Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to an instant printing labeling machine. Background Art

[0002] An instant printing labeling machine is an automated device that prints labels (such as barcodes and QR codes) and sticks them to products. It mainly includes a unwinding mechanism, a printing mechanism, a labeling mechanism and a rewinding mechanism. When working, the label is released to the printing mechanism through the unwinding mechanism, and the waste tape (i.e., release film) is rewinded by the rewinding mechanism. After the label is printed by the printing mechanism, the labeling mechanism absorbs the label and sticks it to the product. The traditional labeling mechanism mainly includes a labeling head and a lifting device. After the labeling head absorbs the label, the lifting device drives the labeling head to move downward, so that the labeling head presses the label and sticks it to the product. Since the labeling head needs to press against the product every time a label is applied, it will cause damage to fragile and pressure-sensitive products. Utility Model Content
