Description

Technical Field

[0001] The present invention relates to the technical field of aluminum-plastic film production, and specifically, to an aluminum-plastic film production device and method. Background Art

[0002] As a composite material formed by skillfully laminating aluminum foil and plastic film, the aluminum-plastic film has significant advantages. Its aluminum foil layer has excellent heat insulation and sealing performance, can efficiently block heat transfer and prevent gas penetration, creating a stable environment inside. The addition of the plastic film is the finishing touch. It makes the aluminum-plastic film get rid of the rigidity of pure aluminum foil, has good flexibility, is lighter in texture, greatly improves both portability and ease of use, and can flexibly adapt to a variety of packaging scenarios; in addition, the aluminum-plastic film is easy to cut, trim and form, and is convenient to be processed into products of different shapes and specifications. Therefore, the aluminum-plastic film is an ideal packaging material for lithium-ion batteries.

[0003] In the current industrial production process of aluminum-plastic films, the conventional method is to pre-gather key raw materials, such as aluminum foil, polyethylene terephthalate (PET) film or biaxially oriented polypropylene (BOPP) film, and suitable adhesives. Immediately afterwards, using precision coating equipment, the adhesive is evenly coated on the surface of the PET or BOPP film, laying a solid foundation for the subsequent lamination process. Finally, with the help of professional pressing machinery, the aluminum foil is closely adhered to the PET or BOPP film coated with the adhesive, and the two are seamlessly joined through the strong adhesion of the adhesive to form the finished aluminum-plastic film.

[0004] However, in the lamination link of the existing aluminum-plastic film production equipment, on the one hand, there is a lack of consideration for the preheating link, which is not convenient to preheat the aluminum-plastic film raw materials before the lamination operation, so as to activate the performance of the adhesive and optimize the material bonding degree; on the other hand, after the lamination is completed, it is not convenient to dissipate the heat of the finished aluminum-plastic film in time, which easily causes the glue to be in a semi-cured state for a long time, reducing the bonding strength of the aluminum-plastic film; in addition, during the production process of aluminum-plastic films, due to the diverse market demands and different requirements for the width of the finished aluminum-plastic film, it is usually necessary to cut it after the lamination is completed, and it is not convenient to directly adjust the width of the aluminum-plastic film as needed during the production process, which easily increases the production cost and time consumption, and has low efficiency, making it difficult to meet the requirements of modern industry for efficient and flexible production.

[0005] In view of this, we propose an aluminum-plastic film production device and method. Summary of the Invention

[0006] The purpose of the present invention is to provide an aluminum-plastic film production device and method to solve the problems raised in the above background art.

[0007] To achieve the above object, one of the objects of the present invention is to provide an aluminum-plastic film production device, including a top plate. At both ends near the bottom of the top plate, there are brackets. At one end of the bracket near the bottom, there is an aluminum foil unwinding device, and at one end of the bracket near the top, there is a film unwinding device; at one end of the bracket between the aluminum foil unwinding device and the film unwinding device, there is a coating device, and at the other end of the bracket near the center, there is a winding device. Inside the bracket, there is a heating device;

[0008] On the outer walls of both ends of the bracket, there are width-limiting components. Between the two width-limiting components and the inside of the bracket, there is a heat exchange component. One of the width-limiting components is located between the film unwinding device and the coating device, and the other width-limiting component is located on top of the winding device;

[0009] One of the width-limiting components is used to align and fit the aluminum foil and the film, and adaptively cut and adjust their widths to ensure the neatness of the fit between the aluminum foil and the film; the other width-limiting component is used to calibrate the neatness of the winding of the aluminum-plastic film after pressing; while adjusting the width of the required aluminum-plastic film, the width-limiting component also adjusts the wind contact area inside the heat exchange component; when the aluminum foil and the film pass through the heat exchange component inside one of the width-limiting components, the heat exchange component preheats the aluminum foil and the film; when the pressed aluminum-plastic film passes through the heat exchange component inside the other width-limiting component, the heat exchange component cools the aluminum-plastic film.

