Abstract
The utility model provides a medium blowing type stretching rob mechanism, relating to the blowing bottle machinery technical field, in particular to a blowing type stretching rob mechanism of even blowing, high yield and wide range of application. The technical proposal is that the stretching rob is provided with holes inside, is provided a plurality of radial through holes evenly at the upper end and is provided with a plurality of radial through holes communicated with inner holes of a connecting rob at the position where the lower end is connected with the connecting rod; a bottle opening sealing block is arranged between the stretching rob and the inner wall of the bottle opening, the lower end of the bottle opening sealing block is sleeved with a locknut and is inserted into an hole at the upper end of a clamping device, the upper end surface of the claming device contacts with the lower end surface of the locknut. The utility model has even airflow during blowing bottle blanks and thereby the bottles blew are even in wall thickness and the yield rate is improved notably; the stretching rob can adopt a bigger diameter so as to improve the strength, extend the service life, which does not affect the effect of blowing bottles, but is beneficial for blowing the bottles with small openings and the bottles with super height and size, thereby greatly expanding the application scope of the utility model.
Description
Technical field:
The utility model relates to the bottle blowing field of mechanical technique, refer in particular to a kind ofly blow evenly, yield rate is high and the middle air blowing type stretching linkage that has wide range of applications.
Technical background:
The present bottle blowing machine that generally uses, its stretching bar is a solid hopkinson bar, between its stretching bar and bottleneck sealing block, interspace in advance, gas promptly thus the space enter a bottle embryo, and radial drawing bottle embryo is to make it moulding.Because the gap between bottle embryo inner chamber and the stretching bar is less, when air-flow is entered bottle embryo by the space between stretching bar and the bottleneck sealing block, the motion of air-flow will be hindered, thereby the bottle embryo is gone up ground distortion successively by reaching down, thereby wall unevenness is even after will causing the bottle moulding, and its percent defective is corresponding also higher; Again because air-flow is to enter bottle embryo from the space between stretching bar and the bottleneck sealing block, thereby the stretching bar is generally done thinnerly to solve said flow obstruction problem, but therefore the intensity of stretching bar will significantly descend, deform easily, and will directly cause percent defective to increase, and stretching bar self life-span also will significantly descend.
Summary of the invention:
The middle air blowing type stretching linkage that the purpose of this utility model is to provide a kind of blows evenly, yield rate is high and have wide range of applications.
The utility model is achieved by the following technical solution: the inside of stretching bar is offered porose, and its upper end evenly offers some radial direction through hole, and the junction of its lower end and connecting rod offers some radial direction through hole that the endoporus with connecting rod connects; The bottleneck sealing block is arranged between the inwall of stretching bar and bottleneck, and its lower end is arranged with locking nut, and inserts in the hole of clamping device upper end, and the upper surface of clamping device contacts with the lower surface of locking nut; Between clamping device and stretching bar, be provided with sealing ring and guider, between clamping device and bottleneck sealing block, also be provided with sealing ring, and between bottleneck sealing block and stretching bar, also be provided with guider.
Because stretching bar of the present utility model inside is offered porose, the air-flow of bottle blowing flows into from the endoporus of connecting rod, and enter the slotted hole of stretching bar inside by the radial direction through hole of stretching bar and its junction, flow into the bottle embryo by the equally distributed some radial direction through hole in stretching bar upper end again, thereby the air pressure that acts on bottle embryo inwall is even, bottle wall thickness behind blow molding is even, and yield rate significantly improves; Again because air-flow enters a bottle embryo from the equally distributed radial direction through hole in stretching bar upper end, thereby the influence of gap length is very little between air-flow tension boom and the bottle embryo, thereby can do more the diameter of stretching bar to improve the intensity and the service life of stretching bar, and can avoid the distortion of bar that stretches, and then the rate of significantly reducing the number of rejects and seconds; And after the intensity of stretching bar improved, during with the bottle of the utility model blowing bottle or especially big, extra-high-speed, yield rate was still very high, thereby range of application of the present utility model is more extensive.
Description of drawings:
Accompanying drawing is a sectional structure schematic diagram of the present utility model
See accompanying drawing, the utility model comprises stretching bar 1, bottleneck sealing block 2 and connecting rod 3, the inside of stretching bar 1 offers porose 11, evenly offer some radial direction through hole 12 in the top, insert in the radial direction through hole 32 of connecting rod 3 ends the lower end of stretching bar 1, insert section at it and offer some radial direction through hole 13 that the endoporus 31 with connecting rod 3 connects, and insert section at it and be outside equipped with the boss 34 that goes in ring, sealing ring 33 places and goes in ring between boss 34 inner surfaces and the connecting rod 3, the end of stretching bar 1 is provided with thread segment, and has nut to be screwed in thread segment; Bottleneck sealing block 2 is arranged between the inwall of stretching bar 1 and bottleneck, and its lower end is arranged with locking nut 24, and inserts in the hole of clamping device 22 upper ends, and the upper surface of clamping device 22 contacts with the lower surface of locking nut 24; Between clamping device 22 and stretching bar 1, be provided with sealing ring 21 and guider 23, between clamping device 22 and bottleneck sealing block 2, also be provided with sealing ring 21, and between bottleneck sealing block 2 and stretching bar 1, also be provided with guider 23.
The specific embodiment:
When using the utility model, at first use the fixedly position of bottleneck of clamping device 22, and bottleneck sealing block 2 is pressed between bottleneck and the stretching bar 1, with the gap between sealing ring 21 airtight bottleneck sealing blocks 2 and the stretching bar 1, overflow to stop air-flow, guider 23 can guarantee the to stretch direction of motion of bar 1 is accurate, then, conflict the bottle embryo on the mould at the bottom of the bottle in the upper end that makes stretching bar 1, at this moment, can allow air-flow flow into by the endoporus 31 of connecting rod 3, and entering in the hole 11 of stretching bar 1 inside by stretching bar 1 radial direction through hole 13 with its junction---sealing ring 33 can avoid gas to overflow from the stretching bar 1 and the junction of connecting rod 3, flow into the bottle embryo by the equally distributed some radial direction through hole 12 in stretching bar 1 upper end again, thereby produce uniform gas pressure on bottle embryo inwall, the bottle indusium is along radially evenly stretching, and the wall thickness after its moulding is also very even, yield rate can be significantly improved when therefore, adopting the utility model blown bottle; Because air-flow enters a bottle embryo from the equally distributed radial direction through hole 12 in stretching bar 1 upper end, thereby the influence of gap length is very little between air-flow tension boom 1 and the bottle embryo, thereby can do more the diameter of stretching bar 1 to improve the intensity and the service life of stretching bar 1, and can avoid the distortion of bar 1 that stretches, and then the rate of can significantly reducing the number of rejects and seconds; And after the intensity of stretching bar 1 improved, during with the bottle of the utility model blowing bottle or especially big, extra-high-speed, yield rate was still very high, thereby can widen range of application greatly.
