Abstract
A cotton stuffing machine includes a roller conveyance device, a rotation device, an upward pushing device, and a downward pressing device. The roller conveyance device inputs cotton and presses and pulls the cotton to deliver a cotton section. The rotation device includes a plurality of rotation arms. Each rotation arm has a holding barrel on two ends thereof, and undergoes a 180-degree rotation displacement between a feeding position and an outputting position. The upward pushing device is disposed beneath the feeding position for pushing the cotton section upward into the holding barrel. The downward pressing device is disposed above the outputting position for pushing out the cotton section and inserting it into the bottle. Thus, the present invention improves the efficiency of stuffing operation for stuffing the cotton into the bottles.
