LXG-2/20 Auto Bottle Blowing Machine Feature
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, no elongations, low maintenance cost
●Self-lubricate bushing and sealed bearing
●Different chain pitch to optimize production based on specific neck finish diameters
●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.
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. No turbulence
●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
3 Preform Transfer & Pitch Change
●Servo-driven pitch-change system to optimize heating efficiency (oven pitch) and maximum bottle diameter (blowing pitch)
●Simple, solid 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)
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
5 Bottle Ejection
●Servo-driven unit for bottle discharge
●Discharge on air conveyor or belt conveyor or vacuum conveyor
●Bottle base cooling option
