[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. As the relative position of the beam and the workpiece moves, a slit is eventually formed on the material, thereby achieving the purpose of cutting. The use of this equipment replaces manual operation and has the characteristics of high precision, fast cutting, and no restrictions on cutting patterns.

[0003] After searching, a Chinese patent with announcement number CN218341251U discloses a laser cutting machine, which includes a frame and a laser cutting head. A first linear motor is fixed to the inner top wall of the frame, a holder is fixed to the bottom end of the moving part of the first linear motor, a laser cutting head is arranged on one side of the holder, a bracket is fixed to the bottom end of the frame, two second linear motors are fixed to the top end of the bracket, the moving parts of the two second linear motors are connected to a support plate arranged below the laser cutting head, through grooves are provided on the support plate and the bracket, and two clamping members are arranged on the top end of the support plate; the clamping members include a block and a clamping plate, a hydraulic cylinder is fixed to the side wall of the block, a clamping plate is fixed to the piston rod of the hydraulic cylinder, and a protective pad is fixed to the side of the clamping plate away from the hydraulic cylinder. The laser cutting machine improves efficiency and facilitates the disassembly of the laser cutting head.

[0004] The beneficial effects in the above patent mention that "the piston rods of the two hydraulic cylinders drive the two clamping plates to move toward each other, which is convenient for clamping automobile parts. After cutting, the moving parts of the two second linear motors drive the support plates and automobile parts to move to the top of the trough body, and the piston rods of the two hydraulic cylinders drive the two clamping plates to move away from the automobile parts. The automobile parts fall into the trough body with their own weight, thereby realizing the collection of automobile parts."

This smoke and exhaust gas may contain harmful substances, which will cause long-term physical and mental health of the staff and affect the air environment. Therefore, in response to the above problems, a laser cutting machine with a smoke removal structure is proposed. Utility Model Content
