Polar plate rolls cuts device and grid structure who corresponds thereof

The utility model belongs to the technical field of battery production technology and specifically relates to that relate to is a polar plate rolls cuts device and grid structure who corresponds thereof. The utility model discloses a breach cutter that has the breach rolls cuts grid structure, can roll the polar plate that two shapes of eager play sizes is unanimous simultaneously, and during theoperation of breach cutter, the condition of the flagging deformation of polar plate utmost point ear can effectively be solved for discontinuity, far be less than among the prior art power of the long period that the circular knife cutter applyed grid structure to the power applyed grid structure. Simultaneously, the utmost point ear of the two poles of the earth board sets up relatively, has actd as grid structure's complementary unit, plays the enhancement and to the holding power of relative polar plate utmost point ear, can further prevent the flagging deformation of utmost point ear of polar plate, reduces and r
