This invention relates to an automatic moxa wool feeding machine for moxa stick production, comprising a connecting frame, a transmission mechanism on the inner wall of the connecting frame, and a conveyor belt sleeved on the outer side of the transmission mechanism. In use, the vertical plate is lowered so that its bottom abuts against the top of the conveyor belt to cut the moxa wool. By rotating the vertical plate, the cutting effect of the vertical plate can be optimized, thereby allowing for better separation of the moxa wool to be compacted from the moxa wool currently being compacted. A rectangular plate, the connecting frame, and a pair of vertical plates cover and seal the moxa wool being compacted, preventing it from flying into the air during compaction. Simultaneously, the vertical plates also limit the moxa wool being compacted, preventing it from being squeezed out from both sides of the extrusion plate. Therefore, this invention not only prevents workers from sucking in the moxa wool but also reduces the loss and waste of moxa wool.
