The height H of the roll extrusion portion described in the present invention is 1～3mm, and preferable width is 1～2mm.The rolling width W of the height H of roll extrusion portion and battery pole piece is suitable.
Transmission mechanism described in the present invention comprises belt pulley, travelling gear, the power transmission shaft that links to each other successively, and described motor links to each other with belt pulley, and described power transmission shaft links to each other with roller, and wherein power transmission shaft also is a pair of, is installed on the power transmission shaft support.
The material of described roller is a hard alloy steel.
Compared with prior art, the present invention has following remarkable result:
1) the present invention can effectively eliminate the burr of battery pole piece shearing place, thereby solved the difficult problem that punctures barrier film that battery pole piece usually occurs in the prior art in winding process, avoid battery short circuit, improved the qualification rate of battery greatly, also reduced production cost simultaneously;
2) the deburring edge knurling machine among the present invention adopts the roller of variable cross-section, only partial operation is carried out in battery pole piece shearing place, obviously reduces the destruction to the battery pole piece surface body, has improved the effect of deburring;
3) in the battery pole piece burr removing method of the present invention, can satisfy the production requirement of battery pole piece serialization, and can significantly improve the performance of battery pole piece.
