35Khz Ultrasonic Transmitting Converter For Ultrasound Fabric Sealing Equipment

Ultrasonic Transmitting Converter 35Khz for Ultrasound Fabric Sealing Equipment ​

Description:

The ultrasonic transducer itself is not an energy generator, it is just an energy converter. It converts electrical energy into acoustic energy (mechanical energy), which can convert (output) a large amount of energy under the premise that the input (drive power) and output (amplifier, ultrasonic mold) are well matched. Let the ultrasonic transducer and the ultrasonic generator drive power supply and the ultrasonic mold cooperate well to form a complete ultrasonic device, which can be referred to as matching. Since the impact of matching on the performance of the whole machine is decisive, the importance of matching is not overemphasized. The primary consideration for matching is the capacitance of the transducer, followed by the frequency of the transducer.

Does the ultrasonic welding machine have radiation?

Ultrasound is not a source of radiation and is generally harmless to the human body. We know that when an object vibrates, it emits a sound. The number of vibrations per second is called the frequency of the sound. Its unit is Hertz. The frequency of sound waves that we can hear is 20 to 20,000 Hz. If the vibration frequency of the sound wave is greater than 20,000 Hz or less than 20 Hz, we will not hear it. Sound waves with frequencies above 20,000 Hz are called "ultrasonics". The ultrasonic frequency commonly used for medical diagnosis is 1 to 5 MHz. Ultrasonic waves have good directionality, strong penetrating ability, easy to obtain more concentrated sound energy, and far-reaching distance in water. Can be used for ranging, speed measurement, cleaning, welding, gravel, etc. It has obvious effects in medicine, military, industry and agriculture. High-power focused ultrasound can be used to treat tumors. It can rapidly raise the temperature of target tissue to above 70 °C in 0.5 seconds, so that intracellular proteins can rapidly coagulate. Necrosis (the critical point of tumor cell lethal temperature is 42.5~43.0 °C, while normal cells are 45 °C. For liver tissue, local temperature above 58 °C can cause tissue coagulative necrosis). The local sound intensity is as high as >1 megawatt/cm2 or more. Of course, it may damage the local normal tissue and requires precise positioning. Ultrasound protection should pay attention to people with hearing and neurological disorders should not work around such equipment, high-intensity ultrasound equipment should be shielded to block ultrasound. At present, there is no exact data to prove that the ultrasonic welding machine is too much damage to the human body, but the only drawback is that the earplug must be worn when welding to prevent long-term work and affect the hearing!
