For the expansion and contraction part where the material coil is installed, the oil cylinder extends and retracts back and forth to expand the tiles supporting the material coil to realize the clamping of the material coil. The brake is a disc brake. The material rack is equipped with pressing wheels. After the coil material is loosened, it will not uncoil and get disordered. At the middle position between the material rack and the leveling part, 3 photoelectric sensors are installed to control actions such as the start, uniform operation, and stop of the uncoiling of the material rack. There is an inlet guiding arc 22 mechanism at the inlet of the leveling part. A second oil cylinder 5 is installed outside the support material rack. A hydraulic station motor 6 is installed outside the uncoiler. A material arc detection switch 14 is installed on the left side outside the support material rack.
