(2) background technology:
What traditional all steel giant embryo meridian forming machine (calling tyre building machine in the following text) setting drum the blowing pressure adopted is pneumatic proportional valve, carries out aeration settling.
But the moment aeration quantity that the inflation of the setting drum of tyre building machine needs (is greater than 14M very greatly
3), terminal pressure requires again very little (more than 0.0 Mpa); And the power failure suddenly of some tire plant, blowing-out, causes the pressure of setting drum to ensure (have a power failure, after blowing-out, fall to press very fast), and the tire half an hour after sizing, will be crushed by deadweight, is out of shape, very large on the impact of tire quality.
(3) summary of the invention:
For this reason, the present invention proposes a kind of all steel giant embryo meridian forming machine setting drum pressure control device, its object is accurately to control the blowing pressure, and has a power failure at vulcanizer, while stopping the supple of gas or steam, ensures that tyre inner pressure does not leak.
Can realize the technical scheme of all steel giant embryo meridian forming machine setting drum pressure control device of above-mentioned purpose, comprise the valve control elements arranging corresponding to inflation gas circuit, described inflation gas circuit is communicated with source of the gas and the tire of shaping on setting drum, difference is, described valve control elements comprises air inlet film plate valve and exhaust membrane plate valve, described air inlet film plate valve and exhaust membrane plate valve are by connection PLC Programmable Logic Controller, and described PLC Programmable Logic Controller detects the pressure switch of tire internal gas pressure size by connection.
Operation principle of the present invention:
The conducting of PLC Controlled by Programmable Controller air inlet film plate valve is inflated tire on setting drum, the internal pressure that pressure switch detects tire reaches after setting pressure, detection signal is fed back to PLC Programmable Logic Controller, PLC control air inlet film able to programme plate valve stops inflation, if inside tires pressure exceedes setting pressure, PLC Controlled by Programmable Controller air inlet film plate valve stops inflation, and control exhaust membrane plate valve is opened and carried out exhaust; If after being detected by pressure switch when inside tires pressure leakage or other reasons cause pressure, detection signal feeds back to PLC Programmable Logic Controller, PLC Controlled by Programmable Controller air inlet film plate valve is inflated, until the pressure balance of tire.
A kind of set-up mode of described air inlet film plate valve and exhaust membrane plate valve, air inlet film plate valve is directly connected in inflation gas circuit, and exhaust membrane plate valve is by the inflation gas circuit after exhaust branch road access air inlet film plate valve.
Further be designed to, described inflation gas circuit is communicated with tire by the air inlet air flue of (central authority) elevating lever inside on setting drum.
The scheme that described pressure switch detects tire internal gas pressure size is that pressure switch is communicated with tire by detecting gas circuit.
Further be designed to, described detection gas circuit is opened in the inside of (central authority) elevating lever on setting drum.
Beneficial effect of the present invention:
1, all steel giant embryo meridian forming machine setting drum pressure control device of the present invention is simple in structure, and dismounting is easy to maintenance, and cost is low.
2, the present invention reduces difficulty of processing, and pressure controling precision is high, and inflation is fast.
3, the present invention is in the time stopping the supple of gas or steam, have a power failure, and the persistence of pressurize is higher than traditional proportioning valve.
4, the present invention is particularly suitable for the inflation requirements of large capacity tire.
