When the output frequency of the ultrasonic lace machine of Changzhou Jiapu mechanical equipment Co., Ltd. does not match the frequency of the transducer, it will not only affect the experimental results, but even damage the equipment when the deviation is large. Therefore, we use frequency tracking technology to make the output frequency of ultrasonic generator consistent with the frequency of transducer, so as to ensure the quality of stitching and embossing, and greatly extend the life of ultrasonic generator and transducer device; frequency scanning technology: through frequency scanning technology, all transducers have the opportunity to work at the resonance point, so that the load of ultrasonic transducer Equilibrium.
