Description

Smoke dust filtering device of laser coding machine Technical Field The invention relates to the technical field of coding machines, in particular to a smoke dust filtering device of a laser coding machine. Background The laser coding machine directly gasifies in the twinkling of an eye at object surface through laser and forms the mark, and laser is shone and is produced waste gas on the product surface, and waste gas drifts and can make the workman feel uncomfortable in the air, usually can be equipped with smoke and dust filtration equipment in the laser coding region. Through retrieving, application number CN202221236053. X's patent discloses a smog filter equipment and have its laser to beat a yard device, and the intake pipe stretches into to the water tank and is located the below of liquid level for smog can get into in the filtrate liquid through the intake pipe, and smog is discharged the water tank after being purified by the filtration liquid, can purify smog effectively, and smog purification's cost is lower simultaneously. However, when the air inlet pipe stretches into the shallow position of the liquid level of the water tank, waste gas is discharged into the filtrate and then contacts with the filtrate on the shallower layer, then the waste gas flows to the position above the liquid level, the time for filtering smoke dust is shorter, the smoke dust in the middle position is easy to be discharged without contacting with the filtrate when the volume of the smoke dust is larger, the smoke dust is not thoroughly filtered, the length of the filtrate entering the air inlet pipe is increased along with the fact that the air inlet pipe continues to stretch into the deeper position of the filtrate, the smoke dust needs to push out the filtrate in the air inlet pipe for a longer distance to the outside of the air inlet pipe, the waste gas can be discharged into the filtrate for filtering, part of power of the air pumping equipment is used for pushing the filtrate, and finally the power of the smoke dust pumped in the air inlet is reduced, so that the range of the smoke dust filtering effect of the air pumping equipment is reduced, and the effect of filtering the smoke dust is poor.
