产品名称：凸键加重型气胀轴

凸键加重型气胀轴 Convex key weighted inflation shaft
此型号气胀轴气胀轴是一种专为高负载卷材收放卷设计的精密机械部件，采用高强度合金钢材质与凸键式表面结构，通过内部气压膨胀实现轴体与卷芯的快速锁紧与释放。其核心设计结合凸键咬合技术与加重型壁厚，可适配各类高张力、大重量卷材（如金属箔、厚膜、重型织物等），广泛应用于印刷、包装、锂电、纺织等工业领域。
 

This model of inflatable shaft is a precision mechanical component designed specifically for high load coil winding. It is made of high-strength alloy steel material and has a convex key surface structure. Through internal air pressure expansion, the shaft and core are quickly locked and released. Its core design combines convex key biting technology and heavy-duty wall thickness, which can adapt to various high tension and heavy weight rolls (such as metal foil, thick film, heavy-duty fabrics, etc.), and is widely used in industrial fields such as printing, packaging, lithium batteries, textiles, etc.
