II.Working principles and structure
1.Working principles
Rotary infrared heater heats pre-forms by moving pre-forms to pass through infrared heating area twice. by this method, heating is uniform and of high efficiency,
Infrared heating area is strictly divided into seven zones of A,B,C,D,E,F,G from up to down, Temperature requirements for all parts of pre-form are satisfied by controlling temperature of corresponding zones.
The feeding of pre-form for heating and taking away of heated pre-form shall be conducted manually which is simple and convenient.
Rotary infrared heater consists of heating system, cooling system, pre-form conveying system, constant temperature system,etc.
1>.Infrared heating system:
28pcs infrared tubes are fixed by an adjustable fixing frame in two rows and seven zones. Distance between cartridge heaters can be adjusted freely. Boards which can reflect light and absorb heat are installed inside the drying tunnel, so as to improve utilization rate, absorb surplus energy and prevent the outer wall of pre-form being overheated and whitening.

Infrared heating tubes are controlled by digital display intelligence pressure regulator with controllable silicon, featuring clear visual display, easy operation and accurate and stable adjustment.
2>.Cooling system:
The device is air cooled, compressed air sends cooled air to the mouth of pre-form directly through square tubes to cool the pre-form openings being heated in the drying tunnel for the purpose of avoiding distortion of pre-form.
3>.Pre-form conveying system
Pre-form conveying system includes pre-form support revolution chain unit, rotation chain unit. the power-driving system employs dampening and speed-reduction,gear chain transmission, featuring: low noise, low failure rate and easy for maintenance.
4>.Constant temperature system.
A temperature sensor is mounted inside the drying tunnel, which is used to collect signals and control exhaust fan. A constant temperature can be set according to the requirements to guarantee constant temperature in the drying tunnel.
III.Operation method.
1.Basic operation:
First open the front door, Turn the circuit Breaker to ON and close the door, press the RUN key on the speed-regulation panel ⑫of main unite. Then turn on the speed-regulation switch ⑯ of the auxiliary unit and the intelligence voltage regulator switch⑮. The valve of Temperature controller ⑫ MTD

90℃) generally has been set by factory.
The intelligence voltage regulator is divided into seven areas of TCA,TCB,TCC,TCD,TCE,TCF,TCG.The user may choose proper areas to vary the valve by pressing the “ “ “ “keys on the panel depending on the conditions of pre-form to be heated, The valve displayed on the panel is voltage which decides the capacity of heaters.
Note: as above operation for production through selecting our mould and pre-form
2.Practical Operations
1>.The heating of pre-forms are subject to high or low temperature and long or short time through heating areas, For large pre-form with thick walls, the heating temperature shall be high, besides increasing the valve of voltage regulator, and can also properly reduce valve of speed-regulator of main unit so as to prolong heating time. On the one hand, for small pre-form with thin walls, the intelligence voltage regulator shall be set at lower valve and the speed regulator shall be set at high valve so as to obtain the favorable temperature for blowing of pre-forms.
2>Before mass production, a test with 1-2pcs of pre-forms is required to obtainthe best heating temperature.
3>.If one pre-form fails to be blown, it can be re-heated for blowing again.
3.Details of heating pre-forms in an oven.

1.To be opened layers of lamps are subject to height of pre-form.. For example, Pro-form A as show in the above figure need 5 layers of lamps, so there will be needed to open A,B,C,D,E five voltage-regulator table; Pre-form B need open 7 layers of A,B,C,D,E,F,G
2.The valve of Frequency converter shall be set at 20HZ in case of blowing mineral water bottles, and 15 HZ for high-temperature resistant bottles. The valve of Temperature controller shall generally be set at 95℃ for mineral water bottle and 110℃ for hot-resistant bottles.
3.Generally, the voltage of lamp at lower layers shall be slightly higher than that of upper layers. For example, in case of pre-form A, the voltage is 80v at layer 1, 70v at layer 2,60v at layer 3,50v at layer 4, 55v at layer 5. in case of pre-form B, the voltage is 85v at layer 1.80v at layer 2,75v at layer 3,70v at layer 4,60v at layer5,50v at layer 6,55V at layer 7.

The above parameter is only for reference.
4>.How to get the standard temperature.
Take the above as an example, the frequency converter shall be set at 20HZ for blowing mineral water bottles. First turn the speed regulator to 18HZ,then vary the voltage of various layers to allow the pre-form get slightly whiten in each part after moving a cycle in the oven. Finally turn the speed to 20HZ. If the pre-form looks clear after moving a cycle in the oven, the temperature at this point is the standard temperature.
IV.Basic operation for all parts.
1.Lamp frame adjustment.

  2. Plug the four core power plug, or connect main machine to 220-v power supply.
  3. Connecting air tube, pumping the air.
    VI. Operation and commissioning
  4. The dismantling and installation of blowing bottle mould, place the mould tight on the mould plate. The mould should be installed vertically and parallel. The two mould should be face to face correctly. Then, tighten the fixing nails.
  5. The adjustment of stretching pole and sealing cylinder.
    Loose the fixed nails on the back of the cylinder, make the stretching pole vertical against the opening, and be centered and the pole head should nearly touches the bottom of the bottle mould. The bottom of poles should be absolutely on the same line, not one high, the other low. Then tighten the fixed nail.
  6. Heating of preform and bottle blowing.
    Connecting to power supply, switch on 4 air switches. Turn on the switches of the fans on the plate. Adjust the six electrical positions so that the IR heating tubes have the required volts according to the data supplied by the manufacturer. The alarming temperature should be between 95-100 centigrade degree. After 30 minutes, the exhaustion fans will start, and then you can put preforms into the oven.
    After the heating up or preforms coming out from the oven, put the preform on
    the blowing mould, press the start up button, then it will complete the following procedure as follows:
    Closing–sealing stretching—left air blowing retention/right air blowing retention —- left air blowing/right air blowing.
    Then the procedure or action will be repeated. This is the process of production. If the trial blowing is successful, then put the preforms into the oven. Note: please do not put all the preforms into the oven before the trial blowing.
