[0015] (Three) beneficial effects

[0016] One, multiple variable frequency motors are started simultaneously, the input shaft of the reduction gear box will be rotated by the variable frequency motor, after the transmission of the internal gear of the reduction gear box, the output shaft of the reduction gear box will reduce the rotating speed of the variable frequency motor to drive the first sprocket to rotate, the first sprocket will drive the second sprocket to rotate through the chain, and the second sprocket will drive the roller to rotate, so that the glass can move in the annealing lehr.
