The principle of ultrasonic mask machine welding mainly uses ultrasonic technology to transmit ultrasonic energy to the welding zone through the upper welding piece, because the welding zone is the junction of two weldings.

Ultrasonic welding method for automatic inner ear mask machine. When the protective mask is moved to the production and processing part, the ultrasonic wave is automatically created, and the micro-vibration and high-frequency vibration are generated in the ear. The price of the cup-type mask machine is instantaneous. It is converted into heat and melts the raw materials required for production and processing, and finally the ear band is stuck or embedded in the protective mask itself. It is the final production and processing process for the manufacture of inner ear protective masks. The protective mask itself is placed in the protective mask plate piece by piece, and the posture is afterwards to the finished product for automatic and practical operation by the machine and equipment.

What is ultrasonic transducer

Ultrasonic transducer: A device that can convert high-frequency electrical energy into mechanical energy. Generally there are magnetostrictive and piezoelectric ceramic types. The power is output to the ultrasonic generator and then to the ultrasonic welding transducer. Generally, the ultrasonic can be generated through the ultrasonic derivation device.
The composition of an ultrasonic welding transducer includes a housing, a matching layer, that is, a sound window, a piezoelectric ceramic disc transducer, a backing, and a lead-out cable, which is characterized in that it also includes an array receiver, which consists of a lead-out cable, a transducer, Metal ring and rubber washer.
The principle and function of ultrasonic transducers: Ultrasonic transducers are piezoelectric ceramics that resonate at ultrasonic frequencies. The piezoelectric effect of materials converts electrical signals into mechanical vibrations. Ultrasonic transducers are energy conversion devices. Its function is to convert the input power into mechanical power (that is, ultrasonic waves) and then transfer it out. It consumes a small part of power by itself.
Types of ultrasonic transducers: They can be divided into piezoelectric transducers, sandwich transducers, cylindrical transducers, inverted horn transducers, and so on.
