In view of above reason, the purpose of this utility model is to be difficult for buildup in order to provide a kind of exhaust performance good, to carry, and mixes, and plasticizing capacity is good, the product quality height, and production cost is low, the injection machine that energy consumption is low twin-screw melten gel injection device.
The utility model is with the improvement on single screw rod melten gel injection device at existing injection machine, it is characterized in that having place barrel be subjected to the twin-screw that oil motor drives (referring to Fig. 1～Fig. 4), twin-screw can be the kneading type and also can be non-kneading type, direction of rotation can be also incorgruous in the same way, for the plasticizing effect that obtains, screw rod is one or more snippets, and barrel can be monoblock type and also can be segmented.
Penetrate the platform guide shaft on the above-mentioned frame, penetrate platform and be loaded on and penetrate on the platform guide shaft, distributor box is loaded on to penetrate on the platform guide shaft and with injection cylinder and is connected, and the distribution transmission mechanism (referring to Fig. 1, Fig. 2) that is connected with twin-screw with oil motor is housed in the distributor box respectively.
The distribution driving shaft that is connected with oil motor is arranged in the above-mentioned distribution transmission mechanism, be loaded on the driving gear that distributes on the driving shaft, distribute driven shaft to be contained in the driven gear that meshes with driving gear, twin-screw is connected (referring to Fig. 2) with distributing driving shaft and distribution driven shaft respectively.
There is thrust axis to contract (referring to Fig. 2) on distribution driving shaft in the above-mentioned distribution transmission mechanism, the distribution driven shaft.
Exhaust outlet is arranged (referring to Fig. 3～Fig. 4) on the above-mentioned barrel.
Quantifying feed mechanism (referring to Fig. 5) is arranged on the above-mentioned hopper.
In the above-mentioned quantifying feed mechanism variable-speed motor is arranged, the decelerator that is connected with variable-speed motor, be loaded on the barrel on the hopper, place the feeding spiro rod that is connected with decelerator (referring to Fig. 5) in the barrel, motor drives feeding spiro rod by decelerator and rotates, the raw material helical feed that hopper is fallen reaches the purpose of control inlet amount by the rotating speed of regulating motor to twin-screw.
Observation window (referring to Fig. 5) is arranged on the above-mentioned hopper.
During work, raw material enters in the screw rod through hopper, barrel, oil motor rotates, power is delivered to the distribution driving shaft, again power is delivered to the distribution driven shaft by driving and driven gear again, two distributing shafts rotate and drive the two screw rods rotation, material positive displacement is advanced, the reaction force of material is in two screw rods, it is retreated and passes to thrust axis by two distributing shafts and contracts to make and distribute casing to retreat along penetrating the platform guide shaft simultaneously, the injection cylinder material required back pressure when fully plastifying of giving security simultaneously.When material reaches required amount, oil motor stops operating, the whole platform of penetrating is penetrated the platform guide shaft in the effect lower edge of penetrating the table oil cylinder and is moved forward, make nozzle touch mould gate, injection cylinder work done this moment, drive the motion that distributes casing to contract, distribute driving shaft, distribution driven shaft to inject forward and pass to two screw rods, the material that has plastified is injected in the mold cavity, just can produce injection-molded item and so forth by thrust axis.
The utility model adopts the mandatory conveying of twin-screw, is difficult for buildup, and venting quality is good; Because there are speed difference in spiral shell rib, the screw channel of twin-screw, so raw material is extruded betwixt and mills, material are mixed fully with mixing, self-cleaning property and rolling effect are good; The time that UPVC stops in twin-screw is short, and evenly, it is rotten to be difficult for localized degradation, the quality and the output of product are improved, and the composition of raw materials cost of UPVC is descended, and unit consumption can reduce, decrease machining cost, available UPVC powder directly is processed into various injection-molded items, and is applied widely.
