The ultrasonic generator converts 50 / 60 Hz current to 20 kHz. The sensor converts it into mechanical motion of the same frequency again and transmits it to the welded joint through the amplitude modulator. The vibration energy received by the welded joint is transferred to the non-woven fabric mask joint to be welded, and the vibration energy is converted into heat energy through friction to melt the non-woven fabric. The two sides of the nonwovens are solidified in the form of molecular chains to get a perfect combination, so as to achieve the welding effect. The equipment using this principle includes: mask ear band spot welding machine, non-woven cloth mask welding machine, non-woven cloth mask spot welding machine, non-woven fabric mask sewing machine, ultrasonic mask lace machine, ultrasonic mask spot welding machine, medical mask spot welding machine and automatic mask ear band welding machine.

Characteristics of ultrasonic non-woven fabric mask spot welding machine

One. Japanese original piezoelectric ceramic transducer, strong and stable output; two. Super power, can handle all kinds of hard pressed fabric, according to the thickness of fabric, power can be adjusted; three. The fuselage is designed to prevent back tilt and coaxial direct pressure, and the pressure is applied evenly to improve the spot welding accuracy. The vibrator is imported with original packaging, high conversion efficiency, high ultrasonic energy, and not easy to burn. The important electronic components of the equipment are made of high-quality original foreign brands with guaranteed quality. The die assembly adopts sliding type flower wheel bracket, the size is adjustable, and the operation is convenient; there are seven. The bottom die of Foshan hangmei aluminum products is made of high strength die steel, which can be rotated to reduce the wear between the die and the bottom surface, and has a long service life. The equipment features of mask ear band spot welding machine, non-woven fabric mask welding machine, non-woven fabric mask sewing machine, ultrasonic mask lace machine, ultrasonic mask spot welding machine, medical mask spot welding machine and automatic mask ear band welding machine are the same.

Application of ultrasonic non-woven fabric mask spot welding machine

Non woven fabric mask spot welder has the functions of welding, sewing, trimming, forming, embossing, stamping, punching, cutting, etc.; it is suitable for chemical fiber cloth, nylon cloth, knitted fabric, non-woven fabric, cotton spray, polyethylene paper, polyethylene aluminum, polyethylene cloth composite materials; it is suitable for clothing, headwear series, Christmas ornaments, bedclothes, car covers, non-woven fabrics, leather lace, pajamas, interior Foshan hangmei aluminum products have one-time investment mold, no burr and easy to change flower wheel Various styles, fast, no preheating, no temperature adjustment and so on. The application fields of mask ear band spot welding machine, non-woven fabric mask welding machine, non-woven fabric mask sewing machine, ultrasonic mask lace machine, ultrasonic mask spot welding machine, medical mask spot welding machine and automatic mask ear band welding machine are almost the same.
