35kHz 800W Rotary Ultrasonic Sonotrode in Seamless Underwear Lace Machine

The work method of Seamless sewing part is completely imitating traditional sewing machine. The biggest characteristic is the ultrasonic transmit horn work direction is same with the sewed cloth. Which will make the sewed point of the cloth are even, flat and fastness. Through suitable design, it can reach perfect sewing effectiveness.

Ultrasonic bonding is achieved by transmitting high frequency vibration to the fabric. When synthetic materials or nonwovens pass between the corner and anvil of the ultrasonic equipment, the vibration will be directly transmitted to the fabric, thus generating heat rapidly in the fabric. The ultrasonic energy generated by the ultrasonic generator is added to the transducer to generate longitudinal mechanical vibration, which is amplified by the horn and the tool head to obtain uniform and strong ultrasonic on the plane of the tool head (also known as the welding head).
Two groups of adjustable speed motors drive the welding head and the welding roller to rotate respectively. When the roller is pressed down, it contacts with the working surface of the tool head. Under the action of ultrasonic mechanical effect (up and down vibration) and thermal effect, the fabric between the roller and the working surface of the welding head can be cut, perforated, stitched and welded..
