The invention discloses automatic stacking and packaging equipment for sanitary towel production. The automatic stacking and packaging equipment comprises a rack and a stacking mechanism arranged on the rack, the rack comprises a top plate and a bottom plate, the top plate and the bottom plate are fixedly connected through a supporting plate, and a through groove matched with the stacking mechanism is formed in the top plate. The invention relates to the technical field of packaging equipment. According to the automatic stacking and packaging equipment for sanitary napkin production, by arranging a feeding assembly, sanitary towels can be tidily pushed into an interlayer frame for storage in a one-row and one-conveying manner, meanwhile, by means of cooperation of a double-layer gear, a sliding toothed plate and a rotating toothed plate, the feeding assembly can indirectly and regularly push a step supporting seat to move, when the step supporting seat moves by a certain distance, the stacking mechanism can automatically fall down by one layer, then stacking of a second layer can be conducted, neat stacking of the sanitary towels is achieved through the linkage structure, the complexity of manual stacking is omitted, the labor cost is effectively reduced, the working efficiency is improved, and control is easier.
