Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of carbon fiber manufacturing, in particular to a carbon fiber sizing and width expanding device. Background Art
[0002] The factor that determines the width of carbon fiber products mainly lies in the carbonization process of carbon fiber production and preparation. In the carbonization process, the carbon fiber needs to go through a sizing process to improve the surface properties of the carbon fiber, and then be dried and wound into a roll to obtain the finished carbon fiber. The solute of the sizing solution used in the sizing process is mainly epoxy resin. After being immersed in the sizing solution, the carbon fiber spontaneously bundles to form rod-shaped fibers, and then tends to form a narrow width carbon fiber product after drying and finalization. After searching, a carbon fiber sizing and width expansion device is disclosed in the Chinese patent with the authorization announcement number CN218711443U, including a first roller, a first pressing roller, and a second roller. The first roller, the first pressing roller and the second roller are arranged in parallel and spaced from front to back along the traveling direction of the carbon fiber tow. When the first pressing roller does not squeeze and apply force to the carbon fiber tow, the carbon fiber tow is tensioned between the first roller and the second roller along the first path, and the carbon fiber tow forms a wrap angle on the first roller and the second roller. The first pressing roller can squeeze and apply force to the carbon fiber tow along the first direction so that the carbon fiber tow deviates from the first path and travels along the second path. According to the utility model, the first roller, the second roller and the first pressing roller are arranged in parallel and at intervals along the traveling direction of the carbon fiber tow. When the first pressing roller extrude the carbon fiber tow, the carbon fiber tow deviates from the first path. At the same time, at least one of the first roller and the second roller cooperates with the first pressing roller to form an effect of staggered extrusion of the carbon fiber tow, thereby improving the width expansion effect of the carbon fiber tow.
[0003] However, in actual use of this solution, since the sixth roller is fixed to the sizing tank structure, the carbon fiber is in contact with the slurry for a short time and can only stay there for a short time. Some carbon fibers cannot adhere to the slurry, which causes slurry fracture in the subsequent width expansion treatment. Secondly, the static sizing tank is prone to slurry sedimentation and stratification, which is not conducive to uniform sizing of the carbon fiber.
[0004] Therefore, we made improvements on this and proposed a carbon fiber sizing width expansion device. Utility Model Content
