Anzhen packaging machinery introduces three kinds of labeling methods for self-adhesive automatic labeling machine

Self-adhesive automatic labeling machine is suitable for labeling round plastic bottles, glass bottles, etc. in similar industries such as pharmaceutical, food, light industry and daily chemical industries. The machine can automatically complete the bottle separation, the labeling belt, the synchronous separation label, the label and the automatic printing batch number, and the writing is clear.

Here are some of the main labeling methods introduced by Shanghai Anzhen Packaging Machinery Factory:

1. "Sucking method" (or "air suction method")

This is ZUI's common labeling technique, which distributes the label paper onto the vacuum pad as it leaves the conveyor belt and the vacuum pad is attached 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 correct labeling with high precision. This method is very suitable for top labeling with a certain change in the height of the product package, or for side labeling of difficult-to-handle packages, but it is very suitable. The labeling speed is slower.

2. "Scratch method" (or "brushing method")

The third method of labeling is called synchronous labeling, and can also be called "wiping method", "brushing method" or "contact pasting method". At the time of labeling, when the leading edge portion of the label adheres to the package, the product immediately removes the label. In this type of labeling machine, this method can only be successful if 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 pharmaceutical packaging production lines.

3. "Blowing method" (or "jet method")

Some of the techniques of this technique operate in a similar manner to the above-described suction method by placing the label on a vacuum surface 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 on it, which are used to maintain formation" Air jets." A stream of compressed air is blown from these "air jets" and the pressure is strong, causing the label on the vacuum grid to move and attach it to the packaged item. This is a complex technology with high precision and reliability.

In addition, a second device such as a brush or roller is indispensable for the attachment of the label to meet the complete and appropriate requirements.

Among the above three methods, * and the third method are often used for labeling wet adhesive labels, and the second method is mainly used for labeling of self-adhesive labels .

With the improvement of people's living standards and the popularity of the network, security protection has become more and more popular. Especially in recent years, the development of information technology and the improvement of people's living environment have enhanced people's awareness of family safety. Home network video monitoring, with its seamless compatibility with IP network in technology, remote real-time video processing capability and other network applications, has rapidly become the fastest growing product in the market with an annual growth rate of 40% since its appearance, and its market demand is unlimited.

Thanks to the rapid economic development, people's life rhythm is getting faster and faster, and there will be less and less time to take care of and understand their families. However, the rapid development of modern science and technology is making it possible to take care of children, family pets remotely and monitor family conditions in real time. When people are busy working or traveling, they can learn their family profile remotely and make timely analysis and judgment according to the situation. In this case, the application of home surveillance Network Camera is particularly urgent. In fact, home network video monitoring is an inevitable product of social development, and it is an individual's security requirement for the social unit cell - the family.
