Processing equipment for aluminum plastic film of soft package battery

The invention relates to processing equipment for an aluminum-plastic film of a soft package battery, which is used for compounding a protective film on an aluminum foil and is provided with at least one film laminating roller group, the film laminating roller set is composed of a lower roller and two upper rollers, the axes of the two upper rollers are arranged in a splayed shape, and the axes of the two upper rollers and the axis of the lower roller are arranged in a space crossing mode; the roller surface of the lower roller is a cylindrical surface, the roller surface of the upper roller is a concave surface, and after the roller surface of the upper roller is in contact with the roller surface of the lower roller, the contact line is a continuous straight line. In the compounding process, the protective film is in a tightened state in the direction perpendicular to the center line, and the situation that the protective film is wrinkled in the rolling direction, and consequently the longitudinal overlying
