[0042] Embodiments

[0043] Reference Figures 1 to 3 As shown, the embodiments of the present application provide a high polymer composite film functional layer preparation equipment, comprising: unwinding device 1, coating device 2, drying device 3, laminating device 4, curing device 5 and winding device 6 connected in sequence;

[0044] It can be understood that the sequential arrangement of the unwinding device 1, the coating device 2, the drying device 3, the laminating device 4, the curing device 5 and the winding device 6 can effectively cover the entire production process of the high polymer composite film functional preparation, which is helpful to realize automatic and integrated operation, thereby improving the production efficiency.

[0045] Specifically, in some embodiments of the present application, the high-molecular composite film includes but is not limited to a film, artificial leather, synthetic leather, and the like.

[0046] Of course, the above are only some examples of the material of the high-molecular composite film, and do not specifically limit the material of the high-molecular composite film.

[0047] Optionally, the coating device 2 includes the first coating mechanism 21 and / or the second coating mechanism 22, or the coating device 2 includes the first coating mechanism 21, the second coating mechanism 22, and a pre-solidification mechanism 29 arranged between the first coating mechanism 21 and the second coating mechanism 22 to perform a pre-solidification treatment on the functional layer coating material coated on the surface of the high-molecular composite film by the first coating mechanism 21.

[0048] Understandably, the coating device 2 can include one of the first coating mechanism 21 and the second coating mechanism 22 to achieve flexible selection of the coating mode, meet the coating needs of different high-molecular composite films and functional layer coating materials, and enhance the versatility and adaptability of the functional layer preparation equipment for the high-molecular composite film.

[0049] The coating device 2 can also include the first coating mechanism 21 and the second coating mechanism 22, and the pre-solidification mechanism 29 is connected between the first coating mechanism 21 and the second coating mechanism 22. The pre-solidification mechanism 29 can perform a pre-solidification treatment on the functional layer coating material coated on the surface of the high-molecular composite film by the first coating mechanism 21, so that the functional layer coating material is solidified and attached to the surface of the high-molecular composite film to avoid the flow of the functional layer coating material. Then, the surface of the high-molecular composite film with a layer of functional layer coating material attached is coated again by the second coating mechanism 22. In this way, multiple and layered coating of the functional layer coating material on the high-molecular composite film can be achieved, and the structural arrangement of the first coating mechanism 21 and the second coating mechanism 22 also helps to achieve different coating effects, thereby improving the coating quality and uniformity of the functional layer.

[0050] Of course, the coating device 2 includes the first coating mechanism 21 or the second coating mechanism 22, or the coating device 2 includes the first coating mechanism 21, the second coating mechanism 22, and the pre-solidification mechanism 29.

[0051] For example, the pre-solidification mechanism 29 can be a UV curing machine or a thermal curing structure.

[0052] More specifically, in some embodiments of the present application, the coating roller 27 of the first coating mechanism 21 is provided with a groove structure, i.e., a grooved roller; and the coating roller 27 of the second coating mechanism 22 is provided with a mesh structure, i.e., a mesh roller.

[0053] It can be understood that the coating device 2, which is equipped with a first coating mechanism 21, a second coating mechanism 22 and a pre-curing mechanism 29, can effectively improve the coating quality of the functional layer coating by coating the functional layer in stages and layers. The first coating mechanism 21 can complete the base coating and realize the thickness control of the functional layer. The second coating mechanism 22 uses a mesh roller to fill the micropores and optimize the leveling properties for the second time, thereby solving the problem of uneven porosity caused by solvent volatilization in a single coating and realizing the uniformity control of the functional layer.

[0054] More specifically, the coating roller 27 of the first coating mechanism 21 is equipped with a groove structure that effectively improves the control accuracy of the coating amount. The grooved roller surface precisely controls the coating transfer by engraving the volume ratio of the holes, thereby achieving control over the thickness of the functional layer. The groove structure also avoids wrinkles at the pressing point to a certain extent, thereby reducing damage and bubbles in the polymer composite film. The coating roller 27 of the second coating mechanism 22 is equipped with a mesh structure, which helps to eliminate lateral coating amount unevenness and further improve the uniformity of coating.

[0055] Of course, there is no limitation on whether the specific structures of the coating rollers 27 of the first coating mechanism 21 and the second coating mechanism 22 are the same.

