[0033] When the device is used for work, the paper is placed flat on the conveyor table 2. The conveyor table 2 serves as the basis for placing the paper, and its flat surface can provide stable support for the paper. At this time, by starting the motor 12, the motor 12 serves as a power source and can convert electrical energy into mechanical energy to provide power for the rotation of the roller 11. The controllability of its speed and steering enables the roller 11 to perform precise motion control according to actual work requirements, thereby realizing precise operation of paper limiting, allowing it to drive the roller 11 on one side to rotate, and the roller 11 rotates under the drive of the motor 12, and the power of the motor 12 is transmitted to the belt 13, thereby realizing the linkage of the entire limiting component. This drives the belt 13 to rotate. Belt 13, as a transmission component, connects roller 11 and fixed block 2 14. It can effectively convert the rotation of roller 11 into the linear motion of fixed block 2 14, so that belt 13 drives fixed blocks 2 14 on both sides to move. Fixed block 2 14 is tightly connected to belt 13 and moves synchronously with the rotation of belt 13. As an intermediate component connecting belt 13 and fixed plate 7, it can accurately transmit the linear motion of belt 13 to fixed plate 7, thereby driving fixed plate 7 and the components thereon to move together, achieving adjustment of the position of limit plate 1 9. This drives the movement of fixed plate 7, which is used to fix components such as side plate 8 and limit plate 1 9, ensuring the relative position stability between these components, so that they can move synchronously with the movement of fixed block 2 14, providing stable support and accurate position adjustment for limit plate 1 9 to limit the paper, ensuring the reliability of the limiting effect. At the same time, slider 6 slides along the sidewalls of fixed block 5. The sliding cooperation between slider 6 and fixed block 5 provides stable guidance and support for the movement of fixed plate 7, enabling fixed plate 7 to maintain smooth vertical movement, reducing shaking and deviation of fixed plate 7 during movement, and further improving the overall stability and positioning accuracy of the limiting assembly. Limiting plate 9 is used to limit the two sides of the paper. As a limiting component that directly contacts the paper, limit plate 9 can accurately limit the edge position of the paper according to the width and transportation requirements of the paper through its own position movement, preventing the paper from lateral deviation during transportation, ensuring that the paper can accurately enter the printing area, thereby improving the accuracy and quality of printing. Preventing paper deviation during transportation. Through the coordinated operation of the above series of components, especially the effective positioning of limit plate 9 on both sides of the paper, it can prevent the paper from deflecting or skewing due to various factors during transportation, ensuring that the paper is always in the correct transportation position, providing a stable and reliable paper supply for subsequent printing operations, and helping to improve printing efficiency and product quality.

[0034] Reference Figure 1 and Figure 3The smoothing component includes a mounting plate 2 15. The lower surface of the mounting plate 2 15 is fixedly connected to the upper surface of the base 1. The mounting plate 2 15 serves as the basic supporting component of the smoothing component and plays the role of fixing and carrying other components. The mounting plate 2 15 is internally provided with a squeezing roller 17. The squeezing roller 17 is a key component that directly contacts the paper and smoothes it. Through its own rotation, it applies a certain pressure to the surface of the paper, so that the paper can be fully smoothed during the transmission process, reducing the wrinkles and unevenness of the paper surface, thereby improving the flatness of the paper ... A fixed connection is provided with a fixing ring 20, which is mainly used to fix the slide bar 19 and limit the moving range of the slide bar 19. The slide bar 19 is slidably connected inside the fixing ring 20. The slide bar 19 serves as a connecting component. On the one hand, it connects the mounting plate 3 16 with the fixing ring 20, so that the mounting plate 3 16 can move accordingly under the drive of the slide bar 19; on the other hand, the slide bar 19 cooperates with the fixing ring 1 18 and the spring 22 to realize the functions of elastic connection and buffering, and can automatically adjust the pressure of the squeezing roller 17 on the paper according to the thickness and surface condition of the paper. The spring 22 is fixedly connected to the side wall of the slide bar 19, and the other end of the spring 22 is fixedly connected to the side wall of the fixing ring 18. The main function of the spring 22 is to provide elastic force. When the thickness of the paper changes or the degree of surface unevenness varies, the spring 22 can automatically expand and contract according to the actual situation, adjust the pressure between the squeezing roller 17 and the paper, so that the squeezing roller 17 can always be in contact with the paper with appropriate pressure, ensuring the consistency of the smoothing effect, and at the same time can also play a role of buffering and shock absorption, reducing the impact on the paper and other components during the smoothing process. The other end of the slide rod 19 is fixedly connected to a limit plate 21. The limit plate 21 is used to limit the maximum displacement of the slide rod 19 to prevent the slide rod 19 from exceeding the normal working range during movement, thereby ensuring that the relative position relationship between the various components of the smoothing assembly is stable, thereby ensuring that the overall structure and function of the smoothing assembly are not damaged and extending the service life of the smoothing assembly.

[0035] The primary function of the conveyor roller 3 is to provide stable conveying power for the paper through its continuous rotation, driving the paper forward smoothly within the device and ensuring that the paper can smoothly enter the working area between the conveyor roller 3 and the squeeze roller 17. The surface of the conveyor roller 3 is typically roughened or made of a special material to increase friction with the paper, preventing slippage during conveyance and ensuring accurate and stable paper transmission. The squeeze roller 17 is a key component that directly acts on the paper, working in conjunction with the conveyor roller 3 to apply uniform pressure to the paper passing between them. This squeezing action effectively eliminates wrinkles and unevenness that may occur during paper production, handling, or storage, resulting in a smoother and flatter surface, providing an ideal foundation for high-quality printing. The spring 22 plays a crucial role in the entire system, providing elastic support and cushioning. Due to its excellent elastic properties, it can automatically adjust the pressure between the squeeze roller 17 and the paper according to the thickness and flatness of the paper, as well as various changes during conveyance. When the paper is thick or has a very uneven surface, spring 22 compresses accordingly, increasing the pressure of squeezing roller 17 on the paper to ensure it is fully smoothed. When the paper is thin or has a relatively flat surface, spring 22 rebounds appropriately, reducing the pressure of squeezing roller 17 on the paper and preventing damage caused by excessive squeezing. This adaptive pressure adjustment function not only effectively maintains the flatness of the paper but also achieves optimal smoothing under varying paper conditions. Furthermore, spring 22 absorbs and mitigates the impact and vibration that may occur during the squeezing process, reducing the impact on the paper and other equipment components, thereby reducing the internal stress of the paper after printing and extending the service life of the equipment.

[0036] Working principle: When using the device to work, the paper is placed flat on the conveyor table 2, which drives the paper to move. At this time, the motor 12 is started to drive the roller 11 on one side to rotate, thereby driving the belt 13 to rotate, and the belt 13 drives the fixed blocks 14 on both sides to move, thereby driving the fixed plate 7 to move. At the same time, the slider 6 slides on the side wall of the fixed block 5, so that the limit plate 9 limits the two sides of the paper to prevent the paper from shifting during the conveying process. The paper is passed between the conveying roller 3 and the squeezing roller 17. Due to the elasticity of the spring 22, the squeezing roller 17 squeezes the paper, thereby keeping the paper flat and reducing the internal stress of the paper after printing.
