Description

Technical Field

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

[0002] As a composite material made by cleverly stacking aluminum foil and plastic film, aluminum-plastic film has significant advantages. Its aluminum foil layer has excellent insulation and sealing properties, which can effectively block heat transfer and prevent gas penetration, creating a stable environment inside. The addition of plastic film is the finishing touch, which allows aluminum-plastic film to get rid of the rigidity of pure aluminum foil, have good flexibility, and be lighter in texture. Both portability and ease of use are greatly improved, and it can be flexibly adapted to a variety of packaging scenarios; in addition, aluminum-plastic film is easy to cut, trim and shape, and can be processed into products of different shapes and specifications. Therefore, aluminum-plastic film is an ideal packaging material for lithium-ion batteries.

[0003] In the current industrial production process of aluminum-plastic film, the conventional practice is to gather key raw materials in advance, such as aluminum foil, polyethylene terephthalate (PET) film or biaxially oriented polypropylene (BOPP) film, and suitable adhesives. Then, the adhesive is evenly applied to the surface of the PET or BOPP film using precision coating equipment, laying a solid foundation for the subsequent composite process. Finally, with the help of professional lamination machinery, the aluminum foil is tightly attached to the PET or BOPP film coated with adhesive, so that the two are strongly bonded by the adhesive and seamlessly connected to form an aluminum-plastic film product.

[0004] However, in the pressing process of the existing aluminum-plastic film production equipment, on the one hand, there is a lack of consideration for the preheating process, which makes it inconvenient to preheat the aluminum-plastic film raw materials before the pressing operation, so as to activate the adhesive performance and optimize the material fit; on the other hand, after the pressing is completed, it is inconvenient to dissipate the heat of the finished aluminum-plastic film in time, which may easily cause the glue to be in a semi-cured state for a long time, thereby reducing the bonding strength of the aluminum-plastic film; in addition, in the production process of aluminum-plastic film, due to the diversification of market demand, the width requirements of the finished aluminum-plastic film are different, and it is usually necessary to cut it after the pressing is completed. It is inconvenient to directly adjust the width of the aluminum-plastic film as needed during the production process, which may easily increase production costs and time consumption, and is inefficient, and it is difficult to meet the needs 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 object of the present invention is to provide an aluminum-plastic film production device and method to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned object, one of the objects of the present invention is to provide an aluminum-plastic film production device, comprising a top plate, wherein the bottom of the top plate is provided with brackets near both ends, one end of the bracket is provided with an aluminum foil unwinding device near the bottom, and one end of the bracket is provided with a film unwinding device near the top; one end of the bracket is provided with a glue coating device between the aluminum foil unwinding device and the film unwinding device, and the other end of the bracket is provided with a winding device near the center, and a heating device is provided inside the bracket; The outer walls at both ends of the bracket are provided with width limiting components, and a heat exchange component is provided between the two width limiting components and the inside of the bracket, one of the width limiting components is located between the film unwinding device and the glue coating device, and the other width limiting component is located on the top of the winding device; One of the width limiting components is used to align the aluminum foil and the film, and to adaptively cut and adjust their widths to ensure the uniformity of the aluminum foil and the film; the other width limiting component 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 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.

[0008] As a further improvement of the present technical solution, the heat exchange component includes a dual-temperature air gun, and ventilation ducts are provided at the ends of both sides of the dual-temperature air gun. The air transported inside the ventilation duct near the gluing device is hot air, and the air transported inside the ventilation duct near the winding device is cold air.

[0009] As a further improvement of the present technical solution, the ventilation duct includes a conduit, which is arranged at the output end of the dual-temperature air gun, and the other end of the conduit is fixedly connected to an air pipe. The conduit is a multi-fold pipe, and the conduit is arranged inside the bracket. A limited width component is provided on the outer wall of the air pipe, and a plurality of air holes are provided near the center of the air pipe.

[0010] As a further improvement of the technical solution, the width-limiting component includes two pillars, and the two pillars are respectively fixedly connected to one end of the bracket near two sides, and two sleeves are provided inside the pillars.

[0011] As a further improvement of the technical solution, a blade is fixedly connected to one end of the sleeve, a cylinder output shaft is fixedly connected to the outer wall of one end of the blade, and the two cylinders are fixedly connected to the upper and lower ends of the pillar respectively.

[0012] As a further improvement of the technical solution, an air tube is provided between the insides of the sleeves opposite to each other inside the two pillars, and the sleeve and the blade can slide on the outer wall of the air tube.

