Special-shaped roller for eliminating layering of membrane electrode frame of fuel cell during coil material conveying

The utility model provides a special-shaped roller for eliminating layering of a membrane electrode frame of a fuel cell during coil stock conveying. The special-shaped roller comprises a core roller main body and a lug boss, wherein the core roller main body is a cylinder. The protruding parts are arranged on the outer wall of the core roller body in the axis direction of the core roller body and used for eliminating staggered layers generated on the frame coil stock. Due to the fact that the protruding parts are arranged on the surface of the cylindrical core roller body and arranged in the axis direction of the core roller body, in the rotating process of the special-shaped roller, the protruding parts can automatically eliminate accumulated staggered layers along with rotation of the core roller body. By means of the special-shaped rollers, the layer staggering phenomenon of the composite frame coil stock can be eliminated in time. 本实用新型提供的一种用于消除燃料电池膜电极边框卷料走带时分层的异形辊，包括芯辊主体和凸起部。其中，芯辊主体为圆柱体。凸起部沿芯辊主体的轴线方向设置于
