PET Bottled Water Blowing Filling Capping Combiblock

High speed PET bottled water blowing/filling/capping combiblock is widely used for bottling mineral water and pure water.

3-in-1 combiblock is innovated and designed in the requirement of still pure water and mineral water, on the bases of introducing, digesting and absorbing advanced technology from abroad. The combiblock avoids friction of bottles during air conveying and helps reducing bottle weight to reduce cost.

Main Features

1. Blow Molding Machine

a) Machine operation adopts TFT touch screen with multi languages and friendly interface. Speed, shift capacity and technical specifications can be set on the menu.

b) High efficiency: 2,500 BPH/cavity (500ml water bottle)， servo stretch system.

c) Double blowing system. Monitoring pressure change curve of each cavity during bottle forming and providing accurate timely parameters, easier for operator to regulate technical parameters and ensure quality stability.

d) Adopt cam organism and accurate mechanical arm transferring technology with high speed preform and bottle feeding, avoiding contamination.

e) Cam organism controls mold opening and clamping precisely with special mold clamping boost system and firm mold shelf structure; independent control of blowing parameters of each cavity; malfunction diagnosing function; enhanced neck sealing stability; regulating blowing pressure; stretching bar controls accurate preform axial stretching and 1^st / 2^nd blowing controls vertical stretching; regulating of 1^st / 2^nd blowing precisely ensures ideal distribution of bottle wall thickness.

f) Heating adopts 10-section far infrared temperature control; each heating lamp of pre-heating and regulating zone can be regulated; timely temperature monitoring system ensures technical stability and accuracy, avoiding over high temperature of outer preform wall; 10-20% electrical power is saved by this heating system.

g) Air recycling system (optional) may save compressed air by 30-50%.

h) Technical parameters like heating temperature and blowing time can be set according to different preforms and bottle design.

i) Fast mold changing (within 2 hours) reduces stop time and increases production efficiency.

j) Humanized design makes complicated industrial operation get used to habits.

k) Blowing mold is made of aluminum alloy with oxidization treatment on surface to prolong mold lifespan.

l) Preform infeed starwheel adopts preform block detecting device. When blocks, preform will be rejected and reset automatically.

m) Safety door is equipped with alarming device to protect operators.

Transfer starwheel

a) Neck holding by s/s starwheel. No need to adjust machine height when changing different bottle size.

b) Bottle bottom holding transferring method for bottle outfeed by downward spiral curve.

c) Equipped with bottle jam protection device.

Filler

a) Made of stainless steel.

b) Large flat bearing with teeth, stable and reliable performance.

c) Gravity filling.

d) Ring shape tank with float ball level control.

e) High speed and high accuracy filling valve with 200ml/s flowing speed

f) Filling valve equips dummy cup and can do CIP circularly.

g) With rotary spray ball in tank to ensure cleaning effect.

h) Lift by pneumatic cylinders.

Capper

a) Magnetic constant torque capping head ensures stability and controls defective rate of capping less than 0.2%.

b) Cap dropping rail equips a group of photoelectrical switch for reverse cap detecting. When lack of cap, machine will be stopped automatically.

c) Bottle infeed detecting switch works with the pneumatic cylinder on cap starwheel to avoid feeding cap on no-bottle condition.

1. Bottle Outfeed Conveyor

a) Conveyor motor uses frequency control of motor speed, which keep pace with the combiblock, preventing overturned bottle.

b) Bottle outfeed conveyor equips photoelectrical switch. When bottle blocks, the speed of combiblock will be slowed down and stop.

2. Stand

a) The table is a little bit inclined to avoid water accumulation.

b) Good drainage pipes.

3. Electronic Control

The electronic components like PLC and transducer are from Mitsubishi, Omron, etc., The pneumatic devices are also from international famous brand.
