How much do you know about the labeling machine?

Labeling machine is a device that sticks rolls of self-adhesive paper labels (paper or metal foil) on products or specified packages. labeling machines are an integral part of modern packaging.

What are the conveying mechanisms of the labeling machine?

The conveying mechanism of the labeling machine can realize the automatic conveying of the product: send the product to the labeling position, and automatically send the attached object away after the label is applied. From the rigidity of the conveying mechanism, the deviation of the conveyor belt, the conveying noise, Power is measured in four aspects, mainly used for automatic labeling machines.

1. Label covering mechanism: used to provide pressure to make the label and product adhere more firmly.

2. Guiding mechanism: It is used to guide the product during the conveying process to prevent the product from shifting left and right during the conveying process.

3. Electric box: used to place the electric control circuit of the labeling machine and support the entire labeling mechanism.

4. Automatic feeding mechanism: It can store a part of the objects to be attached, and can realize the automatic supply of the objects to be attached, without the need to manually put them one by one.

5. Electronic control system

What are the main parameters of labeling machine?

Labeling rate

Percentage of the number of packaging containers labelled according to the labelling requirements (single or multi-label) to the total number of packaging containers inspected.

Loss rate

During the labeling process, the percentage of the number of labels damaged by the labeling machine to the total number of labels consumed when labeling the inspected packaging container.

Positive rate

In the packaging containers inspected, the percentage of the number of positive packaging containers to the total number of packaging containers inspected.

How to solve the problem of continuous labeling of the labeling machine?

1. Trouble of measuring target electric eye

Solution: Place the label in the detection area of the electro-optical eye, slide the label to obtain and disconnect the signal, and observe whether the signal light flashes on the IO monitor on the touch screen. If the signal light does not flash, the electric eye may be faulty or the connector at the connection point is loose.

2. The label paper does not pass through the detection area of the target electric eye

Solution: Install the label paper through the detection area of the target electric eye.

3. Dust, powder, broken labels, etc. block the detection end of the electric eye

Solution: Clean the electric eye in time, pay attention to cleaning in dry conditions, do not use cleaning tools such as damp cloth.

4. The effective signal of the target electric eye is not adjusted well

Solution: reset the target sensor. (Set according to the operation procedure in the manual of each type of target measuring sensor)

5. The type of target measuring eye used is invalid for the material and nature of the label itself. If a transparent label is used on the device, but the detection sensor is an ordinary target sensor, it may occur that the label is continuously peeled off after the sensor senses the object to be measured.

Solution: replace the target measuring eye with the corresponding nature that can normally detect valid signals.
