The three-axis screw moving module 3 is composed of screw linear modules in three moving directions, thereby controlling the moving path of the laser cutter 4 on the X, Y and Z axes;

[0021] The belt feeding structure 10 includes synchronous wheels rotatably mounted on both ends of the U-shaped truss 9, and a conveyor belt installed between the two synchronous wheels. One end of the spline transmission shaft 12 passes through the outside of one of the synchronous wheels.
