Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a labeling machine for roll labels. Background Art

[0002] The labeling machine is a device that sticks rolls of self-adhesive paper labels (paper or metal foil) on PCBs, products or specified packaging. The labeling machine is an indispensable part of modern packaging, and beautifully designed labels can also help enhance the company's image and promote product sales. Originally, product labeling was done manually, with slow labeling speed and low work efficiency. At present, the types of labeling machines produced in my country are gradually increasing, and the technical level has also been greatly improved. It has shifted from the backward situation of manual and semi-automatic labeling to the pattern of automated high-speed labeling machines occupying a large market.

[0003] The Chinese utility model patent (authorization announcement number: CN209209230U name: labeling machine) includes a fixed frame, a label changing structure, a labeling sensor structure and a label pressing structure. The label changing structure includes a label discharging structure and a label changing rod. The label discharging structure includes a matching part and a label discharging part. The labeling sensor structure includes a labeling sensor and an end fixing part. The labeling sensor is fixed to the end fixing part. The label pressing structure includes a label pressing fixing part, a label pressing connecting part and a label pressing wheel. The label changing rod is rotatably installed on the fixed frame. The label pressing fixing part and the end fixing part are independently fixed to the fixed frame. The invention solves the problem of large deviation in the integrated setting of the label pressing wheel, labeling sensor and label changing driving rod in the conventional labeling machine. The label changing structure, labeling sensor structure and label pressing structure can operate independently, and the position of the label pressing wheel will not deviate from the previous one, with high precision. At the same time, the matching parts are installed on the position of the label outlet by adjusting the matching parts, so as to adjust the extension length of the label outlet and the position of the label outlet detector. However, due to the different sizes of the coils in the early and late stages (the coils on the unwinding wheel in the early stage are large, and the coils on the winding wheel in the later stage are large), the tensioning force of the coils from the unwinding wheel to the winding wheel section is different, which makes the coils on the winding wheel loose, affecting the winding effect of the waste base material after peeling.
