When in use, the handle 4 is pulled to separate the clamping ring 3 from the dispersing tank 1, so as to facilitate the disassembly of the cover plate 2 and the dispersing unit 6, so as to facilitate the staff to pour the powder of the ultrafine conductive slurry into the dispersing tank 1.

[0024] The dispersion unit 6 includes a rotating shaft 601, which is rotatably connected to the lower side of the cover plate 2, a stirring plate 602 is fixedly connected to the outer side of the rotating shaft 601, a fixing ring 603 is fixedly connected to the outer side of the upper end of the rotating shaft 601, a plurality of connecting rods 605 are fixedly connected to the outer side of the fixing ring 603, a knocking ball 606 is fixedly connected to the outer side of the connecting rod 605, a fixing plate 607 is fixedly connected to the lower side of the cover plate 2, two fixing blocks 608 are fixedly connected to the outer side of the fixing plate 607, a rotating plate 609 is rotatably connected between the two fixing blocks 608, a spring 610 is rotatably connected between the rotating plate 609 and the fixed plate 607, metal blocks 611 are fixedly connected to the front and rear sides of the rotating plate 609, the spring 610 is arranged in an inclined structure, the knocking ball 606 is made of metal material, and when in use, the rotating shaft 601 is controlled to rotate , so that the stirring plate 602 rotates, and at the same time, the rotating shaft 601 drives the fixed ring 603 to rotate, the fixed ring 603 drives the connecting rod 605 to rotate, the connecting rod 605 drives the knocking ball 606 to rotate, the knocking ball 606 drives the rotating plate 609 to rotate, and the rotating plate 609 drives the spring 610 to compress. When the knocking ball 606 passes over the rotating plate 609, the rotating plate 609 is reset under the action of the elastic force of the spring 610, so that the next knocking ball 606 knocks the metal block 611 on the rotating plate 609, so that the fixed ring 603 generates vibration and transmits it to the rotating shaft 601 and the stirring plate 602, so that when the stirring plate 602 disperses the powder, the powder dispersion effect is increased by vibration. When the dispersion is completed, the rotating shaft 601 is continuously controlled to rotate, so that the powder adhering to the stirring plate 602 is shaken off to avoid waste of powder.

At the same time, the rotating shaft 601 drives the knocking ball 606 to rotate. Under the action of the rotating plate 609, the spring 610, and the metal block 611, the knocking ball 606 vibrates, which is convenient for the vibration to be transmitted to the stirring plate 602, thereby increasing the dispersion effect. After the dispersion is completed, the adhesion is separated and shaken off through vibration to avoid waste of powder.
