As an indispensable machine on the production line, the labeling machine has always been a popular product in the industry. Although it is used, there are still many friends who do not understand the label machine, especially in different types of labeling machine labeling methods. Then What are the labeling methods? Let me introduce it to you
The common ones are the blow stick method, the wipe stick method and the suction stick method.
The suction method is that when the labelling machine label paper leaves the conveyor belt, it is sucked onto the vacuum pad, and the vacuum pad is connected to the end of a mechanical device. When the mechanism extends to the point where 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 blow method is improved on the basis of the sucking method, the difference is that the surface of the vacuum pad remains unchanged, and the label is fixed and positioned on a "vacuum grid", which is a flat surface covered with hundreds of small hole. 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.
The wiping method is that when the front edge of the label of the labeling machine is pasted on the product, the product immediately takes away the label. 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.
Compared with the above 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.
