The ultrasonic spot welding machine uses original transducers, with stable output, high-quality component assembly, reliable performance, smart machine design, easy operation, high production efficiency, simple operation, stable quality, etc.; the operation is simple, and the solder joints are strong and beautiful after welding. No damage to the material itself. The non-woven spot welding machine converts 50/60 Hz current into 20 kHz electrical energy through an ultrasonic generator. It is converted again into mechanical motion of the same frequency through the transducer and transmitted to the welding head through the amplitude modulator. The welding head transmits the received vibration energy to the joint of the non-woven mask to be welded. The vibration energy is converted into heat energy through friction, which melts the non-woven fabric. The non-woven fabrics on both sides are solidified into one body through molecular linking, and are perfectly combined to achieve the welding e…
