Description

Technical Field

[0001] The present invention belongs to the technical field of anti-counterfeiting paper box preparation, and specifically relates to a preparation process for hot stamping optical variable anti-counterfeiting paper boxes. Background Art

[0002] An anti-counterfeiting paper box is a packaging container made through special designs, materials, or technologies, aiming to prevent product counterfeiting or tampering, protect brand rights and interests, and consumer interests. Its core lies in combining physical anti-counterfeiting technologies and digital technologies, making it difficult for counterfeiters to replicate, while facilitating consumers to quickly verify authenticity. An optical variable anti-counterfeiting paper box is a packaging container designed using optical color-changing materials or technologies. Through specific angles, light, or environmental changes (such as temperature), the patterns, colors, or texts on the surface of the paper box undergo reversible or irreversible visual changes, thereby achieving the anti-counterfeiting function. Such technologies can effectively prevent imitation and improve the convenience for consumers to verify authenticity. A hot stamping optical variable anti-counterfeiting paper box is a high-end packaging solution that combines the hot stamping process with optical variable anti-counterfeiting technology. By hot stamping materials with optical color-changing characteristics (such as metal foils, optical variable inks, etc.) on the surface of the paper box, a design with both tactile and visual anti-counterfeiting functions is formed. Its core feature is to utilize the metallic texture of hot stamping and the dynamic color-changing effect of the optical variable material to significantly enhance the anti-counterfeiting performance and brand recognition.

[0003] The existing preparation process for hot stamping optical variable anti-counterfeiting paper boxes has certain drawbacks when in use. When using the existing preparation process for hot stamping optical variable anti-counterfeiting paper boxes, it is usually prepared through hot stamping equipment. The hot stamping equipment generally includes flat-bed hot stamping machines, rotary die hot stamping machines, and rotary flat-bed hot stamping machines. When using a flat-bed hot stamping machine, the hot stamping plate is usually heated to a set temperature, and then the hot stamping foil is hot-pressed onto the paper box material. During this hot stamping process, the paper box material is usually conveyed to the hot stamping seat, and the hot stamping plate and the hot stamping seat cooperate to perform the hot stamping work. However, during long-term operation, the hot stamping plate and the hot stamping seat will damage the hot stamping seat, and it is necessary to regularly disassemble and replace the hot stamping seat. Moreover, the hot stamping seat is usually made of heat-insulating materials to avoid transferring heat to the processing table, but this will waste the heat transferred by the hot stamping plate during the hot pressing process, resulting in a waste of resources and unable to meet people's needs. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art; for this purpose, the present invention proposes a preparation process for hot stamping optical variable anti-counterfeiting paper boxes.

A number of groups of strengthening support rods are vertically installed between the base and the top seat. A first driving structure for controlling the lifting of the anti-counterfeiting hot stamping plate is detachably installed on the top seat, and a heating structure for heating the anti-counterfeiting hot stamping plate is provided. The heating structure can be set as temperature-controlled heating.

[0013] As a further solution of the present invention: Two groups of guiding and tensioning structures are symmetrically arranged on the base. The two groups of guiding and tensioning structures are respectively arranged on both sides of the hot stamping seat and tension the anti-counterfeiting hot stamping foil. A first conveying structure for controlling the conveyance of the anti-counterfeiting hot stamping foil is arranged on one side of the tensioning structure, and a second conveying structure for conveying the carton material is arranged on both sides of the base.

[0014] As a further solution of the present invention: The guiding and tensioning structure includes tensioning seats symmetrically arranged on the base and a number of groups of tensioning rollers arranged inside the tensioning seats for guiding and tensioning the anti-counterfeiting hot stamping foil. A second driving structure for adjusting the tensioning rollers is arranged inside the tensioning seat.

The heat recovery structure is arranged between the two support blocks and is attached to the lower end surface of the heat equalizing plate. The support block is composed of a heat conducting block attached to the heat recovery structure and a heat insulating block arranged outside the heat conducting block.

[0016] As a further solution of the present invention: The heat recovery structure includes a heat absorption box for adsorbing the heat on the heat equalizing plate and a heat dissipation structure installed on the inner top surface of the heat absorption box. The outer surface of the heat absorption box is respectively attached to the heat equalizing plate and the heat conducting block. The inside of the heat absorption box stores a recovery liquid for absorbing the heat of the heat absorption box and the heat dissipation structure. The recovery liquid is usually set as clear water.

