Title:
AIRFLOW DISTURBANCE-TYPE CARBON FIBER WIDENING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2023/116059
Kind Code:
A1
Abstract:
An airflow disturbance-type carbon fiber widening equipment, comprising an unwinding module, an unwinding tension control module, an airflow disturbance widening module, a winding tension stabilizing module, a deviation correction module, and a winding module which are sequentially provided in a feeding direction. A widening mechanism comprises the airflow disturbance widening module; the airflow disturbance widening module comprises two sets of airflow disturbance widening assemblies; each set of airflow disturbance widening assembly comprises a centrifugal fan; the centrifugal fans are communicated with the bottoms of airflow ducts; three sets of widening guide shafts are provided side by side at the top of each airflow duct; a tension adjusting assembly is provided between the two sets of airflow disturbance widening assemblies; the widening guide shafts and the tension adjusting assembly all match a carbon fiber (6); a widening guide shaft VII (13) is located at an upper port of an airflow duct I (25) and is connected to a sliding block module II (34); and when the widening guide shaft VII (13) moves along its own axial direction, a transverse force is applied to the carbon fiber to facilitate the widening of the carbon fiber. According to the carbon fiber widening equipment, airflows are provided by using frequency-adjustable centrifugal fans, so that stable negative pressure is formed at the upper ends of the airflow ducts, and the surrounding air forms a stable airflow under the action of the pressure; in addition, with the assistance of the widening guide shafts, a carbon fiber tow is uniformly dispersed.
