Two steps in ChinaPetSemi automatic bottle blowing machine, the maximum speed can reach 1800 units per hour, while foreign PET bottle blowing machine has entered the high-speed period, the maximum speed of up to 15000 hours per hour. Guangzhou dayilong Packing Machinery Co., Ltd. in July 2002 the development of domestic first high-speed rotating PET blow molding machine, the machine speed can reach 8600 tickets / hour. Compared with the existing semi automatic batch type bottle blowing machine, the full automatic rotary high speed bottle blowing technology is a new bottle blowing technology, which can rotate continuously to reach the goal of high speed blowing. The blow molding machine has the advantages of high degree of automation, stable operation, safe and reliable, product from the part of the pollution, with the advantages of high production efficiency, can be widely used in food, beverages, cosmetics, pharmaceutical containers blowing, is currently the world's most advanced bottle blowing technology.
In our country, the development of high-speed bottle blowing machine, which limits the bottle blowing machine's high speed development bottleneck is the automatic level of automatic bottle blowing machine. Application in PET bottles of high speed blow molding machine and automatic control, Guangzhou dayilong Packing Machinery Co., Ltd. made beneficial attempt, has achieved considerable success.
The successful application of this automatic rotating high speed bottle blowing machine is automatic control. Application and function of automatic control in PET bottle blowing machine.
???
In the square billet, the machine adopts hopper type of bottle body, through special lifting mechanism, automatic discharging bottle is stable and reliable, which can automatically control the bottle blank according to the stock road stock, and the automatic control device can automatically control the bottle blank. The upper billet automatically replaces the bottle on the hand of the semi-automatic bottle blowing machine, which is an indispensable auxiliary high-speed bottle blowing device.
???
Using parameters to automatically adjust the temperature of bottle blank. Preform in heating furnace, through eight infrared uniformly rotating heating, eight infrared lamp can be independently of constant temperature, heating box and ventilation system, in order to avoid excessive in the outer wall of the bottle billet temperature, the heating system is equipped with infrared thermometer, the bottle blank heating temperature can be automatically adjust, in all levels of heating temperature through the electric control box screen display and intuitive, easy to set the temperature. By automatically adjusting the bottle blank temperature, the heating temperature of each bottle blank is the same, and the rate of blowing the bottle can reach more than 99.5%.
???
The machine adopts rotary automatic bottle blowing technology, which can realize continuous, automatic and intermittent blowing. It is the key technology to ensure the high speed of the machine.
???
Billet, steel billet, to bottle and bottle are automatically completed by 12 mechanical hand, after the bottle blank heating, by the manipulator will automatically prefabricated transported to the blowing bottle mould, such as infrared and optical detector signals to be transmitted to the computer to determine whether the seal, stretching and blowing. According to the technological requirements, in order to improve the production efficiency, blowing mould should speed up the cooling water, carry on the mold cooling, in the whole blowing process, all by computer control complete. Improve the efficiency and avoid the middle pollution.
???
Bottle blowing end, the manipulator will automatic bottle from the mold removed, and to receive quality testing, such as unqualified bottle shape will be automatically d, will be conveyed to the conveying belt, the bottle can be from the conveyor belt discharging storage in silos can also be transmitted through the air with direct access to the filling line, ensure high speed and high quality of bottle blowing.
Six, automatic trouble shooting
In the maintenance, programming logic controller is installed (programmable controller) electronic control board and machine all action, once the machine fault, it will operator to provide warning signals and fault diagnosis report, through the fault display operation, soon will be able to find fault reasons and get rid of as soon as possible.

The whole process from the top to the bottle inspection and monitoring system, are all automatic process, the level of technology to reach the domestic advanced level, to fill the domestic blank. This machine has applied for 7 national patents. At present, our country uses this kind of high speed blow bottle machine's enterprise, its equipment all is the import equipment. Now imported equipment (8600 bottles / hour), nearly 2000 yuan per unit, and the new development of this machine into the market, the price is only 10 / 1 to 1 / 8 of similar products, has a huge price advantage. The device successfully put on the market, will greatly reduce the cost of production of food, beverages, cosmetics, pharmaceutical and other industries, and our country joined WTO related industries related industries to make a certain contribution to resist the impact of foreign industry giants. ?
