Detailed description of the invention
As shown in figs. 1 and 2, this pouring head includes main valve body 2, shaft 1, stirring-head 5 and stirs cover 6, shaft 1 is fixedly connected with the stirring-head 5 of below through main valve body 2, stirring-head 5 is positioned at and stirs cover 6, stirring-head 5 is just stirred the polyurethane material entering mixing at stirring cover 6 by the drive of shaft 1, polyurethane after stirring just flows out from the discharging opening of discharge head 7, is finally poured in footwear mould.
Enter the polyurethane material stirred in cover 6 to be expected to expect to flow into through main valve body 2 to mix with B by A, in main valve body 2, be provided with two the material feeding ducts identical with stirring cover 6 for this reason, AB material enters into through two material feeding ducts respectively and stirs in cover 6, and mixing in stirring cover 6, cast due to pouring head needs to control at any time, material feeding duct can not allow it be in circulation status always, for this reason, rotary valve axle 3 is also provided with in main valve body 2, this rotary valve axle 3 is simultaneously through material feeding duct, two, front and back, make beam duct be divided into charging hole 20 to arrange down with discharge opening 21(discharge opening 20, prevent material toward backflow), connecting hole 30 is provided with in rotary valve axle 3, as shown in Fig. 6 and 7, by rotating rotary valve axle 3, connecting hole 30 just can make charging hole 20 communicate with discharge opening 21 or cut off: when communicating, A material and B expect just can successfully flow through corresponding charging hole 20 simultaneously, connecting hole 30 and discharge opening 21 enter into and stir in cover 6, and when partition, because A material expects solidify in immobilising situation with B, want both and keep fluid state, both just must be allowed to be in flowing always, for this reason, the utility model is also provided with return port 22 on main valve body 2, and the rotation of rotary valve axle 3 is not that charging hole 20 is communicated (as shown in Figure 7) with discharge opening 21, make charging hole 20 communicate (as shown in Figure 8) with return port 22 exactly, such A material expects forever to be in flow regime with B.
The wall scroll material feeding duct that AB material is corresponding can meet cast requirement substantially, but need under special circumstances to accelerate cast efficiency, the utility model is provided with the second rotary valve axle 3 in addition in the side of rotary valve axle 3 for this reason, as shown in Figure 6, this the second rotary valve axle 3 is provided with front and back connecting hole 30 too, on main valve body 2, be also provided with the material feeding duct, two, front and back and return port of mating with this second rotary valve axle 3 in addition, wherein the discharge opening 21 in front two material feeding ducts communicates, and the discharge opening 21 in rear two material feeding ducts communicates; When rotating rotary valve axle 3 simultaneously, the A in front two material feeding ducts just can be made to expect to flow in stirring cover 6, meanwhile, rear two material feeding duct B material also flows to simultaneously and stirs in cover 6, certainly also can realize backflow simultaneously simultaneously.This mode not only increases cast efficiency, and such as when carrying some material feeding ducts of A material not circulate, the material feeding duct of another conveying A material then can use as preparation, thus greatly reduces the fault rate of pouring head, eliminates the trouble of many cleanings.Here also you need to add is that, two rotary valve axles 3 all drive rotation by cylinder 35, as shown in Figure 1, the expansion link of cylinder 35 is tooth bar 34, rotary valve axle 3 is provided with gear 33, and this gear 33 engages with tooth bar 34, rotary valve axle 3 just can be driven to rotate by the flexible of cylinder 35 expansion link.
As mentioned above, AB material enters into through discharge opening and stirs in cover 6, and compound does not at this moment have color, stir in cover to can individually the pigment in external paint box be incorporated into, the utility model is provided with colorant plate 4 between main valve body 2 and stirring cover 6, as shown in Figure 2, this colorant plate 4 has slotted eye 41, colorant valve opening and colorant charging aperture 40, wherein colorant charging aperture 40 communicates with colorant valve opening, colorant valve opening communicates with slotted eye 40, and slotted eye 40 and charging hole 21 and stir cover 6 and communicate, needle-valve 8 is provided with outside colorant plate 4, the needle 80 of needle-valve 8 is positioned at colorant valve opening, colorant charging aperture 40 just can be made to open or close by the flexible of needle 80.Adopt the mode that this pigment is external, just can when retaining A material or B material, realize by the needle-valve 8 controlling different pigment bucket correspondence the sole manufacturing different colours, not only increase the flexibility making different colours sole like this, also reduce unnecessary waste.
Pigment and AB material enter into stir in cover 6 just has stirring-head 5 to stir, be injected in footwear mould finally by discharge head 7, the rotation of stirring-head 5 is driven by shaft 1, shaft 1 realizes rotating by being connected with motor-driven, as described above, shaft 1 is through that main valve body 2 is fixedly connected with stirring-head 5, due to the constraint by machinery production technique, gap is certainly existed between shaft 1 and main valve body 2, and the compound stirred in cover 6 is easy to penetrate in gap, and then certain impact is produced on the work of shaft 1 and stirring-head 5.In order to solve this technical problem, the utility model adopts left-handed profile of tooth Design of Screw Thread 11 by shaft 1 with the close-fitting position of main valve body 2, and as shown in Figure 1, shaft 1 rotates, left-handed profile of tooth screw thread 11 just can suppress the compound up permeated, and finally makes material turn back to and stirs in cover 6.In addition, the bottom surface of the utility model stirring-head 5 is cambered surface 50, and on discharge head 7, be provided with the cancave cambered surface 70 matched with this cambered surface 50, as shown in Figure 5, by coordinating of cambered surface 50 and cancave cambered surface 70, the gap that stirring-head 5 and discharge head 7 can be made to coincide evenly, discharging residual volume is less, ensures that working environment cleans.
After having worked, pouring head needs cleaning, what first need cleaning is stirring-head 5, need stirring cover 6 to pull down when cleaning, conveniently remove and install, stirring cover 6 is removably installed in block set 61 by clamp system 60 by the utility model, and block set 61 is fixedly installed on colorant plate 4, as shown in figs. 3-4, clamp system 60 includes stirrup 601, two free ends of stirrup 601 have left and right fixture block 603 respectively, 604, wherein right fixture block 604 is connected with screw rod 602 one end, left fixture block 603 is placed on outside screw rod 602, screw rod 602 other end has been threaded gripping sleeve 600, block set 61 and stirring cover 6 are respectively equipped with adjacent annular protrusion, stirrup 601 just covers in two projections, by turning gripping sleeve 600, stirrup 601 just can be made to wale block set 61 tightly and stir cover 6, make both be tightly connected, or block set 61 is separated with stirring cover 6, stirring-head 5 is facilitated to clean.The part of cleaning is needed to be each through hole in main valve body 2 in addition, conveniently clean these through holes, charging hole 20 is communicated with external hole 201 by the utility model, as shown in Figure 7, this external hole 201 communicates with the space outside main valve body 2, and sealing is provided with seal 203 in external hole 201, when cleaning, as long as take out seal 203, because duct is through, cleaning up is also convenient; In addition, discharge opening 21 also connects clean-out opening 23, be provided with cleaning device 9 outside this clean-out opening 23, cleaning device 9 just can clean all through holes in main valve body 2 after injecting current.