[0010] As a further improvement of this technical solution, the heat exchange component includes a dual-temperature air gun. At both ends on both sides of the dual-temperature air gun, there are ventilation pipes. The air body conveyed inside the ventilation pipe near the coating device is hot air, and the air body conveyed inside the ventilation pipe near the winding device is cold air.

[0011] As a further improvement of this technical solution, the ventilation pipe includes a conduit. The conduit is arranged at the output end of the dual-temperature air gun. The other end of the conduit is fixedly connected to an air pipe. The conduit is a multi-fold pipe. The conduit is arranged inside the bracket. The outer wall of the air pipe is provided with a width-limiting component. Near the center inside the air pipe, there are multiple air holes.

[0012] As a further improvement of this technical solution, the width-limiting component includes two columns. The two columns are respectively fixedly connected to both sides near one end of the bracket. Inside the column, there are two sleeves.

[0013] As a further improvement of this technical solution, one end of the sleeve is fixedly connected to a blade. One end of the blade is fixedly connected to the output shaft of a cylinder. The two cylinders are respectively fixedly connected to the upper and lower ends of the column.

[0014] As a further improvement of the technical solution, an air pipe is provided between the inner sleeves opposite to each other inside the two struts, and the sleeves and the blades can slide on the outer wall of the air pipe.

[0015] The second object of the present invention is to provide a method for operating an aluminum-plastic film production device including the above-mentioned one, comprising the following method steps:

[0016] S1. First, place appropriate aluminum foil and plastic film inside the aluminum foil unwinding device and the film unwinding device respectively. The aluminum foil passes through the coating device through the aluminum foil unwinding device and enters inside one of the heat exchange components. The plastic film enters inside one of the heat exchange components through the film unwinding device in the same way. After passing through the heating device, the aluminum foil and the plastic film pass through another heat exchange component and are finally wound on the winding device;

[0017] S2. Start the aluminum foil unwinding device, the film unwinding device and the winding device. When the aluminum foil passes through the coating device, the surface of the aluminum foil will touch the glue on the coating device, so that when the aluminum foil enters the heating device, it can adhere to the plastic film;

[0018] S3. By adjusting the position of the width limiting component on the surface of the heat exchange component, limit and cut the widths of the aluminum foil and the plastic film passing through the heat exchange component to make them maintain the same width for subsequent lamination work. At the same time, the width limiting component also adjusts the wind area of the heat exchange component, so that aluminum foils and plastic films with different widths use different areas of wind energy;

[0019] S4. Preheat the passing aluminum foil and plastic film through the heat exchange component with hot air to make the glue reach a suitable temperature, thereby activating the viscosity of the glue. At the same time, make the aluminum foil and plastic film materials softer. Increase the ductility of the aluminum foil through preheating, so that it can better fit with the plastic film during the lamination process and reduce the delamination phenomenon caused by stress concentration;

[0020] S5. The preheated aluminum foil and plastic film will pass through the heating device for heating and lamination to form an aluminum-plastic film, and the prepared aluminum-plastic film is output through another heat exchange component. When the aluminum-plastic film passes through another heat exchange component, the width of the aluminum-plastic film is re-limited and cut by the width limiting component, and the aluminum-plastic film is cooled with cold air through another heat exchange component to quickly cure and shape the glue, and make the material shrink back to a relatively stable state, reducing thermal stress and preventing the aluminum-plastic film from deforming or warping during subsequent processing or use;

[0021] S6. Rotate the winding device to rotate and wind the aluminum-plastic film output from the heat exchange component, so as to timely store the produced aluminum-plastic film.

[0022] Compared with the prior art, the beneficial effects of the present invention:

[0023] 1. In the aluminum-plastic film production equipment and method, during the laminating stage of the aluminum foil and the film, one of the width limiting components adaptively cuts and adjusts the width of the aluminum foil and the film, so that the excess edge parts can be accurately cut according to the actual production needs, ensuring the accuracy and consistency of the width size of the aluminum-plastic film and meeting the strict requirements of product specifications in different application scenarios; in the winding link after the aluminum-plastic film is pressed, another width limiting component calibrates the neatness of the rolled aluminum-plastic film and cuts the excess edges, so that the aluminum-plastic film always maintains a tight and neat arrangement during the winding process, effectively avoiding undesirable phenomena such as wrinkles and looseness during the winding process;

[0024] Moreover, while adjusting the required width of the aluminum-plastic film, the width limiting component can also synchronously adjust the wind contact area inside the heat exchange component, so that the heat exchange component can flexibly adjust the range and intensity of wind force according to the actual width of the aluminum-plastic film, thereby improving the heat exchange efficiency and effect.

