As Fig. 1～shown in Figure 3, the utility model is by binding bolt 1, end cap 2, torsion spring 3, elastic positioning pin 4, steady ring 5, straight pin 6, housing 7, flange mandrel 8, push pedal 9, packing ring 10, sliding panel 11, bulge loop 12, bolt hole 13, axially push pedal guide groove 14, projection 15, locating notch 16, cavity 17 compositions such as grade.
As Fig. 1～shown in Figure 3, the utility model is a kind of band push pedal automatic rotary paper-loosing collet, and it comprises flange mandrel 8, and flange mandrel 8 is made up of flange and mandrel.Be provided with bulge loop 12 near the mandrel place on the flange, form annular groove between bulge loop 12 and the mandrel, the outer circumference of flange has bolt hole 13, and flange mandrel 8 is connected on the S. A. of external propulsion source by bolt hole 13.
Have axial notch on the outside face of the mandrel of flange mandrel 8, axial notch is preferably six, and its cross-sectional plane is gradually opened circular arc for symmetry.The outer housings 7 that are set with of flange mandrel 8, housing 7 activities are engaged in the annular groove between the mandrel of bulge loop 12 and flange mandrel 8, packing ring 10 are installed, in order to alleviate the wearing and tearing between flange and the housing 7 in the annular groove.Have the pilot hole that endwisely slips on the housing 7, the slide-and-guide hole is uniform on circumference, is three in the present embodiment.Endwisely slipping of housing 7 has axial push pedal guide groove 14 between the pilot hole, axially push pedal guide groove 14 also is three.Be set with push pedal 9 outside the housing 7, be provided with projection 15 in the centre hole of push pedal 9, projection 15 is slidingly fitted in the axial push pedal guide groove 14.The bottom surface of push pedal 9 is provided with the concave station rank, and the bulge loop 12 of flange mandrel 8 matches with the concave station rank.
In the slide-and-guide hole of housing 7 sliding panel 11 is installed, the quantity of sliding panel 11 is consistent with the quantity in slide-and-guide hole, also is three.The outside face of sliding panel 11 is the face of cylinder, and its inside face is for gradually opening the inner arc combinatorial surface.The two ends of sliding panel 11 are provided with the circular arc small boss, and the effect of small boss is to prevent that sliding panel 11 from coming off in the slide-and-guide hole of housing 7.
Between sliding panel 11 and the flange mandrel 8 straight pin 6 is installed, straight pin 6 has six, installs one in each axial notch of flange mandrel 8, and the two ends of straight pin 6 are provided with steady ring 5, and 5 pairs of straight pins 6 of steady ring play the axial location effect.
The axle head of flange mandrel 8 is connected with end cap 2 by binding bolt 1, and binding bolt 1 is connected in the center tapped blind hole of flange mandrel 8.The outer end of end cap 2 is taper, play the guiding role, and can easily the utility model be penetrated the hollow shaft of coil paper.Locate by elastic positioning pin 4 between end cap 2 and the flange mandrel 8.
The bottom of the top of flange mandrel 8 and end cap 2 is provided with corresponding cavity 17, is equipped with torsion spring 3 in the cavity 17.Torsion spring 3 has two, is enclosed within outside the binding bolt 1, and the rotation direction of two torsion springs 3 is opposite.In the axle head locating notch groove of an embedding flange mandrel 8 of the torsion spring 3 in the flange mandrel 8, the other end embeds in the locating notch groove 16 of housing 7, in like manner overlapping face-to-face with the torsion spring of having adorned 3 another torsion spring 3, in the locating notch groove 16 of an embedding housing 7 of torsion spring 3, the other end embeds in the locating notch groove of conical head 2 end counterbore.
Principle of work of the present utility model and working process are as follows:
When 8 rotations of flange mandrel; some uniform straight pins 6 roll along the arc surface of gradually opening that is provided with on flange mandrel 8 outside faces; push sliding panel 11 simultaneously open to radially direction expansion; it is the endoporus of swelling body paper mandrel; when swelling moment during greater than body paper mandrel rotating torque; tension force just can not increase again, has therefore protected the endoporus of body paper mandrel.Sliding panel 11 arc surfaces and body paper mandrel endoporus area of contact are big in addition, and pressure reduces, and the endoporus of not fragile body paper mandrel has prolonged its service life.
After flange mandrel 8 is fixing with the S. A. of bolt and external propulsion source, when rotating, the S. A. of external propulsion source drives 8 rotations of flange mandrel, 6 arc surfaces of gradually opening along flange mandrel 8 of straight pin roll, and push sliding panel 11 open, the external diameter of sliding panel 11 is increased and swelling body paper mandrel endoporus, drive the body paper mandrel and rotate together, carry out coil paper or put the paper operation.When 8 rotations of flange mandrel, drive torsion spring 3 pretensions, when flange mandrel 8 did not rotate, the predetermincd tension of torsion spring 3 discharged, and housing 7 backward rotation (in the 30 degree radians) are stirred in the other end of torsion spring 3, and then sliding panel 11 is thrown off automatically with body paper mandrel endoporus.If 8 opposite spins of flange mandrel, then straight pin 6 along flange mandrel 8 gradually open the arc surface backscrolling, in like manner push sliding panel 11 open, the external diameter of sliding panel 11 is increased and swelling body paper mandrel endoporus gradually, drive body paper mandrel backward rotation together.When flange mandrel 8 backward rotation, drive another torsion spring 3 reverse pretensions, when not rotating, the predetermincd tension of another torsion spring 3 discharges, and stirs housing 7 for one of another torsion spring 3 and reverses, and makes sliding panel 11 unclamp body paper mandrel endoporus.
The utlity model has following advantage:
1, when the body paper mandrel, old body paper mandrel particularly is when taking off not open with the paper gripping head paperboard, start user's cylinder, by cylinder push-rod withstand push pedal 9 vertically push pedal gathering sill 14 move axially, the body paper mandrel that blocks is pushed away paper gripping head, automatically get rid of paper jam error, time saving and energy saving.
2, when automatic dilation paper chuck rotates, tension force increases, and drives simultaneously the torsion spring pretension, produces the pretightning force that resets, up and down two torsion springs respectively about the pretension housing to the pretightning force that resets. When automatic dilation paper chuck did not drive the rotation of body paper mandrel, the release of pretightning force because torsion spring resets made housing counter-rotating 30 degree with interior radian, and sliding panel and body paper mandrel endoporus are thrown off.
3, the circular arc of gradually opening of the symmetry of flange mandrel axial notch matches with the inner surface of gradually opening the inner arc combinatorial surface of sliding panel, the tension force that produces is adjusted automatically with the turning moment size, turning moment is big, the tension force of chuck is just big, turning moment is little, the tension force that chuck can need is also little, does not have tension force without turning moment.
4, the conical design of end cap end makes the utility model easy for installation, decides easily the reel center, stability of rotation, and reel two ends are avoided axial clamping force, and the axle head that has reduced reel damages.
5, sliding panel swelling refill axle endoporus, contact-making surface is big, and pressure reduces, and adds tension force and can automatically regulate with turning moment, has effectively protected refill axle endoporus, has prolonged the service life of ten hundreds of refill axles, has reduced the production cost of paper product.
