The existing accompanying drawings course of work of the present utility model.At first see also Fig. 3, state when diagram pressure detector 24 stops to carry for the plastics forming material is in, this moment, piston 2402 was in a high position by spring 2406 pushing and pressing, communicate with gap delta between the bore 2411 by piston 2402 peripheries between the last interface 2412 of bore 2411 and the lower interface 2413, thereby air pressure P1 and external pressure P0 balance in the material carrier pipe 23, be atmospheric pressure.See also Fig. 2 again, when material capture device 11 clearancens of injection machine 10 need add the plastics forming material, level-sensing device 12 on this material capture device 11 is carried control panel 31 to send by the air of cable on trend air transport device 30 and is required to supply with signal, this air carries control panel 31 to start air transport device 30 immediately, promptly by air suction tube 32 suction air in material capture device 11, plastics forming materials A and B under the air-flow effect in the material feeding apparatus 20 just are admitted to material capture device 11 by material carrier pipe 23 to blower fan 34.See also the state diagram that Fig. 4 pressure detector 24 starts again, just having formed in material carrier pipe 23 when blower fan 34 starts and having carried the necessary flow velocity of plastics forming material is the air stream of 20-25m/sec.According to hydromechanical principle, above-mentioned air stream will cause the air pressure P1 in the material carrier pipe 23 to descend and be lower than atmospheric pressure, so the air pressure P1 in lower interface 2413 place's material carrier pipes 23 of pressure detector 24 and the external pressure P0 at last interface 2412 places have produced pressure reduction, i.e. P1＜P0.Under the effect of above-mentioned air pressure difference, outer gas stream flows into material carrier pipe 23 by gap delta, and piston 2402 is pushed and moves downward simultaneously, thereby piston 2402 enters tight state of contact with body 2401, and in whole plastics forming material course of conveying, this state is all remaining.Piston 2402 mobile its inner magnet 2404 that driven in bore 2411 is synchronized with the movement, the mobile induction of magnet 2404 has also triggered magnetic force proximity transducer 2405 in the sensor body 2403, make magnetic force proximity transducer 2405 draw wiring by it and send material supply control signal to material supply control panel 21, the control panel of material supply subsequently 21 synchronous 22 couples of plastics forming materials A and B by the feed bin outflow of material dispenser apparatus that start make metering-type supply, quantitative supply respectively or decide the volume type supply.If will make adjustment, then only need to move the position of adjustment slide block 2407 on sensor body 2403 and get final product the critical air difference force of passing piston 2402 actions.
After material is filled it up with in the material capture device 11, level-sensing device 12 will be carried control panel 31 to send to air and require stop signal, this air carries control panel 31 to close blower fan 34, the plastics forming material is carried thereby is stopped, air-flow in the material carrier pipe 23 disappears, air pressure P1 wherein returns to normal and equates with external pressure P0, because material carrier pipe 23 inside and outside draught heads disappear, piston 2402 sets back being pushed under the effect of spring 2406 elastic force, its motion causes magnet 2404 to trigger magnetic force proximity transducer 2405 again, make it to supply with control panel 21 and send the OFF control signal to material, material is supplied with the metering-type supply that control panel 21 stops 22 pairs of plastics forming materials A of material dispenser apparatus and B synchronously subsequently, perhaps quantitative is supplied with, and perhaps decides volume type and supplies with.
Plastics forming material conveying device described in the utility model has adopted special pressure detector 24 that can perception material delivery air to replace holding wire S to send immediately and transmit the supply enabling signal, thereby save a large amount of wire cables, thereby having reached the beneficial effect of simplifying installation, reducing cost, it can be applied on all kinds of injection machines.
