Bottle blowing machine is a kind of equipment to make plastic particles into hollow containers by blow molding process. At present, there are two relatively common kinds. One is a hollow extrusion and blowing machine that USES PP and PE to form once; the other is a two-step bottle blowing machine that USES PET, PC or PP to form twice.Two-step bottle blowing machine is widely used in carbonated beverage bottles, mineral water bottles, cosmetics bottles, edible oil bottles, pesticide bottles, large-diameter bottles, high-temperature resistant bottles and other packaging containers made of crystallized plastics such as PET and PP in any shape.For many people who are new to plastic bottle industry, they need to know and learn a lot of knowledge before purchasing, so they need to purchase according to their own needs.The more expensive the bottle blower is, the better it is, but it may not be suitable for you.Because there are many types of bottle blowing machine, generally divided into semi-automatic bottle blowing machine, hand-inserted automatic bottle blowing machine, automatic bottle blowing machine.Flying pigeon allied bottle blowing machine can be customized according to different production and bottle capacity of customers.
Now briefly talk about the next two step bottle blowing machine in the production of the two steps.
The preform body is heated and softened by irradiating through infrared high temperature lamp tube. In order to maintain the shape of the bottle mouth, the preform mouth does not need to be heated, so a certain cooling device is needed to cool it.
Ii. Blow molding
In this stage, the preheated preforms are placed into the preformed blow mould, and the stretch rod is stretched down for high-pressure aeration to blow and draw the preforms into the desired shape of bottles.
Semi-automatic bottle blowing machine features:
1. Blowable PET bottle of 0.1-5 liters (one to two), 5L-20L (single cavity)
2. Using two mold cavities to blow 500 ml bottles, the production rate can reach 2000 bottles per hour
3. Advanced PLC control system, time control can be accurate to 0.01 seconds
4. Special air storage devices
5. Infrared lamp tube is used for heating, with strong penetration, preform rotation is heated, orbit revolution, uniform heating, fast and reliable
6. Different heating lamps are equipped with independent temperature control devices to ensure the ideal heating effect of the bottle embryo
7. The direction of the heating tube can be adjusted according to different bottle embryos
8. Only one person is needed for operation, no special training is required
9. Easy installation and startup
10. The scrap rate of finished products is less than 0.1%
Automatic bottle blowing machine does not need manual operation, and the output is 2000-8000 bottles per hour of different models, features:
A. Adopt advanced microcomputer control system with stable performance;
B. Automatic billet feeding by conveyor;
C. Infrared lamp tube is used for heating, with strong penetration, preform rotation is heated, orbit revolution, uniform heating, fast and reliable;
D. The width and height of the lamp tube and reflector in the heating zone can be adjusted to suit the heating of preforms of different structures, and there is an automatic temperature exhaust device to ensure the constant temperature of the baking passage;
E. Each mechanical action has a safety self-locking device. When a process fails, the program will automatically switch to a safe state;
F. Each movement is driven by oil pump, with pollution-free and low noise advantages;
G. The air path design divides the action and blowing into three parts, so as to meet the requirements of different pressure of blowing bottle and blowing action;
H. Adopt high pressure and hyperbolic arm connecting rod for clamping force;
I. Operation methods are manual and fully automatic;
J. The safe and reliable unique valve position design makes the air path clear at a glance;
K. The production process is completely automated, with the advantages of low investment, high efficiency, convenient operation, simple maintenance and safety, etc.
L. The bottle shall be free from contamination
M. The cooling system achieves ideal cooling effect
N. Easy to install and start
O. Bottle scrap rate is less than 0.1%
