How often does the packing machine need maintenance, and what should be checked?

It is recommended to carry out a routine maintenance inspection after every one month of continuous operation to ensure stable performance, long service life, and safe running of the packing machine. Regular maintenance can effectively prevent unexpected breakdowns, reduce downtime, and maintain consistent packaging quality.

During the monthly inspection, the following items should be carefully checked:

Fasteners and Mechanical Structure

Check whether all screws, bolts, and nuts on each part of the machine are loose due to vibration during operation. Pay special attention to the frame, sealing jaws, forming parts, conveyor, and moving mechanisms. Tighten any loose fasteners to prevent misalignment, abnormal noise, or mechanical failure.

Suction Cups (Vacuum System)

Inspect the suction cups for wear, cracks, deformation, or loss of elasticity. Aging or damaged suction cups may cause unstable bag picking or positioning, leading to production errors or stoppages. Replace them if vacuum holding force becomes weak.

Air Hoses and Pneumatic Lines

Check all air hoses for aging, hardening, cracks, or air leakage. Make sure the connections are firm and there is no pressure loss, which could affect the stability and speed of pneumatic movements.

Air Regulators and Filters

Inspect the air regulators to confirm that the pressure settings are correct and stable. Drain water and impurities from the air filter regularly to prevent moisture and dust from entering pneumatic components, which could cause corrosion or malfunction.

Cylinders

Check the cylinders for smooth movement, air leakage, abnormal noise, or oil leakage. Ensure that the piston rods are clean and properly lubricated, and that there is no wear on seals that could reduce working efficiency.

Solenoid Valves

Inspect the solenoid valves for normal switching action and stable response. Check wiring connections and ensure there is no overheating, sticking, or air leakage. Faulty solenoid valves may lead to incorrect timing or loss of control in the pneumatic system.

General Cleaning and Lubrication

Clean dust, powder, or product residue from the machine surface and moving parts. Apply suitable lubricating oil or grease to designated lubrication points according to the machine manual, ensuring smooth operation and reduced wear.

By performing these checks every month, potential problems can be detected early, component life can be extended, and the packing machine can continue to operate efficiently, safely, and reliably over the long term.
