Description

Technical Field

[0001] The utility model belongs to the technical field of roll grinding, and more specifically, it relates to a device for on-line roll profile grinding. Background Art

[0002] The roll pressing process is an important link in the lithium-ion battery sheet making process. Generally, it is arranged after the coating process and before the cutting process. The roll pressing process enables the electrode sheet to obtain an appropriate compaction density, allowing the active material particles to be in close contact to form a good conduction path. After the roll has been in the roll pressing process for a period of time, the working area of the roll is severely worn, resulting in a poor roll profile. During rolling, wrinkles will appear at the edges of the battery electrode sheet, thus greatly affecting the performance of the electrode sheet. Therefore, the roll needs to be ground.

[0003] There are two existing methods for grinding rolls. One is to disassemble and grind the roll and then reinstall it for use. This method not only causes a long downtime and high maintenance costs, greatly affecting production efficiency, but also, with the development of the rolls of rolling mills towards large-scale, due to the lack of large lifting equipment, it is difficult to disassemble and assemble the rolls; the other is to perform on-line grinding through a grinding wheel or abrasive belt. However, during the grinding process, the feed rate needs to be continuously adjusted. Otherwise, there will be a violent collision and tool breakage during the grinding moment, and even the corresponding components will be thrown flying, resulting in a more troublesome dressing and low dressing efficiency.
