Double-wrinkling device for toilet paper production

The invention relates to the technical field of paper manufacturing, in particular to a double-wrinkling device for toilet paper production, which comprises a raw paper feeding mechanism, a wrinkling mechanism, a guide roller, a pressing roller and a winding roller, the wrinkling mechanism comprises a support frame, an upper-layer drying cylinder, a lower-layer drying cylinder, a scraper component and a driving component, the driving component drives the upper-layer drying cylinder to rotate clockwise, and the upper-layer drying cylinder rotates clockwise. The driving assembly drives the lower-layer drying cylinder to rotate in the anticlockwise direction, the scraper assembly is located between the upper-layer drying cylinder and the lower-layer drying cylinder and comprises a rotating shaft and four sets of blades, the four sets of blades are arranged on the side wall of the rotating shaft at equal intervals, and during working, only the blades on the upper side and the lower side conduct wrinkling operatio
