Description

Technical Field

[0001] The utility model relates to the technical field of marking machines, in particular to a marking machine with a safety protection structure. Background Art

[0002] The marking machine uses a laser beam to mark the desired mark on the surface of various materials. The effect of marking is to evaporate the surface material of the workpiece through the laser beam to expose the deeper material, thus forming exquisite patterns, trademarks and texts.

[0003] Existing marking machines use lasers for marking, and some CO2 marking machines are dangerous during the laser marking process. When the laser comes into contact with human skin, it is easy to burn the skin, which poses certain safety hazards. In addition, if the staff stares at the laser for a long time, it will also cause certain damage to the eyes. In addition, in order to facilitate its movement, some existing marking machines are equipped with universal wheels at the bottom for movement. Although the universal wheels have a self-locking function, their contact area with the ground is still small. When they are hit after self-locking, they are still prone to large deviations, affecting normal operations. In view of this, we propose a marking machine with a safety protection structure.
