With the continuous improvement of the level of automated packaging, labeling machines, as indispensable equipment on modern production lines, are widely used in food, medicine, daily chemicals, chemicals, electronics and other industries. Its role is not only to attach labels accurately to products or packaging but also to be an important means for enterprises to improve efficiency, standardize production, and enhance brand image. However, many users often ignore some details in the process of using labeling machines, resulting in problems such as inaccurate labeling, equipment failure, and label waste.

In order to help users use labeling equipment more scientifically and safely, this article will focus on the precautions for using labeling machines, covering pre-operation preparation, operation process monitoring, daily maintenance and common fault prevention, etc., to help enterprises achieve efficient and stable labeling operations.

1. Preparation before operation

Although the labeling machine is a piece of highly automated equipment, the preparation before operation is still crucial, which is directly related to the operating status of the equipment and the quality of labeling.

1.1 Check the equipment status

Before starting the labeling machine, the following aspects should be fully checked:

Is the power supply voltage normal? avoid unstable voltage, burning the circuit system;

Is the air pressure in line with the requirements (for pneumatic labeling machines): usually stable between 0.4~0.6MPa;

Are the transmission parts loose or abnormal? The chain, belt, guide rail, and other parts should not be loose or make abnormal sounds.

Is the status of each sensor normal, including photoelectric switches, identification sensors, etc., should ensure sensitive sensing.

Clean labeling environment: keep the equipment free of oil stains and dust to prevent labels from slipping or failing to adhere.

1.2 Label and product matching and debugging

The label roll direction is correct: the label winding method must meet the equipment requirements, and the wrong direction will lead to inaccurate labeling.

The label size matches the mold: different products need to match different labeling tools, especially special-shaped bottles.

Precise labeling position setting: The labeling position needs to be accurately controlled through the operation panel or mechanical adjustment method.

The label peeling mechanism is debugged in place: the label should be able to be peeled smoothly without tearing.

2. Precautions during the operation of the labeling machine

Operational safety and real-time monitoring during equipment operation play a decisive role in ensuring labeling accuracy and product quality.

2.1 Non-operating personnel are strictly prohibited from approaching the operating equipment

When the labeling machine is running at high speed, high-speed moving parts such as the labeling head, conveyor belt, and rolling mechanism are dangerous. Non-professionals should not approach them at will to avoid accidental injuries or misoperation.

2.2 Real-time observation of labeling status

Whether the label is attached normally: check whether there are bubbles, wrinkles, skewness, label drop, etc..

Whether the product positioning is accurate: Position deviation will affect the labeling accuracy, and the conveying system needs to be monitored in real time.

Whether the label is missing or over-attached: generally caused by sensor failure or program setting error.

Synchronicity of label stripping speed and conveying speed: mismatch between the two can easily cause label tearing or skewed attachment.

2.3 Timely and accurate label roll replacement

When the label is about to run out, the operator should replace the label roll in time and ensure that:

The label interface is neatly pasted and cannot be overlapped.

The label reel and the unwinding mechanism are firmly fixed.

The new roll label is correctly inserted into the label stripping path from the starting position.

2.4 Emergency stop treatment measures

Once an abnormality occurs (such as label jamming, bottle collapse, equipment shaking, etc.), the emergency stop button should be pressed immediately, and do not force it to continue running. At the same time, the cause must be checked, and it can be restarted only after confirmation that there is no problem.

3. Precautions for labeling special products

3.1 Labeling of round bottles and conical bottles

For bottles with irregular shapes (such as conical bottles and cylindrical bottles), pay special attention to the following points when labeling:

Use a dedicated bottle positioning device or rotating mechanism to prevent labeling from being skewed.

Adjust the fitting angle of the pressure roller or rolling mechanism.

Confirm whether the bottle is dry and clean before labeling, otherwise, it is easy to debond.

3.2 Labeling of fragile or thin products

For light and deformable products such as test tubes, ampoules, and film bags, the labeling pressure and speed should be appropriately reduced, and suitable brackets or support devices should be equipped to prevent the products from being squeezed or thrown out during the labeling process.

4. Safety operation tips

It is strictly forbidden to operate with power on: the power must be cut off before repair or maintenance.

Operation training cannot be ignored: operators must undergo professional training before taking up their posts.

Label materials must match the machine model: different labeling machines correspond to different materials and viscosity requirements.

Regularly check accuracy: it is recommended to calibrate and test the labeling position deviation every month.

Spare parts are fully prepared: commonly used spare parts (such as sensors, label shafts, and guide wheels) should be in stock.

As an important part of the automated packaging process, the operating efficiency and labeling quality of the labeling machine have a direct impact on the overall image of the product and the efficiency of the enterprise. By operating the equipment scientifically and standardly, doing daily maintenance, and troubleshooting in a timely manner, the company can not only extend the service life of the equipment but also significantly reduce the labeling error rate and downtime rate.

The above "labeling machine use precautions" are not only the basic requirements for ensuring safe production, but also the key links to improve work efficiency and maintain brand image. Every equipment operator and manager should keep them in mind to truly maximize the value of the labeling machine.
