Description
Technical Field
[0001] This utility model relates to the field of printing technology, and more specifically, to a high-adhesion reverse hot stamping foil. Background Technology
[0002] Reverse hot stamping foil is a hot stamping technique that achieves a reverse decorative effect through a special process. Its core feature is that the foil is transferred to the recessed area or non-graphic area of the substrate, creating a visual effect that contrasts sharply with traditional hot stamping.
[0003] Currently, when reverse hot stamping foil is applied to substrates that are difficult to adhere to, the traditional approach is to increase the adhesion between the foil and the substrate, i.e., by adding thermoplastic adhesive. However, excessive adhesive in this case can reduce the surface gloss of the substrate after hot stamping, failing to highlight the technical characteristics of the reverse hot stamping foil, and making it difficult to adjust parameters within the material itself, resulting in reduced refinement and value. Therefore, we propose a high-adhesion reverse hot stamping foil. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a high-adhesion reverse hot stamping foil to solve the technical problem that the appearance of the current reverse hot stamping foil is easily affected after it is hot stamped on the substrate.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-adhesion reverse hot stamping foil, comprising a developing layer and a support layer, a coating layer, a paint layer and a thermoplastic layer arranged sequentially above it. The thermoplastic layer is provided with a plurality of injection holes for injection. A glue-spreading plate is provided on the opposite side of two adjacent injection holes on the thermoplastic layer. A glue-floating platform is provided between two adjacent glue-spreading plates. A glue-spreading groove is connected to the side of the injection hole away from the glue-spreading plate. The support layer is provided with a plurality of uniform chamfered grooves. A horizontal protrusion is provided at the break of the chamfered groove. The coating layer is provided with a plurality of unevenly filled portions. A contact portion is provided between two adjacent filled portions. A plurality of venting portions are provided on the contact portion. The paint layer is provided with a plurality of adjusting portions that cooperate with the filled portions.
[0006] Preferably, the filling portion on the coating layer is provided in a semi-circular recessed shape, and the adjusting portion on the paint layer is provided in a semi-circular protruding shape.
[0007] Preferably, the chamfered grooves on the support layer are triangularly recessed inward, and horizontal protrusions are provided on two adjacent chamfered grooves, with the top of the horizontal protrusions being horizontally positioned corresponding to the developing layer.
[0008] Preferably, the top of the glue injection hole on the thermoplastic layer is provided with an inclined glue hole bevel, and the glue hole bevel is horizontally attached to the side of the glue leveling plate corresponding to it.
[0009] Preferably, the injection hole is a through structure disposed on the thermoplastic layer, with one side corresponding to the paint layer. The injection hole is rectangular in shape, and the glue leveling groove is connected to the inclined side of the injection hole, with its depth corresponding to the top of the inclined side of the injection hole.
[0010] Preferably, the exhaust section is an irregularly arranged rectangular elliptical structure on the contact section, and the interiors of several exhaust sections are interconnected.
[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model utilizes a thermoplastic layer with several injection holes and a floating adhesive platform on its contact surface with the substrate. During adhesive application, the thermoplastic layer is positioned between the thermoplastic layer and the paint layer. The resulting adhesive is output through the injection holes. During hot stamping, the thermoplastic layer contacts the substrate, and the adhesive in the injection holes is pressed outwards by the adhesive leveling plate and floating adhesive platform. Excess adhesive is output through the adhesive leveling groove. After hot stamping, the adhesive at the bottom is evenly distributed to the floating adhesive platform and the adhesive leveling plate. Simultaneously, because the floating adhesive platform and the adhesive leveling plate on the thermoplastic layer are not fully covered, regional coverage is achieved. On substrates with low adhesion, the injection holes combined with the adhesive leveling plate and the floating adhesive platform can achieve high adhesion without affecting the overall hot stamping adhesion or the overall aesthetics.
[0012] 2. This utility model also features a support layer that adheres to the developing layer. The support layer has several uniform chamfered grooves, which reduce the area in direct contact with the developing layer. At the same time, a horizontal protrusion is provided at the end of the chamfered groove, which reduces the sharpness of the chamfered groove end without affecting the display accuracy of the developing layer. It is applicable to various materials and hot stamping techniques, and effectively reduces the need for a large amount of glue in cases of low adhesion, which would reduce the value of hot stamping.

Detailed Implementation
[0015] like Figures 1 to 6 As shown, this utility model relates to a high-adhesion reverse hot stamping foil, comprising a developing layer 100 and a support layer 110, a coating layer 120, a paint layer 130, and a thermoplastic layer 140 arranged sequentially above it. The thermoplastic layer 140 is provided with a plurality of glue injection holes 141 for glue injection. A glue leveling plate 145 is provided on the opposite side of two adjacent glue injection holes 141 on the thermoplastic layer 140. A glue floating platform 143 is provided between two adjacent glue leveling plates 145. A glue leveling groove 144 is connected to the side of the glue injection hole 141 away from the glue leveling plate 145. The support layer 110 is provided with a plurality of uniform chamfered grooves 111. A horizontal protrusion 112 is provided at the break of the chamfered groove 111. The coating layer 120 is provided with a plurality of uneven filling portions 122. A contact portion 121 is provided between two adjacent filling portions 122. A plurality of venting portions 123 are provided on the contact portion 121. The paint layer 130 is provided with a plurality of adjusting portions 131 that cooperate with the filling portions 122.
