LXG-8 700ml/2L Auto PET bottle blow molding machine
Product Description
LXG- 8 Auto Bottle Blowing Machine Feature
1.1 Preform Feeding & Handling system
- Continuous preform feeding system
- Proper preform stabilization time on star-wheel before spindle insertion
- Composite aluminum alloy chain: strong, no wear, low maintenance cost
- Self-lubricate bushing and sealed bearing
- Ejection system for oval or not well inserted preforms
- Quick-change system (option) in less than 5 minutes for different neck diameters: change of loading wheel and loading guides
1.2 Preform Heating System
- Perfect heating system design helps decrease the power consumption.
- Special oven design helps power saving and is easy maintain.
- Preform heating system with laminar flow.
- Low thermal inertia: higher heating process consistency and fast start-up
- Oven dimensions based on preform and max bottle size (from 8 to 16 lamps)
- Modular oven
- Adjustable position for neck change
1.3 Preform Transfer & Pitch Change
- Servo-driven pitch-change system to optimize heating efficiency (oven pitch) and maximum bottle diameter (blowing pitch)
- Simple and reliable system
- Servo-driven unit for same-time preform and bottle transfer
- Precise and gentle preform holding
- Very high transfer speed
- Quick change of personalized parts (tool-less)
1.4 Stretching & Blowing
- Electrically driven blowing clamp, no oil
- Servo-driven motion with levers and oscillator
- High clamp speed
- Double-sided pneumatic compensation
- Servo driven stretch rods
- Fine setting of stretch profile thanks to servo control
- Blow seals, fast and independent for every cavity
- Self-learning of stretch stroke based on preform-bottle size
- High tech blowing valves: fast and independent for every cavity, with individual pre-blow flow regulation
- Very quick exhaust
- Standard Air tanks for peak blowing ramp, providing higher output
- By-pass valve to avoid chilled water when not in production
- Less power consumption once machine is in idle mode or is waiting for downstream
- No condensation on blow moulds once the machine is not blowing bottles
1.5 Bottle Ejection
- Servo-driven unit for bottle discharge
- Discharge on air conveyor or belt conveyor or vacuum conveyor
- Bottle base cooling option
