The embodiment of the invention discloses an angle control device of a knife-type nozzle, comprising two lifters respectively arranged at both sides of the angle control device, two connecting rods respectively connected with the two lifters, two knife-type nozzles respectively connected with the two connecting rods, and two connected beams on which the two knife-type nozzles are hung, wherein thetwo lifters are respectively connected with two servo motors; when the angle of the nozzle is regulated, the servo motors control the motion of the lifters according to received pulse signals to drive the connecting rods to move, thereby enabling the knife-type nozzle to make the corresponding rotation, forming a certain jetting angle to carry out both-side jetting on a zinc galvanized steel plate, thereby accurately and stably controlling the jetting angle of the knife-type nozzle.
