The invention discloses a detachable warp knitting machine pan head. The detachable warp knitting machine pan head comprises a pan head body; the pan head body comprises a winding reel, annular retaining sides sleeve the outer walls of the two ends of the winding reel in an insertion manner, a rotating shaft sleeve is arranged in the winding reel in inserting and sleeving manners, radially extending protruded drum part is arranged on the outer wall of the middle part of the rotating shaft sleeve, a friction sleeve is fixed on the outer wall of the protruded drum part, the outer wall of the friction sleeve is pressed on the inner side wall of the middle part of the winding reel, the two end part connecting sleeves are spirally connected with the two ends of the winding reel, the inner end face of each end part connecting sleeve is pressed on the end face of the protruded drum part, an oblong groove with a cambered-surface section is formed in the inner side wall of the rotating shaft sleeve, an insertion slot is formed in the outer wall of a beam, an elastic mechanism is fixed at the bottom surface of the insertion slot, a limit block is arranged in the insertion slot in the inserting and sleeving manners, and an arc-shaped end part of the limit block is arranged in the oblong groove in the inserting and sleeving manners. The detachable warp knitting machine pan head has the advantages that the maintenance cost is low; the telescopic limit block is arranged on the beam, so that the synchronous operation of the beam and the pan head is ensured; furthermore, when the pan head and the beam are clamped, the pan head and the beam generate relative sliding.
