[0002] A film laminating machine is used to laminate multiple layers of films to form a composite film product with various functions and characteristics.

[0003] For example, a film laminating machine disclosed in Chinese Patent Application No. (CN201720227935.2) includes a frame and a laminating mechanism. The laminating mechanism includes an upper pressing shaft and a lower pressing shaft. The lower pressing shaft is fixed to the frame, the upper pressing shaft slides above the lower pressing shaft, and an elastic component is connected to the upper pressing shaft to elastically press the upper pressing shaft against the lower pressing shaft. A heating component is arranged on the lower side of the lower pressing shaft and contacts the lower pressing shaft. This application heats the lower pressing shaft through the heating component to improve the lamination effect between the first film and the second film. However, after the film lamination, it is not cooled and directly wound up, which is likely to affect the quality of the film product, such as affecting the flatness of the film or generating bubbles or wrinkles, etc., and needs to be improved.

Detailed implementation mode

[0045] The following will clearly describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present application.

[0046] Embodiment 1:

[0047] This embodiment provides a film laminating machine, including:

[0048] A frame 1, on which a first unwinding reel 2, a second unwinding reel 3 and a rewinding reel 4 are installed, and a first film 5 is wound around the first unwinding reel 2, a second film 6 is wound around the second unwinding reel 3, and a composite film 7 formed by laminating the first film 5 and the second film 6 is wound around the rewinding reel 4;

[0049] A gluing mechanism 8, installed in the frame 1 and used for gluing the first film 5;

[0052] A cooling mechanism 11, installed in the frame 1 and used for cooling the composite film 7.

[0053] It can be seen from this embodiment that by setting the cooling mechanism 11, the temperature of the composite film 7 formed by laminating the first film 5 and the second film 6 is cooled, eliminating the situation that the shape is unstable due to uneven temperature and insufficient cooling after the film is wound, and there may be wavy, wrinkled or distorted conditions, improving the quality of the film product.

[0054] Embodiment 2:

[0055] This embodiment provides a film laminating machine. In addition to including the technical solutions of the above embodiments, it also has the following technical features:

[0057] Among them, the heating component 102 is used to preheat the lower pressing roller 101 and the second film 6.

[0058] It can be seen from this embodiment that by preheating both the lower pressing roller 101 and the second film 6 through the heating component 102, the laminating effect between the first film 5 and the second film 6 is prevented from being affected due to the too low temperature of the second film 6.

[0062] A heat insulation plate 1021, installed on both sides of the heating tube group 1020 and having a preheating air duct 1022 formed corresponding to the second film 6;

[0063] A first fan 1023, installed below the heating tube group 1020 and used to blow the heat generated by the heating tube group 1020 to the lower pressing roller 101 and the second film 6.

[0064] It can be seen from this embodiment that by using the heat insulation plate 1021 to form the preheating air duct 1022 corresponding to the second film 6, the lower pressing roller 101 can be preheated while the second film 6 can be preheated at the same time. The structure is simple, the manufacturing cost is low, and it has an energy-saving effect.

[0068] Among them, a second fan 111 is arranged in the cooling air duct 110, and grids 112 are arranged at both ends of the cooling air duct 110 extending outside the frame 1.

[0069] It can be seen from this embodiment that by providing a cooling air duct 110 above the composite film 7 and generating a cooling air flow through the second fan 111 to cool the composite film 7, it is convenient for the shaping of the composite film 7. Moreover, both ends of the cooling air duct 110 extend outside the frame 1 to avoid the influence of the temperature inside the laminator on the cooling air flow, and the grille 112 can protect the second fan 111.

[0070] Embodiment 5:

[0071] This embodiment provides a film laminator. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The gluing mechanism 8 includes:

[0075] Among them, the lower side of the adhesive roller 82 is located inside the glue box 80 and immersed in the glue liquid in the glue box 80.

[0076] It can be seen from this embodiment that through the first gap 83 between the pressure glue roller 81 and the adhesive roller 82, it is ensured that an equal amount of glue liquid adheres to each part of the first film 5, improving the uniformity of the glue liquid on the surface of the first film 5. At the same time, the lower side of the adhesive roller 82 is immersed in the glue liquid, and as the adhesive roller 82 rotates, the glue liquid can be brought onto the first film 5.

[0078] This embodiment provides a film laminator. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The gluing mechanism 8 further includes:

[0080] Among them, the first glue scraping plate 84 abuts against the surface of the adhesive roller 82 and is located behind the adhesive roller 82.

[0081] It can be seen from this embodiment that through the first glue scraping plate 84, it is possible to effectively remove the glue liquid remaining on the surface of the adhesive roller 82 after adhering the glue liquid to the first film 5, avoiding the glue liquid remaining on the surface of the adhesive roller 82 for a long time and solidifying on the surface of the adhesive roller 82, which affects the service life of the adhesive roller 82 and also avoids affecting the uniformity of the glue liquid on the first film 5;

[0082] The first squeegee 84 is located at the rear side of the glue applicator roller 82, and the through hole 85 on the first squeegee 84 can facilitate the return of the scraped glue liquid to the glue box 80.

[0083] Embodiment 7:

[0084] This embodiment provides a film laminating machine. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The gluing mechanism 8 further includes:

[0085] A second squeegee 86, which is installed in the frame 1 and is located above the glue box 80;

[0086] Wherein, the second squeegee 86 is located at the rear side of the glue applicator roller 82, and a second gap 87 is formed between one end of the second squeegee 86 and the first film 5.

[0087] It can be seen from this embodiment that through the setting of the second squeegee 86 and the formation of the second gap 87 between the second squeegee 86 and the first film 5, the glue liquid on the surface of the first film 5 can be smoothed, ensuring the uniformity of the glue liquid distribution on the surface of the first film 5.

[0088] Embodiment 8:

[0089] This embodiment provides a film laminating machine. In addition to including the technical solutions of the above embodiments, it also has the following technical features:

[0092] At the same time, a heating device is provided in the drying channel 90, which is a mature existing technology and will not be elaborated here.

[0093] It can be seen from this embodiment that the drying channel 90 with glue liquid is dried through the drying mechanism 9, so that the solvents (such as water, organic solvents, etc.) in the glue liquid are fully volatilized, ensuring that the glue layer is dry, facilitating the formation of an adhesive layer with a certain strength and toughness on the surface of the first film 5, and ensuring the subsequent lamination effect with the second film 6;

[0094] The baffle 91 can reduce the temperature leakage, ensure the constant temperature in the drying channel 90, and ensure the drying effect;

[0095] The plurality of support rollers 93 facilitate ensuring the flatness of the first film 5, and further ensure the uniformity and anti-cracking of the dried adhesive layer, avoiding affecting the subsequent lamination effect.
