[0028] The powder recovery device includes a first air pump 4, a collection box 5, a second air pump 8 and a third air pump 9. The first air pump 4 is respectively connected to the powder spraying room 1 and the collection box 5, the collection box 5 is connected to the powder spraying device 6, the second air pump 8 is respectively connected to the collection box 5 and the powder spraying device 6, the third air pump 9 is respectively connected to the collection box 5 and the dust suction nozzle 7, the powder spraying room 1 includes a collection trough 11, and a discharge port 12 is provided on the side of the collection trough 11, and the discharge port 12 is connected to the first air pump 4 through a pipeline. When the powder spraying operation is carried out, the powder in the aggregate box 5 is sucked into the powder spraying device 6 through the third air pump 9, and then sprayed onto the surface of the workpiece through the spray gun 61. The powder scattered in the powder spraying room 1 falls into the aggregate trough 11, and the powder in the aggregate trough 11 is pumped back into the aggregate box 5 for collection through the first air pump 4. The second air pump 8 is used to generate a negative pressure airflow at the port of the dust suction nozzle 7, and the powder scattered from the opening of the powder spraying room 1 to the outside is absorbed into the aggregate box 5 for collection, so as to realize the recycling of the powder.
[0029] An elastic baffle 15 is fixed to the inner wall of the avoidance hole 14, and the spray gun 61 passes through the elastic baffle 15. The elastic baffle 15 can be felt. By setting the elastic baffle 15, the opening area of the avoidance hole 14 can be reduced, effectively reducing the amount of powder drifting from the avoidance hole 14 to the outside, and it will not affect the up and down movement of the spray gun 61.
[0030] A filter screen 13 is fixed at the discharge port 12 , and the powder in the collecting tank 11 can be preliminarily filtered by setting the filter screen 13 .
