Classification and working principle of labeling machine


1. Labeling machine-Introduction

Labeling machine It is a device for sticking rolls of self-adhesive paper labels (paper or metal foil) on PCBs, products, or prescribed packaging. The labeling machine is an indispensable 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.

2. Classification of labeling machines

The main categories are automatic vertical round bottle labeling machine, automatic horizontal round bottle labeling machine, automatic corner labeling machine, automatic wine labeling machine, flat labeling machine, automatic flat assembly line labeling head, Upper and lower self-adhesive labeling machine, double-sided pneumatic labeling machine, single-sided labeling machine, semi-automatic flat labeling machine, semi-automatic round bottle labeling machine, etc.

1) Flat labeling machine

Realize the labeling and filming on the upper plane and upper arc surface of the workpiece, such as boxes, books, plastic cases, etc. There are two methods of rolling and sucking. The selection is mainly based on efficiency, accuracy, and bubble requirements.

2) Round bottle labeling machine

Achieve labeling or filming on the circumferential surface of cylindrical and conical products, such as glass bottles, plastic bottles, etc. It can realize the functions of circumference, half circumference, circumference double-sided, circumference positioning labeling, etc., mainly vertical labeling and horizontal Type labeling in two ways.

3) Side labeling machine

Realize labeling or filming on the side plane and side arc surface of the workpiece, such as flat cosmetic bottles, square boxes, etc., can be equipped with round bottle labeling equipment and realize round bottle labeling at the same time.

3. Working principle of labeling machine

At the beginning of the working process, the box is fed to the labeling machine at a constant speed on the conveyor belt. The mechanical fixing device separates the tubes by a fixed distance and pushes the boxes along the conveyor belt. The automated system of the labeling machine includes a driving wheel, a labeling wheel, and a reel. The driving wheel drags the label tape intermittently, the label tape is pulled out from the rotation, and the labeling wheel will press the label tape on the box after passing through the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label tape. Because the labels are closely connected to the label tape, the label tape must constantly start and stop.

The label is attached to the box when the labeling wheel moves simultaneously as the box. When the conveyor belt reaches a particular position, the label belt drive wheel will accelerate to a speed that matches the conveyor belt. After the label is attached, it will decelerate to a stop.

Since the label belt may slide, there is a registration mark to ensure that each label is placed correctly. A sensor reads the registration mark. During the deceleration phase of the label tape, the drive wheel will readjust its position to correct any position errors on the label tape.
