Quantitative feeding device of stirring equipment

The invention discloses a quantitative feeding device of stirring equipment. The quantitative feeding device comprises a stirring tank, a movable block, a rotating plate, an elastic clamping plate and a switching assembly used for intermittently driving a proportioning bottle to rotate and switch positions, the contact assembly is used for enabling the rotating plate to be in contact with the switching assembly so as to realize clearance fit and further ensure the moving switching of the rotating plate; when a motor slowly drives a first movable plate to do circular motion and an abutting column enters a notch of a limiting ring, on one hand, a sliding plate is acted to enable an abutting piece to abut against the proportioning bottle to complete addition of an additive, and on the other hand, an arc-shaped plate is acted to enable a sliding block to move, so that a rotating plate is in contact with a self-rotating plate, and the matching bottle is clamped; and after the additive is dripped, the clamping groo