[0017] As a further solution of the present invention: The heat dissipation structure includes a first heat dissipation block symmetrically arranged on the inner top surface of the heat absorption box and several groups of second heat dissipation blocks symmetrically arranged on both sides of the outer surface of the first heat dissipation block.

[0018] As a further solution of the present invention: A water inlet pipe and a water outlet pipe are respectively installed on the outer surface of the heat absorption box. Through holes matching the water inlet pipe and the water outlet pipe are arranged at the lower part of one side surface of the heat absorption box. One ends of the water inlet pipe and the water outlet pipe both extend into the interior of the base. Water pumps are detachably installed at one ends of the water inlet pipe and the water outlet pipe. A collecting structure for filtering impurities in the hot water and collecting the impurity dirt is detachably installed on the water outlet pipe.

[0019] As a further solution of the present invention: The collecting structure includes a collecting box detachably fixed to the water outlet pipe and a filter box movably installed in the collecting box. A sealing plate detachably and sealingly connected to the collecting box is arranged on one side of the filter box.

[0020] As a further solution of the present invention: A cleaning component for cleaning the heat absorption box and the heat dissipation structure is arranged inside the recycling structure. The cleaning component can clean the water scale adhered to the heat absorption box and the heat dissipation structure. Since the clear water is heated by the heat on the hot stamping seat, it is easy to cause water scale to form on the heat absorption box and the heat dissipation structure.

[0021] As a further solution of the present invention: The cleaning component includes several groups of cleaning plates movably arranged in the heat absorption box and respectively aligned with the heat absorption box and the heat dissipation structure, and a third driving structure arranged in the heat absorption box and used for controlling the cleaning plates to move horizontally back and forth. Several groups of scraping structures for scraping the water scale on the outer walls of the heat absorption box and the heat dissipation structure are movably arranged on the cleaning plates. A gap is arranged between the cleaning plates and the heat absorption box and the heat dissipation structure.

[0022] As a further solution of the present invention: The scraping structure includes several groups of rotating structures detachably installed at the edge of the cleaning plate and scraping members rotatably connected to the rotating structures. The upper end surface of the side of the scraping member away from the cleaning plate is an inclined surface.

[0023] As a further solution of the present invention: The cleaning component further includes a pressing plate movably arranged on the side of the cleaning plate close to the through hole and a connecting structure elastically connecting the cleaning plate and the pressing plate. The shape of the pressing plate is the same as that of the cleaning plate, the size of the pressing plate is smaller than that of the cleaning plate, the edge part of the pressing plate fits with the outer surface of the scraping member, and a connecting hole matching the third driving structure is formed in the pressing plate. Among them, the third driving structure includes a driving motor detachably installed on the outer surface of the heat absorption box and a lead screw transmission device connected to the output shaft of the driving motor. One side of the heat absorption box for installing the driving motor is set to be detachable, and the internal structure of the heat absorption box can be disassembled and maintained. When the third driving structure controls the cleaning plate to move horizontally, the water flow squeezes the pressing plate, so that the pressing plate squeezes the scraping member, so that the scraping member rotates through the rotating structure, adjusts the angle of the scraping member, and enables the scraping member to clean the scale on the heat absorption box and the heat dissipation structure. When the third driving structure controls the cleaning plate to reset, under the action of the water flow and gravity, the pressing plate is separated from the scraping member, so that the scraping member rotates and does not scrape the heat absorption box and the heat dissipation structure, reducing the damage to the heat absorption box and the heat dissipation structure, and avoiding scraping the scale on the heat absorption box and the heat dissipation structure to the other side of the cleaning plate to cause accumulation.

[0024] As a further solution of the present invention: The rotating structure includes a rotating seat detachably installed on the cleaning plate and a rotating block rotatably installed on the rotating seat and fixedly connected to the scraping member. The scraping member and the rotating block can be set as an integral body.

[0025] As a further solution of the present invention: The connecting structure includes a plurality of groups of connecting pipes vertically installed on the cleaning plate and connecting rods movably arranged in the connecting pipes. One end of the connecting rod far from the connecting pipe is provided with a connecting block connected to the pressing plate, and the other end of the connecting rod is elastically connected to the connecting pipe.

