High Frequency Ultrasonic Welding Power Supply Plastic Welding 

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.

Generator part

Intelligent fan control: When the temperature is low, the fan starts following the ultrasonic output. If there is no ultrasonic output within 30 seconds, the fan stops to prevent inhalation of excessive dust and improve the reliability of the device.

When the high temperature exceeds 45 ° C, the fan will continue to work to cool down.

When the temperature exceeds 80 ° C, the device will provide over-temperature protection and prompt on the screen.

Power limitation: In order to be able to work continuously around 2000W, the actual power protection threshold of the generator is 2400W,

Our universal ultrasonic generator is particularly suitable for continues applications such as cutting and non-woven welding. The built-in circuit provides a purer sine wave drive transducer than most generators on the market, making the heat generation less and efficiency higher. Reduce heat dissipation requirements and extend life.

Working mode: automatic mode: continues mode, suitable for cleaning / cutting / non-woven welding, etc. 

For ultrasonic mask slicer , we introduce and suggest the auto model with continues welding only.

Welding machine mode: mode adjustment mode;

  Time mode;

  Energy mode;

  Peak power mode.

Voltage: 198-242VAC (50 / 60Hz), the output will be much weaker when AC110V input, need some adjustment, direct use is almost only used for cutting applications.

Volume: 384mm * 240mm * 110mm

Weight: 7KG

Color: light gray  

Features:

Automatic frequency tracking: The system automatically tracks the resonance frequency of the welding horn. Compensate for detuning caused by heat and other reasons.

Digital frequency control: The operating frequency is digitally controlled by the microcontroller.

Digital amplitude setting: This feature allows users to set precise amplitudes according to application requirements, which provides a larger range and repeatability of settings than analog systems.

The amplitude can be adjusted in a large range: 1% ~ 99% continuously adjustable, which is different from the shortcomings of traditional generators that are difficult to work with low amplitude.

High-speed micro-controller: The internal micro-controller operates at a frequency of up to 168MHz, which can accurately and timely control the working conditions.

Control and sampling interval of 0.5 milliseconds: 2000 times of sampling and control for welding process per second.

Color touch screen display: Through the color screen and touch, friendly and easy-to-use human-computer interaction is realized, and the experience is better.

Coexistence of buttons and touch: common functions can provide better interaction through buttons. Among them, the buttons use silicone keys, which have a better feel.

Operating language: The user can select the applicable language in the start screen: currently only supports English and Chinese.

Slant start: Ultrasonic energy supply and welding horn start at the most suitable ascent speed to reduce the electromechanical pressure of the system.

Vibration after welding: The user can start the ultrasonic after the welding and pressure holding process is finished, and the workpiece sticking to the welding horn will be shaken off.

Welding quality monitoring: user-definable process alarm. When it is outside the range of user-defined defective products, the system will generate an alarm to remind
