Principle
The Ultrasonic Plastic Welding Transducer With Booster is composed of an ultrasonic transducer and an ultrasonic horn to form an ultrasonic vibration system. Ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. Ultrasonic horn is a passive device that does not generate vibration. It only changes the amplitude of the vibration input from the ultrasonic transducer and then transmits it. Impedance transformation.
The Ultrasonic Plastic Welding Transducer With Booster can generate regular vibration under the excitation of a suitable electric field, and its amplitude is generally about 10 μm. Such an amplitude is not enough to directly complete the welding and processing steps. Therefore, the transducer links a properly designed ultrasonic horn, and the amplitude of the ultrasonic wave can be varied within a wide range, as long as the material strength is sufficient, the amplitude can exceed 100 μm.
When the ultrasonic horn is longitudinally stretched and vibrated, the movement of the particles on the left and right sides of a cross section in the middle is exactly opposite, which is equivalent to the existence of a relatively stationary section. This section is called the node, which is also the best fixed point of the vibrator. Deviation from this node will reduce the working efficiency of the vibrator, commonly known as leakage.
Material:
The Ultrasonic Plastic Welding Transducer With Booster has high sound transmission efficiency, but the material strength is low, easy to crack and screw hole sliding; the steel ultrasonic vibrator has high strength, but the acoustic impedance is relatively large; the titanium alloy ultrasonic vibrator has good comprehensive performance, and the disadvantage is high price and processing. difficult.
Common malfunctions:
The Ultrasonic Plastic Welding Transducer With Booster should be placed in a dry place to prevent the ultrasonic vibration from vibrating the mover, which will affect the normal work. If the ultrasonic vibrator is damp, put it into the oven and set it to dry at about 100 °C for 2 hours or use a hair dryer to remove moisture until the resistance is normal;
Ultrasonic Plastic Welding Transducer With Booster degumming, ultrasonic vibrator degumming, the power output of the ultrasonic power supply is normal, but because the vibrator and the vibrating surface are not well connected, the vibrator will be burned if working for a long time. Ultrasonic vibrator degumming should be repaired or replaced by a professional ultrasonic manufacturer.
