What's ultrasonic generator?
Ultrasonic generator, usually called ultrasonic power supply. Its function is to convert our mains (220V 110V or 380V, 50 or 60Hz) into a high frequency AC signal that matches the ultrasonic transducer. From the form of the amplifying circuit, a linear amplifying circuit and a switching power supply circuit can be used, and the high-power ultrasonic power source generally adopts a circuit form of a switching power supply in terms of conversion efficiency. Linear power supplies also have their own application range, which has the advantage that the circuit can be not strictly required.
Matching allows the operating frequency to change continuously and continuously. From the current situation in the ultrasound industry, ultrasonic generators are mainly divided into self-excited and separate excited power supply.
The principle of the ultrasonic generator is to first generate a signal of a specific frequency by a signal generator, which may be a sinusoidal signal or a pulse signal. This specific frequency is the frequency of the transducer, and is generally applied to ultrasonic in an ultrasonic device. The frequency is 20KHz, 25KHz, 28KHz, 33KHz, 40KHz, 60KHz,70khz, 100KHz.
Our ultrasonic generator PCB can be used for non-woven bag making machine, paper cup sealing machine, three layers bag making machine, medical cloths making machine, plastic welding machine, plastic bag making machine,etc.
Ultrasonic welding generator features:
1. High stability: The ultrasonic welding generator adopts all-digital integrated circuits and imported high-performance anti-interference processors. It reduces the number of components, simplifies the hardware structure, and increases the voltage regulation function to improve the reliability and stability of the system.
2. Frequency automatic tracking: digital frequency synthesis technology combined with digital phase-locked loop frequency tracking composite control technology can eliminate temperature, static load, processing area, tool wear and other factors drifting conventional analog regulator is difficult to overcome shortcomings, is conducive to parameter adjustment. It is convenient to modify the control scheme and implement various new control strategies through the modification of the program software.
3. Strong output: It uses IGBT power module plus its exciting oscillating circuit structure, so that the output power is more than 1.5 times that of the traditional self-excited circuit.
4. Amplitude stepless adjustment: the amplitude can be increased or decreased in the process of adjustment, and can also be fine-tuned, effectively preventing the size of the plastic parts can be perfectly welded, and effectively reducing the penetration, burns and so on. The setting range of defective product is 10%~100%.
5. Intelligent protection and fault alarm prompt: This ultrasonic generator has mold current too high protection, frequency offset protection, total output too large protection. When the equipment fails, the generator will immediately stop working and prompt the corresponding fault cause until the technician removes the fault.
Application: Plastic, Toys, Electronic products, Non Woven products, Shore cover, Surgical products, lable, paper cups, mask, etc.
