Description

Technical Field

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

[0002] The printing press web guiding device is a core auxiliary equipment for ensuring printing quality. It focuses on lateral web guiding and tension balance during the paper printing process, adapts to various paper printing substrates, and can be directly integrated into the printing press feeding unit. Its core advantages are simple structure, precise adjustment, and stable operation. It can effectively solve the pain points of low efficiency and poor accuracy of manual web guiding. It is mainly composed of frame components, drive unit, guide mechanism, and auxiliary components. When the web guiding device is working, the paper is transmitted through two sets of tension guide rollers on the moving frame. When the paper is laterally offset or the tension at both ends is uneven, the device triggers the cylinder to act through preset detection logic. The piston rod extends and retracts, driving the moving frame to precisely offset along the guide shaft. The guide mechanism and bearings work together to ensure the smooth operation of the moving frame, quickly adjusting the force balance at both ends of the paper and restoring the paper to the preset printing baseline. Its core function is to eliminate the problems of offset and uneven tension during paper feeding, avoid quality defects such as misregistration and missing edge printing, improve the printing yield, reduce paper waste, and replace manual web guiding, thereby improving the automation level and operating efficiency of the printing production line. Since different paper sizes require different web guiding width ranges, it is necessary to perform web guiding adjustment operations.

[0003] In related technologies, during the use of the correction device, the L-shaped correction plate frame is mainly used to restrict and prevent the paper from shifting, thereby ensuring the positional stability of the paper during the printing process.

[0004] However, in the current use of the web guiding device, due to the limited range of motion of the web guiding plate frame and the limited inner width of the web guiding plate, when the paper size is small, it is very easy for the inner width of the web guiding plate to be unable to effectively contact the paper to restrict the web guiding, which affects the flexibility and adaptability of the web guiding device.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, 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, 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 scope of protection of this utility model.

[0020] Reference Figures 1-4This utility model provides a technical solution: a correction device for a printing press, including a base 1 and a correction adjustment mechanism. The base 1 has two recesses 2 on both sides of its top. A correction plate 3 is installed inside the recesses 2. A correction width adjustment medium can be formed inside the correction plate 3 so that the user can adjust the correction width range inside the correction plate 3 according to the actual size of the paper. This avoids the situation where the correction width of the correction plate 3 is difficult to adjust, making it difficult for the correction plate 3 to contact the paper for correction. Therefore, the flexibility and adaptability of the correction plate 3 are improved.

[0021] Reference Figures 1-4 In a preferred embodiment, the correction adjustment mechanism includes an adjustment frame 4, which is movably connected to the outer side of the top of the correction plate 3. An adjustment plate 5 located inside the correction plate 3 is movably connected to the bottom of the adjustment frame 4. Fixing holes 6 are located on both sides of the outer side of the adjustment frame 4, and fixing bolts 7, threadedly connected to the correction plate 3, are movably connected inside the fixing holes 6. The adjustment connection mechanism is located inside the bottom of the adjustment frame 4. Based on the actual size of the external paper limiting the correction requirements, the adjustment plate 5 is moved inward by hand to adjust the correction width range inside the correction plate 3, thus allowing the adjustment plate 5 to cooperate with the adjustment frame 4 for correction. The plate 3 restricts and corrects the deviation of the external paper. The adjustment and connection mechanism includes a connecting groove 8, a connecting seat 9, and a connecting port 10. The connecting groove 8 is opened on the inner side of the bottom of the adjustment frame 4. The connecting seat 9 is movably connected to the inside of the connecting groove 8. The bottom of the connecting seat 9 is fixedly connected to the top of the adjustment plate 5. The connecting port 10 is opened on the top of the inner wall of the connecting groove 8. It can adjust the connection between the adjustment plate 5 and the adjustment frame 4, so that the user can move the adjustment plate 5 laterally to make adjustments. This avoids the adjustment plate 5 from shifting or even separating from the adjustment frame 4 during use, thus improving the connection effect between the adjustment plate 5 and the adjustment frame 4.

[0022] Reference Figures 2-4 In a preferred embodiment, a positioning frame 11 is movably connected to the top of the connection port 10, and positioning columns 12 are fixedly connected to both sides of the top of the adjustment frame 4. The top of the positioning column 12 extends through to the top of the positioning frame 11, which allows for the insertion and positioning of the adjusted plate 5 and the adjustment frame 4 after adjustment, thus avoiding the difficulty in positioning the adjustment plate 5 during use and improving the convenience of adjusting and positioning the adjustment plate 5. A lifting frame 13 located outside the positioning frame 11 is movably connected to the top of the adjustment frame 4, and a lifting cover 14 is movably connected to the top of the lifting frame 13, which allows for the lifting and connecting of the positioning frame 11 and the adjustment frame 4 to prevent deviation and separation, thus avoiding the separation of the positioning frame 11 from the adjustment frame 4 during use and improving the connection effect between the positioning frame 11 and the adjustment frame 4.

