Abstract

The present invention provides a carbon fiber expanding device. The carbon fiber expanding device includes an expanding roller set, and the expanding roller set includes N expanding rollers, wherein, N is an odd number greater than or equal to 3, and the outer surface of the expanding roller is along the axial direction. At least one guide groove is evenly arranged, and the N expanding rollers include upper rollers and lower rollers, and the upper rollers and the lower rollers are arranged alternately above and below the carbon fiber bundles, and wherein the upper rollers are distributed on the same In the horizontal plane, the lower rollers are distributed in the same horizontal plane. According to the carbon fiber expansion device of the present invention, the structure is simple and easy to use. During the expansion process of the carbon fiber bundle passing through the upper roller and the lower roller alternately, it continuously widens and becomes thinner, so that the width and thickness of the carbon fiber bundle after expansion are uniform and moderate; and the carbon fiber bundle of the present invention The carbon fiber expansion device can adjust the lifting of the expansion roller, so that the expansion tension can be adjusted as required to meet the expansion requirements of different carbon fiber bundles.

Description

technical field [0001] The invention relates to the technical field of fiber bundle expansion, in particular to a carbon fiber expansion device. Background technique [0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. Carbon fiber is lighter than metal aluminum, but its strength is higher than that of steel, and it has the characteristics of corrosion resistance and high modulus. It is an important material in national defense and civilian applications. It not only has the inherent intrinsic characteristics of carbon materials, but also has the softness and processability of textile fibers. It is a new generation of reinforcing fibers. [0003] With the development of fiber sheets, the expansion of carbon fibers is also becoming more and more important. However, the existing technology is too simple to expand the carbon fiber, and cannot adjust the expansion tension at any time during the expansio...
