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
