The working principle of the transmission system of the first frying pan is as follows: after the motor shaft of the first motor 311 is acted by the first reduction gearbox 312, the speed of the first motor 311 is reduced to a proper rotating speed, and then the first transmission shaft 12 is driven to rotate, and at the moment, the frying pan main body rotates along the central shaft thereof by self because the first transmission shaft 12 is fixedly connected with the frying pan main body 1; after the motor shaft of the second motor 321 is acted by the second reduction gearbox 322, the speed of the second motor 322 is reduced to a proper rotating speed, then the second transmission shaft 13 and the rotating shaft 3237 of the contact sensor 323 are driven to synchronously rotate, after the wok body 1 moves to an accurate station, the common end on the contact sensor 323 is communicated with the first wiring terminal 3233, the second wiring terminal 3234 or the third wiring terminal 3235, and a communicated signal is sent to the controller, and the controller can directly send a signal to the second motor, so that the second motor stops moving. After the frying pan main body works at a certain station, the controller sends a next control signal to the frying pan main body to control the motor to work. In addition, in the whole motor movement process, the first limit groove 6224 is matched with the first limit column 631, and the second limit groove 6225 is matched with the second limit column 632, so that the limit can be respectively carried out at two ends of the maximum stroke of the motor movement, and the second motor is ensured not to drive the frying pan main body to move beyond the stroke range, thereby causing irreparable loss. It should be noted here that, by using such a physical limiting manner, the second motor may be burnt, but the maintenance cost for replacing the second motor is relatively low.