[0025] 2. In the aluminum-plastic film production equipment and method, when the aluminum foil and the film pass through the heat exchange component inside one of the width-limiting components, the heat exchange component can accurately preheat them; using an appropriate preheating temperature can effectively activate the activity of the glue, enhance the adhesion between the glue and the aluminum foil and the film, and thus greatly improve the composite strength of the aluminum-plastic film; at the same time, preheating can also make the materials of the aluminum foil and the film softer, improve their plasticity and tightness of lamination during the lamination process, and further optimize the overall quality of the product;

[0026] When the pressed aluminum-plastic film passes through the heat exchange component inside another width-limiting component, the heat exchange component quickly switches to cooling mode to efficiently cool the aluminum-plastic film; rapid cooling can promote rapid solidification of the glue, stabilize the composite structure of the aluminum-plastic film, and effectively prevent delamination and deformation caused by incomplete solidification of the glue; in addition, cooling can also make the size of the aluminum-plastic film more stable, reduce dimensional deviations caused by thermal expansion and contraction effects, and ensure that the product meets strict requirements on dimensional accuracy.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Example 1: Please refer to Figures 1 - 6As shown, the purpose of this embodiment is to provide an aluminum-plastic film production device, including a top plate 1, a bracket 11 is provided near both ends of the bottom of the top plate 1, an aluminum foil unwinding device 12 is provided near the bottom at one end of the bracket 11, and a film unwinding device 13 is provided near the top at one end of the bracket 11; a glue coating device 14 is provided at one end of the bracket 11 between the aluminum foil unwinding device 12 and the film unwinding device 13, a winding device 15 is provided near the center at the other end of the bracket 11, and a heating device 18 is provided inside the bracket 11;

[0045] The outer walls at both ends of the bracket 11 are provided with width limiting components 17, and a heat exchange component 16 is provided between the two width limiting components 17 and the inside of the bracket 11, wherein one width limiting component 17 is located between the film unwinding device 13 and the glue coating device 14, and the other width limiting component 17 is located at the top of the winding device 15;

[0046] One of the width limiting components 17 is used to align the aluminum foil and the film, and adaptively cut and adjust their widths to ensure the uniformity of the aluminum foil and the film; the other width limiting component 17 is used to calibrate the uniformity of the rolling of the aluminum-plastic film after lamination; while adjusting the required width of the aluminum-plastic film, the width limiting component 17 also adjusts the wind contact area inside the heat exchange component 16; when the aluminum foil and the film pass through the heat exchange component 16 inside one of the width limiting components 17, the heat exchange component 16 preheats the aluminum foil and the film; when the aluminum-plastic film after lamination passes through the heat exchange component 16 inside the other width limiting component 17, the heat exchange component 16 cools the aluminum-plastic film.

[0047] The improvement of this embodiment is that: in the initial stage of laminating the aluminum foil and the film, the width of the two is adaptively cut and adjusted by the width limiting component 17; this precise cutting not only eliminates the redundant edge part, ensures the accuracy of the width size of the aluminum-plastic film, but also enables the product to seamlessly meet the stringent specification requirements in various application scenarios;

[0048] When the aluminum-plastic film is pressed and enters the winding stage, the width limiting component 17 ensures that the aluminum-plastic film always maintains an ideal state of tightness and neatness during the winding process by calibrating the neatness of the rolled aluminum-plastic film and cutting off the redundant edges; this measure effectively avoids quality defects such as wrinkles and looseness, and improves the appearance and overall quality of the product; at the same time, the neat winding state is conducive to subsequent storage, transportation and reprocessing, reducing production stagnation and equipment loss caused by uneven materials, further optimizing the continuity and stability of the production process, and improving production efficiency and economic benefits;

[0049] Moreover, while adjusting the width of the aluminum-plastic film, the width-limiting component 17 can synchronously and precisely regulate the wind contact area inside the heat exchange component 16, enabling the heat exchange component 16 to flexibly and precisely adjust the action range and intensity of the wind according to the real-time width of the aluminum-plastic film. Whether in the preheating or cooling stage, this precisely adapted heat exchange mode greatly improves the efficiency and uniformity of heat transfer, ensuring that the aluminum-plastic film can quickly and stably reach the ideal temperature state during the production process.

