The invention relates to the technical field of foil processing, in particular to a foil positioning, cutting and forming device. The object of the present invention is to provide a foil positioning and cutting operation that performs cutting and truncating during the conveying process of the foil, and can realize continuous positioning and truncating operations on rolled foils, and has the functions of foil cutting and flattening Forming device. The technical solution is: a foil positioning, cutting and forming device, including a base plate, a bracket, a rotating shaft, a fixed cam, a gear, a mounting frame and a driving motor, etc.; one side of the base plate is fixed with two symmetrically arranged brackets, two Two rotating shafts are installed on the support through bearings. In the present invention, two rollers are used to lift the coiled foil on the bottom plate and limit it, which can prevent one end of the foil from rolling freely during transmission and cutting, and the fixed cam cooperates with the toggle lever The job enables rapid cutting and truncation of the foil while it is being conveyed.
