The utility model discloses online stripping equipment for a transfer membrane. The online stripping equipment comprises a stripping air bulking shaft, air bulking shaft brackets and a rotating device, wherein the air bulking shaft brackets are fixedly arranged on the two sides of a host machine; the stripping air bulking shaft is arranged on the air bulking shaft brackets and is positioned between the two air bulking shaft brackets; the rotating device is fixedly arranged on one side of the host machine; and the stripping air bulking shaft is connected with the rotating device and can rotate around the self axial line under the driving of the rotating device. The stripping air bulking shaft is driven by the rotating device arranged on the host machine to rotate, and with the running of the host machine, the stripping air bulking shaft rotates at the same linear speed. The transfer membrane on a transfer aluminum paper semi-finished product is coiled by the stripping air bulking shaft and then is stripped, so that the transfer membrane is stripped on line. The online stripping equipment is simple in structure, reasonable in design, high in processing efficiency, and stable, safe and reliable in work. The transfer membrane is stripped on line, so that procedures are reduced, the production period is shortened, the production cost is greatly reduced, and the production efficiency is improved.
