plate 81, an annular groove 82, a connecting plate 83, a threaded column 84, a support plate 85, a pressure sensor 86, a horizontal plate 87 and a heating plate 88. The base plate 81 is made of high-quality heat-conducting material, and an annular groove 82 is provided at its four corners. A rotatable connecting plate 83 is installed in the annular groove 82. The outer edge of the connecting plate 83 can extend from the annular groove 82, and the middle part of the connecting plate 83 is threadedly connected with a threaded column 84. The tops of the four threaded columns 84 are jointly installed with a support plate 85. By rotating the connecting plate 83, the length of the threaded column 84 can be accurately adjusted, so as to finely adjust the horizontality of the support plate 85.

[0050] On the side of the base plate 81, a stud 89 for positioning the connection plate 83 is provided. When the connection plate 83 is adjusted to a suitable position, the stud 89 is tightened to make it tightly against the connection plate 83 to prevent the connection plate 83 from being displaced during operation. Several groups of high-precision pressure sensors 86 are installed on the support plate 85, and a horizontal plate 87 is installed on the pressure sensor 86. A heating plate 88 is installed on the horizontal plate 87. The heating plate 88 can generate heat quickly and evenly to provide a stable heat source for the hot stamping process. In actual use, the pressure between the heating plate 8 and the hot stamping plate 7 can be monitored in real time by the pressure sensor 86 according to the material and thickness of the tipping paper, and the pressure can be accurately controlled by adjusting the position of the connection plate 83 to ensure the stability and consistency of the hot stamping quality. After the hot stamping plate 7 and the heating plate 8 are docked, the pressure values ​​at the four corners of the horizontal plate 87 can be detected by the pressure sensor 86. By adjusting the connection plate 83, the horizontal plate 87 is adjusted to keep the values ​​of all the pressure sensors 86 consistent, so that the pressure distribution is uniform during the hot stamping process.

[0051] See also Fig.14 The adjusting roller group 9 is composed of an A sliding block 91, a B sliding block 92, a C sliding block 93 and a water-cooled roller 94. A movable opening is opened on the base 1, and the A sliding block 91, the B sliding block 92 and the C sliding block 93 are arranged in the movable opening, wherein the B sliding block 92 is fixed at a specific position in the movable opening by bolts, playing a stable supporting role. The A sliding block 91 and the C sliding block 93 are respectively installed with a water-cooled roller 94, and the B sliding block 92 is installed with a double-axis cylinder 95. Through the extension and contraction of the double-axis cylinder 95, the A sliding block 91 and the C sliding block 93 can be accurately pushed to slide in the movable opening, thereby adjusting the distance between the two water-cooled rollers 94. During the hot stamping process of the tipping paper, according to the width of the tipping paper and the hot stamping film and the requirements of the hot stamping process, the double-axis cylinder 95 can quickly and accurately adjust the position of the water-cooled roller 94 so that the tipping paper and the hot stamping film can be clamped by the hot stamping plate 7 and the heating plate 8 to avoid waste. At the same time, the water-cooled roller 94 can also cool the tipping paper and the hot stamping film to prevent deformation of the tipping paper or damage to the hot stamping film due to high temperature, thereby improving the hot stamping quality and production efficiency.

[0052] The A guide pair of rollers 12 and the B guide pair of rollers 13 are installed on the base 1, and are located at the feed end and the discharge end of the hot stamping device, respectively. The A guide pair of rollers 12 is used to accurately guide the tipping paper and the hot stamping film between the A movable table 3 and the B movable table 4. Its roller surface is made of special materials and processing technology, and has good wear resistance and guidance. It can ensure that the tipping paper and the hot stamping film remain flat and stable when entering the hot stamping area, avoiding wrinkles or deviation. The B guide pair of rollers 13 is used to separate the tipping paper and the hot stamping film after the hot stamping is completed and export them smoothly. Its structure and performance match those of the A guide pair of rollers 12, which can ensure that the exported tipping paper and hot stamping film are of good quality, which is convenient for subsequent processing and handling.

