Description

Technical Field

[0001] This invention relates to the field of hot stamping technology, specifically to a hot stamping device and method for splicing paper. Background Technology

[0002] Tipping paper is primarily used to connect the cigarette filter to the cigarette body, serving as a transition and ensuring a secure bond for easy cigarette use. It is also a crucial element carrying significant information and showcasing the brand image. To enhance its aesthetics, specialized hot stamping equipment is used to firmly adhere metallic foil (usually gold, silver, or other colors) to the tipping paper surface through heating and pressure, creating specific patterns, text, or decorative elements. This enhances the product's visual appeal and thus elevates the brand image.

[0003] Roller stamping and embossing in hot stamping equipment are two different hot stamping methods, which differ in their working principles, application scenarios, and hot stamping effects.

[0004] Roller foil stamping, also known as rotary hot stamping, is a continuous hot stamping method. In this method, both the hot stamping roller (usually a heated metal roller with a printed design) and the pressure roller (for applying pressure) are rotating. The material to be stamped, such as the tipping paper, is continuously fed between the two rollers. The heat from the hot stamping roller melts the metal layer on the foil, and then, under the pressure of the pressure roller, the molten metal layer is transferred and adhered to the tipping paper, thus forming the hot stamping design. Because the entire process is continuous and rolling, high-speed and efficient hot stamping operations can be achieved.

[0005] Flatbed hot stamping is one of the main methods of embossing. Its working principle involves keeping both the hot stamping plate (a flat plate with the hot stamping pattern) and the base plate (used to support the material to be stamped) flat. During operation, the hot stamping plate is heated. When the tip paper is placed on the base plate, a pressure mechanism presses the hot stamping plate vertically downwards onto the tip paper, while the hot stamping foil is positioned between the hot stamping plate and the tip paper. Under the combined action of pressure and heat, the metallic layer of the hot stamping foil is transferred onto the tip paper, completing the hot stamping process. Each hot stamping action is intermittent; that is, after one hot stamping operation, the hot stamping plate needs to be lifted, the next tip paper placed in, and then the next hot stamping operation can begin.

[0006] Flatbed hot stamping achieves high pattern accuracy during the hot stamping process, but its efficiency is low due to its intermittent operation. Roller hot stamping, on the other hand, is highly efficient due to its continuous rolling characteristics, but its hot stamping pattern accuracy is insufficient. Therefore, this invention provides a splicing paper hot stamping device and method. Summary of the Invention

[0007] To address the aforementioned shortcomings of existing technologies, this invention provides a splicing paper hot stamping device and method that combines the advantages and disadvantages of flatbed hot stamping and roller hot stamping, improving work efficiency while ensuring high pattern accuracy.

[0008] The present invention provides the following technical solution: a paper hot stamping device, comprising a base and a slide groove formed on the base, wherein the slide groove is provided with slidable movable platforms A, B, and C, wherein movable platform B is fixed in the slide groove by bolts, wherein movable platforms A, B, and C are provided with circulating tracks, wherein hot stamping plates are installed on several sets of slides on the circulating tracks of movable platforms A and C, and wherein heating plates are installed on several sets of slides on the circulating tracks of movable platform B, wherein the hot stamping plates on movable platforms A and C and the heating plates on movable platform B are symmetrically distributed vertically;

[0009] Both ends of the slide are equipped with fixed platforms, and each of the two fixed platforms is equipped with an electric cylinder, which pushes movable platform A and movable platform C to move within the slide.

[0010] The base is equipped with an adjusting roller group located at the end of the B movable platform. The paper is introduced between the A movable platform and the B movable platform, and is clamped and hot-stamped by several sets of hot stamping plates and heating plates while maintaining the distance. Finally, it is exported and adjusted by the adjusting roller group. The paper is then introduced between the B movable platform and the C movable platform, so that several sets of hot stamping plates and heating plates clamp and hot-stamp the unhot-stamped part of the paper.

[0011] The base is equipped with A guide rollers and B guide rollers for guiding and dispensing the tipping paper and hot stamping film. The tipping paper and hot stamping film are guided between the A movable stage and the B movable stage by the A guide rollers, and the tipping paper and hot stamping film discharged from the B movable stage and the C movable stage are separated by the B guide rollers.

[0012] Preferably, the circulating track includes four sprockets arranged on the front and rear sides of movable platforms A, B, and C, and the four sprockets are symmetrically distributed and connected by two drive shafts. The drive shafts are driven by a motor, and a chain is provided on two adjacent sprockets. Circulating slide rails are installed on the front and rear sides of movable platforms A, B, and C. Slides are provided on the two circulating slide rails at equal intervals, and each slide is hinged to the chain through a bracket, so that the chain drives each slide to slide on the circulating slide rail.

