The invention discloses a rotor
spinning power-off integral head leaving
system which comprises a process negative pressure motor, a
machine head controller and a middle section control panel, the process negative pressure motor is connected with a fan,
inertia kinetic energy of the fan is converted into
electric energy through the motor and a process negative pressure frequency converter during power off, and the converted
electric energy is continuously supplied to a
bus of an
electric control system; the
machine head controller controls the winding motor and the
yarn guiding motor. And the middle-section control plate controls the cotton feeding roller. An additional
energy storage device is not needed, the power supply problem of the
electric control system when the rotor
spinning equipment is powered off is effectively solved, the cost is greatly saved, the reliability is improved, the
electric control system continuously works and completes the overall head remaining function when the rotor
spinning equipment is powered off externally, overall head making-up is not needed when rotor spinning equipment is started again, and the efficiency is improved. The labor intensity of workers is greatly reduced, the high-
imitation yarn yield is improved, and the completeness of a power supply system is guaranteed.
