An apparatus for processing an ai-branch

The present application relates to the field of wormwood processing, and more particularly to a device for processing moxa sticks. The technical problem to be solved is that the moxa is light in quality and easy to scatter, resulting in waste of a portion of the moxa, and that the air in the gaps between the moxa cannot be promptly removed during the compaction of the moxa, resulting in the moxa not being compacted tightly, reducing the tightness of the moxa sticks, making it difficult to control the thickness of the glue on the wrapping paper, and thus causing the wrapping paper to be damaged due to excessive glue in some parts, and reducing the packaging quality of the moxa sticks. The technical solution is a device for processing moxa sticks, comprising a support frame and a winding roller, etc.; the support frame is connected with a left-right movable winding roller. The present application turns the folded corners out by means of the flattening plate, simultaneously flattens the corners by means of the pressure roller and the glue roller, and makes the wrapping paper between the pressure roller and the glue roller flat without being raised, so as to facilitate the glue outlet nozzle to spray glue to the corner, thereby avoiding the corners of the wrapping paper from being delaminated, and ensuring the packaging quality of the moxa sticks.
