Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
Embodiment one.
As shown in Figures 1 to 5, the preferred heater of a kind of bottle blowing equipment of the present invention, comprise annular delivery track 1 and drive sprocket 2, described annular delivery track 1 inside is provided with chain 3, described drive sprocket 2 drives chain 3 to rotate in annular delivery track 1 inner loop, described chain 3 is provided with rotating clamp body 4, and the lower end of described clamp body 4 is provided with rotating sprocket 41, and described delivery track is provided with the rotary-chain 42 driving described rotating sprocket 41 to rotate; The both sides of described annular delivery track 1 are provided with a bottle embryo heater 5, and described chain 3 is provided with the preferential heating arrangements 6 of bottle embryo.Bottle embryo 9 is installed on clamp body 4, chain 3 drives bottle embryo 9 annularly delivery track 1 cycle rotation, at rotation process, rotary-chain 42 drives rotating sprocket 41 to rotate, make bottle embryo 9 rotation on clamp body 4, bottle embryo heater 5 heats the bottle embryo 9 rotated, the preferential heating arrangements 6 of bottle embryo controls the heating surface of bottle embryo 9, short-axis direction wall 81 is made preferentially to heat and accept more heat, long axis direction wall 82 is made to add thermo-lag, reduce the temperature of heating, now bottle embryo 9 orthogonal short-axis direction wall 81 and long axis direction wall 82 form certain temperature difference, compensate the difference of bottle embryo 9 stretching distance in blow mold, make shaping after the uniform wall thickness of bottle.
The present invention starts with from the heating of bottle embryo 9, and plastics ductility is at different temperatures different.The ductility that temperature is high is large, the physical property that the ductility that temperature is low is little, when the heating design of heater, for the above-mentioned characteristic of plastics, in two vertical direction of bottle embryo 9 cross section, change the duration of heating and the temperature of heating, in the both direction of same bottle embryo 9, temperature is inconsistent.Heat many at the short-axis direction wall 81 of bottle embryo 9, heat at long axis direction wall 82 few.When 9 blow molding of bottle embryo, the short-axis direction in the horizontal chamber of bottle of blow mold from bottle embryo 9 apart from close to, stretching distance is short; The long axis direction in the horizontal chamber of bottle is from bottle embryo 9 distance, and stretching distance is long.Due to the difference of bottle embryo 9 temperature in the two directions, compensate the difference of distance in stretching, the plastic bottle 8 of the uniform wall thickness of final molding.
Particularly, the preferential heating arrangements 6 of bottle embryo of the present embodiment comprises baffle plate 61, and described baffle plate 61 is arranged at bottle between embryo heater 5 and chain 3, and described baffle plate 61 offers the diathermanous hole 62 of some short-axis direction walls 81 for heating bottle embryo 9.This baffle plate 61 can block bottle heat that embryo heater 5 distributes, heat is given out from diathermanous hole 62, heat the short-axis direction wall 81 of bottle embryo 9, the long axis direction wall 82 reducing bottle embryo 9 is heated, and bottle embryo 9 surface temperature is in the two directions made a difference.
As preferably, the width A in the diathermanous hole 62 of the present embodiment equals bottle embryo 9 in bottle embryo 9 rotation week age and to revolve round the sun with chain 3 1/4th of travel distance, and the width A in described diathermanous hole 62 equals the distance B between adjacent two diathermanous holes 62.The bottle embryo 9 of circle is divided into the quartering, also revolves round the sun while bottle embryo 9 rotation.Bottle embryo 9 rotate in the time of one week, chain 3 with bottle embryo 9 through twice diathermanous hole 62 and the baffle plate 61 between twice adjacent two diathermanous hole 62.When diathermanous hole 62, allow and be in two bottle embryo 9 surfaces on short-axis direction just to diathermanous hole 62, when baffle plate 61, be in two bottle embryo 9 surfaces on long axis direction just to baffle plate 61, thus cause bottle embryo 9 surface temperature in the two directions to produce difference.In baffle plate 61, the parameter in diathermanous hole 62 is not unique, by controlling speed and the orientation of the rotation of bottle embryo 9, and carries out segmentation block bottle embryo heater 5 is corresponding, bottle embryo 9 surface temperature in the two directions can be made to produce difference.
The rotary-chain 42 of the present embodiment is fixed on described annular delivery track 1 in closed loop.Bottle embryo 9 keeps rotating in transportation, is convenient to the speed and the orientation that control the rotation of bottle embryo 9.
As preferably, described bottle embryo heater 5 is positioned at the middle part of annular delivery track 1, and the segmentation being convenient to bottle layout of embryo heater 5 and baffle plate 61 is blocked.
Embodiment two.
As shown in Figure 6, the difference of the present embodiment and embodiment one is, the preferential heating arrangements of described bottle embryo 6 comprises preferential heater 7, and described preferential heater 7 is arranged at bottle rear end of embryo heater 5 and is positioned at the both sides of chain 3; Described rotary-chain 42 is distributed in and is provided with a bottle orbital segment for embryo heater 5.The bottle embryo 9 of this enforcement is when heating, first to whole bottle embryo 9 homogeneous heating, when bottle embryo 9 is heated to last one end distance, rotating sprocket 41 departs from rotary-chain 42, bottle embryo 9 on clamp body 4 stops the rotation, now bottle embryo 9 short-axis direction wall 81 is just to the preferential heater 7 of chain 3 both sides, and the short-axis direction wall 81 of preferential heater 7 to bottle embryo 9 heats simultaneously.Because bottle embryo 9 stops the rotation, heat many at the short-axis direction wall 81 of bottle embryo 9, in the direction of major axis, heating is few, makes bottle embryo 9 surface temperature in the two directions produce difference, the difference of distance during same compensation stretches, the plastic bottle 8 of the uniform wall thickness of final molding.
As preferably, the top of the bottle embryo heater 5 of the present embodiment is provided with heat shield 51, and described heat shield 51 is between bottle embryo 9 mouthfuls and bottle embryo heater 5.This heat shield 51, for stopping a bottle heat for embryo heater 5, is avoided heating bottle embryo 9 mouthfuls, is caused bottle embryo 9 mouthfuls distortion, affect the size of bottle embryo 9 mouthfuls.
The surface temperature difference that the preferred heater of bottle blowing equipment of the present invention is axially different to bottle embryo 9 regulates and controls, and makes bottle embryo 9 produce the temperature difference in the two directions, guarantees flat plastic bottle 8 uniform wall thickness of blowing.
The remainder of the present embodiment is identical with embodiment one, repeats no more here.
Above content is only preferred embodiment of the present invention, and for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, this description should not be construed as limitation of the present invention.
