Description

Technical Field

[0001] This invention relates to the field of gold and silver cardboard preparation technology, specifically to a laminating machine, a process for producing gold and silver cardboard using the equipment, and gold and silver cardboard. Background Technology

[0002] Gold and silver cardboard is a type of processed synthetic paper. It is usually made by coating a base paper with glue, laminating aluminum foil to the base paper, and finally drying and shaping it to obtain the finished product.

[0003] In this process, the aluminum foil is pressed firmly onto the base paper, causing it to passively follow the base paper to the next process. Because the adhesive layer becomes very thin due to the strong pressing, the uneven texture of the base paper is reflected on the aluminum foil through the adhesive layer, reducing the surface smoothness of the aluminum foil and affecting the quality of the finished product.

[0004] Therefore, it is necessary to develop a production process and supporting equipment that can improve the surface smoothness of gold and silver cardboard. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a laminating machine, a process for producing gold and silver cardboard using the equipment, and gold and silver cardboard, thereby improving the surface flatness of gold and silver cardboard.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laminating machine, comprising a roll film unwinding rack, a coating device, a laminating device, a drying device, and an oven arranged sequentially along an aluminum foil film conveying path. The coating device is located on one side of the laminating device, and a roll paper unwinding rack is located on the other side of the laminating device. The laminating device includes a laminating frame, a mirror roller rotatably mounted on the laminating frame, a pressing roller mounted on the laminating frame, and a first driving assembly for driving the mirror roller to rotate around an axis. The mirror roller is a heating roller. A pressing frame for mounting the pressing roller is mounted on the laminating frame. A first material feeding gap is formed between the pressing roller and the mirror roller. A gap adjustment mechanism for adjusting the first material feeding gap is provided at both ends of the pressing roller.

[0007] The present invention, possessing the above-mentioned features, includes a gap adjustment mechanism that controls the pressing force and adjusts the feed gap. By controlling the pressing force, it prevents the aluminum foil film from being pressed too hard onto the paper and also prevents the composite adhesive from being excessively thinned, causing the paper's texture to be reflected on the aluminum foil film. By adjusting the feed gap, it ensures that the thickness of the composite adhesive is greater than the thickness of the uneven paper surface, filling the paper surface during lamination and achieving a bond between the paper and the aluminum foil film, while simultaneously improving the paper's surface flatness. A mirror roller with a high surface finish is used to transport the aluminum foil film, which replicates the surface flatness of the mirror roller, ensuring the production of gold and silver cardboard with high surface flatness. The mirror roller has a heating function, improving the fluidity of the composite adhesive and making the composite adhesive fill the paper surface more evenly.

[0008] A further feature of the present invention is that the gap adjustment mechanism includes a shaft end mounting assembly sleeved on the end of the pressing roller, a bearing seat detachably connected to the shaft end mounting assembly, and a second driving assembly that drives the bearing seat toward or away from the mirror roller. A first linear guide rail is provided on the side wall of the pressing frame facing the pressing roller. The first linear guide rail is arranged along the moving direction of the bearing seat, and the slider of the first linear guide rail is fixedly connected to the bearing seat.

[0009] The present invention, which has the above features, adjusts the first material feeding gap by driving the bearing seat to move through a second driving component, and guides the movement of the bearing seat through a second linear guide rail, thereby improving the smoothness of the gap adjustment; the bearing seat and the shaft end mounting component are detachably connected, which facilitates the maintenance and replacement of the pressing roller.

[0010] A further feature of the present invention is that: the bearing housing is provided with a limiting component for limiting the pressing roller, the limiting component includes a cylinder and a connecting block that is linked to the cylinder, the connecting block is fixedly mounted on the bearing housing, the pressing frame is provided with a U-shaped groove for accommodating the bearing housing, the open end of the U-shaped groove is provided with a mounting plate, and the cylinder is fixedly mounted on the mounting plate.

[0011] The present invention, which has the above-mentioned features, prevents the pressing roller from shifting during operation by setting a limiting component, thereby ensuring that the first material feeding gap remains stable during continuous operation.

[0012] A further provision of the present invention is as follows: a paper feed guide roller is provided inside the pressing frame above the pressing roller. A first adjusting component and a second adjusting component are respectively provided at both ends of the paper feed guide roller. The first adjusting component includes a first seated bearing sleeved on the end of the paper feed guide roller, a first adjusting seat provided on the inner wall of the pressing frame, and a first handle connected to the first seated bearing. The first handle includes a first screw arranged along the moving direction of the pressing roller and a first handwheel provided at the end of the first screw. The head end of the first screw is connected to the first seated bearing. The second adjusting component includes a second seated bearing sleeved on the end of the paper feed guide roller, a second adjusting seat provided on the inner wall of the pressing frame, and a second handle connected to the second seated bearing. The second handle includes a second screw arranged in the vertical direction and a second handwheel provided at the end of the second screw. The head end of the second screw is connected to the second seated bearing.

[0013] The present invention having the above features: paper enters the laminating device under the traction of the feed guide roller; the first adjustment component can adjust the horizontal position of the feed guide roller; the second adjustment component can adjust the vertical position of the feed guide roller; by using the first adjustment component in combination or by using the second adjustment component separately, the paper feeding angle is adjusted, thereby adjusting the flatness of the paper and preventing the paper from wrinkling on the surface of the mirror roller.

