The servo motor 7 is started by the controller 3 so that its output shaft drives the rotating shaft 8, crank 9, stirring rod 10 and scraper 11 to perform circular motion. The flow of melamine material is promoted by high-torque periodic stirring, which significantly improves the mixing efficiency and uniformity of the melamine material. The scraper 11 cleans the inner wall residue when rotating with the stirring rod 10, thereby achieving real-time cleaning of the inner wall of the storage tank 5, avoiding pollution and efficiency reduction caused by material residue, and achieving the advantages of high mixing efficiency and easy cleaning.
