Detailed Description
The technical solution of the present invention will be described in detail with reference to the drawings.
Referring to fig. 1 and 2, the unwinding mechanism of the slitter-winder of the present embodiment includes an unwinding frame 1, an inflatable reel 2, a surface unwinding roller 3, a driving motor assembly 4 of the surface unwinding roller 3, and a tension isolation assembly 5 disposed between a web descending path of the inflatable reel 2 and the surface unwinding roller 3 for maintaining constant tension of the web unwound from the surface unwinding roller 3, wherein the inflatable reel 2, the surface unwinding roller 3, the driving motor assembly 4, the tension isolation assembly 5, and the driving assembly are connected to the unwinding frame 1.
The utility model discloses an unwinding mechanism operating principle who cuts rewinding machine as follows:
the paper tube 7 is sleeved on the inflatable reel 2, the coiled material 8 is coiled on the paper tube 7, the tail end of the coiled material 8 firstly passes through the tension isolation assembly 5 and is held by the tension isolation assembly 5, when the surface unwinding roller 3 rotates, the coiled material 8 is pulled to be unwound, and as the two ends of the coiled material 8 between the surface unwinding roller 3 and the tension isolation assembly 5 are both stably pulled, the coiled material 8 between the surface unwinding roller 3 and the tension isolation assembly 5 is constant tension, so that the influence of the slippage of the coiled material 8 on the inflatable reel 2 on the tension of the coiled material on the surface unwinding roller 3 is isolated. Finally, the slippage between the coiled material and the surface of the coiled material or between the coiled material and the paper tube can be ignored, and the problem that the coiled material cannot be unreeled under constant tension due to the fact that the friction of the surface unreeling roller 3 is unreeled or the large-amplitude fluctuation generated by the reverse pulling force of the central unreeling is avoided.
Referring further to fig. 2, in a first preferred embodiment of the present invention: the tension isolation assembly 5 comprises a tension roller 51 and a pressing cylinder for driving the tension roller 51 to press the surface unwinding roller 3, and the tension roller 51 and the pressing cylinder are connected to the unwinding frame 1; after the down-pressing cylinder drives the tension roller 51 to be pressed down on the surface unwinding roller 3, the coiled material can be held by the surface unwinding roller 3 and the tension roller 51 and is supplied in a relatively rotating manner, no matter whether the coiled material in front of the tension roller 51 and the surface unwinding roller 3 slips or not, the coiled material can be disregarded because the tension between the surface unwinding roller 3 and the coiled material per se is isolated, the tension of the coiled material discharged by the surface unwinding roller 3 cannot fluctuate greatly, the coiled material 8 can be quantitatively supplied only by a signal fed back by the surface unwinding roller 3 and the tension roller 51 behind, and meanwhile, the pressure between the two rollers can be adjusted to control the holding force.
In fig. 2, when the tension roller 51 is positioned above the surface unwinding roller 3, the tension roller 51 is in a disengaged state and cannot play a role of controlling the tension of the web, and when the tension roller 51 is pressed down to contact the surface of the surface unwinding roller 3, the web is held between the rollers and is unwound while rotating, thereby maintaining smooth unwinding.
As for the material of the tension roller 51, it is preferable that the tension roller 51 is a rubber-covered roller.

when the coiled material 8 is held by the first pressing roller 52 and the second pressing roller 53 and is rapidly supplied to the surface unwinding roller 3, and then the speed is suddenly reduced, the coiled material 8 can continuously rotate due to inertia to cause the coiled material 8 to be reversely wound, if a magnetic powder brake is additionally arranged on the coiled material 8, a quantitative reverse pulling force can be provided for the coiled material 8, the principle of the magnetic powder clutch is that the reverse pulling force is adjusted through the given current, and after the coiled material 8 is connected with the magnetic powder clutch, a reverse pulling force always exists, even if the first pressing roller 52 and the second pressing roller 53 pull the coiled material 8 to rotate at a high speed and suddenly stop, the coiled material cannot fly due to inertia, the technology is called that the center and the surface are jointly unwound, so that the coiled material 8 is specially used for the phenomenon that the coiled material 8 is not wound up due to the previous process or the tension is greatly suddenly changed, the slippage between the coiled material and the coiled, problems of uncoiling and core-releasing of a coiled material core!
For the material of the two pressure rollers, preference is given to: the first pressure roller 52 and the second pressure roller 53 are two rollers coated with rubber on the surfaces.
