The ultrasonic seamless sewing system is composed of 35K ultrasonic transducer, horn (fixed function), disc welding head and special NC power supply. The ultrasonic numerical control power supply converts the commercial power into 35K high frequency and high voltage AC and supplies the ultrasonic transducer. The ultrasonic transducer converts electric energy into mechanical energy (ultrasonic). When the transducer moves longitudinally, it generates amplitude, which is then transmitted to the disc welding head through the horn. So that the disc type welding head is welded, equipped with the frame, pressure wheel and auxiliary structure and control components, it is a complete ultrasonic cutting sewing machine.
The key technology of the acoustic seamless stitching system is to use the disc type welding head for roll welding, which skillfully converts the longitudinal vibration of the transducer into the radial vibration that the disc type welding head radiates 360 ° outward along the diameter direction. And different from the traditional lace machine, the traditional lace machine is generally composed of a flat tool head and a roller with pattern. Because the tool head is stationary, it is easy to cause fabric deformation and wrinkling when working. The roll welding seamless sewing machine uses two discs to sew fabric, which 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 also greatly reduced.
High stability: the rotation of welding wheel and pressing wheel is completely synchronous during ultrasonic seamless sewing, there is no difference in speed and angle, and the cloth will not be stretched, twisted or deformed, with high precision. Due to the use of hot-melt effect, there is no need to use needle and thread, the product is more waterproof, lighter and easier to fold.
Synchronous welding and cutting: ultrasonic seamless sewing equipment is not only suitable for continuous sewing, but also can cut textiles while welding, and realize automatic edge sealing.
No thermal radiation: when ultrasonic stitching, the energy penetrates through the material layer for welding, and there is no thermal radiation. In the continuous stitching process, the heat will not be transferred to the product, which is particularly beneficial to the packaging of thermal sensitive products.
Welding seam controllable: cloth is pulled by welding wheel and pressing wheel, through which cloth is welded by ultrasonic wave. The welding seam size and embossing can be changed by changing pressing wheel, so it is more flexible and convenient to use.
Wide range of applications: all thermoplastic (softened after heating) cloth, special tape and film can be welded with ultrasonic seamless sewing equipment, and the roller is made of quenched steel to extend its service life.
