Fixed case 6 is stretched into the permanent magnetic plate 11 inside the magnetic regulator 8 inside fixed case 6 to be connected；The top of permanent magnetic plate 11 is magnetic
The energization magnetic sheet 10 for having difference in height with permanent magnetic plate 11 inside draught control mechanism 8, the magnetic regulator 8 is connected with resistance controller
7；The top of magnetic regulator 8 is connected with the adjusting screw 9 through fixed case 6；The bottom of fixed case 6, which is provided with, passes through monitoring activity
Bar 12 moves to adjust the displacement transducer 5 of the resistance of resistance controller 7；
The enamel-covered wire 3 extracted out in coiled strip 2 on damping wheel 1 passes sequentially through damping wheel 1, guide wheel 4, tensioning wheel 13, position-limited wheel
14, it is finally wound up on field spider 15, tensioning wheel 13 is adjusted by the resistance and/or adjusting screw 9 that adjust resistance controller 7
To the coiling forward pull of enamel-covered wire 3；
During coiling enamel-covered wire 3, the tension force of enamel-covered wire 3 is continually changing so that the motion bar being connected with tensioning wheel 13 is about 12
Motion, displacement transducer 5 detects the resistance of regulation resistance controller 7 after motion bar 12 moves up and down to adjust magnetic regulator
Electromagnetic force in 8, so that when adjusting the tensioning wheel 13 that is connected by motion bar 12 with magnetic regulator 8 to the coiling of enamel-covered wire 3
Tension force, realizes the constant of the tension force of enamel-covered wire 3.
The step of more detailed regulation 3 tension force 1 of enamel-covered wire and principle are as follows：
(1) coiling forward pull is presetting：Start control circuit power supply, resistance controller 7 obtains electric.Adjust resistance controller
7 resistance, obtains initial resistivity value R and initial current I.Initial current I gives electricity to the energization magnetic sheet 10 in magnetic regulator 8,
Finally made by motion bar 12 and tensioning wheel 13 so that producing initial electromagnetic power F1, the F1 between energization magnetic sheet 10 and permanent magnetic plate 11
With on enamel-covered wire 3, initial coiling tension force F2 is produced.If tension force F2 is still excessive or too small, not up to pre-set value, connect down
That goes has adjusted two kinds of selections again, and one is to continue with adjusting the resistance of resistance controller 7, untill obtaining satisfied F2；Two are
Turning adjusting screw 9, makes magnetic regulator setting height(from bottom) difference H change, H diminishes, and can widen energization magnetic sheet 10 and permanent magnetic plate
Gap between 11, F1 diminishes immediately, and F2 also diminishes therewith, and on the contrary then H2 becomes big, and F1 becomes big, and F2 becomes big.
(2) main power source is started, field spider 15 does uniform rotation under the driving of external impetus, and enamel-covered wire 3 is in rectangular shape
Form it is wound on field spider 15.Coiling radius is done between maximum radius R1 and least radius R2 during coiling periodically becomes
Change, while enamel-covered wire 3 continually bypasses four corners, so the coiling tension force F2 on enamel-covered wire 3 is in constantly changing.Work as enamel-cover
When the coiling tension force F2 of line 3 becomes big, enamel-covered wire 3 is oppressed motion bar 12 by tensioning wheel 13 and moved up, and displacement transducer 5 is supervised
Measure motion bar 12 to make upwards to be signaled to resistance controller 7 after positive position movement, resistance controller 7 increases resistance R,
So that electric current I reduces, electromagnetic force F1 is caused to reduce, so that the coiling tension force on enamel-covered wire 3 is quick again to initial setting
Tension value fall after rise；Conversely, when the coiling tension force F2 of enamel-covered wire 3 becomes small, electromagnetic force F1 promotes motion bar 12 to move down,
The motion bar 12 that displacement transducer 5 is monitored is made to be signaled to resistance controller 7, resistance control after moving for negative position downwards
Device 7 processed reduces resistance R so that electric current I increases, and causes electromagnetic force F1 to increase, so that the coiling tension force on enamel-covered wire 3 is quickly weighed
It is newly soaring to the tension value initially set, so go round and begin again, because the change in displacement of motion bar 12 is constantly rapidly fed back
To magnetic regulator 8, accordingly ensure that the substantially constant of coiling tension force.
