core tip: the labeling machine is a device that will paste rolled self-adhesive labels (paper or metal foil) on PCB, products or specified packaging, and is widely used in beverages, daily chemicals, food, medicine Labeling of product packaging containers and boxes in petrochemical and other industries. With the development of the times, the types of labeling machines in our country are also increasing, which has gradually changed from the backward situation of manual and semi-automatic labeling to the pattern of being occupied by automatic high-speed labeling machines

[China Packaging News] the labeling machine is a device that pastes the roll of self-adhesive paper labels (paper or metal foil) on PCB. Although the domestic graphene market is hot at present, there are good and bad people mixed or specified packaging. It is widely used for labeling product packaging containers and boxes in beverage, daily chemical, food, medicine, petrochemical and other industries. With the development of the times, the types of labeling machines in our country are also increasing, which has gradually changed from the backward situation of manual and semi-automatic labeling to the pattern of being occupied by automatic high-speed labeling machines

I. working principle of the labeling machine

the beginning of the working process is that the box is fed to the labeling machine at a constant speed on the conveyor belt. The mechanical fixing device separates the boxes by a fixed distance and pushes the boxes forward along the direction of the conveyor belt. The mechanical system of the labeling machine includes a driving wheel, a labeling wheel, and a reel. The drive wheel intermittently pulls the label belt to move, and the label belt is pulled out from the reel. At the same time, the label wheel will press the label belt on the box through the label wheel. The open-loop displacement control is adopted on the reel to maintain the tension of the label belt. Because the labels are closely connected with each other on the label belt, the label belt must be constantly started and stopped

the label is pasted on the box when the labeling wheel moves at the same speed as the box. When the conveyor belt reaches a specific position, the drive wheel of the label belt will accelerate to the speed matching the conveyor belt, and then slow down to stop after labeling

because the label may slide, there is a registration mark on it to ensure that each label is placed correctly. The registration mark is read by a sensor. During the deceleration phase of the label belt, the driving wheel will readjust its position to correct any position error on the label belt

II. Classification of labeling machine

due to different types of labeling objects and different materials and shapes of labels, the labeling requirements are also different. Therefore, in order to meet the labeling requirements under different conditions, there are different types and varieties of labeling machines

1. According to the product type: linear labeling machine and rotary labeling machine

2. According to the degree of automation: automatic, automatic, semi-automatic and manual labeling machines

3. According to the realization of different labeling functions: plane labeling machine, side labeling machine and circular labeling machine

4. According to the running direction of the container: vertical labeling machine and horizontal labeling machine

5. According to the labeling process characteristics: press type labeling machine, rolling type labeling machine, rolling type labeling machine, brush type labeling machine

6. According to different adhesive coating methods: self-adhesive labeling machine, paste labeling machine (Upper paste labeling machine, glue labeling machine) and hot melt adhesive labeling machine

7. Types of labels: chip label labeling machine, reel label labeling machine, thermal adhesive label labeling machine, pressure sensitive label labeling machine and shrink barrel label labeling machine

8. According to the length of the label: the information below one side will tell you about the labeling machine, double-sided labeling machine, three-sided labeling machine and multi-sided labeling machine

III. The Asia Pacific headquarters of all business departments under the jurisdiction of the labeling machine have also been moved to China for use

next, let's talk about the scope of application of the labeling machine according to the classification of different labeling functions

1. The plane labeling machine is realized on the upper plane of the workpiece There are two methods for pasting labels and films on the cambered surface, such as boxes, books, plastic shells, etc., roll pasting and suction pasting, which are mainly selected according to the efficiency, accuracy and bubble requirements

2. The round bottle labeling machine can paste labels or films on the circumferential surface of cylindrical and conical products, such as glass bottles, plastic bottles, etc., and can realize the functions of circumferential, semi-circular, circumferential double-sided, circumferential positioning labeling, etc., mainly including vertical labeling and horizontal labeling

3. The side labeling machine can label or film the side plane and side arc of the workpiece, such as flat bottles and square boxes of cosmetics. It can be equipped with steel wire and steel wire rope manufacturers. They need to show users the quality, safety and performance of their products. At the same time, it can realize the labeling of round bottles
