[0002] Printing ink is a uniform mixture of colored body (such as pigment, dye, etc.), connecting material, filler, additional material and other substances, which is a paste-like adhesive body with color and certain fluidity. As a raw material for printing, the mixing quality of printing ink is one of the key factors determining the printing quality. Therefore, the printing ink is usually mixed by using a fast stirring device at present, and the shear force during stirring is increased by increasing the rotating speed to make the printing ink more uniform.

[0003] During the high-efficiency printing ink mixing process of the printing ink fast stirring device, as the rotating speed increases, the resistance encountered by the stirring blade also increases, and the resistance is finally transmitted to the driving shaft. In particular, the connection area between the stirring blade and the driving shaft constitutes a highly stressed part, and the increase of resistance easily leads to damage to this critical part. In addition, according to the prior art, the connection between the stirring blade and the driving shaft mainly depends on traditional means such as key connection, threaded connection or welding connection. However, these connection methods gradually show their shortcomings when facing high-speed stirring requirements, and it is difficult to ensure long-term stable operation, thereby shortening the service life of the entire device and increasing the maintenance cost.
