The present invention is described in further detail with preferred embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, in bottle blowing machine stretch rod driving device, including：Mounting bracket 1, it is vertical in mounting bracket 1
Two guide rails 2 are provided with, two guide rails 2 are spaced and parallel and are arranged, and are both provided with sliding block 3 on every guide rail 2, every is led
Sliding block 3 on rail 2 has been fixedly connected with a toothed rack.In order to improve rack traveling comfort, every guide rail 2 in the present embodiment
On be both provided with a pair of of sliding block 3, each pair of sliding block 3 is fixedly connected with the upper/lower terminal of corresponding rack.Based on two toothed racks difference
Carry-over bar 4 and driven rack 5, stretch rod 6 are fixedly connected on the lower end of driven rack 5, specifically, the upper end of stretch rod 6
It is clamped by fixture block 61, fixture block 6 is bolted on the lower end of driven rack 5.Stretch rod 6 using the above structure with driven tooth
The advantage that 5 phase of item is fixed is：Convenient for adjusting the mounting height of stretch rod 6.
Active rack 4 is connected with driving part, and the driving part is cylinder 7, and cylinder 7 is mounted on mounting bracket 1
On, the piston rod of cylinder 7 is connected with active rack 4, and the piston rod of cylinder 7, which extends downwards, can drive active rack 4 to transport downwards
It is dynamic.In the present embodiment, it is provided with limited block 9 in the mounting bracket 1 of 4 lower section of active rack, limited block 9 can be blocked in actively
On the sliding block 3 of 4 lower end of rack.
It is provided with gear in mounting bracket 1 between active rack 4 and driven rack 5.The gear packet
It includes：Mounting base 8 is provided with the first installation axle 81 and the second installation axle 82 in mounting base 8, first is equipped in the first installation axle 81
Gear 811, the double gear of integral structure is equipped in the second installation axle 82, and double gear is followed successively by second gear from inside to outside
821 and third gear 822, the diameter of first gear 811 is less than the diameter of second gear 821, first gear 811 and second gear
821 intermeshings.The mounting base 8 can be mounted in mounting bracket 1 forward or backwards, mounting base 8 in the present embodiment
Upper and lower end has been symmetrically arranged a pair of bolts hole 800, and mounting base 8 is detachably fixed by bolt mounted on installation
On holder 1.As shown in Figure 1, when 8 forward direction of mounting base is mounted in mounting bracket 1, first gear 811 is nibbled with 4 phase of active rack
It closes, third gear 822 is meshed with driven rack 5；As shown in Figure 3, Figure 4, when mounting base is reversibly mounted in mounting bracket 1
When, third gear 822 is meshed with active rack 4, and first gear 811 is meshed with driven rack 5.In driving part, i.e. gas
Under the driving of cylinder 7, active rack 4, which moves downward, can drive driven rack 5 that stretch rod 6 is driven to move downward, to realize to bottle
The axial tension of base.
Operation principle is as follows：When the positive installation of mounting base 8, the piston rod of cylinder 7 extend downwardly driving active rack 4 to
Lower movement, active rack 4 drive first gear 811 to rotate, and first gear 811 drives second gear 821 to rotate, third gear
822 and then rotate together, and third gear 822 then can drive driven rack 5 to move downward, and such stretch rod 6 will be transported downwards
It is dynamic, to compress the bottom of bottle base downwards and so that bottle base is axially stretched.When the sliding block 3 of 4 lower end of active rack is kept out
When on limited block 9, stretch rod 6 has been moved downwardly to extreme position.Due to the diameter of the first gear 811 of first gear 811
Less than the diameter of second gear 821, therefore when 8 forward direction installation of mounting base, the speed that driven rack 5 moves downward is less than driving tooth
The speed that item 4 moves downward.When mounting base 8 is reversely installed, the piston rod of cylinder 7 extends downwardly, and driving active rack 4 is downwards
Movement, active rack 4 drive third gear 822 to rotate, and second gear 821 then and then rotates together, and second gear 821 drives the
One gear 811 rotates, and first gear 811 then can drive driven rack 5 to move downward, and such stretch rod 6 will move downward, from
And compress the bottom of bottle base downwards and so that bottle base is axially stretched.When mounting base 8 is reversely installed, driven rack 5 is transported downwards
Dynamic speed is more than the speed that active rack 4 moves downward.
From the foregoing, it will be observed that the speed that driven rack 5 moves downward can be adjusted by the installation forward or backwards of mounting base 8
Degree adjusts the speed that stretch rod 6 pulls down stretched bottle preform, so that the tensile speed of stretch rod 6 adapts to different bottle-type.This
The driving device of stretch rod can be suitable for the blowing of different bottle-type in a set of bottle blowing machine of sample, can root in actual production process
It needs that mounting base is installed forward or backwards according to bottle-type, adjusts to 6 speed of stretch rod extremely convenient.In addition, the drive of entire stretch rod
Dynamic device noise in action process is low, and which significantly improves the environment of worker's work.
