Description

Technical Field

[0001] The utility model relates to the technical field of flexible paper marking, in particular to a laser labeling machine. Background Art

[0002] 3M flexible paper labels have been widely used in the automotive parts, automobile manufacturing, instrumentation, electronic appliances and other industries. According to relevant statistics, a car uses more than 30 3M laser label papers. The laser marking process requires the use of laser etching on the paper label. It can replace the original metal nameplate and has the characteristics of anti-tampering, cost saving, flexible engraving, and no inventory.

[0003] In existing technology, the inner diameter of the flexible paper roll core shaft varies due to the varying sizes of car labels for different brands or types.
