[0033] Working principle and usage process of this utility model:

[0034] First, the worker inserts the aluminum coil to be uncoiled into multiple inner support members 22 to fix the aluminum coil to the frame 1; after starting, the motor 26 drives the screw 25 to rotate around the threaded cylinder 24 axially, which in turn drives the rotating drum 21, which is rotatably connected to one end of the screw 25, to move along the threaded cylinder 24 axially. The moving rotating drum 21 causes the angle between the axial direction of the second connecting plate 211 and the axial direction of the connecting rod 23 to change. At the same time, the angle between the axial direction of the connecting rod 23 and the axial direction of the first connecting plate 222 also changes. At this time, the distance between the multiple inner support members 22 and the rotating drum 21 changes until the circumferential side of the inner support member 22 is completely in contact with the aluminum coil.

[0035] This effectively prevents the aluminum coil from deforming due to the loosening of the inner ring during the uncoiling process, maintains the flatness of the material, and evenly distributes the stress inside the aluminum coil, reducing material damage caused by stress concentration. In addition, by setting the screw 25 and the threaded cylinder 24, multiple inner support members 22 can adapt to aluminum coils with different inner diameters, improving the versatility of the equipment.

[0036] Subsequently, the worker rotates the rotating rod 33, which in turn drives the sliding plate 32, which is threadedly connected to the rotating rod 33, to slide along the moving groove 121 until the pressure roller 31 of the mounting column 321 installed on the sliding plate 32 comes into contact with the side of the aluminum coil. In this way, by setting the pressure roller 31, the aluminum coil is ensured to remain stable during the uncoiling process, avoiding material damage caused by vibration and swaying.

[0037] After the aluminum coil is fixed, the rotating motor 29 drives the rotating column 28 to rotate, which in turn drives the rotating frame 27, which is fixedly connected to the rotating column 28, to rotate around the axis of the rotating column 28, so that the multiple inner support members 22 and the aluminum coil attached to the inner support members 22 rotate synchronously, thereby completing the uncoiling operation.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
