Ultrasonic Sewing Machine With High Air Tightness

Description: The work method of Seamless sewing part is completely imitating traditional sewing machine. The biggest characteristic is the ultrasonic transmit horn work direction is same with the sewed cloth. Which will make the sewed point of the cloth are even, flat and fastness. Through...

ultrasonic sewing machine with high air tightness



The traditional sewing machine stitches two pieces of cloth together by a needle driving wire. Although there are various advantages, there is a big disadvantage. That is, in the process of needle threading, the cloth is punctured, and there is no bond between the cloth and the cloth, but they are tied together by a thin wire. This cloth is easy to be broken and the line is easy to break. For thermoplastic fabrics, hot air welding or other direct heating methods, the two pieces of cloth can be stitched together without the use of needle threads. However, the disadvantage is that the welding temperature is not easy to control and the welding speed is slow.

Ultrasonic no sewing machine can stitch the fabric made of nylon, PVC, PU, TPU and TC. The high frequency can stick the fabric instead of needle and thread when ultrasonic machine works. It is a marked feature of this type machine that welding time is shorter and there is smokeless and no irritant taster especially for plastic materials. At the same this machine can improve the quality and improve the raise the efficiency of the products.


The ultrasonic seamless sewing movement technology skillfully uses the principle of ultrasonic bending vibration to convert the length of the high-frequency ultrasonic longitudinal vibrator into the diameter of the bending vibrator. Moreover, the direction of vibration was also rotated by 90o, which converted the longitudinal vibration into the radial vibration of the disc horn, and the installation method was also changed from vertical cloth installation to parallel cloth installation. This greatly reduces the volume of the vibration system itself, and the installation size is greatly reduced, the whole machine is beautiful, the volume is reduced, and the weight is greatly reduced. Even more gratifying is that the output of the bending disc vibration system is a transverse ultrasonic vibration, and the welding head rotates around its own axis. Simply press the pressure roller against the cylindrical surface of the welding head to rotate it in synchronism with the welding head. The processed fabric is pulled by the welding head and the pressure roller and passed between them. The fabric is heated and melted under the action of ultrasonic waves, and two or more layers of fabric are bonded together to achieve the purpose of welding the cloth. It has the characteristics of fast welding speed, high precision, beautiful weld seam, low energy consumption and simple operation. The purpose of stitching can be achieved.


Usually used in clothing industry is the ultrasonic lace machine, which is mainly used in cutting and welding cloth. Owing to its transmit horn is a plane, so it only can turn its own geometric center and cant turn the same direction with the cloth. Which make the sewed point of the cloth is unevenness. The transmit horn of Seamless sewing part is a circumference horn, and can turn around. For the cloth, it is jointing with the cloth and working at the same time. The ultrasonic seamless sewing part advance ultrasonic lace machine and its market prospects are very bright.

Main advantages:
