[0002] A mask is a sanitary and anti-epidemic product, generally worn on the mouth and nose to filter the air entering the mouth and nose, so as to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper and other materials. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. Masks can be divided into air filtering masks and air supply masks. At present, the medical mask shape cutting equipment includes a workbench, a cylinder and a cutting knife. The cylinder is located above the workbench, and the cutting knife is located between the workbench and the cylinder, and the cutting knife is fixedly connected to the end of the cylinder piston rod. The staff places the raw material on the workbench, drives the cutting knife down through the cylinder, and cuts the mask out of the raw material with the cutting knife, thereby completing the cutting of the mask shape.

[0003] However, the shape of the mask cut out by the cutting device is certain. With the increasingly developed society and the pursuit of high-quality life, people sometimes not only need masks to meet the protection needs of heating pipes, but also need masks to have a certain aesthetics, so masks are required to have different styles.
