Description
Technical field
The present invention relates to a kind of inflatable body, refer to especially three inflatable bodies of a kind of blowing heat-resisting bottles machine.
Background technology
It is cooling that blowing heat-resisting bottles machine needs to utilize inflatable body to blow after moulding: the air blowing number of times of heat-resisting bottle forming process is three times, and therefore, the present invention is referred to as inflatable body three times.And three times current inflatable bodies comprise cylinder and central tube, described cylinder comprises cylinder body and is slidably mounted on the piston rod of cylinder interior, between described cylinder body and piston rod, be provided with application of force chamber, the piston of this piston rod is in application of force chamber, on described cylinder body, be positioned at the upper of piston, lower end arranges respectively the upper gas port and the lower gas port that are communicated with application of force chamber, on piston rod, be provided with axial passage, the lower end of piston rod is provided with the outlet side coordinating with heat-resisting bottle bottleneck, described central tube is up and down to be installed in passage and to run through cylinder body, this central tube is driven by lifting power plant, on described cylinder body, be provided with the first air inlet chamber being communicated with the passage of piston rod, central tube upper end is connected high-pressure pipe by elbow with flexible pipe.When use, the piston rod of cylinder moves down with the bottleneck of heat-resisting bottle and coordinates, and high pressure gas through the passage of piston rod, then blows out heat-resisting bottle coolingly from filling in end from the first air inlet chamber enters, and this action will be blown twice.And the action of blowing to be for the third time lifting power plant drive central tube to extend in heat-resisting bottle downwards blows, the elbow of its central tube upper end and flexible pipe can move along with central tube, therefore, the interface of the elbow of central tube is easily loosening, flexible pipe cracky.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of blowing heat-resisting bottles machine three inflatable bodies, these three inflatable bodies have been cancelled elbow and flexible pipe, utilize and on the cylinder body of cylinder, offer the air inlet of the second air inlet chamber as central tube, realize Fast Installation, make structure compacter, central tube air inlet and action are very reliable.
For solving the problems of the technologies described above, technical scheme of the present invention is: three inflatable bodies of blowing heat-resisting bottles machine, comprise cylinder and central tube, described cylinder comprises cylinder body and is slidably mounted on the piston rod of cylinder interior, between described cylinder body and piston rod, be provided with application of force chamber, the piston of this piston rod is in application of force chamber, the upper and lower end that is positioned at piston on described cylinder body arranges respectively the upper gas port and the lower gas port that are communicated with application of force chamber, on piston rod, be provided with axial passage, the lower end of piston rod is provided with the outlet side coordinating with heat-resisting bottle bottleneck; Described central tube is up and down to be installed in passage and to run through cylinder body, and this central tube is driven by lifting power plant, is provided with the first air inlet chamber being communicated with the passage of piston rod on described cylinder body; The top of described cylinder body is also provided with and independently the second air inlet chamber of the first air inlet chamber, and described central tube runs through the second air inlet chamber and coordinates with cylinder body seal; The lower end of described central tube is provided with several ventholes, and the middle part of described central tube is provided with air admission hole, and this air admission hole is communicated with the second air inlet chamber while putting in place central tube is descending.
As the preferred scheme of one, the number of described air admission hole is multiple, and marshalling is on the tube wall of central tube.
As the preferred scheme of one, in the passage of described piston rod, be provided with support frame, this support frame comprises inner core and the urceolus of concentric setting, is provided with the connecting portion with through hole between described inner core and urceolus, described central tube is slidably mounted in inner core.
Adopted after technique scheme, effect of the present invention is: these three inflatable bodies are provided with at the top of cylinder body and independently the second air inlet chamber of the first air inlet chamber, and described central tube runs through the second air inlet chamber and coordinates with cylinder body seal; The lower end of described central tube is provided with several ventholes, the middle part of described central tube is provided with air admission hole, this air admission hole is communicated with the second air inlet chamber while putting in place central tube is descending, like this, when central tube drives descending putting in place to be by lifting power plant, the gas outlet of the lower end of central tube enters in bottle, the air admission hole at middle part is communicated with the second air inlet chamber, now, toward the second inlet chamber is indoor while passing into gases at high pressure, gases at high pressure enter after the air admission hole of central tube enters the gas outlet, lower end from central tube and blow out heat-resisting bottle is carried out blowing for three times for the first time.This inflatable body has saved bend pipe and flexible pipe, avoids bend pipe and flexible pipe to move up and down with central tube and causes looseningly, also avoids flexible pipe breakage.
Again because the number of described air admission hole is multiple, and marshalling is on the tube wall of central tube, in the time that central tube moves up and down, sealing ring between central tube and cylinder body can rub with central tube periphery, this air admission hole arranges multiple sizes that can reduce air admission hole, increase the quantity of air admission hole, thereby can reduce the wear extent of air admission hole and sealing ring, increase the service life.
