Analysis on the labeling method of self-adhesive labeling machine industry

The self-adhesive labeling machine has the advantages of clean and sanitary, no mildew, beautiful, firm after labeling, no self falling off, high production efficiency Self adhesive automatic labeling machine is suitable for labeling circular plastic bottles, glass bottles or similar objects in pharmaceutical, food, light industry, daily chemical and other industries The machine can automatically divide bottles, send label tape, separate labels synchronously, label and print batch number automatically with clear handwriting Here are several main labeling methods: 1 "Suction method" (or "air suction method") is a general labeling technology of Zui When the label paper leaves the conveyor belt and is distributed on the vacuum pad, the vacuum pad is connected to the end of a mechanical device When the mechanism extends to the point where the label contacts the package, it shrinks back and attaches the label to the package This method is very suitable for the top labeling with certain changes in the height of the product package, or for the side labeling of the package which is difficult to move, but its labeling speed is slow 2 Some operation modes of the "blowing and sticking method" (or "jet method") are similar to the above-mentioned suction and sticking method, that is, the label is placed on the vacuum surface pad and fixed until the sticking action begins But in this method, the vacuum surface is fixed, and the label is fixed and positioned on a "vacuum gate", which is a plane with hundreds of holes on it, which is used to maintain the formation of "air jet" These "air jets" blow out a stream of compressed air, which has a strong pressure, so that the label on the vacuum grid moves, and it is attached to the packaged goods It is a complex technology with high precision and reliability 3 The third labeling method of "wipe and stick method" (or "brush and stick method") is called synchronous labeling method, which can also be called "wipe and stick method", "brush and stick method" or "contact and stick method" When labeling, when the leading edge of the label is attached to the package, the product immediately takes the label away In this kind of labeling machine, this method can be successful only when the speed of package passing is consistent with the speed of label distribution This is a technology that needs to maintain continuous operation, so its labeling efficiency is greatly improved, and it is mostly suitable for high-speed and automatic pharmaceutical packaging production line In addition, a second set of devices, such as a brush or roller, is also indispensable for the label to be attached to meet the complete and appropriate requirements Among the above three methods, * and the second method are commonly used for labeling of wet adhesive labels, and the third method is mainly used for labeling of self-adhesive labels.