[0050] In the preheating stage before the aluminum foil and the film are laminated, when they pass through the heat exchange component 16 inside the width-limiting component 17, the hot air of the heat exchange component 16 blows towards the aluminum foil and the film, activating the glue by raising its preheating temperature, significantly enhancing the intermolecular interaction force of the glue, and thus forming a more firm and tight bonding relationship with the aluminum foil and the film, greatly improving the composite strength of the aluminum-plastic film. At the same time, the preheating process also endows the aluminum foil and the film with better plasticity, enabling them to come into closer and more uniform contact during the lamination process, effectively reducing the generation of internal stress and bubbles, further optimizing the overall quality of the product, and enhancing the barrier performance and durability of the product.

[0051] In the cooling stage after the aluminum-plastic film is laminated, when the product passes through the heat exchange component 16 inside another width-limiting component 17, the heat exchange component 16 blows out cold air, which acts on the aluminum-plastic film to cool it. The cooling process can prompt the glue to cure quickly, timely stabilize the composite structure of the aluminum-plastic film, effectively prevent serious quality problems such as delamination and deformation that may be caused by incomplete curing of the glue, and ensure the structural integrity and stability of the product. In addition, the cooling operation also makes the size of the aluminum-plastic film more stable, precisely controlling the dimensional deviation caused by the thermal expansion and contraction effect, ensuring that the product always meets various strict application requirements in terms of dimensional accuracy, and further enhancing the reliability and applicability of the product.

[0052] First, the specific structure of the heat exchange component 16 is disclosed. The heat exchange component 16 includes a dual-temperature air gun 160. Ventilation pipes 161 are provided at both ends of the dual-temperature air gun 160. The air body conveyed inside the ventilation pipe 161 close to the gluing device 14 is hot air, and the air body conveyed inside the ventilation pipe 161 close to the winding device 15 is cold air.

[0053] Refer to Figure 4 、 Figure 8 And Figure 9 As shown, hot air and cold air are respectively output through the dual-temperature air gun 160. The hot air is conveyed inside the ventilation pipe 161 close to the gluing device 14, and the cold air is conveyed inside the ventilation pipe 161 close to the winding device 15. The aluminum foil and the plastic film passing through the ventilation pipe 161 where the hot air is output are preheated, and the aluminum-plastic film passing through the ventilation pipe 161 where the cold air is output is cooled.

[0054] Among them, the dual-temperature hot air gun 160 has a working principle known to those skilled in the art. There are two independent air ducts and heating / cooling systems inside this hot air gun; one air duct is responsible for generating hot air, heating the air through a heating element (such as an electric heating wire); the other air duct is connected to a refrigeration module, generating cold air through compression refrigeration or semiconductor refrigeration, etc.; at the air outlet, through a special design, the hot air and cold air are mixed and blown out from different outlets respectively, so as to realize the function of blowing hot air and cold air simultaneously;

[0055] Among them, the ventilation pipe 161 includes a conduit 1610, the conduit 1610 is arranged at the output end of the dual-temperature hot air gun 160, the other end of the conduit 1610 is fixedly connected with an air pipe 1611, the conduit 1610 is a multi-fold pipe, the conduit 1610 is arranged inside the bracket 11, and a width-limiting component 17 is arranged on the outer wall of the air pipe 1611, and a plurality of air holes are arranged near the center inside the air pipe 1611;

[0056] Refer to Figure 10 As shown, by dividing the ventilation pipe 161 into two parts, transporting the wind energy through the conduit 1610, and evenly dispersing the wind energy inside the two air pipes 1611 at its end, and outputting the fan outward through the plurality of air holes on the air pipe 1611, so as to preheat and cool the aluminum foil, plastic film and aluminum-plastic film passing between the two air pipes 1611 respectively.

