Automatic deviation rectification control and detection system for tunnel type microwave drying device

The utility model discloses an automatic deviation rectification control and detection system for a tunnel type microwave drying device. The automatic deviation rectification control and detection system comprises a drive roller rotatably installed on a conveying rack, wherein a conveying belt is arranged on the drive roller, conveying belt deviation detection sensors are oppositely installed on the conveying rack at two ends of the drive roller, a deviation rectification controller is installed on the outer side of the conveying rack, the conveying belt deviation detection sensors are connected with the deviation rectification controller, and a conveying belt adjustment device is installed on the conveying rack and is connected with the deviation rectification controller. The conveying belt deviation detection sensors can detect the position of the conveying belt in real time and output signals to the deviation rectification controller once deviation occurs, the deviation rectification controller sends a control signal to the conveying belt adjustment device to perform automatic deviation rectification so as to ensure that the conveying belt is always in an initial starting state in the operating process and is prevented from being rubbed with the rack or a microwave heating box, protection of the conveying belt is facilitated, and the service life of the conveying belt is ensured to the maximum extent.
