The utility model discloses online stripping equipment for a transfer film. The online stripping equipment is characterized in that: at a position where semi-finished transfer aluminum paper is put into a slitting procedure, a host machine is provided with a rotatable film stripping air expansion shaft; the film stripping air expansion shaft is supported on air expansion shaft brackets on both sides of the host machine; the transfer film in the semi-finished transfer aluminum paper is rolled on the rotatable film stripping air expansion shaft; and mold-stripped transfer aluminum paper enters a subsequent slitting procedure. According to the online stripping equipment, online stripping of a slitting machine transfer film is completed, and stripping and slitting procedures are continuously completed during production of single end transfer aluminum paper, so that procedures are reduced, production cost is lowered, and production efficiency is improved.
