Description

Automatic transport heating stretch blowing machine

The utility model relates to the process equipment of plastic containers, and the bottle base that particularly relates to after the injection moulding heats the equipment of stretch-blow automatic transport moulding.

With the polyester is raw material, through annotating, draw, blow the processing hollow plastic container, as Coke bottle, mineral water bottle etc.Produce the equipment of above-mentioned plastic containers, different with its structure, can be divided into injection moulding, the heating of fully automatic forming machine and substep processing, stretch blow split equipment.So-called fully automatic forming machine promptly enters to formed product from raw material and all finishes automatically on a machine, comprises the whole process of injection and stretch-blow, and as Chinese patent 86104834.2, name is called " injection stretching blow molding machine ".The characteristics of such machine are the production efficiency height, and operating personnel are few, production assurance.But the shortcoming of its existence is a complex structure, and manufacture difficulty is big, costs an arm and a leg, and is suitable for large enterprise and uses.The split equipment that so-called injection moulding, heating, stretch blow are processed step by step promptly becomes bottle base by injection machine with feed injection, bottle base is placed on the heater heats then, the bottle base drawn blow moulding machine stretch blow moulding after the heating.As Chinese patent 88221296.6, name is called " equipment of producing plastic containers ".The characteristics of this kind equipment are simple in structure, the bulk-breaking manufacturing, and the injection machine highly versatile can disperse to produce bottle base; Firing equipment is various informative; The stretch blow body is long-pending little, easy to manufacture.But the shortcoming of its existence is the per pass operation error is arranged, the percent defective height, operating personnel are many.

The purpose of this utility model is to overcome the existing existing defective of split equipment, and the equipment of a kind of bottle base heating and stretch-blow automatic moulding is provided.

The technical scheme of the utility model automatic transport heating stretch blowing machine is: a frame is arranged, the bottle base supporting conveying mechanism of bottle base heater, stretch-blow mechanism and shuttling movement is installed on the frame, it is characterized in that so-called conveying mechanism is by guide rail and driving wheel, driven pulley looping body, pitch chain around the ring body operation, roller is installed at connecting axle two ends at each pitch chain, roller matches with guide rail, and the bottle base supporting base is installed in the pitch chain.Bottle base heater and stretch-blow mechanism are installed on the ring body track.

Automatic transport heating stretch blowing machine of the present utility model, the lower guideway of its ring body is the mixing shape of arc or linear or arc and straight line, pitch chain is attached on the guide rail, the two ends of guide rail and driving wheel and driven pulley interference fits.

Automatic transport heating stretch blowing machine of the present utility model, at calibration eccentric wheel of side connection of driving wheel, the calibration eccentric wheel links to each other with power by transmission mechanism.

Automatic transport of the present utility model heating stretch blowing machine, at the parallel installation chain with guide rail of the inward flange of bottle base heater, chain matches with gear in the bottle base supporting shaft.

Automatic transport heating bottle stretch blowing machine of the present utility model; its so-called stretch-blow mechanism is made up of clamping mechanism and Stretch and Blow Mechanism; clamping mechanism is positioned at the top of upper rail, and Stretch and Blow Mechanism is positioned at the below of upper rail, the bottle base supporting base in the pitch chain with bottle base by between the stretch blow mould.

The utility model discloses a kind of automatic transport and finish bottle base heating back by stretch blowing machine machine-shaping, existing split equipment bottle base heater and stretch blow machine are combined on the frame, the bottle base that has omitted after needing manually will heat in processing is step by step taken between the stretch blow mould from heater, reduce operating personnel, particularly can guarantee product quality; The major part of architecture advances is that above, lower guideway or sliver and driving wheel and driven pulley are formed ring body, one group of pitch chain drives the bottle base supporting base and moves around ring body, pitch chain is different from chain etc., and bigger deadweight is arranged, so lower guideway straight line not necessarily, available arc, perhaps stage casing straight line and two or be arc by of driving wheel, pitch chain all can be attached on the guide rail, and it is simple, compact that compared with the prior art this structure has, reliable, installation, operation, characteristics such as easy to maintenance.

Below in conjunction with Fig. 1-Fig. 5 embodiment of the present utility model is done detailed explanation.

1, driving wheel; 2 ", 2 ' upward lower guideways; 3, pitch chain; 4, pitch chain coupling spindle; 5, roller; 5 ', the roller baffle ring; 6; Mandrel; 7, gear; 8, driven pulley; 9, bottle base supporting base; 10, bottle base; 11, bottle base heater; 12, clamping mechanism; 13, Stretch and Blow Mechanism; 14, hollow container; 15, calibration eccentric wheel; 16, transmission mechanism; 17, index hole; 18, pressure ring; 19, stretch blow mould; 20, locked mode bar; 21, locked mode cylinder; 22, infrared ray heating tube; 23, support; 24, lifting regulating mechanism; 25, chain.

The utility model relates to the equipment of producing hollow plastic container, and an overall frame is arranged, with driving wheel 1, driven pulley 8 and lower guideway 2 ', " the looping body, main combiner is installed on the ring body track upper rail 2.Form conveying mechanism by pitch chain 3 for one group, link to each other by coupling spindle 4 between each pitch chain 3, coupling spindle 4 two ends have roller 5 and baffle ring 5 ', roller 5 rolls on guide rail, baffle ring 5 ' play the guiding role is so guide rail also can claim sliver.Bottle base supporting base 9 is installed on the pitch chain 3, mandrel 6 and gear 7 are arranged, this gear 7 is to be cooperated by chain 25 by heater 11 time, plays even heat effect.Bottle base 10 is pacified to bottle base supporting base 9 at driven pulley 8 positions, entering heater 11, is thermal source by infrared ray heating tube 22 generally, and can install on both sides bottle base is heated, sometimes according to the bottle base needs, can adjust heating tube height etc. by lifting regulating mechanism 24.Bottle base 10 after the heating enters between the stretch blow mould 19, stretch blow processing at every turn can 2,3, but need shuttling movement to be interrupted when entering stretch blow, so the calibration eccentric wheel 15 that connects driving wheel 1 is set, can be by what of eccentric index hole 17, divide the anglec of rotation, determine stroke, calibration eccentric wheel 15 connects power by transmission mechanism 16.With two locked mode cylinders 21 of symmetry, drive mould 19 by locked mode bar 20 grades, and Stretch and Blow Mechanism 13 is below, locked mode machinery 12 is up.Hollow container 14 after the moulding continue by pitch chain drive around driving wheel 1 forwarded to below horizontal after, container breaks away from supporting base under the effect of deadweight, do not need blanking mechanism.Pitch chain 3 for fear of throwing off driving wheel and can entering guide rail smoothly, can be installed pressure ring 18 when passing through the periphery of driving wheel 1.
