Abstract
Description
Technical Field
[0001] This utility model relates to the field of cardboard processing technology, and in particular to a cardboard bonding and flattening device. Background Technology
[0002] A cardboard bonding flattening machine is a specialized processing equipment used in cardboard processing. It applies uniform pressure and uses a specific pressing method to eliminate defects such as air bubbles, wrinkles, and local bulges that may exist after the cardboard is bonded, so that the bonded surfaces of the cardboard are tightly bonded, the surface is flat, and the thickness is uniform.
[0003] Existing flattening methods have poor flattening effects and are not easy to adjust the flattening thickness, making them inconvenient to use.
[0004] An existing patent (publication number: CN221049140U) discloses a flattening device for bonding paperboard, including symmetrically arranged support frames. Each support frame is equipped with an adjustment component, which includes a rotatable rotating rod rotatably connected to the inner wall of the support frame. Each rotating rod is fitted with a liftable sliding box. Each rotating rod in the sliding box is slidably fitted with a horizontally arranged driving bevel gear. Each driving bevel gear has a symmetrically arranged insert block near one end of the rotating rod. The rotating rod has a slot that mates with the insert block. Each driving bevel gear meshes with a vertically arranged driven bevel gear. A driven rod is provided between the two driven bevel gears. Both ends of the driven rod are connected to the driven bevel gear. The driven rod is rotatably connected to the sliding box. A pressure roller is fitted on the driven rod. A support plate is provided below the pressure roller and connected to the support frame. Therefore, this utility model can quickly and efficiently flatten the bonded paperboard, and the thickness of the flattening can be adjusted at will, improving the flattening efficiency.
[0005] To address the aforementioned issues, existing patents have provided solutions. However, most existing cardboard bonding and flattening equipment lacks a feeding posture correction structure during use. When faced with warped or skewed cardboard, it is prone to transmission jams and path deviations, disrupting the flattening operation rhythm. At the same time, during the operation of the pressing rollers, it is difficult to effectively constrain the warped edges at both ends of the cardboard. The cardboard is prone to uneven pressing force due to the edges warping, resulting in uneven indentation, localized incomplete pressing, and other quality problems.
[0006] To address this, a flattening device for bonding cardboard is proposed. Utility Model Content

At the same time, when the pressing roller is working, it is difficult to effectively restrain the warped edges at both ends of the cardboard. The cardboard is prone to uneven pressing force due to the edge warping, resulting in uneven indentation, local missing pressing and other quality problems.

[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] 1. This application sets up a guiding mechanism, which works with a fixed plate and a connecting plate to provide stable guidance for the bonding paperboard. The fixed plate ensures the stable connection of the mechanism, and the connecting plate can drive the guiding plate to guide the paperboard feeding, ensuring that the paperboard is accurately delivered to the anti-warping roller and pressing roller assembly, and improving the adaptability of the pressing roller assembly to paperboard in different states.

[0029] In this embodiment: By setting a guiding mechanism 2, which cooperates with a fixed plate 201, a connecting plate 202 and a guiding plate 203, the guiding mechanism 2 provides stable guidance for the adhesive cardboard. The fixed plate 201 ensures the stable connection of the mechanism, and the connecting plate 202 can drive the guiding plate 203 to guide the cardboard feeding, ensuring that the cardboard is accurately delivered to the anti-warping roller 6 and the pressing roller assembly 3, improving the adaptability of the pressing roller assembly 3 to cardboard in different states. By setting a transmission frame 1, the transmission frame 1 provides continuous and stable transmission of the cardboard, avoiding interruptions that affect the flattening efficiency. The fixed frame 4 firmly supports the electric lifting rod 5, ensuring that it can flexibly adjust the height of the pressing roller assembly 3, accurately control the pressing pressure to adapt to cardboard of different specifications, prevent insufficient flattening or damage to the cardboard, and the pressing roller assembly 3 applies uniform pressure to eliminate air bubbles and wrinkles in the adhesive layer. The anti-warping roller 6 suppresses the warping of the cardboard edges, avoids missed pressure and uneven pressure marks during pressing, and ensures consistent flattening quality.
[0030] Specifically, such as Figure 2 , Figure 4 As shown, a lifting frame 7 is fixedly connected to the right side of the fixed plate 201, and a connecting block 8 is fixedly connected to the bottom of the lifting frame 7.
[0031] Specifically, such as Figure 4 As shown, the inner wall of the connecting block 8 is fixedly connected to the first bearing 9, and the inner wall of the first bearing 9 is fixedly connected to the surface of the anti-warping roller 6.
[0032] Specifically, such as Figure 2 , Figure 4 As shown, a limit plate 10 is provided on the top of the lifting frame 7. A support frame 11 is fixedly connected to the front and rear sides of the limit plate 10. The side of the support frame 11 closest to the transmission frame 1 is fixedly connected to the transmission frame 1.
[0033] In this embodiment: by setting up a lifting frame 7 and a connecting block 8, the lifting frame 7 is adapted to the connecting block 8 and the first bearing 9 during use, so that the anti-warping roller 6 can rotate on the inner wall of the connecting block 8 through the first bearing 9, which facilitates the subsequent stable rotation assistance of the anti-warping roller 6. By setting up a limiting plate 10 and a support frame 11, the position of the support frame 11 and the limiting plate 10 is fixed during use, which facilitates the subsequent adjustment of the height of the lifting frame 7 through the limiting, so that the anti-warping roller 6 can accurately fit the cardboard of different thicknesses, enhance the suppression effect of cardboard warping, and facilitate user use.
[0034] Specifically, such as Figure 6 As shown, the inner wall of the lifting frame 7 is fixedly connected to the mounting assembly 12, and the inner wall of the mounting assembly 12 is fixedly connected to the second bearing 13.
