Detailed description of the invention
A kind of bottle blowing structure, as depicted in figs. 1 and 2, comprise the pressure pan 1 with external air source equipment 7 pipeline connection, pressure pan 1 blows valve 6 pipeline connection with low-pressure relief valve 5 and master respectively, described master blows valve 6 and is communicated with gassing pipe for bottle blowing, gassing pipe there is air bleeding valve by pipeline connection, described low-pressure relief valve 5 is communicated with low pressure gasholder 3 by pipeline, low pressure gasholder 3 is communicated with pre-blowing valve 10 by pipeline, pre-blowing valve 10 and gassing pipe pass through pipeline connection, low pressure gasholder 3 is also communicated with low pressure recovery valve 11 by pipeline, low pressure recovery valve 11 by pipeline connection to gassing pipe, high pressure gas enters pressure pan 1, enters low pressure gasholder 3 after being reduced pressure by low-pressure relief valve 5, then enters gassing pipe by low pressure gasholder 3 through pre-blowing valve 10 and carry out pre-blowing to bottle base 12, high pressure gas is entered gassing pipe by pressure pan 1 and carries out final blowing to bottle base 12 through the main valve 6 that blows and form container, after container blowing completes, gas in container is recycled in low pressure gasholder 3 through low pressure recovery valve 11 by gassing pipe, stops reclaiming low-pressure gas until gas in container Pressure Drop is low to moderate when low-pressure gas reclaims minimum.
Described pressure pan 1 also with middle pressure pressure-reducing valve 4 pipeline connection, middle pressure pressure-reducing valve 4 is communicated with middle pressure air accumulator 2 by pipeline, middle pressure air accumulator 2 is communicated with middle pressure purge valve 8 and middle pressure recovery valve 9 respectively by pipeline, described middle pressure purge valve 8 and middle pressure recovery valve 9 by pipeline connection to gassing pipe, high pressure gas enters pressure pan 1, enter middle pressure air accumulator 2 after being reduced pressure by middle pressure pressure-reducing valve 4, then by middle pressure air accumulator 2 through middle pressure purge valve 8 enter gassing pipe to bottle base 12 carry out the secondary after pre-blowing blow; Bottle base 12 is after finally blowing becomes container, and gas in container presses recovery valve 9 to be recycled in middle pressure air accumulator 2 in being passed through by gassing pipe, stops reclaiming medium pressure gas until gas in container Pressure Drop is low to moderate when medium pressure gas reclaims minimum.Because low pressure blowing bottle base is only make bottle base preformed, be stretched to maximum height simultaneously, therefore, by high pressure blow-gas, bottle base one-shot forming is put in place again, the large usage quantity of gases at high pressure will be made like this, relatively expend, even if reclaimed low-pressure gas by recovery valve, also still most of energy can be wasted, therefore, by arranging middle pressure air accumulator, thus, when bottle blowing, blown further by medium pressure gas, bottle base can be made shaping further, and then when with high pressure bottle blowing, the loss of gases at high pressure can be reduced, container rapid shaping can be made, and the medium pressure gas in container is reclaimed, medium pressure gas can also be recycled, significantly reduce external air source to the supply of medium pressure gas, energy-conserving and environment-protective, processing cost is low, in addition, by three blowings, stability under loading in bottle base expansion process can be made, expansion process even variation, bottle base is damaged when bottle base can not be caused to be expanded to maximum suddenly.

3 , P
1, p
2 and P
3 meet relation: P

3 )/2.By the relation in setting pressure pan, middle pressure air accumulator and low pressure gasholder between gas pressure value, thus outside effectively ensureing that container blowing is shaping, also can reduce the waste of gases at high pressure, control the consumption of gases at high pressure.
