Description
Technical field
The present invention relates to a kind of bottle embryo heater of rotary bottle blowing machine, relate in particular to the heating chain position limiting structure of this bottle embryo heater.
Background technology
Rotary bottle blowing machine comprises two stations, and one is High Rotation Speed bottle blowing station, and one is the bottle parison heating station.Bottle embryo heating station is provided with rotating disk mechanism, heating chain, heating fluorescent tube, advances the embryo rotating disk, assists runner.Rotating disk mechanism comprises the power runner and holds the embryo rotating disk, the power runner with hold the embryo rotating disk and be arranged in same rotating shaft, rotating shaft one end connects motor.Rotated by the driven by motor rotating shaft, and then order about dial rotation.Advance the embryo rotating disk and be arranged in another root rotating shaft, rotating shaft one end connects motor.Advance the embryo rotating disk and hold the embryo rotating disk to be on same working face, the profile of tooth of advancing on the embryo rotating disk is identical with the profile of tooth on advancing the embryo rotating disk; Form the position relationship of tooth to tooth between the two in nearest each other place, and then form the zone of clamping bottle embryo between both tooth mouths.Heating chain is arranged on power runner and auxiliary runner, forms the annular of two ends curved, middle linearly section shape.Heating chain is movably connected with hinging manner by inner plate, outer plate by a plurality of Warming heads.
The heating fluorescent tube is positioned at the straightway place of heating chain, and is positioned at the both sides of heating chain.Heating fluorescent tube region is the thermal treatment zone of this bottle embryo heater.Heating chain is when entering the thermal treatment zone, and it can be subject to position-limiting action,, so that heating chain can not produce and rock at vertical direction, guarantees that simultaneously it also can keep balance in the horizontal direction.For arriving such technical purpose, available technology adopting installs roller additional in the inner plate both sides, and the center line of two rollers overlaps, and two parallel balance guide rails are set on frame, with the roller motion, realizes above-mentioned purpose on the balance guide rail.
Because balance guide rail 14 length are long, need to the part of segmentation be linked together by splicing, form rectangular balance guide rail.Balance guide rail 14 is plate construction, and this just provides planar structure for its end face, to be used for support roller 13.The track of this structure can be subject to processing technogenic influence and be non-level and smooth transition structure at the splicing position, as shown in Figure 1, when roller 13 from contact by the time can cause Warming head shake, make Warming head all produce and rock in vertical plane.Each segmentation is subjected to the impact of processing technology factor, also can have bending or other deviation, and Here it is makes Warming head not only in the splicing place generation at segmentation position, rock, and in other place, also can produce above-mentioned rocking.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of bottle embryo heater that suppresses heating chain rocks in vertical plane rotary bottle blowing machine.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: the bottle embryo heater of this rotary bottle blowing machine is provided with heating chain and locating part, described heating chain and locating part are flexibly connected, described heating chain comprises chain case and Warming head, described Warming head is movably connected in chain case, be movably connected by hinging manner between described chain case, the described chain case outside is provided with two limited rollers, described locating part is between two limited rollers, described limited roller is provided with the annular stop groove, and described locating part is provided with the protuberance of corresponding limited impression.
The present invention has abandoned in the prior art design principle of position-limit mechanism has been set in the Warming head both sides, adopts in the one-sided design principle that position-limit mechanism is set of Warming head.Locating part forms a kind of clamp position between the position-limiting tube wheel, namely limited roller is clamped in the locating part outside.After heating chain was installed, all chain cases all were in vertical state, and therefore two limited rollers are the position relationship that distributes up and down, and the chain case in the vertical direction is restricted, and obtains position-limiting action.On the limited impression of limited roller and locating part, protuberance has formed the mechanism that suppresses the chain case horizontal jitter jointly, can suppress thus heating chain rocking in horizontal plane.
