Technical Field

[0001] The utility model relates to the field of micro-concave rollers, in particular to a micro-concave roller driving and locking device. Background Art

[0002] Micro gravure coating is a type of gravure coating and belongs to roller coating. Micro gravure coating uses a gravure roller with a smaller diameter and reverses the gravure roller. It does not use the traditional pressed back roller coating method, but uses two closely spaced matching rollers with the same (or close) rotation speed to fully flatten the substrate in the opposite direction of the gravure roller's rotation line speed and make slight contact with the gravure roller.

[0003] However, since the micro-concave roller needs to be replaced during use, the locking mechanism of the micro-concave roller provided in the conventional micro-concave roller uses a pressing block to press on the top of the bearing, which makes replacement and disassembly more troublesome.
