Ultrasonic generator for different machines need to have different frequency, power generator, whether it is welding machine plastic parts or non-woven, plastic bag machines are different options, taking into account the ultrasonic plastic welding machine is the most used Intermittent wave of the system will also increase the use of ultrasound time to work continuously for 7 * 24 uninterrupted work. Non-woven products machine self-styled bag machine is different from these two types of products are more frequently used with automatic or semi-automatic large-scale machine production speed is also different in the choice of ultrasonic generator to select the continuous wave of the system, here To introduce you to Jeddah ultrasonic generator, generator is divided into 15K, 20K, 28K these three frequency generator, 15K for ultrasonic welding machine for intermittent wave system, said the popular point is when the press a few machine button Only to trigger the generator internal circuit to produce sound waves, continuous wave is more 20K generator for automation equipment for more, but in 15K, 20K are intermittent wave with continuous wave is also used as 20K for When the ultrasonic welding machine is used with the 15K for the automation equipment.
Ultrasonic working principle:
Ultrasonic welding is through the ultrasonic generator that is the ultrasonic generator, the 50/60 Hz mains into 15,20,28 or 30 KHz of electricity. The converted high frequency electric energy is again converted into mechanical motion at the same frequency by the transducer (piezoelectric ceramic crystal), and then the mechanical movement is transmitted to the welding head (welding head or ultrasonic wave) by means of a set of horns which can change the amplitude Mold energy mold). The welding head transmits the received vibration energy to the joint of the workpiece to be welded. In the area of the joint, the vibration energy is converted into heat energy by friction, and the plastic is melted to achieve the effect of welding. Ultrasound can be used not only to weld hard thermoplastics, but also to fabricate fabrics and films. The main components of an ultrasonic welding system include ultrasonic generators, transducer horns / bristles triplets, molds and racks. Linear vibration Friction welding utilizes the frictional heat generated by the contact surfaces of the workpiece to be welded to melt the plastic. Heat at a certain pressure, a workpiece in the other surface with a certain displacement or amplitude of the reciprocating movement. Once the desired degree of welding is reached, the vibration will cease and there will still be some pressure applied to the two workpieces to cool and cure just the welded portion to form a tight fit. Track vibration friction welding is a method of using friction heat welding. In the case of track-type vibration friction welding, the upper part of the workpiece at a fixed speed orbital motion - to the direction of the circular motion. The movement can produce heat, so that the welding parts of the two plastic parts reach the melting point. Once the plastic begins to melt, the movement stops and the welded parts of the two workpieces are solidified and firmly connected together. Small clamping force will result in minimal deformation of the workpiece, the diameter of 10 inches within the workpiece can be applied with rail vibration friction welding.
Ultrasonic generator system:
