Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a printing press conveying device. Background Technology

[0002] A printing press is a mechanical device that presses the ink-absorbing surface onto the media surface. As one of the most frequently used pieces of equipment in a printing plant, printing presses have the advantages of high automation, fast printing speed, and good product quality. The invention and development of printing presses have played an important role in the dissemination of human civilization and culture.

[0003] A search revealed a patent, CN221318481U, which discloses a conveying device for a printing press. This adjusting device comprises a fixed plate, a sleeve, a limiting rod, a spring, a moving rod, a sliding block, a limiting stop block, a connecting ring, a rotating shaft, and a fixed roller. The fixed plate is fixedly installed inside a support frame, the sleeve is fixedly installed on the surface of the fixed plate, the limiting rod is fixedly installed on the surface of the fixed plate, the spring is fixedly installed inside the sleeve, the moving rod is slidably installed inside the sleeve, the sliding block is fixedly installed on the side of the moving rod, and the limiting stop block is fixedly installed at the other end where the limiting rod and the fixed plate connect. This conveying device, by incorporating an adjusting mechanism, allows the fixed roller to automatically adjust its force when the paper transport direction changes, effectively preventing paper tearing. Combined with the anti-slip sleeve, it prevents paper slippage, thus avoiding impact on subsequent printing results.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document uses a spring to constantly exert a pushing force on the push rod, thereby causing the gap between the two fixed rollers to adaptively adjust with the thickness of the paper. However, in reality, printing presses also require the paper to maintain tension during the paper transport process. While the aforementioned comparative document can adaptively apply pressure to the paper, its tensioning effect during transport is poor, which may cause wrinkles in the paper during transport. Therefore, there is an urgent need in the art to improve the conveying device of printing presses to overcome the shortcomings of the prior art. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1

[0029] Please see Figures 1-6A printing press conveying device includes a support base 1, with two symmetrical support frames 2 and support plates 5 located on the upper surface of the support base 1. A fixed drive roller 3 is rotatably connected between the inner walls of the support frames 2. A movable pressure roller 4 for pressing a paper body 7 is provided between the inner walls of the support frames 2. A tension roller 6 for tensioning the paper body 7 is provided between the two support plates 5. A first damper 8 and a first spring 9 are provided inside the support frames 2 for connecting to both ends of the movable pressure roller 4. A second damper 8 and a first spring 9 are provided inside the support plates 5 for connecting to both ends of the tension roller 6. Two dampers 10 and a second spring 11 are provided. The support frame 2 is provided with a first adjustment unit 12 for adjusting the position of the moving pressure roller 4. The support plate 5 is provided with a second adjustment unit 13 for adjusting the position of the tension roller 6. Several sets of positioning units 14 for positioning the paper body 7 are provided on the opposite sides of the two support frames 2. A drive motor 31 for driving the fixed drive roller 3 to rotate is fixedly installed on one side of the support frame 2. The two ends of the moving pressure roller 4 are rotatably connected to the first moving seats 15. The opposite side walls inside the support frame 2 are provided with openings that are adapted to the first moving seats 15. The first moving groove 16, the first damper 8 and the first spring 9 are all fixedly connected to the first moving seat 15. The first adjusting unit 12 includes a first moving plate 17 fixedly connected to the first damper 8 and the first spring 9 away from the first moving seat 15. The upper part of the support frame 2 is threaded with a first adjusting bolt 18, one end of which is rotatably connected to the upper surface of the first moving plate 17. The side of the first adjusting bolt 18 is threaded with a first limiting nut 19 for limiting. The two ends of the tension roller 6 are rotatably connected to the second moving seat 20. The side of the support plate 5 is provided with a second moving groove 22 adapted to the second moving seat 20. One end of the second damper 10 and the second spring 11 is fixedly connected to one side of the second moving seat 20. The second adjusting unit 13 includes a second moving plate 21 slidably connected in the second moving groove 22. One end of the second damper 10 and the second spring 11 is fixedly installed on one side of the second moving plate 21. The upper end of the support plate 5 is threaded with a second adjusting bolt 23, one end of which is rotatably connected to the second moving plate 21. The side of the second adjusting bolt 23 is threaded with a second limiting nut 24 for limiting.

