1. The surface layer, filter layer (or double filter layer), and bottom layer of three or four rolls of fabric are automatically aligned and fed, with double-sided symmetrical ultrasonic continuous edge pressing. After continuous roller edge pressing and cutting, ear band welding is carried out to improve production efficiency. After welding the ear band and edge wrapping, the number is automatically counted and stacked.

2. The production line adopts a "one to one" structure, where a mask body is transported through a conveyor system to the ear strap automatic welding, edging, and cutting processing station.

3. The earband can achieve automatic cutting and ultrasonic automatic welding.

4. The edging can achieve automatic edging, ultrasonic automatic welding, and automatic cutting of the edging tape.

5. The nose clip can achieve automatic feeding and cutting.
