[0035] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0036] Please refer to Figures 1 to 5 A paper product leveling device, comprising:

[0037] Rack 1;

[0038] First conveyor belt 2, first conveyor belt 2 is connected to frame 1, first conveyor belt 2 conveys along X direction;

[0039] The second conveyor belt 3 is connected to the frame 1. The conveying direction of the second conveyor belt 3 is the same as that of the first conveyor belt 2. The beginning of the second conveyor belt 3 is located at the end of the first conveyor belt 2.

[0040] The lower pressure roller 4 is rotatably connected between the first conveyor belt 2 and the second conveyor belt 3.

[0041] The first drive motor 5 is used to drive the lower pressure roller 4 to rotate.

[0042] Top plate 11 is connected to frame 1 and is located above the lower pressure roller 4. A fixing frame 111 is provided at the lower part of top plate 11 and the fixing frame 111 is connected to the lower part of top plate 11 through elastic element 112.

[0043] The upper pressure roller 1111 is rotatably connected to the fixed frame 111. The rotation direction of the upper pressure roller 1111 is opposite to that of the lower pressure roller 4. The upper pressure roller 1111 is located above the lower pressure roller 4 and is parallel to the lower pressure roller 4. A first gap is provided between the upper pressure roller 1111 and the lower pressure roller 4 for paper products to pass through.

[0044] The second drive motor 1112 is connected to the outside of the fixed frame 111 and is used to drive the upper pressure roller 1111 to rotate.

[0045] In the above embodiments, the paper product is placed at the beginning of the first conveyor belt 2 and transported from the beginning to the end of the first conveyor belt 2. It passes between the upper pressure roller 1111 and the lower pressure roller 4. The upper pressure roller and the lower pressure roller 4 rotate in opposite directions, allowing the paper product to pass through and be guided onto the second conveyor belt 3. When the paper product passes through the flattening area formed between the lower pressure roller 4 and the upper pressure roller 1111, the upper pressure roller 1111 will float upward against the spring force according to the thickness of the paper product, and the spring will be further compressed, thereby applying continuous and stable rolling pressure to the paper product. Compared with the prior art, by fixing the lower pressure roller 4 between the first conveyor belt 2 and the second conveyor belt, the paper product is transported by the first conveyor belt 2 and the second conveyor belt 3. Then, the upper pressure roller 1111 is connected to the top plate 11 through the elastic member 112, so that the upper pressure roller 1111 can continuously generate pressure on the lower pressure roller 4. This is suitable for paper products of different thicknesses. It is not only simple in structure and easy to operate, but also has a good flattening effect on the paper product.

[0046] As an optional implementation, a transition plate 6 is provided between the first conveyor belt 2 and the second conveyor belt 3. The transition plate 6 is flush with the belt surface of the first conveyor belt 2 and the second conveyor belt 3. A groove 61 is provided in the transition plate 6. The lower pressure roller 4 is rotatably connected in the groove 61. The first drive motor 5 is connected to the outside of the transition plate 6 and is driven by the lower pressure roller 4.

[0047] In the above embodiments, by setting the transition plate 6, the paper products can be smoothly conveyed to the lower pressure roller 4 and the second conveyor belt 3.

[0048] As an optional implementation, the conveyor shafts at both ends of the lower pressure roller 4 are provided with a first pulley 7 and a second pulley 8. The first pulley 7 is connected to the first conveyor belt 2 via a belt, and the second pulley 8 is connected to the second conveyor belt 3 via a belt.

[0049] In the above embodiments, by setting the first drive motor 5, the first conveyor belt 2, the second conveyor belt 3 and the lower pressure roller 4 can be driven to rotate simultaneously, which greatly reduces the cost of the device.

[0050] As an optional implementation, the top plate 11 is provided with a connecting pipe 113, the axial direction of the connecting pipe 113 is parallel to the axial direction of the lower pressure roller 4, the connecting pipe 113 is located on the side of the lower pressure roller 4 facing the first conveyor belt 2, and a plurality of jet pipes 1131 are arranged in sequence along the axial direction of the lower part of the connecting pipe 113 facing the transition plate 6, and the connecting pipe 113 is connected to a high-temperature steam pipe in the outside.

[0051] In the above embodiments, steam is introduced into the connecting pipe 113 through a high-temperature steam pipe. The connecting pipe 113 wets and heats the paper product through the jet pipe 1131. Then, the paper product is hot-pressed by the lower pressure roller 4, which improves the shaping effect and thus results in a good flatness.

[0052] As an optional implementation, the top plate 11 is provided with a plurality of fans 114, which are arranged along the axial direction of the lower pressure roller 4 and are located on the side of the lower pressure roller 4 facing the second conveyor belt 3.

[0053] In the above embodiments, after the lower pressure roller 4 and the upper pressure roller 1111 have hot-pressed the paper product, the fan 114 blows towards the surface of the paper product, and the heat of the paper product can be carried away by the airflow to complete the cooling.

[0054] As an optional implementation, a limiting rod 9 is connected to the fixing frame 111, and a through hole 115 is provided on the top plate 11 through which the limiting rod 9 passes.

[0055] In the above embodiments, by setting the limiting rod 9 and the through hole 115, the fixing frame 111 can move stably in the vertical direction, thereby allowing the upper pressure roller 1111 to apply pressure vertically to the lower pressure roller 4.

[0056] As an optional implementation, the elastic element 112 is a spring, and several springs are arranged along the axial direction of the upper pressure roller 1111.

[0057] As an optional implementation, the first conveyor belt 2 is provided with a guiding mechanism 21. The guiding mechanism 21 consists of two guiding devices 211 symmetrically arranged on both sides of the first conveyor belt 2. The guiding device includes a cylinder 213 and a limiting plate 212.
