What is the principle of ultrasonic sewing machine？

The core technology of the ultrasonic wireless suturing system is the use of a disc-shaped welding head for seam welding, which cleverly converts the longitudinal vibration of the transducer into radial vibration of the disc-shaped welding head that radiates 360° outward along the diameter direction. And it is different from traditional lace machines, which generally consist of a flat tool head and a patterned roller. Since the tool head is stationary, it can easily cause fabrics such as cloth to deform and wrinkle when working, and seam welding The seamless sewing equipment uses two discs to vibrate to sew fabrics, which solves this problem very well. This not only greatly reduces the size of the vibration system itself, but also greatly reduces the installation size. The whole machine is beautiful, the volume is reduced, and the weight is also greatly reduced.

The ultrasonic sewing machine can sew most thermoplastic fabrics. Compared with ordinary needle and thread stitching, ultrasonic stitching has the characteristics of no need for needle threads, high stitching strength, good sealing, and fast stitching speed. In addition, the ultrasonic seamless stitching system has completely solved the problem of the inconsistency and synchronization between the movement direction of the ultrasonic welding head and the movement direction of the fabric. It will replace ordinary sewing machines to a large extent.

Features of ultrasonic sewing machine

High stability: During ultrasonic wireless sewing, the rotation of the welding wheel and the pressure wheel is completely synchronized, there is no speed and angle difference, and it will not cause the fabric to stretch, twist or deform, and the accuracy is extremely high. Due to the hot melt effect, there is no need to use needles and threads, the product is more waterproof, lighter and easier to fold.

Welding and cutting synchronization: Ultrasonic wireless sewing equipment is not only suitable for continuous stitching, but also can cut textiles while welding and achieve automatic edge sealing.

No heat radiation: During ultrasonic stitching, the energy penetrates the material layer for welding, and there is no heat radiation. During the continuous stitching process, heat will not be transferred to the product, which is particularly beneficial for the packaging of heat-sensitive products.

Controllable welding seam: The cloth is pulled by the welding wheel and the pressing wheel and passes between them. Ultrasonic waves are used to weld the cloth. The size and embossing of the welding seam can be changed by replacing the pressing wheel, making it more flexible and convenient to use.

Ultrasonic seamless suture principle

Ultrasonic equipment converts electrical energy into high-frequency mechanical vibration. During the high-frequency vibration process, when a certain pressure is applied to the upper cutter wheel, high temperature will be generated instantly, which will instantly melt the molecules between the fabrics and press them together to achieve wireless Purpose of suturing.
