Cutting device for cutting composite material

A cutting device for cutting a composite material, comprising:

• a carrier module for carrying the composite material;
• a laser generating module configured to provide a laser beam and including a laser scanning writer for providing a laser source, and a laser path adjuster located on a scanning path of the laser source, wherein the laser path adjuster adjusts the scanning path of the laser beam or the carrier module carries the composite material to move, so that a plurality of cutting areas formed by projecting the laser beam onto the composite material extend along a predetermined direction;
• and
• an air blowing and suction module having a long blowing slot configured to blow air to the cutting areas, and a long suction slot configured to suction the air from the cutting areas at the same time;
• wherein the long blowing slot and the long suction slot are adjacent to each other, and a length of the long blowing slot and a length of the long suction slot are greater than a maximum distance between two of the cutting areas that are farthest apart along the predetermined direction.
