Specific embodiment
Below by the description to embodiment, the shape of for example related each component of specific embodiment of the present utility model
Shape, construction, the mutual alignment between each section and connection relationship, the effect of each section and working principle, manufacturing process and operation
Application method etc., is described in further detail, to help inventive concept of the those skilled in the art to the utility model, technology
Scheme has more complete, accurate and deep understanding.
As shown in Figure 1, a kind of tension control system for fly frame, including single-chip microcontroller, magnetic powder brake, controlled device
And tension detecting apparatus；The Tensity size information of tension detecting apparatus real-time detection controlled device feedback, and send information to
Single-chip microcontroller carries out processing in real time and obtains corresponding processing result, and is carried out accordingly according to revolving speed of the result to magnetic powder brake
It adjusts；Wherein, controlled device is reel for yarn 6.
As shown in Fig. 2, the utility model further includes traction roller 1, guide roller 2 and gear 7.Tension detecting apparatus is by dancer
3, connecting rod, cylinder 4 and potentiometer 5 form.Dancer 3 is mounted on the lower section of two guide rollers 2, and three is in triangular distribution, gas
Cylinder 4 is mounted on the underface of dancer 3, and one end of connecting rod is fixed on dancer 3, and the other end passes through gear 7 and potentiometer 5
Contact.
When 4 epicoele of cylinder accesses compressed air, the tension acted on film is that roller gravity vertical stress component and cylinder 4 hang down
The sum of straight active force.Since 3 pivot angle of dancer is smaller, vertical stress component is basically unchanged in swing process, therefore, is directly changed cylinder
4 pressure can adjust the tension of film, and Tensity size is unrelated with 6 diameter of reel for yarn.In winding process, when tension becomes
When change, dancer 3 is accordingly swung, and potentiometer 5 detects tension variation indirectly.
Preferably, potentiometer 5 is 360 degree of floating potential devices.
Tension detects in addition to the above process, and there is also with the feelings that 6 diameter of reel for yarn increases, 6 linear velocity of reel for yarn is constant
Under condition, process that angular speed is gradually reduced.Coiled material acts on gravity, the cylinder 4 of pulling force and roller itself on dancer 3 when beginning
Thrust balance each other, dancer 3 is in intermediate equilbrium position.With the increase of 6 diameter of reel for yarn, dancer 3 is swung up,
Potentiometer rotation is driven, feedback signal is made to deviate from former equalization point voltage value.The signal obtains compared with given voltage signal
Deviation after integrated operation, adjusts motor speed, declines the revolving speed of motor, and the tension of coiled material is restored to given value, floats
Roller 3 is returned to original equilbrium position.With the increase of 6 diameter of reel for yarn in entire winding process, motor speed constantly into
Row adjustment saves membrane tension constant.
As shown in figure 3, magnetic powder brake by armature spindle 11, front cover 12, labyrinth ring 13, rotor 14, magnetic yoke 15, coil 17,
The high and heat-resist magnetic powder 14 of rear cover 18, sealing ring 19, pole shoe 20 and magnetic conductivity forms, and magnetic powder 14 is filled in rotor 15
Between pole shoe 20, it is connected with cooling water 21 in pole shoe 20, fan blade is equipped on rotor and carries out air cooling, armature spindle 11 uses key
It is connected with 6 axis of reel for yarn and rotates with 6 axis of reel for yarn or be connected by gear 7, belt with 6 axis of reel for yarn.
When coil 17 has direct current to pass through, 17 surrounding of coil generates the magnetic line of force 22, work of the magnetic powder 14 by the magnetic line of force 22
With and magnetize, so that magnetic powder 14 is formed magnetic linkage under the action of the magnetic line of force 22, and form attachment force between rotor 15 and pole shoe 20.
At this point, since pole shoe 20 is motionless, so that reel for yarn 6 be made to brake.As long as adjusting the size of excitation current, i.e., changeable braking moment
Size, braking moment is substantially proportional to excitation current.
The utility model is exemplarily described above, it is clear that the utility model implements not by aforesaid way
Limitation, as long as not using the method concept of the utility model and the improvement of various unsubstantialities that technical solution carries out, or not
It is improved that the conception and technical scheme of the utility model are directly applied into other occasions, in the protection model of the utility model
Within enclosing.The protection scope of the utility model should be determined by the scope of protection defined in the claims.
