General information Transformer Round Core Winding Machine is equipped with the latest PLC system and HMI touch screen to control the decoiler, winding machine and laser welder. The decoiler feeds the materials to winding machine, the material through the leveling unit, tension unit, guider unit, deburring unit, then machine hand will clamp and feed material from cutting molds to the mandrel, then the servo motor drive the mandrel to wind materials into toroidal core, the laser system welds the end layer with perfect welding spot, at last, the mechanical arm pick up the cores automatically. Main Features of the transformer core winding machine Automatic feeding, punching, winding, cutting, welding and collecting with high speed and efficiency. PLC system and HMI touch screen to control servo motors, moving parts and pneumatic components. Continuous feeding, adjustable tension, accurate counting, closed-loop monitoring, automatic alarm. Automatic laser welding with perfect welding spot, pick up cores by machine hand. Equipped with lifting platform, leveling unit, deburring unit, tungsten alloy cutting mould and air conditioner. Equipped with laser welder, 1 set welder can match upto 1 or 2 or 3 or 4 sets core winders.
