[0017] 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.

[0018] Example 1 Please see Figure 1-6 The present invention provides the following technical solution: a paper feeding mechanism for a lantern outer coating printing machine, including a conveying table 1, an active rotating shaft 4 fixedly installed on the top of the conveying table 1, a rubber roller 5 fixedly installed on the surface of the active rotating shaft 4, a pressing component 2 fixedly installed on one side of the active rotating shaft 4, and a limiting component 3 installed on the inner side of the conveying table 1. The pressing component 2 includes a support plate 27, which is fixedly mounted on the top surface of the conveying table 1. A top plate 21 is fixedly connected to the top of the support plate 27. A cylinder 22 is fixedly installed on the top surface of the top plate 21. A movable plate 25 is connected to the output end of the cylinder 22. A pressing component 26 is installed at the bottom of the movable plate 25. A scale plate 24 is fixedly connected to the top of the movable plate 25. A through hole 23 is opened on the inner side of the top plate 21.

[0019] By adopting the above technical solution, when using the pressing component 2, the cylinder 22 is activated, and the cylinder 22 drives the movable plate 25 to move downward, which in turn drives the pressing component 26 to move downward. The pressing component 26 presses down on the paper, so that the paper can always remain stable during the process of moving, thus improving the stability of paper feeding. By observing the scale lines on the surface of the scale plate 24, the pressing distance of the pressing movable plate 25 can be adjusted, thus improving the accuracy of pressing.

[0020] Specifically, protrusions are fixed to both sides of the movable plate 25, and guide grooves are provided on the inner side of the support plate 27.

[0021] By adopting the above technical solution, when the movable plate 25 moves, the protrusion moves synchronously inside the guide groove, which further improves the stability of the movable plate 25.

[0022] Specifically, the clamping assembly 26 includes a movable cavity 261, which is located at the bottom of the movable plate 25. A sliding plate 263 is movably disposed inside the movable cavity 261. A limiting block 262 is fixedly connected to the top of the sliding plate 263. A spring 264 is fixedly disposed on the top of the limiting block 262. A limiting post 265 is fixedly connected to the top of the movable cavity 261.

[0023] By adopting the above technical solution, when the cylinder 22 pushes the movable plate 25 downward, the slide plate 263 moves downward synchronously. When the slide plate 263 contacts the paper, in order to ensure the stability of the downward pressure, the cylinder 22 can continue to push the movable plate 25 downward. At this time, the spring 264 is under force, and the slide plate 263 is pushed downward synchronously by the force of the spring 264, so that the slide plate 263 can always maintain the downward pressure on the paper, thereby improving the stability of the downward pressure.

[0024] Specifically, a groove is provided at the contact point between the limiting block 262 and the spring 264.

[0025] By adopting the above technical solution, the groove can limit the end of the spring 264 near the limiting block 262, preventing the spring 264 from twisting when subjected to force, thus affecting the normal use of the mechanism.

[0026] In this embodiment, during use: When using the pressing component 2, the cylinder 22 is activated, causing the movable plate 25 to move downwards, simultaneously driving the pressing component 26 downwards. The pressing component 26 presses down on the paper, ensuring its stability during travel and improving paper feeding stability. The pressing distance of the movable plate 25 can be adjusted by observing the scale lines on the scale plate 24, improving pressing accuracy. During the movement of the movable plate 25, the protrusions move synchronously within the guide groove, further enhancing the stability of the movable plate 25. The cylinder 22 pushes... When the movable plate 25 moves downward, the sliding plate 263 moves downward synchronously. When the sliding plate 263 contacts the paper, in order to ensure the stability of the downward pressure, the movable plate 25 can continue to be pushed downward by the cylinder 22. At this time, the spring 264 is under force, and the sliding plate 263 is pushed downward synchronously by the force of the spring 264, so that the sliding plate 263 can always maintain the downward pressure on the paper, which improves the stability of the downward pressure. The groove can limit the end of the spring 264 near the limit block 262, so as to prevent the spring 264 from twisting when under force, which would affect the normal use of the mechanism.

[0027] Example 2 The difference between this embodiment and embodiment 1 is that, specifically, the limiting component 3 includes a mounting groove 31, which is opened on the top of the conveyor table 1. A bidirectional screw 32 is rotatably arranged inside the mounting groove 31. A motor 35 is installed at one end of the bidirectional screw 32. A threaded plate 36 is threadedly connected to the surface of the bidirectional screw 32. A limiting plate 33 is installed on the top of the threaded plate 36. An inclined plate 34 is fixed to the outer end of the limiting plate 33.