[0013] Preferably, the hot stamping plate includes a box and several sets of rectangular frames arranged in a parallel array inside the box. Each rectangular frame is provided with several sets of elastic top posts. The top of all the elastic top posts is connected to a top plate. The top of the top plate is equipped with a hot stamping plate, and the top plate is provided with a heating plate. The heating plate heats the hot stamping plate, causing the hot stamping film to be printed onto the mounting paper according to the pattern. Each rectangular frame is inlaid with an electromagnet, and the bottom of the top plate is inlaid with iron material. When the electromagnet is energized, the top plate is attracted to the top of the box. When the hot stamping plate and the heating plate are aligned, the electromagnet is de-energized, and the elasticity of the elastic top posts causes the top plate to separate from the top of the box, allowing the hot stamping plate to come into contact with the heating plate.

[0014] Preferably, the elastic top column includes a column that penetrates the rectangular frame and slides on the rectangular frame. The column is equipped with a positioning ring and a return spring located inside the rectangular frame. Under the elasticity of the return spring, the positioning ring is positioned on the top of the inner side of the rectangular frame.

[0015] Preferably, the heating plate includes a base plate and annular grooves formed at the four corners of the base plate. A rotatable connecting plate is provided in the annular groove, and the connecting plate drives the outer edge to extend out of the annular groove. A threaded post is threadedly connected to the middle of the connecting plate. A support plate is installed at the top of the four threaded posts. The length of the threaded posts is adjusted by rotating the connecting plate to adjust the level of the support plate. The side of the base plate is provided with studs for positioning the connecting plate. The studs abut against the connecting plate. Several sets of pressure sensors are installed on the support plate, and a horizontal plate is installed on the several sets of pressure sensors. A heating plate is installed on the horizontal plate.

[0016] Preferably, heating holes A for hot air exhaust are provided at the lower front end of the A movable platform and the upper front end of the B movable platform. The hot air exhausted through the heating holes preheats the packaging paper and hot stamping film. Heating holes B for hot air exhaust are provided at the lower front end of the B movable platform and the upper front end of the C movable platform. Heat dissipation holes for fan exhaust are provided at the upper front end of the B movable platform and the lower front end of the C movable platform.

[0017] Preferably, the adjusting roller assembly includes a movable opening on the base and sliding blocks A, B, and C disposed within the movable opening. Water-cooled rollers are provided on sliding blocks A and C, and a dual-axis cylinder is installed on sliding block B. Sliding block B is fixed to the movable opening by bolts. The dual-axis cylinder pushes sliding blocks A and C to slide within the movable opening, adjusting the distance between the two water-cooled rollers so that the splicing paper and hot stamping film are clamped and hot stamped by the hot stamping plate and heating plate.

[0018] A method for hot stamping splicing paper, the specific operation is as follows:

[0019] S1. First, the distance between movable platform A and movable platform C is adjusted by two electric cylinders. Then, the circular track on movable platform A, movable platform B and movable platform C runs to make the heating plate and hot stamping plate align vertically. The pressure and level of the hot stamping plate are detected by the heating plate and adjusted by the electric cylinder.

[0020] S2. The tipping paper and hot stamping film are introduced through guide roller A, clamped and hot stamped by several sets of heating plates and hot stamping plates running on movable tables A and B, and then conveyed. After hot stamping, the tipping paper and hot stamping film are cooled by adjusting rollers and their positions are adjusted so that the unhot stamped parts of the tipping paper and hot stamping film are introduced back into movable tables B and C, clamped and hot stamped by several sets of heating plates and hot stamping plates, and then conveyed. Finally, the tipping paper and hot stamping film are separated and exported through guide roller B.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The circulating track makes the hot stamping plate and the heating plate run back and forth, clamp the splicing paper and hot stamping film at a fixed distance and perform hot stamping and conveying, which speeds up the work efficiency. In addition, the two hot stamping methods are used to hot stamp the splicing paper and hot stamping film in the gaps that are not hot stamped, avoiding material waste and achieving the efficiency of roller hot stamping.

[0023] (2) The hot stamping plate and the heating plate are symmetrically distributed on the top and bottom. With the help of the electric cylinder, the pressure is precisely controlled, which can make the feed paper be hot stamped evenly and effectively. For hot stamping designs with fine patterns and complex lines, it can also ensure the integrity and clarity of the hot stamping pattern. The heating plate can monitor the pressure in real time through the pressure sensor according to the material and thickness of the feed paper, and precisely control the pressure size to make the pressure distribution uniform during the hot stamping process, ensuring the stability and consistency of the hot stamping quality.

