[0026] Please refer to Figures 1 to 6This application provides a paper leveling device, including a workbench 1, leveling mechanisms 2, and a frame 3. A rotating component 4 is provided below the workbench 1, which can drive the workbench 1 to rotate. Two leveling mechanisms 2 are symmetrically arranged on the frame 3. Each leveling mechanism 2 includes a mounting base 21, a telescopic component 22, and a sliding plate 23. The mounting base 21 is connected to the frame 3. The telescopic component 22 is disposed on the mounting base 21 and performs telescopic movement in the horizontal direction. The sliding plate 23 is connected to the output end of the telescopic component 22, and the telescopic direction of the sliding plate 23 is perpendicular to that of the telescopic component 22. A leveling plate 24 is provided on the side of the sliding plate 23 away from the telescopic component 22. The leveling plate 24 is used to contact the edge of the paperboard during leveling.

[0027] In this application, the pallet 7 containing stacked cardboard at the bottom of the production line is transferred to the workbench 1, with the two leveling mechanisms 2 positioned on opposite sides of the cardboard. The telescopic component 22 allows the sliding plate 23 and the leveling plate 24 to move closer to or further away from the cardboard, enabling the leveling plate 24 to clamp and level both sides of the stacked cardboard. After leveling both sides of the cardboard, the relative positions of the two leveling mechanisms 2 are adjusted, and then the workbench 1 is rotated 90° via the rotating component 4. This allows the leveling plate 24 to clamp and level the other two sides of the stacked cardboard again, ensuring that the edges of the stacked cardboard are aligned. This prevents deformation or damage to the cardboard edges during subsequent packing with strapping.

[0028] It should be noted that before rotating the worktable 1 90°, it is not necessary to adjust the overall relative position of the two leveling mechanisms 2. Instead, the relative distance between the two sliding plates 23 can be adjusted by moving the telescopic component 22, so that the distance between the two leveling plates 24 is increased, thus not affecting the rotation of the cardboard with the worktable 1.

[0029] According to a feasible embodiment of this application, a sliding rod 25 is provided on the side of the flat plate 24 facing the sliding plate 23. Multiple sliding rods 25 are parallel to each other and are slidably connected to the sliding plate 23. A spring 26 is sleeved on each sliding rod 25, and the spring 26 is located between the flat plate 24 and the sliding plate 23. By using the sliding rods 25 and the spring 26 to slidably mount the flat plate 24 onto the sliding plate 23, the flat plate 24 can float towards the sliding plate 23 when it contacts the edge of the cardboard, providing a buffer when the flat plate 24 contacts the edge of the cardboard. This avoids damage caused by rigid contact between the flat plate 24 and the edge of the cardboard.

[0030] According to one feasible embodiment of this application, a limiting nut 27 is provided at the end of the slide rod 25 away from the flat plate 24. The limiting nut 27 is located on the side of the sliding plate 23 opposite to the flat plate 24. By providing the limiting nut 27 on the slide rod 25, the slide rod 25 can be prevented from disengaging from the sliding plate 23 when the spring 26 pushes the flat plate 24 to reset. At the same time, the floating amount of the flat plate 24 relative to the sliding plate 23 can be adjusted by adjusting the position of the limiting nut 27 on the slide rod 25.

[0031] According to one feasible embodiment of this application, a guide rod 28 is provided on the side of the sliding plate 23 facing the telescopic member 22. There are multiple guide rods 28 that are parallel to each other, and the guide rods 28 are slidably connected to the mounting base 21. By providing the guide rods 28, a guiding function can be provided when the telescopic member 22 drives the sliding plate 23 to move left and right, making the sliding plate 23 move smoothly.

[0032] Specifically, a guide hole is provided on the mounting base 21, and the guide rod 28 passes through the guide hole. When the telescopic member 22 drives the sliding plate 23 to move left and right, the guide rod 28 slides in the guide hole.

[0033] According to one feasible embodiment of this application, the two mounting seats 21 are slidably connected to the frame 3, and the two mounting seats 21 slide synchronously relative to the worktable 1. By allowing the two mounting seats 21 to slide relative to each other on the frame 3, the relative distance between the two leveling mechanisms 2 can be adjusted over a wide range to accommodate a wider range of cardboard sizes, while reducing the extension stroke requirement of the telescopic member 22. That is, with this configuration, the telescopic member 22 only drives the sliding plate 23 to move within a small range, while the relative position of the two leveling mechanisms 2 on the frame 3 can be pre-adjusted according to the cardboard size.

[0034] According to one feasible embodiment of this application, the frame 3 includes a crossbeam 31 and columns 32 disposed at both ends of the crossbeam 31. The mounting base 21 is inverted L-shaped and slidably connected to the crossbeam 31. Specifically, the columns 32 are arranged vertically and their lower ends are fixed to the ground, while the crossbeam 31 is arranged horizontally and its two ends are fixed to the tops of the two columns 32. That is, the frame 3 has a portal-shaped structure, spanning both sides of the workbench 1, and two leveling mechanisms 2 are symmetrically arranged on the crossbeam 31 of the frame 3.

