湿法缠绕在线自动配胶系统研究

RESEARCH ON A RESIN MIXING AND IMPREGNATING SYSTEM FOR FILAMENT WINDING ON LINE

针对现有湿法缠绕中间歇配胶-浸渍的适用期限制、固化剂含量与含胶量波动等问题,提出了缠绕自动化配胶的一种解决方案:以PLC控制两台蠕动泵输送树脂和固化剂至动态混合器的流速的方式来实现精确配比,以编码器采集的纤维出纱速度输入PLC控制总出胶量的方式来保证缠绕件含胶量;搭建在线自动化配胶试验系统。初步验证结果显示:系统可以实现在线自动连续配胶且没有适用期限制,不同缠绕速度下树脂与固化剂的理论值与实验值误差在±2%以内。

Due to the limitation of the shelf-life, the curing agent content and the fluctuation of the resin content in the present wet-wound winding, we propose a winding resin automatic mixing and impregnating solution. The PLC controls the flow speed of the two peristaltic pumps to transport the resin and curing agent to the dynamic mixer to achieve an accurate ratio, the fiber output speed sampled by the encoder is input to the PLC to control the total amount of resin to ensure the resin content in tows, and a resin automatic mixing and impregnating system on line is built. The preliminary testing results demonstrate that the system can achieve online continuous automatic impregnation of resin with no applicable period limitation. The error between theoretical and experimental values of resin and curing agent at different winding speeds is within ±2%.
