The application of the automatic labeling machine has greatly improved the efficiency of label attachment and the overall production capacity. The automatic labeling machine has accurate attachment position, excellent quality, and high stability; avoiding low efficiency of manual labeling and skewed attachment A series of problems such as wrinkling and labeling make the product more beautiful and improve the appreciation of product packaging. It can effectively reduce the waste of packaging materials, reduce the labor cost of labeling, improve the aesthetics of product logos, and enhance the overall competitiveness of products. What is the working principle of the automatic labeling machine? How can it achieve exquisite labeling "good" and "fast" like thousands of skillful hands?

　　There are many types of automatic labeling machines with different functions, but the basic principles are similar. The working principle of the automatic labeling machine is simply that the label is peeled off, transferred and rolled onto the object to be labeled. The working process is like this, the product moves to the labeling machine at a constant speed on the conveyor belt. The fixtures on the machine will evenly space the products at a certain distance to facilitate labeling, and the products are still traveling along the conveyor belt to the labeling system. The automatic labeling mechanical system includes a driving wheel, a labeling wheel, and a reel. The drive wheel intermittently pulls the tape in motion, and the tape is pulled from the reel and past the applicator wheel, which presses the tape onto the product. Labels are applied to products with the applicator wheel moving at the same speed as the product. When the conveyor belt reaches a certain position, the label belt driving wheel will accelerate to match the speed of the conveyor belt, and after labeling, it will decelerate until it stops.

　　Since the label tape may slip during movement, it has clear marks on it to ensure that each label is placed correctly. These marks are read by a sensor, and during the tape deceleration phase, the drive wheels are repositioned to correct any mispositioning on the tape. This provides a strong guarantee for accurate labeling of products.

　　For the labeling of packaging containers such as bottles and cans, there are currently two long-used labeling methods: straight line sticking and circular sticking.

　　Straight-line pasting means that the container moves forward in an upright shape, and the label coated with adhesive is pasted on the designated position of the container. One is that the container moves forward intermittently, and the label is pasted when the container is not moving; The label is sent to the predetermined station for pasting; the third is to synchronize the moving speed of the label coated with the adhesive with the container for tangential pasting. And it can stick the label to the body, neck and shoulder of the bottle synchronously. According to the different products produced and the different labeling positions, the corresponding machines can be found according to the needs. Circular pasting is to make the bottle lie horizontally and paste the label during the rotation process.
