At present, two modes of realizing feedback of control signals basically exist, one is a mechanical structure control mode as described above, and the other is to adopt an electronic control signal for feedback, and when the electronic control signal is adopted, the motion stroke of the second motor can be directly controlled through a pulse signal. However, if the second motor is blocked and blocked in the movement process, the movement stroke of the frying pan main body is directly inaccurate; if it is desired to increase the accuracy of the electronic control signal, it is necessary to use a motor with greater torque and power or to use a servomotor, which can lead to a sharp increase in the bulk and cost of the overall transmission system, which is why the applicant of the present invention does not consider the use of the electronic control signal for feedback.

The assembly process of the transmission system synchronous feedback adjusting device of the food processing device is as follows: firstly, the second transmission shaft 13 is inserted into the second through hole 623 after passing through the central round hole of the second positioning disk 65, a second locking hole 6211 is arranged on the second small head 621 at a position deviating from the central position, the other end of the second transmission shaft 13 is fixed in the second through hole 623 by driving a screw into the second locking hole 6211, the tightness degree of the second tensioning groove 624 is adjusted, and then the second small head 621 is fixed on the right side of the second positioning disk 65 by the screw; secondly, a second output shaft 3221 of the second reduction gearbox 322 passes through the central round hole of the first positioning disc 64 and then is inserted into the first through hole 613; then the first guide post 6121, the second guide post 6122 and the third guide post 6123 of the universal joint 61 are respectively inserted into the first assembly hole 6221, the second assembly hole 6222 and the third assembly hole 6223 of the limit clamping block 62, so that the universal joint 61 and the limit clamping block 62 are fixed together; then the central axis of the frying pan body 1 is adjusted to the vertical position and fixed, and then the limiting clamping block 62 is rotated, so that the first limiting groove 6224 can be clamped on the first limiting column 631; finally, a locking screw is driven into the first locking hole 6111 of the universal joint 61 and the tightness degree of the first tensioning groove 614 is adjusted.

The working principle of the transmission system of the first frying pan is as follows: after the motor shaft of the first motor 311 passes through the action of 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 the frying pan body automatically rotates along the central axis because the first transmission shaft 12 is fixedly connected with the frying pan body 1; after the motor shaft of the second motor 321 passes through the action of 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, when the frying pan main body 1 moves to an accurate station, the common end on the contact sensor 323 is conducted with the first connecting terminal 3233, the second connecting terminal 3234 or the third connecting terminal 3235, a conducted signal is sent to the controller, and the controller directly sends a signal to the second motor, so that the second motor stops moving. When the work of the frying pan main body at a certain station is finished, the controller sends a next control signal to the frying pan main body to control the motor to work. And, in the whole motor motion process, through the matching of first spacing groove 6224 and first spacing post 631, the matching of second spacing groove 6225 and second spacing post 632, can carry out spacingly at the both ends of the biggest stroke of motor motion respectively, ensured that the second motor can not drive the frying pan main part motion and surpass the stroke scope to cause irreparable loss. It should be noted that, by adopting the physical limiting mode, the second motor is burnt, but the maintenance cost for replacing the second motor is relatively low.
