Delay circuit can select the delay circuit being made up of for core 555 chips in the present embodiment, due to delay circuit
It has been be disclosed that, be prior art, it should be understood by those skilled in the art that its operation principle, will not be repeated here.
The course of work of control unit 5 is as follows：
When preheating device works, air exhauster 2 is less than rated speed, and air exhauster 2 is constantly by the casing 83 of rapid steamer 8
Water vapour is input into pre- hot-rolling 1 to maintain the temperature of pre- hot-rolling 1 by air inlet pipe 14, compensates pre- hot-rolling 1 and is preheated to fabric
During thermal loss；Motor 3 is in rated speed, and pre- hot-rolling 1 by fabric during casing 83 is delivered under this rotating speed
It is a predetermined value with the time of contact of fabric.
Because the water vapour that air exhauster 2 is extracted is the water vapour in casing 83, its temperature is in fluctuation in certain limit, and
Because the difference of impressing pattern can make printing and dyeing feed distribution uneven on fabric, thus its heat absorption ability can difference, when it
The heat of pre- hot-rolling 1 can reduce temperature when absorbing heat very fast after being sucked away, and the temperature that temperature sensor experiences the surface of pre- hot-rolling 1 is less than
Measurement temperature signal is produced during predetermined temperature.
After the temperature on the pre- surface of hot-rolling 1 of temperature sensor measurement generate temperature measurement signal be transmitted in comparison circuit 51 and with ginseng
The numerical value for examining voltage signal is compared.Due to temperature it is higher when, the numerical value of temperature measurement signal less than reference voltage signal numerical value,
Comparator export low level, through with door And1 after still be low level, now triode Q1 be not turned on.The armature circuit of air exhauster 2
In, the voltage that resistance R6 divides is rotated big under the armature voltage of air exhauster 2 is smaller, thus air exhauster 2 is in low speed；Similarly
Rated speed is in motor 3.
After temperature drop to uniform temperature, the numerical value of the temperature measurement signal of temperature sensor output is more than reference voltage signal
Numerical value, comparator output high level is input to delay circuit I, and time delay is exported after T1 for a period of time, defeated with comparing instantly afterwards
Go out with rear output, if instantly comparing output still be high level, with door AND1 export control OFF signal one be high level, conducting
Triode Q1, relay KM1 obtains electric, inner-core adhesive armature S1, resistance R5 is parallel on resistance R6, total outer meeting resistance
Resistance diminish, electric current becomes big in circuit, and the voltage that it is got reduces, and the relative armature voltage of air exhauster 2 increase, rotating speed becomes
Hurry up, drive the blade of air exhauster 22 to rotate and a height of normal speed is risen by low speed, accelerate water vapour supply, make the temperature in pre- hot-rolling 1
Rise.
In comparator output high level simultaneously, in also entering into delay circuit II, time delay is exported after T2 for a period of time.Due to
T1 is less than T2, and air exhauster 2 accelerates in advance, accelerates, to the water vapour supply in pre- hot-rolling 1, to make the temperature in pre- hot-rolling 1 increase, if
That the temperature step-down of water vapour makes the temperature of pre- hot-rolling 1 to return to predetermined value, then by after the T2 times, delay circuit II
With comparing output and rear output instantly.If comparing output instantly is still high level, the control OFF signal exported with door AND2
Two is high level, and turn-on transistor Q2, relay KM2 obtains electric, and inner-core adhesive armature S2 disconnects normally-closed contact, resistance
R9 is disconnected from being parallel on resistance R10, and the resistance of total outer meeting resistance becomes big, the voltage that the resistance of total outer meeting resistance is got
The armature voltage of air exhauster 2 for becoming big, relative reduces, and rotating speed also has normal reduction, so that the rotating speed reduction of pre- hot-rolling 1, and then
Increase the time of contact of pre- hot-rolling 1 and fabric, pre- hot-rolling 1 is contacted with fabric within this time of contact carries out heat exchange, pre- hot-rolling 1
Can be by its rapidly pre-warming to predetermined temperature, so that surface temperature reduces steam pre- with to evaporate temperature closer after fabric preheating
The hot time.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model is not limited merely to above-mentioned
Embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.It should be pointed out that right
For those skilled in the art, some improvements and modifications under the premise of the utility model principle is not departed from,
These improvements and modifications also should be regarded as protection domain of the present utility model.
