How To Operate The Full Automatic Bottle Blowing Machine

How to operate the semi automatic bottle blowing machine

  1. Safety Precautions Personal Protective Equipment (PPE): Operators must wear safety glasses, gloves, and closed-toe shoes to prevent injuries from moving parts or hot surfaces. Emergency Stop: Familiarize yourself with the emergency stop button location. Press it immediately in case of abnormalities. Lockout/Tagout (LOTO): Follow LOTO procedures during maintenance to prevent accidental startup. High Temperature Warning: Avoid contact with heated components (e.g., molds, nozzles) to prevent burns.
  1. Pre-Operation Checks Power & Air Supply: Ensure stable power (voltage as specified) and compressed air (typically 6–8 bar) are connected. Lubrication: Verify oil levels in hydraulic/pneumatic systems and refill if necessary. Mold Inspection: Check molds for damage, cleanliness, and proper alignment. Material (Preforms/PET): Ensure preforms meet specifications (dry, uncontaminated) and are correctly loaded into the hopper.
  1. Startup Procedure Power On: Switch on the main control panel and activate the machine. Heating: Preheat molds and blow nozzles to the set temperature (typically 100–120°C for PET). Allow sufficient warm-up time. Test Run: Run in manual mode to check ejection, clamping, and air pressure. Inspect initial bottles for defects (uneven thickness, bubbles). Auto Mode: Once stable, switch to automatic production.
  1. Operation Monitoring Parameters: Continuously monitor temperature, pressure, and cycle time via the HMI (Human-Machine Interface). Quality Control: Randomly check bottle weight, wall thickness, and neck finish dimensions. Material Feed: Ensure consistent preform supply to avoid jams.
  1. Shutdown Procedure Stop Production: Switch to manual mode and clear remaining preforms. Cool Down: Allow molds and heaters to cool below 60°C before shutdown. Clean Machine: Remove residual plastic and lubricate moving parts. Power Off: Turn off main power and air supply.
  1. Troubleshooting Common Issues Bottle Defects: Adjust air pressure, temperature, or mold alignment if bottles are deformed. Jamming: Clear blockages in the conveyor or hopper using tools (never hands). Leaks: Check pneumatic lines and seals for air leaks.
  1. Maintenance Daily: Clean molds, inspect sensors, and check air filters. Weekly: Lubricate chains and bearings; calibrate temperature sensors. Monthly: Replace worn-out seals and inspect electrical wiring.
  1. Warning Labels & Compliance Follow ISO 9001/CE standards for machinery safety. Display hazard warnings (e.g., “High Voltage,” “Hot Surface”) visibly on the machine.
