The machine adopts the German Siemens PLC control system, 10" touch screen, the uncoiler adopts servo motor drive, equipped with gear reducer; four sets of Siemens vector inverter and servo motor control the main traction and automatic winding tension; when the meter reaches the meter, it will automatically decelerate and stop. When unwinding to a small diameter, it will automatically decelerate and stop, and automatically calculate the diameter of rewinding and unwinding. The diameter tolerance is ±1mm. The rewinding method is central surface rewinding, or single-axis rewinding. The rewinding shaft adopts pure aluminum foil special air expansion shaft or machinery Shaft. The slitting adopts straight knife or disc knife, and the corresponding knife can be selected for different thickness materials, and the slitting width can be adjusted at will.