[0053] See also Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , A heating holes 14 are provided at the oblique lower part of the front end of the A movable table 3 and at the oblique upper part of the front end of the B movable table 4, B heating holes 15 are provided at the oblique lower part of the end of the B movable table 4 and at the oblique upper part of the end of the C movable table 5, and heat dissipation holes 16 are provided at the oblique upper part of the front end of the B movable table 4 and at the oblique lower part of the front end of the C movable table 5. These heating holes and heat dissipation holes realize the preheating and heat dissipation functions of the butt paper and the hot stamping film by connecting to external equipment such as a hot air blower. Before the tipping paper and the hot stamping film enter the hot stamping area, the hot air is discharged through the A heating hole 14 to preheat the tipping paper and the hot stamping film, thereby improving the hot stamping effect and efficiency; during the hot stamping process, the heat generated can be discharged through the heat dissipation hole 16 to avoid the adverse effects of heat accumulation on the device and the product; after the hot stamping is completed, the hot air discharged from the B heating hole 15 can further heat the tipping paper and the hot stamping film, so that the hot stamping pattern is more firmly attached to the tipping paper, and it also helps to dry and shape the tipping paper and the hot stamping film.

[0054] A method for hot stamping of tipping paper, the specific operation is as follows:

[0055] First, start the device, and according to the size of the tipping paper and the requirements of the hot stamping process, the two electric cylinders 11 are used to accurately adjust the distance between the A movable table 3 and the C movable table 5 to ensure that the hot stamping plate 7 and the heating plate 8 can be accurately docked. Then, the circulating track 6 on the A movable table 3, the B movable table 4 and the C movable table 5 starts to run, and the motor drives the sprocket 61 to rotate, driving the chain 62 and the slide 64 to move, so that the heating plate 8 and the hot stamping plate 7 can be accurately docked up and down. During the docking process, the pressure sensor 86 on the heating plate 8 detects the pressure and level between the hot stamping plate 7 in real time, and transmits the data to the control system. If the pressure does not meet the preset requirements, the control system will automatically issue an instruction to fine-tune the position of the A movable table 3 and the C movable table 5 through the electric cylinder 11 to ensure that the pressure between the hot stamping plate 7 and the heating plate 8 is uniform and the level is consistent, so as to make full preparations for the subsequent hot stamping work. If the pressure sensor 86 detects uneven pressure distribution, the staff rotates the connecting plate 83 to fine-tune the heating plate 8 so that the pressure is uniform after the heating plate 8 and the hot stamping plate 7 are docked.

[0056] The tipping paper and the hot stamping film are smoothly introduced through the A guide roller pair 12, and after entering between the A movable table 3 and the B movable table 4, they are tightly clamped and hot stamped by the running groups of heating plates 8 and hot stamping plates 7, and continuously transported under the drive of the circulating track 6. During the hot stamping process, the heating plate inside the hot stamping plate 7 quickly heats the hot stamping plate 75, so that the hot stamping plate 75 accurately prints the pattern on the hot stamping film on the tipping paper. At the same time, the adjusting roller group 9 accurately adjusts the position of the water-cooled roller 94 through the double-axis cylinder 95 according to the actual situation of the tipping paper and the hot stamping film, ensuring that the tipping paper and the hot stamping film always remain flat and tight during the hot stamping process, and the water-cooled roller 94 cools the tipping paper and the hot stamping film to prevent deformation of the tipping paper or damage to the hot stamping film due to high temperature.

[0057] After the hot stamping, the tipping paper and the hot stamping film are further adjusted by the adjusting roller group 9, so that the un-hot stamped parts of the tipping paper and the hot stamping film are accurately introduced again between the B movable table 4 and the C movable table 5, and the several groups of heating plates 8 and hot stamping plates 7 are clamped again for hot stamping and conveying, completing the hot stamping process of the entire tipping paper. Finally, the tipping paper and the hot stamping film are separated and smoothly guided out by the B guide roller 13 to obtain a high-quality hot stamping tipping paper product. During the entire operation process, the operator can monitor the operating status of the device in real time through the control system, including parameters such as temperature, pressure, and speed, and make flexible adjustments according to actual conditions to ensure the efficient and stable hot stamping work, while ensuring the consistency and reliability of product quality.

[0058] The above embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention. The protection scope of the present invention is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present invention within the essence and protection scope of the present invention, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present invention.
