Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting, and in particular relates to laser cutting equipment capable of targeted dust removal. Background Art

[0002] Laser cutting is the process of focusing the laser emitted from a laser into a high-power density laser beam through an optical path system. The laser beam is irradiated onto the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a cut is eventually formed in the material, thereby achieving the purpose of cutting.

[0003] A Chinese patent application with publication number CN218476174U discloses a plate laser cutting device with a dust removal function, including a workbench, the workbench is connected to a plurality of evenly distributed adjustment mechanisms, the end of the workbench away from the adjustment mechanism is connected to a C-shaped frame, the C-shaped frame is slidably connected to a laser cutting assembly, the workbench is provided with a placement groove, the placement groove is connected to a plurality of evenly distributed dust collection grooves provided on the workbench, clamping mechanisms are connected to both sides of the workbench, the end of the workbench away from the C-shaped frame is connected to a dust removal mechanism, the dust removal mechanism includes a dust collecting box connected to the lower end of the workbench, one end of the dust collecting box is connected to a motor B, the output end of the motor B is connected to a rotating shaft B, the rotating shaft B is connected to a pulley B, and the pulley B is movably connected to a belt B. The utility model realizes the action of adsorbing metal debris generated during the cutting process of the metal plate, improves the cleanliness of the workbench, and improves the subsequent processing efficiency of the metal plate.

[0004] Although the metal debris generated during the cutting process of the metal sheet can be adsorbed, the cleanliness of the workbench is improved, and the subsequent processing efficiency of the metal sheet is improved, it does not have a targeted dust removal function. The installation position of the exhaust component is far away from the cutting table, which greatly disperses its suction capacity, resulting in its inability to effectively suck the smoke and dust, causing the smoke and dust to fly everywhere and pollute the surrounding environment. For this reason, we provide a laser cutting device with targeted dust removal to solve the above problems. Utility Model Content
