20Khz 3200W ultrasonic welding transducer for high speed Non-woven sealing and cutting

Advantages and applications of ultrasonic non-woven fabric welding machine:
This product is suitable for knitting products, bed covers, Christmas ornaments, ribbons, ready-to-wear, lace and other products. It is ergonomically designed, comfortable to operate, and can be used for curves, straight-line melting and other functions, eliminating the trouble of assembling needles, wires and spools of traditional sewing machines. The equipment can operate continuously at high speed, with high production efficiency, which can improve quality and create profits.

Convert 220V, 60HZ into 15KHZ(or 20KHZ) high voltage electric energy, and convert it into mechanical energy by using vibrator.

Such mechanical vibration is transmitted to the processed material through the transmission, welding head, and USES the air pressure to produce the friction effect of the working interface.

The vibrator and transmission device are connected to the welding head in the vibrator cylinder, and the air pressure system and control circuit are used to lift and lift under the set conditions to complete the operation procedure.

For the flat nonwoven fabric cover making machine, usually it will need the 20khz ultrasonic welding set as below, horn welding size is 110*20mm. It can use to cut the nonwoven fabric cover body and seal the nonwoven fabric cover earloop at high speed.

High Power Ultrasonic Transducers with Two Parallel Stacks for Welding 

Ultrasonic welding is used across variety of industries to join together thermoplastic materials. During ultrasonic welding, high frequency mechanical vibrations and compressive pressure are applied to the plastic materials. This creates intermolecular friction within the plastic which raises the temperature high enough to reach the melting point. During high volume production in manufacturing environments, the ultrasonic welding system component which fails most often is the transducer, which is responsible for creating the vibration. The transducer converts electrical energy into mechanical energy by means of a polarized piezoelectric PZT (lead zirconate titanate) polycrystalline ceramic material using high frequency voltage. The transducer is composed of round PZT disks attached to a titanium machined body by means of a central bolt. The bolt creates compressive pre-stress which prevents any tensile stresses within the brittle crystals during vibration and ensures perfect coupling between all components. The piezoelectric PZT crystals behave according to linear coupled electrical and mechanical equations. The transducer assembly is vibrated near the parallel resonant frequency to maximize efficiency and amplitude output.
