The invention discloses a gelatinizing head of gelatinizing equipment, and relates to a gelatinizing head with rotary gelatinizing nozzles for one-component glue. The gelatinizing head comprises a gelatinizing nozzle rotating mechanism, a gelatinizing nozzle opening and closing mechanism, a glue supply metering device and a glue supply conveying device which are fixed on a frame composed of a fixed plate, an insulation board B, an insulation board A, a fixed seat and a support plate; the gelatinizing nozzle rotating mechanism comprises a motor A, a speed reducer A, a gelatinizing nozzle A, a gelatinizing nozzle B, a transition body, a guide holder and a seal ring A, the motor A, the speed reducer A and the gelatinizing nozzle B are fixedly connected in sequence, the gelatinizing nozzle A and the gelatinizing nozzle B are combined through a trapezoidal slideway or a dovetail slideway, the gelatinizing nozzle A can move along the gelatinizing nozzle B in the axial direction, a movable plate is fixedly connected with a boss on the upper portion of the gelatinizing nozzle A, and the motor A and the speed reducer A rotatably drive the gelatinizing nozzles to rotate intermittently or continuously. Gelatinizing nozzle rotating is achieved, complex gelatinizing equipment is not needed, three-axis gantry gelatinizing equipment can also complete gelatinizing of workpieces, and the application range of the gelatinizing equipment is widened.
