Description

Technical Field

[0001] The utility model relates to the technical field of laminated paper production, and more specifically, to a flattening device for laminated paper. Background Art

[0002] A laminated paper bag is a paper bag with a layer of plastic film (usually polyethylene) coated on its surface. This kind of paper bag has certain waterproof, oil-proof and moisture-proof properties, enabling the items inside the paper bag to be better protected. Laminated paper bags are widely used in fields such as food packaging (such as bread bags, pastry bags), clothing packaging, and gift packaging. The laminating process can enhance the strength and durability of the paper bag, and at the same time make the surface of the paper bag smoother and the printing effect better. In addition, laminated paper bags are relatively environmentally friendly and can replace some plastic products to a certain extent, reducing environmental pollution.

[0003] The patent with the Chinese patent publication number CN219044144U discloses an upper paper mechanism for laminated paper production, including a substrate. Through holes are symmetrically formed in the upper and lower side walls on one side of the substrate in the front and back directions, and mounting bolts are fixedly installed in the through holes. On the other side of the top wall of the substrate, connecting columns are symmetrically fixedly connected in the front and back directions. On the other side of the bottom wall of the substrate, a mounting seat is fixedly connected. The top walls of the two mounting bolts are fixedly connected to the same first mounting plate, and the height of the first mounting plate can be adjusted by adjusting the heights of the two mounting bolts. By setting an adjustable guiding upper paper structure for laminated paper production, during the actual upper paper work for laminated paper production, adaptive guiding upper paper auxiliary work for laminated paper production can be carried out, and the actual upper paper work efficiency for laminated paper production is relatively high; by setting two flattening wheels, flattening operations are performed on the laminated paper to avoid wrinkles on the surface, improving the flatness and meeting the flatness standard, which brings convenience.

[0004] However, the above-mentioned existing technical solutions have the following defects: they cannot effectively and quickly adjust according to the thickness of the laminated paper. When flattening laminated paper with different thicknesses, it is inconvenient to adjust the distance between the two flattening wheels, resulting in poor use effects of the device.

[0005] Therefore, it is necessary to provide a flattening device for laminated paper to solve the above problems. Summary of the Utility Model

[0006] The utility model provides a flattening device for laminated paper, which can improve the problem that the distance between the flattening wheels is not easy to adjust in the related art.

[0027] A laminated paper bag is a paper bag with a layer of plastic film (usually polyethylene) coated on its surface. This kind of paper bag has certain waterproof, oil-proof, and moisture-proof properties, enabling the items inside the paper bag to be better protected. Laminated paper bags are widely used in food packaging (such as bread bags, pastry bags), clothing packaging, gift packaging, and other fields. The lamination process can enhance the strength and durability of the paper bag, and at the same time, make the surface of the paper bag smoother and the printing effect better. In addition, laminated paper bags are relatively environmentally friendly and can replace some plastic products to a certain extent, reducing environmental pollution.

[0028] The patent with the Chinese patent publication number CN219044144U discloses an upper paper feeding mechanism for the production of laminated paper, including a substrate. Through holes are symmetrically arranged in the front and back between the upper and lower side walls on one side of the substrate, and mounting bolts are fixedly installed in the through holes. Connecting columns are symmetrically fixedly connected to the other side of the top wall of the substrate in the front and back, and a mounting seat is fixedly connected to the other side of the bottom wall of the substrate. The top walls of the two mounting bolts are fixedly connected to the same first mounting plate, and the height of the first mounting plate can be adjusted by adjusting the height of the two mounting bolts. In the present utility model, by providing an adjustable guiding and upper paper feeding structure for the production of laminated paper, when actually performing the upper paper feeding work for the production of laminated paper, adaptive guiding and upper paper feeding assistance work for the production of laminated paper can be carried out, and the actual upper paper feeding work efficiency for the production of laminated paper is relatively high; by providing two flattening wheels, flattening operations are performed on the laminated paper to avoid wrinkles on the surface, improving the flatness, and the flatness meets the standard, which brings convenience.