[0014] A further feature of the present invention is that the drying device includes a heating seat located below the mirror roller, a fixed frame fixedly connected to the heating seat, and at least one guide rod horizontally mounted on the composite frame. The upper surface of the heating seat is an arc-shaped heating surface, and a second material feeding gap is formed between the arc-shaped heating surface and the mirror roller. One end of the guide rod is fitted with a linear bearing bushing, and the other end is fitted with a guide wheel. The linear bearing bushing is connected to the fixed frame, and the circumferential surface of the guide wheel abuts against the fixed frame.

[0015] The present invention, which has the above features, forms a second feeding gap between the arc-shaped heating surface and the mirror roller, so as to dry the paper-film composite without direct contact, thereby avoiding high temperature damage to the film; the guide rod, linear bearing bushing and guide wheel realize the position adjustment of the heating seat.

[0016] This invention also provides a process for producing gold and silver cardboard, based on the aforementioned laminating machine, comprising the following steps: S1. Mix the glue and the coating material according to the ratio, stir evenly to obtain the composite glue, and pour the composite glue into the glue box of the coating device. S2, Roll film unwinding frame unwinds roll aluminum foil film; S3. The aluminum foil film enters the coating device, where the composite adhesive is evenly coated on one side of the aluminum foil film to form a composite coating. S4. The aluminum foil film enters the laminating device, and its uncoated side is attached to the surface of the mirror roller and moves with the mirror roller. The side of the aluminum foil film coated with the laminating adhesive faces outward. S5. The roll paper unwinding frame unwinds the roll paper, and the paper and aluminum foil film are unwound and conveyed synchronously. S6. The paper enters the laminating device, with one side attached to the pressing roller. The paper moves with the pressing roller into the first feeding gap, while the aluminum foil film enters the first feeding gap with the mirror roller. S7. The size of the first feeding gap is adjusted by the gap adjustment mechanism, thereby changing the thickness of the composite coating, so that the pressing roller can press the paper onto the surface of the composite coating, realizing the initial composite of paper film and obtaining the whole paper film. S8. The paper film follows the mirror roller at the set conveying distance, and the composite coating fills the paper surface under the constant temperature heating of the mirror roller. S9. The paper film enters the drying device along with the mirror roller to achieve initial shaping. S10. The pre-shaped paper film is placed in an oven for drying and curing to obtain composite paper. S11. Roll up the composite paper to obtain gold and silver cardboard or peel off the surface film to leave the aluminum layer on the paper surface to obtain transfer gold and silver cardboard.

[0017] The present invention, possessing the above-mentioned features, states that: the paper is no longer used as a conveying reference, but passively follows the aluminum foil film; the initial bonding between the paper and the aluminum foil film is achieved through the adhesiveness of the composite coating rather than strong pressure, so that the flatness of the aluminum foil film is not constrained by the flatness of the paper surface, thus improving the quality of the gold and silver cardboard; the adhesive mixed with the coating material has a higher solid content than pure adhesive, providing support for the paper and ensuring that the paper can adhere to the composite coating under the light pressure of the pressing roller without damaging the composite coating; after the coating material and adhesive are mixed, they flow evenly under constant temperature heating of the mirror roller, filling the gaps between the paper fibers, effectively smoothing out the unevenness of the paper surface and improving the flatness of the paper surface; the uncoated surface of the aluminum foil film is attached to the outer surface of the mirror roller, replicating the high gloss of the mirror roller onto the film surface.

[0018] The present invention also provides a gold and silver cardboard, which, based on the above process, sequentially includes a base paper layer, a filling adhesive layer, and a composite film layer. The base paper layer, the filling adhesive layer, and the composite film layer are composited and shaped to form an integral structure. The filling adhesive layer is formed by mixing glue and coating material, and is filled between the base paper layer and the composite film layer. After leveling, it is filled into the fiber gaps on the surface of the base paper layer. The outer surface of the composite film layer is a high-gloss mirror finish.

[0019] The present invention, possessing the above-mentioned features, has the following characteristics: the filler adhesive layer has both adhesive and filling functions, bonding the base paper layer and the composite film layer to form a composite paper, while simultaneously filling uneven areas on the surface of the base paper layer, filling pores and pits on the surface of the base paper layer at a microscopic level, so that a flat contact surface is formed between the filler adhesive layer and the base paper layer, ensuring that the bonding between the composite film layer and the base paper layer is a surface contact, avoiding the generation of defects such as air bubbles and unevenness during the bonding process; the adhesive mixed with the coating material has a higher solid content than pure adhesive, serving as a support for the filler adhesive layer, and allowing it to adhere to the filler adhesive layer without damaging the composite coating when the base paper layer and the composite film layer are bonded.

[0020] A further feature of the present invention is that the filling adhesive layer has a preset thickness.

[0021] The present invention, which has the above-mentioned features, allows the thickness of the filling adhesive layer to be adjusted according to the surface flatness of the paper during actual production, adapting to different surface conditions of the base paper layer.

[0022] A further feature of the present invention is that the composite film layer includes an aluminum layer and a peelable protective layer covering the outside of the aluminum layer. After the peelable protective layer is removed, the aluminum layer remains on the base paper layer to obtain the transfer gold and silver cardboard.

[0023] The present invention, which has the above-mentioned features, can obtain transfer gold and silver cardstock by peeling off the peelable protective layer.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Attached Figure Description
