Description

Technical Field

[0001] This utility model relates to the field of cardboard box lamination technology, and in particular to an automatic wrinkle removal and flattening device for cardboard box lamination. Background Technology

[0002] Carton lamination, also known as "coating," "filming," or "lamination processing," refers to the process of covering a very thin, transparent plastic film (usually BOPP biaxially oriented polypropylene or PET polyester film) onto the printed carton linerboard (i.e., the outermost paper of the carton body) using specialized equipment.

[0003] In the process of laminating cartons, in order to avoid wrinkles, a wrinkle-removing and flattening device is needed to remove and flatten the carton during lamination. However, the existing wrinkle-removing and flattening devices are only for the post-lamination treatment. During the layer-by-layer transportation of the cartons, a lot of dust and other impurities adhere to them and are located below the lamination layer, which can easily lead to the inability to remove and flatten the carton after lamination, thus reducing the lamination effect. Utility Model Content

[0004] This utility model discloses an automatic wrinkle removal and flattening device for carton lamination, which aims to solve the technical problem that existing wrinkle removal and flattening devices only treat the post-lamination processing of cartons. During the layer-by-layer transportation of the carton, a lot of dust and other impurities adhere to it and are located below the lamination layer, which easily leads to the inability to remove wrinkles and flatten the carton after lamination.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An automatic wrinkle removal and flattening device for carton lamination includes an installation ring rail and an adjusting guide rail. Two sliding frames are slidably connected to the adjusting guide rail, and an unfolding plate is fixedly connected to each of the two sliding frames. A second drive motor is fixedly connected to the top of each of the two unfolding plates at the middle position. The output shaft of the second drive motor is fixedly connected to a drive shaft via a coupling. A bidirectional processing mechanism is provided below the drive shaft. The bidirectional processing mechanism includes a shaft frame, which is fixedly connected to the bottom of the drive shaft. A forward and reverse motor is fixedly connected to one side of the shaft frame. The output shaft of the forward and reverse motor is fixedly connected to a flipping shaft via a coupling. One end of the flipping shaft is connected to the inner wall of one side of the shaft frame via a bearing. A flattening roller is fixedly connected to the outer wall facing downwards of the flipping shaft. A hollow frame is fixedly connected to the outer wall facing upwards of the flipping shaft. The top of the hollow frame is provided with bristles, and collection holes are opened between the bristles in the hollow frame.

[0006] In a preferred embodiment, an extension plate is fixedly connected to one side of the shaft frame, and a collection box is fixedly connected to the bottom of the extension plate.

[0007] In a preferred embodiment, a collection pump is fixedly connected to the side of the collection box facing the hollow frame, and a telescopic connecting pipe is fixedly connected to the collection end of the collection pump. One end of the telescopic connecting pipe is inserted into the interior of the hollow frame, and the delivery end of the collection pump is connected to the interior of the collection box through a pipe.

[0008] In a preferred embodiment, the bottom of the unfolding plate located below the second drive motor is fixedly connected to a reinforcing ring rail, and a reinforcing slip ring is slidably connected inside the reinforcing ring rail, the reinforcing slip ring being fixedly connected to the top of the shaft frame.

[0009] In a preferred embodiment, a rotating carriage is slidably connected inside the mounting ring rail, and a mounting plate is fixedly connected to the top of the rotating carriage, with an adjusting guide rail fixedly connected to the bottom of the mounting plate.

[0010] In a preferred embodiment, a middle plate is fixedly connected to the top of the mounting plate, and hydraulic cylinders are fixedly connected to both sides of the middle plate, with the output end of the hydraulic cylinders fixedly connected to one side of an adjacent sliding frame.

[0011] In a preferred embodiment, a motor frame is fixedly connected to the bottom of the mounting ring rail, and a drive motor is fixedly connected to the motor frame. The output shaft of the drive motor is fixedly connected to a rotating shaft via a coupling, and the top of the rotating shaft is fixedly connected to the bottom of the mounting plate.

[0012] As can be seen from the above, the automatic wrinkle removal and flattening device for carton lamination provided by this utility model has the technical effect of improving the wrinkle removal and flattening operation. Before the wrinkle removal and flattening operation, the forward and reverse motor is started. The forward and reverse motor drives the hollow frame to rotate downward, so that the bristles contact the lamination area of ​​the carton. Then, the drive motor is started to drive the bristles to rotate and clean the carton. The collection pump is turned on and the impurities attached to the carton are collected through the collection hole. At the same time, the hydraulic cylinder drives the bristles to move, realizing all-round cleaning of the top of the carton, ensuring that after lamination, the bottom of the lamination layer will not have wrinkles due to the presence of impurities.

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

[0019] The automatic wrinkle removal and flattening device for carton lamination disclosed in this utility model is mainly used in scenarios where existing wrinkle removal and flattening devices are only used for processing after carton lamination. During the process of conveying the carton layer by layer, a lot of dust and other impurities are attached to it and located below the lamination layer, which can easily lead to the inability to remove wrinkles and flatten the carton after lamination.

