[0001] The utility model relates to the field of carbon fiber production, in particular to an active unwinding device capable of manually adjusting centering. Background Art
[0002] As we all know, in recent years, the market demand for carbon fiber composite materials is growing rapidly due to its unique high strength, low density, corrosion resistance, and anti-aging properties. The material unwinding device is the most common mechanical structure in carbon fiber composite equipment. Relying on this structure, roll products such as release paper, resin film, PE film, and fabric are released. With the upgrading of equipment and customers' strict requirements on process data (tension changes, speed changes) in the product production process, the process data of the traditional passive unwinding method can no longer meet the performance requirements, resulting in uneven unwinding tension and speed, which is easy to cause low production efficiency and unstable product quality.

[0010] like Figure 1 and Figure 2 A base 11 is provided, a roll diameter sensor mounting plate 10 is placed next to the base 11, a roll diameter sensor 9 is installed on the roll diameter sensor mounting plate 10, two left and right frames 7 are fixedly installed on the base 11, a mounting plate 6 and an adjustment slide 5 are installed on the top of the frame 7, the adjustment slide 5 on the right is driven by a screw, a hand wheel is installed at the end of the screw, a servo motor frame 12 is installed on the left frame 7, a servo motor 1 is installed on the servo motor frame 12, and the right end of the servo motor 1 is connected and installed with a sliding shaft coupling 3, a safety chuck 4, and an air shaft 8 in sequence, and the air shaft The right side of 8 is connected and installed with another safety chuck, a shield 2 is installed on the outside of the sliding shaft coupling 3, and two safety chucks 4 are respectively fixedly installed on the adjustment slides 5 of the left and right frames 7. One end of the sliding shaft coupling 3 cooperates with the shaft hole of the servo motor 1, and is radially positioned using a key, and is axially fixed using a fastening bolt. The other end of the sliding shaft coupling 3 also cooperates with the shaft hole clearance of the safety chuck 4, and is radially positioned using a key. The safety chuck 4 is installed on the upper surface of the adjusting slide 5 and is fixed with bolts, and the adjusting slide 5 is installed on the mounting plate 6 and fixed with bolts.

The device also has the function of manual adjustment and centering. If the product deviates from the center line during the release process, the hand wheel of the adjustment slide 5 is manually shaken, and the slide will drive the upper safety chuck 4 and the pneumatic shaft 8 to move forward and backward together. At this time, the shaft of the safety chuck 4 will move forward and backward in the assembly hole of the sliding shaft coupling 3, so that the material can be readjusted and centered without stopping the production process.
