[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. 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 printing press paper feeding path offset correction device, comprising a housing 1, a load-bearing frame 2 fixedly connected inside the housing 1, a support plate 3 fixedly connected to the upper surface of the load-bearing frame 2, a paper feeder 4 disposed inside the housing 1, the outer wall of the paper feeder 4 rotatably connected to the inside of the support plate 3, a detector 5 disposed on the inner top wall of the housing 1, a conveyor roller 6 disposed inside the load-bearing frame 2, a support base 7 fixedly connected to the upper surface of the load-bearing frame 2, a hydraulic cylinder 8 fixedly connected to the upper surface of the support base 7, a connecting block 9 fixedly connected to the output end of the hydraulic cylinder 8, a slider 10 fixedly connected to the outer wall of the connecting block 9, the outer wall of the slider 10 slidably connected to the inner wall of the support base 7, a correction block 11 fixedly connected to the outer wall of the slider 10, the lower surface of the correction block 11 slidably connected to the upper surface of the load-bearing frame 2, and a driving assembly disposed inside the housing 1 for driving the printing operation.
[0024] Specifically, the outer casing 1 provides fixation for the internal load-bearing frame 2, which in turn supports the paper feeder 4 and the conveyor roller 6. Simultaneously, the support plate 3 also supports the paper feeder 4. When the paper feeder 4 is activated, it uses a suction cup to hold the paper and then rotates to move it forward. The outer wall of the conveyor roller 6 rotates within the middle of the load-bearing frame 2, transporting the paper upon contact. The load-bearing frame 2 provides fixed support for the support base 7, which in turn provides fixed support for the hydraulic cylinder 8. The output end of the hydraulic cylinder 8 fixes the connecting block 9, which in turn fixes the slider. The support base 7 provides support and prevents the slider 10 from shifting, allowing it to move only back and forth within the inner wall of the support base 7. The slider 10 provides fixed support for the correction block 11. The detector 5 detects paper shift. When the detector 5 detects paper shift, it causes the connecting block 9 to move the slider 10 forward within the inner wall of the support base 7 via the output end of the hydraulic cylinder 8. Simultaneously, the slider 10 moves the correction block 11, which moves different distances depending on the paper shift, thus blocking and correcting the paper and ensuring it moves along the prescribed path.
[0025] Reference Figure 2 and Figure 4 The drive assembly includes a motor 12, the outer wall of which is fixedly connected to the inside of the housing 1. A rotating shaft 13 is fixedly installed at the output end of the motor 12. A base plate 14 is fixedly connected to the outer wall of the rotating shaft 13. A limit ring 15 is slidably connected to the inner wall of the base plate 14. A load-bearing plate 16 is fixedly connected to the outer wall of the limit ring 15. The outer wall of the rotating shaft 13 is rotatably connected to the inside of the load-bearing plate 16.
[0026] Specifically, the outer casing 1 provides fixed support for the motor 12 and the load-bearing plate 16, the load-bearing plate 16 provides support for the rotating shaft 13, the rotating shaft 13 provides fixed support for the base plate 14, and the limiting ring 15 provides support and limits the offset of the base plate 14, so that the base plate 14 can only rotate on the outer wall of the limiting ring 15. The load-bearing plate 16 provides fixed support for the limiting ring 15. When the motor 12 is started, the motor 12 will drive the rotating shaft 13 to rotate, and the rotation of the rotating shaft 13 will drive the base plate 14 to rotate, and the base plate 14 will slide on the outer wall of the limiting ring 15.
[0027] Reference Figure 1 and Figure 4 A support block 17 is rotatably connected inside the base plate 14. A hydraulic cylinder 18 is fixedly connected to the upper surface of the support block 17. A connecting frame 19 is rotatably connected to the output end of the hydraulic cylinder 18. A placement block 20 is rotatably connected to the outer wall of the connecting frame 19. The bottom of the placement block 20 is fixedly connected to the upper surface of the base plate 14. A printing shaft 22 is slidably connected to the inner wall of the placement block 20. A clamping block 21 is fixedly connected to the outer wall of the connecting frame 19. The inner wall of the clamping block 21 is slidably connected to the outer wall of the printing shaft 22.
[0028] Specifically, the base plate 14 supports the support block 17, supports and fixes the placement block 20, the placement block 20 supports the printing shaft 22, the support block 17 fixes the hydraulic cylinder 18, the output end of the hydraulic cylinder 18 and the placement block 20 support the connecting frame 19, and the connecting frame 19 fixes the clamping block 21. When the output end of the hydraulic cylinder 18 moves downward, it causes the support block 17 to rotate inside the base plate 14 and drives the connecting frame 19 to rotate outward inside the placement block 20. At the same time, when the output end of the hydraulic cylinder 18 moves upward, it causes the connecting frame 19 to drive the clamping block 21 to move inward and clamp and fix the printing shaft 22, achieving the effect of quick replacement and disassembly.
[0029] Reference Figure 1 and Figure 2 A cover 23 is rotatably connected to the upper left side surface of the outer casing 1, and a paper outlet 24 is provided on the outer left side wall of the outer casing 1.
[0030] Specifically, the outer shell 1 provides support for the cover 23. Opening the cover 23 facilitates the removal and replacement of the printing shaft 22. After printing is completed, the paper will exit from the paper outlet 24.
[0031] Working principle: When the device is needed, the printing paper is placed on the support frame 2, and then the paper feeder 4 is started. The paper feeder 4 moves the printing paper forward through the suction cup. Then, the conveyor roller 6 inside the support frame 2 is started, and the conveyor roller 6 transports the printing paper. When the detector 5 detects paper deviation, the hydraulic cylinder 8 drives the slider 10 to move forward on the inner wall of the support 7 through the connecting block 9. When the slider 10 moves forward, it drives the correction block 11 to move forward on the upper surface of the support frame 2. At the same time, the hydraulic cylinder 8 can precisely control the extension and retraction length of each correction block 11, and perform blocking and correction work on the paper, so that the paper moves according to the set path. When the printing shaft 22 needs to be replaced, the output end of the hydraulic cylinder 18 moves downward and drives the connecting frame 19 to move outward. When the connecting frame 19 moves outward, it rotates on the inner wall of the placement block 20, causing the clamping block 21 to move outward. Then, the printing shaft 22 is placed on the inner wall of the placement block 20. The output end of the hydraulic cylinder 18 then moves the connecting frame 19 upward, causing the clamping block 21 to clamp and fix the printing shaft 22, achieving a better effect of quick disassembly. Then, the motor 12 is started, which drives the rotating shaft 13 to rotate the base plate 14 on the outer wall of the limiting ring 15, thereby achieving the printing operation. This device can not only control the extension and retraction length of each correction block 11 to specifically block and correct the offset paper, but also adapt to the correction requirements of different paper widths, improving the accuracy and flexibility of correction. At the same time, it can also quickly replace and disassemble the printing shaft 22, improving the printing efficiency.
[0032] 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.
