Several common labeling methods for labeling machines
With the development of society, the trend of mechanized equipment replacing manual labor is becoming more and more obvious. Automatic labeling machines replace manual labor to solve practical problems such as poor manual labeling effect and labor-intensive labeling. Although there are many types of labeling machines on the market, there are only a few labeling methods for labeling machines. Let's take a look at several common labeling methods for labeling machines.
The working principle of the rubbing method: When labeling, when the leading edge of the label adheres to the package, the product immediately takes the label away. In this type of labeling machine, this method can only succeed when the speed of the package passing is consistent with the label distribution speed. This is a technology that requires continuous operation, so its labeling efficiency is greatly improved, and it is mostly suitable for high-speed automated pharmaceutical packaging production lines. When the leading 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, while the labeling accuracy depends on the speed of the product passing through the labeling machine and the speed of label distribution. If the speeds of the two are the same, the labeling accuracy is high, otherwise, the accuracy of the labeling machine will be affected.

The working principle of the suction method: When the label paper of the labeling machine leaves the conveyor belt, it is sucked onto the vacuum pad, which is connected to the end of a mechanical device. When the mechanical device stretches until the label contacts the product, it shrinks back, and the label is attached to the product. The advantages of this method are high accuracy and it is suitable for the labeling process of difficult packaging products; the disadvantages are slow labeling speed and poor labeling quality.

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 plane covered with hundreds of small holes. The small holes are used to maintain the formation of "air jets". A stream of compressed air is blown out by these "air jets". The pressure is very strong, which moves the label on the vacuum grid and allows it to be attached to the product. The advantages of this method are high precision and reliability; the disadvantages are complex process and high cost.

The above are the common labeling methods of labeling machines. I hope it will be helpful to you.