[0028] By adopting the above technical solution, when using the limiting component 3, the paper to be conveyed is first placed on the surface of the conveying table 1. Then, the distance between the limiting plates 33 is adjusted according to the size of the paper. During adjustment, the motor 35 is started, and the motor 35 drives the bidirectional screw 32 to rotate inside the mounting groove 31. The screw plate 36 further drives the limiting plates 33 to move closer to each other until the inner sides of the limiting plates 33 on both sides contact the two sides of the paper. This completes the position adjustment of the limiting plates 33. In use, the limiting plates 33 can limit the two ends of the paper, thereby preventing the paper from shifting position during travel and improving the stability of paper feeding.

[0029] Specifically, a mounting ear plate is fixed to the top of the threaded plate 36, and a mounting screw hole is opened on the inner side of the mounting ear plate.

[0030] By adopting the above technical solution, the installation of ear plates and screw holes allows for easy replacement of limit plates 33 of different sizes according to different limit requirements, thereby improving the practicality of the mechanism.

[0031] Specifically, the inner side of the limiting plate 33 is provided with a movable groove, and an inclined block is fixedly installed on the inner side of the movable groove. An installation plate is fixedly connected to one side of the inclined block.

[0032] By adopting the above technical solution, the height of the inclined block can be easily adjusted through the cooperation of the movable groove and the mounting plate. The inclined block can limit the top of the paper, thus enhancing its practicality.

[0033] In this embodiment, when using the limiting component 3, the paper to be conveyed is first placed on the surface of the conveying table 1. Then, the distance between the limiting plates 33 is adjusted according to the size of the paper. During adjustment, the motor 35 is started, and the motor 35 drives the bidirectional screw 32 to rotate inside the mounting groove 31. The screw plate 36 further drives the limiting plates 33 to move closer to each other until the inner sides of the limiting plates 33 on both sides contact the two sides of the paper. This completes the position adjustment of the limiting plates 33. In use, the limiting plates 33 can limit both ends of the paper, thereby preventing the paper from shifting position during travel and improving the stability of paper feeding. The mounting ear plate and mounting screw hole make it easy to replace the limiting plates 33 of different sizes according to different limiting requirements, thereby improving the practicality of the mechanism. The movable groove cooperates with the mounting plate to facilitate the adjustment of the height of the inclined block. The inclined block can limit the top of the paper, enhancing practicality.

[0034] The structure and operating principle of the conveyor table 1, the active rotating shaft 4, and the rubber roller 5 in this utility model have been disclosed in the paper feeding mechanism of the lantern outer coating printing machine disclosed in Chinese Patent Publication No. CN218433921U.

[0035] The working principle and usage process of this utility model are as follows: When using the pressing component 2, the cylinder 22 is activated. The cylinder 22 drives the movable plate 25 to move downward, simultaneously driving the pressing component 26 to move downward. The pressing component 26 presses down on the paper, ensuring that the paper remains stable during its movement and improving the stability of the paper feeding. By observing the scale lines on the surface of the scale plate 24, the pressing distance of the movable plate 25 can be adjusted, improving the accuracy of the pressing. When the movable plate 25 moves, the protrusion moves synchronously inside the guide groove, further improving the stability of the movable plate 25. When the movable plate 25 is pushed downward by cylinder 22, the slide plate 263 moves downward synchronously. When the slide plate 263 contacts the paper, in order to ensure the stability of the downward pressure, the movable plate 25 can continue to be pushed downward by cylinder 22. At this time, the spring 264 is under force, and the slide plate 263 is pushed downward synchronously by the force of the spring 264, so that the slide plate 263 can always maintain the downward pressure on the paper, which improves the stability of the downward pressure. The groove can limit the end of the spring 264 near the limit block 262, so as to prevent the spring 264 from twisting when under force, which would affect the normal use of the mechanism. When using the limiting component 3, first place the paper to be conveyed on the surface of the conveying table 1. Then, adjust the distance between the limiting plates 33 according to the size of the paper. During adjustment, start the motor 35. The motor 35 drives the bidirectional screw 32 to rotate inside the mounting groove 31. Further, the threaded plate 36 drives the limiting plates 33 to move closer to each other until the inner sides of the limiting plates 33 on both sides contact the two sides of the paper. This completes the position adjustment of the limiting plates 33. In use, the limiting plates 33 can limit the two ends of the paper, thereby preventing the paper from shifting position during travel and improving the stability of paper feeding. The mounting ear plate and mounting screw hole make it easy to replace the limiting plates 33 of different sizes according to different limiting requirements, thereby improving the practicality of the mechanism. The movable groove cooperates with the mounting plate to facilitate the adjustment of the height of the inclined block. The inclined block can limit the top of the paper, enhancing practicality.
