Present embodiment is two joint combined rotary automatic dilation paper chucks, but the invention is not restricted to two joint combinations, can also be combined into three joints until more piece on the basis of the second joint folder head, depends on the needs.
Principle of work of the present invention and working process are as follows:
When the flange mandrel rotates; some uniform straight pins roll along the arc surface of gradually opening that is provided with on the flange mandrel outside face; push sliding panel 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 arc surface 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.
The present invention has the following advantages:
1, the present invention has the advantage of a tractor serves several purposes, can make up usefulness, also can separate and use separately. A binodal folder head can be used for the body paper mandrel clamping of two kinds of specifications at least.
2, 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, and the tension force that chuck can need is also little, does not have tension force without turning moment, 30 ° of radians will unclamp with body paper mandrel endoporus with interior if reverse, and are easy to use.
3, the conical design of flange mandrel and end cap end makes the present invention 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.
4, 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.
5, applicability is wide, and a machine dual-purpose has enlarged the dimensions of using the refill axle, has reduced replacing time and expenses of labour when different size refill axle uses.
6, according to user's needs, easily change if remove a joint, installs conical head on big flange mandrel top and has just become single-unit folder head.