[0016] This invention utilizes a thermoplastic layer 140, whose contact surface with the substrate is equipped with several structures including glue injection holes 141 and glue floating platforms 143. During glue application, the glue is positioned between the thermoplastic layer 140 and the paint layer 130. The thermoplastic layer 140 is then applied, and the resulting glue is output through the glue injection holes 141. During hot stamping, the thermoplastic layer 140 contacts the substrate, and upon compression, the glue in the glue injection holes 141 is pushed outwards by the glue spreading plate 145 and the glue floating platforms 143. Excess glue is discharged through these platforms. After the hot stamping is completed, the glue is output through the glue distribution tank 144. The glue at the bottom is evenly distributed to the glue distribution table 143, glue distribution plate 145 and other positions. At the same time, since the glue distribution table 143 and glue distribution plate 145 on the thermoplastic layer 140 are not fully covered, regional coverage is achieved. On the low-adhesion substrate, the glue can be fixed by several glue injection holes 141 in conjunction with the glue injection of the glue distribution table 143 and glue distribution plate 145. This can achieve high adhesion without affecting the overall hot stamping adhesion and the overall aesthetics.
[0017] This utility model also features a support layer 110 that adheres to the developing layer 100. The support layer 110 has several uniformly chamfered grooves 111, which reduces the area in direct contact with the developing layer 100. At the same time, a horizontal protrusion 112 is provided at the end of the chamfered groove 111, which reduces the sharpness of the end of the chamfered groove 111 without affecting the display accuracy of the developing layer 100. It is applicable to various materials and hot stamping techniques, and effectively reduces the need for a large amount of glue in cases of low adhesion, which would reduce the value of hot stamping.
[0018] Specifically, the filling part 122 on the coating layer 120 is set in a semi-circular recessed shape, and the adjusting part 131 on the paint layer 130 is set in a semi-circular protruding shape. The semi-circular structure of the filling part 122 on the coating layer 120 improves the connection and matching degree with the adjusting part 131 on the paint layer 130, while increasing the contact area and improving the integration of paint and coating. Furthermore, the layered setting improves the three-dimensionality of the hot stamping pattern and enhances its aesthetics.
[0019] Furthermore, the chamfered grooves 111 on the support layer 110 are triangularly recessed inward, and horizontal protrusions 112 are provided on two adjacent chamfered grooves 111, with the top of the horizontal protrusions 112 being horizontally positioned corresponding to the developing layer 100. The recessed shape of the chamfered grooves 111 reduces the contact surface without affecting the overall display state of the developing layer 100. At the same time, the horizontal protrusions 112 at the ends of the chamfered grooves 111 prevent the ends from being linear, thus avoiding excessive reduction of the contact surface and reducing the contact performance between the developing layer 100 and the support layer 110, thereby improving the aesthetics.
[0020] It is worth noting that the top of the glue injection hole 141 on the thermoplastic layer 140 is provided with an inclined glue hole bevel 142, and the glue hole bevel 142 is horizontally attached to the side corresponding to the glue spreading plate 145. The glue hole bevel 142 on the thermoplastic layer 140 allows the glue to flow along this structure, reducing exposure and ensuring that after the glue is injected, it can contact the substrate based on the floating glue platform 143, glue spreading plate 145 and other structures, improving the fixation performance of the designated position. At the same time, it reduces the occurrence of excessive glue causing a decrease in aesthetics and improves the overall transparency on transparent substrates.
[0021] It is worth mentioning that the glue injection hole 141 is set in a through structure on the thermoplastic layer 140, with one side corresponding to the paint layer 130. The glue injection hole 141 has a rectangular structure. The glue leveling groove 144 is connected to the inclined side 142 of the glue hole, and its depth corresponds to the top of the inclined side 142 of the glue hole. The fact that one side of the glue injection hole 141 corresponds to the paint layer 130 makes it convenient to set the thermoplastic layer 140 directly after the paint layer 130 is set, without affecting the integrity of the thermoplastic layer 140. The glue produced is in the glue injection hole 141, waiting for the subsequent hot stamping operation, achieving high adhesion performance without adding extra glue, and without affecting the overall aesthetics.
[0022] It is worth noting that the exhaust section 123 is an irregularly arranged rectangular elliptical structure on the contact section 121, and the interiors of several exhaust sections 123 are interconnected. The interconnection of the interiors of the exhaust sections 123 facilitates the mutual communication of exhaust at different locations. Due to the characteristics of the coating layer 120 and the paint layer 130, in order to improve the overall aesthetics, their integrity is relatively high. Therefore, it is necessary to ensure the fit while preventing the gas from being unable to escape or eliminating obvious bulges. The contact section 121 with the rectangular elliptical structure can effectively exhaust or retain the gas, improving the flatness.
[0023] Working principle: This embodiment provides a high-adhesion reverse hot stamping foil. In use, a support layer 110 is provided on the surface of the developing layer 100, and a coating layer 120 is provided on the surface of the support layer 110. The coating layer 120 and the paint layer 130 cooperate with each other, and their interiors are formed by contact between the filling part 122 and the adjusting part 131. Simultaneously, during forming, the venting part 123 on the coating layer 120 vents air from the closed contact surface. Then, adhesive is applied to the surface of the paint layer 130 to bond the thermoplastic layer... 140 is set on the paint layer 130. While fixing the thermoplastic layer 140, excess glue is output through the glue injection hole 141 to the floating glue table 143 and the glue spreading plate 145, and is retained. During hot stamping, the retained glue is squeezed onto the substrate. The substrate with low adhesion is treated with high adhesion by the large amount of glue located on the glue injection hole 141. The glue located on the floating glue table 143, the glue spreading tank 144 and the glue spreading plate 145 assists in hot stamping and fixing, and finally achieves the purpose of overall hot stamping and fixing.

However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
