[0005] Finally, without automation, the entire process requires manual intervention, which increases the complexity of the operation. Operators not only need to manually adjust the pressure, but also need to constantly monitor humidity and moisture evaporation, which increases the workload and makes it easy for oversights to occur.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-5 A corrugated cardboard flattening device includes a main body 1, a force adjustment mechanism, and a running mechanism. The force adjustment mechanism includes a force plate 2, a first motor 3, a transmission belt 4, a rotating cylinder 5, a clamping component 6, and auxiliary components. The force plate 2 is mounted on the main body 1 and slidably connected to it. The first motor 3 is fixedly mounted on the main body 1 and connected to the transmission belt 4. One end of the transmission belt 4 is connected to the rotating cylinder 5. The clamping component 6 is installed inside the rotating cylinder 5 and is slidably connected to the rotating cylinder 5 and threadedly engaged with the force plate 2. The auxiliary components include a mounting block 7, a force spring 8, and a roller 9. The mounting block 7 is mounted on the main body 1 and threadedly engaged with it. One end of the force spring 8 is connected to the force plate 2, and the other end is installed inside the mounting block 7 and rotatably connected to it. The roller 9 is installed in the force plate 2 and rotatably connected to it.

[0032] In this embodiment, the hand-operated adjustment mechanism includes a force-bearing plate 2, a first motor 3, a transmission belt 4, a rotating cylinder 5, a meshing member 6, and auxiliary components. During use, the threaded rod 28 on the force-bearing plate 2 is threadedly engaged with the meshing member 6. The first motor 3 is driven, and the connecting block 26 on the first motor 3 rotates, causing the transmission belt 4, which is installed in the placement groove 27, to rotate. This causes the rotating cylinder 5 to rotate, and the rotation of the rotating cylinder 5 causes the limiting block 30 on the meshing member 6 to rotate under the action of the limiting slide groove 31 in the rotating cylinder 5. This allows the meshing member 6 to engage with the threaded rod 28, enabling the threaded rod 28 to mesh... The component 6 rotates and descends on the main body 1, thereby compressing the spring. Although the position of the force plate 2 is lowered at this time, the force required to squeeze the force plate 2 again is greater. After the operator places the cardboard on the force plate 2, he can input the size and thickness of the corrugated cardboard on the operation screen 15 on the main body 1. The operation screen 15 will determine the descending position of the force plate 2 on the main body 1 based on the spring force, thereby driving the first motor 3 to rotate. The side of the force plate 2 that contacts the cardboard has a large friction force, so there is no need to worry about the cardboard sliding on the force plate 2 during the flattening process.

[0033] In this embodiment, the auxiliary components include a mounting block 7, a force-bearing spring 8, and a roller 9. During use, the spring may become fatigued after repeated use and therefore needs to be replaced. In this case, the rotating block 25 on the spring can be placed in the mounting block 7, and the mounting block 7 can be assembled. The magnetic block 23 on the mounting block 7 enters the insertion hole 22 in the mounting block 7, so that the mounting blocks 7 can be assembled together. The mounting block 7 is then installed on the main body 1 and passes through the stabilizing rod 29, so that one end of the spring can contact the force-bearing plate 2. When the force-bearing plate 2 is adjusting the force intensity, the force-bearing plate 2 slides on the main body 1, the connecting plate 19 on the force-bearing plate 2 slides in the second slide groove 17 of the main body 1, and the roller 9 installed on the force-bearing plate 2 slides in the third slide groove 18, which facilitates the force-bearing plate 2 to receive force evenly.

[0034] In this embodiment, the operating mechanism includes a second motor 10, a lead screw 11, a sliding frame 12, a flattening roller 13, and a steam roller 14. In use, after the cardboard is placed on the force plate 2, the thickness, size, and other data of the cardboard can be input on the operation screen 15. Then, the operation screen 15 operates the force adjustment mechanism, and the operating mechanism then runs. At this time, the second motor 10 drives the lead screw 11 to rotate inside the main body 1 and drives the sliding frame 12 to slide in the first slide groove 16. Under the control of the operation screen 15, when the sliding frame 12 passes the cardboard without flattening it, water is input into the sliding frame 12 through the connecting pipe 21 and sprayed onto the connecting plate 19. Then, the flattening roller 13 flattens the cardboard. The steam roller 14 behind the flattening roller 13 evaporates the water sprayed out, thereby ensuring that the structure of the cardboard is not damaged due to excessive moisture.

[0035] Example 2:

[0036] In summary, during use, after placing the cardboard onto the force plate 2, the cardboard's thickness, dimensions, and other data can be input on the operation screen 15. The operation screen 15 then operates the force adjustment mechanism. At this time, the threaded rod 28 on the force plate 2 engages with the engaging member 6. The first motor 3 drives the first motor 3, and the connecting block 26 on the first motor 3 rotates, causing the transmission belt 4 installed in the placement groove 27 to rotate, thereby causing the rotating cylinder 5 to rotate. The rotation of the rotating cylinder 5 causes the limiting block 30 on the engaging member 6 to rotate under the action of the limiting slide groove 31 in the rotating cylinder 5, thus causing the engaging member 6 to engage with the threaded rod 28, allowing the threaded rod 28 to... The spring is compressed by rotating within the interlocking member 6 and lowering its position on the main body 1. Although the position of the force plate 2 is lowered at this time, a greater force is required to compress the force plate 2 again. After the operator places the cardboard onto the force plate 2, they can input the size and thickness of the corrugated cardboard on the operation screen 15 on the main body 1. The operation screen 15 will determine the lowering position of the force plate 2 on the main body 1 based on the spring force, thereby driving the first motor 3 to rotate. Furthermore, the side of the force plate 2 that contacts the cardboard has a large friction force, so there is no need to worry about the cardboard sliding on the force plate 2 during the flattening process. However, the spring... After repeated use, fatigue occurs, necessitating replacement. At this point, the rotating block 25 on the spring is placed in the mounting block 7, and the mounting blocks 7 are assembled. The magnetic block 23 on the mounting block 7 enters the insertion hole 22 in the mounting block 7, allowing the mounting blocks 7 to be assembled together. The mounting blocks 7 are then installed onto the main body 1, passing through the stabilizer rod 29, so that one end of the spring can contact the force plate 2. When adjusting the force intensity, the force plate 2 slides on the main body 1, and the connecting plate 19 on the force plate 2 slides in the second groove 17 of the main body 1. The roller 9 mounted on the force plate 2 slides in the third groove. The sliding mechanism 18 facilitates even force distribution on the force-bearing plate 2. When everything is ready, the cardboard needs to be flattened. At this time, the second motor 10 drives the lead screw 11 to rotate inside the main body 1 and drives the sliding frame 12 to slide in the first slide groove 16. Under the control of the operation screen 15, when the sliding frame 12 passes the cardboard and is not flattened, the connecting pipe 21 inputs water into the sliding frame 12 and sprays it onto the connecting plate 19. Then, the flattening roller 13 flattens the cardboard. The steam roller 14 behind the flattening roller 13 evaporates the water sprayed, thereby ensuring that the structure of the cardboard is not damaged due to excessive moisture.

[0037] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
