The utility model relates to a quick disassembly type rib knitting
machine which comprises a rib knitting
machine body, a rotating frame, a winding
assembly and a
rotating drum, the rotating frame is rotationally connected to the rib knitting
machine body, the winding
assembly comprises two rotating discs and a driving part, the rotating discs are rotationally connected to the rotating frame, clamping grooves are formed in the side walls of the rotating discs, and the clamping grooves extend in the radial direction of the rotating discs; the
rotating drum is used for being clamped in the clamping groove, a limiting piece is arranged on the
rotating disc and comprises a limiting plate, a first
magnet and a second
magnet, the limiting plate is rotationally connected to the
rotating disc, the first
magnet is arranged on the limiting plate, the second magnet is arranged on the
rotating disc, and when the first magnet and the second magnet attract each other, the limiting plate is used for abutting against the side wall of the
rotating drum; the driving part is used for driving the two rotating discs to rotate at the same speed. The equipment has the effects that the replacement speed of the rotary drum is increased, so that the working efficiency of the equipment is improved.
