The drum motor 615 rotates to drive the drum 613, the steel coil fastened to the drum 613, and the pressing roller 522 to rotate in opposite directions and at the same linear velocity, so that the outer steel sheet passes through between the steel coil and the pressing roller 522. When the outer steel sheet provided by the uncoiler 1 reaches a preset length (slightly larger than the perimeter of the steel coil), the shearing machine 3 works to shear the outer steel sheet, the uncoiler 1 stops to enable the outer steel sheet to form a tail at the shearing position, when the tail of the outer steel sheet passes through the glue sprayer 4, the glue sprayer 4 sprays hot melt glue on the tail of the outer steel sheet, and finally the tail of the outer steel sheet is conveyed to the position of the pressing roller 522 by the conveying roller way 5 and is adhered to the outer side face of the head of the outer steel sheet, so that the outer steel sheet of the steel coil is wrapped.

After the wrapping is completed, the swing cylinder 521 operates to make the swing roller table 52 in a vertical position. The translation motor 632b rotates to drive the translation trolley 632 to move rightwards, and when the steel coil reaches a preset position, the lifting oil cylinder 626 works to drive the steel coil to descend and fall onto the steel coil conveying chain.
