Description

Technical Field

[0001] This utility model belongs to the field of cold foil stamping equipment, and in particular relates to an anti-counterfeiting digital cold foil stamping device. 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. However, some problems still exist in actual use. For example, to avoid the conveyor's path to the substrate, the foil roll is usually placed on top of the chassis, but this makes it inconvenient to change the roll. Furthermore, the anti-counterfeiting codes printed on the foil by the coding mechanism are relatively small, making online spot checks difficult. Secondly, regarding the alignment quality between the foil and the substrate, in addition to controlling the stepping frequency of the foil and substrate, a corresponding positioning mechanism can be set up to assist in positioning, thereby ensuring the quality of the cold foil printing. Utility Model Content

[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 1-3 As shown, the anti-counterfeiting digital cold foil stamping device provided by this utility model includes a chassis 1, on which a conveyor 2 is installed. The conveyor belt and main transmission mechanism of the conveyor 2 are located inside the chassis 1, while the power unit of the conveyor 2 is located outside the chassis 1. Above the conveyor 2, a feeding mechanism 3, a coding mechanism 4, a UV curing machine 5, and a cold foil stamping mechanism 6 are arranged sequentially along the conveying direction of the conveyor 2. The conveyor 2 is a belt conveyor used to transport the substrate. The feeding mechanism 3 includes a feeding rack on which... The device is equipped with multiple staggered feeding rollers to form a conveying surface between the feeding rollers until the hot stamping foil is conveyed onto the substrate. The cold stamping foil moves with the substrate. The coding mechanism 4 has a lifting function and can print anti-counterfeiting digital codes onto the hot stamping foil. The UV curing machine 5 is used to cure the coding and hot stamping foil. The cold stamping foil and the substrate complete the cold stamping under the pressure of the cold stamping mechanism 6. The feeding mechanism 3, coding mechanism 4, UV curing machine 5 and cold stamping mechanism 6 are all existing mature technologies, and will not be described in detail here.

[0016] Based on this, the present invention provides a hot stamping foil roll 7 located below the conveyor 2 at one end of the chassis 1, a material guiding and reversing mechanism 8 inclined to the rear and upward direction at the top of the feeding mechanism 3, a sampling inspection mechanism 9 near the bottom of the coding mechanism 4, the sampling inspection mechanism 9 including a connecting rod 91, a threaded seat 92 rotatably engaged with the end of the connecting rod 91, a magnifying glass 93 at the end of the threaded seat 92, a positioning mechanism 10 between the UV curing machine 5 and the cold hot stamping mechanism 6, the positioning mechanism 10 including two sets of relatively distributed opening and closing clamping plate assemblies 101, the opening and closing clamping plate assemblies 101 having an opening and closing port 102 facing the conveying center line of the conveyor 2.

[0017] Specifically, a support shaft is provided at the center of the hot stamping foil roll 7, and support arms connected to the machine housing 1 are provided at both ends of the support shaft. The hot stamping foil roll 7 is positioned below the conveyor 2 for easy roll replacement. The hot stamping foil is pulled from below the conveyor 2 to the back of the feeding mechanism 3, and then introduced from the back of the feeding mechanism 3 to the conveying surface of the guiding and reversing mechanism 8. The hot stamping foil is reversed by oblique conveying. The hot stamping foil continues to be pulled downward and connects with the conveying surface of the feeding mechanism 3. This ensures continuous unwinding of the hot stamping foil roll 7 without interfering with the moving surface of the substrate. Furthermore, the magnifying glass 93 can be rotated to adjust its orientation relative to the hot stamping foil, facilitating online spot checks of small inkjet prints from the position of the magnifying glass 93. The positioning mechanism 10 provided by this utility model adopts the method of opening and closing clamping plate assembly 101, so that the substrate and the hot stamping foil can generate a tendency to stick together in opposite directions when passing through the opening and closing port 102, until entering the cold hot stamping mechanism 6 to complete the cold hot stamping, which is beneficial to improving the alignment quality of the hot stamping foil and the substrate.

[0018] To improve the connection effect of the material guiding and reversing mechanism 8 between different conveying surfaces of the hot stamping foil, the material guiding and reversing mechanism 8 provided by this utility model includes a support plate 81 connected to the feeding mechanism 3. Two inclined rollers 82 are arranged vertically and parallelly on the support plate 81. The support plate 81 has bearing seats for mounting the inclined rollers 82, and two anti-loosening nuts are provided at one end of each inclined roller 82 on both sides of the bearing seats. The inclined rollers 82 provide an effective unit width for the hot stamping foil, and their inclined nature allows the hot stamping foil to transition from the back side to the front side of the feeding mechanism 3, thereby completing effective conveying.

[0019] To improve the practicality of the magnifying glass 93, the magnifying glass 93 provided by this utility model not only allows the angle of the connecting rod 91 to be adjusted via the threaded seat 92, but also adopts a cuboid structure design, which can meet the observation requirements of anti-counterfeiting digital codes arranged in a strip during the sampling inspection process.

[0020] To improve the positioning performance of the positioning mechanism 10, the positioning mechanism 10 provided by this utility model includes a gantry frame 103, and an opening and closing clamping plate assembly 101 includes a lower clamping plate 1012 connected to the gantry frame 103 and an upper clamping plate 1011 disposed above the lower clamping plate 1012. The lower clamping plate 1012 includes a lower horizontal connecting section 10121 and a lower clamping section 10122. The lower clamping section 10122 has a V-shaped structure and its opening faces upward. The upper clamping plate 1011 includes an upper horizontal connecting section 10111 and an upper clamping section 10112. The upper clamping section 10112 has a V-shaped structure and its opening faces downward. The upper clamping section 10112 cooperates with the movable opening 10123 disposed on the lower clamping section 10122. The lower horizontal connecting section 10121 has its side screws securing the entire lower clamping plate 1012 to the gantry frame 103. The lower clamping plate 1012 and the upper clamping plate 1011 intersect at the movable opening 10123, which provides a certain balance margin. The intersection of the two forms an opening 102 for flexibly clamping the hot stamping foil and the substrate. Before cold pressing, the hot stamping foil and the substrate have a small gap. Through the dynamic clamping action of the opening 102, and with the middle position of the opening 102 being the balance position, the hot stamping foil and the substrate can achieve better adhesion quality, which is beneficial to ensuring the quality of cold stamping printing after they enter the cold stamping mechanism 6.

[0021] In conjunction with the positioning mechanism 10, the cold foil stamping mechanism 6 provided by this utility model is provided with a pre-pressure mechanism 11. The pre-pressure mechanism 11 includes a connecting arm 111, and a pre-pressure roller 112 facing the positioning mechanism 10 is provided at the end of the connecting arm 111. The connecting arm 111 is connected to the mechanical components of the cold foil stamping mechanism 6 by bolts, and can move up and down within a certain range with the loading part of the cold foil stamping mechanism 6; the pressure surface of the pre-pressure roller 112 is lower than the loading surface of the cold foil stamping mechanism 6. By pre-pressing in advance, bubbling in the middle position of the cold foil stamping can be avoided, which is beneficial to improving the quality of the cold foil stamping product.

[0022] 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.
