Special production tooling for high-strength carbon fiber

Abstract

The invention provides a special production tooling for a high-strength carbon fiber. The special production tooling comprises sizing equipment, an opening and shaping device, a drying device and a carbon fiber bundle, wherein the sizing equipment comprises a sizing shell, a pre-spraying pump, a spraying pipe, a spraying pipe bracket, spray headers, an air inlet pipe, an air curtain machine, a waste liquid draining pipe, a first sizing roller, a second sizing roller, a third sizing roller, a first dipping roller, a second dipping roller, a fourth sizing roller, a fifth sizing roller and a positioning roller; the opening and shaping device comprises a workbench, a boss, guide roller brackets, guide rollers, a frame, paired roller brackets, upper paired rollers, hydraulic rods and lower paired rollers; the drying device comprises a drying shell, a partition plate, preheating section rollers, drying section rollers, heating pipes, a return air draught fan, a main air pipe, a preheating air pipe, a circulating air pipe, a fresh air pipe, a circulating draught fan and air valves. The special production tooling for the high-strength carbon fiber has the advantages that the carbon fiber bundle can be standardized, specialized and integrated, high-standard production requirements can be met, and the phenomenon that the carbon fiber bundle is disordered and broken is avoided systematically, and the system stability is strong.

Description

technical field [0001] The invention belongs to the field of carbon fiber production equipment, in particular to a special production tool for high-strength carbon fiber. Background technique [0002] Carbon fiber is a new type of fiber material with high strength and high modulus fiber containing more than 95% carbon. It is a microcrystalline graphite material obtained by stacking organic fibers such as flake graphite microcrystals along the axial direction of the fiber, and undergoing carbonization and graphitization. Carbon fiber is "soft on the outside and rigid on the inside", lighter than metal aluminum, but stronger than steel, and 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. Carbon fiber ...

AI Technical Summary

Problems solved by technology

[0004] In the existing patent technology, a patent with the patent number "CN201520098738.6" and the patent name "a preparation equipment for ultra-thin carbon fiber bundles" is disclosed. The following technical defects exist in the prior art: (1) the preparation equipment The structure is too simple. When the carbon fiber bundles go through sizing, fiber opening and shaping, and drying in sequence, the carbon fiber processing is simple. There is no special equipment for professional and integrated processing of the carbon fiber bundles, and the carbon fiber bundles are not processed sufficiently. Satisfied with the effect

(2) The carbon fiber bundles are not protected in the equipment, because the carbon fiber bundles are in a long-term and long-distance conveying state, and the system is used to adjust the tension and position of the carbon fiber bundles, and the carbon fiber bundles have broken and disordered filaments
