Solutions to Unstable Filling Volume on a Filling and Sealing Machine

The issue of unstable filling volume on a filling and sealing machine can significantly impact product quality and production efficiency. To address this issue, the following solutions can be implemented:

I. Check Equipment Connections and Seal Integrity

1. Inspect Hose Connections:

• Ensure that there are no leaks at the connections between the feed hose and the filling machine. If bubbles or drips are observed, tighten the connections using a wire or wire pliers until there are no leaks.

2. Check Seals:

• Inspect the O-rings in the cylinders for signs of aging or damage, and replace them promptly if necessary. Additionally, examine the seals on the filling pump and three-way valve to ensure they are intact, as damaged seals can lead to unstable filling volumes.

II. Clean and Inspect Critical Components

1. Clean Copper Check Valves:

• Regularly inspect and clean the interior of the copper check valves to remove any dirt or particles that may cause clogging. Clogged valves can affect the proper opening and closing of the valves, resulting in unstable filling volumes.

2. Inspect Filling Valves:

• Check the filling valves for any material blockages, especially residual materials that have not been cleaned for an extended period. If blockages are found, clean them promptly to ensure smooth material flow.

III. Adjust Equipment Parameters and Settings

1. Adjust Flow Meters:

• If the machine uses flow meters to control filling volumes, verify that the flow meters are functioning correctly. Adjust or recalibrate the flow meters as necessary to ensure accuracy.

2. Adjust Filling Speed:

• Too fast or too slow filling speeds can both lead to unstable filling volumes. Try adjusting the filling speed throttle valve to find the optimal filling speed.

3. Check Air Pressure:

• The filling and sealing machine requires stable air pressure to ensure accurate filling volumes. Check the air supply pressure for stability and adjust it to the appropriate range (e.g., 0.4~0.5 MPa).

IV. Inspect and Replace Wear Parts

1. Inspect Filling Nozzle Valve Cores:

• Stuck or delayed opening of filling nozzle valve cores can contribute to unstable filling volumes. Check the valve cores for smooth operation, and address any sticking issues promptly.

2. Check Cylinder Piston Rods:

• Prolonged use can cause cylinder piston rods to deform or wear, leading to unstable filling volumes. Regularly inspect the piston rods for signs of deformation or wear, and replace them as needed.

V. Additional Considerations

1. Equipment Stability:

• Ensure that the filling and sealing machine is placed on a stable surface, with the four base screws tightened securely, to prevent shaking during operation.

2. Regular Maintenance:

• Perform regular maintenance on the filling and sealing machine, including cleaning, lubrication, and tightening, to extend its lifespan and reduce the occurrence of faults.

3. Proper Operation:

• Operators should strictly follow the operating procedures of the machine to avoid improper operation that could damage the equipment or cause unstable filling volumes.

By implementing these solutions, the issue of unstable filling volume on a filling and sealing machine can be effectively addressed, improving product quality and production efficiency.
