[0039] The pulling member comprises: The guide block 603 is movably placed through the opening provided on the top surface of the hollow cover 6; The guide block 603 is fixedly connected to the fixed end of the telescopic rod 601; The pull rope 605 passes through the inner sleeve of the guide block 603 and is connected to the guard plate 506; The retaining ring 606 is fixed on the spring leaf 505 and is located near the telescopic rod 601; The pull rope 605 movably passes through the inner side of the retaining ring 606; Specifically, the opening on the top surface of the hollow cover 6 can provide a moving guide for the guide block 603 , the guide block 603 can support one end of the pull rope 605 , and the retaining ring 606 can provide a resisting effect for the pull rope 605 under the support of the spring leaf 505 .

[0040] In actual application of this embodiment, when the guard plate 506 is pushed by the aluminum coil, the guard plate 506 will pull the pull rope 605 under the action of external force, so that the pull rope 605 pulls the guide block 603 to move along the opening toward the direction close to the unwinding roller 1 under the resistance of the retaining ring 606, and at the same time, the guide block 603 will push the telescopic rod 601 under the action of external force, so that the telescopic rod 601 moves along the inner side of the hollow cover 6 toward the direction close to the frame plate 102 under the action of external force. At the same time, the telescopic rod 601 will push the insertion rod 604 to move together under the action of external force and the elastic force of the second spring 602, so that the insertion rod 604 can be inserted into the inner side of the aluminum coil under the support of the telescopic rod 601, the hollow cover 6 and the telescopic plate 5, so that the insertion rod 604, the telescopic rod 601, the hollow cover 6 and the telescopic plate 5 provide positioning support for the aluminum coil; When the position of the insertion rod 604 can only contact the aluminum coil, the insertion rod 604 moves towards the direction close to the frame plate 102. Under the resistance of the aluminum coil, as the telescopic rod 601 moves, the fixed end of the telescopic rod 601 and the insertion rod 604 squeeze the second spring 602, and the telescopic rod 601 shrinks at the same time, so that the insertion rod 604 will not affect the movement of the aluminum coil, or the staff can move the position of the telescopic plate 5 to pull the telescopic plate 5 to extend or shrink, so that the insertion rod 604 can move to the position corresponding to the inner side of the center of the aluminum coil, and then the second spring 602 will use the rebound force to push the insertion rod 604 to insert into the inner side of the aluminum coil under the support of the fixed end of the telescopic rod 601, and at the same time, the insertion rod 604 uses the rebound force of the second spring 602 to stretch the telescopic rod 601.

[0042] Specifically, the frame 3 can provide an opening space for the T-slot 701 under the support of the bracket 103, the support frame 301 can stably support the T-bar 703, the T-slot 701 can provide a moving guide for the T-bar 703, the frame plate 102 can provide a stable support for the electric push rod 7, the electric push rod 7 can be electrically controlled to extend and retract, and the telescopic end can be used to support the connecting frame 702, so that the connecting frame 702 stably supports the frame 3.

[0043] In the actual application of this embodiment, after the arc plate 4 rotates clockwise and adjusts the position of the aluminum coil to a position where it can be mounted on the outside of the unwinding roller 1, the staff can control the electric push rod 7 to retract under the support of the frame plate 102, so that the electric push rod 7 drives the connecting frame 702 to move in the direction close to the frame plate 102, so that the connecting frame 702 drives the support frame 301 to move backward under the action of external force, and at the same time, the support frame 301 will drive the T-bar 703 to move backward along the T-slot 701 under the support of the frame 3 under the action of external force, and then the support frame 301 drives the rolling part, the guard part and the fixed rolling part to move backward under the action of external force, and at the same time drives the aluminum coil that is collected, supported and positioned to move and be mounted on the outside of the unwinding roller 1 for unwinding; At the same time, the pressure of the pressure roller 305 can make the aluminum coil mounted on the outside of the unwinding roller 1 contact with the unwinding roller 1.
