As an important equipment in the modern packaging industry, labeling machines are widely used in many industries such as food, medicine, daily chemicals, and electronics. For enterprises, an efficient and stable labeling machine can not only improve production efficiency but also reduce labor costs. However, any mechanical equipment will experience wear and failure during long-term operation, so regular maintenance is the key to extending the service life of the labeling machine. This article will introduce the maintenance points of the labeling machine in detail, and combine the professional suggestions of the labeling machine manufacturer to help enterprises improve the efficiency of equipment use.
1. Daily maintenance
1.1 Cleaning and maintenance
Keeping the labeling machine clean is the basis for ensuring its long-term and stable operation. Since the working environment of the labeling machine usually involves impurities such as glue, labels, and dust, if it is not cleaned in time, it may affect the labeling accuracy and even cause mechanical failure.
Daily cleaning: Use a clean soft cloth to wipe the main components of the labeling machine, such as conveyor belts, label rollers, and sensors.
Remove adhesive residues: Use an appropriate amount of alcohol or special detergent to clean the adhesive residues on the labeling head, pressure roller, and label peeling plate to avoid affecting the smooth delivery of the label.
Keep electrical components dry: The control panel, sensors, and other electronic components of the labeling machine should avoid humid environments to prevent short circuits.
1.2 Lubrication and maintenance
The labeling machine contains multiple moving parts, such as transmission shafts, rollers, gears, etc. The long-term operation will cause increased friction of parts. Therefore, proper lubrication can effectively reduce wear and ensure smooth operation of the machine.
Regularly add lubricating oil: Check the transmission part every week and lubricate it with special lubricating oil to avoid dry friction.
Avoid excessive use: Excessive lubrication may cause oil stains to contaminate labels or conveyor belts, so it should be used in moderation and excess lubricant should be wiped off.
1.3 Labeling accuracy adjustment
The labeling accuracy of the labeling machine directly affects the aesthetics and pass rate of the product, so it is necessary to check the labeling accuracy of the equipment regularly.
Check the sensor position: Make sure that the photoelectric sensor is aligned with the label and the product to avoid mis-sticking or missing.
Adjust the labeling pressure: According to the label material and the surface of the product, adjust the pressure of the pressure roller appropriately to ensure that the label is firmly and flatly pasted.
Test labeling speed: If the equipment has problems with deviation or misalignment, the speed of the labeling machine can be adjusted appropriately to match the conveyor belt speed.
2. Regular maintenance
In addition to daily maintenance, enterprises should also regularly conduct comprehensive maintenance on the labeling machine to prevent sudden failures and ensure long-term stable operation of the equipment.
2.1 Inspection of key components
Some key components of the labeling machine, such as motors, control panels, transmission systems, etc., need to be inspected regularly to prevent equipment failures due to aging or looseness.
Motor inspection: Check whether the motor runs smoothly and whether there is abnormal noise or overheating.
Conveyor system inspection: Check whether the conveyor belt is cracked or loose, and replace it if necessary.
Tighten screws: Regularly check whether the screws of the machine body and transmission parts are loose, and tighten them in time to prevent the equipment from vibrating more.
2.2 Sensor calibration
The sensor is an important part of the labeling machine. If the sensor senses abnormally, it may cause the label to be mislabeled or repeated.
Clean the sensor: Wipe the sensor with a dry cotton cloth to prevent dust from affecting the sensitivity of the sensor.
Recalibration: If the label positioning is deviated, the sensor position can be readjusted and a calibration test can be performed.
3. Operation Specifications
Training operators The normal operation of the labeling machine is inseparable from the standardized operation of the operator. Regular training of operators to improve their understanding of the labeling machine can effectively reduce the occurrence of human failures. Strictly follow the instructions for use of the machine, do not adjust the machine parameters at will, and avoid equipment damage due to improper operation.
4. Troubleshooting and emergency treatment
4.1 Troubleshooting
When the labeling machine fails, a comprehensive inspection should be carried out first to find out the problem. Common faults include inaccurate labels, machine stoppages, and conveyor belts.
When inaccurate labels occur, check the label sensor, labeling head, and conveyor system to ensure that there are no obstacles or damaged parts.
When the machine stops, check the electrical system, power supply, and electronic control components to ensure normal power supply.
When the conveyor belt does not move, check whether the transmission components such as motors, belts, and gears are normal.
4.2 Emergency treatment
In an emergency, the operator should stop the machine quickly and perform emergency treatment.
Turn off the power immediately to avoid more serious failures in the electrical system.
Check for any stuck objects and remove them in time.
If the problem cannot be solved, contact professional maintenance personnel for repairs.
The maintenance of labeling machines is very important for enterprises. Good maintenance can effectively improve the stability and service life of the equipment, reduce maintenance costs, and improve production efficiency. When purchasing labeling machines, enterprises should wholesale labeling machines through formal channels to ensure the quality of the equipment and long-term stable operation. Through regular cleaning, lubrication, precision adjustment, and troubleshooting, enterprises can greatly extend the service life of labeling machines and ensure the efficient operation of the production line.
