Technical field
The present invention relates to a kind of bottle blowing machine, be specially the slideway structure of bottle blowing machine.
Background technology
At present, the slideway structure patent No. that the existing a kind of bottle blowing machine of applicant has double depanning is 200920117988.4, on the slideway of heating unit, be arranged with a plurality of push pedals of independently sliding of 1,2,3 or 4 row, in slip push pedal, there is bottle base fixture, on slideway, be provided with many group sliding cylinders and drive slip push pedal without bar electricity cylinder, the chamber number of corresponding preform mould is at every turn from the twice of heating unit bottle base quantity out, is provided with the circulation reach that many groups promote cylinders and realize slip push pedal without bar electricity cylinder on slideway.In bottle outlet unit, be normally provided with 4 cylinders and pass action, could realize the object of double depanning, a large amount of uses of air cylinder group, produce unnecessary passing action, cause the reduction of operating efficiency.
Summary of the invention
The object of the present invention is to provide a kind of bottle blowing machine slideway structure, on whole slideway structure, saved number of cylinders, reduce and pass step, improved operating efficiency.
A kind of slideway structure of bottle blowing machine, circulation slideway structure for semicircular tracks and straight rail composition, comprise embryo unit, heating unit, forming unit and bottle outlet unit, on slideway structure, be arranged with a plurality of push pedals of independently sliding, it is characterized in that: the extending part in semicircular tracks structure is provided with slip push pedal trough, one end, trough is provided with the anti-circular arc cylinder that pushes away, straight rail one end is provided with and pushes away straight line cylinder, the other end of straight rail is provided with pre-push cylinder, servo electric cylinder, motor, decelerator, the drive plate that moves forward and backward cylinder and can grasp slip push pedal, on drive plate, there is semi-circular grooves, drive plate is driven by servo electric cylinder, moving forward and backward cylinder retreats in order to promote the drive plate reach that moves forward and backward and then drive of servo electric cylinder.
On described straight slideway, be provided with push pedal gib block.
Described slip push pedal includes push pedal main body, wherein blow gun head, blow gun piston cylinder, guide bearing and swing pinion combination are fixed in push pedal main body, push pedal lower body part is provided with the fly out slide plate pad of slideway of anti-skidding push pedal, the bottom surface of push pedal main body contacts with slideway, on bottom surface, be provided with guide groove, guide groove and the corresponding cooperation of push pedal gib block arranging on straight rail.
The slip push pedal of arranging on described straight rail is that 1,2,3 or 4 rows are arranged side by side.
Semi-circular grooves on described drive plate is 2,4,6 or 8.
Adopt the slideway structure of said structure, in each circulation, the number of the preform mould that forming unit is corresponding is the twice of each heating unit from straight rail slip push pedal number out.For example, from straight rail slip push pedal out, be 1,2,3 or 4 at every turn, the number of the preform mould that forming unit is corresponding is so respectively 2,4,6 or 8.Because had the trough of slideway structure and the cooperation between slideway structure cylinder, save the passing step arranging on bottle outlet unit, simplified the structure of whole bottle blowing machine, improved operating efficiency.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, 2, 3, shown in 4, a kind of slideway structure of bottle blowing machine, circulation slideway structure 1 for semicircular tracks and straight rail composition, comprise embryo unit 10, heating unit 20, forming unit 30 and bottle outlet unit 40, on slideway structure 1, be arranged with a plurality of push pedals 2 of independently sliding, extending part in semicircular tracks structure is provided with slip push pedal trough 4, 4 one end, trough are provided with the anti-circular arc cylinder f that pushes away, straight rail one end is provided with and pushes away straight line cylinder g, the other end of straight rail is provided with pre-push cylinder a, servo electric cylinder b, motor c, decelerator d, the drive plate 5 that moves forward and backward cylinder e and can grasp slip push pedal 2, on drive plate 5, have semi-circular grooves 51, drive plate 5 is driven by servo electric cylinder b, moves forward and backward cylinder e and retreats in order to promote the reach that moves forward and backward and then drive drive plate 5 of servo electric cylinder b.
As shown in Figure 5,6, on straight slideway 11, be provided with push pedal gib block 12, described slip push pedal 2 includes push pedal main body 21, wherein blow gun head 22, blow gun piston cylinder 23, guide bearing 24 and swing pinion 25 combinations are fixed in push pedal main body 21, push pedal main body 21 bottoms are provided with the fly out slide plate pad 26 of slideway of anti-skidding push pedal, the bottom surface of push pedal main body 21 contacts with slideway, on bottom surface, be provided with guide groove 211, guide groove 211 and the corresponding cooperation of push pedal gib block 12 arranging on straight rail.Guide groove 211 is square, during in order to anti-skidding push pedal 2 front line slip, tilts.
As shown in Fig. 1,8,9,10, be the schematic diagram of an operation cycle of bottle blowing machine, in the present embodiment, the slip push pedal of arranging in straight rail is two rows.In the time of work, under original state, as shown in Figure 1, the semi-circular grooves that cylinder e promotes on servo electric cylinder b and drive plate 5 is blocked slip push pedal, motor c drives servo electric cylinder motion that the structural whole slip push pedals 2 of semicircular tracks are moved along semicircular tracks, make top four slip push pedals 2 be pushed into trough, trough 4 can just hold four slip push pedals, as shown in Figure 7.
Next push away two slip push pedal 2 backfills of arranging on straight line cylinder g promotion straight rail and postpone latter two room in four rooms that stay, pre-push cylinder a work pushes away stroke half, slip push pedal by just backfill on latter two room is to two rooms above, the simultaneously anti-first place that pushes away the slip push pedal backfill straight rail of circular arc cylinder f promotion trough, as shown in Figure 8.
Push away two last rooms of two slip push pedal 2 backfills that straight line cylinder g arranges on Work Promote straight rail again, as shown in Figure 9, move forward and backward cylinder e and promote servo electric cylinder band drive plate reach, drive plate 5 grips four slip push pedals 2 in backfill room, now get back to the state that circulation starts, enter do action again.
In each circulation, the number of the preform mould that forming unit is corresponding is the twice of each heating unit from straight rail slip push pedal number out.For example, from straight rail slip push pedal out, be 1,2,3 or 4 at every turn, the number of the preform mould that forming unit is corresponding is so respectively 2,4,6 or 8.Because had the trough 4 of slideway structure and the cooperation between slideway structure cylinder, save the passing step arranging on bottle outlet unit, simplified the structure of whole bottle blowing machine, improved operating efficiency.
