• Industrial Fabric Mask Welder Ultrasonic Piezoelectric Sensor And 20Khz Tool Head Mold Ultrasonic transducer also is referred to as ultrasonic vibrator, and the entire after connecting the transducer and horn is called vibrator It is a tool that realizes the mutual conversion between electricity and mechanical energy (acoustic vibration) via the piezoelectric impact of piezoelectric ceramics, and is amplified by the entrance and rear radiation disguise blocks that tournament the acoustic impedance [1] Since the horn is a passive device, it does not produce vibration itself, but transmits the input vibration after replacing the amplitude, polishing off the impedance transformation Ultrasonic transducers can produce steady vibration below the excitation of electric field, but the amplitude is usually about 10μm Such amplitude isn't enough to immediately total the welding and processing procedures Therefore, after the transducer is hooked up to a reasonably designed horn, the amplitude of the ultrasonic wave would be replaced in a wide variety As long because the material strength is sufficient, the amplitude can exceed 100 μm Ultrasonic transducer composition: 1 Middle piezoelectric ceramic detail 2 Front and rear metallic cover three Prestressed screw 4 Electrode sheet 5 Insulating tube This variety of sandwich transducer generates steady ultrasonic waves when the load changes, which is a comparatively basic and leading strategy to obtain an influence ultrasonic power source According to diversified designs, the key types of ultrasonic transducers are: 1 Column kind 2 Inverted horn type three Steel back cover form 4 Intermediate aluminum sheet form The ultrasonic transducer conducts ultrasonic waves to the plastic processing components during the welding head, so that the two plastic joints are subjected to ultrasonic waves to provide violent friction, and the friction warmth melts the plastic joints to complete the gluing This know-how has the benefits of immediate pace and firm welding seams, and extra importantly, it can 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 as the welding head is changed, one machine can be utilized for multiple functions Our company makes a speciality of the production of ultrasonic welding transducers This product has excessive performance, long life, and nice welding impact The ultrasonic utilized in plastic processing, the prevailing working frequencies are 15KHZ, 18KHZ, 20KHZ, 40KHZ The precept is to use the height function of the longitudinal wave to transmit the amplitude to the distance of the plastic part Under pressure, the 2 plastics The molecules in the touch elements of the elements or other parts and the plastic components collide with each other to melt, in order that the plastic in the contact role is fused, and the processing purpose is done Ultrasonic welding transducer for the ultrasonic processing of thermoplastic glue makes use of the high-frequency friction between the working joints to rapidly generate warmth between molecules When the heat is sufficient to soften the work, the ultrasonic vibration is stopped At this time, the operating joint The noodles are melted and solidified to finish the processing process The frequencies usually used for plastic processing are 20KHZ and 15KHZ, and their frequencies are outdoors of human hearing, in order that they are referred to as ultrasonic waves Ultrasonic welding machines should be utilized in the electronics industry, stationery industry, transportation equipment, toys, cosmetics, motors and other materials resembling 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 eleven PLS-6015-4C-Tr M16*1 60 eight 15 15 19500-20000 4200 11 PLS-6015-4C-Qu M16*1 38 12 15 15 22500-23000 27500-28000 3200 11 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 eight 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 8 PLS-3828-4C-Si BS3/8 38 4 28 15 8000-8500 a thousand five PLS-3035-4C-Si M8 30 4 35 15 5200-5600 800 four PLS-3040-4C-Si M10*1 30 four 40 15 5200-5600 800 2
