The maintenance of filling machines mainly includes daily maintenance and regular maintenance. The specific measures are as follows:
Daily maintenance:
Check components: Check whether each component is normal before each use, whether there is looseness, leakage, etc.
Clean equipment: Clean the dust and stains on the material contact parts and the surface of the equipment. Clean the residual materials in time after use to prevent dry corrosion. Wipe the machine body with a damp cloth and apply anti-rust oil to the rust-prone parts.
Clean pipes: Keep the liquid filling machine pipes clean, especially the parts in contact with the materials. Brush the pipes every week, run water every day, and sterilize each time to ensure that the filling machine is clean and free of scale.
Check pneumatic components: Check whether the pneumatic pipeline has leaks, whether the air pipe is broken, and keep the surface of the machine and the electric control cabinet clean.
Observe mechanical parts: During the production process, regularly check the rotating and lifting parts of the equipment to ensure that there are no abnormalities and the screws are tightened.
Regular maintenance:
Check the transmission parts: Check the wear of transmission parts such as chains, gears, and belts at regular intervals, and adjust or replace them if necessary.
Replenish lubricating oil: Replenish lubricating oil to lubrication points such as bearings and gears, check the sealing and operation of pneumatic components, and clean impurities in filters.
Calibrate the metering device: Calibrate the metering device regularly to ensure accuracy according to the frequency and condition of use.
Replace lubricating oil: Replace the lubricating oil (grease) of the reducer motor every year, check the tightness of the chain, and adjust the tension in time.
Sensor protection: The sensor is a high-precision, high-sealing, and high-sensitivity device. It is strictly prohibited to impact and overload, and it is not allowed to be disassembled unless it is necessary for maintenance.
Common troubleshooting methods:
Inaccurate filling volume: It may be due to wear of the metering pump seal or change in material viscosity or pipeline blockage. It is necessary to replace the seal, adjust the parameters, or clean the pipeline.
No material discharge: Check whether the material supply system and pipeline valves are open, and clean the blocked filling head.
Unstable equipment operation: The equipment may be installed unstably, the transmission components may be faulty, or the bearings may be damaged, which may require reinstallation, repair, or replacement of components. Electrical system failure requires checking the circuits and replacing damaged electrical components.
