Introduction of labeling machine
Labeling machine (Labeller) is a device for sticking 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.
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 automatic high-speed labeling machines occupying the vast market.
The product type is divided into linear labeling machine and rotary labeling machine.
The main categories are: automatic vertical round bottle labeling machine, automatic horizontal round bottle labeling machine, automatic corner labeling machine, automatic wine labeling machine, flat labeling machine, automatic flat assembly line labeling head , Upper and lower self-adhesive labeling machine, double-sided pneumatic labeling machine, single-sided labeling machine, semi-automatic flat labeling machine, semi-automatic round bottle labeling machine, etc.
At the beginning of the working process, the box is fed to the labeling machine at a constant speed on the conveyor belt. The mechanical fixing device separates the boxes by a fixed distance and pushes the boxes along the conveyor belt. The mechanical system of the labeling machine includes a driving wheel, a labeling wheel, and a reel. The driving wheel drags the label tape intermittently, the label tape is pulled out from the reel, and the labeling wheel will press the label tape on the box after passing through the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label tape. Because the labels are closely connected to each other on the label tape, the label tape must constantly start and stop.
The label is attached to the box when the labeling wheel moves at the same speed as the box. When the conveyor belt reaches a certain position, the label belt drive wheel will accelerate to a speed matching the conveyor belt, and after the label is applied, it will decelerate to a stop.Since the label belt may slide, there is a registration mark on it to ensure that each label is placed correctly. The registration mark is read by a sensor. During the deceleration phase of the label tape, the drive wheel will readjust its position to correct any position errors on the label tape.
