Slitter

Abstract

Disclosed herein is a slitter. The slitter according to the exemplary embodiment of the present invention includes an unwinding part from which an insulating film is consecutively taken out; a plurality of transfer rollers that transfer the insulating film supplied from the unwinding part in one direction; a wheel knife that senses an air pocket formed on the insulating film taken out from the unwinding part to form fine holes on the insulating film; a cutter that is disposed between the transfer rollers and cuts, at a predetermined interval, the insulating film transferred in one direction through the transfer roller; and a winding part individually winding the insulating film divided at a predetermined interval by the cutter.

1 . A slitter, comprising:
 an unwinding part from which an insulating film is consecutively taken out;   at least one transfer roller that transfers the insulating film supplied from the unwinding part in one direction;   a wheel knife that senses an air pocket formed on the insulating film taken out from the unwinding part to form fine holes on the insulating film;   a cutter that cuts, at a predetermined interval, the insulating film transferred in one direction through the transfer roller; and   a winding part individually winding the insulating film divided at a predetermined interval by the cutter.   
     
     
         2 . The slitter according to  claim 1 , wherein the transfer roller includes a first transfer roller that transfers the insulating film taken out from the unwinding part and a second transfer roller that transfers the insulating film cut by the cutter. 
     
     
         3 . The slitter according to  claim 2 , further comprising a support roller that is located between the first transfer roller and the second transfer roller to transfer the insulating film while being engaged with the first transfer roller and the second transfer roller. 
     
     
         4 . The slitter according to  claim 3 , wherein the support roller has the cutter disposed on the top thereof, the cutter cutting the insulating film passing through the support roller. 
     
     
         5 . The slitter according to  claim 1 , wherein the wheel knife is mounted in front of the first transfer roller and rotates in the same direction as the taking out direction of the insulating film to form a plurality of fine holes on the insulating film. 
     
     
         6 . The slitter according to  claim 1 , further comprising:
 a sensing unit that senses when the air pocket is present on the insulating film taken out from the unwinding part, a control unit that controls the driving of the wheel knife when the air pocket on the insulating film is sensed, and a driving unit that rotatably drives the wheel knife by a driving signal of the control unit.   
     
     
         7 . The slitter according to  claim 5 , wherein the wheel knife is disposed on a top surface of the insulating film at a predetermined interval and when the air pocket is sensed by the sensing unit, moves to the top surface of the insulating film while being rotatably driven so that the cutter on an outer peripheral surface of the wheel knife contacts the top surface of the insulating film.
