Electric servo drive uncoiling core shaft taking mechanism for metal precision ultra-thin strip

The invention belongs to the technical field of metal ultra-thin strip production, and particularly relates to an electric servo drive uncoiling and mandrel taking mechanism for metal precise ultra-thin strips, which comprises a main shaft, a push rod is slidably arranged in the main shaft, and a coil supporting device is jointly mounted at the front parts of the push rod and the main shaft; the tail end of the push rod penetrates through the connecting flange, the turntable bearing and the electric cylinder fixing seat to be arranged in the electric cylinder connecting seat, the tail end of the push rod is spherical and is connected with the push-pull block, an oval sliding groove corresponding to the push-pull block in shape is formed in the electric cylinder connecting seat, and the push-pull block is connected with the output end of the servo electric cylinder. The spherical groove is formed in the push-pull block, so that the push rod is rotationally connected with the servo electric cylinder, meanwhile,
