It is used for full-volume feeding of automatic folding mask production line (typical models such as N95 masks). Multi-layer non-woven fabric rolls are subjected to compound roll welding. The nose line is rolled and cut and welded. Welding after fixed-length cutting, and then the body is folded in half. After ultrasonic welding and fusion, the final mask is rolled and formed. The mask produced is comfortable to wear, no pressure, and the mask has a good transition effect. It fits the human face and can be suitable for medical treatment , Electronics, mining, construction and other industries. This machine adopts PLC, touch screen control, and the main conveyor belt adopts one-way motor transmission and transmission. The control is stable and the speed is adjustable.
