The invention mainly discloses a film stripping mechanism which comprises a support, an aluminum pressing roller and a rotary shaft, wherein the aluminum pressing roller and the rotary shaft are assembled on the support in parallel in the axial direction. One end of the aluminum pressing roller is in transmission connection with a power source. The film stripping mechanism further comprises a wheel body and a film pressing wheel in rolling connection with the support. A bracket of the film pressing wheel is sleeved with the rotary shaft, and axial limiting of the bracket of the film pressing wheel and the rotary shaft is achieved through an elastic part. A limiting device limiting free axial rotation of the rotary shaft is arranged on one side of the rotary shaft. When the limiting device drives the rotary shaft to rotate axially to a preset station, the wheel body of the film pressing wheel and the aluminum pressing roller are attached to each other in a pressing mode. According to the film stripping mechanism, one end of a film body which is cut into a long strip by a cutter mechanism is placed between the film pressing wheel and the aluminum pressing roller to be tightly pressed, the film body is lifted from the ground through the meshing rotation of the film pressing wheel and the aluminum pressing roller, and the purposes of stripping the film body and continuously conveying the film body to a conveying mechanism on the other side are achieved.
