Description

Technical Field

[0001] The invention relates to the technical field of labeling of printing and packaging, and in particular to an automatic labeling machine. Background Art

[0002] Labeling is a packaging process that pastes self-adhesive paper or metal foil labels on products or specified packaging. Labeling products not only allows users to have a general understanding of the product in terms of appearance, but also allows users to quickly obtain information such as product use from the label text. Good labels can also allow users to remember a certain product. Automatic labeling machines are equipment that can paste rolled paper or metal foil labels on specified packaging containers or products. The back of the label has its own adhesive and is regularly arranged on the glossy backing paper. The peeling mechanism on the labeling machine can automatically peel it off. Labeling can complete various operations such as flat pasting, single-sided or multi-sided pasting of packaging, cylindrical pasting, partial or full coverage of cylindrical pasting, concave and corner pasting, etc. It is an important printing and packaging machinery and equipment.
