Full automatic plastic bottle blowing machine working principle of the whole system is relatively simple, because only this part of the supply stretching cylinder and pre blow, mounting structure is also very convenient, worthy of note is recovery volume and consumption balance between the gas, so in the production of different capacity bottle should a good grasp of the relationship between supply and demand.
  Although the system will only gas recovery provided supply tension, pre blowing two parts, it is there is a fly in the ointment, but its investment is small (to SBO10/14 as an example to only about twenty thousand, specific according to the parts price), returns (annual cost savings from 16 to 20 million), independent strong (failure or other reasons, the use of raw gas supply system), high flexibility, simple installation, convenient), very much in line with the basic principles of our technological transformation projects, make the product more competitive market.
  Boot idling not blowing in and low pressure gas through the original pipe electromagnetic valve to the stretching cylinder gas storage, recycling gas storage and stretching cylinder storage gas is separated by a one-way valve, recycling the gas storage in low-pressure gas, at this moment, the whole system of tensile and pre blowing system keep in did not transform the former undisturbed.
  When the device starts blowing, high pressure gas bottle through the three-way valve 10 exhaust pipe through the one-way valve 12 into the gas recovery tube 6, a circle of recycling equipment running enough gas, using manual solenoid valve 1 closed original tensile pressure inlet and pre blow air inlet pipeline, the stretching cylinder and the pre blow by recycling gas tube gas, due to different bottle volume production (0.6L, 1.25L, 2.0L etc.), we can properly open the exhaust valve 9, discharge the excess gas from the muffler, gas and gas consumption to keep the recovery of balance, such as recycling gas tube still has residual gas, through the 15bar 4 safety valve emissions, so safe the valve must have sufficient flow to excess exhaust gas, stop blowing open the manual solenoid valve by the original low-pressure and pre blow gas pipeline.
