Automatic mask ear strap ultrasonic welding machine is specially designed for mask ear strap rope spot welding, the principle is the high voltage, high frequency signal generated by the ultrasonic generator, through the energy conversion system, The signal is converted into high-frequency mechanical vibration, which is added to the plastic product workpiece, and the temperature transmitted to the interface is increased by the friction between the workpiece surface and the internal molecular parts. When the temperature reaches the melting point of the workpiece itself, the workpiece interface is rapidly changed. Melt, and then fill the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, and perfect welding is achieved.
Automatic mask ear strap ultrasonic welding machine uses ultrasonic method to fuse the outer sides of the mask body to complete the production of ear strap rope mask finished products. It has the characteristics of high welding strength, high work efficiency, simple operation, and stable quality .
