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. The collapsible cylinder 614 operates to drive the spool 613 to collapse, reducing the radius of the spool 613. The translation motor 632b rotates to move the translation trolley 632 to the left, so that the winding drum 613 is drawn out from the core of the steel coil. The lifting cylinder 626 works to adjust the height of the winding drum 613 so that the axis of the winding drum 613 coincides with the axis of the next steel coil on the steel coil conveying chain, so as to start the wrapping of the steel sheet outside the next steel coil.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
