Description

Technical Field

[0002] In industries such as packaging, printing, and electronic labels, there are increasingly high requirements for the accuracy and efficiency of pattern engraving and marking of continuous coils. Laser engraving devices can improve the engraving efficiency, make the surface of the engraved part smooth and round, quickly reduce the temperature of non-metallic materials to be engraved, reduce the deformation and internal stress of the engraved object, and can be widely used in the field of fine engraving of various non-metallic materials.

[0003] Existing roll-to-roll laser engraving devices still have some disadvantages. For example, first, when performing roll-to-roll laser engraving, since the unwinding roller and the winding roller are not convenient for disassembly and replacement, it takes a lot of time and effort to replace them, thus affecting the working efficiency of roll-to-roll laser engraving; second, when the laser engraving material is being transported, due to the different thicknesses and materials of the coils of the laser engraving material, different tension forces are required during transportation. If the tension cannot be adjusted in time, the stability and flatness of the material during the laser processing will decrease, thus affecting the laser engraving effect. For this reason, a roll-to-roll laser engraving device is designed. Summary of the Utility Model
