Description

Technical Field

[0001] This application relates to the technical field of label hot stamping processing apparatus, and in particular to a label hot stamping equipment. Background Technology

[0002] In the packaging industry, labels serve as the core carrier for conveying product information and showcasing brand image. Their decorative effect directly impacts consumers' first impression of a product. Hot stamping, with its unique heat transfer characteristics, has become a key process for enhancing the premium and personalized appeal of labels. This technology uses a heating device to precisely transfer metal foil under pressure to specific patterns or text areas on the label substrate, creating a decorative layer on the label surface that has a metallic luster, a smooth texture, and a three-dimensional feel, effectively enhancing the visual impact and perceived quality of the product packaging. However, in actual production, the thickness of label substrates varies significantly depending on product requirements. Existing hot stamping equipment often employs a fixed-stroke design for its pressing mechanism, which cannot adaptively adjust the pressing height according to the thickness of the label substrate. When processing thicker substrates, insufficient pressing height can prevent the metal foil from fully adhering to the substrate, easily resulting in incomplete hot stamping patterns and insufficient adhesion. When processing thinner substrates, excessive pressing height can cause substrate deformation, wrinkles, and even damage to the printed layer on the label surface. To address this issue, the industry currently relies heavily on manual adjustments of equipment parameters by workers. Operators must first measure the thickness of the label substrate, then change the stroke of the pressing mechanism by turning adjustment knobs on the equipment or inputting values. After adjustment, multiple trial heat treatments are required to verify the effect. This manual adjustment method not only consumes a significant amount of production time, causing equipment downtime and significantly reducing continuous production efficiency, but also increases the labor intensity of operators, especially in scenarios involving multiple batches and specifications of labels. The risk of operational errors is further increased, making it difficult to meet the stringent requirements of high-end product packaging for the stability and consistency of hot stamping processes. Utility Model Content

[0003] To overcome the limitations of existing hot stamping equipment where the pressing mechanism uses a fixed stroke design and cannot adaptively adjust the pressing height according to the thickness of the label substrate: when processing thicker substrates, if the pressing height is insufficient, the metal foil cannot fully adhere to the substrate, easily resulting in incomplete hot stamping patterns and insufficient adhesion; when processing thinner substrates, if the pressing height is too high, excessive pressure can cause the substrate to deform, wrinkle, or even damage the printing layer on the label surface, this application provides a label hot stamping equipment.

[0004] The label hot stamping equipment provided in this application adopts the following technical solution: A label hot stamping device includes a chassis, a winding assembly, a foil feeding assembly, and a hot stamping assembly. A hot stamping table is horizontally arranged on the top surface of the chassis, and a hydraulic drive assembly is arranged above the hot stamping table on the top surface of the chassis. The winding assembly is used to unwind labels through the hot stamping table. The foil feeding assembly is used to feed foil paper onto the label. The hot stamping assembly is arranged above the foil paper and is used to press the foil paper down to perform hot stamping on the label. The hot stamping assembly includes a lifting plate and a hot stamping template. The lifting plate is horizontally fixedly assembled at the bottom output end of the hydraulic drive assembly, and the hot stamping template is horizontally arranged below the lifting plate. A damping rod is vertically arranged between the hot stamping template and the lifting plate, and the upper and lower ends of the damping rod are respectively fixedly assembled on the adjacent end faces of the hot stamping template and the lifting plate. A first spring is vertically sleeved on the outside of the damping rod, and the two ends of the first spring are respectively fixed on the adjacent end faces of the hot stamping template and the lifting plate.

[0005] By adopting the above technical solution, the chassis is used for overall encapsulation and support of other components. The hot stamping station and other parts on its top surface work together to realize the hot stamping process. The rewinding assembly is used to unwind the label, ensuring that the label can pass smoothly through the hot stamping station. The foil feeding assembly is responsible for feeding the gold foil paper onto the label, allowing it to come into contact with the label during the hot stamping process. The hot stamping assembly, through the cooperation of the lifting plate and the hot stamping template, applies appropriate pressure to the gold foil paper, thereby hot stamping a gold pattern onto the label. The damping rod and the first spring play the role of buffering and adjusting the pressure, ensuring that the pressure during the hot stamping process is moderate and avoiding excessive squeezing that could damage the label or the gold foil paper. When the label and the gold foil paper pass through the hot stamping station, the hydraulic drive assembly controls the lifting plate to rise, causing the hot stamping template to press firmly against the gold foil paper, so that the gold foil paper adheres to the label under the pressure of the hot stamping station, completing the hot stamping process. The damping rod and the first spring ensure that the pressure is moderate and does not damage the label and the gold foil paper.

