Detailed description of the invention
Fig. 1 is the working principle of the invention figure；
Fig. 2 is circuit diagram of the invention.
Specific embodiment
For make to make the present invention it is further understand, referring to Figure of description and specific embodiment to the present invention make into
One step explanation:
As depicted in figs. 1 and 2, a kind of tension control system of the take-up applied to glass-coated microwire wire drawing machine, including with
The take-up frequency converters that the stretching motor of wire drawing machine was connected stretching frequency converter, is connected with the take-up motor of wire drawing machine.It stretches
It is connected between frequency converter and take-up frequency converters by control circuit, take-up frequency converters are connected with tension sensor, tension sensing
Device is the tension swing rod potentiometer on the tension swing rod being mounted between the leading-out terminal of wire drawing machine and take-up end.Take-up frequency converters connect
It is connected to linear velocity potentiometer, which is used to detect the linear velocity of wire.Tension sensor is for detecting output
The tension signal and feed back input of wire are to take-up frequency converters, after this feedback quantity is carried out operation compensation by take-up frequency converters, with
The current sync speed of take-up motor is overlapped, and the output frequency for stretching frequency converter is adjusted, and controls take-up motor
The opposite wire vent linear velocity for stretching motor of revolving speed reaches synchronous.Then take-up frequency reduces tension greatly, and the small then take-up frequency of tension increases
Height keeps constant wire tension.When it is implemented, the conversion frequencies for stretching motor are believed by the analog quantity of linear velocity potentiometer
Number given, the frequency signal of take-up frequency converters is made of two parts superposition, and wherein first part is given by the stretching motor
The coil diameter of frequency signal and the wire currently exported determines, tension signal that second part is fed back by tension swing rod potentiometer
PID is to adjust to obtain.
Specifically, the system stretches the frequency conversion of motor M1 to stretch motor M1 as active force referring to circuit theory Fig. 2
Frequency is given by linear velocity potentiometer analog signals.Take-up motor M2 carries out tension force, is stretching line as system for tracking
The tension swing rod potentiometer installed between machine leading-out terminal and take-up end is received for detecting the tension of output wire as wire drawing
Thread tension signal feeds back to take-up frequency converters, take-up frequency converters by this feedback quantity by internal PID arithmetic and various compensation after, with
The current sync speed (analog input) of take-up motor M2 is overlapped, and the output frequency for stretching frequency converter is adjusted, to control
The opposite wire vent linear velocity for stretching motor M1 of take-up motor M2 revolving speed processed reaches synchronous, when tension is big, receives take-up frequency converters
Line frequency reduces, and tension hour improves take-up frequency, maintains wire tension constant.During take-up, take-up frequency converters
The coil diameter of winding can be calculated by relevant parameter setting automatically, keep the linear velocity of take-up synchronous with motor M1 is stretched,
The tension signal that PID controller built in take-up frequency converters feeds back tension swing rod potentiometer does operation and compensation adjustment, keeps
Retractable line tension is constant, when wire drawing machine starts, can smoothly start, and keeps not breaking when starting, production process tension is steady, wave
Dynamic very little.Coil diameter calculates in real time, and accuracy is very high, ensure that the torque of take-up motor output has good Lubricity,
The recursive operation that joined coil diameter when calculating coil diameter oneself can correct coil diameter to correct numerical value when operation error.Cause
Rotary inertia for wrap-up be it is very big, when coil diameter is changed from small to big.If operator accelerates, slows down, stopping, again
The phenomenon that quick-fried line and loose ends are easily caused when activation, the quality that will result directly in product is bad, and in above-mentioned various situations, it receives
The phenomenon that volume is all very stable, and tension is constant all the time, and quick-fried line and loose ends is not present.
In conclusion invention uses double frequency control, so that the highest operating linear velocity of glass-coated microwire wire drawing machine is reachable
2400m/min, and highly stable, the problem of completely solving unstable original takeup tension and low-frequency jitter, so that winding
Performance is more preferable, and breakage ratio is greatly reduced.Tension and swing rod of double frequency conversion wire drawing machines during whole service are just very steady always,
Even if starting and parking are without significant change, while improving device efficiency, having saved electricity consumption, and this system electric device is matched
Setting simple, cost, there are also biggish reductions compared with original.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and what is described in the above embodiment and the description is only the present invention
Principle, various changes and improvements may be made to the invention without departing from the spirit and scope of the present invention, these variation and
