[0002] Laser engraving machine is a kind of equipment that uses laser to engrave the materials to be engraved. It uses high-temperature laser to burn various shapes of patterns on the parts to be processed. When the laser engraving machine is in use, when its high-temperature laser comes into contact with the parts to be processed, some impurities on the parts will generate harmful gases under the action of high temperature, so it is necessary to use a dust removal and fume exhaust mechanism to deal with the gas generated by the laser engraving machine when it is in use.

A laser engraving machine 7 is fixed to the bottom end of the mounting member 5. A smoke removal mechanism 6 is arranged at the rear side of the servo cylinder 4.

[0024] A dust box 8 is fixedly installed on one side of the top of the workbench 1, a water pump 9 is fixedly installed on one side of the dust box 8, output pipes 10 are fixed at both ends of the water pump 9, a water spray head 11 is fixed at one end of the output pipe 10, a plurality of movable grooves 13 distributed in a rectangular shape are provided on the inner side of the dust box 8, a movable block 14 is movably installed on the inner wall of the movable groove 13, an extrusion spring 15 is fixed at the bottom end of the movable block 14, a screen 16 is commonly fixed at the opposite end of the movable block 14, a servo motor 19 is fixed to the outer wall of one side of the dust box 8, and a screening mechanism 20 is provided at the driving end of the servo motor 19.

[0025] The smoke removal mechanism 6 can mainly absorb the smoke generated by the laser engraving machine 7.

At the same time, the tap 63 can also rotate, thereby adjusting the direction of the tap 63, thereby further improving the smoking efficiency.

[0026] The screening mechanism 20 can mainly absorb the excess recycled debris absorbed during smoking, and at the same time, the screening mechanism 20 can screen the debris, thereby improving the efficiency of debris recycling.

[0027] Further as Figure 1 , Figure 2 As shown, it is worth explaining in detail that the smoke removal mechanism 6 includes a fan 61, which is fixedly installed on the rear side of the top of the workbench 1, and the output ends on both sides of the fan 61 are respectively fixed with a shunt pipe 62 and a delivery pipe 64, and taps 63 are fixed at both ends of the shunt pipe 62.

[0028] By starting the fan 61, the smoke and debris generated during carving can be absorbed, and at the same time, the absorbed debris can be recycled through the screening mechanism 20, thereby improving the effect of debris recovery.

[0029] Further Figure 1 , Figure 2 , Figure 3 As shown, it is worth explaining in detail that the two taps 63 are rotatably mounted on the two ends of the mounting member 5 , and the other end of the conveying pipe 64 extends to the top end of one side of the dust collecting box 8 .

[0030] The present solution has the following working process: when it is necessary to absorb the smoke generated by the engraving, the servo cylinder 4 is started again so that it can drive the mounting part 5 to move, and then the tap 63 can be driven to move, so that the tap 63 can be closer to the laser engraving machine 7, so as to improve the smoking efficiency. At the same time, during the smoking process, the debris generated by the engraving can be absorbed, and then transported to the inner wall of the dust box 8 through the conveying pipe 64, and then the debris is recovered through the screening mechanism 20, and then the servo motor 1 is started again. 9, thereby, the rotating rod 201 can be driven to rotate, and then the eccentric wheel 202 can be driven to rotate, and the movable part 204 can be driven to move through the eccentric wheel 202, and then the connecting part 18 can be driven to be subjected to force up and down, thereby the screen 16 can be driven to be subjected to force, so that the debris can be quickly screened. At the same time, the screen 16 is inclined, and a discharge pipe 17 is provided at the bottom, so that the debris on the inner wall of the discharge pipe 17 can be transported to the inner wall of the collecting box 21, so that the debris can be recovered.

[0037] The discharge pipe 17 can correspond to the collection box 21, so that the collected debris can be transported to the inner wall of the collection box 21, thereby achieving the effect of recycling.

[0038] In summary: the smoke removal mechanism 6 can mainly absorb the smoke generated by the laser engraving machine 7, and the tap 63 can also move up and down with the mounting part 5 and the laser engraving machine 7, so as to further improve the smoke removal efficiency. At the same time, the tap 63 can also rotate, thereby adjusting the direction of the tap 63, thereby further improving the smoking efficiency. By starting the water pump 9, the water source at the bottom of the dust box 8 is extracted through the output pipe 10 at one end, and then transported to the inside of the water spray head 11 through the output end on the other side, so that the extracted smoke can achieve dust reduction effect, so that the smoke can quickly fall onto the surface of the activated carbon filter 12, thereby improving the filtering effect of the smoke, and the water source can fall into the bottom of the inner wall of the dust box 8 again, and the water source can also be recycled.
