Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, and more specifically, to a cardboard flattening device for corrugated cardboard processing. Background Technology

[0002] Corrugated cardboard is a multi-layered adhesive, consisting of at least one layer of corrugated core paper. It has good elasticity and extensibility and is mainly used to manufacture cartons, carton fillings, and other packaging materials for fragile goods. The corrugations of corrugated cardboard resemble a series of connected arches, arranged side by side and supporting each other to form a triangular structure, which has good mechanical strength.

[0003] However, in the existing technology, when bonding corrugated cardboard, the adhesive contains a certain amount of moisture and humidity. At the same time, due to external influences, one side of the corrugated cardboard may curl up during bonding, causing the corners to fold when flattened. Utility Model Content

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Reference Figures 1-4 This utility model provides a technical solution: a cardboard flattening device for corrugated cardboard processing, including a processing table 1 and an edge pressing mechanism. A top frame 2 is installed on the top of the processing table 1, and a hydraulic cylinder 3 is installed on the top of the top frame 2. A pressure plate 4 is installed on the free end of the hydraulic cylinder 3. After the cardboard is transported to the edge pressing mechanism, the edge pressing mechanism can be moved to press the edges of the cardboard, preventing the edges of the cardboard from curling up. This would cause the upper layer of cardboard to be flattened and folded during flattening. A heating plate is installed at the bottom of the pressure plate 4, which can quickly dry the glue on the cardboard, making it easier to flatten the cardboard after bonding.

[0030] Reference Figures 1-5In a preferred embodiment, an edge-pressing mechanism is provided, which includes a moving groove 5, an edge-pressing roller 6, and a movable rod 7. The moving groove 5 is opened on the left side of the front of the top frame 2, the edge-pressing roller 6 is disposed in the inner cavity of the top frame 2, and the movable rod 7 is respectively installed on the front and back of the edge-pressing roller 6. The movable rod 7 is slidably engaged with the moving groove 5, which can limit the movable rod 7 after the moving groove 5 is opened, so that the edge-pressing roller 6 and the movable rod 7 can be moved along the moving groove 5, thereby facilitating the edge pressing of the paperboard and improving the pressing effect of the paperboard.

[0031] Reference Figures 1-4 In a preferred embodiment, the pressing mechanism further includes a moving mechanism, which includes a movable groove 8. The movable groove 8 is respectively opened on the front and back of the top frame 2. Movable plates 9 are installed on both the front and back of the pressing plate 4, and the movable plates 9 slide in cooperation with the movable groove 5. When the hydraulic cylinder 3 drives the pressing plate 4 to move, the pressing plate 4 can drive the movable plates 9 to move in the movable groove 8. A toothed plate 10 is installed on the left side of the movable plate 9. Gears 11 that mesh with the toothed plates 10 are rotatably installed on both the front and back of the top frame 2. A take-up drum 12 is installed on the front of the gear 11. A first mounting block 13 is installed on the outer side of the movable rod 7. The surface of the take-up drum 12 is wound with... A pull rope 14 is wound around the top frame 2. One end of the pull rope 14 is connected to the take-up drum 12, and the other end of the pull rope 14 is connected to the first mounting block 13. When the toothed plate 10 moves, it drives the gear 11 to rotate, which in turn drives the take-up drum 12 to rotate and wind up the pull rope 14. This makes it easier for the pull rope 14 to pull the first mounting block 13, which in turn allows the first mounting block 13 to move the pressing roller 6 through the movable rod 7 to press the edge of the cardboard. In addition, rollers 15 are installed on both the front and back of the top frame 2, and there are two sets of rollers 15. The pull rope 14 is wound around the surface of the rollers 15, and the rollers 15 can guide the pull rope 14 to facilitate the pulling of the pressing roller 6.

[0032] Reference Figures 1-4 In a preferred embodiment, a second mounting block 16 is rotatably mounted on the front of the movable rod 7, and a first mounting block 13 is rotatably mounted on the outside of the second mounting block 16. A third mounting block 17 is rotatably mounted on the left side of both the front and back sides of the top frame 2. A spring 18 is mounted on the right side of the third mounting block 17, and the right end of the spring 18 is connected to the second mounting block 16. A telescopic rod 19 is mounted on the inner side of the third mounting block 17 and the second mounting block 16, which allows the spring 18 to be installed after the second mounting block 16 and the third mounting block 17 are installed. This facilitates the spring 18 to press against the second mounting block 16, thereby facilitating the reset of the movable rod 7 through the second mounting block 16. The installed telescopic rod 19 can guide and limit the second mounting block 16 and the third mounting block 17, preventing the spring 18 from being squeezed and deformed.

[0033] In addition, the inner cavity of the pressing roller 6 is provided with an installation groove 20, and a heating wire 21 is installed on the inner wall of the installation groove 20. This allows the heating wire 21 to be installed after the installation groove 20 is opened, so that the heating wire 21 heats the pressing roller 6 after being energized, thereby facilitating the pressing roller 6 to flatten the cardboard with raised edges and to dry the adhesive.

[0034] Specifically, the working process or working principle of the corrugated cardboard flattening device is as follows: When in use, the heating wire 21 and the heating plate are first energized. After the cardboard is conveyed to the pressure plate 4, the hydraulic cylinder 3 is activated, causing the hydraulic cylinder 3 to drive the pressure plate 4 and the heating plate to move downward to flatten the cardboard. When the pressure plate 4 moves downward, the pressure plate 4 can drive the moving plate 9 to move, so that the moving plate 9 rotates through the toothed plate 10 with the gear 11. This allows the gear 11 to drive the winding drum 12 to wind the pull rope 14, which in turn allows the pull rope 14 to pull the first mounting block 13. This causes the first mounting block 13 to move through the second mounting block 16, which in turn drives the movable rod 7 to move. This allows the movable rod 7 to drive the edge pressing roller 6 to move, so that after the edge pressing roller 6 moves, the warped cardboard is flattened. After flattening, the adhesive is dried, which facilitates the flattening and bonding of the cardboard.

[0035] It should be noted that the hydraulic cylinder 3 and the heating wire 21 are existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
