What is the ultrasonic lace machine?

High-frequency oscillation is used to transmit sound waves from the welding head to the welding surface of the workpiece, which instantly causes friction between the molecules of the workpiece and reaches the melting point of the plastic, thereby completing the rapid dissolution and welding of solid materials.
The traditional stitching step is abandoned and replaced by ultrasonic welding, making the operation simpler.

What is the Ultrasonic radial sewing machine?

Its core technology lies in the use of a disc-shaped welding head for seam welding, which cleverly converts the longitudinal vibration of the transducer into the radial vibration of the disc-shaped welding head that radiates 360° outward in the diameter direction.
The rotation of the welding roller and the pressure roller is completely synchronized, there is no difference in speed and angle, it will not cause the fabric to stretch or deform, and the accuracy is extremely high.

The bottom of the ultrasonic lace machine is an ultrasonic vibration plane, and the upper part is a steel sealing and cutting wheel. The wheel is often printed with patterns to make the welding surface beautiful. The cloth passes between the two, and through the ultrasonic vibration plane, the upper steel sealing and cutting wheel only needs to exert a small amount of pressure on the cloth to cut and weld the thermoplastic material. The vibration part of the ultrasonic sewing machine core is a circular vibrating disk. The cloth passes between the upper and lower disks, and both disks rotate at a certain speed. This can avoid wrinkles and out-of-synchronization problems caused by welding caused by one rotation of the lace machine.

The core technology of the ultrasonic seamless stitching system is the use of a disc-shaped welding head for seam welding, which cleverly converts the longitudinal vibration of the transducer into radial vibrations that the disc-shaped welding head radiates 360° outward in 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 fabrics 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.

Advantages of sewing machine core

◆High stability: During ultrasonic seamless sewing, the rotations of the welding roller and the pressure roller are completely synchronized, there is no difference in speed and angle, and the fabric will not be stretched or deformed, and the accuracy is extremely high. Due to the hot-melt effect, no needles and threads are needed, the product is more water-resistant, lighter in weight, and easier to fold.

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

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

◆Controllable welding: the welding roller and pressure roller pull the fabric, and ultrasonic welding the fabric. Replacing the pressure roller can change the size and embossing of the weld, making it more flexible and convenient to use.

◆Wide range of uses: All thermoplastic (softened after heating) fabrics, special tapes, and films can be welded using ultrasonic seamless sewing equipment. The rollers are made of quenched steel to extend their service life.