[0006] Optionally, the top surface of the hot stamping template is horizontally fixed with rods on both sides, and a hinge arm is provided above the rod, with the top of the hinge arm hinged to the bottom surface of the lifting plate.

[0007] By adopting the above technical solution, rod seats are horizontally fixed on both sides of the top surface of the hot stamping template. Their main function is to provide an installation position so that the hinge arm can be horizontally slidably installed on the hot stamping template.

[0008] Optionally, the bottom end of the articulated arm is hinged to a hole seat, and the hole seat is horizontally slidably inserted into the rod seat.

[0009] By adopting the above technical solution, the top end of the articulated arm is hinged to the bottom surface of the lifting plate, so that the lifting plate can move up and down within a certain range. The bottom end of the articulated arm is hinged to a hole seat, which can slide horizontally on the rod seat, thereby adjusting the tilt angle of the articulated arm.

[0010] Optionally, a second spring is horizontally fixed to one end of the hole seat, and the other end of the second spring is fixed to one end of the rod seat.

[0011] By adopting the above technical solution, a second spring is fixed at one end of the hole seat. The second spring provides a restoring force, which enables the hinge arm to automatically return to its initial position without the action of external force.

[0012] Optionally, the winding assembly includes an unwinding roller and a winding roller, which are horizontally rotatably connected to both sides of the chassis, and are used to transport the label through the hot stamping table.

[0013] By adopting the above technical solution, the unwinding roller in the take-up assembly is responsible for smoothly pulling out the labels stored on the roll and guiding them to the hot stamping table for processing, ensuring the stability and accuracy of the labels during transportation. The take-up roller is responsible for receiving the labels from the hot stamping table and winding them into a roll for subsequent processing or storage. Both are horizontally rotatably connected to both sides of the machine housing, ensuring that the labels can be smoothly transferred from the unwinding roller to the take-up roller during transportation.

[0014] Optionally, the foil feeding component includes support arms and foil feeding rollers. There are two support arms, and the two support arms are respectively horizontally fixed on the upper part of the vertical end face on both sides of the machine box. The ends of the two support arms are horizontally rotatably connected to foil feeding rollers, and the foil feeding rollers on the two support arms are used to transport the gold foil paper.

[0015] By adopting the above technical solution, the main function of the support arm is to provide installation support for the foil feeding roller, ensuring that it is stably and horizontally placed on the vertical end faces of both sides of the machine, thereby effectively supporting and guiding the conveying of gold foil paper during the foil feeding process. The foil feeding roller is used to realize the transfer of gold foil paper, and the stable operation of the paper is achieved through two horizontally rotating foil feeding rollers.

[0016] Optionally, a sliding frame is vertically fixed on the support arm, and two sliders are vertically slidably assembled on the sliding frame. A pressure hydraulic cylinder is vertically fixed at both the upper and lower ends of the sliding frame, and the output end of the pressure hydraulic cylinder is fixed on the slider.

[0017] By adopting the above technical solution, the sliding frame is fixed on the support arm, providing a vertical lifting guide rail for the slider, enabling the slider to move up and down. The pressure hydraulic cylinder pushes the slider up and down, thereby adjusting the pressure of the pressure guide roller on the gold foil paper, ensuring that under the temperature and pressure of the hot stamping table, the gold foil can be evenly applied to the paper to form the desired pattern.

[0018] Optionally, a pressure guide roller is horizontally rotatably connected to the slider, and the pressure guide roller guides the gold foil paper through the hot stamping table.

[0019] By adopting the above technical solution, the pressure guide roller moves up and down under the drive of the slider, precisely controlling the pressure on the gold foil paper, and achieving fine control and stable pressing of the gold foil.

