Ultrasonic welding generator uses high-frequency vibration wave to transmit to two object surfaces to be welded. Under pressure, the two object surfaces rub against each other to form fusion between molecular layers. Ultrasonic welding converts 50 / 60 Hz current into 15, 20, 30 or 40KHz electric energy through ultrasonic generator, and the converted high-frequency electric energy is converted into mechanical motion of the same frequency through transducer, Then, the mechanical motion is transmitted to the welding head through a set of luffing rod device that can change the amplitude. 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 by 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 produce tens of thousands of high-frequency vibration per second. This high-frequency vibration with a certain amplitude will transmit ultrasonic energy to the welding area through the upper weldment. Due to the large acoustic resistance at the interface between the two welding areas, local high temperature will be generated, but, The ultrasonic welding machine in the prior art is prone to interval during work, can not carry out continuous work, and there is no special transportation equipment, resulting in slow work efficiency. At the same time, it needs to spend manpower for operation and supervision. Therefore, we propose a continuous welding ultrasonic welding machine.
