The Symmetrical Lifting Device in the Pulley System of the Ring Spinning Frame

In order to solve the problem of the transmission accuracy drop due to error accumulation produced by the long pieces of the ring frame,through the modification of the lifting device of the stationary pulley system into the symmetrical lifting device with movable pulley system,the stress condition of the motor and gearbox is improved with good transmission accuracy and longer service life of the motor and gearbox,thus more suitable for the configuration of spinning frame with excess length.
