ultrasonic plastic spot welding machine for pvc umbrella 28K
The welding principle of ultrasonic spot welding machine is to convert 50/60 Hz current into 15, 20, 30 or 40 kHz electric energy through ultrasonic generator. The converted high frequency electric energy is converted into mechanical motion of the same frequency again through the transducer, and then the mechanical motion is transmitted to the welding head through a set of amplitude modulator device which can change the amplitude. The welding head transmits the received vibration energy 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 is melted. The transient pressure maintained on the workpiece after vibration stops makes the two weldments solidify as a whole by means of molecular linkage. Generally, the welding time is less than 1 second, and the welding strength obtained is comparable to that of the body. Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films. The main components of a set of ultrasonic welding system include ultrasonic generator, transducer/amplitude modulator/welding head triple group, die and frame.
