The invention relates to a spray head tilting mechanism, which comprises a fixed cantilever, a rotary driving motor fixedly arranged on the fixed cantilever, a rotating frame arranged at the rotary driving motor, a parallel rod hinge mechanism arranged at the rotating frame and fixedly provided with a spray head and a linear motor driving the parallel rod hinge mechanism,. The parallel rod hinge mechanism includes at least two spindles arranged in parallel and having the same movement track, at least two connection rods arranged in parallel and having the same movement track, and a plurality of fixed pins connecting the spindles and the connection rods and enabling the spindles and the connection rods to be arranged in interval. One ends of the connection rods suspend and are fixedly provided with sprayer heads. The rotating frame and the parallel rod hinge mechanism rotate around the driving motor under the rotation of the rotary driving motor, the parallel rod hinge mechanism moves through being driven by the linear motor and can make the spray head rotate around a preset forming point, the fixation of the forming point position is ensured, and higher forming efficiency and forming precision are realized.
