[0037] Working principle of this utility model:

[0038] The workpiece 4 is placed on the conveyor belt 20. In actual use, the weight of the workpiece 4 does not need to be considered in the movement on the conveyor belt 20, that is, the workpiece 4 and the upper end surface of the conveyor belt 20 remain relatively stationary, and the conveyor belt 20 is driven by the roller 22, so that the workpiece 4 located above the conveyor belt 20 moves synchronously;

[0039] While the workpiece 4 is moving, the second driving motor 37 drives the second slider 33 to move in the second slide 32. The movement of the second slider 33 drives the spray rack 35 and the nozzle 36 on the spray rack 35 to reciprocate in the second slide 32. The nozzle 36 is connected to the fluid. The nozzle 36 realizes back and forth uniform spraying of the workpiece 4 under the transmission action of the second driving motor 37.

[0040] The height of the nozzle 36 from the collecting plate 1 can be adjusted by rotating the adjusting screw 243 so that the adjusting screw 243 is threadedly matched with the support frame 21. At the same time, the other end is rotatably connected with the mounting plate 25. Since the mounting plate 25 can be slidably adjusted in the first slide groove 24, the mounting height of the mounting plate 25 can be adjusted by rotating the adjusting screw 243, so that the nozzle 36 is located at the optimal height for spraying;

[0041] The adjusting screw 243 can be adjusted in the waist-shaped groove 241. After being adjusted to a suitable position, the adjusting plates 242 on both sides of the waist-shaped groove 241 can be locked by bolts to achieve tensioning of the conveyor belt 20 to ensure the synchronous rotation of the conveyor belt 20 and the roller 22.