[0024] (3) The adjusting roller group can quickly and accurately adjust the position of the water-cooling roller according to the hot stamping position of the tipping paper and hot stamping film, so that the tipping paper and hot stamping film can be effectively hot stamped by the hot stamping plate and heating plate, avoiding waste. At the same time, the water-cooling roller can also cool down the tipping paper and hot stamping film, preventing the tipping paper from deforming or the hot stamping film from being damaged due to high temperature. This improves the adaptability of the device to tipping paper of different materials and thicknesses, thereby improving production efficiency and hot stamping quality.

[0025] (4) The heating holes and heat dissipation holes can preheat and dissipate heat from the mounting paper and hot stamping film, so that the hot stamping pattern is more firmly attached to the mounting paper. At the same time, it helps the mounting paper and hot stamping film to dry and set, thus improving product quality. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. In order to keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of known functions and known components are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0042] Please see Figure 1 A paper hot stamping device and method is mainly composed of a base 1, a slide 2, an A movable platform 3, a B movable platform 4, a C movable platform 5, a circulating track 6, a hot stamping plate 7, a heating plate 8, an adjusting roller group 9, a fixed platform 10, an electric cylinder 11, an A guide roller 12, and a B guide roller 13.

[0043] The base 1, serving as the fundamental support structure of the entire device, is made of robust and stable metal, providing a stable mounting platform for other components. A groove 2 is precisely machined into the base 1; its dimensions and precision are rigorously designed to ensure that movable stages A 3, B 4, and C 5 can slide smoothly and accurately within it. Movable stage B 4 is securely fixed to a specific position within the groove 2 using high-strength bolts, ensuring it will not shift during operation. Movable stages A 3 and C 5 can move freely within the groove 2, their movement driven by an electric cylinder 11 on a fixed platform 10. Two fixed platforms 10 are respectively installed at both ends of the groove 2, and the electric cylinder 11 is connected to movable stages A 3 and C 5. By controlling the extension and retraction of the electric cylinder 11, the positions of movable stages A 3 and C 5 can be precisely adjusted, thereby achieving flexible control of the hot stamping process.

[0044] The hot stamping plates 7 mounted on the sliding surfaces of the circulating tracks 6 on movable tables A (3) and C (5), and the heating plates 8 mounted on the sliding surfaces of the circulating tracks 6 on movable table B (4), are symmetrically distributed vertically. This arrangement ensures that the tipping paper can be hot stamped evenly and effectively during the hot stamping process. The electric cylinder 11 controls the positions of movable tables A (3) and C (5), adjusting the pressure when the hot stamping plates 7 and heating plates 8 are aligned.

[0045] See Figure 8 The circulating track 6 consists of four sprockets 61, two drive shafts, a chain 62, a circulating slide rail 63, and a sliding table 64. The four sprockets 61 are symmetrically distributed on the front and rear sides of movable platforms A 3, B 4, and C 5, and are connected by two high-precision drive shafts driven by a dedicated motor. Chains 62 are fitted onto adjacent sprockets 61, forming a stable transmission structure. Circulating slide rails 63 are also installed on the front and rear sides of movable platforms A 3, B 4, and C 5. Equally spaced sliding tables 64 are mounted on the circulating slide rails 63, each sliding table 64 hinged to the chain 62 via a bracket. When the motor drives the drive shafts to rotate, the sprockets 61 drive the chain 62 to rotate cyclically, thus allowing the sliding table 64 to slide stably on the circulating slide rail 63. For example, in actual operation, the movement speed of the sliding table 64 can be controlled by adjusting the motor speed according to the requirements 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 foil and hot stamping film are continuously fed using a plate printing method during the hot stamping process, solving the problem of intermittency in plate printing. For some hot stamping designs with intricate patterns and complex lines, the pressure plate can provide better pressure control, ensuring the integrity and clarity of the hot stamping pattern.

[0046] With the cooperation of the circulating track 6, the hot stamping plate 7 and heating plate 8 on movable table A 3 and movable table B 4 reciprocate, clamping the paper and hot stamping film at a fixed distance and performing hot stamping and conveying them, thus speeding up the work efficiency. In addition, the hot stamping plate 7 and heating plate 8 on movable table B 4 and movable table C 5 perform hot stamping and conveying the un-hot stamped parts of the paper and hot stamping film again. In this way, there is no waste in the hot stamping process, achieving the efficiency of roller hot stamping.

