NOVELTY - The utility model relates to graphene heat conducting film production processing field, especially relates to a feeding groove for scraping knife coating production graphene comprising a feeding groove body, a multi-stage shunt feeding pipe and a flattening rotating roller group; the inner part of the feeding groove body is provided with a pressure stabilizing material cavity; the bottom of the pressure stabilizing material cavity is connected with the multi-stage shunt feeding pipe; the side wall of the pressure stabilizing material cavity is provided with a slit discharging opening; more than two groups of said flattening rotary roller set in the pressure stabilizing material cavity from close to the multi-stage shunt feeding pipe is interval to the slit discharge port is set. The utility model improves the comma scraper feeding mode, designing a groove with a height adapted, selecting and relieving the graphene film coating mode, improving the feeding uniformity.