[0026] As a further solution of the present invention: A plurality of groups of guiding blocks are arranged in a circular array at the other end of the connecting rod. A guiding groove matching the guiding blocks is arranged in the connecting pipe. A spring connected to the guiding blocks is arranged on the inner wall of the connecting pipe. The spring and the guiding blocks are used in cooperation to enable the connecting rod to elastically move in the connecting pipe, and enable the pressing plate to elastically move on the cleaning plate through the cooperation of the connecting rod and the spring.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] (1) Through the stamping base and recycling structure provided in the present invention, the heat on the anti-counterfeiting stamping plate is transferred to the heat absorption box by the cooperation of the stamping bottom plate, the heat equalizing plate and the heat conducting block. The heat absorption box, the first heat dissipation block and the second heat dissipation block transfer the heat to the recycling liquid, thereby recycling the heat on the stamping base, reducing heat waste. The recycled heat can be used for preheating the carton material or heating the workshop, reducing the demand for external energy input. Through the gradient heat dissipation of the heat equalizing plate and the heat conducting block, metal fatigue or deformation caused by local overheating of the stamping base is avoided, the service life of the stamping base is prolonged, and the constant temperature state of the stamping base can be assisted to maintain, reducing the influence of environmental temperature fluctuations on the stamping accuracy, making the carton material heat more evenly, and avoiding warping or cracking of the stamping layer caused by local overheating, thereby improving the yield of the anti-counterfeiting carton preparation.

[0029] (2) Through the cleaning component provided in the present invention, the driving motor, the lead screw transmission device and the cleaning plate move in the heat absorption box. When the cleaning plate moves, the water flow squeezes the extrusion plate, so that the rotating structure, the scraping part and the connecting structure cooperate to clean the impurities formed on the heat absorption box and the heat dissipation structure, improving the heat exchange efficiency, optimizing the energy recovery, and not requiring the disassembly and cleaning of the heat absorption box, prolonging the maintenance cycle of the heat absorption box. When the connecting rod, the connecting pipe and the spring cooperate to make the cleaning plate reset, the extrusion plate moves away from the cleaning plate under the action of the water flow, so that the scraping part resets, avoiding scraping the heat absorption box and the heat dissipation structure, prolonging the service life of the heat absorption box and the heat dissipation structure, and avoiding the impurities on the heat absorption box and the heat dissipation structure being scraped to the other side of the cleaning plate by the cleaning plate and the extrusion plate, causing impurity accumulation in the heat absorption box. When the third driving structure, the cleaning plate and the scraping part clean the heat absorption box and the heat dissipation structure, the water pump and the water outlet pipe cooperate to drain the liquid from the heat absorption box, accelerating the recycling of the recycling liquid, so that the collection box and the filter box cooperate to filter and recycle the impurities, preventing the impurities from depositing in the pipeline and maintaining the fluidity of the recycling liquid.

[0081] In the present invention, a plurality of groups of guiding blocks 43 are arranged in a circular array at the other end of the connecting rod 41, guiding grooves matching the guiding blocks 43 are arranged in the connecting pipes 40, and a spring 44 connected to the guiding blocks 43 is arranged on the inner wall of the connecting pipes 40. The spring 44 and the guiding blocks 43 are used in cooperation to enable the connecting rod 41 to elastically move in the connecting pipe 40, and enable the pressing plate 34 to elastically move on the cleaning plate 29 through the cooperation of the connecting rod 41 and the spring 44.

[0082] In summary, when the third driving structure 30 is activated, the driving motor 36 drives the cleaning plate 29 to move in the heat absorption box 16 through the lead screw transmission device 37, so that the cleaning plate 29 drives the scraping member 33 to move. When the recovered liquid in the heat absorption box 16 moves along with the cleaning plate 29, due to the resistance, it squeezes the extrusion plate 34. The extrusion plate 34 drives the connecting rod 41 to move in the connecting pipe 40 through the connecting block 42, so that the connecting rod 41 drives the guiding block 43 to squeeze the spring 44, causing the extrusion plate 34 to squeeze several groups of scraping members 33. When the scraping members 33 are squeezed, they drive the rotating block 39 to rotate on the rotating seat 38, so that several groups of scraping members 33 rotate to and respectively fit on the surfaces of the heat absorption box 16 and the heat dissipation structure 17. The cleaning plate 29 uses the scraping members 33 to clean the impurities adhering to the inner wall of the heat absorption box 16 and the outer surface of the heat dissipation structure 17;

