    2. Features Of LV Foil Winding Machine:

    1.2.1 Tension system, the machine by uncoiling tension, tension system to compare the advantage and the traditional passive tension stability, dynamic and static tension, foil tape and insulating layer with whether there is a tension winding or back on, avoid the loss caused by zhang winding is differ, adjust air pressure size, guarantee the stability of the whole process of winding tension.

    1.2.2 adjusting system adopts photoelectric sensor, through the motor dynamic action, the system of high precision, fast response, can ensure the winding coil end face and tidy.

    1.2.3 Foil belt tension, insulating layer and the parameters of the coil and winding tension state, such as digital setting and display, intuitive and accurate.

    1.2.4 Open book brake motor (linkage), can foil belt tension feedback to winding machine or grid control, brake create tension. The tension is stable and reliable.

    1.2.5 Because using compressed air to generate tension, the whole machine hydraulic system, the whole machine without vulnerability consumable, less point of failure, reduce maintenance cost, less mechanical adjustment point, improve production efficiency, low noise, no pollution of hydraulic mechanical friction, environmental protection.

    3.Advantages

    it is convenient to load and unload gas.

    The whole device is placed in a small car, which can be pulled out as a whole, so as to facilitate the loading and unloading of the material and the adjustment of the cutting edge. The outside of the body is not guided, not taking the place, and the site is neat and beautiful.

    4) the insulation tension of the layer depends on the magnetic powder clutch, resulting in tension control and no noise.

    The size of tension is not specified, and the tension of the winding diameter from large to small is constant.

    The entire device and each reel can be manually adjusted in width direction.

    3. Welding equipment

    1) the welding of foil and lead is adopted TIG welding, and the welding equipment is mainly composed of the following parts: jig, welding gun driving mechanism, welding gun adjustment mechanism, TIG welding machine, cooling water tank, etc.

    2) the open pressure of the clamping part is realized by pneumatic, the welding gun can be adjusted up and down, and the welding gun is driven by frequency conversion motor, and the speed is not adjustable.

    3) the whole device can move (electric) to or from the welding area.

    The welding table can move the Angle (60 degrees) so that the foil belt, especially the thicker foil, can be carried through the clamping part and adjust the welding Angle.

    4. Cleaning device

    On top and bottom felt plate holding foil bring remove foil with metal shavings, dust and other impurities, the mat plate under the action of a cylinder can be up or down, the clamping force can be adjusted through the pressure regulator.

    When the upper plate is clamped tightly, the entire device can float with the foil band, and the whole foil belt can be automatically returned.

    The felt plate body is fixed with screw respectively, but can be removed as a whole to replace the felt.
