Abstract
Laser engravers with a masking mechanism comprise a machine body, a laser-engraving mechanism inside the machine body, a working platform, and an exhauster. The laser-engraving mechanism includes a lens-cart rail that moves back and forth along a working track. The exhauster includes air outlets behind the working platform. The masking mechanism, which includes a reelable curtain-sheet, is installed above the air outlets so that while processing, the curtain-sheet is reeled out above the working platform and an air induction channel is formed to increase the working efficiency of the exhauster.
