The gear rotates, driving the rack rod to move downward along the inclined surface of the fixed platform, so that the push plate pushes the corresponding number of sanitary napkins. The rotating plate rotates after receiving the thrust. As the push plate continues to rotate downward, the rotating plate rotates ninety degrees, so that the corresponding number of sanitary napkins are pushed onto the conveying platform, and other sanitary napkins are blocked by the baffle in the placement box and will not fall until the push plate and the rotating plate are reset. By setting up a material dividing device, the corresponding number of multiple groups of sanitary napkins contained in each package of sanitary napkins can be separated for the final overall packaging, avoiding manual sorting that increases manpower and time costs and possible missing or over-packing, thereby effectively improving the convenience of the equipment.

[0015] In the utility model, a limit device is provided and the second rotating valve is rotated to rotate the bidirectional threaded rod, thereby causing the movable block to drive the limit plates to move toward or away from each other, so that the soft pad contacts the sanitary napkin to limit it, thereby adapting to sanitary napkins of different sizes. When the second spring in the limit plate is in a relaxed state, the second T-block is against the lower surface of the movable table in the highest state. Therefore, when the movable table in the material distribution device is adjusted downward, the second T-block will also be subjected to the pressure of the movable table and then compress the second spring, so that the T-block slides downward in the T-slot, thereby cooperating with the material distribution device to limit multiple groups of sanitary napkins. By providing a limit device, the height and distance of the two groups of limit plates can be adjusted to limit sanitary napkins of different sizes and quantities, thereby ensuring that the sanitary napkins maintain consistency in position and direction before being transmitted to the packaging device, avoiding the situation where packaging defects due to displacement occur, thereby effectively improving the applicability of the equipment.
