[0002] Printing is a technique for copying information, such as text and images, onto various surfaces. It plays a vital role in modern society and is widely used in publishing, packaging, advertising, commercial paperwork, and other fields. Types of printing include: Letterpress printing: One of the earliest printing methods, letterpress printing involves applying ink to a raised plate and then transferring the ink to a substrate such as paper through pressure. Lithographic printing: One of the most widely used printing methods today, it utilizes the principle that oil and water do not mix. Ink and water are applied to different areas of the plate and then transferred to the substrate using pressure. Gravure printing: A highly precise printing method, gravure printing involves filling a concave plate with ink and then transferring the ink to the substrate using pressure. Screen printing: A specialized printing method, screen printing transfers ink to the substrate by squeezing it through the hollowed-out areas of the screen plate.

[0003] In order to improve production efficiency during the printing process, a printing device is often set in a printing production line to print on the surface of the printed matter on a conveyor belt. However, during the process of the printed matter being conveyed on the conveyor belt surface, a certain deviation will occur, resulting in the printed pattern being skewed when the printed matter is printed. Therefore, a correction device is required to correct the skewed printed matter. For this purpose, a correction device for printed matter is proposed. Utility Model Content

[0021] The present invention is further described in detail below with reference to the embodiments: Example

[0022] like Figure 1-4 As shown, the utility model provides a correction device for printed materials, including a printed material conveyor belt 1, a printed material 2 overlapped on the surface of the printed material conveyor belt 1, a lifting mechanism 3 is bolted to both sides of the printed material conveyor belt 1, a longitudinal correction mechanism 4 is fixedly connected to one side of the lifting mechanism 3, and a transverse correction mechanism 5 is fixedly connected to the surface of the lifting mechanism 3.

[0023] In this embodiment, the printed matter 2 moving along the printed matter conveyor belt 1 is blocked by the longitudinal correcting plate 47, and the longitudinal position of the printed matter 2 is corrected. Then, the two sets of second cylinders 53 are started synchronously, so that the transverse correcting plates 54 on both sides of the printed matter 2 are synchronously close to the printed matter, pushing the printed matter 2 to move and correcting the transverse deviation of the printed matter 2. After the correction is completed, the second cylinder 53 is started synchronously again to separate the transverse correcting plates 54 from the surface of the printed matter 2. Then, the first cylinder 32 pushes the lifting member 33 to slide upward along the guide rod 34, thereby moving the longitudinal correcting plate 47 upward, so that the corrected printed matter 2 can continue to move forward along the printed matter conveyor belt 1 for printing, thereby avoiding the printed matter 2 from being skewed before printing and keeping the printed pattern regular. Example

[0024] like Figure 1-4As shown, on the basis of embodiment 1, the utility model provides a technical solution: preferably, the lifting mechanism 3 includes a mounting member 31, one side of the mounting member 31 is bolted to both sides of the printed matter conveyor belt 1, the middle part of the top of the mounting member 31 is fixedly connected to the first cylinder 32, the output end of the first cylinder 32 is fixedly connected to the lifting member 33, the two ends of the lifting member 33 are internally overlapped with guide rods 34, the lower end of the guide rod 34 is fixedly connected to the two ends of the top of the mounting member 31, the longitudinal deviation correcting mechanism 4 includes a slide rail 41, one side of the slide rail 41 is connected to the lifting member 33, and the lifting member 33 is fixedly connected to the output end of the first cylinder 32. One side of the lowering piece 33 is fixedly connected, the surface of the slide rail 41 is provided with anti-slip teeth 42, the surface of the slide rail 41 is slidably connected with a sliding sleeve 43, one side of the sliding sleeve 43 is threadedly connected with an adjusting bolt 44, one end of the adjusting bolt 44 is against the surface of the anti-slip teeth 42, and the bottom of the sliding sleeve 43 is fixedly connected with a first support rod 45, the lower end of the first support rod 45 is fixedly connected with a second support rod 46, one end of the second support rod 46 is fixedly connected with a longitudinal correcting plate 47, and the side of the longitudinal correcting plate 47 close to the second support rod 46 is fixedly connected with a first anti-collision strip 48.

[0025] In this embodiment, when correcting the printed matter 2, the sliding sleeve 43 is pushed to slide along the slide rail 41 according to the size of the printed matter 2, and the longitudinal correction plate 47 is moved to a suitable position. Then, the adjusting bolt 44 is rotated so that one end of the adjusting bolt 44 is tightly against the anti-slip teeth 42 on the surface of the slide rail 41 to fix the sliding sleeve 43. After the fixing is completed, correction is performed. Example

[0026] like Figure 1-4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the lateral correction mechanism 5 includes a fixing member 52, the top of the fixing member 52 is fixedly connected to the third support rod 51, the top of the third support rod 51 is fixedly connected to the bottom of the lifting member 33, one side of the fixing member 52 is fixedly connected to the second cylinder 53, the output end of the second cylinder 53 is fixedly connected to the lateral correction plate 54, and the side of the lateral correction plate 54 away from the second cylinder 53 is fixedly connected to the second anti-collision strip 55.

[0027] In this embodiment, the first anti-collision strip 48 and the second anti-collision strip 55 can also protect the printed matter 2 to prevent the transverse correction plate 54 and the longitudinal correction plate 47 from leaving indentations on the surface of the printed matter 2, making it easier to use.

[0028] The following is a detailed description of the working principle of the correction device for printed products.

[0029] like Figure 1-4As shown, when correcting the deviation of the printed product 2, the sliding sleeve 43 is pushed to slide along the slide rail 41 according to the size of the printed product 2. After the longitudinal correction plate 47 is moved to the appropriate position, the adjusting bolt 44 is rotated to make one end of the adjusting bolt 44 tightly contact the anti-slip teeth 42 on the surface of the slide rail 41 to fix the sliding sleeve 43. After the fixation is completed, correction is performed to block the printed product 2 moving along the printed product conveyor belt 1 through the longitudinal correction plate 47 to correct the longitudinal position of the printed product 2. Subsequently, the two sets of second cylinders 53 are synchronously started to make the transverse correction plates 54 on both sides of the printed product 2 synchronously approach the printed product, push the printed product 2 to move, and produce the printed product 2. The generated lateral deviation is corrected. After the correction is completed, the second cylinder 53 is started again synchronously to separate the lateral correcting plate 54 from the surface of the printed matter 2. Then the first cylinder 32 pushes the lifting member 33 to slide upward along the guide rod 34, thereby moving the longitudinal correcting plate 47 upward, so that the corrected printed matter 2 can continue to move forward along the printed matter conveyor belt 1 for printing, avoiding the printed matter 2 from being skewed before printing and keeping the printed pattern regular. At the same time, the setting of the first anti-collision strip 48 and the second anti-collision strip 55 can also protect the printed matter 2, avoiding the lateral correcting plate 54 and the longitudinal correcting plate 47 from leaving indentations on the surface of the printed matter 2, making it more convenient to use.

[0030] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