[0047] See Figure 9 , Figure 10 and Figure 11The hot stamping plate component 7 includes a plate box 71, a rectangular frame 72, elastic top posts 73, a top plate 74, a hot stamping plate 75, and an electromagnet 76. The plate box 71 is made of a high-temperature resistant and high-strength material, and contains several sets of parallel arrayed rectangular frames 72. Each rectangular frame 72 has several sets of elastic top posts 73, with the post body 77 penetrating the rectangular frame 72 and able to slide freely on it. A positioning ring 78 and a return spring 79 are installed on the post body 77 within the rectangular frame 72. 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, ensuring that the elastic top post 73 always maintains a certain elastic potential energy. The tops of all elastic top posts 73 are connected to the top plate 74. The top of the top plate 74 is fitted with the hot stamping plate 75, and a heating plate is embedded inside the top plate 74, which rapidly and evenly heats the hot stamping plate 75. Each rectangular frame 72 is also inlaid with an electromagnet 76, and the bottom of the top plate 74 is inlaid with iron material.

[0048] When the hot stamping plate 7 and the heating plate 8 are not aligned, the electromagnet 76 is energized, generating a strong magnetic field that firmly attracts the top plate 74 to the top of the plate holder 71, ensuring a safe distance between the hot stamping plate 75 and the heating plate 8, facilitating vertical alignment of the hot stamping plate 7 and the heating plate 8. Once aligned, the electromagnet 76 is de-energized, and under the elastic action of the elastic top post 73, the top plate 74 quickly separates from the top of the plate holder 71, allowing the hot stamping plate 75 to make tight contact with the heating plate 8, thus accurately transferring the pattern on the hot stamping film onto the mounting paper. In actual operation, the positions of movable stages A 3 and C 5 are adjusted by the electric cylinder 11, thereby adjusting the distance between the top plate 74 and the hot stamping plate 75 under the elasticity of the elastic top post 73. This adjustment of the pressure allows for adjustment of the distance between movable stages A 3 and C 5 according to the complexity and precision requirements of the hot stamping pattern, achieving the best hot stamping effect.

[0049] See Figure 12 and Figure 13 The heating plate component 8 includes a base plate 81, annular grooves 82, connecting discs 83, threaded pillars 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 thermally conductive material, with annular grooves 82 at its four corners. A rotatable connecting disc 83 is installed within each annular groove 82, with its outer edge extending out of the groove. A threaded pillar 84 is threadedly connected to the center of the connecting disc 83. The support plate 85 is mounted on the top of each of the four threaded pillars 84. By rotating the connecting discs 83, the length of the threaded pillars 84 can be precisely adjusted, thereby finely adjusting the levelness of the support plate 85.

[0050] A stud 89 for positioning the connecting plate 83 is provided on the side of the substrate 81. After the connecting plate 83 is adjusted to the appropriate position, the stud 89 is tightened to firmly press against the connecting plate 83, preventing displacement of the connecting plate 83 during operation. Several sets of high-precision pressure sensors 86 are installed on the support plate 85. A horizontal plate 87 is installed on the pressure sensor 86, and a heating plate 88 is installed on the horizontal plate 87. The heating plate 88 can quickly and evenly generate heat, providing 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 splicing paper. The pressure can be precisely controlled by adjusting the position of the connecting 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 connected, the pressure value at the four corners of the horizontal plate 87 can be detected by the pressure sensor 86. By adjusting the connecting plate 83, the horizontal plate 87 is adjusted to make the values ​​of all pressure sensors 86 consistent, thus ensuring uniform pressure distribution during the hot stamping process.

[0051] See Figure 14 The adjusting roller assembly 9 consists of sliding block A 91, sliding block B 92, sliding block C 93, and a water-cooled roller 94. A movable opening is formed in the base 1, and sliding blocks A 91, B 92, and C 93 are positioned within this opening. Sliding block B 92 is bolted to a specific position within the opening, providing stable support. Water-cooled rollers 94 are mounted on sliding blocks A 91 and C 93, respectively. A dual-axis cylinder 95 is mounted on sliding block B 92. The extension and retraction of the dual-axis cylinder 95 precisely pushes sliding blocks A 91 and C 93 within the opening, thereby adjusting the distance between the two water-cooled rollers 94. During the hot stamping process of the tipping paper, the dual-axis cylinder 95 can quickly and accurately adjust the position of the water-cooled roller 94 according to the width of the tipping paper and the hot stamping film and the requirements of the hot stamping process. This allows the parts of the tipping paper and the hot stamping film that can be hot stamped by the hot stamping plate 7 and the heating plate 8 to be clamped, avoiding waste. At the same time, the water-cooled roller 94 can also cool down the tipping paper and the hot stamping film to prevent the tipping paper from deforming or the hot stamping film from being damaged due to high temperature, thereby improving the hot stamping quality and production efficiency.

