When a capping machine is not used for an extended period (such as during production stoppages or seasonal shutdowns), proper storage and maintenance can prevent parts from rusting and aging, ensuring stable performance upon reuse. The process should follow a three-step procedure: "Clean - Protect - Store." The first step is thorough cleaning. First, remove any remaining bottle caps and bottle fragments from the equipment. Dilute a neutral detergent and wipe the machine body, capping molds, and conveyor belt (if applicable) with a soft cloth. Pay special attention to cleaning the gaps inside the molds, the motor surface, and the air source interface (for pneumatic machines) to remove oil and dust. After cleaning, rinse the cloth with clean water and wipe the equipment a second time to ensure no detergent residue remains. Finally, dry the surface and internal parts of the equipment with a dry cloth, especially ensuring that metal parts (such as molds and gears) are completely dry to prevent moisture and corrosion. The second step is component protection. Apply food-grade rust-preventive oil to metal moving parts (such as capping heads, transmission gears, and bearings), covering them with a thin layer to avoid excessive oil dripping. For pneumatic capping machines, the air source must be turned off, the air pipes disassembled and the internal residual compressed air cleaned, and dust caps should be placed on the air pipe interfaces. For electric capping machines, the power plug must be unplugged, and the metal parts of the plug wrapped with insulating tape to prevent oxidation. Capping molds must be disassembled separately, cleaned, and placed in a special packaging box lined with soft cloth to prevent collision and wear. The third step is proper storage. Choose a dry, well-ventilated, and dark indoor environment for storage, avoiding areas with dampness (such as basements), high temperatures (such as near heating), or corrosive gases (such as chemical warehouses). The equipment should be placed on a flat surface, with a wooden pallet underneath to prevent moisture damage. If the equipment is large, it can be completely covered with a dust cover to reduce dust accumulation. During storage, it should be inspected monthly to check for rust on metal parts and aging on plastic parts. If the anti-rust oil is found to have dried out, it needs to be reapplied. Electrical components should be powered on periodically (such as for 10 minutes every 2 months) to prevent capacitor aging and ensure normal startup when used again.
