Ultrasonic Radial Sewing Movement

Ultrasonic Radial Sewing Movement

Date:Nov 27, 2019

The ultrasonic sewing movement is used for fabric stitching and cutting, and is an internationally developed technical achievement. The company closely follows the research results of foreign countries and develops ultrasonic seamless sewing movements. This is the core component of an ultrasonic seamless sewing machine (also called an ultrasonic radial sewing machine). It completely solves the inherent problem of the original ultrasonic longitudinal vibration technology, that is, the moving direction of the ultrasonic welding head is inconsistent with the moving direction of the cloth, and is not synchronized. The precision of ultrasonic cloth stitching has been greatly improved, making it possible to apply ultrasonic technology widely in the field of garment stitching. Ultrasonic seamless sewing has the characteristics of fast welding speed, high strength, beautiful weld seam, good sealing performance, low energy consumption and simple operation. It is the development direction of sewing machine.

Ultrasonic seamless sewing machines are used in a wide range of applications, and almost all thermoplastics (ie softened after heating) can be used. Moreover, compared with the ordinary needle stitching, the ultrasonic stitching does not use the needle and the thread, and the stitching strength is high and the sealing property is good. It is very likely that, to a large extent, it will replace the ordinary sewing machine. We are willing to work with the whole machine manufacturers to make our contribution to improving the sewing machine industry in China.

The seamless sewing movement consists of a 35k ultrasonic longitudinal vibration transducer, a pitch horn, a disc-shaped horn, a second horn, and a dedicated drive power supply. Its working principle is that the ultrasonic drive power source converts the mains into 35k high-frequency high-voltage AC current and sends it to the ultrasonic transducer. An ultrasonic transducer is actually equivalent to an energy conversion device that converts input electrical energy into mechanical energy, ie, ultrasonic waves. Its manifestation is that the transducer moves back and forth in the longitudinal direction. The frequency of the telescopic movement is equivalent to the frequency of the alternating current supplied by the driving power source, that is, 35k, and the displacement of the telescopic movement is about several micrometers. The function of the horn is to fix the entire ultrasonic vibration system, and the second is to amplify the output amplitude of the transducer and transmit it to the welding head. On the one hand, the welding head further amplifies the amplitude and on the other hand converts the longitudinal stretching vibration into a radial stretching vibration. As long as the machine manufacturer is equipped with a frame, a pressure roller and an auxiliary structure and control components, it is a finished ultrasonic cutting sewing machine.
