[0002] Packaging film printing is used to produce packaging films with specific patterns. Generally, patterns, text, or other information are printed on various types of packaging films. This technology is widely used in many industries such as food, home building materials, and electronics to improve the attractiveness and recognizability of products, make it easier for consumers to identify and understand the contents, and enhance the aesthetics of packaging through color, patterns, and design, making it stand out on the shelf and stimulating the desire to buy.
[0003] During the printing process, packaging film needs to be printed using a printing press. To prevent wrinkles from forming due to its own weight or external forces during printing, which would affect the printing effect, and to ensure that the packaging film is taut and flat during printing, a support device for printing and conveying packaging film is needed. This device uses a cylinder to drive the driven roller to move up and down, so that the driving roller and the driven roller limit the packaging film, ensuring that the packaging film is taut and flat during printing. This effectively prevents the packaging film from sagging due to its own weight or external forces during printing, thus improving the printing accuracy of the packaging film. Utility Model Content

A fixing block 15 is welded to the top of sliding rod 14.
[0025] Example 2:
[0026] Figure 1-4This invention illustrates a support device for printing and conveying packaging film according to an embodiment of the present invention. It includes: a workbench 1; a printing machine 2 fixedly connected to the top of the workbench 1; packaging film 3 disposed on the surface of the printing machine 2; two symmetrical fixed plates 4 fixedly connected to the top of the workbench 1 by bolts; a drive roller 5 installed between the two fixed plates 4; slide rails 6 fixedly connected to the inner walls of both fixed plates 4; sliders 7 slidably connected to the surface of the slide rails 6; a driven roller 8 rotatably connected between the two sliders 7; a U-shaped plate 9 rotatably connected to the surface of the driven roller 8; a top plate 10 welded to the top of the two fixed plates 4; and a cylinder 11 fixedly connected to the top of the top plate 10. The output end of the cylinder 11 extends through the inner wall of the top plate 10 and is fixedly connected to a connecting plate 12. Two symmetrically arranged slide rods 14 are fixedly connected to the top of the U-shaped plate 9. A fixing block 15 is welded to the top of the slide rod 14. A spring 16 is sleeved on the surface of the slide rod 14. The two ends of the spring 16 contact the connecting plate 12 and the U-shaped plate 9 respectively. The position of the spring 16 can be adjusted according to the thickness change of the packaging film 3 to maintain constant pressure. A ball bearing 17 is installed between the surface of the slide rod 14 and the inner wall of the connecting plate 12. The ball bearing 17 reduces the friction between the connecting plate 12 and the slide rod 14, thereby extending the service life of the connecting plate 12 and the slide rod 14.
[0027] Working principle: When using this utility model, the user pulls the packaging film 3 from the previous process to the surface of the drive roller 5, and then starts the cylinder 11, which drives the connecting plate 12 to move down. At this time, with the cooperation of the slide rod 14 and the fixed block 15, the slide rod 14 drives the U-shaped plate 9 to move down, which in turn drives the driven roller 8 to move down. The cooperation of the slide rail 6 and the slider 7 limits the movement of the driven roller 8 and the U-shaped plate 9, preventing them from shaking during movement. This limits the packaging film 3. Then, the drive roller 5 is started, which drives the packaging film 3 to move, thus conveying the packaging film 3 to the surface of the printing machine 2 for printing. This effectively avoids the packaging film from sagging due to its own weight or external force during printing, which would affect the printing effect, thereby improving the printing accuracy of the packaging film.
[0028] In summary, this support device for printing and conveying packaging film pulls the packaging film 3 from the previous process to the surface of the drive roller 5, causing the cylinder 11 to drive the connecting plate 12 to move downward. With the cooperation of the slide bar 14 and the fixing block 15, the U-shaped plate 9 drives the driven roller 8 to move downward and limit the packaging film 3. At this time, the drive roller 5 is activated, so that the drive roller 5 transports the packaging film 3 to the surface of the printing machine 2 for printing. This effectively avoids the packaging film from sagging due to its own weight or external force during printing, which would affect the printing effect, thereby improving the printing accuracy of the packaging film.
