the PLC control system is started, all equipment starts to operate or is in a state of waiting to operate, a steel coil is placed on the uncoiler 1, the central line of the steel coil is overlapped with the central line of the utility model by the uncoiling push oil cylinder 103 (the displacement needing to be adjusted is small, so the position of the lifting device is not affected), the output end of the uncoiling oil cylinder 108 retracts, the pull rod 107 drives the sliding sleeve 109 to retract, the sliding sleeve 109 drives the steel lamella to expand, the diameter of the reel 104 is increased, the steel coil is fixed, meanwhile, the supporting oil cylinder 114 is started, the supporting plate 115 is driven to rotate by the first driving plate 116 and the second driving plate 117, the end cover of the reel 104 is supported by the supporting plate 115, the pressing oil cylinder 119 is also started, the pressing oil cylinder 119 retracts to drive the driving shaft 120 to rotate, and the pressing roller 121 on the pressing arm 1202 is pressed on the steel coil to form pressure on the steel coil.

The uncoiling motor 105 rotates, the end part of the steel coil enters the traction mechanism 2 along the platform in front of the uncoiling machine 1, the steel plate at the front end is low in front and high in back, and is slightly bent, so that the dislocation arrangement of the upper traction roller 201 and the lower traction roller 202 can correct the bent part, if the steel plate is not bent, the first hand rocking wheel 211 is shaken to enable the front reverse bending roller 203 to push upwards, the reverse bending roller 203 is only used when needed, otherwise, the reverse bending roller 203 is in a low position state and cannot push the steel plate, then the steel plate passes through the head aligning scissors 3, the head aligning scissors 3 cut the end part of the steel plate orderly, the steel plate enters the rear swing bridge 4 part, at the moment, the first transition plate 406 is in a rising state, the steel plate enters the clamping device 5 after passing through the first transition plate 406, the end part of the steel plate is clamped, at the moment, the lifting motor 411 in the first transition pit 401 is started to drive the first transition plate 406 to fall to the bottom of the pit, under the action of the self gravity of the steel plate, the steel plate falls into a first transition pit 401 through a rear transition frame 4022, then rises back through a front transition frame 4021, enters a clamping device 5, enters a pinch device 502 through the guide of a guide device 501, judges whether the steel plate is positioned at the center position through a displacement sensor when passing through the guide device 501, then a guide motor 5013 automatically adjusts according to an instruction, and is conveyed into a longitudinal shearing host machine 6 through the pinch device 502, the longitudinal shearing host machine 6 is provided with a cutter 602 and a spacing block 603 according to the required width of a steel coil, the cutter 602 cuts the steel plate into the required width, the cut waste edge enters a waste edge coiler 7, an output of a control oil cylinder 704 is controlled, a support bent frame 707 tilts up, the waste edge is wound on a support leg 706 along with the rotation of a rotating disc 705, the tilting part of the support bent frame 707 plays a supporting role, and the rest part enters a front swing bridge 8 along a transition carrier roller 701, at this time, the second transition oil cylinder 802 is in an extending state, the second transition plate 803 is also in a horizontal state, and the steel plate is transited from the second transition plate 803 to the fixed separation frame 9: the steel plate firstly bypasses a steering roller 902, passes through the upper part of a separation 901 at the rear edge and then passes through the lower part of a lower pressing roller 905, then passes through the separation roller 901 at the front edge, enters a tension mechanism 10, is tightly pressed by a fixing plate 1001 and a felt 1003 on a lower pressing plate 1002, the output end of a second transition oil cylinder 802 retracts, a second transition plate 803 is turned over, the cut steel coil droops into a second transition pit 801 to be transited under the action of self gravity, and the steel plate passes through the tension mechanism 10, then passes through a guide workbench 11 and finally enters a winding machine 12 to be wound, so that the longitudinal shearing and winding work is completed.

Other technical features than those described in the specification are known to those skilled in the art.
