To ensure stable and uninterrupted operation of the paper cup and bowl forming machine, all operators must master operating procedures and the full paper container forming process.
The equipment adopts integrated transmission and precision mechanical parts, each undertaking independent and critical production functions. Operators shall read the official manual thoroughly to grasp the machine structure, transmission principles and overall performance.
⚠️ Important Notice Daily maintenance mainly includes regular cleaning and lubrication. Standard daily upkeep stabilizes operation, reduces failure rate, and extends the service life of the whole machine and wearing parts.
Chapter 2 Standard Periodic Maintenance Rules
Standard regular maintenance optimizes equipment operating conditions, keeps the machine in optimal status, and prolongs its service life. Details are as follows:
2.1 Daily Inspection & Lubrication
Inspect the whole machine before startup and after shutdown daily. Check all hinge joints and reciprocating moving parts on the frame, and fill with qualified grease per industrial standards.
2.2 Cylindrical Pin & Circlip Inspection and Replacement
Check the tightness of cylindrical pins at all connection points and confirm circlips are installed firmly without loosening or shifting.
⚠️ Operation Prohibition Replace deformed, displaced or elastic-fatigued circlips immediately with new ones of the same specification. It is strictly forbidden to run the machine with defective parts.
2.3 Fastener Inspection & Tightening
Check all bolts, nuts and fasteners on the equipment. Tighten any loose parts in a timely manner.
⚠️ Safety Warning
Loose fasteners may cause mechanical resonance and component displacement, and even lead to mechanism jamming and severe mechanical damage.
2.4 Abnormity Emergency Handling
Operators and maintenance staff shall monitor abnormal noise, vibration and mechanical offset during continuous production.
⚠️ Operation Specification
Stop the machine and cut off power immediately once any abnormity occurs. Inspection and maintenance can only be carried out after a complete stop. Do not resume production until all faults are fully removed.
2.5 Maintenance Qualification Requirement
Equipment disassembly, overhaul and key part replacement must be performed by professional qualified personnel. Non-professionals are not allowed to disassemble or adjust the machine arbitrarily to avoid personal injury and precision component damage.
2.6 Lubrication Oil Pump Filter Maintenance
Clean paper dust, oil sludge and impurities from the oil pump filter regularly to prevent oil circuit blockage, poor lubrication and dry friction wear.
New machine running-in period (first 2 months): Clean once a week
Normal production period: Clean every two weeks
Keep oil circulation smooth and lubrication pressure stable at all times.
2.7 Lubricant Replacement Cycle
New machine first oil change: After 30 consecutive working days
Regular replacement thereafter: Every 6–12 months, subject to oil cleanliness and actual load
Clean sediment and impurities at the tank bottom during each oil change.
2.8 Optical Sensor Maintenance
Optical sensors are easily affected by paper dust and moisture and need regular cleaning. Maintenance Cycle: Clean every 3–5 working days
Keep high detection sensitivity and positioning accuracy to avoid false detection, feeding errors and accidental shutdown alarms.
2.9 Blower Inlet Filter Maintenance
The blower filter easily accumulates paper lint and dust, and shall be cleaned weekly. Ensure sufficient air flow and stable pressure to meet the technical requirements of air blowing and negative pressure adsorption for cup forming.
