A carbon fiber prepreg tow swing rod type segmented small tension conveying method and device

Abstract

A carbon fiber prepreg tow pendulum-type segmental low-tension conveying method and device. When laying, the prepreg tow is sent out by the conveying module after passing through the unwinding module, and enters the constant tension swing-rod type buffer module, and the prepreg tow The tension is divided into two independent parts by the conveying module. The tension value of the carbon fiber prepreg tow before the conveying module is controlled by the unwinding module, and the tension value of the carbon fiber prepreg tow after the conveying module is controlled by the constant tension swing rod type buffer module. control, so as to realize the control of different tensions in different parts of the prepreg tow. The present invention can maintain different tensions for the prepreg tows at different positions during the conveying process, that is, the tension at the laying roller is small and the tension at the discharge position is relatively large, and at the same time, it can ensure that the prepreg tows can also be Maintain stable small tension, no large fluctuations, and simple structure.
