[0002] Paper, a thin sheet made of plant fibers, is used for writing, drawing, printing books and newspapers, packaging, etc. During use, paper often wrinkles, which not only affects its appearance but also its normal use. Once wrinkles appear, correction devices are needed. However, many correction devices use heated rollers to press the paper to correct it, but they do not have a tensioning structure. As a result, when the rollers press the paper tightly, indentations often occur, leading to poor correction quality. Utility Model Content
[0003] To overcome the above shortcomings, this application provides an automatic paper surface flatness correction device, which aims to improve the paper correction by using rollers to press the paper. However, since no tensioning structure is provided, indentations often occur when the rollers press the paper tightly, resulting in poor correction quality.
[0004] This application provides an automatic paper surface flatness correction device, including a frame and a correction component. The correction component includes a feeding rack, a first bidirectional slide rail, a second bidirectional slide rail, a head pressing component, and a middle pressing component. The bottom of the feeding rack is slidably connected to the upper part of one side of the frame. The first bidirectional slide rail is disposed in the middle of the frame. The second bidirectional slide rail is symmetrically disposed on the two sliding ends of the first bidirectional slide rail. The head pressing component is symmetrically disposed on the two sliding ends of the second bidirectional slide rail. The middle pressing component is symmetrically disposed between the two second bidirectional slide rails.
[0005] In one specific implementation, the feeding rack includes a first linear slide rail, a support frame, a pressure plate, and a second linear slide rail.

The second motor is fixedly connected to the frame. Multiple first bidirectional threaded rods are provided. The output end of the second motor is drivenly connected to one of the first bidirectional threaded rods. Multiple first bidirectional threaded rods are drivenly connected to each other. The first symmetrical frame is slidably connected to the frame and threadedly connected to the first bidirectional threaded rod.
[0008] In one specific implementation, the output end of the second motor is provided with a first pulley, the first bidirectional threaded rod is provided with a second pulley, the first pulley is connected to one of the second pulleys in a transmission connection, and the multiple second pulleys are connected to each other in a transmission connection.

[0012] Beneficial Effects: This application provides an automatic paper surface flatness correction device. In use, the middle part of the paper to be corrected is clamped in the clamping end of the feeding rack. The feeding rack moves to the middle area between two second bidirectional slide rails. The sliding end of the first bidirectional slide rail drives the movement of the second bidirectional slide rail. The moving end of the second bidirectional slide rail drives the head pressing elements, clamping two head pressing elements on one side of the paper and the other two head pressing elements on the other side of the paper.

[0024] The working principle of this automatic paper surface flatness correction device is as follows: In use, the middle part of the paper to be corrected is first clamped at the clamping end of the feeding rack 210. The paper is transferred to the middle area of the two sets of second bidirectional slide rails 230 by the movement of the feeding rack 210. Then, the sliding end of the first bidirectional slide rail 220 drives the second bidirectional slide rail 230 to move laterally, causing the head pressing parts 240 on it to move synchronously. The two sets of head pressing parts 240 clamp and position the paper from both sides. Then, the first bidirectional slide rail 220 continues to drive the second bidirectional slide rail 230 to move in the opposite direction, generating a symmetrical pulling force on the paper, so that the middle part of the paper naturally unfolds. At this time, the symmetrically arranged middle pressing parts 250 descend synchronously to clamp and press the middle part of the paper to shape it. Through the linkage mechanism of clamping and positioning, bidirectional pulling, and middle pressing, mechanical force is evenly applied to the middle part of the paper. Compared with the traditional unidirectional pressing method, it not only significantly improves the correction effect, but also effectively reduces the generation of indentations, ensuring the dual optimization of paper surface flatness and correction quality.
[0025] It should be noted that the telescopic component 252 is an electric push rod.