[0057] Secondly, the specific structure of the width-limiting component 17 is disclosed. The width-limiting component 17 includes two struts 170, the two struts 170 are respectively fixedly connected to one end of the bracket 11, near both sides, two sleeves 172 are arranged inside the struts 170; one end of one of the sleeves 172 is fixedly connected with a blade 173, one end of the outer wall of the blade 173 is fixedly connected with the output shaft of a cylinder 171, and the two cylinders 171 are respectively fixedly connected to the upper and lower ends of the struts 170; an air pipe 1611 is arranged between the opposite sleeves 172 inside the two struts 170, and the sleeves 172 and the blades 173 can slide on the outer wall of the air pipe 1611;

[0058] Refer to Figure 8 And Figure 11As shown, the cylinder 171, the sleeve 172 and the air pipe 1611 are supported by the support column 170. The piston rod of the cylinder 171 pushes the blade 173 to move on the outer wall of the air pipe 1611, so that the movement of the blade 173 drives the sleeve 172 to move on the outer wall of the air pipe 1611. By adjusting the distance between the two opposite blades 173, the width of the required aluminum-plastic film can be adaptively adjusted. Moreover, while the sleeve 172 is moving, the number of air holes exposed on the air pipe 1611 is adjusted. The closer the distance between the two blades 173 is, the more the sleeve 172 blocks the air pipe 1611, so that the wind energy is concentrated in the middle of the air pipe 1611, ensuring the wind force for preheating and cooling.

[0059] Embodiment 2: Based on the content provided in Embodiment 1, this embodiment aims to provide a method for an aluminum-plastic film production device. The specific steps are as follows:

[0060] S1. First, place the appropriate aluminum foil and plastic film inside the aluminum foil unwinding device 12 and the film unwinding device 13 respectively. The aluminum foil passes through the coating device 14 through the aluminum foil unwinding device 12 and enters one of the heat exchange components 16. The plastic film also enters one of the heat exchange components 16 through the film unwinding device 13. After passing through the heating device 18, the aluminum foil and the plastic film pass through another heat exchange component 16 and finally wind around the winding device 15.

[0061] S2. Start the aluminum foil unwinding device 12, the film unwinding device 13 and the winding device 15. When the aluminum foil passes through the coating device 14, the surface of the aluminum foil will touch the glue on the coating device 14, so that when the aluminum foil enters the heating device 18, it can adhere to the plastic film.

[0062] S3. The piston rod of the cylinder 171 pushes the blade 173 to move on the outer wall of the air pipe 1611, so that the movement of the blade 173 drives the sleeve 172 to move on the outer wall of the air pipe 1611. By adjusting the distance between the two opposite blades 173, the width of the required aluminum-plastic film can be adaptively adjusted. When the aluminum foil and the plastic film pass between the opposite blades 173, the redundant edge parts are removed by the blades 173, ensuring the accurate width dimension of the aluminum-plastic film and enabling the product to seamlessly meet the strict specification requirements in various application scenarios.

[0063] S4. Also, while the sleeve 172 is moving, the number of exposed pores on the air pipe 1611 is adjusted. The closer the distance between the two blades 173, the more the sleeve 172 blocks the air pipe 1611, so that the wind energy is concentrated in the middle of the air pipe 1611, ensuring the size of the preheating wind force; enabling the air pipe 1611 to flexibly and accurately adjust the action range and intensity of the wind force according to the real-time width of the aluminum foil and the plastic film; greatly improving the efficiency and uniformity of heat transfer, ensuring that the aluminum-plastic film can quickly and stably reach the ideal temperature state during the production process;

