[0024] During operation, a raw material stirring device for aircraft tire production in the above-mentioned technology will inevitably have a small amount of raw materials attached to the inner wall of the internal stirring mechanism, scraper and stirring drum after a long period of operation, and the interior needs to be cleaned regularly. However, since the stirring drum is connected to the outside world only through the feed port on one side, it is inconvenient to clean it.
