The working process of the automatic labeling machine begins with the box being 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 direction of the conveyor belt. The mechanical system of the labeling machine includes a drive wheel, a rotary automatic labeling machine, 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 passes through the labeling wheel, the labeling wheel will press the label tape on the box. 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 be constantly started and stopped.

　　The label is applied to the case with the labeling wheel moving at the same speed as the case. 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.

　　Since the label belt 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, and during the tape deceleration phase, the drive wheels are repositioned to correct any mispositioning on the tape.
