Self-adhesive labeling machines are playing an increasingly important role in the packaging industry. Over the years, we have been committed to the development and production of self-adhesive labeling machines, and summarized the three labeling methods of self-adhesive labeling machines. Pros and cons. There are many types of self-adhesive labeling machines on the market, and everything is inseparable. The labeling methods of self-adhesive labeling machines mainly include rubbing method, blowing method and suction method. The standard methods also have their own advantages and disadvantages. The working principle of the rubbing method: When the front edge part of the label of the self-adhesive labeling machine is pasted on the product, the product immediately takes the label away. The advantage of this method is that the labeling speed is fast, and the labeling accuracy depends on the speed of the product passing through the sticker labeling machine and the speed of label distribution. If the speeds of the two are the same, the labeling accuracy is high, otherwise, do not dry The accuracy of the glue labeling machine will be affected. The working principle of the suction sticking method: When the label of the self-adhesive labeling machine leaves the conveyor belt, it is sucked onto the vacuum pad, which is connected to the end of a mechanical device. When this mechanical device stretches until the label is in contact with the product, it shrinks back, and the label is attached to the product at this time. The advantage of this method is that it has high labeling accuracy and is suitable for the labeling process of highly difficult-to-package products; the disadvantage is that the labeling speed is slow and the labeling quality is not good. The working principle of the blowing method: It has been improved on the basis of the suction method. The difference is that the surface of the vacuum pad remains stationary, and the label is fixed and positioned on a vacuum grid. The 'vacuum grid' is a flat surface with several Hundreds of small holes, small holes are used to maintain the formation of an 'air jet' blowing out a stream of compressed air, the pressure is very strong, so that the label on the vacuum grid moves, allowing it to be attached to the product. The advantage of this method is higher accuracy and reliability, but the disadvantage is that the process is complicated.
