[0002] Vibrant printing is a printing process that uses special techniques and multiple colors to create vivid, three-dimensional, and visually impactful effects. It often uses high-quality inks, including metallic, fluorescent, and transparent inks, enabling rich color gradations and delicate details. It is widely used in advertising materials, product packaging, art printing, and modern home furnishings. To ensure color consistency and print quality, and to avoid defects such as color differences, omissions, and ghosting, a printing apparatus with uniform printing properties is required.

[0003] In existing printing equipment, paper is typically guided to the printing roller via a guide roller. During this process, the lack of paper correction causes the paper to move due to printing pressure, resulting in uneven printing. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a printing device that produces uniform printing, aiming to improve the problem of the lack of paper correction during the use of printing devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0024] Reference Figure 1-Figure 3 This utility model provides an embodiment of a printing device for uniform printing, comprising a worktable 1, a support rod 6 fixedly connected to the upper surface of the worktable 1, a work box 7 fixedly connected to the upper surface of the support rod 6, a hydraulic cylinder 8 fixedly connected to the upper surface of the work box 7, a push block 9 fixedly connected to the output end of the hydraulic cylinder 8, a rack 10 fixedly connected to the lower surface of the push block 9, a gear 12 meshing with the outer wall of the rack 10, a rotating shaft 13 rotatably connected inside the gear 12, and the upper surface of the rotating shaft 13 fixedly connected to the inner wall of the work box 7. A clamping plate 11 is fixedly connected to the lower surface of the worktable 1. A sliding rod 14 is slidably connected inside the clamping plate 11. Both ends of the sliding rod 14 are fixedly connected to the inner wall of the work box 7. A guide seat 2 is fixedly connected to the upper surface of the worktable 1. A printing roller 3 is provided on the upper inner wall of the guide seat 2. A pressure roller 4 is provided on the lower inner wall of the guide seat 2. A drying assembly is provided on the inner wall of the guide seat 2. The drying assembly is used to dry the printed paper. The drying assembly includes a drying roller 5. Both ends of the drying roller 5 are provided on the inner wall of the guide seat 2. The outer wall of the drying roller 5 is provided on the upper surface of the worktable 1.

[0025] Specifically, by activating the hydraulic cylinder 8 to push the push block 9, the rack 10 moves forward, causing the gear 12 to rotate to the left on the outer wall of the rotating shaft 13, which in turn drives the clamping plate 11 to move forward and backward, thus adapting to different sizes and types of paper. The rotation of the gear 12 by the rotating shaft 13 provides support, the sliding of the clamping plate 11 by the slide rod 14 limits the offset, the inner wall of the working box 7 limits the range of the clamping plate 11, and the support rod 6 fixes the working box 7. The rollers on the right inner wall of the guide seat 2 guide the paper to the printing roller 3 and the pressure roller 4. Under the action of the printing roller 3 and the pressure roller 4, the paper is printed, and the drying roller 5 dries the printed paper.

[0026] Reference Figure 2 and Figure 3 The outer wall of the push block 9 is slidably connected to the inner wall of the work box 7, the left outer wall of the rack 10 is slidably connected to the inner wall of the work box 7, the lower surface of the clamping plate 11 is set on the upper surface of the worktable 1, and the outer wall of the clamping plate 11 is slidably connected to the inner wall of the work box 7.

[0027] Specifically, the sliding of the push block 9 by the inner wall of the working box 7 achieves the effect of offset limitation, and the back-and-forth movement of the rack 10 by the inner wall of the working box 7 achieves the effect of guidance.

[0028] Reference Figure 4 A telescopic rod 15 is fixedly connected to the lower surface of the workbench 1, a base plate 16 is fixedly connected to the lower surface of the telescopic rod 15, and a motor 17 is fixedly connected to the upper surface of the base plate 16. A worm gear 18 is fixedly connected to the output end of the motor 17, and a worm wheel 19 is meshed with the outer wall of the worm gear 18. A connecting rod 20 is fixedly connected inside the worm wheel 19, and a gear 22 is fixedly connected to the rear outer wall of the connecting rod 20. A fixing plate 21 is rotatably connected to the middle outer wall of the connecting rod 20, and the lower surface of the fixing plate 21 is fixedly connected to the upper surface of the base plate 16. A gear 23 is meshed with the outer wall of the gear 22. The upper surface of the gear 23 is fixedly connected to the lower surface of the workbench 1, and a hollow column 24 is slidably connected to the outer wall of the gear 23. The lower surface of the hollow column 24 is fixedly connected to the upper surface of the base plate 16.

[0029] Specifically, the telescopic rod 15 connects the worktable 1 and the base plate 16, and also restricts the movement of the worktable 1. The fixed plate 21 on the upper surface of the base plate 16 supports the rotation of the connecting rod 20. The hollow column 24 restricts the movement of the gear 23. The up-and-down movement of the gear 23 drives the worktable 1 to move up and down. When the device is not in use, the worm gear 18 and worm wheel 19 lock the worktable 1 in place.

[0030] Working principle: When using this device, rollers are installed on the inner right side of the guide seat 2. The paper moves along the outer wall of the rollers on the guide seat 2 into the gap between the printing roller 3 and the pressure roller 4. The printing roller 3 prints on the paper, and the pressure roller 4 provides additional pressure to the paper, thus achieving a clear printing effect. Finally, the printed paper is dried by passing through the outer wall of the drying roller 5 and guided to other equipment. The hydraulic cylinder 8 pulls the push block 9, which drives the rack 10 to move backward on the inner wall of the working box 7. This causes the clamping plate 11 to slide backward under the restriction of the slide rod 14. The rack 10 drives the gear 12 to rotate to the right under the action of the rotating shaft 13, thereby moving the clamping plate 11 towards the center and correcting the paper to be printed. This device is designed to correct paper deviation and adapt to different types of paper. When not in use, the motor 17 drives the worm gear 18, which in turn drives the worm wheel 19 to rotate to the right. This causes the connecting rod 20 to rotate to the right inside the fixed plate 21. The connecting rod 20 then drives the gear 22 to rotate to the right, which in turn causes the rack 23 to move upward under the constraint of the hollow column 24. This causes the worktable 1 to rise under the action of the telescopic rod 15 and the base plate 16, facilitating cleaning of the device. During use, this device not only corrects the deviation of the printed paper to prevent uneven paper movement, but also adapts to the characteristics of different papers, thus maintaining a uniform printing effect. It also allows for adjustment of the height of the worktable 1 for cleaning as needed, improving the comfort of the staff during cleaning.

[0031] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
