Tension-adjustable sizing equipment for high-strength carbon fiber production

Abstract

The invention discloses tension-adjustable sizing equipment for high-strength carbon fiber production, relates to the technical field of carbon fiber production, and aims to solve the problems that existing carbon fiber sizing is generally performed through soaking, high tension needs to be kept during soaking sizing of carbon fiber yarns, the tension of the carbon fiber yarns cannot be adjusted by existing equipment, carbon fiber yarns are too loose, sizing is not uniform enough, the sizing quality is poor, and when the carbon fiber yarns are sized, slurry is still in a sizing frame for a long time, so that organic molecules in the slurry are precipitated and layered, and the sizing effect is influenced are solved. Four supporting rods are fixedly arranged on the upper end face of the base, a sizing mechanism is arranged over the four supporting rods, guide mechanisms are arranged at the two sides of the sizing mechanism, and two supporting seats are fixedly arranged on one side of the upper end face of the base.

Description

technical field [0001] The invention relates to the technical field of carbon fiber production, in particular to a sizing device for high-strength carbon fiber production with adjustable tension. Background technique [0002] Carbon fiber refers to a high-strength and high-modulus fiber with a carbon content of more than 90%. Its high temperature resistance ranks first among all chemical fibers. In order to prevent carbon fiber from absorbing dust and moisture in the air and reduce the impact of wear during subsequent processing, it is necessary to sizing the carbon fiber material to form a protective film on the surface of the carbon fiber material to protect the carbon fiber material. [0003] Existing carbon fiber sizing is generally done by soaking and sizing, and carbon fiber filaments must maintain a high degree of tension during soaking and sizing, and the existing equipment cannot adjust the tension of carbon fiber filaments, which will make the carbon fiber filament...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a sizing equipment for high-strength carbon fiber production with adjustable tension, so as to solve the problem that the existing carbon fiber sizing proposed in the above-mentioned background technology is generally sizing by soaking, and the carbon fiber filaments must be maintained during soaking and sizing. Higher tension, and the existing equipment cannot adjust the tension of carbon fiber filaments, which will make the carbon fiber filaments too loose, resulting in uneven sizing, resulting in poor sizing quality, and when the carbon fiber filaments are sizing, the sizing solution is sizing The inside of the frame will be static for a long time, which will cause the organic molecules inside the slurry to precipitate and stratify, thus affecting the sizing effect