[0056] The drying device 3 is used to completely dry or semi-dry the functional layer coating coated on the surface of the polymer composite film, so that the functional layer coating is in a semi-dry and semi-wet state, which is convenient for the subsequent attachment of the release film; the coating device 4 is used to cover the surface of the polymer composite film with a release film, which protects the functional layer coating and can also achieve high gloss or matte function on the surface of the functional layer through the transfer function of the contact surface; the curing device 5 includes a first curing mechanism 51 and / or a second curing mechanism 52, which are used to respectively cure the polymer composite film and the functional layer coating after covering the release film.

[0057] Optionally, in some embodiments of the present application, the curing device 5 may include one of the first curing mechanism 51 and the second curing mechanism 52 , or may include both the first curing mechanism 51 and the second curing mechanism 52 .

[0058] More specifically, in some embodiments of the present application, the first curing mechanism 51 is a UV curing machine, and the second curing mechanism 52 is an EB curing machine.

[0059] Among them, EB curing machines (electron beam curing equipment) are industrial equipment that use low-energy electron beam irradiation to induce rapid curing of functional layer coatings. UV curing machines are industrial equipment that use high-intensity ultraviolet (UV) light sources to achieve rapid curing of functional layer coatings through their photosensitive properties.

[0060] It can be understood that the curing device 5 can include one of the first curing mechanism 51 and the second curing mechanism 52, and due to the different implementation modes of the first curing mechanism 51 and the second curing mechanism 52, different curing needs can be met, the use flexibility is strong, and the diversified use scenarios in production and manufacturing can be met.

[0061] When the curing device 5 simultaneously includes the first curing mechanism 51 and the second curing mechanism 52, the advantages of different curing mechanisms can be complemented by designing and implementing different specific structures of the first curing mechanism 51 and the second curing mechanism 52, and the general performance of the equipment is enhanced. The first curing mechanism 51 can quickly cure the coating, which is suitable for thin coatings and requires a fast production cycle. The second curing mechanism 52 can quickly cure deep coatings, which is suitable for curing coatings that require high hardness, high temperature resistance, and chemical corrosion resistance.

[0062] Through the cooperation of the first curing mechanism 51 and the second curing mechanism 52, different characteristics of high polymer composite films and different functional layer coatings can be adapted. On the one hand, the curing effect can be quickly achieved on a deeper layer of the coating, avoiding the problem of uneven curing of the surface and deep layer of the functional layer. On the other hand, the curing speed is fast, which helps to shorten the production cycle and improve production efficiency.

[0063] In addition, the first curing mechanism 51 and the second curing mechanism 52 can also enhance the scratch resistance of the functional layer to a certain extent. Through the cooperation of the first curing mechanism 51 and the second curing mechanism 52, gradient curing of different functional modified coatings is completed, and the comprehensive performance of the functional layer is significantly improved.

[0064] Of course, the setting mode of the first curing mechanism 51 and the second curing mechanism 52 in the curing device 5, and whether the specific structures of the first curing mechanism 51 and the second curing mechanism 52 are the same are not limited, as long as the curing needs of the functional layer are met. In the specific preparation process, the first curing mechanism 51, i.e., the UV curing machine, can be used for multiple curing, and the second curing mechanism 52, i.e., the EB curing machine, can be used for once curing.

[0065] The first driving mechanism 11 is provided in the unwinding device 1, and the second driving mechanism 61 is provided in the winding device 6. The first driving mechanism 11 cooperates with the conveying mechanism 9 to transport the high polymer composite film on the unwinding device 1 to the coating device 2. The high polymer composite film released on the unwinding device 1 sequentially passes through the coating device 2, the drying device 3, the film coating device 4, and the curing device 5 for processing, and after the preparation of the functional layer, the second driving mechanism 61 is used to wind the cured high polymer composite film on the winding device 6.

[0066] It can be understood that the first drive mechanism 11 and the second drive mechanism 61 are respectively independently controlled to release and wind, and through the cooperation of the first drive mechanism 11, the second drive mechanism 61 and the conveying mechanism 9, the release and winding speed and tension of the polymer composite film by the release device 1 and the winding device 6 can be effectively coordinated, so that the polymer composite film can smoothly run between each production step, thereby improving the preparation efficiency of the functional layer of the polymer composite film and reducing the influence of factors such as stretching deformation and stretching stress on the quality.

