Application of Ultrasonic welding in face mask machine
The principle of the multi-layer fusion of non-woven chemical fiber fabrics with ultrasonic wave in work is that the high-frequency friction between the contact surfaces is used to make the heat between the molecules rapidly generated under certain pressure, can Be more than both textile or fabric or PVC film, such as welding together. Usually used for non-woven welding processing frequency of 20 Khz and 15 Khz. The welding head makes tooth-like, net-like and strip-like patterns on the surface of the fused product, and causes the multi-layer cloth to fuse together.
Product advantage
1, high performance: High Mechanical Q value, electro-acoustic conversion efficiency up to more than 90% . 2. Large amplitude: the vibration velocity of the vibrator is high, and the amplitude is increased by more than 50% compared with the magnetostrictive transducer. 3, heat resistance: The use of high-quality military materials, heat resistance, low resonance impedance, small heat. 4, strong structure: Using High Quality Standard Steel No. Bolt fastening, high reliability. 5, electrical parameters: unique production process, digital equipment processing and assembly, high parameter performance, good consistency. 6, automatic frequency tracing: suitable for various sizes of welding die and different design die; 7, System Protection Monitoring: BUILT-IN HIGH-PERFORMANCE MCU and control system, real-time fast monitoring system work. The monitoring system will respond to: A. Excessive pressure leading to overloading; (b) excessive current in the ultrasonic generator; C. Loose welding head, transformer or transducer or other faults; D. Generator Circuit Failure; E. Cable failure between generator and transducer; F. Automatic compensation for power supply frequency instability. 8. AUTO TUNING: The ultrasonic generator automatically tracks and compensates for changes in the frequency of the welding head. When the temperature is too high, there is wear or debris on the surface of the welding head, the frequency changes will occur. Automatic Constant amplitude system: automatic compensation for different voltage fluctuations, ultrasonic amplitude can be adjusted from 50% to 100% stepless, to meet the requirements of different welding workpiece.

FAQ
Compared with other welding methods, ultrasonic welding can accept thermoplastic materials. It has many advantages, including process reliability and repeatability, lower energy use than other bonding technologies, saving materials and corresponding labor costs. What are the common problems in ultrasonic welding? What are the specific aspects?
Ultrasonic problem : abnormal heating of ultrasonic mold
When the ultrasonic mold is working, there will be a certain heating phenomenon, which is caused by the mechanical energy loss of the material itself and the heat conduction of ultrasonic objects. Whether the heating of ultrasonic mold is normal or not is judged as: when the ultrasonic mold is not loaded (i.e. not contacting the workpiece), the ultrasonic wave is continuously emitted for more than half an hour, and the temperature should not exceed 50-70 ºC. If the heat is damaged, it is proved that the ultrasonic mold has been damaged or the material is unqualified and needs to be replaced; if the mold temperature is too high, it is usually accompanied by abnormal high ultrasonic current;
