The automatic die-cutting machine, as a high-precision production equipment, its stability and service life are directly related to the production efficiency and cost control of the enterprise. Scientific maintenance can not only reduce the downtime loss but also avoid potential safety hazards. The following is a systematic maintenance plan covering daily maintenance, periodic inspection, and fault prediction, which will help you maximize the equipment efficiency.

I. Daily Operation Specifications: Details Determine the Equipment Life
Cleaning and Lubrication
After daily operation: Clean the residual adhesive stains and paper scraps on the die-cutting platform (using non-woven fabric + special cleaning agent) to prevent debris from getting stuck in the transmission components.
Key Lubrication Points: Add food-grade lubricating grease (recommended ISO VG32 standard) to the guide rails, bearings, and gear sets in each shift to avoid dry friction damage.
Die Management
Inspection before use: Confirm that there are no chipping or rust on the cutting edge. When installing, evenly tighten the screws to prevent uneven cutting marks caused by uneven pressure.
Storage Specification: Hang the die vertically or place it flat on a moisture-proof rack to avoid deformation due to stacking.
Operation Monitoring
Abnormal Sound Warning: In case of sudden metal friction sound or increased vibration, stop the machine immediately and check the tightness of the transmission belt or the status of the bearings.
Pressure Calibration: Use a pressure tester to check the die-cutting pressure every week. If the error exceeds ±5%, the hydraulic system needs to be adjusted.

II. Periodic In-depth Maintenance: Execute According to the Schedule for Precise Operation and Maintenance
Period Maintenance Items Operation Standards
Monthly Servo Motor Heat Dissipation Inspection Clean the dust on the fan and detect that the insulation resistance of the winding is ≥100MΩ
Quarterly Pneumatic System Maintenance Replace the filter element and detect that the response time of the solenoid valve is ≤0.1s
Half-yearly Transmission System Calibration Use a laser interferometer to adjust the parallelism of the lead screw, with an error of ≤0.02mm/m
Annually Overall Equipment Accuracy Re-inspection Pass the ISO 9001 standard template test, and the cutting accuracy meets the standard of ±0.1mm

III. Self-check and Troubleshooting Guide for Common Faults
Scenario 1: Incomplete Die-cutting / Burring
Possible Reasons: Die wear, insufficient pressure, aging of the bottom roller
Solutions: Replace the die gasket (0.3-0.5mm kraft paper), increase the pressure value by 5%-10%
Scenario 2: Feeding Offset / Paper Jam
Possible Reasons: Contamination of the deviation correction sensor, slipping of the feeding roller
Quick Treatment: Wipe the sensor lens with alcohol, and check the wear condition of the silicone layer on the roller surface (replace if the depth of the dent is > 0.02mm)

IV. Intelligent Maintenance Upgrade: Reducing Dependence on Manual Labor
Internet of Things Pre-maintenance System: Through the vibration sensor + cloud data analysis, it can give an early warning of the bearing life and the risk of belt aging 7 days in advance.
AR Remote Assistance: Scan the equipment QR code to call the 3D maintenance manual, and the engineer can remotely guide the replacement of complex components.

V. Long-term Maintenance Strategy: Investment Return Doubling Plan
Spare Parts Inventory Optimization
Key Spare Parts List: Servo drive, high-precision guide rail, infrared detection module (the stock quantity is ≥ 1.5 times the safety stock)
Personnel Training System
Certification Mechanism: Operators need to pass the "Equipment Maintenance L1-L3" level assessment, and the annual retraining is ≥ 8 hours.
Maintenance Cost VS Fault Loss: Calculate This Account
Annual average cost of regular maintenance: Approximately 2%-3% of the equipment value
Direct loss of sudden faults: Single downtime ≥ 5 hours, and the lost production capacity + emergency repair cost can reach 10 times the maintenance cost!
