The invention discloses an anti-deviating energy-saving type microwave vulcanization device achieving stable vulcanization and a using method thereof. The anti-deviating energy-saving type microwave vulcanization device achieving stable vulcanization comprises a support which is provided with a conveying belt, vulcanization tanks are arranged above the conveying belt, a dehumidification device is arranged above each vulcanization tank, a master control device is arranged at the head end of the conveying belt, and a power device is arranged at the tail end of the conveying belt. The master control device comprises a driven shaft, a deviation rectifying device is arranged beside the driven shaft, and an encoder is arranged on the driven shaft. A driving shaft is connected with the driven shaft through the conveying belt. A material sensor is further arranged at the head end of the conveying belt. Magnetrons are distributed in the vulcanization tanks, and temperature sensors are arranged between the magnetrons. Spray nozzles are further arranged above the magnetrons. The deviation rectifying device comprises a deviation rectifying motor which is connected with a sliding block, the sliding block is connected with an adjusting roller, and travel switches are further arranged on the two sides of the conveying belt correspondingly. The anti-deviating energy-saving type microwave vulcanization device achieving stable vulcanization and the using method thereof have the characteristics that energy consumption is reduced, the service life is prolonged, the equipment utilization rate is increased, and transportation is stable.