[0020] Reference Figures 1-4 An automatic wrinkle removal and flattening device for carton lamination includes an installation ring rail 1 and an adjusting guide rail 10. Two sliding frames 13 are slidably connected to the adjusting guide rail 10, and each sliding frame 13 is fixedly connected to an unfolding plate 9. A second drive motor 15 is fixedly connected to the top of each unfolding plate 9 at its middle position. The output shaft of the second drive motor 15 is fixedly connected to a drive shaft 16 via a coupling. A bidirectional processing mechanism 4 is located below the drive shaft 16. The bidirectional processing mechanism 4 includes a shaft bracket 401, and the shaft bracket 401 is fixedly connected to the drive shaft 16. At the bottom, a forward and reverse motor 402 is fixedly connected to one side of the shaft frame 401. The output shaft of the forward and reverse motor 402 is fixedly connected to a flip shaft 405 through a coupling. One end of the flip shaft 405 is connected to the inner wall of one side of the shaft frame 401 through a bearing. A flattening roller 407 is fixedly connected to the outer wall of the flip shaft 405 facing downward. A hollow frame 409 is fixedly connected to the outer wall of the flip shaft 405 facing upward. Brushes 408 are provided on the top of the hollow frame 409. Collection holes 406 are opened between the brushes 408 in the hollow frame 409.

[0021] In specific application scenarios, before performing wrinkle removal and flattening operations, the forward and reverse motor 402 is started. The forward and reverse motor 402 drives the hollow frame 409 to rotate downwards, so that the bristles 408 come into contact with the carton's film-covered area. Then, the drive motor 15 is started to drive the bristles 408 to rotate and clean the carton. The collection pump 403 is turned on, and the impurities attached to the carton are collected through the collection hole 406. At the same time, the hydraulic cylinder 6 drives the bristles 408 to move, achieving all-round cleaning of the top of the carton, ensuring that after film-covering, no wrinkles will appear under the film layer due to the presence of impurities.

[0022] Specifically, after the lamination is completed, the forward and reverse motor 402 drives the flattening roller 407 to remove wrinkles and flatten the upper part of the lamination layer, thereby achieving treatment on both the upper and lower sides of the carton lamination layer, ensuring that the carton is wrinkle-free and has high flatness after lamination.

[0023] Reference Figures 1-3 In a preferred embodiment, an extension plate 8 is fixedly connected to one side of the shaft frame 401, and a collection box 7 is fixedly connected to the bottom of the extension plate 8. A collection pump 403 is fixedly connected to the side of the collection box 7 facing the hollow frame 409, and a telescopic connecting pipe 404 is fixedly connected to the collection end of the collection pump 403. One end of the telescopic connecting pipe 404 is inserted into the interior of the hollow frame 409, and the delivery end of the collection pump 403 is connected to the interior of the collection box 7 through a pipe.

[0024] Reference Figure 3 In a preferred embodiment, the bottom of the unfolding plate 9 located below the drive motor 2 15 is fixedly connected to a reinforcing ring rail 17, and a reinforcing slip ring 18 is slidably connected inside the reinforcing ring rail 17. The reinforcing slip ring 18 is fixedly connected to the top of the shaft frame 401.

[0026] Reference Figure 1 and Figure 2 In a preferred embodiment, an intermediate plate 14 is fixedly connected to the top of the mounting plate 5, and hydraulic cylinders 6 are fixedly connected to both sides of the intermediate plate 14. The output end of the hydraulic cylinder 6 is fixedly connected to one side of the adjacent sliding frame 13.

[0027] Reference Figure 1 and Figure 2 In a preferred embodiment, a motor frame 11 is fixedly connected to the bottom of the mounting ring rail 1, and a drive motor 12 is fixedly connected to the motor frame 11. The output shaft of the drive motor 12 is fixedly connected to a rotating shaft 3 via a coupling, and the top of the rotating shaft 3 is fixedly connected to the bottom of the mounting plate 5.

[0028] Working principle: During use, the carton is conveyed to the installation ring rail 1. The drive motor 12 is started, which drives the two shaft frames 401 to rotate above the carton. The forward and reverse motor 402 is started, which drives the hollow frame 409 to rotate downward, so that the brush bristles 408 contact the carton's film-coated area. Then, the drive motor 2 is started, which drives the brush bristles 408 to rotate and clean the carton. The collection pump 403 is turned on, and the impurities attached to the carton are collected through the collection hole 406. At the same time, the hydraulic cylinder 6 drives the brush bristles 408 to move, achieving all-round cleaning of the top of the carton. After cleaning, the forward and reverse motor 402 drives the hollow frame 409 to reset, and the drive motor 12 drives the shaft frame 401 to reset. Then, the film-coating operation begins. After film-coating is completed, the forward and reverse motor 402 drives the flattening roller 407 to remove wrinkles and flatten the top of the film layer, thereby achieving treatment of both the top and bottom surfaces of the carton's film layer, and the operation ends.
