The ultrasonic ear band spot welding machine uses the principle of ultrasonic work to act on the non-woven fabric material to generate tens of thousands of high-frequency vibrations per second to achieve a certain amplitude of high-frequency vibration, resulting in local high temperature, and due to the poor thermal conductivity of non-woven fabrics , The temperature cannot be released in time for a while, and it gathers in the welding area, causing the contact surface of the earband and the mask to melt rapidly. After a certain amount of pressure is applied, they merge into one. When the ultrasound stops, let the pressure continue for a few seconds to solidify and form a solid molecular chain to achieve the purpose of welding, and the strength is close to that of the raw material.
