Introduction of ultrasonic wireless sewing machine

Ultrasonic wireless sewing machine core

The core technology of the ultrasonic wireless sewing system lies in the use of a disc-type welding head for roll welding. The longitudinal vibration of the transducer is cleverly converted into a 360° outward vibration of the disc-shaped welding head along the diameter direction. Radial vibration is radiated outward in the direction of the diameter. And unlike conventional lace machines, which generally consist of a flat tool head and a patterned rolled head, the machine is not designed to be used in the same way as a conventional lace machine. The tool head is stationary and does not move, which can easily cause fabric deformation and wrinkling when working. Because the tool head is stationary, it can easily cause deformation and wrinkling of the fabric. The roll-welded seamless sewing machine, which consists of two discs vibrating to sew the fabric, solves this problem very well. This greatly reduces the size of the vibrating system itself. This greatly reduces the size of the vibrating system itself, and the installation size is greatly reduced, resulting in a beautiful machine with reduced volume and weight. The whole machine is beautiful, the size is reduced, and the weight is also greatly reduced.

The ultrasonic seamless sewing system can sew most thermoplastic fabrics. The ultrasonic sewing system can sew most thermoplastic fabrics without needles and threads, with high seam strength, good sealing and fast sewing speed. The ultrasonic seamless sewing system also completely solves the problem that the movement direction of the ultrasonic welding head is not consistent with the movement direction of the fabric. The ultrasonic seamless sewing system also solves the problem of inconsistent and unsynchronized movement of the ultrasonic welding head and the fabric, and will replace the common sewing machine to a large extent.

Conventional Sewing Machines

Traditional sewing machines sew two pieces of fabric together by driving the thread through the needle. During the process of threading the needle, not only is the fabric punctured, but there is no bond between the fabric and the cloth. This way the cloth is easily pulled and the thread is easily broken. Thermoplastic fabric can be sewn together by hot air welding, and there is no need for needle and thread, but the welding temperature is not easy to control and the welding speed is slow.

Ultrasonic wireless stitching features

High stability The rotation of welding wheel and pressing wheel are completely synchronized during ultrasonic wireless stitching, there is no speed and angle difference, which will not cause stretching, twisting or deformation of the fabric, and the precision is extremely high. Due to the heat fusion effect, there is no need to use stitches, and the product is more waterproof, lighter in quality and easier to fold.

Simultaneous welding and cutting Ultrasonic wireless sewing equipment is not only suitable for continuous sewing, but also for cutting textiles while welding and for automatic edge sealing.

No heat radiation The ultrasonic stitching energy penetrates the material layers for welding without heat radiation, and heat is not transferred to the product during continuous stitching, which is especially beneficial for packaging of heat-sensitive products.

Weld seam control The fabric is welded using ultrasound by passing between the weld wheel and the press wheel, and the size of the weld seam and embossing can be changed by changing the press wheel, making it more flexible and convenient to use.

All thermoplastic (heated and softened) fabrics, special tapes, and films can be welded with ultrasonic wireless seaming equipment, and the rollers are made of hardened steel for extended service life.

Principle of ultrasonic seamless stitching

Ultrasonic equipment is a kind of equipment that converts electrical energy into high-frequency mechanical vibration. In the process of high-frequency vibration, a certain pressure is given to the upper knife wheel, which instantly generates high temperature, melts the molecules between the fabrics instantly and presses them together to achieve the purpose of wireless stitching.

The basic composition of the equipment: ultrasonic vibrating parts + ultrasonic driving power. Ultrasonic seamless stitching principle Ultrasonic wireless stitching system is a combination of 35k ultrasonic transducer, variable amplitude rod (fixed role), disc type welding head and matching special generator. The ultrasonic generator converts the utility power into 35k high-frequency, high-voltage alternating current and supplies it to the ultrasonic transducer. The ultrasonic transducer converts the electrical energy into mechanical energy (ultrasonic wave), and the transducer generates amplitude during the longitudinal telescopic movement, which is then transmitted to the disc-shaped welding head through the amplitude rod, and the disc-shaped welding head converts the longitudinal vibration into radial vibration. This results in the welding of the disc-type welding head. With the frame, pressure wheel and auxiliary structural and control parts, it is a perfect ultrasonic.
