Fig. 1 is please referred to, Fig. 1 is the winder gas expansion shaft rolling-up mechanism in one embodiment of the invention, and winder gas expansion shaft is received
Volume mechanism mainly includes illustrating that including two is somebody's turn to do in main shaft 1, cylinder assembly 2 and at least one position limiting structure 3(Fig. 1
Position limiting structure 3).
Referring to fig. 2 and Fig. 3, which includes the first orifice plate 31, the second orifice plate 32 and annular resilient part 33, this
One orifice plate 31 and 32 spacing of the second orifice plate are adjustably sheathed on the main shaft 1.Generally locating part can be set on the main shaft 1
First orifice plate 31 is fixed, which is then movably arranged on the main shaft 1 so that first orifice plate 31 and this
Spacing between two orifice plates 32 is adjustable.A ring-type is defined between first orifice plate 31 and the periphery of 32 opposite side of the second orifice plate
Limit crack, which is set in the limit crack, and the cylinder assembly 2 and second orifice plate 32 are sequentially connected
For adjusting the spacing between first orifice plate 31 and second orifice plate 32.When the cylinder assembly 2 drives second orifice plate
32 to the direction of first orifice plate 31 when moving, and reduces the gap between first orifice plate 31 and second orifice plate 32, that is, contracts
The periphery of the annular resilient part 33 can be squeezed out the limit crack by the width of the small limit crack.In some embodiments it is possible to
It is movably arranged at first orifice plate 31 and second orifice plate 32 all on the main shaft 1, then the biography of cylinder assembly 2 is all arranged in both sides
Dynamic connection, both sides, which respectively apply contrary driving force, subtracts the gap between first orifice plate 31 and second orifice plate 32
It is few, the periphery of the ring elastic parts 33 can equally be squeezed out to the limit crack.
When winder gas expansion shaft rolling-up mechanism is only provided with the position limiting structure 3, cylinder assembly 2 can be fixed on master
It (is not drawn in figure) on axis 1.One end of the main shaft 1 is equipped with rotary joint 5, connect for the rotation drive shaft 8 with winder,
Prevent tracheae from distorting.
When the setting of winder gas expansion shaft rolling-up mechanism is there are two when the position limiting structure 3, referring to Fig. 1, Fig. 4 and Fig. 5, this first
Orifice plate 31 is fixed on the main shaft 1, which movably sets this on main shaft 1, two position limiting structures 3 should
Second orifice plate 32 is set between first orifice plate 31 of two position limiting structures 3, which is set to two second orifice plates
Between 32, with drive two second orifice plates 32 respectively to two first orifice plates 31 close to or far from.
In real work, external inflation device is inflated by tracheae to cylinder assembly 2, stretches out the gas bar of cylinder assembly 2,
Due to the effect of power be it is mutual, gas bar stretching two second orifice plates 32 can be driven to move in the opposite direction simultaneously, make
Two second orifice plates 32 are respectively facing close with first orifice plate 31 that itself belongs to same position limiting structure 3, make same limit
Gap between first orifice plate 31 and second orifice plate 32 of structure 3 is reduced, that is, the width of the limit crack is reduced, by the ring
The periphery of shape elastic component 33 squeezes out the position limiting clamp and is stitched to the edge higher than first orifice plate 31 and second orifice plate 32, and then holds out against
Reel core, to achieve the effect that stuck fast reel core.When needing discharging, air charging system is deflated, and the gas bar of cylinder assembly 2 is received
It returns, which returns to original position under the convergent force effect of the annular resilient part 33.One position limiting structure 3 of setting makes to receive
It is lighter to roll up mechanism structure, two position limiting structures 3 of setting effectively improve the coupling mechanism force to reel core, in practice can be according to reality
Border situation (such as weight, rolling speed of reel core etc.) selects different schemes.
The invention proposes a kind of winder gas expansion shaft rolling-up mechanisms, lock using the harmomegathus similar with traditional gas expansion shaft
Working principle, but devise completely new Pneumatic core shaft structure, it is no longer necessary to use air bag, the weight of reel core does not press against gas when locking
Rise in the other structures of axis, but is pressed on circle elastic component outstanding, and elastic component is cheap, replaces when generating loss
It is convenient, it is more in line with economic principles of production.The ring elastic parts 33 and the first orifice plate 31 and the second orifice plate 32 connect without fixed
Directly the ring elastic parts 33 are removed when connecing, be only stuck in the limit crack, therefore replacing, then change new annular elastomeric
Property part.
Preferably, referring to Fig. 3, first orifice plate 31 of each position limiting structure 3 and the week of 32 opposite side of the second orifice plate
Edge is equipped with from the centroclinal inclined plane part 34 in periphery, which is stuck in the limit crack and connects with inclined plane part 34
Touching, when gap reduce when inclined plane part 34 can it is more smooth, more uniformly by the annular resilient part 33 from the limit crack squeeze out.
Preferably, referring to Fig. 1 and Fig. 4, winder gas expansion shaft rolling-up mechanism is additionally provided with guide rod 4, which is set to two
Between the position limiting structure 3, the both ends of the guide rod 4 be each passed through second orifice plate 32 and end (using spacer screw) be set to this
On one orifice plate 31.Guide rod 4, which is arranged, can make the activity of second orifice plate 32 more smooth, more acurrate.Preferably, the guide rod 4 is upper
Section between second orifice plate 32 and first orifice plate 31 of the position limiting structure 3 is equipped with reset spring 6.The guide rod 4
It is preferred that being equipped with two for symmetry axis with the axial of the main shaft 1, specifically as shown in Figure 1.
Specifically, the cylinder assembly 2 includes a thin cylinder, slim gas for the scheme that a position-limit mechanism 3 is arranged
Cylinder can be fixed on main shaft 1 and (not draw in figure).For the scheme of two position-limit mechanisms 3 is arranged, which includes
Two thin cylinders, two thin cylinders are symmetrically disposed in two second holes by symmetric points of the center of second orifice plate 32
Between plate 32, as shown in Fig. 1 and Fig. 4.
Preferably, which can be elastic rubber ring, preferably ring spring.For ring spring, elasticity
Greatly, resilience is good, and the width of the limit crack can squeeze out the annular stop spring 33 when reducing, and makes the annular stop spring 33
Diameter become larger, and so that the annular stop spring 33 is protruded from the surface of first orifice plate 31, therefore reel core can be held out against
Inner wall.
In the description of this specification, reference term " embodiment ", " certain embodiments ", " schematically implementation
What the description of mode ", " example ", " specific example " or " some examples " etc. meant to describe in conjunction with the embodiment or example
Particular features, structures, materials, or characteristics are contained at least one embodiment or example of the invention.In this specification
In, schematic expression of the above terms are not necessarily referring to identical embodiment or example.Moreover, the specific spy of description
Sign, structure, material or feature can be combined in any suitable manner in any one or more embodiments or example.
In conclusion although the present invention has been disclosed above in the preferred embodiment, but above preferred embodiment is not to limit
The system present invention, those skilled in the art can make various changes and profit without departing from the spirit and scope of the present invention
Decorations, therefore protection scope of the present invention subjects to the scope of the claims.