[0030] Specific implementation method in this embodiment: When the printing press needs to transport the paper body 7, the paper body 7 is sequentially transported as follows: Figure 1The paper body 7 is pressed against the tension roller 4 by the tension of the first damper 8 and the first spring 9. The second damper 10 and the second spring 11 exert a downward force on the tension roller 6, further tensioning the paper body 7 and improving its tension during transport, thus preventing wrinkles. When the tension of the paper body 7 needs adjustment, the second adjusting bolt 23 is rotated. This rotation causes the second moving plate 21 to move downwards in the second moving groove 22, which in turn moves the second damper 10 and the second spring 11 downwards, pushing the second moving seat 20 downwards in the second moving groove 22. Since the positions of the two fixed drive rollers 3 are fixed, the tension of the paper body 7 is increased. Then, the second limiting nut 24 is tightened to limit and fix the position of the second adjusting bolt 23. When transporting paper bodies 7 of different thicknesses, the first adjusting bolt 18 is rotated. When the first moving plate 17 moves within the first moving groove 16, the first moving plate 17 drives the first moving seat 15 to move within the first moving groove 16 via the first damper 8 and the first spring 9, thereby adjusting the distance between the fixed drive roller 3 and the moving pressing roller 4. After adjusting the distance between the fixed drive roller 3 and the moving pressing roller 4, the first limit nut 19 is tightened to limit and fix the position of the first adjusting bolt 18. This allows for the pressing and conveying of paper bodies 7 of different thicknesses, improving the applicability of the overall device. In addition, when conveying the paper body 7, the drive motor 31 is started. The output end of the drive motor 31 drives the fixed drive roller 3 to rotate and convey the paper body 7. It should be noted that the first damper 8 and the second damper 10 mentioned above are existing damping rods with damping effect. They work with the first spring 9 and the second spring 11 to provide tension and prevent the moving pressing roller 4 and the tensioning roller 6 from jumping violently due to the action of the first spring 9 and the second spring 11 during the conveying of the paper body 7, thereby maintaining continuous pressing and tension on the paper body 7.

[0031] The drive motor 31 mentioned above can be purchased from the market. It is a mature technology that has been fully disclosed, so it will not be repeated in the specification. The drive motor 31 is equipped with a power connection line, and it is electrically connected to the external main controller and 220V phase voltage (or 380V line voltage) through the power connection line. The main controller can be a conventional known device such as a computer that plays a control role.

[0032] Example 2

[0033] Please see Figure 1 , Figure 2 and Figure 5This embodiment includes the above embodiment, and further includes: the positioning unit 14 includes several fixed plates 25 fixedly connected to one side of the support frame 2, a third adjusting bolt 26 is threaded through and threaded on the fixed plate 25, one end of the third adjusting bolt 26 is rotatably connected to a U-shaped fixing frame 27, a positioning roller 28 is provided between the inner side walls of the fixing frame 27 located on the side of the paper body 7, a third limiting nut 29 for limiting is threaded on the side of the third adjusting bolt 26, and a limiting rod 30 that penetrates the fixed plate 25 is fixedly connected to one side of the fixing frame 27.

[0034] In this embodiment, the following is a specific implementation method: When conveying paper bodies 7 of different widths, the third adjusting bolt 26 is rotated. When the third adjusting bolt 26 rotates, it drives the fixed frame 27 to move, thereby adjusting the distance between the two corresponding positioning rollers 28. When the fixed frame 27 moves, the limiting rod 30 moves on the fixed plate 25, and the limiting rod 30 limits the position of the fixed frame 27. After adjusting the distance between the two positioning rollers 28 to match the width of the paper body 7, the third limiting nut 29 is tightened to limit the position of the third adjusting bolt 26. The positioning rollers 28 can prevent the paper body 7 from deviating during conveying, and the distance between the two positioning rollers 28 is adjustable, which is suitable for conveying paper bodies 7 of different widths.
