As China Patent No. a kind of container blowing machinery disclosed in the patent of ZL200680022059.4 bottle blowing fluid flow Control Component and there is the equipment of this assembly, it is compared with traditional blow-forming facility, effectively can reduce the size of dead volume, thus the electric energy that can reduce to a certain extent spent by compression pump, and improve the production efficiency of bottle blowing machine, but it still has deficiency, reason is: the drive unit controlling the blowpipe lifting of blow-forming facility is primarily of directly or be indirectly arranged on the guide wheel at blowpipe top by connector, and form with the cam that guide wheel matches, and, in order to ensure that guide wheel can against the non-orbiting scroll of the end face of cam, need the spring be set with on blowpipe can impose downward active force to blowpipe, to make guide wheel can according to the predetermined orbital motion of cam, in this case, just need the length additionally adding blowpipe, with mounting spring, thus add blowpipe internal capacity, be unfavorable for the minimizing of dead volume.
Summary of the invention
The object of the present invention is to provide a kind of lifting drive of bottle blowing machine blowpipe, it in blowpipe mounting spring, need not contribute to the length shortening blowpipe, thus reduces the internal capacity of blowpipe, dead volume can be made less.
The lifting drive of blowpipe of the present invention, comprise directly or be arranged on the guide wheel at blowpipe top by Connection Block, and the cam be fixed in the frame of bottle blowing machine, above the corresponding cam of the frame of bottle blowing machine, be also provided with limit cam, the gap between cam and limit cam forms the track matched with guide wheel.
The present invention owing to being provided with limit cam above the corresponding cam of frame, when guide wheel is along the orbital motion formed between cam and limit cam and in the process driving blowpipe to be elevated, guide wheel is under the restriction of the basal surface of gravity and limit cam, the track that can against the end face of cam rolls, and the length that additionally need not add blowpipe can impose the spring of downward active force to blowpipe with suit, therefore, after adopting the present invention, can blowpipe be done shorter, reduce the internal capacity of blowpipe, thus reduce corresponding dead volume value, to reduce the electric energy expended needed for compression pump, and improve the production efficiency of bottle blowing machine.
Accompanying drawing explanation
Fig. 1 is using state figure of the present invention.
Detailed description of the invention
As shown in Figure 1, the bottle blowing machine of indication of the present invention comprise frame (in figure, end represents), fixing can rotate with support 10 over the mount 10 cylinder body 20, being received in cylinder body 20 can the blowpipe 30 of the vertical movement of opposing cylinder 20, and the lifting drive that blowpipe 30 can be driven to be elevated, blowpipe 30 is led to by the compressed gas source of gas flow control assembly and at least one outside, at least one Compressed Gas discharge pipe and/or recovery tube, cylinder body 20 is stretched out in the top of blowpipe 30 and bottom, and bottom is provided with and can seals with bottle embryo (not shown) mouth the end socket 31 docked.
The lifting drive of blowpipe is then comprised directly or is arranged on the guide wheel 2 at blowpipe 30 top by Connection Block 1, and the cam 3 be fixed in the frame of bottle blowing machine, above the corresponding cam 3 of the frame of bottle blowing machine, be also provided with limit cam 4, the gap between cam 3 and limit cam 4 forms the track 5 matched with guide wheel.When guide wheel 2 to run and in the process driving blowpipe 30 to be elevated along the track 5 formed between cam 3 and limit cam 4, guide wheel 2 is under the restriction of the basal surface of gravity and limit cam 4, the track that can against the end face of cam 3 rolls, and the length that additionally need not add blowpipe 30 can impose the spring of downward active force to blowpipe 30 with suit, therefore, after adopting the present invention, can blowpipe 30 be done shorter, reduce the internal capacity of blowpipe 30, thus reduce corresponding dead volume value, to reduce the electric energy expended needed for compression pump (in figure, end represents), and improve the production efficiency of bottle blowing machine.
As shown in Figure 1, more steady for making blowpipe 30 be elevated, and it is more accurate to make blowpipe 30 be elevated displacement, slide block 6 can be set firmly on Connection Block 1, and set firmly the vertical guide rail 7 can installing slide block 6 over the mount 10, when guide wheel 2 rolls along track 5 and drives blowpipe 30 to be elevated, slide block 6 vertically vertical slip in guide rail 7, can ensure that blowpipe 30 steadily, is accurately elevated.
As shown in Figure 1, the fore-end 41 of the bottom surface of described limit cam 4 is the guiding curved surface that is upturned or guiding surface, when it can ensure guide wheel 2 with blowpipe High Rotation Speed, can successfully enter among track 5 that cam 3 and limit cam 4 formed.
Because guide wheel 2 and cam 3 are made by the steel of high rigidity, when guide wheel 2 runs along the track of cam 3 end face (be generally height rise and fall curved surface), there is shock to a certain degree in meeting and cam 3 end face, and, impact strength can strengthen with the quickening of the rotating speed of bottle blowing machine, and this shock can produce larger noise on the one hand, produce noise pollution; On the other hand, long-term work, can cause hard and crisp guide wheel 2 to occur cracking because of shock.As shown in Figure 1, for head it off, the external annular surface that can contact with cam 3 at guide wheel 2 arranges elastomeric layer, this elastomeric layer can be made of plastics, it effectively can cushion the shock between guide wheel 2 and cam 3, reduce noise, and improve the service life of guide wheel, certainly, also only elastomeric layer can be set at the end face of cam 3 and the bottom surface of limit cam 4, or elastomeric layer (not shown) be all set in the bottom surface of the external annular surface of guide wheel 2, the end face of cam 3 and limit cam 4 simultaneously.
