Three layer double servo aluminum foil winding machine

Features:

The three-layer dual-servo aluminum foil winding machine relies on the high-precision control characteristics of servo drive, and is equipped with multiple independent unwinding, tensioning, correction, and pressing mechanisms. It enables the three layers of aluminum foil to be synchronously transported and bonded with equal tension during the winding process, and to be formed together with the insulating paper to form a foil coil that meets the requirements of electrical performance and dimensional accuracy. It is widely used in the winding production of small and medium-sized power transformers, dry-type reactors, distribution transformers and other products, and is a key piece of equipment for realizing the large-scale and high-precision manufacturing of foil coils.

    Advantages:

    • High-precision winding: The dual-servo system provides precise speed and position control, coupled with three independent correction systems, ensuring consistent tension across the three layers of aluminum foil, resulting in coils with high precision and stable quality.
    • High-efficiency production: Three layer double servo aluminum foil winding machine can wind three layers of aluminum foil simultaneously, significantly improving production efficiency compared to single-layer or double-layer winding machines. The cold-press welding device offers fast welding speeds and eliminates cooling time, further enhancing overall production efficiency.
    • Easy operation: Three layer foil winding machine features a rational structural design, clearly defined functions for each component, and a certain degree of automation, making it easy for operators to learn and maintain.
    • Strong adaptability: Three layer double servo synchronous foil winding machine can adapt to different specifications of aluminum foil materials and coil winding requirements, such as aluminum foil of varying widths and thicknesses, as well as various coil shapes including round, elliptical, and rectangular.
