Problems solved by technology

[0004] At present, due to the clearance of the bearing, in the process of rolling the battery pole piece, because the battery pole piece is coated intermittently, the rolling process must be intermittent rolling
During the discontinuous process, the roll jumps within the clearance range of the bearing, causing violent fluctuations in the rolling force, thus affecting the rolling effect

Abstract

The invention relates to battery pole piece rolling equipment reasonable in bearing clearance. The battery pole piece comprises a machine frame set and a roller set arranged on the machine frame set in a hinged mode. The machine frame set comprises an oblique supporting underbed and a vertical supporting underbed connected with the oblique supporting underbed. The roller set comprises a first stand column, a second stand column, a lower battery pole piece roller, an upper battery pole piece roller and two movable connecting racks, wherein the first stand column and the second stand column are symmetrically arranged on the vertical supporting underbed, the lower battery pole piece roller and the upper battery pole piece roller are arranged between the first stand column and the second stand column, and the movable connecting racks are connected with the first stand column and the second stand column correspondingly. The battery pole piece rolling equipment reasonable in bearing clearance is compact in structure, reasonable in design, safe, reliable, low in cost, capable of saving time and labor, and suitable for large-scale popularization, and the quality of machined battery pole pieces is high.

Description

technical field [0001] The invention relates to a battery pole piece rolling equipment with reasonable bearing clearance. Background technique [0002] At present, the battery pole piece rolling equipment requires the parallelism of the two rolls. The purpose of this is to ensure the parallelism of the pole piece rolling. However, due to the existence of rolling force and gravity, the roll will inevitably have a certain bending deformation. Even if the parallelism of the two rolls is adjusted to the best, the pole piece after rolling will be slightly thicker in the middle than the two sides (about 0.001~0.01mm ) phenomenon, which ultimately affects the quality of the battery pole piece. [0003] The existing battery pole piece rolling equipment is basically manufactured by professional equipment manufacturers. After a certain period of service (about half a year), the rolls need to be disassembled for grinding. Due to the structure of the equipment, this work needs to be c...
