BLADE DRIVING APPARATUS AND CUTTING DEVICE

This application relates to the technical field of lithium battery manufacturing, and specifically, to a blade driving apparatus and a cutting device. The blade driving apparatus is configured to drive a blade in the cutting device to cut a web and includes: an anvil; and a slide assembly, including a slide rail and a slide block that are slidably connected to each other, where the slide block is connected to the anvil, and the slide block and the anvil move back and forth against the slide rail along a travel direction of the web, and at least one of the slide rail or the slide block is made of a non-metallic material. With the slide rail or slide block made of a non-metallic material, the driving apparatus formed in the foregoing connection manner incurs lesser wear of metal materials during operation, and in turn, generates no metallic particulate matters, thereby alleviating the problem that the drop of metallic particulate matters results in battery safety hazards during cut driving.
