1. The surface layer, filter layer, and bottom layer of the fabric are automatically aligned and fed, with double-sided symmetrical ultrasonic continuous edge pressing. After continuous roller edge pressing and cutting, they are divided into two workstations for ear band welding to improve production efficiency. After welding the ear bands, the digital stack is automatically counted.

2. The production line adopts a "one to two" structure, where one mask body is automatically transported and divided into two sets of ear strap automatic welding processing stations through a conveyor system.

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

4. The ear strap can achieve automatic cutting and ultrasonic automatic welding
