Description

Technical Field

[0001] This utility model relates to the field of BOPP film technology, and in particular to a printing BOPP film conveying and guiding device. Background Technology

[0002] When guiding BOPP film during the printing process, a printing BOPP film conveying and guiding device is often used. This device is specifically designed to guide and control the smooth and precise transfer of BOPP film during printing. By ensuring the linear movement and positioning accuracy of the film, it effectively reduces printing quality problems caused by film misalignment or wrinkles, thereby improving production efficiency and yield. Using this guiding device brings many benefits, including improved printing accuracy, faster production speed, reduced scrap rate, and enhanced operational safety and convenience, thus saving costs for enterprises and enhancing their market competitiveness.

[0003] The BOPP film conveying and guiding device first installs the BOPP film roll to be printed on the unloading shaft and adjusts the film tension through tension control. Next, the film is smoothly fed into the printing area via a conveyor consisting of guide rollers and tension rollers. In the printing area, the film passes through printing rollers to print patterns or text. Then, the printed film continues to pass through guide rollers and tension rollers into the drying area for ink drying. Finally, the dried film is wound onto the take-up shaft, completing the entire printing process.

[0004] Existing technologies for printing BOPP film conveying and guiding devices have several shortcomings when dealing with BOPP film, a material with unique texture and stringent conveying requirements. Common conveying equipment often employs a simple roller guide structure. This structure cannot effectively control the flatness of the film during high-speed conveying, easily leading to wrinkles and misalignment during transport. Such problems severely impact printing quality, causing misregistration and uneven ink distribution, and can also interrupt subsequent processing steps, increasing production costs and time. Furthermore, existing guiding devices lack precise tension control over the BOPP film. Unstable tension during transport can cause film stretching and deformation, affecting its physical properties and printing results. Therefore, this paper proposes a new printing BOPP film conveying and guiding device to address these issues. Utility Model Content

[0045] Working principle: In this printed BOPP film conveying and guiding device, motor 2 drives drive roller 3 to rotate, which in turn drives unwinding roller 4 to unwind the printed BOPP film to be conveyed. The film passes through the conveying channel formed by drive roller 7 and driven roller 8 driven by motor 6 in frame 5. In this process, the initial conveying and guiding are achieved. Subsequently, the film enters frame 9, where drive roller 11 and driven roller 12 driven by motor 3 drive the film to further convey and guide it. Finally, motor 4 drives drive roller 14 to rotate, which drives take-up roller 15 to neatly wind and rewind the conveyed printed BOPP film.

[0046] Motor 16 starts, providing power for the rotation of drive shaft 17. The rotation of drive shaft 17 drives the rotating wheel 18 to rotate. The rotating wheel 18 transmits the rotational power through belt 19, realizing the initial adjustment of membrane tension. Motor 2 drives drive roller 3 to rotate. At the same time, follower block 21 slides in the slide groove 20 on the front side of the cabinet 1. By contacting or connecting with the membrane, it changes its position to change the membrane tension, realizing further adjustment of membrane tension. In addition, two pneumatic sliders 23 slide on the linear slide rails 22 on the left and right sides of the outer wall of the cabinet 1. Through the connecting plate 24, they drive tension roller 25 to move. Tension roller 25 contacts the membrane, further adjusting the membrane tension and ensuring the stability of membrane tension during the conveying process.

[0047] 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.
