• an upward pushing device disposed beneath the feeding position and comprising a plurality of pushing members corresponding to the rotation arms for pushing the cotton section upward into the holding barrel;
• and
• a downward pressing device disposed above the outputting position and comprising a plurality of stamping members corresponding to the rotation arms;
• when the holding barrel containing the cotton section rotates from the feeding position to the outputting position, and the holding barrel is in positional alignment with one of the stamping members and one empty bottle, the stamping member pushes out the cotton section from the holding barrel and inserts the cotton section into the bottle.
