The core technology of the ultrasonic wireless suture system is to use the disc-shaped welding head for seam welding, which skillfully converts the longitudinal vibration of the transducer into the radial vibration of the disc-shaped welding head radiating outward 360° 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 a pattern. Since the tool head is stationary, it is easy to cause deformation and wrinkling of fabrics such as cloth during work, while roll welding Type seamless sewing equipment uses two discs to vibrate to sew fabrics, which solves this problem well. 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.
Ultrasonic seamless suture system can sew most thermoplastic fabrics. Compared with ordinary needle and thread suture, ultrasonic suture has the characteristics of no need for needle and thread, high suture strength, good sealing performance, and fast suture speed. And the ultrasonic seamless sewing system also completely solves the problem that the movement direction of the ultrasonic welding head is inconsistent with the movement direction of the cloth, and the problem of asynchrony will replace ordinary sewing machines to a large extent.
Traditional sewing machine
The traditional sewing machine sews two pieces of cloth together by driving the thread through the needle. In the process of threading the needle, not only the cloth is punctured but also there is no combination between the cloth and the cloth, but they are tied together by a thin thread. In this way, the cloth is easy to be pulled and the thread is easy to break. Thermoplastic cloth can be used to sew two pieces of cloth together by hot air welding, and needles and threads are not required, but the welding temperature is difficult to control and the welding speed is slow.
Features of Ultrasonic Wireless Suture
1.High stability The rotation of the welding wheel and the pressure wheel is completely synchronized during ultrasonic wireless sewing, there is no difference in speed and angle, and it will not cause stretching, twisting or deformation of the fabric, and the precision is extremely high. Due to the heat-melt effect, there is no need to use needles and threads, and the product is waterproof, lighter and easier to fold.
2.Welding and Cutting Simultaneous Ultrasonic wireless sewing equipment is not only suitable for continuous sewing, but also can cut textiles while welding, and realize automatic edge banding.
3.No heat radiation The energy penetrates the material layer for welding during ultrasonic seaming. There is no heat radiation. During the continuous seaming process, the heat will not be transferred to the product, which is especially beneficial for the packaging of heat-sensitive products.
4.Controllable welding seam The cloth is pulled by the welding wheel and the pressure wheel, and passes between them, and the cloth is welded by ultrasonic waves. The size of the weld seam and embossing can be changed by replacing the pressure wheel, which is more flexible and convenient to use.
5.Wide range of applications All thermoplastic (soften after heating) cloths, special tapes, films can be welded with ultrasonic wireless seaming equipment, and the rollers are made of hardened steel to prolong the service life.
Garment Industry
For garment manufacturers, ultrasonic sewing machines are extremely fast, clean and economical. Ultrasound can be used on a wide variety of man-made fabrics and plastics, as well as natural fabrics with a minimum content of at least 60% thermoplastic. Ultrasonic seamless seaming technology provides beautiful smooth seams to lightweight underwear and activewear fabrics, and is also great for attaching with Velcro and polyester straps. The fabric seams lie completely flat against the body with adhesive strips that are 4 times stronger than sewn seams.
Medical industry
Ultrasonic sewing machines can produce commonly used garments including protective clothing, disposable hospital surgical gowns, shoe covers, masks, baby warm clothes, filters, bags, curtains, sails and mesh stitching, etc. Ultrasonic seams are beneficial in the manufacture of these items because sealed edges and seams without seam holes are impermeable to chemicals, liquids, blood-borne pathogens, or other particles.
Outdoor industry
Ultrasonic stitching is also used to make outdoor items such as sails and parachutes because it is airtight, creating strong seams and reducing the formation of holes. This technology is widely used in clothing for skiing, cycling, sailing, mountaineering, paddle sports, hiking and other sports, waterproof backpacks, outdoor tentsand so on.
