15khz and 20khz Digital ultrasonic welding generator

You are welcome to use the 15khzh and 20kHz ultrasonic plastic welding generator produced by our company. The ultrasonic generator produced by our company, using self excited circuit, can keep track of the change of the transducer parameters and play the most effective of the transducer of the plastic welding machine when working. The stability of the ultrasonic generator is added.

Before commissioning, the generator of plastic welding machine should confirm the frequency of the transducer and the frequency of the generator of the plastic welder before commissioning. If the transducer frequency is 20KHz + 200Hz, the frequency of the generator is also 20KHz + 200Hz. If the frequency is different, it is easy to damage the ultrasonic generator. (the generator and transducer complete sets of machines of our company are well adjusted before they are released from factory. If it is a separate generator, the customer must confirm the frequency of the horn.

1, high stability: all digital integrated circuits, the use of high performance anti-jamming processors in the United States, reduce the number of components, simplify the hardware structure, and increase the voltage stabilizing 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 complex control technology, can eliminate the temperature, static load, machining area, tool wear and other factors drifting conventional analog regulator is difficult to overcome the shortcomings, is conducive to the adjustment of parameters, it is convenient to adjust through the modification of program software. The whole control scheme and the realization of various new control strategies.

3, strong output: the use of IGBT power module plus his shock circuit structure makes the output power more than 1.5 times of the traditional self excitation circuit.

4, amplitude non pole adjustment: the amplitude can be increased or reduced in the process of adjustment, and also can be adjusted. It can effectively prevent the size of the rubber parts from perfect welding and effectively reduce the exciting and scald. Setting range of the amplitude of defective products 10%~100%

5, intelligent protection and fault alarm hints: mold current overprotection, frequency offset protection, total output overprotection. If the equipment fails, the generator will immediately stop working and make corresponding cause for failure until the technician troubleshooting.

6. The amplitude control of the intelligent closed loop amplitude control technology can adjust the amplitude of the amplitude, and keep the constant amplitude output without the influence of the fluctuation of the input voltage and load.
