Description

Technical Field

[0001] The invention relates to the field of transformer manufacturing equipment, and in particular to a multi-head uncoiler. Background Art

[0002] The uncoiler is a commonly used equipment in metal coil processing, which is used to unwind the metal coil to facilitate subsequent shearing processing.

[0003] The existing uncoilers only have single-head uncoilers and double-head uncoilers. The single-head uncoiler has only one uncoiler head and no material preparation station. When the coil is reloaded or the coils of different specifications are switched, the entire line needs to stop working, the original coil is removed, and then the coil of another specification is placed on the uncoiler. During production, it is necessary to frequently stop the machine for loading and changing materials, which is time-consuming, labor-intensive, and inefficient. The double-head uncoiler has only one material preparation station, and less material is prepared at a time. When more coil specifications are required, it is impossible to realize simultaneous loading and rapid switching of multiple specifications. In the existing double-head uncoiler, each uncoiler head is driven by an independent motor, which is costly and large in size, and is not suitable for the power layout of a multi-head uncoiler.
