Description

Technical Field

[0001] This invention relates to the field of aluminum foil paper coating technology, specifically to an aluminum foil paper coating equipment and coating method. Background Technology

[0002] Foil paper refers to paper made by laminating aluminum foil backing paper with aluminum foil. It is soft and easily deformed, like paper, and does not spring back after deformation. It can be fixed in shape, ensuring light blocking, preventing it from falling off, being opaque, non-polluting, and inexpensive. It is used for moisture-proofing and decorative packaging of high-end cigarettes, candies, and other foods.

[0003] The existing aluminum foil laminating equipment has a complex structure and does not perform secondary lamination and compaction after laminating the aluminum foil, resulting in unsatisfactory lamination quality. Furthermore, the cut edges of the aluminum foil cannot be properly reinforced during cutting, leading to poor flatness at the cut edges and consequently, poor production quality and efficiency in the aluminum foil laminating process. Summary of the Invention

The upper end of the regulating cylinder is provided with a connecting plate. The front end of the lower conveying rollers and the end away from the drive sprocket is provided with a drive motor.

[0010] As a preferred embodiment of the present invention, the film-coated support plate is provided with a matching placement groove corresponding to the lower conveyor roller, and the upper side of the lower conveyor roller is set slightly higher than the upper horizontal plane of the film-coated support plate.

[0015] As a preferred embodiment of the present invention, the limiting support rod passes through the upper limiting sleeve and is slidably connected to the working frame, and a limiting block adapted to the positioning groove is provided at the connection between the working frame and the limiting support rod.

[0016] As a preferred embodiment of the present invention, the lower conveying roller is connected and installed to the middle frame of the work frame through the first bearing seat, and the end of the connecting plate away from the regulating cylinder is fixedly connected to the upper inner side of the work frame.

[0017] In a preferred embodiment of the present invention, the lower conveying roller and the upper conveying roller are arranged correspondingly to each other, and the two sets of lower conveying rollers are connected by a chain through a transmission sprocket.

[0018] A lamination method for an aluminum foil lamination device includes the following steps:

[0019] S1, by laying aluminum foil on the upper side of the coating support plate, the position of the coating roller is adjusted by the drive of the telescopic cylinder, so that the coating roller is in contact with the aluminum foil. The coating roller performs the coating operation on the aluminum foil while the aluminum foil is constantly moving. After the coating roller has coated the aluminum foil, the pressing roller will perform a second pressing on the coated aluminum foil.

[0020] S2, the aluminum foil is fed between two sets of lower and upper conveyor rollers by a puller. The upper conveyor roller is adjusted by a control cylinder to adjust the distance between the upper and lower conveyor rollers to achieve the conveying of the aluminum foil after lamination. The lower conveyor roller is driven by a drive motor to rotate, so as to achieve continuous lamination conveying of the aluminum foil.

[0021] S3, when the coated aluminum foil is wound to a certain quantity, the servo motor drives the pull belt to cut the aluminum foil with scissors, thereby realizing the quantitative winding operation of the aluminum foil.

[0022] This invention enables the coating roller in the coating pressing assembly to perform coating work on passing aluminum foil. Under the action of the telescopic cylinder, the lifting and adjustment of the coating roller can be realized, making the disassembly and replacement of the coating roller simple and convenient, thereby improving the performance of aluminum foil during coating. The pressing spring can achieve top pressure on the pressing roller, thereby improving the pressing effect of aluminum foil after coating and thus achieving high production quality of aluminum foil during coating.

[0023] This invention uses a top-pressure spring in the aluminum foil cutting assembly to press the limiting support rod, thereby positioning the aluminum foil by the pressing and limiting wheel. This allows the cutting scissors to have high positioning accuracy when cutting the aluminum foil, resulting in better flatness and cutting effect.

[0024] This invention enables the feeding of aluminum foil through an aluminum foil feeding assembly. The upper side of the lower conveying roller is set slightly higher than the upper horizontal plane of the laminating plate, which ensures a high degree of smoothness in the feeding of the aluminum foil on the laminating plate. This results in good feeding performance of the aluminum foil during lamination production. At the same time, because the aluminum foil and the laminating plate are in close contact during feeding, the quality of the aluminum foil during lamination production can be effectively improved.

The top pressure spring 309 in the aluminum foil cutting assembly 3 presses the limit support rod 306, so that the pressing limit wheel 310 positions the aluminum foil. This enables the cutting scissors 305 to have high positioning accuracy when cutting the aluminum foil, thus improving the flatness and effect of the aluminum foil during cutting.