A kind of bottle blowing method, its step is as follows: (1) closes all valves, more closed bottle blowing mould behind appropriate location preformed bottle base 12 being delivered to bottle blowing mould, gassing pipe is aimed at preformed bottle base mouth, and seals preformed bottle base mouth; (2) open low-pressure relief valve 5, the gases at high pressure entered in pressure pan 1 by external air source equipment 7 flow in low pressure gasholder 3 after decompression, inflate it, after inflation, close low-pressure relief valve 5; (3) pre-blowing valve 10 is opened, gas in low pressure gasholder 3 carries out pre-blowing via gassing pipe to preformed bottle base 12, meanwhile, contact bottom preformed bottle base by servo control mechanism or other mechanical type drawing mechanism, in first time blow molding process, stretch bottle base to maximum height; (4) close pre-blowing valve 10, open master and blow valve 6, the gas in pressure pan 1 is blown to preformed bottle base again via gassing pipe, final container blow molding; (5) close master and blow valve 6, low pressure recovery valve 11 is opened, gas in container is recycled in low pressure gasholder 3 by gassing pipe, when the gas pressure in container is reduced to low-pressure gas recovery minimum, low pressure recovery valve 11 is closed, this partially recycled low-pressure gas not only may be used for the pre-blow molding of bottle base blowing next time, can also be used for the source of the gas supply of other low-voltage driving mechanism, as drawing mechanism or Da Pei mechanism etc.; (6) open air bleeding valve, discharged by residual gas in container, complete container blowing and gas removal process, because this part gas pressure be discharged is low, flowing slowly, and is unfavorable for the control of blowing the container process time, therefore, need discharge as waste gas; (7) repeat step 3 to step 6, move in circles, till all preformed bottle bases have been blown.Reclaim by carrying out classification to the gas in container during during bottle blowing first and again bottle blowing, and the low-pressure gas of recovery is applied in bottle blowing next time, circulation repeatedly, therefore, the supply of external air source to medium pressure gas and low-pressure gas can be reduced, reduce expending of gases at high pressure further, improve the utilization rate of the energy, reduce external air source equipment and be supplied to the compressed air energy consumption of blowing container machine and the processing cost of blowing container machine, energy-conserving and environment-protective.
In step 2, in opening, press pressure-reducing valve 4 simultaneously, entered during gases at high pressure in pressure pan 1 flow into after decompression by external air source equipment 7 and to press in air accumulator 2, it is inflated, after inflation, in closedown, presses pressure-reducing valve 4; After step 3, close pre-blowing valve 10, purge valve 8 is pressed in first opening, gas in middle pressure air accumulator 2 carries out secondary air blowing via gassing pipe to preformed bottle base, purge valve 8 is pressed in closing again subsequently, open master and blow valve 6, the gas in pressure pan 1 is blown to preformed bottle base for the last time via gassing pipe, final container blow molding.By recycling medium pressure gas, thus after pre-blowing bottle parison, preformed blowing can be carried out to bottle base, because this part medium pressure gas is also not enough to make the disposable blowing of bottle base put in place, bottle base can only be made to be blow molded into close to shaping shape, again by the blowing of a small amount of gases at high pressure, the blow molding of container can be completed, greatly reduce the consumption of gases at high pressure, energy-conserving and environment-protective, reduce production cost.
In step 5, close master and blow valve 6, press recovery valve 9 in first opening, gas in container is recycled in middle pressure air accumulator 2 by gassing pipe, and when the gas pressure in container is reduced to medium pressure gas recovery minimum, middle pressure recovery valve 9 is closed; Low pressure recovery valve 11 is opened subsequently, and gas in container is recycled in low pressure gasholder 3 by gassing pipe, and when the gas pressure in container is reduced to low-pressure gas recovery minimum, low pressure recovery valve 11 is closed.By reclaiming medium pressure gas and low-pressure gas recovery, further can reduce the consumption of gases at high pressure, reducing production cost.
It is 18 ~ 24 bar that described medium pressure gas reclaims minimum scope, and set according to force value difference required in bottle blowing process, the medium pressure gas of this scope effectively can blow bottle base by secondary.
It is 10 ~ 14 bar that described low-pressure gas reclaims minimum scope, by reclaiming this portion gas, thus this portion gas can be utilized to carry out pre-blow molding to bottle base, this portion gas can also be used for Da Pei mechanism or drawing mechanism etc., improve the utilization rate of gas recovery, reduce production cost, energy-conserving and environment-protective.
