Judging from the current situation, the automatic labeling machine has basically replaced the traditional manual labor. Now there are many automatic labeling machines on the market, and there are many types of them. The automatic labeling machine is widely used, but It is not without its shortcomings. Let’s take a look at the automatic labeling machine.
Advantages and disadvantages:
The working principle of the automatic labeling machine rubbing method: When the automatic labeling machine is labeling, when the leading edge of the label is adhered to the package, the product will immediately take the label away. In this kind of labeling machine, this method can only be successful when the passing speed of the package is consistent with the label dispensing speed. This is a technology that needs to maintain continuous operation, so its labeling efficiency is greatly improved, and it is mostly suitable for high-speed automated medical packaging production lines. When the front edge of the label of the labeling machine is attached to 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 automatic labeling machine and the speed of label distribution. If the two speeds are the same, the labeling accuracy is high, otherwise, the labeling machine accuracy will be affected. The working principle of the suction sticking method: When the label paper of the automatic 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 to the point where 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 precision and is suitable for the labeling process of 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 is 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 and is covered with Hundreds of small holes. Small holes are used to maintain the formation of “air jets”. From these “air jets”, a stream of compressed air is blown out, and the pressure is very strong, which moves the label on the vacuum grid and allows it to be attached to the product. The advantage of this method is higher accuracy and reliability; the disadvantage of the automatic labeling machine is that the process is complicated and the cost is higher. In the analysis of the advantages and disadvantages of the above three labeling methods, it is found that the rubbing method can greatly improve the working speed of the labeling machine, which is in line with the development trend of pursuing high speed.
