Description

Technical Field

[0001] This utility model belongs to the field of cold foil stamping equipment, and in particular relates to an environmentally friendly positioning device for cold foil stamping. Background Technology

[0002] Cold foil stamping is a surface finishing technique that uses pressure to bond the foil to the substrate without high-temperature heating. Ultraviolet (UV) cold foil stamping utilizes UV curing technology, offering advantages such as energy efficiency, high performance, and compatibility with various substrates. Since inkjet printing eliminates the need for hot foil stamping dies, saving on dies and being environmentally friendly, anti-counterfeiting codes are typically printed onto the foil using inkjet printing before cold foil stamping to meet the requirements of production lines.

[0003] Existing UV cold foil printing equipment generally includes a chassis, conveyor, foil roll, feeding mechanism, coding mechanism, UV curing machine, and cold foil printing mechanism. To ensure the alignment quality between the foil and the substrate, in addition to controlling the stepping frequency between them, a corresponding positioning mechanism can be installed to assist in positioning, thereby guaranteeing the quality of the cold foil printing. Utility Model Content

[0004] This utility model addresses the aforementioned inkjet UV cold foil stamping equipment by proposing a reasonably designed, environmentally friendly positioning device for cold foil stamping that improves the alignment quality between the cold foil and the substrate and is highly practical.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The environmentally friendly positioning device for cold foil stamping provided by this utility model includes a portal frame.

[0013] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0014] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0015] Examples, such as Figures 1-4 As shown, the environmentally friendly positioning device for cold foil stamping provided by this utility model is installed between the UV curing machine and the cold foil stamping mechanism of a UV cold foil stamping equipment. Specifically, it includes a gantry frame 1. Two sets of opening and closing clamping plate assemblies 2 are arranged oppositely on one side of the gantry frame 1. The opening and closing clamping plate assembly 2 is provided with an opening 3. The opening and closing clamping plate assembly 2 includes a lower clamping plate 22 connected to the gantry frame 1 and at least one upper clamping plate 21 arranged above the lower clamping plate 22. The lower clamping plate 22 includes a lower horizontal connecting section 221 and a lower clamping section 222. The lower horizontal connecting section 221 is connected to the gantry frame 1 by screws 4. The lower clamping section 222 has a V-shaped structure and its opening faces upward. The upper clamping plate 21 includes an upper horizontal connecting section 211 and an upper clamping section 212. The upper clamping section 212 has a V-shaped structure and its opening faces downward. The upper clamping section 212 cooperates with the movable opening arranged on the lower clamping section 222.

[0016] Specifically, the two sides of the gantry frame 1 are installed and fixed to the two sides of the conveyor or chassis of the UV cold foil printing equipment, providing a basic working position for the opening and closing clamp assembly 2; the side of the lower horizontal connecting section 221 is fixed to the gantry frame 1 by screws 4; the lower clamp 22 and the upper clamp 21 intersect at the movable opening position, and the movable opening provides a certain balance margin. The intersection of the two forms the opening and closing opening 3 for dynamically clamping the hot foil and the substrate. Before cold pressing, there is a small jump gap between the hot foil and the substrate. Through the dynamic clamping action of the opening and closing opening 3, the substrate can be moved to the balance position of the opening and closing opening 3, that is, the middle position of the V-shape of the opening and closing opening 3, which can make the hot foil and the substrate achieve better adhesion quality, which is conducive to ensuring the quality of cold foil printing after they enter the cold foil printing mechanism.

[0017] To prevent the end of the upper clamping section 212 from scratching the surface of the substrate, the upper clamping section 212 provided by this utility model has a horizontal section 213 extending downward toward the lower clamping section 222 at the end away from the upper horizontal connecting section 211. The horizontal section 213 has a small overhang gap with the conveying surface of the conveyor, which can prevent the substrate from sliding to the bottom of the opening and closing clamping plate assembly 2 due to displacement, and also prevent the end of the upper clamping section 212 from scratching the surface of the substrate.

[0018] To improve the positioning performance of this device, in addition to setting a positioning mechanism to position the substrate from both sides, considering that the width of the hot stamping foil and the width of the substrate may differ significantly on some production lines, this invention also provides an auxiliary structure above the substrate to limit the width of the hot stamping foil. Specifically, the inner two walls of the portal frame 1 provided by this invention are provided with lifting adjustment ports 11, and a lifting limiting mechanism 5 is provided between the lifting adjustment ports 11. The lifting limiting mechanism 5 includes a lifting shaft 51, and the lifting adjustment ports 11 cooperate with the shaft end of the lifting shaft 51. The lifting shaft 51 is provided with end plates 52 near its two ends, and the end plates 52 are provided with screw holes 53 for installing positioning screws that cooperate with the portal frame 1. The positioning screws on the two end plates 52 can be rotated to make the lifting limiting mechanism 5 press against the inner side of the portal frame 1; by adjusting the relative height of the lifting shaft 51 in the lifting adjustment ports 11, the minimum separation gap between the lifting limiting mechanism 5 and the substrate can be adjusted to avoid large-scale jumping of the substrate.

[0019] Furthermore, the lifting shaft 51 provided by this utility model is provided with a rotating sleeve 54. One end of the rotating sleeve 54 is provided with a fixed baffle 55 connected to the lifting shaft 51. The rotating sleeve 54 is provided with a translation baffle 56 at the end away from the fixed baffle 55. An adjusting baffle 57 is directly provided between the translation baffle 56 and the fixed baffle 55. The top of the adjusting baffle 57 is provided with a guide rod 58 connected to the fixed baffle 55. Adjusting bolts 59 connected to the translation baffle 56 are provided on both sides of the adjusting baffle 57. The diameter of the rotating sleeve 54 is larger than that of the lifting shaft 51, which can further reduce the jump between the lifting limit mechanism 5 and the substrate; the fixed baffle 55 is used to provide a reference surface for continuous conveying of the substrate; the translation baffle 56 is used to limit the other side of the substrate to avoid large planar swing; for hot stamping foil with a small width, the baffle 57 can be adjusted to form a limited swing range with the fixed baffle 55. If the distance between the adjusting baffle 57 and the fixed baffle 55 is further reduced, the amount of movement of the hot stamping foil can be further limited, which is conducive to meeting the bonding requirements between the hot stamping foil and the substrate.

[0020] To improve the practicality of the translation baffle 56, the top of the translation baffle 56 provided by this utility model is provided with a passage 561 that cooperates with the guide rod 58. Two symmetrically distributed arc-shaped plates 562, integral with the translation baffle 56, are provided on the end face of the translation baffle 56. The bottom of the arc-shaped plates 562 is horizontal and consistent with the bottom of the adjusting baffle 57. The passage 561 is a U-shaped structure with the opening facing upwards, ensuring that the translation baffle 56 does not collide with the guide rod 58 while moving with the adjusting baffle 57. The arc-shaped plates 562 provide connection holes for adjusting bolts 59, and the bottoms of the arc-shaped plates 562 and the adjusting baffle 57 can limit the vertical movement of the substrate surface.

[0021] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
