Pzt 8 Ceramic Ring Ultrasound Emitter Piezoelectric Transducer For Fabric Bag Welding System

Pzt 8 Ceramic Ring Ultrasound Emitter Piezoelectric Transducer For Fabric Bag Welding System Ultrasonic transducer is also called ultrasonic vibrator, and the whole after connecting the transducer and horn is called vibrator. It is a device that realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and is amplified by the front and rear radiation cover blocks that match the acoustic impedance. [1] Since the horn is a passive device, it does not produce vibration itself, but transmits the input vibration after changing the amplitude, completing the impedance transformation. Ultrasonic transducers can produce regular vibration under the excitation of electric field, but the amplitude is generally about 10μm. Such amplitude is not enough to directly complete the welding and processing procedures. Therefore, after the transducer is connected to a reasonably designed horn, the amplitude of the ultrasonic wave can be changed in a large range. As long as the material strength is sufficient, the amplitude can exceed 100 μm. Ultrasonic transducer composition: 1. Middle piezoelectric ceramic element 2. Front and rear metal cover 3. Prestressed screw 4. Electrode sheet 5. Insulating tube. This kind of sandwich transducer generates stable ultrasonic waves when the load changes, which is a relatively basic and main method to obtain a power ultrasonic drive source. According to different designs, the main forms of ultrasonic transducers are: 1. Column type 2. Inverted horn type 3 Steel back cover type 4. Intermediate aluminum sheet type The ultrasonic transducer conducts ultrasonic waves to the plastic processing parts through the welding head, so that the two plastic joints are subjected to ultrasonic waves to produce violent friction, and the friction heat melts the plastic joints to complete the gluing. This technology has the advantages of fast speed and firm welding seams, and more importantly, it can automate the production and processing of plastic products. Ultrasonic plastic welding machine can perform plastic welding, embedding, forming, riveting, spot welding, cutting, sewing and other operations. As long as the welding head is changed, one machine can be used for multiple applications. Our company specializes in the production of ultrasonic welding transducers. This product has high performance, long life, and good welding effect. The ultrasonic used in plastic processing, the existing working frequencies are 15KHZ, 18KHZ, 20KHZ, 40KHZ. The principle is to use the peak position of the longitudinal wave to transmit the amplitude to the gap of the plastic part. Under pressure, the two plastics The molecules in the contact parts of the parts or other parts and the plastic parts collide with each other to melt, so that the plastic in the contact position is fused, and the processing purpose is achieved. Ultrasonic welding transducer for the ultrasonic processing of thermoplastic glue uses the high-frequency friction between the working joints to rapidly generate heat between molecules. When the heat is enough to melt the work, the ultrasonic vibration is stopped. At this time, the working joint The noodles are melted and solidified to complete the processing procedure. The frequencies usually used for plastic processing are 20KHZ and 15KHZ, and their frequencies are outside 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 materials such as PP, PE, ABS, and acrylic. （ External sizes ） （ Electeomachanical characteristic ） Sp ecification 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*1.0 60 4 15 15 9500-10000 12000-12500 2200 11 PLS-6015-4C-Tr M16*1.0 60 8 15 15 19500-20000 4200 11 PLS-6015-4C-Qu M16*1.0 38 12 15 15 22500-23000 27500-28000 3200 11 PLS-6015-6C-Si M16*1.0 60 6 15 15 18500-20500 2600 11 PLS-5020-4C-Si BS3/8 50 4 20 15 11500-12000 13500-14000 1500 8 PLS-5020-4C-Si BS3/8 50 4 20 15 19000-21000 2000 8 PLS-5020-4C-Tr M16*1.0 50 6 20 15 23000-24000 3200 8 PLS-5020-4C-Tr M16*1.0 38 6 20 15 17500-18000 3200 8 PLS-3828-4C-Si BS3/8 38 4 28 15 8000-8500 1000 5 PLS-3035-4C-Si M8.1.25 30 4 35 15 5200-5600 800 4 PLS-3040-4C-Si M10*1.5 30 4 40 15 5200-5600 800 2
