The welding principle of ultrasonic spot welding machine is to convert 50 / 60 Hz current into 15, 20, 30 or 40 kHz electric energy visit site through ultrasonic generator. The converted high-frequency electric energy is converted into the mechanical motion of the same frequency again through the transducer, and then the mechanical movement is transmitted to the welding head through a set of amplitude modulator device which can change the amplitude. The vibration energy received by the welding head is transferred to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction, and the plastic wholesale face mask is melted. After the vibration stops, the short-term pressure maintained on the workpiece makes the two weldments solidify in the form of molecular link. Generally, the welding time is less than 1 second, and the welding strength obtained is comparable to that of the body. Ultrasonic can be used not only to weld hard thermoplastic plastics, face mask for men but also to process fabrics and films. The main components of an ultrasonic welding system include ultrasonic generator, transducer / amplitude modulator / welding head, mould and frame.
Machine performance:
1. The design of the machine is compact and flexible, and the operation is simple and convenient.
2. It can be used for welding plane, inner ear belt / outer ear belt, cup type mask, duck beak type and other special-shaped masks.
3. After the mask body is made, the ear band is welded manually, kn95 mask manufacturer which is easy to operate and the contact is firm and beautiful. Skilled workers weld 10-12 pieces of ear tape per minute.
Features:
1. Ultrasonic spot welding machine adopts original transducer, stable output, high-quality component assembly, reliable performance, smart design and convenient operation. It is mainly suitable for N95 mask (cup mask, dust mask, duck beak mask, plane mask, etc.) ear band spot welding, with high production efficiency, simple operation and stable quality;
2. The double guide pillar design can solve the problem of backward tilt during welding;
3. The operation is simple, and the welding spot is firm and beautiful after welding, without damaging the material itself.
