Description

Technical Field

[0001] This utility model relates to the field of gift box processing, and in particular to a laser engraving device for paper shell materials. Background Technology

[0002] Gift boxes are commonly used for packaging goods or gifts; nowadays, many products use gift box packaging.

[0003] To enhance the aesthetics of gift boxes, patterns are typically applied to their outer walls. These patterns can be created using various methods: inkjet printing followed by lamination; hot stamping to transfer patterns from foil onto cardboard; or laser engraving to burn away material from the cardboard to reveal the pattern. Laser engraving offers advantages such as creating three-dimensional patterns and eliminating the need for a protective lamination layer.

[0004] Currently, existing laser engraving equipment encounters problems when laser engraving cardboard materials. The cardboard itself may be warped or uneven due to creases, causing changes in the focal length during engraving. Therefore, it is necessary to improve this structure to overcome these defects.
