Detailed Implementation

[0022] 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.

[0023] Reference Figures 1-3 This utility model provides an embodiment of a paper flipping mechanism for paper printing and processing, comprising: a base plate 1 serving as a supporting body; a fixed frame 2 connected to the base plate 1 via a rotating assembly; a connecting box 3 fixedly connected to the inner wall of the fixed frame 2; connecting blocks 4 fixedly connected to both sides of the inner wall of the connecting box 3; a first motor 5 fixedly connected to the right end of each connecting block 4; a turntable 8 connected to the first motor 5 via a transmission assembly; a pull plate 9 rotatably connected to the bottom end of each turntable 8; a slide table 10 slidably connected to the inner wall of the connecting box 3; a positioning plate 11 fixedly connected to the bottom end of each slide table 10; and a rotatably connected top end of each slide table 10 to the pull plate 9. At the bottom, electric push rods 13 are fixedly connected to both sides of the top of the fixed frame 2. The driving end of the electric push rod 13 passes through the fixed frame 2 and is fixedly connected to a moving plate 14. The moving plate 14 and the inner wall of the fixed frame 2 are both provided with rotating rollers 15. The transmission assembly includes a worm 6 located at the driving end of the first motor 5 and a worm wheel 7 located on the outer wall of the turntable 8. The worm 6 and the worm wheel 7 are meshed together. The bottom end of the positioning plate 11 is fixedly connected to a slider 12. The outer wall of the slider 12 is slidably connected to the inner wall of the fixed frame 2. The outer wall of the turntable 8 is rotatably connected to the inner wall of the connecting box 3. The outer wall of the moving plate 14 is slidably connected to the inner wall of the fixed frame 2.

[0024] Specifically, when paper positioning is required, the first motor 5 is started, and its drive end rotates, which in turn drives the connected worm gear 6 to rotate synchronously. The rotation of the worm gear 6 causes the worm wheel 7 to rotate accordingly. Since the worm wheel 7 is fixedly connected to the turntable 8, its rotation drives the turntable 8 to rotate smoothly. During the rotation of the turntable 8, a specific connecting structure pulls the pull plate 9 to move. The movement of the pull plate 9 further drives the slide table 10 to move smoothly on a predetermined track. The slide table 10 is fixedly connected to the positioning plate 11, which enables the positioning plate 11 to accurately position the paper. The positioning operation of the positioning plate 11 effectively ensures the accurate position of the paper during the printing process, allowing the printed patterns and text to be accurately aligned. This greatly avoids common printing problems such as misregistration, blurring, misalignment, and ghosting, significantly improving the clarity of the printed matter. The clarity and accuracy significantly improve product quality. During the movement of the positioning plate 11, the slider 12 connected to it also moves synchronously. The slider 12, in cooperation with a specific groove structure, can provide good support and guidance for the positioning plate 11, thereby greatly improving the stability of the positioning plate 11 during movement and ensuring the accuracy and reliability of the positioning process. When the paper has finished printing on one side and needs to be transferred to the other side for subsequent operations, the electric push rod 13 is activated. The drive end of the electric push rod 13 extends or retracts, driving the moving plate 14 connected to it to move smoothly. The movement of the moving plate 14 then drives the rotating roller 15 to move to the appropriate position. With the cooperation of the two rotating rollers 15, the paper can be firmly fixed and, without detaching, the paper can be flipped over as the equipment continues to operate, preparing for the printing on the other side of the paper.

[0025] Reference Figure 1 and Figure 4 The rotating assembly includes support plates 20 fixedly connected to both sides of the top of the base plate 1. A support platform 16 is fixedly connected to the top of the base plate 1. A second motor 17 is fixedly connected to the front end of the support platform 16. The drive end of the second motor 17 passes through the support platform 16 and is fixedly connected to a rotating shaft 18. The rotating shaft 18 is connected to a connecting ring 22 through the driving assembly. The opposite ends of the fixed frame 2 are fixedly connected to the inner wall of the connecting ring 22. The outer wall of the rotating shaft 18 is rotatably connected to the inner wall of the support platform 16. The outer walls of the connecting ring 22 are slidably connected to the inner wall of the support plate 20. The driving assembly includes gears 19 located on both sides of the outer wall of the rotating shaft 18 and a toothed ring 21 located on the outer wall of the connecting ring 22. The gears 19 and the toothed ring 21 are meshed together.

[0026] Specifically, when the paper printing process reaches the stage where the paper needs to be flipped, the second motor 17 starts operating. After the drive end of the second motor 17 starts, it quickly drives the closely connected rotating shaft 18 to rotate. As the rotating shaft 18 rotates, the gear 19, which is mounted coaxially with it, also starts operating synchronously. The teeth of the gear 19 precisely mesh with the gear ring 21. Driven by the continuous rotation of the gear 19, the gear ring 21 begins to rotate smoothly. The gear ring 21 is also firmly connected to the connecting ring 22, causing the connecting ring 22 to begin circular motion under the drive of the gear ring 21. Because the paper and the connecting ring 22 are tightly connected through a specific fixing method, the rotation of the connecting ring 22 can drive the paper to rotate together. In this way, the paper can be flipped from the currently printed section... The paper is smoothly flipped to the other side. The entire flipping process is completed automatically by this series of closely coordinated mechanical components without manual intervention. This not only greatly saves labor costs and frees operators from tedious manual flipping work, allowing them to devote their energy to more valuable tasks, but also significantly reduces the errors and uncertainties that may be caused by manual operation. When flipping manually, due to factors such as human strength and attention, it is difficult to make the force and angle of each flip completely consistent, which can easily lead to problems such as positional deviations of the paper in subsequent printing. However, thanks to its precise mechanical design, this mechanism can stably and accurately complete the paper flipping action, providing a stable and reliable paper positioning foundation for subsequent printing processes, and effectively ensuring the efficient and accurate execution of printing processing.

[0027] Working principle: When positioning is required, the first motor 5 is started, causing its drive end to rotate, which in turn drives the worm gear 6 to rotate. The worm gear 6 then drives the worm wheel 7, which in turn drives the turntable 8. The turntable 8's rotation pulls the pull plate 9, which in turn moves the slide table 10. The slide table 10, in turn, moves the positioning plate 11 to position the paper, thus ensuring accurate alignment of the printed pattern and text. This effectively avoids problems such as misregistration, blurring, misalignment, and ghosting, improving the clarity and accuracy of the printed materials and enhancing product quality. The movement of the positioning plate 11 also moves the slider 12, which improves the stability of the positioning plate 11 during movement. When transferring the paper to the other side... The electric push rod 13 is activated, causing its drive end to move the moving plate 14. As the moving plate 14 moves, it drives the rotating roller 15 to move. When the two rotating rollers 15 cooperate, they fix the paper. When flipping is required, the second motor 17 is activated, causing its drive end to rotate, which in turn drives the rotating shaft 18 to rotate. As the rotating shaft 18 rotates, it drives the gear 19 to rotate. As the gear 19 rotates, it drives the gear ring 21 to rotate. As the gear ring 21 rotates, it drives the connecting ring 22 to rotate. As the connecting ring 22 rotates, it drives the paper to rotate. This allows the paper to be automatically flipped from one side to the other without manual intervention, saving a lot of manpower, improving production efficiency, and reducing errors and uncertainties caused by manual operation.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
