Description

Technical Field

[0001] This application relates to the field of materials processing equipment technology, and in particular to an apparatus for rapid double-sided coating of aluminum foil. Background Technology

[0002] Aluminum foil is a hot stamping material made by directly rolling metallic aluminum into thin sheets. Aluminum is soft, ductile, and has a silvery-white luster. Due to its excellent properties, aluminum foil is widely used in food, beverages, cigarettes, pharmaceuticals, photographic plates, and household daily necessities. Various coatings can be applied to the surface of aluminum foil to enhance its performance and adapt to applications in various industries.

[0003] In existing technologies, coatings are typically sprayed or dripped directly onto the surface of a coating roller, lacking a premixing step, which leads to unstable coating quality. Therefore, there is an urgent need for a device that achieves uniform coating distribution and simultaneous double-sided coating through a rolling process. Summary of the Invention

[0004] The purpose of this application is to provide an apparatus for rapid double-sided coating of aluminum foil in order to solve the above-mentioned problems. The apparatus adopts a pre-coating structure, which allows the coating to be evenly applied to the coating roller, and then the coating roller contacts the aluminum foil to apply the coating, so that the coating is evenly distributed.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] An apparatus for rapid double-sided coating of aluminum foil includes: a frame, a first conveyor roller, a second conveyor roller, a third conveyor roller, a fourth conveyor roller, and aluminum foil. The first, second, third, and fourth conveyor rollers all extend axially along a first direction, and the first and second conveyor rollers, as well as the third and fourth conveyor rollers, are spaced apart along a second direction. Simultaneously, the first and fourth conveyor rollers, as well as the second and third conveyor rollers, are spaced apart along a third direction. Both ends of the first, second, third, and fourth conveyor rollers are rotatably connected to the frame. The aluminum foil is wound around the first conveying roller, the second conveying roller, the third conveying roller, and the fourth conveying roller. The frame is also equipped with two sets of coating components that can coat both sides of the aluminum foil. The coating components include: a coating roller, a transfer roller, a feed pipe, and nozzles. The coating roller and the transfer roller are arranged side by side along a third direction so that they can roll against each other. The coating roller and the transfer roller are connected to a drive component that can drive them to rotate synchronously. The feed pipe is located above the transfer roller and extends along the first direction. The feed pipe is equipped with multiple nozzles facing the transfer roller downward so that the coating can be dripped along the axial direction of the transfer roller.

[0007] Furthermore, the two sets of coating components are distributed between the first and second conveying rollers and the third and fourth conveying rollers.

[0008] Furthermore, the drive assembly includes gears, a height adjustment frame, and a motor. Gears are provided on the same side ends of the coating roller and the transfer roller, and they mesh with each other. The height adjustment frame is distributed at both ends of the coating roller and the transfer roller, and the coating roller and the transfer roller are rotatably connected to the height adjustment frame. The height adjustment frame can be raised and lowered. The motor is fixedly installed on the height adjustment frame, and its output shaft is connected to the coating roller.

[0009] Furthermore, it also includes: a slide, a fixing block, and studs. The slide extends along a third direction and is fixedly installed on both sides of the height adjustment frame. The frame is provided with a clearance opening for the height adjustment frame to be raised and lowered. The slide and the clearance opening are slidably engaged. The fixing block is arranged above and below the height adjustment frame and is fixedly connected to the frame. The fixing block is screwed with studs that can abut against the height adjustment frame.

[0010] Furthermore, multiple studs are screwed onto the fixing block.

[0011] Compared to existing technologies, this application uses a transfer roller. The nozzle first sprays the paint onto the transfer roller, then the transfer roller contacts the coating roller, so that the paint is evenly spread onto the coating roller through extrusion. Then the coating roller contacts the aluminum foil to apply the paint, so that the paint is evenly distributed. Attached Figure Description

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0019] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0020] like Figure 1-3 As shown, an apparatus for rapid double-sided coating of aluminum foil includes: a frame 1, a first conveying roller 2, a second conveying roller 3, a third conveying roller 4, a fourth conveying roller 5, and an aluminum foil 16. The first conveying roller 2, the second conveying roller 3, the third conveying roller 4, and the fourth conveying roller 5 all extend axially along a first direction Y. The first conveying roller 2 and the second conveying roller 3, as well as the third conveying roller 4 and the fourth conveying roller 5, are spaced apart along a second direction X. Simultaneously, the first conveying roller 2 and the fourth conveying roller 5, as well as the second conveying roller 3 and the third conveying roller 4, are spaced apart along a third direction Z. The two ends of the first conveying roller 2, the second conveying roller 3, the third conveying roller 4, and the fourth conveying roller 5 rotate relative to the frame 1. The aluminum foil 16 is wound around the first conveying roller 2, the second conveying roller 3, the third conveying roller 4, and the fourth conveying roller 5. The frame 1 is also equipped with two sets of coating components that can coat both sides of the aluminum foil 16. The coating components include: a coating roller 6, a transfer roller 7, a feed pipe 9, and a nozzle 10. The coating roller 6 and the transfer roller 7 are arranged side by side along the third direction Z so that they can roll against each other. The coating roller 6 and the transfer roller 7 are connected to a drive component that can drive them to rotate synchronously. The feed pipe 9 is located above the transfer roller 7 and extends along the first direction Y. The feed pipe 9 is equipped with a plurality of nozzles 10 facing the transfer roller 7 downward so as to drip coating along the axial direction of the transfer roller 7.

