Fig. 2 is the internal structure schematic diagram of the present invention.
Specific implementation mode
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, however, it is desirable to explanation
It is that the explanation to following implementation is schematical, does not constitute the specific restriction to the present invention.
Referring to Figures 1 and 2, a kind of coiled strip swelling unwinding device, including rotating mechanism 1 and the rotating disc component that is attached thereto
2, the rotating disc component 2 includes turntable main body 21, and circumferentially activity distribution has at least two expanding blocks 22 in turntable main body 21；
Movable block 3 is abutted against with the expanding block 22 by wedge structure, be connected on expanding block 22 driving its radially-inwardly tighten in
Elastic component 9 on movable block 3, in the present embodiment, the inside of the expanding block 22 have arcuate furrow, all expanding blocks 22
Arcuate furrow forms a circle the mounting groove of circular ring shape, the elastic component 9 be placed in it is in the mounting groove and end to end
Tension spring；Straight line driving mechanism 4 is connect with movable block 3, for drive movable block 3 along the axial movement of turntable main body 21 so that
Expanding block 22 radially outward either moves inward with respect to turntable main body 21 and then swelling or unclamps coiled strip.Apparatus above passes through
Straight line driving mechanism 4 pushes movable block 3 to move along a straight line, and then can be driven through the swelling that wedge structure is abutted with movable block 3
Block 22 is moved radially outward, and on rotating disc component 2, and rotate coiled strip swelling under the action of rotating mechanism 1, is pacified
The high degree of automation of assembly and disassembly coiled strip, and higher concentricity between coiled strip and rotating disc component 2 is maintained, reduce gold
Tensioning fluctuation of the categoryization film when unreeling, the ultimate guarantee stability of the quality of capacitance core paper, to be conducive to capacitance
Quality.Herein, rotating mechanism 1 is servo motor or stepper motor.
In the present embodiment, the rotating mechanism 1 is connect by rotation axis 5 with turntable main body 21, in the inside of rotation axis 5
The inside of sky, rotation axis 5 is provided through an axis of traction 6 being connected with movable block 3, and the other end of the axis of traction 6 is fixed with one
The quill 7 being sleeved on outside rotation axis 5 is provided with the second elastic component 8, the straight line between quill 7 and rotation axis 5
Driving mechanism 4 is swollen to drive movable block 3 and expanding block 22 to coordinate for driving the quill 7 to relatively rotate the axial movement of axis 5
Tight or release coiled strip.Wherein, the axis of traction 6 is connect by fixed pin 10 with quill 7, is opened up in rotation axis 5 useful
In avoiding the avoiding space 51 that passes through of the fixed pin 10, and fixed pin 10 can be in the avoiding space 51 along rotation axis 5
It moves axially back and forth, when rotating mechanism 1 drives rotation axis 5 to rotate, rotation axis 5 can drive axis of traction 6 by fixed pin 10
It is rotated together with quill 7, to realize the function of unreeling.
When the coiled strip swelling unwinding device work of above structure, quill 7 drives under the action of the second elastic component 8 and leads
Draw axis 6 towards medial movement, so that movable block 3 is radially outward ejected expanding block 22 by the cooperation of wedge structure, from
And swelling coiled strip, when needing to unload coiled strip or when being put into new coiled strip, straight line driving mechanism 4 pushes forward quill 7,
Quill 7 drives the Forward of axis of traction 6 so that movable block 3 is displaced outwardly, and expanding block 22 is inwardly tightened to be resisted against movable block 3
Lozenges on, at this moment, in turntable main body 21 activity installation expanding block 22 and coiled strip between have gap, to unload coiled strip
Or it is put into new coiled strip.
The invention also includes the housing unit 11 for being fixedly mounted in rack, which is set in rotation axis
5 and quill 7 outside, straight line driving mechanism 4 includes being rotatably arranged on swing span 41 on housing unit 11, the swing span
