Problems solved by technology

In the traditional carbon fiber production process, the carbon fiber is usually dried in a blast oven directly after the carbon fiber is sized. During this process, the water and liquid resin on the surface of the carbon fiber are easy to evaporate and shrink, resulting in the shrinkage of the filament width during the drying process of the carbon fiber. , this phenomenon seriously hinders the development of ultra-light or ultra-thin carbon fiber products

Abstract

The invention discloses a splitting shaping device and a splitting shaping method of an ultrathin carbon fiber bundle. The splitting shaping device comprises a plurality of groups of filament spreading double-rollers, a heat roller and a levelness adjusting roller, which are sequentially arranged; each group of filament spreading double-rollers is provided with a hydraulic lifting machine, each hydraulic lifting machine is fixed on a support, two ends of the heat roller are fixedly connected to the support, and two ends of a rotating shaft of the levelness adjusting roller are also fixedly connected to the support; when the carbon fiber bundle is transported, the heat roller is fixed and does not rotate. The splitting and shaping method comprises the steps of enabling the carbon fiber bundle with serous fluid on the surface to sequentially pass through the filament spreading double-rollers, uniformly spreading the carbon fiber bundle under the extruding effect of the filament spreading double-rollers and the lubricating effect of the serous fluid, and pressing and flattening the fluctuated fibers in the carbon fiber bundle; enabling the carbon fiber bundle to pass through the heat roller, enabling the heat roller to be fixed and not to rotate, drying the carbon fiber bundle by virtue of the heat roller, and enabling the carbon fiber bundle to maintain the filament width after he carbon fiber bundle is spread. After the splitting shaping device and the splitting shaping method is applied to the carbon fiber production process, the ultrathin and online continuous and rapid production of the carbon fiber bundle can be realized, and the development of a downstream ultralight ultrathin product can be satisfied.

Description

technical field [0001] The invention relates to the technical field of carbon fiber production, in particular to a fiber opening and shaping device and method for ultra-thin carbon fiber bundles. Background technique [0002] At present, the downstream application of carbon fiber is gradually popularized. At the same time, with the development of science and technology, carbon fiber products tend to develop in the direction of ultra-light, ultra-thin, and super-strong. [0003] The surface sizing and drying process of carbon fiber is a necessary process for carbon fiber production. After sizing, the water and resin on the surface of carbon fiber are liquid, and the liquid tends to shrink into small balls under the influence of surface tension. In the traditional carbon fiber production process, the carbon fiber is usually dried in a blast oven directly after the carbon fiber is sized. During this process, the water and liquid resin on the surface of the carbon fiber are easy...
