Problems solved by technology

Because the carbon fiber yarns are not evenly laid out but randomly arranged into yarns like ellipses, the above-mentioned heating method tends to heat the carbon fiber bundles unevenly. The thick part of the sizing agent has not been completely melted, so the carbon fiber spreading effect is seriously affected

Embodiment Construction

[0018] Attached below figure 1 The present invention is described in further detail, see attached figure 1 .

[0019] attached figure 1 It is a schematic diagram of a carbon fiber spreading device of the present invention: the carbon fiber bundle (8-1) passes through the first guide roller (11-1) and the second guide roller (11-2) on the first support (9-1). ) of the first pair of tangential guide rollers formed into the third guide roller (5-2) in the carbon fiber spreading device, and the carbon fiber bundle bypasses the heating roller (1-1) and its heating ring (2-1 ), through the fourth guide roller (5-1) and the fifth guide roller (5-3), drafted onto the second support (9-2) by the sixth guide roller (5-4) by The second pair of tangent guide rollers formed by the seventh guide roller (11-3) and the eighth guide roller (11-4) are then processed in the subsequent process; wherein the carbon fiber bundle is adjusted by adjusting The distance between the fourth guide roll...

Abstract

The invention relates to a carbon fiber unfolding device for regulating and controlling heating of a carbon fiber bundle by a method of controlling a contact area of the carbon fiber bundle on a heating roll, and unfolding the carbon fiber bundle under the grinding action of yarn guide rolls. According to the carbon fiber unfolding device, the carbon fiber bundle can be heated more uniformly, and can become lighter and thinner by controlling a heating area; a fiber unfolding effect is better; with the adoption of the technical scheme, the carbon fiber bundle can be broadened and thinned obviously; and a carbon fiber is low in strength loss and reliable in quality.

Description

technical field [0001] The invention relates to a carbon fiber spreading device, which belongs to the field of textile processing and textile machinery. technical background [0002] In recent years, with the rapid development of wind power and automobile industries, carbon fiber reinforced resin matrix composites have made great progress. The carbon fiber used as reinforcement mainly includes carbon fiber prepreg and carbon fiber fabric. Whether it is carbon fiber prepreg or carbon fiber fabric, the thinner the fabric, the smaller the mass per unit area, the smaller the deviation of its physical properties, and the better the mechanical properties. Because the lighter and thinner the carbon fiber, the product will be lighter and thinner, and the performance will be better. Therefore, the carbon fiber bundle before sales and the carbon fiber bundle before weaving generally have to go through the fiber spreading process. [0003] At present, the fiber spreading of carbon fi...