[0029] However, the above-mentioned existing technical solutions have the following defects: it is not possible to effectively and quickly adjust according to the thickness of the laminated paper. When flattening laminated papers with different thicknesses, it is inconvenient to adjust the distance between the two flattening wheels, resulting in poor use effect of the device.

[0030] Therefore, it is necessary to provide a laminated paper flattening device to solve the above problems.

[0031] Based on this, the problem of difficult adjustment of the distance between the flattening wheels in the related art can be improved.

[0032] Please refer to Figure 1 and Figure 2 , a laminated paper flattening device, including a frame 1, a flattening mechanism 2 and a flattening component 3. The flattening mechanism 2 includes an adjustment component 21 and a driving component 22.

[0033] With such a setting, the flattening mechanism 2 is used for flattening the laminated paper, the adjustment component 21 is used for adjusting the distance between the flattening rollers, which is suitable for laminated papers with different thicknesses, the flattening component 3 is used for further enhancing the flattening effect of the laminated paper after the flattening operation, and the driving component 22 is used for driving the adjustment component 21.

[0034] Optionally, in some embodiments, please refer to Figure 2, the adjusting assembly 21 includes a first flattening roller 211, a slider 212 and a first support plate 213. The first support plate 213 is arranged on the frame 1. A chute 8 is formed on the first support plate 213. The slider 212 is slidably connected to the first support plate 213 through the chute 8. The first flattening roller 211 is arranged on the slider 212. The driving member 22 includes a hydraulic telescopic rod 221 and a hinge member 222. The hydraulic telescopic rod 221 is connected to the first support plate 213. A hinge member 222 is arranged on the output shaft of the hydraulic telescopic rod 221. The hinge member 222 is hinged to the slider 212. The flattening assembly 3 includes a second support plate 31 and a hydraulic cylinder 32. The second support plate 31 is arranged on the frame 1. The hydraulic cylinder 32 is arranged on the second support plate 31. A flattening plate 33 is arranged on the output shaft of the hydraulic cylinder 32. A fillet 7 is arranged on the side of the flattening plate 33 close to the frame 1. A second flattening roller 5 is further arranged on the first support plate 213. The second flattening roller 5 is located below the first flattening roller 211. A driving motor 4 is further arranged on the frame 1. The driving motor 4 is key-connected to the second flattening roller 5. A transition roller 6 is further arranged on the frame 1.

[0035] With such an arrangement, when using the film-coated paper flattening device, first, according to the thickness of the film-coated paper, the hydraulic telescopic rod 221 is adjusted. The hinge member 222 on the hydraulic telescopic rod 221 is hinged to the slider 212, so that the slider 212 slides on the first support plate 213 through the chute 8. Also, since the second flattening rod is rotatably connected to the slider 212, it drives the first flattening roller 211 to displace, thereby adjusting the distance between the first flattening roller 211 and the second flattening roller 5 to make it suitable for the thickness of the film-coated paper to be flattened. Then, the film-coated paper is passed through between the second flattening roller 5 and the first flattening roller 211 and guided below the flattening plate 33. The hydraulic cylinder 32 is adjusted to make the distance between the flattening plate 33 and the frame 1 reach the desired effect. The film-coated paper passes through the flattening plate 33, further enhancing the flattening effect on the film-coated paper. A fillet 7 is arranged on the flattening plate 33 to reduce the friction between the flattening plate 33 and the surface of the film-coated paper and prevent the bottom of the flattening plate 33 from causing frictional damage to the surface of the film-coated paper. Finally, the film-coated paper is guided to the transition roller 6 to guide the film-coated paper to the next process. The adjusting assembly 21 avoids the problem that when flattening film-coated papers of different thicknesses, it is inconvenient to adjust the distance between the two flattening rollers, resulting in poor flattening effect of the device.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
