Introduction to Flute Laminator
The role of the Flute Laminating Machine
The Flute Laminating Machine play an important role in the packaging industry. These machines are dedicated to the high-precision laminating and bonding of pre-printed color printing facings to corrugated board. This process is indispensable in carton production, and it greatly improves productivity and product quality.
Why does it need to be maintained
After a long period of high-speed operation of the machine, wearing parts and other key components are likely to wear out or malfunction, which will have a direct impact on productivity and finished product quality. Therefore, it is very important for the machine to make accurate daily and periodic maintenance.
Routine maintenance measures
Production operation and maintenance
During the laminating process, the machine speed should not be too fast if the top paper is thin or curled. At the same time, the upper/lower chain stroke, the relative position of the paper stopping limit device and the cardboard need to be precisely adjusted to ensure the laminating accuracy. Adjust the production speed and stroke of the machine in a timely manner based on the characteristics of face paper and corrugated cardboard.
Feeder mechanism and adjustment
Pay attention to the front gauge of the paper feed chain and the upper/lower chain to ensure that there is no looseness or friction. Clean and lubricate each movable part in due time to ensure the stability and precision of the paper feeding process. Pay special attention to adjusting the position of the paper press steel slats to maintain proper friction with the cardboard to avoid problems caused by the inertial impulse generated by high-speed movement.
Cyclical Maintenance
Replacement of wearing parts and complete inspection
It is very important for periodic replacement of wear parts such as bearings, chains, gears, etc. As wear and tear of these parts will affect the normal operation of the machine. Comprehensive maintenance checks include electrical systems, mechanical components, etc. to ensure that all systems are in optimal condition.
Adjustment of upper/lower rollers
Gap adjustment of the upper/lower rollers is another critical periodic maintenance task. Inadequate clearance can cause shifting or blistering between the top sheet and the corrugated board, and may even lead to deformation of the corrugated board under pressure. Therefore, this gap must be precisely adjusted to the thickness of the board.
Choosing the right lubricant for maintenance is crucial
Lubrication plays a key role in the maintenance of Laminating Machine. Accurate lubrication not only reduces the wear and tear of the machine parts in motion, but also effectively reduces noise and extends the service life of the machine. Specifically, the machine’s rolling bearings, sliding bearings, swinging components, and various types of movable contact parts all require regular lubrication.
Lubrication Oil Schedule
Below is a detailed lubrication maintenance schedule that lists the type and grade of oil and refueling intervals required for each component:
Rolling bearings (both ends of each roller): No. 1 or No. 2 calcium-based lubricating grease is recommended, and the refueling cycle is once a week.
Rolling bearings (both ends of each roller): Optionally, you can use No. 46 oil, but the refueling intervals are much shorter and need to be done at least once per shift, i.e. at least once per day.
At each connecting rod moving part and crankshaft mechanism mating place: the recommended oil is No. 46, and the refueling cycle is at least once per shift, i.e., at least once per day.
All moving parts (movable places): the same recommended oil is No. 46, with a refueling cycle of at least once per shift, that is, at least once per day.
Gear drive (where gears mesh): Recommended No. 1 or No. 2 calcium-based lubricating grease, with monthly refueling intervals.
Motor bearings (ball bearings): No. 3 calcium-based grease is recommended, and the refueling cycle is once a year.
Lubricant Maintenance Considerations
Choose the right oil: Different machine parts require different types and grades of oil due to their different roles and properties. Be sure to choose according to the lubrication table, and do not change at will.
Oil preservation and use: Lubricants should be stored in clean, sealed containers to avoid contamination of the oil. It should be shaken well before use to ensure that the properties of the oil are homogeneous.
Regular refueling and maintenance in strict accordance with the lubrication table can effectively ensure the stable operation and prolong the service life of the Laminating Machine.