[0067] In an optional embodiment, as shown in Figure 3 The device further comprises a corona device 7 arranged between the release device 1 and the coating device 2.

[0068] It can be understood that the corona device 7 can generate plasma through high-frequency high-voltage discharge to perform corona treatment on the surface of the polymer composite film, so that the surface of the polymer composite film is physically and chemically modified.

[0069] For example, the surface of the polymer composite film is impacted by the electron flow, which can form a micron-level rough structure, increase the surface area, enhance the “anchoring effect” of the coating material, and enhance the adhesion of the functional coating on the surface of the polymer composite film, thereby improving the connection stability of the coating and the polymer composite film, thereby helping to improve the quality of the functional layer.

[0070] For another example, the corona treatment can ionize oxygen to form ozone and active oxygen atoms, further oxidize the surface molecules of the polymer composite film, generate polar groups such as carbonyl and hydroxyl groups, so that the surface energy of the polymer composite film can be improved; the polar groups form chemical bonds with the coating material, further enhancing the bonding strength of the functional layer coating and the polymer composite film.

[0071] In an optional embodiment, in combination with Figure 3 And Figure 4 The corona device 7 comprises a high-voltage generator 71, an electrode assembly 72, an adjusting assembly 73 and a corona roller 74.

[0072] The high-voltage generator 71 is electrically connected to the electrode assembly 72, the position of the electrode assembly 72 relative to the corona roller 74 is arranged to form a high-voltage discharge area for corona treatment of the polymer composite film, the corona roller 74 is grounded, and the output end of the adjusting assembly 73 is connected to the electrode assembly 72 to drive the electrode assembly 72 to change the relative position with the corona roller 74.

[0073] The high-voltage generator 71 converts conventional power into high-frequency, high-voltage electricity, providing the energy foundation for corona discharge. The electrode assembly 72 comprises one or more high-voltage electrodes, which are sharp metal structures. The corona roller 74 is a grounded electrode that forms a discharge circuit with the high-voltage electrodes. The distance between the electrode assembly 72 and the corona roller 74 is set at 1.5-5 mm, creating a strong electric field. The high-voltage electrodes, under high voltage, ionize air molecules, generating electrons and ions, creating a corona discharge phenomenon that achieves corona treatment on polymer composite films.

[0074] It can be understood that the polymer composite film after corona treatment has better adhesion to the functional coating on the film surface and is conducive to reducing the generation of stripes and bubbles.

[0075] In an optional embodiment, combined with Figure 2 and Figure 5 As shown, the first coating mechanism 21 and the second coating mechanism 22 each include a driving member 23, a scraping member 24, a sizing member 25, a pressing roller 26 and a coating roller 27;

[0076] The pressure roller 26 is arranged close to the coating roller 27 to force the polymer composite film to adhere to the coating roller 27; the driving member 23 drives the connected coating roller 27 to rotate the coating roller 27 relative to the pressure roller 26 to apply the functional layer coating to the polymer composite film; the sizing member 25 is arranged toward the coating roller 27 to guide the functional layer coating to the coating roller 27; the scraping member 24 contacts the surface of the coating roller 27 to scrape the functional layer coating located on the surface of the coating roller 27.

[0077] It can be understood that the configuration of the first coating mechanism 21 and the second coating mechanism 22 can effectively improve the coating uniformity and accuracy. Specifically, the cooperation between the pressure roller 26 and the coating roller 27 forces the polymer composite film to closely adhere to the surface of the coating roller 27, which can, to a certain extent, prevent wrinkles or deviations in the polymer composite film caused by insufficient tension, thereby promoting uniform distribution of the functional layer coating.

[0078] The scraper 24 precisely controls the coating thickness on the coating roller 27 by adjusting contact pressure or angle, preventing partial coating buildup or insufficient coating. This can be accomplished with a scraper or flexible rubber blade. The sizing element 25 precisely guides the coating to the coating roller 27 through a quantitative feeding system. Combined with the scraper 24's residual material recovery function, this reduces coating waste. This sizing element can be implemented with a hopper or coating die.

