Description

Full-automatic preheating stretch blow molding machine

The utility model belongs to the plastic hollow forming machine.

Existing domestic and international two step method auto blow moulding machine, as Italian victory fly the machine of special company, Japanese FRONTIER INC machine, Chinese utility model patent " blow molding apparatus " (ZL93209757X), " blowing has the device of the plastic bottle body of internal tension " (ZL95224389X) etc., bottle base all is to adopt to carry bottle base than the complicated mechanical linkage from being heated to blow molding, machine is complex structure not only, energy consumption is big, and the requirement on machining accuracy height of machine components is answered and the machine cost costliness.

The utility model is at the shortcoming of prior art, design a kind of on platform, be provided with to move in the track to finish by a plurality of independent bottle base carriers automatically insert bottle base, preheating, stretch blow molding and take out that having of operation is energy-conservation, frame for movement is simple and reliable, easy to manufacture, and full-automatic preheating stretch blow molding machine with low cost.

For achieving the above object, adopt technical scheme as shown in Figure 1,, describe embodiment in detail below in conjunction with Figure of description:

Fig. 1: the full-automatic preheating stretch blow molding of the utility model machine plan structure schematic diagram;

Fig. 2: be A-A section among Fig. 1, the upset of expression bottle base pours into the structure cutaway view of carrier.

Fig. 3: be B-B section among Fig. 1, the expression bottle base is inserted in and is in the structure cutaway view that adds in the heat tunnel on the carrier;

Fig. 4: be C-C section among Fig. 1, bottle base and carrier are at the structural representation of blow molding station during the expression matched moulds;

Fig. 5: the full-automatic preheating stretch blow molding of the utility model machine cyclic transfer structural scheme of mechanism.

As shown in Figure 1, the full-automatic preheating stretch blow molding of the utility model machine by bottle base conveyer 1, bottle base permutation top send mechanism 2, add heat tunnel 3 cyclic transfer mechanism 4, stretch blow mechanisms 5, get bottle manipulator 6, stainless steel conveyer belt 7, switch board 8 form.Adopt stretch blow mechanism 5 and add heat tunnel 3, stainless steel conveyer belt 7 be arranged in parallel.Stainless steel conveyer belt 7 ends are by transverse passage-way 16 and add the connection of heat tunnel 3 arrival ends; Cyclic transfer mechanism 4 passes the connection of Stretch and Blow Mechanism 5 locked modes part annular and adds heat tunnel 3 ports of export, stretch blow mechanism 5, gets bottle manipulator 6, stainless steel conveyer belt 7.

Bottle base 9 is raise one by one by bottle base conveyer 1 and falls into bottle base permutation top and send in the access ramp 10 in the mechanism 2, utilizes the deadweight of bottle base and outstanding bottleneck circle, and bottle base 9 is suspended on the access ramp 10 one by one, forms a line under the effect of inertia.As shown in Figure 2.According to program, open a sluice gate cylinder 11 work, allow a bottle base slide into access ramp 10 ends, head into turning device 13 by top base cylinder 12 after, the bottle base mouth down falls into the carrier 14 of stainless steel conveyer belt 7 ends.Cylinder 15 top carriers 14 in horizontal top are pushed carrier 14 by straight push cylinder 17 and add heating bottle blanks 9 in the heat tunnel 3 in transverse passage-way 16.Therefore Figure 1 shows that the double mould cavity structure, two groups of parallel heat tunnels that add are arranged.As shown in Figure 3, carrier 14 is inserted on the bearing 20 in the round base 19 by the hollow metalwork 18 of band chain wheel to be formed, and is embedded with sealing ring 21 on the hollow metalwork 18, is used to seal the bottle base oral area.Under the drive of rotation chain 22, metalwork 18 produces rotation, bottle base 9 is rotated in adding heat tunnel 3 to be heated, thermal insulation board 24 and heating tunnel floor in heating board 23 lower ends all are equipped with cooling water pipe 26 25 times, be used for coolant carrier and bottle base neck, the pre-heat effect of bottle base 9 is effectively guaranteed.Push away carrier 14 in straight push cylinder 17 and enter and add heat tunnel 3 simultaneously,, the carrier 14 that adds the heat tunnel port is entered be fixed in the U type metalwork 28 that sends in cycles on mechanism's 4 chains 27, as shown in Figure 5 because carrier squeezes mutually and pushes away in the tunnel.After die sinking, motor 29 rotating link chains 27 and make carrier 14 in the U type metalwork 28 laterally enter throwing to blow mechanism 5.As shown in Figure 4, mould 30 clamps hollow metalwork 18 behind the matched moulds, and bottle base 9 is accurately located in mould 30, and end socket 31 upwards withstands hollow metalwork 18 lower seal, and 32 pairs of hot bottle bases 9 of stretching bar stretch and the inflation moulding.After the die sinking, motor 29 work move on to manipulator to carrier 14 and take out station, by getting the bottle 33 that bottle manipulator 6 takes out on the carrier 14.During machine operation, U type metalwork 28 is delivered to carrier 14 in the stainless steel conveyer belt 7 afterwards, because centrifugal action, carrier 14 breaks away from from U type metalwork 28, enters cooling in the conveyer belt 7, arrangement.After carrier 14 was sent to stainless steel conveyer belt 7 ends, according to program, bottle base 9 poured in the carrier 14, entered circulation once more.

As mentioned above, bottle base 9 is inserted in after permutation in the carrier 14 of stainless steel conveyer belt end, heads in the transverse passage-way 16 through horizontal top cylinder 15, is pushed to add rotate in the heat tunnel 3 by straight push cylinder 17 again and is heated.When straight push cylinder 17 pushes away carrier 14, the carrier 14 that adds heat tunnel 3 ports is squeezed in the U type metalwork 28 that is pushed on cyclic transfer mechanism 4 chains 27, cycle of rotation connecting gear 4 makes carrier 14 by cross drive stretching inflation moulding to the stretch blow mechanism 5.After the die sinking, cyclic transfer mechanism 4 is sent to carrier 14 gets a bottle station, by the bottle 33 on the manipulator 6 taking-up carriers 14.When rotating once more, carrier 14 breaks away from from the U type metalwork 28 of circulation transmission mechanism 4 and enters in the stainless steel conveyer belt 7 cooling, arranges, and waits for circulation once more.

Compared with prior art, the full-automatic preheating stretch blow molding of the utility model machine adopts a plurality of carriers 14 to carry to move in the setting track of bottle base 9 on platform to be finished slotting bottle base, preheating, stretch blow moulding and takes out operation, has the minimizing volume, energy savings, frame for movement is simple and reliable, advantages such as it is easy and with low cost to make, and control is convenient.
