The invention relates to the technical field of cap screwing machines, in particular to a spray cap screwing machine capable of rotating at the high speed. The spray cap screwing machine comprises a conveying belt. A bottle feeding threaded rod is arranged at one side of the conveying belt, and a rotary cap pressing and feeding component is arranged at the other side, opposite to the bottle feeding threaded rod, of the conveying belt. The rotary cap pressing and feeding component is connected with a cap feeding guide rail. A rotary cap screwing component and a bottle discharging rotary disc component are sequentially arranged beside the rotary cap pressing and feeding component in the conveying direction of the conveying belt. By means of the structure of the spray cap screwing machine, after entering rotary disc locating grippers, a cap moves in the circumferential direction in a rotary manner; a long suction pipe below the cap enters an inner and outer guiding track ring located below; the locating grippers are driven by a cam to ascend and descend; and the locating grippers ascend in the first place, the inner and outer guiding track ring can automatically arrange the suction pipe to be erected and locate the suction pipe above a bottle opening of a bottle transferred through a synchronous bottle feeding rotary disc, and the locating grippers descend along with the cam, so that the automatic cap feeding function is achieved.
