20khz/2000W ultrasonic welding generator for mask stitching machine
The ultrasonic mask welding machine uses the high frequency vibration wave to transfer to the two surfaces of the object to be welded. Under the condition of pressure, the two surfaces of the object rub against each other to form the fusion between the molecular layers.
ome indentations can be seen everywhere on the mask, such as edge sealing, ear band and exhalation valve are all ultrasonic welded. As shown in the above figure, in the production process of respirator, we can intuitively understand the welding of full plastic nose beam, welding after folding edge, breathing valve welding, multi-layer roll welding and ear band welding, which are actually completed by ultrasonic welding process.
When the ultrasonic wave acts on the thermoplastic contact surface, it will generate tens of thousands of high-frequency vibrations per second. This kind of high-frequency vibration reaches a certain amplitude. The ultrasonic energy is transmitted to the welding area through the upper weldment. Because the acoustic resistance of the welding area, i.e. the interface between the two welds, is large, it will generate local high temperature. Due to the poor thermal conductivity of the plastic, it can not be distributed in time for a while, and gathered in the welding area, resulting in the rapid melting of the contact surfaces of the two plastics, plus a certain amount of pressure, so that they are integrated.
