General structure of unwinding line:

 The single cantilever type is usually used. If the weight of the raw material is large, auxiliary support should be added to the end of the uncoiler. The uncoiler seat usually has the function of moving forward and backward along the parallel direction of the single machine, which can effectively and quickly complete the raw material alignment.

 A. conical head opening line: the conical head opening frame is suitable for any inner diameter of the original material in the range of cone head to cone tail, but it is generally suitable for medium thick raw material above 3 mm because it is easy to cause damage to the inner ring edge of the raw material.

 B. step unwinding line: the unwinding head of this method is only suitable for multi-standard inner diameter raw materials, generally divided into 2~4 grades, but the operation is relatively not single-headed cantilever intuitive and convenient, its front and rear movement is usually driven by oil cylinder.

 The coiling machine is generally used in the steel coil unwinding and leveling shear production line. The purpose is to re-winding the steel coil after longitudinal cutting, and cutting the width of the original steel coil into several different widths. This kind of unit is also used in the production line of pickling, annealing, shearing and coating of strip steel; this kind of unit is not only used for winding, but also can be used as uncoiling machine. In the process of production line, relying on this kind of unit, the tension before and after can be established, the rewinding steel coil can be beautiful and smooth, and it is convenient for subsequent processing or transportation, thus improving the stability of the production line.

 The working principle of the coiler is introduced by the manufacturer of uncoiling and leveling shearing production line
