series of foil coil winder

The foil winder is also called foil coil winder. It is the special equipment for the winding of foil coil of the transforme. The EKBR type foil winder of the company applies PLC automatic control frequency conversion stepless speed regulation system, photoelectric liquid corrective system, automatic welding structure and other automatic controlling function to ensure the quality of the wled and greatly reduces the transformer loss. The transformer performance has reached the first level in the domestic industry. The foil winder also market in other 30 countries and districts. The product got high praise among the users for its good performance.

1.The equipment applies the servo corrective system, PLC self-control way, frequency conversion stepless speed regulation system, and therefore it has the features of accurancy correctiveness and precise quality control.
2.The head feed of the equipment applies hydraulic pression collapsible structure and therefore it is more convinient and easy to operate.
3.The tightener of the foil material applies the independant two gear controlling and thus has the features of precision, convinient, and it can maintain the needed tensility of forward wound, stop and unreal to ensure the compaction of the coil.
4.The layer paper tightener applies the gas-expansion axis, and magnetic partical clutch and other advanced equipment, and therefore it is convenient to refuelling and regulate the tensility.
5. automatic welding structure, automatic speed regulation to ensure the high efficiency.
6.the device applies the unit swing mechanism firstly and thus resolve the problem of less coil turns and lagging correcting.
7.the device is the high-tech products developed on the base of practice, it applies the PLC automatic controlling system, and therefore has the features of high automation and easy and reliable operation.
