Principle of labeling machine

Release date:2020/05/07

Working principle of labeling machine:
The beginning of the working process is that the boxes are fed to the labeling machine at a constant speed on the conveyor belt. The mechanical fixing device separates the boxes a fixed distance and pushes the boxes forward in the direction of the conveyor belt. The mechanical system of the labeling machine includes a driving wheel, a labeling wheel, and a reel. The drive wheel intermittently drags the label tape to move, the label tape is pulled out from the reel, and at the same time, the label roller will press the label tape on the box 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 continuously start and stop.
The label is attached to the box when the labeling wheel and the box move at the same speed. When the conveyor belt reaches a certain position, the label drive wheel will accelerate to match the speed of the conveyor belt, after labeling, and then slow down to stop.
Since the label may slip, it has 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 the position to correct any position error on the label tape.
