Analysis of advantages and disadvantages of three labeling methods of labeling machine
Labeling machines are playing an increasingly important role in the packaging industry. Over the years, our company has been committed to providing high-end barcode series products and overall labeling solutions. The accumulated experience has allowed us to summarize the three labeling methods of labeling machines. Advantages and disadvantages. There are many kinds of labeling machines on the market, but the same is true. The labeling methods of labeling machines mainly include rubbing, blowing and suction. These three labeling methods also have their own advantages and disadvantages. The working principle of the rubbing method: when the front edge of the label of the 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 labeling machine and the speed of label distribution. If the two speeds are the same, then the labeling accuracy is high, otherwise, the labeling machine accuracy will be affected. influences. How the suction method works: When the labeler label paper leaves the conveyor belt, it is sucked onto the vacuum pad, which is connected to the end of a mechanical device. When the mechanism extends until the label comes into contact with the product, it contracts back, at which point the label is attached to the product. The advantage of this method is that it has high precision and is suitable for the labeling process of difficult packaging products; the disadvantage is that the labeling speed is slow and the labeling quality is not good. The working principle of the blow-and-stick method: improved on the basis of the suction-stick method, the difference is that the surface of the vacuum pad remains unchanged, and the label is fixed and positioned on a 'vacuum gridHundreds of small holes. Small holes are used to maintain the formation of 'air jets'. These 'air jets' blow out a burst of compressed air with strong pressure that moves the label on the vacuum grid, allowing it to attach to the product. The advantages of this method are higher accuracy and reliability; the disadvantage is that the process is complicated. Comparing the three labeling methods, it is found that the wiping method can greatly improve the working speed of the labeling machine, which is in line with the development trend of pursuing high efficiency.
