Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
With reference to Fig. 1 and 2, present embodiment provides a kind of adjustable spool of torsion, and the adjustable spool of this torsion includes rotating
Body 1, mandrel 2 and torsion adjusting means, rotor 1 is rotating to be enclosed within mandrel 2, and the outer wall of rotor 1 is provided with for even
The connecting portion of splicing band inner ring end, torsion adjusting means is positioned at the side of rotor 1, including being set on mandrel 2 and can
The regulating block 4 moved axially along mandrel 2, regulating block 4 is internally provided with the spring 5 being set on mandrel 2, and spring 5 one end supports
On the regulating block 4 inwall away from one end of rotor 1, spring 5 other end supports on the block 6 arranged on mandrel 2, regulation
Block 4 is provided with stop nut 7, stop nut 7 and the threaded engagement on mandrel 2 away from the outside of one end of rotor 1.
The adjustable spool of this torsion, stop nut 7 is in rotary moving to rotor 1 direction, and spring 5 is under pressure, regulating block 4
Near rotor 1, after the end of regulating block 4 contacts with the end of rotor 1, produce with regulating block 4 when rotor 1 rotates
Kinetic force of friction, further regulation stop nut 7, if the pressure between regulating block 4 and rotor 1 increases, kinetic force of friction increases,
The material strip being enclosed within spool needs bigger external force to be transmitted, if the pressure between regulating block 4 and rotor 1 reduces, dynamic
Frictional force reduces, and the material strip being enclosed within spool needs less external force to be transmitted, and then have adjusted torsion.Due to regulating block 4
And there is kinetic force of friction between rotor 1, when, after complete one section of web feed, rotor 1 will not continue to rotate, and material strip will not occur
Relax, and the torsion tunable arrangement of this spool is positioned at rotor 1 side, compact conformation, saves space.
Concrete, as in figure 2 it is shown, rotor 1 is removably connected with the first friction plate 8 near one end of regulating block 4, it is simple to
Change the first friction plate 8 so that spool extends service life, and on regulating block 4, the one end near rotor 1 is provided with the second friction
Sheet 10.Being arranged with torsion spring 9 on regulating block 4 medial wall, torsion spring 9 is set on the second friction plate 10, is used for connecting regulating block 4 and
Two friction plates 10, torsion spring 9 can be fixed the second friction plate 10, prevent the second friction plate 10 from rotating with the first friction plate 8 simultaneously.Root
Understanding according to said structure, the second friction plate 10 is equally changed.Mutually produce between first friction plate 8 and the second friction plate 10
Kinetic force of friction, easily causes abrasion, owing to the two friction plate is replaceable, can carry out regular update, and otherwise friction plate damages
After can affect service life of overall spool.
The connecting portion of present embodiment is spring leaf 3, is connected one end of material strip inner ring by spring leaf 3, it is possible to be applicable to
The situation that material strip internal diameter is bigger, anti-stopping materials strip skids off.
The adjustable spool of torsion of present embodiment also includes fixing seat 11, as it is shown in figure 1, the adjusting away from torsion of mandrel 2
One end of regulating device is fixed on fixing seat 11.
When being transmitted material strip by the adjustable spool of the torsion in present embodiment, first fixing seat 11 is arranged on solid
Location is put, and is enclosed within by material strip on rotor 1, and spring leaf 3 blocks one end of material strip inner ring, and anti-stopping materials strip skids off；Pull material strip,
By regulation stop nut 7 compression spring 5, regulated the torsion of spool by the size of increase and decrease kinetic force of friction, it is achieved to spool
Fine setting, it is possible to be applicable to the material strip of different performance.
Note, above are only preferred embodiment of the present utility model.It will be appreciated by those skilled in the art that this utility model is not
It is limited to specific embodiment described here, various obvious change can be carried out for a person skilled in the art, readjust
With replacement without departing from protection domain of the present utility model.Therefore, although by above example, this utility model is carried out
It is described in further detail, but this utility model is not limited only to above example, conceive without departing from this utility model
In the case of, it is also possible to include other Equivalent embodiments more, and scope of the present utility model is determined by scope of the appended claims
Fixed.