[0013] The second object of the present invention is to provide a method for operating the aluminum-plastic film production equipment described above, comprising the following method steps: S1. First, suitable aluminum foil and plastic film are placed in the aluminum foil unwinding device and the film unwinding device respectively, wherein the aluminum foil passes through the aluminum foil unwinding device and the glue coating device to enter one of the heat exchange components, and the plastic film passes through the film unwinding device and also enters one of the heat exchange components, and the aluminum foil and the plastic film pass through the heating device and then pass through another heat exchange component, and finally are wound on the winding device; S2, start the aluminum foil unwinding device, the film unwinding device and the winding device. When the aluminum foil passes through the glue coating device, the surface of the aluminum foil will touch the glue on the glue coating device, so that the aluminum foil can stick to the plastic film when entering the heating device; S3. By adjusting the position of the width limiting component on the surface of the heat exchange component, the width of the aluminum foil and the plastic film passing through the heat exchange component is limited and cut so that the same width is maintained for subsequent pressing 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 of different widths use wind energy of different areas; S4. Preheat the aluminum foil and plastic film with hot air through the heat exchange component 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 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 limited and cut again by a width limiting component, and the aluminum-plastic film is cooled by cold air by another heat exchange component to quickly solidify the glue and shrink the material back to a relatively stable state, thereby reducing thermal stress and preventing 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 is rotated and rolled up by the winding device, so that the produced aluminum-plastic film is collected in time.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 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; 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.

[0015] 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; 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.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example 1: Please refer to Figure 1-Figure 6 As 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; 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; 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.

[0020] 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; 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; Moreover, while adjusting the width of the aluminum-plastic film, the width limiting component 17 can simultaneously and accurately adjust the wind contact area inside the heat exchange component 16, so that the heat exchange component 16 can flexibly and accurately adjust the range and intensity of the wind force 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; In the preheating stage before the aluminum foil and the film are bonded together, 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 toward the aluminum foil and the film, so that the preheating temperature stimulates the activity of the glue, and the interaction force between the glue molecules is significantly enhanced, thereby forming a more solid and tight bonding relationship between the aluminum foil and the film, greatly improving the composite strength of the aluminum-plastic film; at the same time, the preheating process also gives the aluminum foil and the film better plasticity, so that they can contact each other more closely and evenly during the bonding 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; During the cooling stage after the aluminum-plastic film is pressed together, when the product passes through the heat exchange component 16 inside another width-limiting component 17, the heat exchange component 16 will blow out cold air to act on the aluminum-plastic film to cool it. The cooling process can prompt the glue to solidify quickly and stabilize the composite structure of the aluminum-plastic film in time, effectively preventing serious quality problems such as delamination and deformation that may be caused by incomplete curing of the glue, thereby ensuring the structural integrity and stability of the product. In addition, the cooling operation also makes the size of the aluminum-plastic film more stable, accurately controls the dimensional deviation caused by the thermal expansion and contraction effect, ensures that the product always meets various strict application requirements in terms of dimensional accuracy, and further improves the reliability and applicability of the product.

[0021] 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 the ends of both sides of the dual-temperature air gun 160. The air body transported inside the ventilation pipe 161 close to the glue coating device 14 is hot air, and the air body transported inside the ventilation pipe 161 close to the winding device 15 is cold air. See also Figure 4 , Figure 8 and Fig. 9 As shown, hot air and cold air are outputted respectively through the dual-temperature air gun 160, wherein the hot air is transported inside the ventilation pipe 161 near the glue coating device 14, and the cold air is transported inside the ventilation pipe 161 near the winding device 15; so that 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; The working principle of the dual-temperature air gun 160 is known to those skilled in the art. The air gun is internally designed with two independent air ducts and heating / cooling systems. One air duct is responsible for generating hot air, which heats the air through a heating element (such as a heating wire). The other air duct is connected to a cooling module, which generates cold air through compressor cooling or semiconductor cooling. At the air outlet, the hot air and the cold air are mixed through a special design, and are blown out from different outlets, thereby achieving the function of blowing out hot air and cold air at the same time. The ventilation pipe 161 includes a conduit 1610, which is arranged at the output end of the dual-temperature air gun 160, and the other end of the conduit 1610 is fixedly connected to an air pipe 1611, and the conduit 1610 is a multi-fold pipe, and the conduit 1610 is arranged inside the bracket 11, and a limited width component 17 is arranged on the outer wall of the air pipe 1611, and a plurality of air holes are arranged near the center of the air pipe 1611; See also Fig.10As shown, by dividing the ventilation pipe 161 into two parts, the wind energy is transported through the duct 1610 and evenly dispersed inside the two air pipes 1611 at its ends, and the fan is output to the outside through multiple air holes on the air pipe 1611, thereby preheating and cooling the aluminum foil, plastic film and aluminum-plastic film passing through the two air pipes 1611 respectively.

