Most of the labeled products that we see in our lives are quickly labeled by automatic labeling machines. Are you curious about the working principle of the labeling machine?
Here is an introduction to the working principle of the automatic labeling machine:
1. At the beginning, 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 rotary automatic labeling machine, a labeling wheel, and a reel.
2. The driving wheel intermittently drags the label tape to move, 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.
3. 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 belt drive wheel will accelerate to a speed matching the conveyor belt, and after the label is attached, it will decelerate to a stop.
4. Since the label 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 reposition to correct any position errors on the label tape.
