The device for realizing six-step bottle blowing further comprises a pre-blowing air distribution disc 7 communicated with the first valve 2 through a first pipeline 6, a medium-blowing air distribution tank 9 communicated with the second valve 3 through a second pipeline 8, a high-pressure air distribution disc 11 communicated with the third valve 4 through a third pipeline 10, and an exhaust port 13 communicated with the fourth valve 5 through a fourth pipeline 12.
Wherein, the first pipeline 6, the second pipeline 8, the third pipeline 10 and the fourth pipeline 12 are not provided with switch valves.
The device for realizing six-step bottle blowing further comprises a fifth pipeline 14 communicated between the high-pressure air distribution disc 11 and the pre-blowing air distribution disc 7, a proportional pressure reducing valve 15 arranged on the fifth pipeline 14, a first one-way valve 16 and a two-position two-way electromagnetic valve 17. With the arrangement, when bottle blowing is started, high-pressure air output by the high-pressure air distribution disc 11 is depressurized by the proportional pressure reducing valve 15, is equal in pressure with pre-blowing air, and is input into the pre-blowing air distribution disc 7. The first check valve 16 is used to prevent the gas in the pre-blowing gas distribution plate 7 from entering the high-pressure gas distribution plate 11.
The two-position two-way electromagnetic valve 17 is used for controlling whether the pre-blowing gas adopts high-pressure gas or recovered gas. When the pressure of the recovered gas is too high, the recovered gas overflows through the proportional pressure reducing valve 15, so that the gas in the pre-blowing gas distribution disc 7 is depressurized and has the same pressure as the pre-blowing gas.

The second one-way valve 20 is used for preventing the gas in the middle blowing gas separation tank 9 from entering the high-pressure gas separation disc 11.
In the present embodiment, the sixth pipeline 18 is communicated with the third pipeline 10, and is communicated with the high-pressure gas distribution plate 11 through the third pipeline 10.

With this arrangement, at the time of recovery, the gas in the preform is recovered not only into the pre-blow gas distributor 7 through the first pipe 6 but also into the low-pressure gas distributor 22 through the seventh pipe 21. The gas in the seventh pipeline 21 is depressurized by a second pressure reducing valve 23 and then is input into a low-pressure gas distribution plate 22.
