[0002] The anti-counterfeiting features and identification methods of anti-counterfeiting labels are the soul of anti-counterfeiting labels. The production process of anti-counterfeiting labels is relatively complicated. Label lamination has become particularly important in the era of information development. Lamination refers to the processing technology of laminating a transparent plastic film to the surface of a printed matter by hot pressing. Lamination can protect the printed matter and increase its gloss. Traditional label laminating devices often do not have cooling and tensioning functions, which can easily cause the labels to stick and entangle after lamination, and bubbles are easily generated during lamination, affecting product quality. A flat laminating device for anti-counterfeiting labels is now proposed, which can control the tension of the conveying mechanism, cool the label after lamination, make the lamination take shape quickly, and discharge the bubbles inside the label while transporting the label, thereby improving product quality.
