There are six infrared heating tubes adopting the best heating
technic with bottleneck underneath. It reduces heat going upwards
which damages bottleneck.
At the heating area, there are finely designed air flow technics,
cooling water tunnel for bottle neck, and air cooling protection
device, which provide thorough protection to bottle neck.
Heating tube temperature and preform temperature are transferred to
PLC through oven temperature sensor and infrared thermodetector,
and the actual temperature can be displayed and set at computer
screen. By using PID function, each layer of heating tube power can
be adjusted in order to achieve the best heating temperature curve
for the preform.
The new designed modular heating oven adopted structural advantages
from different overseas manufacturers, and installed specially
designed extra-long short wave infrared heating tube for the
optimization of spectral wavelength and reflectance coating. It
increased reflection efficiency, and heating oven becomes more
energy-saving, also more convenient for installation and
maintenance.
Optimizing and adjusting air flow of the heating area increases
heating stability. Moreover, the unique three-way air tunnel cools
the preform body, bottle neck and preform holder with different
amount of cooling air, which effectively protects bottle neck
damages.
Blowing unit
Special manipulator delivers heated preforms to moulds along
certain cam curve. After stretch pre-blow, the preform will be
blown to bottles by connecting high pressure compressed air.
Special manipulator sends the finished bottle out along certain cam
curve.
Filling unit
The blow-made bottles are transported to filler via starwheel.
After entering filler, the bottle is held by gripper of lifting
cylinder and realizes up and down under effect of cam.
The filler adopts gravity filling way. Bottle mouth rises to open
filling valves and start filling. While product rises and plugs up
air return hole, the filling will be finished. After filling,
bottle mouth moves down and leaves the filling valve.
Capping unit
Bottles enter capper via transition starwheel. The anti-rotation
knife of capper blocks bottle neck to keep bottle vertical and
prevent rotation. Capping heads keep revolution and do rotation.
Under effect of cam, the action of gripping cap, sleeve cap,
screwing cap and discharging cap to finish the whole capping
course. The finished bottles are conveyed via bottle-out starwheel
onto bottle-out conveyor, and then are sent out of the combiblock.
The whole machine adopts console sealing windows, beautiful and
decent.
Water Blowing-Filling-Capping Combiblock Filling Machine for
Blowing unit
1) Special designed secondary blowing system monitors in time
pressure curve of bottle stretch process in each cavity to provide
accurate and timely parameters for technical adjustment, which is
more convenient for operators to adjust technical parameters.
2) Adopt manipulator transfer technology that cam mechanism has
precise control. Catch and send preforms at high speed and the
quality is reliable. Taking preform, sending preform, taking bottle
and sending bottle match action of opening and closing mould to
ensure that the movement process is exact and high efficient.
Taking preform, sending preform, taking bottle and ranking bottle
are finished automatically by manipulator, avoiding middle
pollution.
3) The cam mechanism controls exactly opening and closing of mould
frame. Special mould locking and pressurizing system and simple and
firm mould frame structure can control independently the blowing
parameters of each cavity. Good malfunction diagnosis function and
special blowing structure ensure the sealing reliability under
various pressure. The blowing pressure can be adjusted.
4) Stretch rod control exactly preform's axial stretch. The first
blow and second blow control preform's vertical stretch. By precise
adjustment of the first and second blow, the ideal distribution of
bottle wall thickness can be achieved.
5) Break conventional design and adopt structure of coaxial rotary
bushing with small cubage and light weight. Adopt two deep groove
ball bearings to fix two ends to make outside sleeve and core axes
concentric, to ensure that the rotary sealing ring is not easy to
be damaged. At the same time, increase one water back channel to
make the leakage water in Gore circle flows back along pipe,
ensuring that the water distributor won't have leakage.
6) Heater adopts extend 6-section short wave infrared ray
temperature control. Pre-heating zone and adjusting zone's lamps
can be controlled and adjusted respectively by technical
requirement. Equip real-time temperature monitoring system to
ensure stable and accurate process.
7) Cooling water channel and preform cooling system effectively
protect the bottle moth and avoid high temperature occurring in
outside wall of the preform. Our company's heating system can save
energy 20% compare with other suppliers.
8) Pneumatic line parts increase exhaust recycle system (according
to customer's requirement) can save air 30%-50% to save energy
consumption and reduce cost.
9) Parameters of heating temperature and blowing time can be set
according to different preform and bottle shapes. While changing
bottle shape, user only needs to call the pre-set parameters.
10) Adopt German lubrication system to do automatic lubrication for
the machine so that the machine can get enough maintenance and the
reduce worker's work.
11) Mould installation is easy and simple and it can be changed in
shortest time (within 2 hours). The Stop time of production is
reduced which is helpful to improve production efficiency.
12) Humanization design makes complicated industrial operation
close to people's habits. High-resoon HMI and multi-languages
option adapt to users from different area.
13) Real-time monitoring function and various malfunction alarm
hints and help, flexible and convenient parameter set can satisfy
various technical requirements.
14) Preform in the heating oven will be turned 180° through special
designed cam, make the bottle mouth down in an optimum processing
condition
15) According to customer's requirement, the whole system can be
maintained by Ethernet.
16) The mould is made of special aluminum alloy. The surface adopts
special hardening process to extend the mould life and lower the
production cost.
17) Preform infeed starwheel equipped with perform stuck inspection
system. In case the preforms get stuck, the unqualified perform
will be rejected automatically. After the unqualified preform get
out of the equipment, this system will self-reset.
18) For safety, the machine equips perfect and reliable security
door system and alarm device to ensure maximum safety for operators