[0064] S5. The hot air is conveyed inside the ventilation pipe 161 near the gluing device 14 through the dual-temperature air gun 160, so that the aluminum foil and the plastic film at the ventilation pipe 161 where the hot air is output are preheated, making the glue reach a suitable temperature, thereby activating the viscosity of the glue, significantly enhancing the intermolecular interaction force of the glue, and thus forming a more firm and tight bonding relationship with the aluminum foil and the film, greatly improving the composite strength of the aluminum-plastic film; at the same time, the preheating process also endows the aluminum foil and the film with better plasticity, enabling them to contact each other more closely and evenly during the laminating process, effectively reducing the generation of internal stress and bubbles, further optimizing the overall quality of the product, and enhancing the barrier performance and durability of the product;

[0065] S6. The preheated aluminum foil and plastic film will be heated and laminated through the heating device 18 to form an aluminum-plastic film, and the prepared aluminum-plastic film will be output between the air pipes 1611 near the winding device 15. During the output, the width is cut again through the blade 173 to ensure the accuracy of the width of the output aluminum-plastic film;

[0066] S7. The cold air is conveyed inside the air pipe 161 near the winding device 15 through the dual-temperature air gun 160; the aluminum-plastic film at the air pipe 161 where the cold air is output is cooled; rapid cooling can prompt the glue to cure quickly, stabilize the composite structure of the aluminum-plastic film, and effectively prevent delamination and deformation caused by incomplete curing of the glue; in addition, cooling can also make the size of the aluminum-plastic film more stable, reduce the size deviation caused by the thermal expansion and contraction effect, and ensure that the product meets the strict requirements in terms of dimensional accuracy;

[0067] S8. The winding device 15 rotates to wind up the aluminum-plastic film output from the heat exchange component 16, so as to timely store the produced aluminum-plastic film, avoid the aluminum-plastic film being exposed in the external environment for a long time, and prevent pollutants such as dust and impurities from adhering to its surface, thereby ensuring the cleanliness and appearance quality of the aluminum-plastic film and meeting the high standards required for subsequent processing or use.

[0068] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, which are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.

5. A method for operating the aluminum-plastic film production equipment according to claim 1, characterized in that: The method comprises the following steps: S1. First, suitable aluminum foil and plastic film are placed in the aluminum foil unwinding device (12) and the film unwinding device (13) respectively, wherein the aluminum foil passes through the aluminum foil unwinding device (12) and the glue coating device (14) to enter one of the heat exchange components (16), and the plastic film passes through the film unwinding device (13) and also enters one of the heat exchange components (16). The aluminum foil and the plastic film are passed through the heating device (18) and then through another heat exchange component (16), and finally wound on the winding device (15); S2, starting the aluminum foil unwinding device (12), the film unwinding device (13) and the winding device (15), when the aluminum foil passes through the glue coating device (14), the surface of the aluminum foil will touch the glue liquid on the glue coating device (14), so that the aluminum foil can adhere to the plastic film when entering the interior of the heating device (18); S3, by adjusting the position of the width limiting component (17) on the surface of the heat exchange component (16), the width of the aluminum foil and the plastic film passing through the heat exchange component (16) is limited and cut so that the same width is maintained for subsequent pressing work. At the same time, the width limiting component (17) also adjusts the wind area of ​​the heat exchange component (16) so that aluminum foils and plastic films of different widths use wind energy of different areas; S4, preheating the aluminum foil and plastic film with hot air through the heat exchange component (16) to make the glue reach a suitable temperature, thereby activating the viscosity of the glue and making the aluminum foil and plastic film materials softer. The ductility of the aluminum foil is increased by preheating, so that it can better fit with the plastic film during the lamination process, reducing the delamination phenomenon caused by stress concentration; S5, the preheated aluminum foil and plastic film are heated and pressed together by a heating device (18) to form an aluminum-plastic film, and the prepared aluminum-plastic film is output through another heat exchange component (16). When the aluminum-plastic film passes through another heat exchange component (16), the width of the aluminum-plastic film is limited and cut again by a width limiting component (17), and the aluminum-plastic film is cooled by cold air by another heat exchange component (16), so that the glue is quickly solidified and fixed, and the material is shrunk back to a relatively stable state, so as to reduce thermal stress and prevent the aluminum-plastic film from being deformed or warped during subsequent processing or use; S6. The aluminum-plastic film output from the heat exchange component (16) is rotated and rolled up by the winding device (15), so that the produced aluminum-plastic film can be collected in time.
