The role of labeling machines in enterprise production is increasingly recognized by more and more people. Although there are many types of labeling machines on the market, they are always the same. For many years, labeling machine manufacturer Longhai Huanyu has been committed to the research and production of labeling machines, summarizing the advantages and disadvantages of three labeling methods for labeling machines. The labeling methods for self-adhesive labeling machines mainly include wiping method, blowing method, and suction method.

1. The working principle of the wiping method: When the leading edge of the label of the labeling machine is attached to the product, the product immediately takes away the label. The advantage of this method is its fast labeling speed, and the labeling accuracy depends on the speed at which the product passes through the labeling machine and the speed at which the label is separated. If the two speeds are the same, then the labeling accuracy is high, otherwise, the labeling machine accuracy will be affected.

2. Working principle of suction pasting method: When the label paper of the labeling machine leaves the conveyor belt and is sucked onto the vacuum pad, the vacuum pad is connected to the end of a mechanical device. When this mechanical device extends to the point where the label comes into contact with the product, it contracts back and the label is attached to the product. The advantage of this method is high accuracy and it is suitable for labeling processes of difficult packaged products; The disadvantage is slow labeling speed and poor labeling quality.

3. Working principle of blowing method: Improved on the basis of 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", which is a flat surface covered with hundreds of small holes. Small holes are used to maintain the formation of an 'air jet'. These 'air jets' blow out a stream of compressed air with strong pressure, causing the labels on the vacuum grid to move and adhere to the product. The advantage of this method is high accuracy and reliability; The disadvantage is that the process is complex.

Comparing the above three labeling methods, it is found that the wiping method can greatly improve the working speed of the adhesive labeling machine, which is in line with the development trend of pursuing high efficiency. Longhai Huanyu has been committed to providing labeling solutions, combining intelligent control technology to produce high-precision and fast fully automatic labeling machines.
