Labeling machine three kinds of labeling methods
Labeling machines are also an integral part of modern packaging. Nowadays, the types of labeling machines are gradually increasing, and the technical level has also been greatly improved. From the backward situation of manual and semi-automatic labeling, to the automatic high-speed labeling machine.
The labeling machine has three labeling methods: First, the suction labeling method is a common labeling technique. When the label paper leaves the conveyor belt, it is distributed to the vacuum pad, and the vacuum pad is connected to the end of a mechanical device. When the mechanism is extended until the label comes into contact with the package, it is retracted and the label is attached to the package. This technology reliably achieves the correct labeling with high precision. This method is suitable for top or side labeling with a certain change in the height of the product package, or for side labeling of difficult-to-handle packages. However, its labeling speed is slower and the labeling quality is average.
Second, some of the modes of operation of the technique of blowing paste are similar to the above-described method of suction, in that the label is placed on the surface pad of the vacuum pad until the attachment action begins. However, in this method, the vacuum surface is kept stationary, the label is fixed and positioned on a "vacuum grid", and the "vacuum grid" is a plane having hundreds of small holes thereon, and the small holes are used to maintain the formation of "air" Jet." A stream of compressed air is blown from these "air jets", which is very strong, moving the label on the vacuum grille and attaching it to the packaged item. This is a complex technology with high precision and reliability.
Third, the method of rubbing is also called synchronous labeling. When labeling, when the leading edge portion of the label is pasted onto the package, the product immediately takes the label away. In this type of labeling machine, this method can only be successful when the speed of the package is consistent with the speed at which the label is dispensed. This is a technology that requires continuous operation, so its labeling efficiency is greatly improved, and it is suitable for high-speed and efficient automated packaging production lines.
