Ultrasonic Fly Swatter Welder

parameter

The 15k 4200w Plastic Ultrasonic Welding Machine welding process is easy to operate, safe and reliable, and the welding speed is fast, which reduces the cost of the product and improves the economic benefit. At the same time, riveting, embedding, cutting, forming, sealing, etc. can also be used for welding, and the welding forms are diverse, which can meet the requirements of different occasions. The outstanding advantages of Ultrasonic Welding Machine just overcome the fatal shortcomings of traditional plastic adhesion, and can realize large-scale mass production of products and automatic control. With the extensive use of ultrasonic welding, more and more people need to understand the principle of  ultrasonic fly swatter welder.

Analog Ultrasonic Plastic Welder is mainly composed of main circuit, acoustic system, pneumatic pressure system, automatic control system, and mechanical parts. The acoustic system is the most important part. The acoustic system consists of a transducer, an amplitude modulator, and a welding horn.

The inverter converts the power frequency alternating current into high frequency alternating current and provides it to the transducer. The transducer converts high-frequency AC electrical energy into high-frequency vibration energy. The function of the amplitude modulator is to adjust the amplitude of vibration. The welding head transmits high-frequency vibration energy to the welding surface between the welding parts, so that the welding surface vibrates at high frequency. The basic principle of ultrasonic plastic welding is to apply a certain static pressure to the plastic parts that are joined by two welding surfaces. While maintaining a certain static pressure, high-frequency vibration energy is transferred to the welding surface. Under the action of this vibration, an instant high temperature is generated on the welding surface to form a molten layer between the welding surfaces, and then the vibration is stopped and the static pressure is maintained for a period of time to melt the layer. Solidification, so as to achieve a firm bond of the welding surface. Because the vibration frequency during welding is higher than 20KHz, this frequency is higher than the hearing range of the human ear, so it is called ultrasonic welding.

The principle of ultrasonic welding can be summarized as that, ultrasonic welding first transfers energy to the welding surface through high-frequency vibration to cause the temperature to rise, then the plastic melts, and then the plastic solidifies through a holding pressure time to complete the welding. So I said that the ultrasonic welding machine is not pressure welding, because the whole welding can not be completed without pressure, and the whole welding process cannot be completed with pressure alone.
