Special energy-saving controller of plastic filament collecting machine and application method

The invention provides a special energy-saving controller of plastic filament collecting machine and an application method and belongs to the field of chemical and plastic product processing technology. By use of a frequency converter and a special transformer, disadvantages of other technology are overcome, separate control for torque and rotation speed of a torque motor is achieved, the torque or the rotation speed of the torque motor can be individually adjusted, and reeling requirements on different materials and different specifications of plastic weaving filaments are met.