[0020] In summary, this application includes at least one of the following beneficial technical effects: Through a floating adjustment structure combining springs, damping, and a hinged arm, automatic adaptation of the pressing height is achieved. During hot stamping, the hydraulic drive component pushes the lifting plate downwards, causing the hot stamping template to press the gold foil against the label substrate. When processing thicker label substrates, the reaction force of the substrate on the hot stamping template increases, pushing the hot stamping template upwards relative to the lifting plate. This causes the first spring to compress and deform, the damping slide to contract, and simultaneously the hinged arm drives the hole seat to slide along the rod seat and stretch the second spring. Conversely, when processing thinner label substrates, the reaction force is smaller, the deformation of the first and second springs decreases, and the hot stamping template moves downwards a greater distance relative to the lifting plate. This floating adjustment design requires no manual intervention and can automatically adjust the actual pressing height of the hot stamping template according to the thickness of the label substrate, covering substrates of different thicknesses. This solves the adaptation problem of insufficient pressing on thick substrates and excessive pressure on thin substrates in existing equipment, meeting the diverse needs of hot stamping for various label specifications in the packaging industry.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] This application discloses a label hot stamping device. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A label hot stamping device includes a housing 1, a take-up assembly 2, a foil feeder 3, and a hot stamping assembly 4. A hot stamping table is horizontally mounted on the top surface of the housing 1, and a hydraulic drive assembly is mounted above the hot stamping table on the top surface of the housing 1. The take-up assembly 2 is mounted on the top surface of the housing 1 and is used to unwind labels through the hot stamping table. The foil feeder 3 is mounted on the top surface of the housing 1 and is used to feed gold foil paper onto the labels. The hot stamping assembly 4 is positioned above the gold foil paper and is used to press the gold foil paper down to perform hot stamping on the labels. The hot stamping assembly 4 includes a lifting plate 41 and a hot stamping template 42. The lifting plate 41 is horizontally fixedly assembled at the bottom output end of the hydraulic drive assembly, and the hot stamping template 42 is horizontally arranged below the lifting plate 41. A damping rod 43 is vertically arranged between the hot stamping template 42 and the lifting plate 41, and the upper and lower ends of the damping rod 43 are respectively fixedly assembled on the adjacent end faces of the hot stamping template 42 and the lifting plate 41. A first spring 44 is vertically sleeved on the outside of the damping rod 43, and the two ends of the first spring 44 are respectively fixed on the adjacent end faces of the hot stamping template 42 and the lifting plate 41.

[0025] By adopting the above technical solution, the chassis 1 is used for overall encapsulation and support of other components. The hot stamping station and other components on its top surface work together to realize the hot stamping process. The rewinding assembly 2 is used to unwind the label, ensuring that the label can pass smoothly through the hot stamping station. The foil feeding assembly 3 is responsible for feeding the gold foil paper onto the label, allowing it to come into contact with the label during the hot stamping process. The hot stamping assembly 4, through the cooperation of the lifting plate 41 and the hot stamping template 42, applies appropriate pressure to the gold foil paper, thereby hot stamping a gold pattern on the label. The damping rod 43 and the first spring 44 play the role of buffering and adjusting the pressure, ensuring that the pressure during the hot stamping process is moderate and avoiding excessive squeezing that could damage the label or the gold foil paper. When the label and the gold foil paper pass through the hot stamping station, the lifting plate 41 is raised by the hydraulic drive assembly, causing the hot stamping template 42 to press tightly against the gold foil paper, so that the gold foil paper adheres to the label under the pressure of passing through the hot stamping station, completing the hot stamping process. The damping rod 43 and the first spring 44 ensure that the pressure is moderate and does not damage the label and the gold foil paper.

[0026] Reference Figure 4The hot stamping template 42 has horizontally fixed rod seats 45 on both sides of its top surface, and a hinge arm 47 is provided above the rod seat 45. The top end of the hinge arm 47 is hinged to the bottom surface of the lifting plate 41. The rod seats 45 on both sides of the top surface of the hot stamping template 42 provide an installation position so that the hinge arm 47 can be horizontally slidably installed on the hot stamping template. The bottom end of the hinge arm 47 is hinged to a hole seat 471, which is horizontally slidably inserted into the rod seat 45. The top end of the hinge arm 47 is hinged to the bottom surface of the lifting plate 41, allowing the lifting plate 41 to move up and down within a certain range. The hole seat 471 can slide horizontally on the rod seat 45, thereby adjusting the tilt angle of the hinge arm 47. A second spring 46 is horizontally fixed to one end of the hole seat 471, and the other end of the second spring 46 is fixed to one end of the rod seat 45. A second spring 46 is fixed to one end of the hole seat 471. The second spring 46 provides a restoring force, so that the hinge arm 47 can automatically return to the initial position without the action of external force.

