The ultrasonic welding generator uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other to form a fusion between molecular layers. Ultrasonic welding uses the ultrasonic generator to convert 50/60 Hz current into 15, 20, 30 or 40K Hz electrical energy, and the converted high-frequency electrical energy is again converted into mechanical movement of the same frequency through the transducer, Then the mechanical movement is transmitted to the welding head through a set of horn device that can change the amplitude, and the welding head transmits the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy through friction to melt the plastic. Ultrasonic wave can be used not only to weld hard thermoplastic plastics, but also to process fabrics and films. When ultrasonic wave acts on the contact surface of thermoplastic plastics, it will generate tens of thousands of high-frequency vibrations per second, which reach a certain amplitude. The ultrasonic energy is transmitted to the welding area through the upper weldment. Because the sound resistance at the interface between two welding areas is large, local high temperature will be generated. However, In the prior art, the ultrasonic welding machine is prone to occur interval in the work, cannot perform continuous work, and does not have special transportation equipment, resulting in slow work efficiency. At the same time, it requires manpower to operate and supervise. Therefore, we propose an ultrasonic welding machine that can continuously weld.
