When the laser cutting machine operates, the position of the movable plate 11 is adjusted through the supporting mechanism and the moving device 3, so that the cutting processing position of the laser head 5 on a workpiece on the base 1 is adjusted, the isolation cover 4 is abutted against the surface of the workpiece, the gasified metal dust particles generated by processing are prevented from diffusing to the outside to influence the surrounding air environment, meanwhile, the spray head 6 is aligned to the processing position of the workpiece through the direction adjusting unit, the air pump 8 sucks air through the air suction cover 9 to drive the metal dust particles to enter the processing box 13 through the air delivery pipe 10, the metal dust particles are sprayed out from the spray head 6 through the spray pipe 7 after being filtered by the filter screen 15, the heat of the workpiece is absorbed through the flowing of the air, the temperature reduction and the heat dissipation are carried out on the workpiece, the processing precision is ensured, after the cutting is finished, the workpiece is taken away, then the supporting mechanism drives the top plate 2 to move downwards, transfer simultaneously to 6 directions alignment laser head 5 of unit adjustment shower nozzle, air pump 8 is through the moisture of pumping out cover 9 extraction cage 4, carry to handling in the case 13 through the gas-supply pipe 10, carry out dehumidification drying to the air through drying unit, then heat the air by the electric heat net 16 of circular telegram, make shower nozzle 6 spray hot-air to laser head 5, dehumidify laser head 5, and make and be full of dry hot-air in the cage 4, guarantee the inside drying cabinet of cage 4, prevent that laser head 5 from receiving the moisture corruption and influencing its result of use and life, and then improved the practicality of equipment.

Compared with the prior art, this laser cutting machine with dehumidification function seals the processing position of work piece through processing agency, prevent the outside of the metal dust particle diffusion of gasification, and utilize shower nozzle 6 to spray the air to the processing position and carry out the heat absorption cooling, improve the machining precision, moreover, after the operation finishes, utilize cage 4 to keep apart laser head 5, the cooperation is transferred to the unit, air pump 8 and drying unit spray hot-air to laser head 5 and are dehumidified, make laser head 5 be in confined dry environment, avoid receiving the humid air effect to influence its use, thereby the practicality of this equipment has been improved.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