[0023] Reference Figures 2-4In a preferred embodiment, screw cylinders 15 are fixedly connected to the top of both sides of the lifting frame 13. Bolts 16, which extend through to the top of the lifting cover 14, are connected to the screw cylinders 15. This allows for the connection and fixation between the lifting cover 14 and the lifting frame 13, thus improving the connection effect between the lifting cover 14 and the lifting frame 13. A screw groove 17 is provided on the top of the connecting seat 9. A stud 18 is connected to the screw groove 17. The top of the stud 18 is fixedly connected to the bottom of the lifting frame 13. This allows for the installation and connection between the lifting frame 13 and the connecting seat 9, avoiding the situation where the lifting frame 13 is difficult to install and connect with the connecting seat 9 during use. This improves the ease of installation and connection between the lifting frame 13 and the connecting seat 9.

[0024] Reference Figures 2-4 In a preferred embodiment, a spring 19 is provided inside the lifting frame 13. One end of the spring 19 is connected to the bottom of the lifting cover 14, and the other end of the spring 19 is connected to the top of the positioning frame 11. This can apply a downward pushing force to the positioning frame 11, preventing the positioning frame 11 from easily separating from the positioning column 12 during operation. This improves the positioning stability of the positioning frame 11. A moving hole 20 is provided on the top of the lifting cover 14. A moving handle 21 located inside the spring 19 is movably connected inside the moving hole 20. The bottom of the moving handle 21 is fixedly connected to the top of the positioning frame 11. This provides a medium for the user to move the positioning frame 11 to rise and separate from the positioning column 12, thus improving the ease of operation of moving the positioning frame 11 upward.

[0025] Specifically, the working process or principle of the correction device for this printing press is as follows: During use, the hand-held moving handle 21, in conjunction with the moving hole 20, applies an upward pulling force to the positioning frame 11, causing the positioning frame 11 to separate from the positioning post 12. At this time, the spring 19 contracts under the influence of the upward moving force of the positioning frame 11, preparing for the subsequent application of a downward pushing force to the positioning frame 11. During this process, the screw barrel 15, in conjunction with the bolt 16, connects and tightens the lifting cover 14 and the lifting frame 13. Simultaneously, the stud 18, in conjunction with the screw groove 17, connects and tightens the lifting frame 13 and the connecting seat 9 to prevent separation. At the same time, the fixing bolt 7, in conjunction with the fixing hole 6, connects and tightens the adjusting frame 4 and the correction plate 3 to prevent separation. Subsequently, the moving handle 21, in conjunction with the lifting frame 13 and the stud 18, applies an inward moving force to the connecting seat 9, causing the connecting seat 9 to move the adjusting plate 5 inward, thus adjusting the correction width range between the correction plates 3. During the adjustment process, the connecting seat 9 moves within the connecting groove 8, enabling it to connect the adjusting plate 5 and the adjusting frame 4 and prevent deviation. Simultaneously, the stud 18 moves with the connecting seat 9 and the lifting frame 13 within the connecting port 10, ensuring smooth movement of the connecting seat 9 in conjunction with the adjusting plate 5. After the adjusting plate 5 is adjusted, the moving handle 21 is used to move the positioning frame 11 downwards, causing the positioning pin 12 to pass through the opening at the top of the positioning frame 11. This allows the positioning pin 12 to engage with the positioning frame 11, and through the lifting frame 13, the stud 18, and the connecting seat 9, to perform the insertion and positioning work between the adjusted adjusting plate 5 and the adjusting frame 4. At the same time, the retracting spring 19, in conjunction with the lifting cover 14, applies a downward pushing force to the positioning frame 11, ensuring the stability of the insertion and positioning of the positioning frame 11 and the positioning pin 12. This allows the adjusting plate 5 to work with the adjusting frame 4 to change the correction width range inside the correction plate 3, thus limiting and correcting the deviation of external paper.

[0026] It should be noted that the base 1, the sink 2 and the correction plate 3 are all existing devices or equipment, or devices or equipment that can be implemented by existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
