Description:
1. The BRJ series dual-layer transformer foil winding machine is a specialized equipment for winding foil-type low-voltage coils. The entire machine integrates foil uncoiling, photoelectric edge detection and correction, foil cutting, interlayer insulation, main shaft winding, and welding into one unit.
2. Equipped with two independent mechanical expanding mandrel uncoiling units, capable of simultaneously loading two layers of copper or aluminum foil. Two sets of interlayer and end insulation unwinding mechanisms support single or dual-layer foil winding modes.
3. Features two independent torque motor-based tension control units, compatible with different materials such as copper and aluminum foil. Tension deviation between the two foil layers is ≤±1%, preventing inconsistent tension.
4. Two independent photoelectric edge detection systems combined with precision lead screws enable high-accuracy, fast-response edge correction, ensuring continuous alignment of both foil edges and flat, smooth coil end faces.
5. Two independent disc shear units cut the foil material without stretching deformation, producing clean, burr-free cut ends.
6. The rewinding unit is equipped with a high-power motor and gearbox, delivering stable winding torque. The main shaft is linked with the front dual-layer uncoiling tension system, automatically adjusting output torque in real time as the coil’s outer diameter increases, maintaining consistent tension throughout the entire winding process. Equipped with a flexible lower pressure roller that tightly presses against the coil's outer circumference throughout the winding process, ensuring compact and uniform coil formation.
7. The welding unit uses a Model 500 TIG welder, with the torch moving horizontally via frequency-controlled motor drive, enabling stepless speed adjustment. The weld provides even electrical conductivity, smooth surface finish, and no slag or burrs. The entire unit can be electrically moved left or right to enter or exit the welding work area.
8. Heavy-duty welding frame, stress-relieved by annealing, ensuring long-term heavy-load operation without deformation.
9. The control system is PLC-based with a 10-inch touch screen, supporting seamless switching between manual and automatic modes.
