This machine utilizes the principle of ultrasonic automatic welding edge banding and knife die rolling, and accurately locates the material position through electronic induction, which can accurately complete the mask point banding and welding. This machine has the advantages of precise size control and high production efficiency, which greatly improves production efficiency, reduces production costs, and makes products more standard and more stable. The fully automatic N95 mask machine is to connect a mask body machine with a diverter, and connect it through the diverter machine and the ear strap welding machine. When the machine is started, the mask body machine produces the product and then is transported to the diverter by the conveyor belt. , After the mask is transferred from the shunt machine to the earband welding machine, the earband part is welded to complete a complete mask product. The whole process realizes a fully automated production process without manual operation.
