[0034] Specifically, the use of the cleaning device can ensure that the engraved product surface is smooth and free of dust pollution, thereby ensuring product quality; the cleaning device reduces dust emission, which is conducive to environmental protection and also reduces the increase of energy consumption caused by dust blockage; the suction cleaning mechanism 3 can timely remove dust and debris around the engraving cutter during the engraving process, prevent these impurities from accumulating on the engraving cutter, reduce blade wear, and prolong the service life of the engraving cutter.