[0021] Specifically, the frame 1 mainly supports the rotation of the rollers and is not limited to the shape shown in the attached figure. The first conveying roller 2, the second conveying roller 3, the third conveying roller 4, and the fourth conveying roller 5 are connected to a driver, such as a motor, which drives the aluminum foil 16 to be conveyed. The aluminum foil 16 is first conveyed horizontally, then guided to be conveyed vertically, and then conveyed horizontally in the reverse direction, so that both sides are facing upwards, so that the coating component can coat it. The paint is pumped into the conveying pipe 9 through a pumping device connected to the conveying pipe 9. The pumping device is existing technology. Then it is sprayed onto the transfer roller 7 through the nozzle 10. The transfer roller 7 then contacts the coating roller 6, so that the paint is evenly applied to the coating roller 6 through extrusion. Then the coating roller 6 contacts the aluminum foil 16 to coat the paint, so that the paint is evenly distributed.

[0022] Furthermore, two sets of coating components are distributed between the first conveying roller 2 and the second conveying roller 3, as well as the third conveying roller 4 and the fourth conveying roller 5, so as to be able to apply the coating to both sides of the aluminum foil 16.

[0023] Furthermore, the drive assembly includes gears 8, a height adjustment frame 11, and a motor 13. Gears 8 are provided on the same side ends of the coating roller 6 and the transfer roller 7 and mesh with each other. The height adjustment frame 11 is distributed at both ends of the coating roller 6 and the transfer roller 7, and the coating roller 6 and the transfer roller 7 are rotatably connected to the height adjustment frame 11. The height adjustment frame 11 can be raised and lowered along Z. The motor 13 is fixedly installed on the height adjustment frame 11, and its output shaft is connected to the coating roller 6.

[0024] Specifically, when one of the coating roller 6 and the transfer roller 7 is driven by the meshing gear 8, the other gear 8 rotates synchronously, thereby extruding and rolling the coating material.

[0025] Furthermore, it also includes: a slide 12, a fixing block 14, and a stud 15. The slide 12 extends along the third direction Z and is fixedly installed on both sides of the height adjustment frame 11. The frame 1 is provided with a clearance opening for the height adjustment frame 11 to be raised and lowered. The slide 12 slides and the clearance opening. The fixing block 14 is arranged above and below the height adjustment frame 11 and is fixedly connected to the frame 1. The fixing block 14 is screwed with a stud 15 that can abut against the height adjustment frame 11.

[0026] Specifically, by screwing the studs 15 on the two fixing blocks 14, the studs 15 are raised and lowered, thereby adjusting the height of the height adjustment frame 11 to adapt to the thickness of the aluminum foil 16. When the height adjustment frame 11 is raised and lowered, the slide 12 slides on the clearance opening to make the height adjustment frame 11 rise and fall stably.

[0027] Furthermore, multiple studs 15 are screwed onto the fixing block 14 to stably support the height adjustment frame 11.

[0028] In the above structure, the aluminum foil is first placed on the first conveying roller 2, then passes around the second conveying roller 3 and the third conveying roller 4, and then placed on the fourth conveying roller 5 to achieve conveying. When passing the coating roller 6, the paint is pumped into the conveying pipe 9 and then drips from the nozzle 10. It first drips onto the transfer roller 7. The rotating transfer roller 7 and coating roller 6 can make the paint uniform. Then the uniform paint is applied from the coating roller 6 to the aluminum foil 16. The aluminum foil 16, which passes around the second conveying roller 3 and the third conveying roller 4, is flipped over. Another set of coating components applies the paint to the other side of the aluminum foil 16, thereby achieving fast double-sided coating and uniform coating. When it is necessary to adjust the height of the coating roller 6 and the transfer roller 7, the studs 15 on the two fixing blocks 14 are turned up and down to adjust the height of the height adjustment frame 11.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application. Various changes and modifications can be made to this application without departing from the spirit and scope thereof, and all such changes and modifications fall within the scope of this application as claimed.