[0083] When the third driving structure 30 controls the cleaning plate 29 to reset, the cleaning plate 29 moves. When the cleaning plate 29 moves and there is no force acting on the extrusion plate 34, the extrusion plate 34 will move away from the cleaning plate 29. And when the cleaning plate 29 moves, water flows through the cleaning plate 29 into the space between the cleaning plate 29 and the extrusion plate 34, so that the extrusion plate 34 moves away from the cleaning plate 29, causing the extrusion plate 34 to separate from the scraping members 33. When there is resistance from the water flow, the scraping members 33 rotate and will not scrape the heat absorption box 16 and the heat dissipation structure 17, avoiding friction between the scraping members 33 and the heat absorption box 16 and the heat dissipation structure 17, preventing damage to the heat absorption box 16 and the heat dissipation structure 17, and also preventing the cleaning plate 29 and the extrusion plate 34 from scraping the impurities on the heat absorption box 16 and the heat dissipation structure 17 to the other side of the cleaning plate 29, resulting in impurity accumulation in the heat absorption box 16;

[0084] When the third driving structure 30 uses the cleaning plate 29 and the scraping members 33 to scrape and clean the impurities on the heat absorption box 16 and the heat dissipation structure 17 again, the water pump 24 is started, and the recovered liquid in the heat absorption box 16 is pumped out through the water outlet pipe 23, so that the cleaning plate 29 and the scraping members 33 cooperate to squeeze the recovered liquid and introduce the impurities in the recovered liquid into the water outlet pipe 23, accelerating the discharge of the recovered liquid in the heat absorption box 16. The water outlet pipe 23 introduces the recovered liquid mixed with impurities into the collection structure 25, so that the filter box 27 filters and recovers the impurities and introduces the recovered liquid with heat into the user end for use, reducing heat waste.

[0085] Embodiment 4

[0086] Referring to Figure 1 - Figure 11 , this embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0087] The hot stamping base plate 13, the heat pipe 14 and the heat conducting block 20 are used in cooperation to transfer the heat on the anti-counterfeiting hot stamping plate 1 to the heat absorption box 16. The heat absorption box 16, the first heat dissipation block 18 and the second heat dissipation block 19 transfer the heat to the recycled liquid, so as to recycle the heat on the hot stamping seat 2, reduce the waste of heat, and the recycled heat can be used for preheating the carton material or heating the workshop, reducing the demand for external energy input. Through the gradient heat dissipation of the heat pipe 14 and the heat conducting block 20, the local overheating of the hot stamping seat 2 causing metal fatigue or deformation is avoided, the service life of the hot stamping seat 2 is prolonged, and the constant temperature state of the hot stamping seat 2 can be assisted to maintain, reducing the influence of environmental temperature fluctuations on the hot stamping accuracy, making the carton material heated more evenly, and avoiding warping or cracking of the hot stamping layer caused by local overheating;

[0088] The driving motor 36, the lead screw transmission device 37 and the cleaning plate 29 move in the heat absorption box 16. When the cleaning plate 29 moves, the water flow squeezes the extrusion plate 34, so that the rotating structure 32, the scraping member 33 and the connecting structure 35 cooperate to clean the impurities formed on the heat absorption box 16 and the heat dissipation structure 17, improve the heat exchange efficiency, optimize the energy recovery, and do not need to disassemble the heat absorption box 16 for cleaning, prolonging the maintenance period of the heat absorption box 16. When the connecting rod 41, the connecting pipe 40 and the spring 44 cooperate to reset the cleaning plate 29, the extrusion plate 34 is far away from the cleaning plate 29 under the action of the water flow, so that the scraping member 33 is reset, avoiding scraping the heat absorption box 16 and the heat dissipation structure 17, prolonging the service life of the heat absorption box 16 and the heat dissipation structure 17, and avoiding the cleaning plate 29 and the extrusion plate 34 scraping the impurities of the heat absorption box 16 and the heat dissipation structure 17 to the other side of the cleaning plate 29, resulting in impurity accumulation in the heat absorption box 16. When the third driving structure 30, the cleaning plate 29 and the scraping member 33 clean the heat absorption box 16 and the heat dissipation structure 17, the water pump 24 and the water outlet pipe 23 cooperate to drain the liquid from the heat absorption box 16, accelerating the recovery of the recycled liquid, so that the collection box 26 and the filter box 27 cooperate to filter and recycle the impurities, preventing the impurities from depositing in the pipeline and maintaining the fluidity of the recycled liquid.

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
