A high grammage carbon fiber yarn spreading device

Abstract

The present invention relates to the technical field of carbon fiber processing equipment, in particular to a high-grammage carbon fiber yarn spreading device, which includes a plurality of second adjustment rollers and a plurality of fiber spreading rollers arranged in a staggered manner, and a first adjustment roller arranged in a vertical direction and the third regulating roller, and a tension sensor is also arranged on the third regulating roller. Through the multi-layer vibration spreading of fiber spreading rollers, the uniform spreading of large tow carbon fiber yarns can be realized, and the tension value of the fiber tow can be adjusted layer by layer with multiple second adjustment rollers arranged at intervals, so that it enters the weaving process. The tension value is the same; the first regulating roller, the second regulating roller, the fiber spreading roller and the third regulating roller are arranged in multiple groups along the horizontal direction, so that the fiber spreading or tension value adjustment of the multi-layer fiber tow in different horizontal planes can be adjusted. It is carried out as a whole, wherein the first adjustment roller can be adjusted independently, and the tension value of each layer of yarn is adjusted individually according to the detection value of the tension sensor, so as to ensure that the tension value of the multi-layer fiber tow is adjusted consistently and the thickness is uniform.

Description

technical field [0001] The invention relates to the technical field of carbon fiber processing equipment, in particular to a high-gram-weight carbon fiber yarn spreading device. Background technique [0002] With the development of lightweight wind turbine blades and automobiles, the requirements for carbon fiber cloth are: cost reduction and high grammage. The first consideration is to meet the requirements of cost reduction. The production of carbon fiber unidirectional fabrics is woven with wide-width high-speed warp knitting equipment, and the raw materials are made of large tow carbon fibers to meet the requirements of low cost. [0003] During the weaving process, it is necessary to spread the large tow carbon fiber yarn to ensure that the thickness and tension of each layer of carbon fiber tow entering the weaving process are uniform and consistent, so that the woven carbon fiber unidirectional fabric can meet the performance of the use However, the accumulation of l...

Problems solved by technology

[0003] During the weaving process, it is necessary to spread the large tow carbon fiber yarn to ensure that the thickness and tension of each layer of carbon fiber tow entering the weaving process are uniform and consistent, so that the woven carbon fiber unidirectional fabric can meet the performance of the use However, the accumulation of large tow carbon fiber yarns is high and the yarn phenomenon is serious, which is not conducive to the uniform fiber spreading of carbon fiber yarns. The traditional vibration fiber spreading device cannot meet the uniform fiber spreading of large tow carbon fiber yarns. After fibering, the tension value of each layer of fiber tow will be changed to varying degrees
