Just like a car, a powder filling machine requires regular maintenance. This not only prevents breakdowns and safeguards production but also extends the equipment's service life, maximizing its value. Based on over 20 years of industry experience, DJ-Pack has outlined 7 key maintenance points for you. No matter which model you use, following these can make your equipment run more stably and last longer.
Point 1: Deep Cleaning and Lubrication Check
After completely disconnecting power and air supply, thoroughly disassemble and clean the auger, hopper, discharge port, and all parts that come into contact with the powder material. Check the filters and pipelines of the dust extraction system to ensure suction is unobstructed. Replenish food-grade lubricating oil or grease at all designated lubrication points. Deep cleaning and lubrication reduce cross-contamination from material residue, prevent accuracy drift, and avoid equipment jams. Our DJ-Pack machines feature a quick-disassembly design, making cleaning very convenient.
Point 2: Weighing System Calibration and Check
Use standard calibration weights to recalibrate the machine's weighing system. Check the load cells and connecting cables for any physical damage, moisture, or corrosion. Clean the weighing platform to ensure there is no interference. This ensures filling accuracy, reduces product filling errors, and minimizes material loss during production. DJ-Pack uses internationally renowned high-precision load cells, known for their stability and strong anti-interference capability, and we provide calibration procedure guidance.
Point 3: Pneumatic and Vacuum System Inspection
Check the air filter, pressure regulator, and lubricator; drain any accumulated water to ensure stable air pressure and clean air supply. Listen for air leaks or sluggish movement in cylinders and solenoid valves. Clean the filter unit of the vacuum generator. Unclean or unstable air supply can cause jerky movements in the filling equipment, affecting operational efficiency.
Point 4: Electrical and Control System Diagnostics
Check all wiring connections are tight, and look for signs of looseness or overheating. Clean the cooling fans and filters of electrical components like the PLC and servo drives. Back up the machine's parameter and recipe data. Loose wiring connections are a common yet difficult-to-troubleshoot fault. Proper heat dissipation extends the service life of core electrical components like servo systems and PLCs. DJ-Pack uses branded components from Siemens, Schneider, and others, and provides clear electrical diagrams to give your inspections a solid basis.
Point 5: Mechanical Structure Tightening and Alignment Check
Inspect and tighten all critical fasteners on the machine. Check wear on transmission parts like timing belts and replace if necessary. Verify that the discharge port is correctly aligned with the product center position. Long-term operation can cause parts to loosen, and belt wear can also affect filling accuracy.
Point 6: Wear Parts and Consumables Replacement
Evaluate and replace wear parts like sealing rings and dust extraction filters. Check the touchscreen for responsiveness. Timely replacement of wear parts can prevent unexpected downtime during peak seasons and avoid issues like filling accuracy drift. DJ-Pack can provide customers with genuine wear part kits to ensure the machine performs like new.
Point 7: Operational Test and Performance Review
After completing the above maintenance steps, conduct no-load and load operation tests. Perform filling accuracy tests with your product to verify the maintenance results.
DJ-Pack recommends performing this maintenance during production off-peak seasons or before holidays, especially for equipment running under high load.
