A pole plate passing roller structure

Abstract

A pole piece passing roller structure is disclosed, It comprises a first passing roller, a first central shaft and a first fixing assembly, wherein one end of the first passing roller inner wall is provided with a first rolling assembly, the other end of the first passing roller inner wall is provided with a second rolling assembly, the first passing roller is connected with the first central shaft through the first rolling assembly and the second rolling assembly, the second rolling assembly is connected with the first central shaft, and the first fixing assembly is connected with one end ofthe first central shaft. The pole piece passing roller structure realizes that the first bearing is not subjected to axial pressure and ensures that the first bearing is in a zero clearance state, sothat the first passing roller is subjected to less frictional force when rotated, the inertia of the first passing roller is small, avoiding the broken belt or wrinkling caused by excessive moment ofinertia of the pole piece, The axial movement of the first passing roller is reduced, a gap is arranged between the second bearingand the second step of the first central shaft, and the axial pressuregenerated by squeezing the second bearing is avoided, so that the second bearing is only used for supporting the first passing roller, so that the resistance of the first passing roller is smaller, and the quality and the yield of the lithium battery cell production are greatly improved.

Problems solved by technology

[0003] At present, in the lithium battery manufacturing industry, it is necessary to use lithium battery cell winding equipment to complete the lithium battery cell winding link. Lithium battery cell winding equipment usually uses many rollers to carry and transmit pole pieces, and The installation method of the existing roller structure is to squeeze the inner ring of the supporting bearing to reduce the gap, so as to reduce the axial transmission, which causes the supporting bearing to be additionally subjected to axial pressure, causing the friction of the roller to rotate When the force increases and the friction increases, the inertia and inertia of the rollers will also increase, resulting in unstable operation effects and overall tension control, thus affecting the quality and pass rate of the lithium battery cells produced by winding.
