Maintenance of flexo printer slotter die cutter is the key to ensure its stable operation and extend its service life. The following is a detailed maintenance method:
1. Regular maintenance
Lubrication maintenance
Flexo printer slotter die cutter tracks, bearings, etc. need to be lubricated about once every 6 months in the early stage, and once every 4 months after one year. According to the frequency of use and working environment of the machine, choose a suitable lubricant to lubricate the transmission parts, bearings, etc., reduce component wear and extend the service life of the equipment.
Screw inspection
Check the visible screws on the machine every six months to prevent the screws from falling and damaging the machine
Ground wire inspection
Check the ground wire every six months to see if it is completely connected to it to prevent it from loosening or being removed by others
Environmental maintenance
Ensure the cleanliness of the use environment of flexo printer slotter die cutter, keep the temperature between 10 degrees and 30 degrees, and the relative humidity between 30% and 50%.
Ensure the cleanliness of the printed surface of the cardboard. When printing double-layer or multi-layer cartons, adjust the height of the machine head to prevent scratching the nozzle. Keep the machine nozzle sealed when it is not working for a long time.
2. Maintenance of important parts
Gears, cams, sprockets, rollers and bearings
These parts are important parts in flexo printer slotter die cutter. When maintaining them, pay attention to the differences from other parts, because the difference in precision will affect the printing quality. Regularly check the accuracy changes and damage degree of these parts. If there are problems such as severe wear and looseness, they should be replaced or adjusted in time.
Spring
The spring is a component used more in the force balance mechanism, and its working quality directly determines the matching accuracy between the moving parts. The spring must have sensitive elasticity, while hysteresis elasticity and irreversible plastic deformation are not conducive to the work of the spring. If the above problems are found, the spring must be replaced immediately.

3. Maintenance of ink system
Ink roller and anilox roller
If the surface is worn or the ink is dried, it will cause uneven inking. Minor wear can be repaired by grinding, and severe wear needs to be replaced: the dried ink should be soaked and wiped with a special solvent.
Ink pump and ink tube
The blockage of the ink pump and ink tube will affect the ink supply. Regularly check the working status of the flexo printer slotter die cutter ink pump, clean or replace the blocked ink tube and filter to ensure smooth ink circulation.
4. Electrical system maintenance
Electrical components
Check whether the connection of the electrical components of the flexo printer slotter die cutter is loose, whether the terminal is oxidized and corroded, and tighten, clean or replace them in time if there is any problem.
Motor
Disassemble the motor, clean the internal winding, replace the bearing lubricant, check the wear of the carbon brush, and ensure that the motor runs smoothly and the power output is stable.
Control system
Use professional testing instruments to test the control system of the flexo printer slotter die cutter, calibrate the sensitivity of the sensor, check whether the electronic components on the circuit board have cold soldering, damage, etc., to ensure the normal automation control functions of the printing press, such as paper detection, registration control, and ink balance control.
