NOMURA Foil Wrapping Machine

In the field of transformer manufacturing, different specifications of transformer foil coils have diverse requirements for winding equipment. As an influential enterprise in the industry, NOMURA Automation Technology (Suzhou) Co., Ltd. has developed and produced the Yeyi foil winding machine, which, with advanced technology and flexible configuration, can excellently adapt to various specifications of transformer foil coil winding tasks.

The NOMURA foil winding machine fully considers the adaptability to different specifications of coils in its structural design. Taking its unwinding and feeding system as an example, the system is equipped with an adjustable unwinding device that can adapt to foil rolls of different sizes. Through high-precision mechanical adjustment mechanisms, operators can easily adjust the length and expansion/contraction range of the feeding cylinder of the unwinding device to meet the installation requirements of foil rolls with different widths and inner diameters. Whether it is narrow width small transformer foil or wide width large transformer foil, the unwinding device of NOMURA foil winding machine can stably support and release the foil. At the same time, the feeding device adopts advanced servo motor drive technology, which can accurately control the feeding speed and amount of foil according to preset parameters. When faced with winding coils of different specifications, simply input the corresponding parameters in the control system, and the feeding device can quickly make adjustments to ensure that the foil enters the winding area at the appropriate speed and tension, providing a stable material supply for the subsequent winding process.

The tension and correction system is one of the key technologies for the Yeyi foil winding machine to achieve flexible adaptation to coils of different specifications. In terms of tension control, the equipment adopts advanced segmented tension control technology. By analyzing foil materials of different thicknesses and materials, NOMURA foil winding machine can intelligently select the appropriate tension control mode. For thin and narrow foil materials, the air compression dynamic tension method is adopted, and the working air pressure of the air compression actuator is precisely controlled by an electrical proportional valve
