Main factors affecting the accuracy of labeling in round bottle labeling machine

The round bottle labeling machine adopts self-adhesive reel labeling paper, and the labeling method adopts the rolling method to complete the labeling process. The self-adhesive labeling machine has cleanliness and no mold, and the labeling is beautiful, firm and does not fall off by itself. High productivity and other advantages.
The whole operation process of labeling includes several processes: taking the label, sending the label, simultaneously conveying the container, positioning, and then labeling, overwriting, and rolling. From the perspective of the process route, the factors affecting the accuracy of labeling include: container positioning accuracy, labeling accuracy, overlay accuracy and target precision.
The container is accurately positioned, and when the position of the watch label on the bottle is strictly required, strict positioning is required. Common positioning methods mainly use container shape positioning, such as pits on the container, mold clamping lines, photoelectric positioning points, etc., usually equipped with a servo mechanism to feedback adjustment of the container position.
Labeling accuracy, labeling, bottle rotation, label movement, there is a deviation, this deviation is a fatal blow to the labeling accuracy. Therefore, it is necessary to design a synchronization mechanism. At the instant of labeling, the bottle rotation speed and the extension speed are equal to achieve relative static and improve the labeling accuracy.
Overlay and marking accuracy, the label attached needs to be overlaid and labeled to make it adhere to the bottle, but at the moment of contact, the label and the bottle are easy to slide, affecting accuracy. Therefore, the design of the overlay and target should be reasonable.
In addition, the instability of the conveyor belt, the error of the detection tool itself, the deviation of the bottle when rotating, and other factors will affect the accuracy of labeling. When designing the labeling machine, it is necessary to consider the actual situation.
