Packaging machines are critical equipment in modern production lines, widely used in food, pharmaceutical, daily chemicals, and other industries. Standardized operation and scientific maintenance not only enhance efficiency but also prevent safety incidents and equipment wear. Below are seven essential precautions to ensure stable operation of packaging machines:

‌1. Pre-Operation Preparations‌

1. ‌Equipment Inspection‌

   • Verify intact power cords and air supply pipelines, and ensure emergency stop buttons function properly before startup.
   • Check key components (conveyor belts, cutting blades, heat-sealing mechanisms) for cleanliness and foreign object removal.
   • Confirm packaging materials (e.g., film rolls, labels) match the machine’s technical specifications.

2. ‌Environmental Checks‌

   • Ensure the operating area is dry, well-ventilated, and free from high temperature/humidity to prevent electrical component failures.
   • Clear debris from work surfaces to avoid foreign objects falling into the machine and causing jams.

‌2. Safe Operation Protocols‌

1. ‌Personal Protection‌

   • Operators must wear protective gloves and safety goggles to avoid contact with high-temperature parts or sharp blades.
   • Secure long hair and avoid loose clothing to prevent entanglement in mechanical components.

2. ‌Prohibited Actions During Operation‌

   • Never reach into protective covers to adjust materials or clean debris while the machine is running.
   • Avoid overloading the machine beyond its designed capacity (e.g., weight or size limits).

‌3. Parameter Setting and Calibration‌

1. ‌Precision Parameter Adjustment‌

   • Adjust heat-sealing temperature, pressure, and duration based on packaging material type (e.g., plastic film, aluminum foil) to prevent weak seals or burn-through.
   • Regularly calibrate sensors for dynamic weighing models to ensure measurement accuracy.

2. ‌Test Run Verification‌

   • Conduct a low-speed test run when using new packaging materials to check seal quality and material alignment.
   • Fine-tune photoelectric sensors to ensure accurate label/pattern positioning.

‌4. Daily Maintenance and Servicing‌

1. ‌Cleaning and Lubrication‌

   • Clean residual materials and dust daily, especially gears, rails, and other critical areas.
   • Apply specialized lubricants as specified in the manual to minimize component wear.

2. ‌Replacement of Wear-Prone Parts‌

   • Track usage duration of blades, sealing strips, and conveyor belts; replace aging parts promptly.
   • Store spare parts properly to avoid moisture damage or deformation.

‌5. Troubleshooting and Emergency Measures‌

1. ‌Common Issue Diagnosis‌

   • ‌Poor Sealing:‌ Verify temperature accuracy, pressure uniformity, or replace worn heat-sealing strips.
   • ‌Material Jams:‌ Press the emergency stop button immediately and manually reverse the drive shaft to remove obstructions.

2. ‌Avoid Unauthorized Repairs‌

   • Leave electrical faults or software errors to certified technicians; never disassemble circuit boards without authorization.

‌6. Long-Term Shutdown Precautions‌

• For shutdowns exceeding one week: disconnect power, release residual air pressure from pumps.
• Apply anti-rust oil to metal components and cover the machine with a dust-proof sheet.

‌7. Staff Training and Record Management‌

• Operators must undergo systematic training on the machine manual and emergency protocols.
• Maintain maintenance logs to document daily operations, malfunctions, and repair history.