[0027] Reference Figure 3 The winding assembly 2 includes an unwinding roller 21 and a winding roller 22, which are horizontally rotatably connected to both sides of the housing 1. The unwinding roller 21 and winding roller 22 are used to transport labels through the hot stamping table. The unwinding roller 21 in the winding assembly 2 is responsible for smoothly pulling out the labels stored on the roll and guiding them to the hot stamping table for processing, ensuring the stability and accuracy of the labels during transport. The winding roller 22 is responsible for receiving the labels from the hot stamping table and winding them into a roll for subsequent processing or storage. Both are horizontally rotatably connected to both sides of the housing 1, ensuring that the labels can be smoothly transferred from the unwinding roller 21 to the winding roller 22 during transport.

[0028] Reference Figure 5The foil feeding component 3 includes two support arms 31 and two foil feeding rollers 32. Two support arms 31 are horizontally fixed to the upper part of the vertical end faces on both sides of the machine housing 1. Each support arm 31 has a foil feeding roller 32 horizontally rotatably connected to its end. The foil feeding rollers 32 on the two support arms 31 are used to transport the gold foil paper. The main function of the support arms 31 is to provide mounting support for the foil feeding rollers 32, ensuring they are stably placed horizontally on the vertical end faces on both sides of the machine housing 1, thereby effectively supporting and guiding the transport of the gold foil paper during the foil feeding process. The foil feeding rollers 32 are used to transfer the gold foil paper, and the stable operation of the paper is achieved through the two horizontally rotatably connected foil feeding rollers 32. A sliding frame 33 is vertically fixed on the support arm 31, and two sliders 34 are vertically slidably assembled on the sliding frame 33. A pressure hydraulic cylinder 35 is vertically fixed at both the upper and lower ends of the sliding frame 33, and the output end of the pressure hydraulic cylinder 35 is fixed to the slider 34. The sliding frame 33 is fixed to the support arm 31, providing a vertical lifting guide rail for the slider 34, allowing the slider to move up and down. The pressure hydraulic cylinder 35 pushes the slider 34 up and down, thereby adjusting the pressure of the pressure guide roller 36 on the gold foil paper, ensuring that the gold foil is evenly applied to the paper and forms the desired pattern under the temperature and pressure of the hot stamping table. The pressure guide roller 36 is horizontally rotatably connected to the slider 34, and the pressure guide roller 36 guides the gold foil paper through the hot stamping table. Driven by the slider 34, the pressure guide roller 36 moves up and down, precisely controlling the pressure on the gold foil paper, achieving fine control and stable pressing of the gold foil.

[0029] The implementation principle of a label hot stamping equipment according to an embodiment of this application is as follows: First, insert the label roll into the unwinding roller 21 on one side of the machine housing 1. Then, start the motor to drive the unwinding roller 21 and the take-up roller 22 to rotate, pulling the label paper through the hot stamping table of the machine housing 1 and onto the take-up roller 22. Then, place the gold foil roll onto the foil feeding roller 32 on one side of the foil feeding component 3. Then, under the guidance of the pressure guide roller 36, the gold foil paper passes over the label on the hot stamping table of the machine housing 1 and is then collected again on the foil feeding roller 32 on the other side of the foil feeding component 3. The pressure guide roller 36 on the foil feeding component 3, supported by the pressure hydraulic cylinder 35, controls the tension of the gold foil paper supported by the pressure guide roller 36. Then, during hot stamping, the hot stamping template 42 is heated, activating the hydraulic drive assembly to extend and press the hot stamping assembly 4 downwards. As it moves downwards, the lifting plate 41 moves downwards, causing the hot stamping template 42 to move downwards and press the hot stamping foil onto the label. At the same time, to accommodate the thickness requirements of different label papers, the lifting plate 41 moves downwards, causing the hot stamping template 42 to move downwards and press the hot stamping foil onto the label. The downward pressure causes the first spring 44 between the hot stamping template 42 and the lifting plate 41 to deform and the damping slide bar 43 to extend. When the hot stamping template 42 and the lifting plate 41 are pressed down, the hole seat 471 of the hinge arm 47 slides on the rod seat 45, pushing the second spring 46 to deform. This allows the hot stamping template 42 and the lifting plate 41 to float and adjust, thus accommodating the hot stamping requirements of labels with different thicknesses.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
