Description
Technical field
The utility model belongs to chemical fibre production facilities technical field, particularly relates to a kind of up-coiler that has the passive electromagnetic damper.
Background technology
In chemical-fibres filaments was produced, high-speed winder was one of formant that constitutes by spinning machine, played a part as-spun fibre and stretched and reel.Up-coiler is the key equipment in the chemical fibre spinning equipment, and technology relates to a plurality of subjects such as machinery, electrical control, Control Software, and its equipment investment accounts for 50%～60% of a whole set of chemical fiber machinery.Up-coiler is a high speed cantilever ingot axle, the ingot axle of high speed rotating at work, rotating speed is becoming in change, package quality and rigidity, external excitation is also becoming.Become vibrating system when therefore, the high-speed winder system belongs to a high speed rotary.In the package process, inevitably produce vibration, influence package quality.Increasing damping structure is a kind of common method that improves bobbin chuck high-speed cruising stationarity.The effect of damping can suppress amplitude, vibration is reduced and disappearance as early as possible.We know, increase the caoutchouc elasticity damping piece and form the vibration damping support in the structure of bobbin chuck, to reducing even eliminate the vibration of bobbin chuck, effect are clearly arranged.Find in long term studies with in using simultaneously,, apply static working current for traditional electromagnetic damper, will produce damping bigger, that can suppress rotor oscillation.Change the natural frequency that damping can change bobbin chuck, make it avoid the working speed scope as far as possible.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of up-coiler that has the passive electromagnetic damper, by changing the size control damping of quiescent current, change the natural frequency that damping can change bobbin chuck, make it avoid the working speed scope as far as possible, improve bobbin chuck high-speed cruising stationarity, improve package quality simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of up-coiler that has the passive electromagnetic damper is provided, comprise axle, white cover, fluid bearing and frame, the left end of described axle is connected with actuating device, axle is made up of left and right sides two parts, connect by a coupler interference fit between the two parts of the left and right sides, the axle of its left side section is thin than the axle of right-hand member section, right section axle is connected with white cover interference fit, described axle is by four fluid bearings, bearing seat and O type rubber ring by resilient mounting on frame, described four fluid bearings all are placed on the bearing seat, on the crust of described white cover outer end paper tube is housed, in the center of described left end axle, resilient mounting a passive electromagnetic damper.
Be wound with four independently coils on the described electromagnetic damper, two ends provide quiescent current with constant voltage power suspply in the winding of described coil.
The stator of described electromagnetic damper is to be formed by magnetic material silicon steel plate closed assembly.
In the process of winding head package, the actuating device of axle on the left side drives down and rotates, and drives the white cover that is connected right-hand member and rotates, and drives crust and paper roll then to rotate together, and silk thread is high-speed winding under the swinging of rabbit head.The electromagnetic damper of axle left end, its stator are to be formed by magnetic material silicon steel plate closed assembly, are wound with four independently coils on it.During normal operation, quiescent current by providing on the coil by constant voltage power suspply, produce magnetic field, when the axle whirling motion, all there is displacement in level and vertical direction, each piece electromagnet pole of electromagnetic damper and the air gap thickness between the axle have been changed, caused the variation in magnetic field, the variation in magnetic field causes producing on the magnet coil induced electric motive force again, electric current in the coil is fluctuation thereupon also, and consistent by the electric current that electromagnetic induction causes with the change frequency between the axle displacement, but have phase difference, thus produced damping.And control damping by the size that changes quiescent current, and by changing the natural frequency that damping changes whole bobbin chuck, make it avoid the working speed scope as far as possible, improve package quality.
Beneficial effect
The utility model can be by the control of quiescent current, and the pairing critical speed of natural frequency that makes bobbin chuck alleviates the vibration of bobbin chuck outside the working speed scope, improves bobbin chuck high-speed cruising stationarity, improves package quality simultaneously.
Description of drawings
Fig. 1 is a general illustration of the present utility model;
Fig. 2 is a passive electromagnetic damper scheme drawing of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As Fig. 1, shown in 2, the utility model comprises axle 5, white cover 3, fluid bearing and frame 2, the left end of described axle 5 is connected with actuating device, axle 5 is made up of left and right sides two parts, connect by a coupler interference fit between the two parts of the left and right sides, the axle of its left side section is thin than the axle of right-hand member section, right section axle is connected with white cover 3 interference fit, described axle 5 is by four fluid bearings 4,6,7,10, bearing seat 11 and O type rubber ring 1,8,9 by resilient mounting on frame 2, described four fluid bearings 4,6,7,10 all are placed on the bearing seat 11, on the crust of described white cover 3 outer ends paper tube is housed, in the center of described left end axle, resilient mounting a passive electromagnetic damper 12.
Be wound with four independently coils 15 on the described electromagnetic damper 12, two ends provide quiescent current 13 with constant voltage power suspply in the winding of described coil 15.
The stator 14 of described electromagnetic damper 12 is to be formed by magnetic material silicon steel plate closed assembly
In the process of winding head package, the actuating device of axle 5 on the left sides drives down and rotates, and drives the white cover 3 that is connected right-hand member and rotates, and drives crust and paper roll then to rotate together, and silk thread is high-speed winding under the swinging of rabbit head.When the axle whirling motion, all there is displacement in level and vertical direction, each piece electromagnet pole of electromagnetic damper and the air gap thickness between the axle 5 have been changed, caused the variation in magnetic field, the variation in magnetic field causes producing on the magnet coil induced electric motive force again, and the electric currents in the coil 15 are fluctuation thereupon also, and the electric current that is caused by electromagnetic induction is consistent with the change frequency between the axle displacement, but there is phase difference, thereby produced damping.Air gap thickness during rotor eddy between electromagnet and the rotor changes in time, caused the variation in magnetic field,, the variation in magnetic field causes having produced in the magnet coil fluctuation of current again,, and the phase difference of fluctuation of current and rotor displacement has produced the shock damping action power to rotor.By adjusting quiescent current, make damping to change, thereby natural frequency that can change itself have tangible damping effect.Can obtain different experiment effects according to different magnetic circuit areas, wire circle, static air gap, as change quiescent current, adjust damping and change at 0.01 o'clock from 0.008, frequency can change 20 to 30Hz, be enough to make the pairing critical speed of natural frequency of bobbin chuck outside the working speed scope, damping effect is obvious, improves package quality.
