The invention discloses an automatic framing and enclosing set of cocooning frames. The set comprises a transverse feed mechanism (1), a longitudinal feed mechanism (2) and a longitudinal-transverse framing mechanism (3). The transverse feed mechanism and the longitudinal feed mechanism feed transverse strips and longitudinal strips, respectively; protrusions arranged within a holding tray form grid slots; the transverse strips each having an upward slot are fed into the transverse grid slots in one-to-one correspondence; the longitudinal strips each having a downward slot are fed into the longitudinal grid slots in one-to-one correspondence; the fastening slots of the transverse strips are pressed down and fastened into the fastening slots of the longitudinal ribs; each protrusion corresponds to one of grid units formed by the transverse strips and the longitudinal strips; a finished cocooning frame is removed from the holding tray. The automatic framing and enclosing set of cocooning frames has the advantages that automatic framing of cocooning frames is achieved, and framing cost of the cocooning frames is decreased accordingly.
