Edge cutting mechanism of film blowing machine

The utility model discloses an edge cutting mechanism of a film blowing machine, and relates to the technical field of film processing equipment.The edge cutting mechanism comprises a processing frame, the processing frame is connected with a cutting mechanism, the processing frame is rotationally connected with at least two winding rollers, the processing frame is connected with a driving assembly used for driving the winding rollers to rotate, and the processing frame is connected with a film separating piece used for separating two layers of films; the film separating piece is located between the winding roller and the cutting mechanism. The cutting mechanism is used for cutting the two sides of the thin film, so that the thin film with the corresponding width is obtained. The two ends of the two layers of films are connected to the two winding rollers correspondingly, the driving assembly drives the two winding rollers to rotate, and therefore the films are wound. The film separating part is located betwe
