The working principle of the labeling machine is mainly to achieve accurate label sticking through the coordinated operation of various components. The following is a detailed introduction:

Label delivery and distribution
The unwinding wheel installs the roll label, its brake ensures stable label delivery, the buffer wheel adapts to the change of tension force to prevent material breakage, and the guide roller guides and positions the roll material. When the product reaches the labeling position, the sensor sends a signal, the drive wheel drives the label belt to move, and the label distribution mechanism takes a label from the roll label through air pressure or mechanical devices.

Label peeling and attachment
The peeling plate makes it easy for the label to be detached from the base paper, and the labeling roller smoothly attaches the label to the object to be attached. For round bottle products, the bottle separation mechanism separates the bottles one by one. When the bottle reaches the predetermined labeling position, the sensor triggers the labeling action, and the drive wheel controls the movement of the label belt to accurately attach the label to the bottle body. Then the labeling device makes the label more firmly attached.

Detection and control
The sensor detects the position, size and other information of the product, and transmits the signal to the labeling control system, such as PLC, for processing. The control system coordinates the actions of various components according to the preset instructions to ensure that the label is accurately attached. At the same time, the detection device monitors the labeling process to prevent abnormal situations such as missing or wrong labeling.

Other auxiliary functions
Some labeling machines are equipped with printers to print information on the label, counters to count the number of labels, and touch screens to facilitate parameter setting and operation monitoring.
