Before diving into maintenance details, it is essential to review the core technical parameters of this 3-in-1 monoblock machine. Designed specifically for pure water, mineral water, and juice, the CGF12-12-6 adopts advanced micro-negative pressure filling technology, offering more efficient and stable filling with higher output compared to (same-tier) equipment.

Equipped with 12 rinsing heads, 12 filling heads, and 6 capping heads, the machine boasts a standard capacity of up to 4,000 bottles per hour (for 500ml PET bottles). The entire system utilizes a Siemens PLC automatic control system and photo-electronic detection technology, paired with a Mitsubishi frequency converter, achieving seamless automation from air-channel bottle loading to capping and discharging.

Core System Maintenance and Adjustment Guide for the CGF12-12-6

To ensure long-term stable operation, equipment engineers must strictly adhere to the following maintenance and adjustment protocols for the core systems:

1. Break-in and Speed Control for the Driving System

The driving system is the heart of the filling machine, comprising the main motor (3kW), belt system, worm reducer, and gear assemblies.

• New Machine Break-in Maintenance: For newly installed CGF12-12-6 equipment, during the first 10 days of operation, the running speed should be set at approximately 80% of the rated speed to ensure thorough break-in of gears and transmission components.
• Speed Control: During daily production, speed can be adjusted via the touch screen, but the maximum running speed must strictly not exceed 120% of the rated value to prevent excessive mechanical wear.

2. Air Channel Calibration for the Bottle-Loading System

This equipment features a new damage-free air channel loading design. Precise adjustment of the air channel gap is crucial to prevent bottle jamming and reduce frequent system start-stops.

• Gap Adjustment Standard: The gap between the air channel rails should be approximately 1mm wider than the diameter of the PET bottle neck.
• Adjustment Steps: Loosen the fixing bolts below the air channel -> Adjust the stainless steel slats to the required width -> Ensure the gap width is consistent along the entire channel -> Tighten the bolts.
• Anti-Jamming Maintenance: Regularly inspect the block device to ensure the air cylinder responds sensitively, allowing only a consecutive single line of bottles to pass through, preventing scattered bottles from triggering system failures.

3. Hydraulic and Seal Checks for the Rinsing & Filling Systems

• Rinsing Water Pressure Monitoring: Daily inspections must ensure that the rinsing water pressure is maintained between 0.06 MPa < P ≤ 0.2 MPa. Low pressure leads to inadequate rinsing, while high pressure may damage the water distribution valve seals.
• Handing-over System Maintenance: The transfer from rinsing to filling, and filling to capping, utilizes the clamping-bottle-neck method. When switching to bottles of different shapes or heights (applicable height: 160mm-320mm), only a few parts like stars and guides need replacement. After adjustment, manually turn the machine to check for smooth transfer.

4. Capping and Cap-Unscrambling Systems

• Cap Tray and Outlet Slot: Regularly check the smoothness of the cap-unscrambler and cap-outlet slot. Clear any plastic debris from the slots to prevent cap jamming.
• Capping Head Adjustment: Precisely adjust the height and torque of the capping heads according to the cap type and bottle height to ensure sealing integrity without damaging the caps.

Daily Care and Troubleshooting Recommendations

Based on the maintenance standards in the operational manual, beverage plants are advised to establish the following three-tier maintenance system:

1. Daily Maintenance:
   • Clean the surfaces of photo-electronic detectors to ensure blind-spot-free signal detection.
   • Check for abnormal noises or looseness in transfer stars and dial wheels.
   • Clear dust and debris from the cap-unscrambler and air channel.
2. Regular Lubrication:
   • Strictly follow the equipment lubrication chart to regularly apply food-grade lubricating oil/grease to the worm reducer, main drive gears, cams, and bearings.
3. Electrical System Troubleshooting:
   • Regularly check the wiring terminals in the Siemens PLC control cabinet for looseness.
   • Inspect the cooling fans of the Mitsubishi frequency converter to ensure proper temperature inside the control cabinet, preventing the aging of electronic components.

Conclusion: Scientific Maintenance Empowers Efficient Production

With its high level of automation and excellent bottle adaptability (applicable bottle diameter: Φ50mm—Φ115mm), the CGF12-12-6 Monoblock Rinsing, Filling, and Capping Machine has become the ideal choice for small to medium-sized beverage enterprises. However, even the most advanced PET bottle filling equipment requires scientific maintenance. Strictly implementing the maintenance standards outlined above will not only significantly reduce equipment failure rates but also effectively extend the machine's lifespan, creating greater commercial value for your business.
