To ensure the stable operation of the high-speed Flexo printer die cutter slotter machine, a comprehensive system covering daily maintenance, regular maintenance, precise operation, and rapid response to faults needs to be established. The specific measures are as follows:

1、 Standardized daily operation and maintenance

Thoroughly clean management

Clean the ink residue and paper scraps on the surface of the printing drum, ink path system, and paper feeding/receiving components (such as nozzles and chains) after daily shutdown to prevent drying, clogging, or affecting positioning accuracy. Use specialized cleaning agents to avoid corrosion of components.

Wipe the device casing and heat dissipation port to ensure good ventilation and avoid dust accumulation that may cause overheating or electrical faults.

Precise lubrication management

Add designated lubricating oil/grease to key moving parts such as gears, chains, guide rails, and bearings according to the equipment manual cycle, record the lubrication time and amount, and avoid excessive or insufficient lubrication.

Check the oil level and pressure of the automatic lubrication system to ensure continuous and effective oil supply.

2、 Systematic Regular Maintenance

Mechanical component inspection and calibration

Printing unit: Calibrate the roundness of the printing plate cylinder, adjust the angle and pressure of the ink scraper (recommended angle 50 ° -65 °), and regularly replace worn rubber blankets and scrapers.

Pressure system: Test the uniformity of printing pressure every week, adjust the drum gap according to the thickness of the paper, and avoid uneven pressure causing local wear or blurry printing.

Transmission system: Check the tension of the conveyor belt, chain wear, and gear meshing status, and replace deformed/worn parts in a timely manner.

Electrical system maintenance

Regularly clean the dust in the electrical cabinet, check for aging circuits and loose terminals, and replace damaged components (such as contactors and relays).

Verify the reliability of carton flexo printer die cutter slotter machine grounding to prevent static interference or electric shock risks.

3、 Fault Prevention and Rapid Handling

Uneven ink color: deviation in the angle of the ink scraper and uneven roundness of the roller. Solution: Correct the drum, adjust the scraper to 55 °± 5 °, and test the pressure.

Periodic blocking: Insufficient ink solvent and rapid drying. Solution: Increase the solvent ratio and switch to slow drying ink.

Edge burrs on printed materials: substrate static electricity, insufficient ink polarity. Solution: Add anti-static agents or polar solvents.

Abnormal vibration during corrugated carton printing slotting die cutting machine operation: loose drive belt, worn bearings. Solution: Tighten the positioning screw and replace the bearing.

4、 Key safeguard measures

Environment and energy adaptation: Install a regulated power supply, regularly check the circuit connections, and avoid voltage fluctuations that may cause shutdown (such as instantaneous voltage drop>10%). Control workshop temperature and humidity (recommended 22-26 ℃, humidity 50% -60%) to reduce paper deformation and static electricity accumulation.

Intelligent system maintenance: Regularly backup CNC parameters (such as servo gain and position feedforward values), verify the accuracy of the registration system, and adjust the drum phase using standard calibration tools. Upgrade the temperature control system (such as integrating Bricort coating temperature control) to ensure stable ink viscosity (error ≤± 0.5 ℃).

Personnel operation standards

Operator training: covering equipment start stop process, emergency braking operation, daily inspection checklist (such as checking the sealing of ink pump before starting).

Develop a preventive maintenance plan: specify daily/weekly/monthly maintenance items (such as monthly testing of vacuum pump muffler efficiency).

5、 Sustainable operation strategy

Spare parts management: Establish a list of vulnerable parts (rubber blanket, sealing ring, paper feeding belt), reserve them in advance according to their service life, and avoid downtime and waiting for materials.

Noise control: Install factory boundary sound barriers (noise reduction ≥ 20dB) and equipment soundproof rooms that meet environmental standards (factory boundary noise ≤ 65dB).

Through the multi-dimensional management mentioned above, the failure rate can be significantly reduced (such as reducing the frequency of paper jams by more than 80%), extending equipment life by more than 30%, and ensuring a printing pass rate of more than 98%.
