Main feature：
1. Each uncoiler drives the sprocket through the hydraulic motor, and drives the main engine through the sprocket, so that the steel coil rotates with the main shaft.
2. To achieve the purpose of auto uncoiler, the base and frame of the uncoiler are all welded by rectangular tubes, which fully guarantees the rigidity of the machine.
3. Reel: four pieces of nesting (shoes), available in 508 and 610 sizes, when 508 steel coil is switched to 610 inner hole steel coil, four arc plates are added to the original uncoiler to automatically support Ttght and constant tension control.
4. Transmission system: forward and reverse to realize the rewinding and unwinding, the unwinding mandrel is driven by the motor and the reducer to realize the automatic opening of the steel coil, and it can also be used for the recovery of the plate that has not been processed; when the material is automatically opened, it can maintain same tempo as production.
5. The pressing deviceis to swing the pressing arm through the cylinder. When the cylinder rises, the pressing arm is loosened; when the cylinder is lowered, the pressing arm is pressed tightly. The adjustment of the coil center of the uncoiler is realized by the hydraulic cylinder, which is convenient to adjust and easy to operate; when the coil is automatically uncoiled, the pressing arm must loosen the steel coil, and when the machine stops, the pressing arm must press the steel coil.
6. Lifting trolley: The lifting trolley is driven by the motor to make the trolley walk along the guide rail, and the lifting device is driven by the hydraulic cylinder through the lifting platform for the connecting rod to complete the loading and unloading actions. The lifting platform and the walking platform adopt the mixed welding structure of rectangular tube and steel plate, and the appearance is beautiful.
