Self-adhesive labelers are the most common type of labelers in recent years, and their technology is rapidly improving. For pharmaceutical manufacturers, whether from the labeling production equipment, or from the self-adhesive label and the bottle body to be labeled, it will raise higher requirements. Faced with the domestic market of adhesive labeling machines with different strengths and weaknesses, how pharmaceutical manufacturers can choose a cost-effective adhesive labeling machine will be a concern. Throughout the domestic and international self-adhesive labeling machines, their working principles are similar, they are all made by label peeling and transferring and rolling, but their control and manufacturing are not the same.
In the past, the labeling position detected by the self-adhesive labeling machine was based on the front edge of the bottle body as a photosensitive point. Because bottles of different diameters need to be moved by the corresponding electric eye or the labeling time is changed, if this change is not made, the labeling cannot be guaranteed. In the required position for each bottle. Now the products have the function of “automatically calculate the label length”, which can effectively make up for the above weaknesses. In terms of controlling the speed synchronization, in addition to the above-mentioned "automatic label length calculation" function, the self-adhesive labeling machine should also automatically adjust the conveyor belt speed, label speed, and label length. The difference between self-adhesive labeling machines is the guarantee of labeling quality stability. The control speed of the traditional self-adhesive labeling machine is adjusted by human experience, and the difficulty of artificial adjustment is that it is difficult to synchronize all the actions. Without synchronization, the labeling process will frequently change, resulting in poor labeling quality.