[0035] Specifically, the mounting base 21 includes a horizontal plate 211 and a vertical plate 212. The horizontal plate 211 is located at the top of the vertical plate 212, and the horizontal plate 211 and the vertical plate 212 are perpendicular to each other, forming an inverted L-shaped structure. Triangular reinforcing plates 213 are provided on the inner sides of the horizontal plate 211 and the vertical plate 212 to enhance the overall structural rigidity of the mounting base 21. The mounting base 21 is slidably connected to the crossbeam 31 through its horizontal plate 211.

[0036] According to a feasible embodiment of this application, the crossbeam 31 is provided with a guide groove and a driving mechanism; a lead screw 51 is provided in the guide groove, the lead screw 51 is a positive and negative threaded lead screw 51, and a slider 52 is respectively provided on the positive and negative threaded sections of the lead screw 51. The two sliders 52 cooperate with the guide groove and are connected to the two mounting seats 21; the driving mechanism is used to drive the lead screw 51 to rotate, so as to drive the two mounting seats 21 to move relative to each other.

[0037] Specifically, the guide groove extends along the length of the crossbeam 31, and its cross-section has a T-shaped structure. The lead screw 51 is rotatably mounted in the guide groove via four support seats 53. Two sliders 52 are fitted in the guide groove and respectively engage with the positive and negative threaded sections of the lead screw 51. The two sliders 52 are also connected to the cross plates 211 of the two mounting seats 21. By rotating the lead screw 51, the two sliders 52 can slide in opposite directions, thereby allowing the two mounting seats 21 to slide synchronously towards the center.

[0038] The aforementioned drive mechanism is used to drive the lead screw 51 to rotate. The drive mechanism includes a drive motor 54 and a transmission structure 55. The drive motor 54 can be arranged on the crossbeam 31, specifically in the middle of the crossbeam 31 or at one end of the crossbeam 31. In this example, the drive motor 54 is arranged in the middle of the crossbeam 31 and is connected to the middle of the lead screw 51 through the transmission structure 55.

[0039] The transmission structure 55 can be either belt drive or chain drive. In this example, chain drive is used. Specifically, it includes a driving sprocket, a driven sprocket, and a chain. The driving sprocket is mounted on the output shaft of the drive motor 54, the driven sprocket is mounted on the lead screw 51, and the chain connects the driving sprocket and the driven sprocket. The drive motor 54 drives the lead screw 51 to rotate.

[0040] To facilitate the installation of the driven sprocket, the diameter of the middle section of the lead screw 51 can be slightly larger, allowing the driven sprocket to be fitted onto the lead screw 51 from one end. Simultaneously, a clearance opening is provided on the crossbeam 31 to allow the chain to pass through it. In this example, four support seats 53 are used to support the lead screw 51 for flexible rotation. The diameter of the lead screw 51 at the corresponding positions on the four support seats 53 can be different, and the specific design can be tailored to actual needs.

[0041] According to one feasible embodiment of this application, the workbench 1 is provided with two slide rails 11 arranged in parallel, and the distance between the two slide rails 11 is adapted to the tray 7 used for placing stacked paper.

[0042] Specifically, the two slide rails 11 can be slide rails 11 with rollers 111, that is, multiple cylindrical rollers 111 are evenly arranged on the slide rail 11 along the length direction. By setting the rollers 111 to contact the lower side of the pallet 7, rolling friction is achieved, which makes it easier to transfer the pallet 7 with stacked cardboard to the slide rail 11 for placement.

[0043] The workbench 1 in this application can be arranged at the bottom of the cardboard conveyor line, and the workbench 1 can be rotated by the rotating component 4 so that the direction of the slide rail 11 on the workbench 1 is consistent with the transmission direction of the cardboard conveyor line, thereby facilitating the smooth transfer of the pallet 7 of stacked cardboard to the slide rail 11 on the workbench 1.

[0044] According to one feasible embodiment of this application, the rotating component 4 is an electrically controlled rotary table. This electrically controlled rotary table has a fixed portion and a rotating portion, wherein the fixed portion is disposed on the base plate 6, and the rotating portion is connected to the lower side of the worktable 1. When the electrically controlled rotary table is in operation, it drives the worktable 1 to rotate via the rotating portion, and can precisely control the rotation of the worktable 1 by 90°, so as to use the flat plate 24 to clamp and flatten the other two sides of the stacked cardboard.

[0045] According to one feasible embodiment of this application, the telescopic component 22 is a cylinder. The cylinder body is fixedly mounted on the vertical plate 212 of the mounting base 21, and the piston rod of the cylinder passes through the vertical plate 212 of the mounting base 21 and is fixedly connected to the sliding plate 23, thereby driving the sliding plate 23 to move horizontally in the left and right directions through the extension and retraction of the piston rod. Of course, the telescopic component 22 can also be a hydraulic cylinder or an electric push rod, or other telescopic components.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
