Winding battery diaphragm cutting device

The utility model discloses a coiled battery diaphragm cutting device, relates to the technical field of coiled battery processing equipment, and provides the following scheme aiming at the problems that when the existing coiled battery diaphragm cutting device is used for cutting a diaphragm, the diaphragm is easily adhered to a blade, so that the cut part of the diaphragm is wrinkled, and the quality of the diaphragm is influenced. The diaphragm cutting device comprises a conveying mechanism and a cutting mechanism, the conveying mechanism is used for supporting the cutting mechanism and conveying a diaphragm, the conveying mechanism is installed below the cutting mechanism, the cutting mechanism is used for cutting the diaphragm, and a pressing plate used for limiting the position of the diaphragm is arranged in the cutting mechanism. According to the diaphragm cutting device, the diaphragm needing to be cut is conveyed into the cutting mechanism through the conveying mechanism, and after the diaphragm is
