Coil unloading method of coiler with jaw

The invention relates to a coil stripping method of a coiling machine with a jaw, which comprises the following steps: after a coil stripping trolley touches a coil, a winding drum shrinks to enable the jaw to loosen a strip head, the winding drum of the coiling machine clockwise rotates by about 30 degrees (adjustment is performed according to the depths of the jaws of different winding drums), so that the strip head goes out of the 2/3 position of the jaw of the winding drum, the diameter of the winding drum is expanded, the upwarp angle of the strip head is reduced, and the diameter of the winding drum is reduced again; the coiling block of the coiling machine clockwise rotates about 30 degrees, so that the strip head is completely separated from the jaw, the coiling machine expands the diameter again, the strip head is flattened, after the coiling block shrinks the diameter, the outer support is opened, and the coil stripping trolley supports the steel coil to move out of the coiling block at a low speed
