Introduction:

 　　 The function of the ultrasonic transducer is to convert the input electric power into mechanical power (ultrasonic) and then transmit it out, while it consumes a small part of the power. For the ultrasonic transducer, the technical problem to be solved is to design an ultrasonic transducer with a large working distance and a wide frequency band. The transducer is composed of a shell, a matching layer, a piezoelectric ceramic disc transducer, a backing, a lead-out cable and a Cymbal array receiver. The piezoelectric ceramic disc transducer is made of PZT-8 piezoelectric material polarized in the thickness direction. The Cymbal array receiver is composed of 8-16 Cymbal transducers, two metal rings and rubber washers. The operating distance of the invention is greater than 35m, the frequency bandwidth reaches 10kHz, and it can detect the long-distance target moving at high speed.

  　　 Application range of ultrasonic plastic welding machine:   　　Automotive industry: (Traffic industry) Ultrasound can be controlled by computer programs to weld large and irregular workpieces such as bumpers, front and rear doors, workbenches, lamps, brake lights, etc. With the development of high-grade roads, more and more ultrasonic welding is used for reflectors.   　　Electronics industry: using automation scheme design to enable users to achieve large-scale production while ensuring product quality   　　Packaging industry: food packaging, hose sealing, connection of special packing belts.   　　 water purification filter element: Ultrasonic filter element welding machine is aimed at unfolding the microporous membrane. The end cover of the filter element is welded without water leakage and air leakage, and can be welded airtight.   　　Ultrasonic medical filter welding machine, special ultrasonic welding machine for filter element, ultrasonic filter end cap welding machine, ultrasonic PP filter welding machine   　　 Ultrasonic filter element machine is simple to operate and has a beautiful appearance. It is suitable for mass production. It is a filter element manufacturer’s   　　Ultrasonic spot welding machine is suitable for riveting welding process of automobile instrument panel and automobile door panel   　　 The composition of the ultrasonic transducer: The transducer is composed of a shell, a matching layer, a piezoelectric ceramic disc transducer, a backing, a lead cable and a Cymbal array receiver. The piezoelectric ceramic disc transducer is made of PZT-8 piezoelectric material polarized in the thickness direction. The Cymbal array receiver is composed of 8-16 Cymbal transducers, two metal rings and rubber washers. The piezoelectric ceramic disc transducer is used as a basic ultrasonic transducer, which transmits and receives ultrasonic signals; the Cymbal array receiver is located on the disc piezoelectric transducer as an ultrasonic receiver for receiving the disc Doppler echo signal outside the transducer frequency band. The operating distance of the invention is greater than 35m, the frequency bandwidth reaches 10kHz, and it can detect the long-distance target moving at high speed.
