Spraying device of gluing machine

The utility model relates to the technical field of mask plate gumming machine equipment, in particular to a gumming machine spraying device, which comprises a nozzle, a movable seat capable of reciprocating along the length direction of the nozzle is sleeved on the outer wall of the nozzle, two sides of the movable seat are movably connected with support plates through clamping components, and laser sensors are arranged at the lower ends of the support plates. According to the utility model, the two laser sensors are additionally arranged at the end part of the nozzle, so that on one hand, the levelness between the nozzle and the substrate can be measured in real time to avoid spraying when the substrate is placed unstably, and on the other hand, the coating gap can be calculated in a manner of measuring the distance between the nozzle and the substrate; and when the calculated coating gap is the same as the interval of the set program, the nozzle can normally spray, double insurance is achieved, and the spr