[0052] Guide rollers A and B are mounted on the base 1, located at the feed and discharge ends of the hot stamping device, respectively. Guide roller A 12 accurately guides the tipping paper and hot stamping film between movable tables A 3 and B 4. Its roller surface uses a special material and processing technology, possessing excellent wear resistance and guiding properties, ensuring the tipping paper and hot stamping film remain flat and stable upon entering the hot stamping area, preventing wrinkles or misalignment. Guide roller B 13, after hot stamping, separates and smoothly exports the tipping paper and hot stamping film. Its structure and performance match those of guide roller A 12, ensuring the exported tipping paper and hot stamping film are of good quality, facilitating subsequent processing and handling.

[0053] See Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Heating holes 14 are located at the lower front end of movable platform A (3) and the upper front end of movable platform B (4). Heating holes 15 are located at the lower front end of movable platform B (4) and the upper front end of movable platform C (5). Heat dissipation holes 16 are located at the upper front end of movable platform B (4) and the lower front end of movable platform C (5). These heating and heat dissipation holes are connected to external equipment such as hot air blowers to preheat and dissipate heat from the mounting paper and hot stamping film. Before the mounting paper and hot stamping film enter the hot stamping area, hot air is exhausted through heating holes 14 to preheat them, improving the hot stamping effect and efficiency. During the hot stamping process, the heat generated can be exhausted through the heat dissipation holes 16 to prevent heat accumulation from adversely affecting the equipment and products. After hot stamping, the hot air exhausted through heating holes 15 can further heat the mounting paper and hot stamping film, making the hot stamping pattern adhere more firmly to the mounting paper, and also aiding in the drying and setting of the mounting paper and hot stamping film.

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

[0055] First, the device is started. Based on the size of the paper and the hot stamping process requirements, the distance between movable platforms A (3) and C (5) is precisely adjusted using two electric cylinders 11 to ensure accurate alignment of the hot stamping plate 7 and the heating plate 8. Then, the circulating tracks 6 on movable platforms A (3), B (4), and C (5) begin operation. The motor drives the sprocket 61 to rotate, moving the chain 62 and the slide 64 to precisely align the heating plate 8 and the hot stamping plate 7 vertically. During the alignment process, the pressure sensor 86 on the heating plate 8 continuously monitors the pressure and levelness between it and the hot stamping plate 7, transmitting the data to the control system. If the pressure does not meet the preset requirements, the control system automatically issues a command to fine-tune the positions of movable platforms A (3) and C (5) using the electric cylinders 11, ensuring uniform pressure and consistent levelness between the hot stamping plate 7 and the heating plate 8, thus preparing for subsequent hot stamping work. If the pressure sensor 86 detects uneven pressure distribution, the operator rotates the connecting plate 83 to fine-tune the heating plate 8, ensuring uniform pressure after alignment between the heating plate 8 and the hot stamping plate 7.

[0056] The tipping paper and hot stamping film are smoothly guided in by guide roller A 12 and placed between movable tables A 3 and B 4. There, they are tightly clamped by several sets of heating plates 8 and hot stamping plates 7, and continuously conveyed by the circulating track 6. During the hot stamping process, the heating plates inside the hot stamping plates 7 rapidly heat the hot stamping plate 75, ensuring that the pattern on the hot stamping film is accurately transferred onto the tipping paper. Simultaneously, the adjusting roller group 9 precisely adjusts the position of the water-cooling roller 94 using a dual-axis cylinder 95 according to the actual conditions of the tipping paper and hot stamping film. This ensures that the tipping paper and hot stamping film remain flat and tightly packed throughout the hot stamping process. The water-cooling roller 94 also cools the tipping paper and hot stamping film to prevent deformation of the tipping paper or damage to the hot stamping film due to high temperatures.

[0057] After hot stamping, the tipping paper and hot stamping film are further positioned by adjusting roller group 9, ensuring that the un-hot-stamped portions are accurately guided back between movable tables B 4 and C 5. Several sets of heating plates 8 and hot stamping plates 7 then clamp and convey them again, completing the hot stamping process for the tipping paper. Finally, guide roller B 13 separates the tipping paper and hot stamping film, smoothly exporting them to obtain a high-quality hot-stamped tipping paper product. Throughout the operation, operators can monitor the device's operating status 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 efficient and stable hot stamping operations, while guaranteeing consistent and reliable product quality.

The scope of protection of the present invention is defined by the claims.
