1 Working principle
The digital ultrasonic generator can convert low-frequency alternating current into high-frequency alternating current, and then convert electric energy into mechanical energy of high frequency vibration via the transducer. The welding head can generate tens of thousands of high-frequency vibrations per second when applied to the contact surface of thermoplastics. Through the upper weldment, the high-frequency vibrations transmit the ultrasonic energy to the welding zone, where the upper and lower weldments will generate locally high temperature through mutual friction. After the ultrasonic action, the pressure lasts for a few seconds, making the weldments solidify and set, and form strong molecular chains to achieve welding.
2 Product advantages
The ultrasonic welding system for N-series respirators has three major features: intelligence, environmental protection and high efficiency. The system can search anrJ track frequency automatically with no need of manual regulation. So it can match different product types intelligently. Additionally, the system needs no help of solvents, adhesives, or other aids, thus being capable of realize environment-friendly, pollution-free and safo production. Last but not the least, the system can replace manual welding, improve efficiency and reduce cost.
3 Applications
The ultrasonic welding system is mainly used in the fields of masks, medical protective› clothing, diapers, non-woven bags, non-woven clothing stitching, trademark slitting an‹l nylon band cutting, etc.
