Slide mass it is provided with between support shaft and outer tube pipe.
Slide mass is bearing.
When spline outwards ejects, cam curved surface keeps contacting with spline all the time.
The cam curved surface corresponding with single spline is monoblock type or stagewise.
The beneficial effects of the utility model are, it is possible to eject spline by camshaft, it is not necessary to the optional equipments such as additional gas sources
Just can realize expanding the purpose of locking paper tube paper web by cam axle, more energy-conservation；And it is simple for structure, durable；
Spline outwards ejects, projection by camshaft drive, more stable, it is possible to making spline outwards eject contour, spline outwards ejects
Good concentricity；This utility model compared with prior art has substantive distinguishing features and progress.
Accompanying drawing explanation
Embodiment of the present utility model and the relevant details of embodiment and operation principle are described below in conjunction with the accompanying drawings.
Fig. 1 is structural representation of the present utility model, and wherein spline outwards ejects.
Fig. 2 is structural representation of the present utility model, and wherein spline is inwardly regained.
Detailed description of the invention
Seeing accompanying drawing, in present embodiment, a kind of interior driving cam main axis of dilatation, includes support shaft 1, camshaft 2, outer tube
Cylinder 3, spline 4, rotation wheel 6 and hinge spanner 7.
The two ends of camshaft 2 are connected with support shaft 1 respectively, and support shaft 1 links with camshaft 2, and support shaft and camshaft will
Synchronous axial system.Can assemble convenient by camshaft and support shaft Integral design, during Integral design, mid portion is camshaft
Part, two end portions is supporting shaft portion.Support shaft 1 will be used for being arranged on frame, support support shaft is carried out revolution and prop up
Hold, support shaft can arrange transmission component (such as gear, synchronizing wheel etc.) and carry out transmission with motor and coordinate, motor-driven support
Axle rotates.
Outer tube pipe 3(main body is tubular structure) it is set in outside camshaft 2, outer tube pipe 3 can relative turn with camshaft 2
Dynamic, the when of use, paper tube, paper tube sleeve are located on outer tube pipe.Slide mass 5, slide mass it is provided with between support shaft and outer tube pipe
5 can use bearing, in order to smooth rotation between outer tube pipe and camshaft, and support shaft 1 will be stretched out from outer tube pipe 3 two ends.
Camshaft 2 is provided with cam curved surface (not shown), and outer tube pipe 3 offers window, window and cam curved surface
Being correspondingly arranged, arrange spline 4 in window, the spline 4 in window presses to correspondence by arranging elastic component (such as spring, not shown)
Cam curved surface on, cam curved surface coordinates with spline, and when outer tube pipe and camshaft relatively rotate, camshaft makes cam curved surface outside
Eject spline.When outer tube pipe relatively rotates with camshaft, the cam curved surface on camshaft will outwards eject spline, it is not necessary to additional
In the case of the optional equipments such as source of the gas, it is possible to realize expanding the paper tube paper web outside locking outer tube pipe.Such as, camshaft is relative to outer tube
When cylinder rotates forward, the cam curved surface on camshaft will outwards eject spline, and when camshaft inverts relative to outer tube pipe, cam curved surface is conceded
Spline is pressed to cam curved surface for elastic component by space, makes spline return (retraction).
When outwards ejecting spline 4, cam curved surface keeps contact with spline all the time, therefore in rolling or when unreeling, and spline general
The position outwards ejected can be constantly in.
On outer tube pipe 3, and at least two group windows are set along the axial direction of outer tube pipe 3.Every group window at least provided with
Two windows, can arrange two or three or four windows.Every group window is on outer tube pipe 3 and along outer tube pipe 3 circumferencial direction
First-class setting up separately puts, and when the most often group arranges three windows, then carries out trisection.Arrange corresponding with each group window on camshaft 2
Spline in several cam curved surfaces, i.e. window, the window cam curved surface corresponding with window forms an expansion cell, is used for
Paper tube paper web outside locking outer tube pipe.In each expansion cell the cam curved surface corresponding with spline (single spline) be monoblock type or
Stagewise.Monoblock type is overall continuous print curved surface；Stagewise can be sheathed some (at least two) cam ring on camshaft,
The cam curved surface of stagewise is formed by these cam rings.(and the cam of spline in window and correspondence is bent to arrange many group windows
Face) can stably lock paper tube paper web, decile arranges and is more uniformly stressed.
The window misalignment of two adjacent groups is arranged.Windows in such as one group etc. point arrange three, then another group adjacent
Window is also that decile arranges three, misplaces 60 degree between two groups.Layout is the compactest, and the locking of paper tube paper web is more firm.
One end of camshaft is connected with rotation wheel 6, and camshaft 2 is coaxially disposed with rotating wheel 6, convex by rotating wheel 6 transmissions
Wheel shaft 2 rotates, and rotates and takes turns 6 hinged hinged spanners 7, hinge spanner 7 wheel 6 driving cam axles are rotated and rotate, and convenient use makes
Used time, by pulling hinge spanner 7 manually, hinge spanner 7 is rotated wheel 6 rotation, rotates wheel 6 and rotates together with camshaft 2,
When camshaft 2 and outer tube pipe 3 relatively rotate, the cam curved surface of camshaft 2 makes spline 4 outwards eject, and locks paper tube paper web.
