15kHz 4200W Ultrasonic Welding Transducer for N95 Face Cup Mask
Ultrasonic welding uses an ultrasonic generator to convert 50/60 Hz current into 15, 20, 30 or 40KHz electrical energy. The converted high-frequency electric energy is converted into mechanical operation of the same frequency through the transducer again.
Then the mechanical movement is transmitted to the welding head through a set of horn devices that can change the amplitude. Welding head will The received vibration energy is transferred to the joint of the workpiece to be welded, in this area, the vibration energy is passed The friction is converted into heat, which melts the plastic. Ultrasound can not only be used to weld hard thermoplastics
It can also process fabrics and films. The main components of an ultrasonic welding system include ultrasonic
Generator, transducer/horn/welding head triple group, mold and frame. Linear vibration friction welding utilization
The frictional heat generated on the contact surface of the two workpieces to be welded melts the plastic. Heat energy comes from a certain pressure Next, a workpiece moves back and forth with a certain displacement or amplitude on another surface. Once expected The degree of welding, the vibration will stop, and there will still be a certain amount of pressure applied to the two workpieces,Cool and solidify the just welded part to form a tight bond. Orbital vibration friction weldingJoining is a method of welding using frictional heat energy. During orbital vibration friction welding, the upper The workpiece performs orbital motion at a fixed speed-circular motion in all directions. Movement can produce The heat energy makes the welding part of the two plastic parts reach the melting point. Once the plastic starts to melt, the movement stops, The welded parts of the two workpieces will solidify and be firmly connected together. Small clamping force will cause the workpieceProduce deformation, workpieces with a diameter of less than 10 inches can be rubbed with orbital vibration Perform welding.
Ultrasonic welding is a technology in which an ultrasonic generator drives an ultrasonic transducer, vibrates tens of thousands of times per second to generate heat, and instantly melts and joins the plastic surface. Therefore, the quality of the ultrasonic transducer, It is an important factor that determines the function of the welding machine. The ultrasonic vibration head produced by Jingda Company has the characteristics of large output power, high conversion efficiency, low heat generation, and stable quality. It is the best component of the plastic welding machine.
Ultrasonic transducers are widely used. According to the industry, they are divided into industry, agriculture, transportation, life, medical treatment an According to the realized function, it is divided into ultrasonic processing, ultrasonic cleaning, ultrasonic detection, detection, monitoring, telemetry, remote control, etc.; according to the working environment, it is divided into liquid, gas, biological body, etc.; according to the nature, it is divided into power ultrasonic, detection ultrasonic, ultrasonic imaging, etc. .
The piezoelectric ceramic transformer uses the piezoelectric effect of the polarized piezoelectric body to achieve voltage output. The input part is driven by a sinusoidal voltage signal and vibrates through the inverse piezoelectric effect. The vibration wave is mechanically coupled to the output part through the input and output parts. The output part generates electric charge through the positive piezoelectric effect to realize the electric energy of the piezoelectric body. -Mechanical energy-two transformations of electrical energy to obtain the output voltage at the resonance frequency of the piezoelectric transformer. Compared with the electromagnetic transformer, this has the advantages of small size, light weight, high power density, high efficiency, breakdown resistance, high temperature resistance, no fear of burning, no electromagnetic interference and electromagnetic noise, and simple structure, easy production, and easy mass production. In some areas, it has become an ideal substitute for electromagnetic transformers. This type of transformer is used in switching converters, notebook computers, neon lamp drivers, etc.
