BLOW MOLDING MACHINE
Blow molding machine is a kind of machine that can blow bottles.
The most simple explanation is that it can blow plastic bottles
(softened into liquid) or good bottle preforms into bottles by
certain technological means. The bottle blowing machine is
convenient and fast, with large molding quantity. After it
appeared, it replaced most of the manual bottle blowing and was
adopted by most beverage enterprises.
Plastic hollow containers are widely used in beverage, medicine,
cosmetics, food and chemical industry because of their light
weight, low price and high safety. More and more manufacturers
choose plastic containers instead of glass containers.
Nowadays, the most advanced equipment, molds and raw materials in
the plastic industry are all presented one by one. New technologies
and new applications emerge in endlessly. Throughout the field of
plastic hollow molding, it is also fruitful. With the world's
soaring oil prices, the price of plastic raw materials is also
high, and the development of alternative products with low energy
consumption and low raw materials is also one of the market trends.
In order to keep the shape of the bottle mouth, the bottle mouth
does not need to be heated, so it needs a certain cooling device to
2) Blow molding
In this stage, the preheated preform is put into the blow mould,
and the preform is blown into the required bottle by high pressure
The bottle blowing machines on the market are generally divided
into automatic and semi-automatic.
The automatic bottle blowing machine combines the two operations of
bottle blowing through the operation of the manipulator,
eliminating the process of manually putting the preheated bottle
blank into the blowing mold. Greatly speed up the production rate,
of course, the price is higher than the semi-automatic.
How to choose the type of bottle blowing machine you need must be
the most concerned topic.
Generally speaking, choose the model of bottle blowing machine
according to the products you need. For different dosage
manufacturers, the general concern is how many cavities you needed,
the size of the bottle volume, and the output per hour.
It is very important to choose the model according to your own
Step 1. Place the bottle preform in the bottle preform container
and enter the bottle preform positioning device automatically
through the conveying device.
Step 2. The bottle preform mouth is upward, the bottle preform is
automatically loaded on the bottle preform holder, and then sent to
the drying channel.
Step 3. After heating, the bottle preform is sent to the blowing
and drawing platform, and then the mold is locked, followed by low
pressure blowing and drawing, high pressure blowing and drawing,
exhaust, and finally the mold is opened.
Step 4. The finished bottle is taken down from the blowing platform
by the automatic demoulding system.
Beverage enterprises have two urgent needs for bottle blowing
equipment. One is that because the price of plastic raw materials
continues to rise, beverage enterprises are always thinking about
how to reduce packaging costs to maximize profits, so they need to
use advanced bottle blowing equipment to produce lighter bottles.
The other is that due to the rapid changes in the market, beverage
manufacturers must pay more and more attention to beverages Short
life cycle makes flexible response, corresponding to the PET bottle
production in the increasingly frequent product update problem, in
the production process need to change the mold time to the minimum.
These two urgent needs give blowing equipment suppliers a big
1. No charging at charging position: several conditions need to be
Is there no material in the hopper? If so, it needs to be fed
No: please check whether the control contactor of the hoist is in
the power on state. If it is in the power on state, check whether
the motor is in the power on and load state as soon as possible,
because it is likely that the bottle preform is stuck in the
lifting belt. At this time, the simplest method is to help lift
If the control contactor of the elevator is not in the power on
state, please check whether the bottle embryo detection eye is not
in the same line with the reflector.
2. Feeding old card feeding tray: This is a headache. From the
experience, if the length of the bottle preform is longer and the
cutting weight is larger, then this phenomenon is less.
3. The bottle cannot be taken out of the mold after blowing.
First of all, the mold should be opened and closed manually if it
is in normal operation.
Please check your exhaust time setting. If the exhaust time setting
is normal, and if it fails only by blowing the bottle every time,
it can be judged that it is the exhaust valve problem. Please open
the exhaust valve and check its spring and seal condition (another
phenomenon of this kind of fault is that the exhaust sound is loud
or the exhaust sound is not clean).
If you encounter the situation that many molds can't be opened
occasionally due to normal production, please check whether there
is a screw in the clamping pin. In addition, please check whether
the clamping force is too large. If it is too large, it should be
readjusted according to the standard.
4. The bottle is always pinched
Whether the position of the manipulator is misplaced.
5. Two robots collide
This situation needs to reset the manipulator manually, which is
caused by dislocation.

Essential knowledge of safe operation of automatic bottle blowing
|1||Before start-up of each shift, all moving parts must be lubricated
once. (manipulator, manipulator guide rail, mold opening and
closing guide rail)|
|2.||The arm swing can be added once every (3-4) days. Large chain and
small chain of heater can be used once a month. Check the main
engine reducer and heater reducer for oil shortage frequently. The
main engine bearing can be added once every 3 months.|
|3.||Before production, check whether the moving parts are firm, whether
the screws are loose and fall off, especially where the impact
force is strong, and whether the belt drive part is abnormal.|
|4.||Check whether the high pressure air source, low pressure air
source, power supply and water source are normal.|
|5.||Check whether the emergency stop switch, safety door switch and
protection device detection switch are normal.|
|6.||Check whether the heating head enters the embryo and the embryo
dropping part works normally. If the embryo is not inserted in
place, the nut of embryo pressing device can be adjusted.|
|7.||Check whether the lamp tube is damaged or broken. It should be
replaced in time.|
|8.||Check the pneumatic components for air leakage and sensitivity.|
|9.||Check whether the triplet has abnormal air leakage, whether it is
blocked, and whether the water storage in the water cup is too
|10.||When the solenoid valve of automatic bottle blowing machine is
abnormal, it should be cleaned in time.|
