Ultrasonic welding has been widely used in sanitary product production lines, such as diapers and other related products. Many fabrics, films, non-woven fabrics and paper products such as feminine products, medical masks, wipes, vacuum bags, filter cloths, etc. will use ultrasonic welding equipment .
Ultrasonic technology is powerful and has a wide range of applications. It can perform operations such as lamination, embossing, punching, cutting, and splicing. Therefore, ultrasonic welding can not only provide low-cost bonding, but also perform other operations, which improves the utilization of equipment.
The frequency range of ultrasound is 20 kHz to 1 GHz, which is inaudible to the human ear. The frequencies usually used in ultrasonic welding are 20, 30 and 35 kHz.

How does the ultrasound system produce high frequency vibration:
The ultrasonic generator converts the line voltage into a high voltage/high frequency signal and sends it to a converter. In the converter, the piezoelectric crystal is sandwiched between two pieces of titanium metal to vibrate at the frequency of the electrical signal, thereby generating very fast mechanical vibrations with a frequency of 20,000 Hz per second and an amplitude of 18 μm.

Standard ultrasonic welding machine Non-woven standard mask machine, 20KHZ1200W-2000W, 15KHZ2600W-4200W ultrasonic welding machine Non-woven welding, plastic welding, welding, PVC leather spot welding, ribbon cutting, heat sealing and other multi-functional welding equipment, outer ear tape The mask machine fuses the elastic bands on both sides of the mask body in an ultrasonic manner to complete the finished earband mask. Only one operator needs to place the mask body on the conveyor belt fixture, and the rest of the subsequent actions until the finished product is completed The machine operates automatically, and the output of this machine is higher than that of ordinary earband machines.
Plane mask machine, automatic mask spot welding machine, ultrasonic mask machine, plane mask spot welder, disposable mask machine, non-woven mask machine, ear band mask machine, N95 mask machine, FFP2 mask machine and other mechanical equipment are required It is equipped with an ultrasonic generator. This supporting equipment is aliased as an electric box and an ultrasonic control box.
The main functions of the ultrasonic generator:
Used for welding and welding of non-woven masks, welding of front-end breathing valves of cup-shaped masks, welding of nose bridge line of cup-shaped masks, spot welding of ultrasonic ear bands, cup-shaped mask ears.
