Industrial Ultrasonic Welding Transducer For Welding Abs Pp Non Woven Bags Fabric Sealing Machine

The function of an ultrasonic transducer is to convert electrical signals into mechanical vibration signals. There are two physical effects of converting electrical signals into mechanical vibration signals. A: Magnetostrictive effect. B: The inverse effect of piezoelectric effect. The magnetostrictive effect is commonly used in early ultrasonic applications, with the advantages of high achievable power capacity and the disadvantages of low conversion efficiency, difficulty in production, and difficulty in large-scale industrial production. Since the invention of piezoelectric ceramic transducers, the application of the inverse effect of piezoelectric effect has been widely adopted. Piezoelectric ceramic transducers have the advantages of high conversion efficiency and mass production, but their disadvantage is small power capacity. Existing ultrasonic machines typically use piezoelectric ceramic transducers. A piezoelectric ceramic transducer is formed by clamping the piezoelectric ceramic between two metal front and rear load blocks and tightly connecting them with screws. The output amplitude of a typical sensor is approximately 10 μ M.

The ultrasonic transducer is the core component of a welding machine, mainly composed of a vibrator and an amplitude modulator. Its function is to convert electrical energy into mechanical energy through the simple harmonic vibration of the vibrator itself and drive the entire transducer to resonate under the excitation of electrical signals. The transducer oscillator adopts a sandwich structure, consisting of pre-stressed bolts that clamp the front and rear drive blocks, piezoelectric chips, and electrode plates. The front drive block and amplitude modulator are assembled through connecting screws.
