Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figures 1-3 This utility model provides an embodiment of a pressure equalization adjustment device for a printing press, comprising a fixed frame 1, a fixed block 2 fixedly connected to the upper surface of the fixed frame 1, a hydraulic press 3 fixedly connected inside both the fixed frame 1 and the fixed block 2, a sliding block 4 fixedly connected to the output end of the hydraulic press 3, a slide rail 5 slidably connected to the outer wall of the sliding block 4, the outer wall of the slide rail 5 fixedly connected to the inside of the fixed frame 1, a fixed rod 6 fixedly connected to the outer wall of the sliding block 4, a rack 7 fixedly connected to the outer wall of the fixed rod 6, a gear 8 meshing with the tooth end of the rack 7, a limit post 9 rotatably connected inside the gear 8, the outer wall of the limit post 9 fixedly connected to the inside of the fixed frame 1, and a roller assembly provided on the outer wall of the sliding block 4, the roller assembly being used for ink transfer and pressure application.
[0024] Specifically, the fixed frame 1 and the fixed block 2 provide fixed support for the hydraulic press 3. The hydraulic press 3 pushes the sliding block 4 to slide on the outer wall of the slide rail 5. The fixed frame 1 provides fixed support for the slide rail 5. The sliding block 4 then drives the fixed rod 6, which in turn drives the rack 7 to move. The fixed rod 6 connects the rack 7 and the sliding block 4. The rack 7 drives the gear 8 to rotate on the outer wall of the limiting post 9. The fixed frame 1 provides fixed support for the limiting post 9. The sliding block 4 then drives the fixed post 10, which in turn drives the roller body 11 to adjust, thereby changing the pressure between the rollers.
[0025] Reference Figure 1 and Figure 2 The roller assembly includes a fixed column 10, the outer wall of which is fixedly connected to the outer wall of the sliding block 4, and the outer wall of the fixed column 10 is rotatably connected to the roller body 11.
[0026] Specifically, the sliding block 4 provides fixed support for the fixed column 10, while the roller body 11 transmits ink and applies pressure.
[0027] Reference Figure 1 , Figure 2 and Figure 4 A housing 12 is fixedly connected to the lower surface of the fixed frame 1. A first fixing piece 13 is fixedly connected to the outer wall of the housing 12. A first limiting ring 14 is fixedly connected to the inside of the first fixing piece 13. A limiting rod 15 is rotatably connected to the inside of the first limiting ring 14. A handle 19 is fixedly connected to the outer wall of the limiting rod 15. A sliding groove 16 is opened inside the first limiting ring 14. The outer wall of the limiting rod 15 is rotatably connected to the inner wall of the sliding groove 16. A second fixing piece 17 is slidably connected to the outer wall of the first fixing piece 13. A detector body 20 is fixedly connected to the outer wall of the second fixing piece 17. A second limiting ring 18 is fixedly connected to the inside of the second fixing piece 17. The outer wall of the limiting rod 15 is rotatably connected to the inside of the second limiting ring 18.
[0028] Specifically, by driving the second fixing plate 17 and the detector body 20 to mate with the first fixing plate 13, the handle 19 is driven to drive the limiting rod 15 to slide inside the second limiting ring 18 and the first limiting ring 14. By rotating the handle 19, the limiting rod 15 is driven to rotate through the sliding groove 16 opened in the first limiting ring 14, thereby limiting the limiting rod 15. This fixes the second fixing plate 17 and the detector body 20 to the outer wall of the first fixing plate 13. The detector body 20 monitors the pressure between the rollers in real time. The housing 12 provides fixed support for the first fixing plate 13. The sliding grooves opened inside the first limiting ring 14 and the second limiting ring 18 limit the limiting rod 15.
[0029] Working principle: When the device is needed, the second fixing plate 17 and the detector body 20 are driven to align with the first fixing plate 13. Then, by driving the handle 19, the limiting rod 15 slides inside the second limiting ring 18 and the first limiting ring 14. Rotating the handle 19 causes the limiting rod 15 to rotate, thus limiting the limiting rod 15 in the sliding groove 16 of the first limiting ring 14. This fixes the second fixing plate 17 and the detector body 20 to the outer wall of the first fixing plate 13. The detector body 20 monitors the pressure between the rollers in real time, thereby activating the hydraulic press 3 inside the fixing frame 1 and the fixing block 2. The hydraulic press 3 pushes the sliding block 4 to slide on the outer wall of the slide rail 5, thereby driving the... The fixed rod 6 drives the rack 7 to move, which in turn drives the gear 8 to rotate on the outer wall of the limiting post 9. This, in turn, drives the fixed post 10 via the sliding block 4, which in turn drives the roller body 11 to adjust. This allows for changes in the pressure between the rollers to adapt to variations in paper thickness, ink type, and printing speed. This device not only adapts to printing materials of different thicknesses, textures, and absorbencies, improving the flexibility and applicability of the printing press, but also ensures that the ink on the printing plate is transferred evenly and clearly to the substrate, avoiding problems such as incomplete or unclear halftone dots, pale ink, and distorted images. Furthermore, it allows for the rapid installation of a detector to monitor the pressure changes between the rollers in real time, helping to improve adjustment accuracy and ensure the stability and consistency of printing pressure.