[0022] Secondly, the specific structure of the width limiting component 17 is disclosed. The width limiting component 17 includes two pillars 170, and the two pillars 170 are respectively fixedly connected to one end of the bracket 11. Near the two sides, two sleeves 172 are arranged inside the pillars 170; one end of the sleeve 172 is fixedly connected to a blade 173, and the outer wall of one end of the blade 173 is fixedly connected to the output shaft of the cylinder 171, and the two cylinders 171 are respectively fixedly connected to the upper and lower ends of the pillar 170; an air pipe 1611 is arranged between the inner parts of the sleeves 172 opposite to each other in the two pillars 170, and the sleeve 172 and the blade 173 can slide on the outer wall of the air pipe 1611; See also Figure 8 and Fig.11 As shown, the cylinder 171, the sleeve 172 and the air pipe 1611 are supported by the pillar 170, and the blade 173 is pushed to move on the outer wall of the air pipe 1611 by the piston rod of the cylinder 171, 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 required width of the aluminum-plastic film is adaptively adjusted; and when the sleeve 172 moves, the number of air holes exposed on the air pipe 1611 is adjusted, and 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 wind force for preheating and cooling.

[0023] Embodiment 2: This embodiment is based on the content provided in Embodiment 1, and its purpose is to provide a method for producing aluminum-plastic film equipment, and the specific steps are as follows: 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 to enter one of the heat exchange components 16, and the aluminum foil and the plastic film pass through the heating device 18 and then pass through another heat exchange component 16, and finally are wound on the winding device 15; 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 glue coating device 14, the surface of the aluminum foil will touch the glue on the glue coating device 14, so that the aluminum foil can stick to the plastic film when entering the heating device 18; 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; the spacing between the two opposite blades 173 is adjusted to adaptively adjust the required width of the aluminum-plastic film; when the aluminum foil and the plastic film pass between the opposite blades 173, the blades 173 eliminate the excess edge parts, thereby ensuring the accuracy of the width of the aluminum-plastic film and enabling the product to seamlessly meet the stringent specifications in various application scenarios; S4. In addition, 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 preheating wind force; the air pipe 1611 can flexibly and accurately adjust the scope and intensity of the wind force according to the real-time width of the aluminum foil and the plastic film; the efficiency and uniformity of heat transfer are greatly improved, ensuring that the aluminum-plastic film can quickly and stably reach the ideal temperature state during the production process; S5. The hot air is delivered to the inside of the ventilation pipe 161 near the glue coating device 14 by the dual-temperature air gun 160, so that the aluminum foil and the plastic film passing through the ventilation pipe 161 where the hot air is output are preheated, so that the glue reaches a suitable temperature, thereby activating the viscosity of the glue, and significantly enhancing the interaction force between the glue molecules, thereby forming a more solid 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 gives the aluminum foil and the film better plasticity, so that they can 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; S6, the preheated aluminum foil and plastic film are heated and pressed by the heating device 18 to form an aluminum-plastic film, and the prepared aluminum-plastic film is output through the air pipe 1611 close to the winding device 15, and while outputting, the width is cut again by the blade 173 to ensure the accuracy of the width of the output aluminum-plastic film; S7, cold air is delivered to the inside of the air pipe 1611 near the winding device 15 through the dual-temperature air gun 160; the aluminum-plastic film passing through the air pipe 1611 outputting the cold air is cooled; the rapid cooling can promote the 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 the size deviation caused by the thermal expansion and contraction effect, and ensure that the product meets strict requirements in terms of dimensional accuracy; S8. 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, avoiding the aluminum-plastic film from being exposed to the external environment for a long time, preventing dust, impurities and other pollutants from adhering to its surface, thereby ensuring the cleanliness and appearance quality of the aluminum-plastic film and meeting the high standards for subsequent processing or use.

The aluminum foil and the plastic film are passed through the heating device (18) and then through the other heat exchange component (16), and finally are 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 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 the plastic film with hot air through the heat exchange component (16) so that the glue reaches a suitable temperature, thereby activating the viscosity of the glue and making the aluminum foil and the plastic film material 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, thereby reducing the delamination phenomenon caused by stress concentration; S5, the preheated aluminum foil and the 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 rolling device (15), so that the produced aluminum-plastic film can be collected in time.
