[0002] Currently, disposable sanitary products are mostly produced on automated production lines; in existing sanitary product production lines, product welding and slitting are mostly completed simultaneously in the same process to avoid phase shifts when they are completed separately, which would result in poor product appearance.

[0003] For example, Chinese patent CN212653887U discloses an ultrasonic processing device for sanitary products, in which an ultrasonic welding vibrator is located below the product, and ultrasonic welding rollers and cutting rollers are arranged front and back along the axis of the rotating body. The ultrasonic welding rollers and cutting rollers reciprocate in the direction of the rotating axis, and in this process, the welding and slitting of the product are completed simultaneously; the cutter structure is arranged behind the welding wheel, and although the front and back are completed synchronously, the cutter is in direct contact with the working surface of the welding head to cut the product, which greatly shortens the service life of the cutter and the welding head, so the cutter and the welding head need to be replaced frequently; at the same time, the product is cut by ultrasonic vibration, and the cut edge of the product is harder than that of conventional cutting methods, which affects the user experience.
