What are the commonly used labeling methods for labeling machines? With the development of the economy and the improvement of people's living standards, each commodity in circulation needs to indicate the production date and shelf life and other relevant information.
The goal is the way to achieve it
.

Labeling machine is a machine that adds labels to packaging or products.
It not only has a beautiful effect, but more importantly, it can track and manage product sales, especially in medicine, food and other industries.
If there is an abnormality, it can be accurate and timely.
to initiate a product recall mechanism
.

Labeling machines are an integral part of modern packaging
.

At present, the types of labeling machines produced in China are gradually increasing, and the technical level has also been greatly improved.
It has shifted from the backward situation of manual and semi-automatic labeling to the pattern of automatic high-speed labeling machines occupying the vast market
.

At present, the labeling machine has three labeling methods as follows: 1.
Suction method (or air suction method) This is a common labeling technology.
When the label paper leaves the conveyor belt, it is distributed on the vacuum pad, which is connected to a mechanical device.
end
.

When the mechanism is extended until the label is in contact with the package, it is retracted, at which point the label is attached to the package
.

This technique reliably achieves correct labeling with high accuracy and is ideal for top or side labeling of product packages with varying heights, or for side labeling of packages that are difficult to move Yes, but its labeling speed is slower and the labeling quality is average
.


2.
Blow-on method (or jet method) Some operating modes of this technology are similar to the above-mentioned suction method, that is, the label is placed on the surface of the vacuum pad and fixed until the sticking action starts
.

However, in this method, the vacuum surface is kept stationary, and the label is fixed and positioned on a "vacuum grid", which is a flat surface with hundreds of small holes, which are used to maintain the formation of "air" jet"
.

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 packaged item
.

This is a complex technology with high precision and reliability
.


Third, the rubbing method (or brushing method) This method is also called synchronous labeling method
.

In labeling, the product takes away the label immediately after the leading edge portion of the label is attached to the package
.

In this type of labelling machine, this method can only be successful if the package passing speed is consistent with the label dispensing speed
.

This is a technology that needs to maintain continuous operation, so its labeling efficiency is improved, and it is mostly suitable for high-speed and high-speed automatic packaging production lines
.


This type of method generally has low labeling accuracy
.

However, the technology invented by our company (not introduced here) completely solves this problem, improves the labeling accuracy and equipment stability without affecting the efficiency at all, and reduces the difficulty of equipment adjustment
