The ultrasonic system of the mask machine is composed of an ultrasonic generator (ultrasonic electric box), ultrasonic transducer, ultrasonic welding head, and flange. It is the core welding part of the mask machine. It is used for welding around the mask, nose bridge, and ear wire welding. ; One-to-one, one-to-two automatic and semi-automatic mask machines are extremely common.
Ultrasonic matching electric box for mask machine is divided into 15k 2600W continuous vibration and 20k 2000W gap vibration.
Continuous vibration is mainly used for welding of mask pieces, gap vibration is mainly used for welding of ear strap lines, generally a mask machine needs 5-6 sets of ultrasonic supporting equipment, 1-2 continuous vibration (different design requirements are not Same), 4 sets of gap vibrations are used for welding the ear wire.