[0079] The driving member 23 drives the coating roller 27 to drive the coating roller 27 to rotate in the opposite direction of the unwinding device 1. When the coating roller 27 rotates in the opposite direction, a high shear rate is formed on the surface of the polymer composite film, which can effectively destroy the internal structure of the thixotropic coating, reduce the viscosity of the coating, promote the leveling of the coating, and also help to improve the uniformity of the coating.

[0080] In an optional embodiment, the bottom of the coating roller 27 is also provided with a collection bin 28, which is in communication with the sizing member 25.

[0081] It can be understood that, on the one hand, the collection bin 28 can recycle the excess sizing agent, coating, or dripping residue scraped by the scraping member 24 on the surface of the coating roller 27, and return the sizing agent and the coating to the sizing member 25 through the flow guide or the pipeline, so as to realize the recycling of the sizing agent and the coating. For example, the collection bin 28 can be in communication with the sizing member 25 through the pipeline to guide the sizing agent and the coating into the sizing member 25. On the other hand, the collection bin 28 can also help to keep the workshop clean by collecting the sizing agent and the coating.

[0082] Specifically, in some embodiments of the present application, the collection bin 28 can be provided with a flow guide in communication with the sizing agent barrel of the sizing member 25, and the sizing agent can be automatically returned by gravity flow. The connection between the collection bin 28 and the sizing agent barrel can also be provided with a filter plate for intercepting bubbles and falling objects.

[0083] In an optional embodiment, as shown in Figure 2 The drying device 3 includes an electric heating pipe 31 and a heating roller 32.

[0084] It can be understood that the electric heating pipe 31 and the heating roller 32 can complement each other to achieve high-efficiency heat source. The electric heating pipe 31 can directly heat by resistance wire, which can quickly heat up in a short time and is suitable for the initial drying stage of the coating. The heating roller 32 can maintain precise control of the constant temperature stage by surface contact conduction. Through the cooperation of the electric heating pipe 31 and the heating roller 32, on the one hand, the drying speed of the coating is improved, which can to some extent avoid the problems of bubbles and uneven coating caused by the flow of the coating due to the failure to solidify in time; on the other hand, the drying parameters can be effectively controlled, which can to some extent avoid the excessive consumption of energy and improve the resource utilization efficiency.

[0085] In an optional embodiment, as shown in Figure 2 The film coating device 4 and the curing device 5 are provided with a pressing mechanism 8 for pressing the release film and the polymer composite film.

[0086] It can be understood that the setting of the pressing mechanism 8 can avoid the generation of bubbles and wrinkles by controlling the pressing of the release film and the polymer composite film and eliminating air residues during the lamination of the release film and the polymer composite film. The pressing mechanism 8 can compact the release film immediately after the film coating, which can reduce the heat energy loss to a certain extent during the curing stage.

[0087] In an optional embodiment, as shown in FIG. 1, any two adjacent devices among the unwinding device 1, the coating device 2, the drying device 3, the film coating device 4, the curing device 5 and the winding device 6 are provided with a conveying mechanism 9. Figure 2

[0088] Optionally, in some embodiments of the present application, the conveying mechanism 9 can be realized by a guide roller system, a servo motor and a worm gear system, a belt / gear transmission system, an electric sliding rail system, etc.

[0089] Of course, the above is only some examples of the conveying mechanism 9, and the specific implementation structure of the conveying mechanism 9 is not limited.

[0090] It can be understood that the conveying mechanism 9 realizes seamless connection of the polymer composite film through guide rollers, tension rollers and other components, which improves the continuity of the functional layer preparation process of the polymer composite film.

[0091] The polymer composite film functional layer preparation device provided by the embodiments of the present application can effectively improve the coating uniformity of the functional layer of the polymer composite film, effectively improve the coating and curing quality of the functional layer, and thus improve the quality and stability of the functional layer. Specifically, the device has a first coating mechanism 21 and / or a second coating mechanism 22, which can cope with different coating needs of the functional layer of the polymer composite film through one or more layered coating, effectively improve the adhesion effect of the coating, and has a first curing mechanism 51 and / or a second curing mechanism 52. On the one hand, the device can freely select the curing mode of the functional layer during the preparation process, has strong use flexibility, and on the other hand, can realize the improvement of the performance of the functional layer through gradient curing of the functional layer coating, and can also avoid the problem of uneven coating of the functional layer caused by the flow of the coating to a certain extent.
