At present, the bottle blowing mode that domestic and international bottle blowing machine is adopted mainly contains following several: (1) is at the uniform velocity heated and is at the uniform velocity blown mode, promptly at the uniform velocity the rotation mould bases on uniform a plurality of one-mode cavity moulds, bottle base is at the uniform velocity heated by heating lamp box district, and the bottle base after heating enters corresponding mould successively and blows.Under this blowing mode, the commentaries on classics because mould need not stopped transport, so its mould bases complex structure, difficulty of processing is big; (2) the stepping stepping blowing mode of heating.This blowing mode is applicable to multi-cavity mold, during blowing, will have a plurality of bottle bases that heat to enter mould simultaneously.Because a plurality of bottle bases of blowing will stop several stepping periods in heating lamp box district simultaneously, and each bottle base present position difference in the lamp box district, so being heated evenly property be cannot say for sure to demonstrate,prove.Therefore, cause sizable difficulty for the adjustment of its temperature control and equipment, and its current consumption is also bigger; (3) the stepping blowing mode of at the uniform velocity heating.Its operational process adopts two transmission chains: one is the transmission chain of heating of uniform motion, at the uniform velocity heats by heating lamp box district to guarantee bottle base; It two is the bottle blowing transmission chain of step motion, and this kind mode needs that the bottle base that heats is transported to bottle blowing transmission chain (or put into mould with the artificial bottle base that directly will heat) by a transition mechanism and blows.Its shortcoming is that device structure is huge, complicated, cost is high or labor strength is big.

The purpose of this utility model just is in order to overcome and to solve existing bottle blowing machine complex structure, huge, its temperature control and establish that to adjust difficulty big, shortcoming that current consumption is big, cost is high or labour intensity is big and problem, research relate to a kind of simple in structure, scantlings of the structure is less, adjust and safeguard, save the energy easily, cost is low, the bottle blowing machine chain-drive mechanism of the stepping bottle blowing of realizing at the uniform velocity heating.

The utility model is realized by following structure technology scheme: the structural representation of the bottle blowing machine chain-drive mechanism of the stepping bottle blowing of realizing at the uniform velocity heating (is illustrated as one and goes out four bottle blowing machine synoptic diagram) as shown in Figure 1; The K of its removable right tightener sprocket and wheel seat 5 thereof to view as shown in Figure 2; The A-A sectional view of its fixed tensioning sprocket wheel and wheel seat 6 thereof as shown in Figure 3.This chain-drive mechanism is by bottle blowing mould and matched moulds drawing mechanism 1 thereof, stepper drive sprocket wheel 2, guide rail 3, cylinder 4, removable right tightener sprocket and wheel seat 5 thereof, fixed tensioning sprocket wheel and wheel seat 6 thereof, set nut 7, tensioning spring 8, free-wheeling system 9, a left side connects guide pillar 10, at the uniform velocity drive sprocket 11, lamp box district 12 heats, driving chain 13, bottle base support fixture 14, removable left tightener sprocket and wheel seat 15 thereof, work top 16, tightener sprocket and wheel seat 17 thereof, right guide pillar 18 grades that connect connect and compose jointly, its mutual alignment and annexation are:

sprocket wheel
