Description

Technical Field

[0001] The utility model relates to the technical field of laser engraving, in particular to a laser engraving device. Background Art

[0002] Laser engraving machine uses laser beam to carve permanent marks on the surface of materials or inside transparent materials. Laser beam can produce two kinds of effects on materials: chemical effect and physical effect. When the material absorbs the laser light instantly, it will produce physical or chemical reaction, thus engraving marks or showing patterns or texts.

[0003] The existing suction devices are fixedly connected to the laser engraving machine. When the plate is thick or thin, it cannot absorb the smoke in time, resulting in a limited suction range. The traditional way to discharge smoke is to filter it through the filter plate and then discharge it directly. This method requires regular replacement of the filter plate. Over time, the surface of the filter plate will be covered with smoke, which not only affects the exhaust, but also makes it difficult to clean. To this end, we provide a laser engraving device to solve the above problems. Utility Model Content
