Description
Technical field:
The utility model relates to out band machine technology field, is used for cutting the power adjustments controller of the electrothermal tube on the cutter of driving the band machine of base band when producing printer color tape.
Background technology:
Drive the band machine in molten process of cutting; The height of temperature has crucial effects on the cutter head; And this temperature is to be produced by traditional heating wire coiling electrothermal tube, and this electrothermal tube temperature must produce the temperature that is higher than 500 degree and could satisfy the molten requirement of cutting of cutter head.
Tool bore on the cutter of driving the band machine that existing Britain produces can only be worn two electrothermal tubes, when voltage is low, just is difficult to satisfy produce needed temperature, and this just need heighten voltage.And can wear three electrothermal tubes through transformed cutter, and when wearing three electrothermal tubes, needing again like this voltage is reduced, this just needs that a device is installed and can easily voltage heightened, turn down.
The way that also can take the transformer pressure regulation is heightened, turned down to voltage, adopted the transformer pressure regulation just the resistive load of electrothermal tube to be become inductive load, molten again need be in opening the band process when cutting A.T.C at any time; And automatic temperature-controlled, equipment is mounted to be the intermittent controlled mode, because of this control mode; The instantaneous break-make of inductive load can produce bigger impact to power supply; So just possibly cause that gap opens, cause machine down, product rejection.Just have no idea to adopt transformer pressure regulation scheme based on such situation, and can only adopt electronics Power Regulation scheme.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And a kind of adjustment control of opening the electrothermal tube of band on the rounding machine cutter is provided; It had both reduced the power requirement to high-power silicon controlled rectifier; Can make the Power Regulation of can the step-down Power Regulation also boosting of this power regulation circuit again, satisfy in producing needs different capacity.
The technological solution of the utility model is following:
Drive the adjustment control of the electrothermal tube on the band rounding machine cutter; Comprise power circuit; Power circuit is made up of transformer, first diode, second diode, the 3rd diode, the 4th diode and electric capacity; Pulsating dc voltage after the 3rd diode, the 4th diode full-wave rectification is added on the operational amplifier through first resistance again, and operational amplifier produces the zero-crossing pulse signal and gives control chip, and control chip is given load according to zero-crossing pulse signal controlling bidirectional triode thyristor output power.
Said triode is electrically connected a high-current switch, and the controllable silicon of different flow is carried out big current trigger.
The beneficial effect of the utility model is:
1, it reasonably utilizes the operational amplifier detection function sensitive to input signal, has guaranteed the correct detection to zero crossing.Because the correctness of Detection Point, thereby make the trigger pip of output all begin to produce at zero crossing, this just guaranteed bidirectional triode thyristor lead can the time power supply almost do not impacted.Also harmonic interference is reduced to minimum limit.
2, adopt decade counter circuit CD4017 as the Power Regulation control circuit dexterously, it is succinct that such structure has circuit, and Power Regulation only needs through switch the output terminal of CD4017 reasonably to be made up the purpose that can reach Power Regulation.
3, power switch transistor does to isolate amplification to satisfy the needs of big current trigger in the usefulness; The way that power output adopts full-wave rectification and silicon control zero-cross pressure regulation output to combine; So both reduced power requirement to high-power silicon controlled rectifier; Can make the Power Regulation of can the step-down Power Regulation also boosting of this power regulation circuit again, satisfy in producing needs different capacity.
Description of drawings:
Fig. 1 is the circuit diagram of the utility model.
Embodiment:
Embodiment: see shown in Figure 1; Drive the adjustment control of the electrothermal tube on the band rounding machine cutter; Comprise power circuit A; Power circuit A is made up of transformer T, the first diode VD1, the second diode VD2, the 3rd diode VD3, the 4th diode VD4 and capacitor C; Pulsating dc voltage after the 3rd diode VD3, the 4th diode VD4 full-wave rectification is added on the operational amplifier CD through first resistance R 1 again, and operational amplifier CD produces the zero-crossing pulse signal and gives control chip IC, and control chip IC gives load according to zero-crossing pulse signal controlling bidirectional triode thyristor S output power.
Said triode Q1 is electrically connected a high-current switch K, and the controllable silicon S of different flow is carried out big current trigger.
Principle of work: control chip IC is used for zero-crossing pulse is counted and pulse distribution, thereby produces silicon controlled trigger signal, changes control chip IC counting mode through bidirectional triode thyristor S and regulates the power of AC load.For example, when bidirectional triode thyristor S was positioned at " 3 " shelves, control chip IC carried out quaternary counting, and 4 zero-crossing pulses of every input only produce 2 trigger pulses and go to trigger the bidirectional triode thyristor conducting, thereby these shelves are the half-power shelves.Provided 4 grades among the figure, control chip IC has 10 output terminals, and the combination that these output terminals are suitable just can obtain the different power shelves.Triode Q1 is connected into a high-current switch K, can carry out big current trigger to the controllable silicon S of different through-current capacities, thereby make it to work reliably.
