• 15KHz 4200W High Power Ultrasonic Piezoelectric Emitter Transducer For Geo Grid Welding Machine Ultrasonic transducer also is called ultrasonic vibrator, and the entire after connecting the transducer and horn is named vibrator It is a device that realizes the mutual conversion between electricity and mechanical energy (acoustic vibration) by means of the piezoelectric impact of piezoelectric ceramics, and is amplified by way of the entrance and rear radiation disguise blocks that event the acoustic impedance Since the horn is a passive device, it does not produce vibration itself, yet transmits the input vibration after replacing the amplitude, completing the impedance transformation Ultrasonic transducers can produce regular vibration under the excitation of electrical field, but the amplitude is mostly about 10μm Such amplitude isn't enough to directly total the welding and processing procedures Therefore, after the transducer is attached to a reasonably designed horn, the amplitude of the ultrasonic wave can be replaced in a wide variety As lengthy because the materials strength is sufficient, the amplitude can exceed one hundred μm Ultrasonic transducer composition: 1 Middle piezoelectric ceramic element 2 Front and rear metal hide 3 Prestressed screw 4 Electrode sheet five Insulating tube This kind of sandwich transducer generates steady ultrasonic waves when the load changes, which is a relatively basic and leading way to achieve an influence ultrasonic force supply According to varied designs, the foremost forms of ultrasonic transducers are: 1 Column form 2 Inverted horn sort 3 Steel back hide kind 4 Intermediate aluminum sheet sort The ultrasonic transducer conducts ultrasonic waves to the plastic processing parts through the welding head, in order that the two plastic joints are subjected to ultrasonic waves to produce violent friction, and the friction warmth melts the plastic joints to complete the gluing This expertise has some great benefits of immediate pace and agency welding seams, and more importantly, it is going to automate the production and processing of plastic merchandise Ultrasonic plastic welding machine can perform plastic welding, embedding, forming, riveting, spot welding, cutting, stitching and different operations As long because the welding head is changed, one mechanical device can be used for multiple purposes Our corporation focuses on the manufacturing of ultrasonic welding transducers This product has excessive performance, lengthy life, and good welding effect The ultrasonic utilized in plastic processing, the present working frequencies are 15KHZ, 18KHZ, 20KHZ, 40KHZ The principle is to use the peak role of the longitudinal wave to transmit the amplitude to the gap of the plastic section Under pressure, the two plastics The molecules in the contact elements of the parts or different parts and the plastic elements collide with one another to melt, so that the plastic within the touch role is fused, and the processing goal is finished Ultrasonic welding transducer for the ultrasonic processing of thermoplastic glue uses the high-frequency friction between the working joints to rapidly generate warmth between molecules When the warmth is adequate to soften the work, the ultrasonic vibration is stopped At this time, the operating joint The noodles are melted and solidified to complete the processing process The frequencies usually used for plastic processing are 20KHZ and 15KHZ, and their frequencies are exterior of human hearing, so they are called ultrasonic waves Ultrasonic welding machines should be used in the electronics industry, stationery industry, transportation equipment, toys, cosmetics, motors and other supplies equivalent to PP, PE, ABS, and acrylic （External sizes） （Electeomachanical characteristic） Specification Connect Screw Ceramic diameter（mm） Quantity of Ceramics（pcs） Resonance Frequency（KHZ） Resistance（Ω） Yellow Ceramic Black Ceramic Input Power Max Displacement（um） PLS-6015-4C-Si M16*1 60 four 15 15 9500-10000 12000-12500 2200 11 PLS-6015-4C-Tr M16*1 60 8 15 15 19500-20000 4200 11 PLS-6015-4C-Qu M16*1 38 12 15 15 22500-23000 27500-28000 3200 eleven PLS-6015-6C-Si M16*1 60 6 15 15 18500-20500 2600 11 PLS-5020-4C-Si BS3/8 50 four 20 15 11500-12000 13500-14000 1500 8 PLS-5020-4C-Si BS3/8 50 four 20 15 19000-21000 2000 8 PLS-5020-4C-Tr M16*1 50 6 20 15 23000-24000 3200 eight PLS-5020-4C-Tr M16*1 38 6 20 15 17500-18000 3200 eight PLS-3828-4C-Si BS3/8 38 four 28 15 8000-8500 one thousand five PLS-3035-4C-Si M8 30 4 35 15 5200-5600 800 4 PLS-3040-4C-Si M10*1 30 four forty 15 5200-5600 800 2
