Successively to extend the opening time of magnetron 12.I.e. subsequent microwave power supply 11 and magnetron 12 can be according to rotary encoders 8
Signal is successively opened, and is avoided the occurrence of disposable opening whole magnetron 12 and is resulted in waste of resources, and part microwave heating cavity 1 goes out
Existing 12 internal element service life of zero load phenomena impair magnetron.
When detection switch 7 is returned without signal value, illustrate there is no slabstone on conveyer belt 9, detection switch 7 will not have at this time
The signal of slabstone is sent to rotary encoder 8, and rotary encoder 8 calculates the operation of slabstone according to runing time and the speed of service
Distance, if counted range ability and control system set distance (have in the set distance and conveyer belt 9 setting of slabstone away from
From difference) it is equal, then magnetron 12 is automatically closed.The process being automatically closed is also successively to be closed according to the signal of rotary encoder 8
It closes, guarantees entire microwave system stable operation.The automatic opening and closing of magnetron 12 of the present invention not only increase slabstone drying
Efficiency also extends the service life of magnetron 12.
The present invention by detection switch 7 automatically detection slabstone and rotary encoder 8 automatically record and calculate slabstone operation away from
From to control the open and close of magnetron 12, realizing the automation control of the open and close of magnetron 12, reduce labor
Dynamic cost improves slabstone drying efficiency, meanwhile, automation control magnetron 12 can extend microwave equipment service life.The present invention
Demonstrating the control method that slabstone detects automatically and magnetron is automatically turned on and closed through scene progress functional acceptance has reliably
Property and feasibility.
The above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to preferred embodiment to this hair
It is bright to be described in detail, it will be appreciated by those skilled in the art that technical solution of the present invention can be modified or be waited
With replacement, without departing from the objective and range of the technical program, should all cover in scope of the presently claimed invention.
