In the dynamic world of sheet metal shearing, the velocity of the shearing machine stands as the linchpin in the operational rhythm of the entire production line. Achieving seamless synchronization between the unwinding speed of the decoiler and the shearing machine is pivotal. However, a challenge arises: as the shearing machine maintains a constant speed, the material coil on the decoiler steadily diminishes. This prompts an inevitable rise in the rotational speed of the material stand, where the material is dispensed. Traditionally, a manual approach involves monitoring material height in the feeding pit and manually adjusting the decoiler speed. While effective at slower speeds, this method leads to delayed reactions, causing issues such as material dragging or tension at higher and lower unwinding speeds, respectively. In an era of fierce competition where efficiency is paramount and human intervention must be minimized, this antiquated manual speed-matching process falls short.
