Mixing mechanism, mixing device, and mixing method

A mixing mechanism, comprising a support plate, a stop support, a support platform, and a drive unit;

• wherein the first end of the stop support is mounted on the support platform, the support plate is mounted on a second end of the stop support, and the support plate is arranged above the support platform;
• wherein the drive unit is mounted on the support platform, with an output end of the drive unit in movable engagement with the support plate;
• a contact point exists between the drive unit and the support plate, and the contact point is offset from a center of the support plate;
• the drive unit includes an adjuster that acts on a position of the contact point in a first direction;
• the contact point has at least a first movement position in a first direction;
• and when the support plate is supported by the stop support in a natural state, a height difference exists between a height of the support plate and the first movement position;
• the mixing mechanism further comprises a guide rail, a sliding seat, a first pulley, and a second pulley;
• the guide rail is mounted on a lower surface of the support plate and extends circumferentially around the support plate;
• the sliding seat is mounted on the second end of the joint component;
• the first pulley and the second pulley are mounted on the sliding seat;
• the guide rail is arranged between the first pulley and the second pulley, and is slidably connected to the first pulley and the second pulley respectively;
• and
• a connecting rod is fixedly disposed under the sliding seat;
• the drive unit has a sliding shaft and a joint component;
• a first end of the connecting rod is fixed to the joint component, and a second end of the sliding shaft is movably engaged with the joint component.
