[0002] Paper products refer to various products made from pulp, cardboard, paper, etc. as raw materials through processing and manufacturing. Paper products are widely used in life, industry, commerce and other fields, and are one of the indispensable and important items in modern society. In the production process of paper products, it is often easy for paper corners to be wrinkled and curled, and a flattening device is needed to flatten the uneven paper. Existing flattening devices usually use a winding roller to flatten the paper, but it is easy to fail to flatten the corners of larger-sized papers, resulting in certain defects in the subsequent processing of paper products. It is difficult to adapt to papers of different sizes, which affects the scope of application of the flattening device, reduces the practicability of the flattening device, and is difficult to meet actual usage needs.

The flattening mechanism also includes a limiting component arranged on the frame for limiting the position of the corners of the paper.

[0006] Furthermore, the adjusting component includes limit seats which are rotatably arranged on two movable horizontal axes through bearings respectively, movable connecting rods are respectively arranged at the two ends of the top of the connecting horizontal tube, a movable seat which is slidably connected to the connecting vertical rod is hingedly arranged between the tops of the two movable connecting rods, and the bottom ends of the two movable connecting rods are respectively hinged to the two limit seats.

[0007] Furthermore, a threaded seat is fixedly arranged on one side of the movable seat, and a motor is fixedly arranged on the top of the frame.

[0008] Furthermore, a threaded vertical shaft penetrating the threaded seat and threadedly connected thereto is fixedly arranged at the bottom of the output shaft of the motor, and the bottom end of the threaded vertical shaft is rotatably connected to the annular seat via a bearing.

[0009] Furthermore, the limiting component includes a connecting frame fixedly arranged on the top of the two limiting seats respectively, and strip slide grooves are opened at both ends of the top of the frame body, and the top of the connecting frame passes through the strip slide groove and is slidably connected thereto.

[0010] Furthermore, a support frame is fixedly arranged on one side of the connecting frame, and U-shaped pressure rods are fixedly arranged on both ends of the support frame.

[0011] The utility model provides an adjustable paper product leveling device, which has the following beneficial effects compared with the prior art:

[0012] 1. By setting up a flattening mechanism, the edges and corners of larger-sized paper can be flattened. The spacing between the two movable pressing rollers is adjusted by an adjusting component so that the spacing between the two movable pressing rollers is adapted to the size of the paper to be flattened.
