It is rotated relative to mandrel 21.
Three fixed rolls 1 are arranged above and below into one group, and two floating rollers 2 are arranged above and below into one group.Two floating rollers 2 and three fixed rolls 1
Lateral separation.Winding article 50 is sent into from the fixed roll 1 of the top, first around the floating roller 2 that is located above, further around excessively intermediate fixed roll 1,
Underlying floating roller 2 is then passed around, is finally sent out from the fixed roll of bottom 1.The tape transport direction of winding article 50 is T.
Mounting base 3 is can be installed in straight-line displacement on guide rail 4.In winding process, driving unit 5 connects by flexibility
Fitting 6 applies a pulling force to floating roller 2 and keeps, this pulling force offsets with the tape transport tension F1 resultant force F3 acted in floating roller 2,
It can control the tape transport tension F1 of winding article 50, tape transport tension F1=resultant force F3/4.
Tension sensor 7 is installed in the junction of flexible connecting member 6 Yu mounting base 3, can provide the measurement of pulling force in real time
Value.Between the measured value for this pulling force that driving unit 5 is fed back according to tension sensor 7 and the slippage power (i.e. pulling force) of setting
Relationship can obtain more accurate tape transport tension F1 to adjust the slippage power of setting.
Driving unit 5 includes rotatable force piece 51, shaft coupling 52, power twister 53 and wheel 54.Wherein, rotatable
Force piece 51 by shaft coupling 52 to power twister 53 provide rotary power.Power twister 53 is used for according to rotatable force piece 51
Rotation (direction of rotation Z, contrary with resultant force F3) and provide setting slippage power.Wheel 54 is driving unit 5
Output end.In the case of the setting speed and torque output of rotatable force piece 51, the input current of power twister 53 is adjusted
Or input voltage, the size of this adjustable slippage power；In other words, the size of slippage power passes through the input current of power twister 53
Or input voltage is adjusted.For example, rotatable force piece 51 is motor or rotary cylinder.Power twister 53 is hysteresis

The output end of power twister 53 is connected.One end of flexible connecting member 6 is connected with wheel 54, the other end is via tension sensor 7 and peace
Seat 3 is filled to be connected.In the present embodiment, flexible connecting member 6 selects flexible wires.In other embodiments, flexible connecting member 6 can select
With flexible-belt or flexible net.
In this way, which the rotation of rotatable force piece 51 matches, energy via the transmission of shaft coupling 52 with power twister 53
The enough slippage power for applying setting on wheel 54.In other words, by means of the cooperation of rotatable force piece and power twister 53, driving
Unit 5 can provide stable pulling force to the flexible connecting member 6 being connected on wheel 54, offset with resultant force F3.
It is understood that in certain embodiments, shaft coupling 52 above-mentioned can save, rotatable force piece 51 is straight
It connects and connect cooperation with the input terminal of power twister 53.
Compared with prior art, the tenslator 10 of lithium battery winding apparatus of the invention, passes through fixed roll 1, floating roller
2, the ingenious cooperation of mounting base 3, guide rail 4, driving unit 5, flexible connecting member 6 and tension sensor 7, with rotatable power
Part 51, power twister 53 and wheel 54 constitute driving unit 5, apply by the flexible connecting member 6 being connected with wheel 54 smoothly
Floating roller 2 of the pulling force to mounting base 3 and thereon；Also, by the pull sensing being installed between flexible connecting member 6 and mounting base 3
Device 7 to capture the measured value of pulling force in real time, and the slippage power for the setting that driving unit 5 provides is adjusted with this measured value, with
Realize the control to tape transport tension F1, control precision is high and easy to control.
Referring to fig. 4 and Fig. 5, Fig. 4 be lithium battery winding apparatus of the invention another embodiment of tenslator knot
Structure signal.Fig. 5 is the structural representation of floating roller in embodiment illustrated in fig. 4, mounting base, guide rail and tension sensor.The present invention proposes
A kind of tenslator 10c of lithium battery winding apparatus, the difference with tenslator 10 above-mentioned are mainly reflected in:
Mounting base 3c is only installed with a floating roller 2, and corresponding with floating roller 2 is two fixed rolls 1 being arranged above and below, tape transport tension to the left
F1=resultant force F3/2.
In other embodiments, the number of the number of floating roller 2 and fixed roll 1 can have more the needs of practical application and become
Change.The number of floating roller 2 changes, and the relationship between tape transport tension F1 and resultant force F3 corresponding can also change, such as: floating roller
When 2 number is three, tape transport tension F1=resultant force F3/6, when the number of floating roller 2 is four, tape transport tension F1=resultant force F3/8.It can
With understanding, within the scope of the driving capability of driving unit 5, increase the control that 2 number of floating roller is conducive to improve tape transport tension F1
Precision processed.
Above content is only presently preferred embodiments of the present invention, is not intended to limit embodiment of the present invention, and this field is general
