Description

Technical Field

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

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms such as plate mounting, inking, printing, and paper feeding. Its working principle is as follows: First, the text and images to be printed are made into a printing plate and mounted on the printing press. Then, ink is applied to the areas on the printing plate with text and images by hand or by the printing press. The ink is then transferred directly or indirectly to paper or other printing substrates, thereby reproducing printed materials identical to the printing plate.

[0003] Four-color printing presses are a type of printing press. When printing different products, four-color printing presses require plate changing operations. Existing printing presses usually have automatic plate changing functions. However, during the plate changing process, the plate adjustment needs to be pre-fixed. The existing pre-fixing components have fixed lateral distances. When using plates of different sizes, it is impossible to pre-fix the lateral position of the plate adjustment, which may lead to plate position deviations during plate loading and reduce the plate loading effect. Therefore, a lateral plate adjustment device for printing presses is proposed to solve the above-mentioned problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a lateral plate-adjusting device for a printing press. This device offers advantages such as the ability to adjust the lateral position of the plate, improving the plate-mounting effect. It solves the problem that four-color printing presses, being a type of printing press, require plate-changing operations when printing different products. While existing printing presses typically have automatic plate-changing functions, the plate needs to be pre-fixed during the plate-changing process. However, existing pre-fixing components have fixed lateral distances, making it impossible to pre-fix the lateral position of the plate when mounting plates of different sizes. This can lead to plate-mounting position deviations and reduced plate-mounting quality.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A horizontal plate adjustment device for a printing press includes a mounting plate, a limiting frame fixedly connected to the rear end of the mounting plate, a limiting component provided on the inner side of the limiting frame, and four limiting components. A moving block is fixedly connected to the front end of the limiting component, and an adjusting plate is fixedly connected to the outer side of the moving block. Two adjusting plates are provided, a limiting bottom frame is fixedly connected to the outer side of the adjusting plate, and a limiting plate is fixedly connected to the outer side of the adjusting plate. A connecting printing plate is movably connected to the top end of the limiting bottom frame, and a snap-fit ​​component is fixedly connected to the inner side of the upper moving block.

[0008] The beneficial effects of this utility model are:

[0009] The printing press's horizontal plate-adjusting device has the advantage of being able to adjust the horizontal position of the plate, thus improving the plate-mounting effect.

[0011] Furthermore, a connecting rod is fixedly connected to the outer side of the moving block, and there are two connecting rods. There are multiple limiting plates, and the multiple limiting plates are evenly distributed on the outer side of the adjusting plate.

[0012] The advantage of adopting the above-mentioned further solution is that the connecting rod can improve the stability of the moving block connection.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the embodiments, by Figure 1-5 The present invention discloses a horizontal plate adjustment device for a printing press. The present invention includes a mounting plate 1, a limiting frame 2 fixedly connected to the rear end of the mounting plate 1, a limiting component 3 provided on the inner side of the limiting frame 2, and four limiting components 3. A moving block 4 is fixedly connected to the front end of the limiting component 3, and two adjusting plates 5 are fixedly connected to the outer side of the moving block 4. A limiting bottom frame 6 is fixedly connected to the outer side of the adjusting plate 5, and a limiting plate 7 is fixedly connected to the outer side of the adjusting plate 5. A connecting printing plate 8 is movably connected to the top end of the limiting bottom frame 6, and a snap-fit ​​component 9 is fixedly connected to the inner side of the upper moving block 4.

[0026] Mounting plate 1 is installed on the outside of the four printing presses.

[0027] Among them, the outer side of the movable block 4 is fixedly connected with a connecting rod 10, and there are two connecting rods 10. There are multiple limiting plates 7, and the multiple limiting plates 7 are evenly distributed on the outer side of the adjusting plate 5.

[0028] The connecting rod 10 can improve the stability of the connection of the moving block 4, and the large number of limiting plates 7 can improve the position restriction of the connecting printed plate 8.

[0029] The limiting component 3 includes a limiting groove 31 formed inside the limiting frame 2. A limiting block 32 is movably connected to the inner side of the limiting groove 31. The limiting block 32 extends to the front end of the mounting plate 1, and the outer side of the limiting block 32 is polished.

[0030] The limiting component 3 can restrict the movement of the moving block 4 to prevent the moving block 4 from shifting position during the movement.

[0031] The snap-fit ​​assembly 9 includes a snap-fit ​​spring 91 fixedly connected to the inner side of the upper moving block 4. The snap-fit ​​spring 91 is fixedly connected to the inner side of the snap-fit ​​spring 91, and the snap-fit ​​plate 92 is fixedly connected to the other end of the snap-fit ​​spring 91. The snap-fit ​​rod 93 is fixedly connected to the outer side of the snap-fit ​​plate 92, and the snap-fit ​​rod 93 extends to the inner side of the limiting frame 2.

[0032] The snap-fit ​​component 9 can restrict the position of the moving block 4.

[0033] The inner side of the limiting frame 2 is provided with a snap-fit ​​groove 11. There are multiple snap-fit ​​grooves 11, which are distributed in a straight line array at equal distances on the inner side of the limiting frame 2. The snap-fit ​​rod 93 extends to the inner side of one of the snap-fit ​​grooves 11. The outer side of the snap-fit ​​plate 92 is fixedly connected to a pull rope 12, and the other end of the pull rope 12 is fixedly connected to a pull ring.

[0034] Pulling rope 12 will move the snap plate 92 left and right.

[0035] Working principle:

[0036] When the position of the adjusting plate 5 needs to be adjusted, moving the pulling rope 12 can cause the snap-fit ​​plate 92 to move, which in turn moves the snap-fit ​​rod 93, causing the snap-fit ​​rod 93 to disengage from the snap-fit ​​groove 11. Then the moving block 4 can be moved left and right, which in turn moves the position of the adjusting plate 5. The position of the adjusting plate 5 can be adjusted according to the horizontal width of the connecting printed plate 8, which improves the performance of the connecting printed plate 8.
