The core technology of the ultrasonic seamless stitching system lies in the use of a disc-shaped welding head for roll welding, cleverly converting the longitudinal vibration of the transducer into radial vibration radiating outward 360 ° along the diameter direction of the disc-shaped welding head. And unlike traditional lace machines, traditional lace machines are generally composed of flat tool heads and patterned rollers. Due to the stationary tool heads, it is easy to cause deformation and wrinkling of fabrics and other fabrics during operation. The roll welding seamless sewing equipment uses two discs to vibrate and sew fabrics, which effectively solves this problem. This not only greatly reduces the volume 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 greatly reduced.
Advantages of sewing machine movement:
1. High stability: When using ultrasonic seamless sewing, the rotation of the welding roller and the pressure roller is completely synchronized, with no difference in speed and angle, which will not cause fabric stretching or deformation, and the accuracy is extremely high. Due to the hot melt effect, needles and threads are not required, resulting in increased water resistance, lighter weight, and easier folding of the product.
2. Welding and cutting synchronization: Ultrasonic seamless sewing equipment is not only suitable for continuous sewing, but also for cutting textiles while welding, achieving automatic edge sealing.
3. No thermal radiation: During ultrasonic sewing, energy penetrates the material layer for welding without thermal radiation. During the continuous sewing process, heat is not transferred to the product, which is particularly advantageous for packaging thermal sensitive products.
4. Controllable welding: Welding rollers and pressure rollers pull the fabric, and ultrasonic welding of the fabric. Replacing the pressure roller can change the size and embossing of the weld seam, making it more flexible and convenient to use.
5. Widely applicable: All thermoplastic (softened after heating) fabrics, specialized tapes, and films can be welded using ultrasonic seamless sewing equipment, and the rollers are made of quenched steel to extend their service life.
