Description

Band turns to the bottle blank conveying mechanism of translating device

[affiliated technical field]

The utility model relates to the bottle base conveying device of blower for plastic bottle, and particularly a kind of band turns to the bottle blank conveying mechanism of translating device.

[background technology]

The automatic bottle blank conveying mechanism that uses on the existing blower for plastic bottle, as shown in Figure 1, comprise an endless glide 1, described slide rail has two or more right angles bend, but being installed on the slide rail, the bottle base seat 3 of some adjacent arrangements both can circumferentially move also rotation along slide rail, the cylinder propulsion plant 18 of corresponding right angle bend quantity respectively is equipped with at bend place in right angle on frame, and this cylinder propulsion plant respectively connects a clamp that can block the bottle base seat.The reciprocating action of two mobile synchronously drive clamps of cylinder propulsion plants makes corresponding bottle base seat turn over square position synchronously during work.When bottle base by after being located at one section drying tunnel on the slide rail and being heated to appropriate temperature, just (this shaped device is positioned on the shared straight way of two right angle bends to be blown to type when being pushed into bottle blow molding position, mold closing mechanism 20 is installed herein is used for air blowing processing bottle base), when being moved out of shaping station, make adjacent bottle base seat translation interlock again.By two cylinder propulsion plant reciprocating motions back and forth the bottle base seat on the endless glide is moved to the processing of shaping position bottle blowing one by one.This bottle blank conveying mechanism need be installed two cylinder propulsion plants respectively at diverse location, complex structure, and it is more to take up room, and the synchronous control technique of two groups of cylinder propulsion plants requires high, is difficult for holding.

[utility model content]

The technical assignment of the technical problems to be solved in the utility model and proposition is the bottle blank conveying mechanism complex structure that overcomes on the existing blower for plastic bottle, it is bigger to take up room, the demanding defective of synchronous control technique, a kind of designs simplification is provided, finish the bottle base seat with one group of push unit and turn to and move, control band easily turns to the bottle blank conveying mechanism of translating device.

The technical solution of the utility model is: band turns to the bottle blank conveying mechanism of translating device, comprise endless glide, place some bottle base seats of being with self-rotation wheel on the slide rail, the bottle base seat relies on slide rail mutually, it is characterized in that described endless glide is the slide rail with a right angle bend, is that the straightway slide rail of circular arc bend is provided with bottle base and turns to translating device for the right angle bend other end at one end.The utility model will have the endless glide of a plurality of right angles bend now and have only a right angle bend (all the other are the arc bend) instead, rely on bottle base to turn to translating device to make the bottle base seat change direct of travel (90 degree turn round) at right angle bend place, bottle base to be processed is pushed to the blow molding station; The mutually bottle base seat translation successively in slide rail that relies on, existing conveying mechanism is simple in structure, and it is little to take up room, and finishes the translation that turns to of bottle base seat with one group of push unit, moves reliable and stable.

Bottle base described in the utility model turns to translating device to comprise and is fixed on a tumbler and a translation part that moves on the seat side by side, tumbler and translation part outer end are provided with the arc bayonet socket, mobile seat is done unidirectional rectangular path relative to slide rail and is moved (move clockwise or counterclockwise, promptly do moving of parallel and far and near both direction relative to slide rail) under drive source drives.Turning to translating device once can drive two bottle base seats moves, the bayonet socket of tumbler and translation part outer end is used for the corresponding bottle base seat of clamping, move to the blow molding station when bottle base to be processed turns to the bottle base seat, the bottle base that synchronization has been blown shifts out the blow molding station with the bottle base seat.Move seat slide rail is far and near relatively and move the clamping of control tumbler and translation part and bottle base seat or separate, move seat and can realize that relative to parallel the moving of slide rail the bottle base seat turns to and translation, move and reach automatic continuous conveying bottle base by aforementioned aggregate motion.

Drive source described in the utility model comprises a drive track, push-and-pull cylinder and flat-removing air cyclinder, and the push-and-pull cylinder is connected in the drive track lower end, and flat-removing air cyclinder is connected in mobile seat one end; The drive track sidewall has gathering sill, and mobile seat is installed in can be along the gathering sill translation on the drive track.When flat-removing air cyclinder drives mobile seat along the gathering sill translation, can realize moving parallel move (cylinder stretching motion form bottle base seat stepping in slide rail move) of seat relative to slide rail; When the push-and-pull cylinder drives drive track relative to slide rail is far and near when moving, be installed on the drive track mobile seat and on tumbler, translation part, flat-removing air cyclinder move with drive track, realize moving seat and move relative to the distance of slide rail.

Be extended with pushing part on the bayonet socket of translation part described in the utility model.When the translation part shifts out a bottle base seat, pushing part is pushed the previous bottle base seat of adjacency simultaneously forward open, effectively enlarge the spacing of two bottle base seats, avoid because too small the causing of the adjacent spacing of bottle base seat blown good plastic bottle and touched mutually, the spacing demand that also can adapt to the heavy caliber bottle guarantees conveying mechanism running continous-stable.

Self-rotation wheel described in the utility model is a sprocket wheel, tumbler is provided with a holder, one guide rod is housed on the holder, be with compressing spring on the guide rod, convex shoulder and the holder that the guide rod outer end forms withstood at described compressing spring two ends respectively, and guide rod can insert when being in and stretching out between two sprockets on the sprocket wheel.The bottle base seat of laying bottle base to be processed is diverted part and blocks in the process of passing the blow molding station, be in guide rod elasticity between two sprockets that insert sprocket wheel under the compressing spring effect of stretching out the position and withstand sprocket wheel, the rotation of restriction sprocket wheel, make the bottle base on the bottle base seat keep static motionless, make things convenient on the blow molding station matched moulds processing bottle base.

The length of tumbler described in the utility model and translation part and arc bayonet socket are measure-alike, and the spacing of tumbler and translation part and bottle base seat turn to the distance of position and moulding position to be complementary.Measure-alike being convenient to of length and bayonet socket matches with the bottle base seat; Spacing and two stations are to guarantee to lay bottle base to be processed and turn to when moving to the blow molding station with the bottle base seat when one apart from matching effect, another bottle base seat shifts out the blow molding station together with the bottle base of having blown on it, so that the continuous stepping of the some bottle base seats on the slide rail is carried.

The utility model will have the endless glide of a plurality of right angles bend now and have only a right angle bend instead, what slide rail cooperated that one group of push unit can finish the bottle base seat turns to translation and continuously stepping, existing conveying mechanism is simplified, it is little to take up room, use reliable, convenient, the control operation performance greatly improves, and has overcome four jiaos and has been the defective that bottle base that circular arc slideway and two above right angle slideways exist is carried, turned to, and is applicable to that the bottle base of all size is carried.
