Description of drawings
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is that the utility model is installed on the structural representation in the baking line machine;
Fig. 2 circuit theory of the present utility model.
Embodiment
Referring to Fig. 1,2, a kind of control device that is used to dry by the fire on the line machine, comprise power supply unit 20 and the electric motor fan control module 21 that is connected with power supply unit, temperature control unit 22, described temperature control unit comprises temperature-sensitive unit, amplifying unit, comparing unit and performance element.Present embodiment baking line machine is conventional baking line machine, is provided with electric motor fan 31 in the baking line machine support 30, is articulated with warm-air pipe 33 on the support tube of erectting on the support 32.The described temperature-sensitive unit that is arranged on the control device on the baking line machine adopts negative tempperature coefficient thermistor NTC, and negative tempperature coefficient thermistor NTC 36 is arranged on the upper end away from air outlet of baking line machine warm-air pipe.Present embodiment adopts thermistor to come temperature sensor, and in fact common temperature-sensing elements such as Chang Yong thermopair, infrared ray can be used for detecting the temperature in the warm-air pipe.
The signal that negative tempperature coefficient thermistor detects is delivered to amplifying unit by lead and is amplified.Amplifying unit and comparing unit are arranged in the baking line machine support, described amplifying unit is made up of amplifier U1C, be connected with feedback resistance R10 between the output terminal 8 of amplifier U1C and the negative input 9, the negative input of amplifier U1C is by resistance R 9 ground connection, and described negative tempperature coefficient thermistor NTC is connected to the positive input 10 of amplifier U1C.
The output signal of amplifier U1C is transported to comparing unit and setting value compares.Comparing unit comprises comparer U1D, and the negative input of comparer U1D 13 connects adjustable resistance RP1, just dries by the fire the line machine and need dry by the fire the hot blast temperature that and provided by adjustable resistance RP1.The positive input 12 of comparer U1D connects the output terminal 8 of amplifier U1C by resistance R 11.The setting value that temperature signal and its negative input 13 obtain in the warm-air pipe that the positive input 12 of comparer U1D obtains relatively back is exported to triode Q4 by its output terminal 14, controls ending or conducting of triode Q4.
The output terminal 14 of comparer U1D is connected to the base stage of triode Q4 by resistance R 12, and the emitter of triode Q4 connects the trigger electrode of bidirectional triode thyristor Q6, and the output stage of bidirectional triode thyristor Q6 is connected with the interface P2B of performance element heater.Heater 34 is arranged in the warm-air pipe, and thermofin 35 also is set between hot blast tube wall and the heater.Thermofin can be able to prevent warm-air pipe body wall temperature height and scald the user.The heater of present embodiment has two groups, and one group is passed through interface P2A connection, and another group connects by interface P2B, and the heater of interface P2A connection just begins heating when drying by the fire the work of line machine energized.Control by this device and connect heater by interface P2B.
Electric motor fan in the present embodiment is arranged in the baking line support, and the work of electric motor fan is controlled by bidirectional triode thyristor Q7.K switch 1 is closed and is had no progeny, though heater stops heating; But the interior remaining heat of warm-air pipe this moment is still very big, and temperature is also very high; For safe in utilization, these remaining heats are shed as early as possible.For this reason, designed by amplifier U1A and U1A etc. and formed the delay switching-off function.Close when K switch 1 and to have no progeny, U1A export noble potential, and capacitor C 3 begins charging, when the voltage that is recharged when electric capacity is higher than the A point voltage, U1B output electronegative potential makes triode Q5 by, with bidirectional triode thyristor Q7 shutoff, blower motor just quits work.Therefore, after turn-offing heating unit power, the blower motor endure regular hour (duration of charging of capacitor C 3), just remaining heat dissipates rapidly in the warm-air pipe, effectively raises security.
When the baking line machine that has this control device is started working, the heater heating that electric motor fan rotates, interface P2A connects, electric motor fan is outside the hot blast discharge pipe of being warmed by heater in the warm-air pipe.Hot blast temperature in the while negative tempperature coefficient thermistor NTC induction heat airduct, compare at comparing unit and set temperature value through amplifying the back, if the temperature value of actual measurement is higher than setting value, just observed temperature is lower, then triode Q4 conducting, the trigger electrode of connecting bidirectional triode thyristor Q6 simultaneously makes interface P2B connect the heater heating, thereby the temperature in the rising warm-air pipe makes that drying by the fire the hot blast temperature that also raises.Otherwise when observed temperature was higher, bidirectional triode thyristor Q6 turn-offed and to make interface P2B connect heater to stop to generate heat and reduce temperature in the warm-air pipe.
Present embodiment dries by the fire the size that hot blast temperature is controlled warm-air pipe internal heat generation body thermal value by the actual measurement warm-air pipe, and it is more accurate to make that baking line machine dries by the fire the hot blast temperature that, and has effectively improved the craftmanship of baking line machine.
Four amplifier U1A, U1B in the present embodiment, U1C, U1D also can adopt an integrated chip to replace, and for example adopt the LM324 cake core, and it is simpler to make that circuit constitutes.
It more than is specific embodiment of the utility model, but it is not in order to limit the utility model, any those skilled in the art, the displacement of the equivalent assemblies of under the prerequisite that does not break away from design of the present utility model and scope, having done, thus for example adopt other temperature-sensing element (device)s such as thermopair or infrared ray to the temperature at baking line machine warm-air pipe place detect the back to heater control change hot blast temperature that warm-air pipe blows out all should belong to the category that this patent is contained.
