[0020] Working Principle: In mask production, the raw materials need to be cut. The fabric is laid onto one end of a conveyor belt. The motor, through the action of the first and second drive shafts, causes the conveyor belt to transport the raw materials. A limit rod above the conveyor belt ensures stable transport of the raw materials. Once the raw materials reach the cutting blade, the first and second rotary handwheels are rotated according to the mask size requirements. This rotates the first and second ball screws, causing them to move and move the cutting blade, which is fixedly connected to the ball screw bearing. The first and second ball screws have scales that allow for precise adjustment of the distance between the first and second cutting blades. Two hydraulic cylinders move two mounting blocks downwards along the inner wall of the operating frame, allowing the cutting blade to cut the mask fabric. With the transport action of the conveyor belt, the cutting blade can stably cut the mask raw materials.

[0025] 3. By setting a limiting rod above the conveyor belt, the raw material is limited, thereby keeping the raw material stable during the cutting process and achieving stable transmission of the raw material.

[0026] 4. Through the cooperation of the transport unit and the shearing unit, the transport unit moves the raw material back and forth, while the shearing unit moves up and down via a hydraulic cylinder and left and right via a ball screw. This enables stable shearing of the mask raw material and allows for flexible adjustment based on the size of the raw material. Attached Figure Description
