Embodiment Construction
[0020] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.
[0021] combine figure 1 , a low-cost, high-performance large-tow carbon fiber expansion device provided by the present invention adopts a combination of ultrasonic fiber expansion and acoustic wave expansion to expand large-tow carbon fibers. The device includes a creel 1, the yarn bobbin is placed on the creel 1, the fiber bundle is drawn out from the bobbin, and then enters the pre-spreading device 20, that is, the ultrasonic fiber expansion device, so that the fiber bundle is pre-expanded, and then passes through the detection device 50, Adjust the speed of the fiber bundle, and then feed it into the main spreading device 30, that is, the sonic fiber expanding device, so that the large tow carbon fiber is fully expanded, and finally the stretched large tow fiber is taken up by the pulling and crimping device 40.

The invention provides a low-cost high-performance large-tow carbon fiber spreading device. The low-cost high-performance large-tow carbon fiber spreading device comprises a yarn placing device used for placing of fiber bundles and achieving tension control and is characterized in that after the fiber bundles are led out from the yarn placing device, the fiber bundles enter a pre-yarn-spreading device, the fiber bundles are pre-spread by the pre-yarn-spreading device through an ultrasonic fiber expanding method, the pre-spread fiber bundles pass through the position between a rubber roller and a metal roller, liquid on the surfaces of the fiber bundles is removed under the common squeezing action of the rubber roller and the metal roller, afterwards, the fiber bundles enter a detection mechanism, through the detection mechanism, the speed of the fiber bundles is adjusted, the constant tension of the fiber bundles is guaranteed, the pre-spread fiber bundles with the tension and the speed well adjusted enter a main yarn spreading device, the fiber bundles are spread by the main yarn spreading device through the ultrasonic fiber expanding method, and the spread fiber bundles are rolled up through a traction crimping device. By means of the low-cost high-performance large-tow carbon fiber spreading device, the large-tow carbon fibers can be fully and effectively spread.
Description
technical field [0001] The invention relates to a low-cost and high-bundle carbon fiber spreading device. Background technique [0002] Because the price of large tow carbon fiber, such as 48K, 60K, 360K, 480K, etc., is much cheaper than that of small tow, the price of large tow is only 50%-60% of that of small tow, making the cost of advanced composite materials can be greatly reduced. Both large-tow carbon fiber and small-tow carbon fiber can be made into composite materials, but the material and processing costs are very different. Because from petroleum raw materials to carbon fiber, the value-added relationship is 1 to 3, while making carbon fiber into composite materials, the value-added relationship is 10. That is to say, the cost of carbon fiber in composite materials only accounts for 25%-30%, and the cost of forming and processing subsequent fiber product parts accounts for 70%-75%. The choice of low-cost large-tow carbon fiber can save a large part of the cost ...
