Title:
DRIVE APPARATUS OF STRETCHING ROD IN BOTTLE BLOWING MACHINE
Document Type and Number:
WIPO Patent Application WO/2019/127917
Kind Code:
A1
Abstract:
A drive apparatus of a stretching rod in a bottle blowing machine, comprising: a driving gear rack (4) and a driven gear rack (5) are respectively fixed on a sliding block (3) of two guide rails (2) of a mounting bracket (1), a stretching rod (6) being fixed to the driven gear rack (5), the driving gear rack (4) being connected to a drive component, and a variable speed mechanism between the driving gear rack (4) and the driven gear rack (5) comprising: a first gear wheel (811) being mounted on a first mounting shaft (81) of a mounting base (8), a double-row gear wheel having an integral structure being mounted on a second mounting shaft (82) of the mounting base (8), the double-row gear wheel comprising a second gear wheel (821) and a third gear wheel (822), the diameter of the first gear wheel (811) being less than the diameter of the second gear wheel (821), the first and second gear wheels (811, 921) being mutually engaged, and the mounting base (8) being capable of being mounted in a forward direction or a reverse direction, such that the first gear wheel (811) and the third gear wheel (822) respectively engage with the driving gear rack (4) and the driven gear rack (5), or respectively engage with the driven gear rack (5) and the driving gear rack (4); Driven by the drive component, the stretching rod (6) moves downward, and thereby implements axial stretching of a bottle preform. The apparatus can adjust the speed of the stretching rod, and can therefore adjust to different bottle types.
