The invention provides a uniformizing device for a large-tow drying densification process. The device comprises at least two drying hot rollers (9), a guide wheel (7) and a supporting structure (10),wherein sheet-like tows (8) are wound on the surfaces of the drying hot rollers (9), and the drying hot rollers (9) are used for drying the sheet-like tows (8); the guide wheel (7) is arranged betweenthe drying hot rollers (9), the outer circumference of the guide wheel (7) is in tensioned contact with the sheet-like tows (8), the tow tension regulation range is 180-550 cN / K, and the tow layer thickness of the sheet-like tows (8) is uniform; the guide wheel (7) is installed on the supporting structure (10). The guide wheel is used for uniformizing the thickness of the sheet-like tows, the structure is simple, and operation is convenient. A concave guide wheel or a convex guide wheel can be conveniently, flexibly and accurately selected according to the nonuniform degree of the tow layer thickness, the practicability is good, and the popularization value is high.
Description
technical field [0001] The invention belongs to the technical field of fiber production, and in particular relates to a leveling device for the drying and densification process of large tow. Background technique [0002] Carbon fiber has the characteristics of high specific strength, high specific modulus, heat resistance, corrosion resistance, fatigue resistance, and creep resistance. It is a high-performance fiber material and has been widely used in aerospace, national defense construction, sports and leisure products, and medical equipment. and construction industry. Carbon fibers can be divided into polyacrylonitrile-based, pitch-based, and viscose-based carbon fibers. Among them, polyacrylonitrile-based carbon fibers are the most widely used, the largest amount used, and the fastest growing, occupying an absolute advantage in carbon fiber production. [0003] Polyacrylonitrile-based carbon fiber is made from polyacrylonitrile fiber through pre-oxidation and carbonizat...