[0039] The film-coated mounting plate 101 and the cutting shears 305 are respectively provided with cutting grooves 103. Reinforcing connecting plates 312 are respectively provided on the upper rear left and right sides of the mounting plate 301, and the mounting plate 301 is connected to the work frame 1 through the reinforcing connecting plates 312. A limiting groove is provided on the lower side of the mounting plate 301 corresponding to the snap-fit ​​seat 304. The limiting support rod 306 adopts a "boomerang" structure, with the lower limiting sleeve 308 fixedly connected to the limiting support rod 306, and the upper limiting sleeve 308 slidably connected to the limiting support rod 306. The limiting support rod 306 passes through the upper limiting sleeve 308 and is slidably connected to the work frame 1. A limiting block adapted to the positioning groove 307 is provided at the connection between the work frame 1 and the limiting support rod 306. The cutting groove 103 improves the cutting effect of the cutting scissors 305 when cutting aluminum foil, and the positioning groove 307 limits the positioning support rod 306, making the positioning support rod 306 highly stable during movement and ensuring good pressing and positioning effect of the pressing and positioning wheel 310 on the aluminum foil.

[0040] In this embodiment, reference is made to Figure 1 , 2 As shown in Figure 8, the aluminum foil feeding assembly 4 includes at least two sets of lower conveying rollers 401 and upper conveying rollers 402. First bearing seats 403 are provided at both ends of the lower conveying rollers 401, and second bearing seats 404 are provided at both ends of the upper conveying rollers 402. A drive sprocket 405 is provided at one end of the lower conveying rollers 401. A regulating cylinder 406 is provided on the upper side of the second bearing seat 404, and a connecting plate 407 is provided at the upper end of the regulating cylinder 406. A drive motor 408 is provided on the front lower conveying roller 401, away from the drive sprocket 405. A matching placement groove 102 is provided on the film-coating support plate 101 corresponding to the lower conveying rollers 401. The upper side of the lower conveying rollers 401 is slightly higher than the upper horizontal plane of the film-coating support plate 101. The lower conveyor roller 401 is connected and installed to the middle frame of the work frame 1 via the first bearing seat 403. The end of the connecting plate 407 away from the regulating cylinder 406 is fixedly connected to the upper inner side of the work frame 1. The lower conveyor roller 401 and the upper conveyor roller 402 are arranged vertically and vertically, and the two sets of lower conveyor rollers 401 are connected by a chain drive via a transmission sprocket 405. The aluminum foil paper clamping assembly 4 can clamp and feed the aluminum foil paper. The upper side of the lower conveyor roller 401 is set slightly higher than the upper horizontal plane of the coating support plate 101, which can make the aluminum foil paper conveyed on the coating support plate 101 with high smoothness, thus making the conveying effect of aluminum foil paper during the coating production better. At the same time, since the aluminum foil paper is close to the coating support plate 101 during clamping, the quality of aluminum foil paper during the coating production can be effectively improved.

[0041] In this solution, the aluminum foil laminating equipment operates by laying aluminum foil on the upper side of the laminating support plate 101. The position of the laminating roller 206 is adjusted by the telescopic cylinder 203, allowing the laminating roller 206 to adhere to the aluminum foil. As the aluminum foil continuously moves, the laminating roller 206 performs the laminating operation. After the laminating roller 206 has laminated the aluminum foil, the pressing roller 210 performs a secondary pressing on the laminated aluminum foil. The coating roller 206 in the coating pressing assembly 2 can perform coating work on the aluminum foil paper that passes through it. Under the action of the telescopic cylinder 203, the lifting and adjustment of the coating roller 206 can be realized, making the disassembly and replacement of the coating roller 206 simple and convenient, thereby improving the performance of the aluminum foil paper during coating. The pressing spring 211 can realize the pressing of the pressing roller 210, thereby improving the pressing effect of the aluminum foil paper after lamination, and thus improving the production quality of aluminum foil paper during coating.

[0042] Aluminum foil is fed between two sets of lower conveyor rollers 401 and upper conveyor rollers 402 by a pull conveyor. The upper conveyor roller 402 is adjusted by a regulating cylinder 406 to adjust the distance between the upper conveyor roller 402 and the lower conveyor roller 401, thereby conveying the aluminum foil after lamination. The lower conveyor roller 401 is rotated by a drive motor 408 to achieve continuous lamination conveying of the aluminum foil. The aluminum foil clamping assembly 4 can clamp the aluminum foil. The upper side of the lower conveyor roller 401 is set slightly higher than the upper horizontal plane of the lamination support plate 101, which can make the aluminum foil conveyed on the lamination support plate 101 with high smoothness, thus making the conveying effect of aluminum foil during lamination production good. At the same time, since the aluminum foil is close to the lamination support plate 101 during clamping, the quality of aluminum foil during lamination production can be effectively improved.

[0043] When the coated aluminum foil is wound up to a certain quantity, the servo motor 311 drives the pull belt 303 to cut the aluminum foil with the cutting scissors 305, thereby realizing the quantitative winding operation of the aluminum foil. The top pressure spring 309 in the aluminum foil cutting assembly 3 presses the limiting support rod 306, so that the pressing limiting wheel 310 positions the aluminum foil. This enables the cutting scissors 305 to have high positioning accuracy when cutting the aluminum foil, thus making the flatness and effect of the aluminum foil better during cutting.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
