[0017] See also Figure 1-5The present embodiment is a metal powder spraying device with a powder recovery mechanism, comprising a box body 1, a box door is provided on one side of the box body 1, a powder recovery slot 5 is provided at the bottom of the box body 1, a long strip chamber 12 is provided on the top surface of the box body 1, four air vents 13 are provided at the bottom of the chamber 12 along the length direction, a filter cartridge 6 is installed at each air vent 13, and the filter cartridge 6 is used to collect the powder diffused in the box body 1, two air exhaust ports are provided on the top of the chamber 12, and an exhaust fan 9 is installed at each air exhaust port; a suspension mechanism is also installed on the top of the box body 1, and the suspension mechanism includes a rotating shaft, a rotating shaft, and a rotating shaft. A turntable 7 is fixedly mounted at the bottom end of the shaft, a circle of hooks is installed on the ground of the turntable 7, the rotating shaft is rotatably connected to the box body 1, the top end of the rotating shaft passes through the box body 1 upward and is equipped with a driven sprocket 8, a driving mechanism 10 is provided on the top of the box body 1, the driving mechanism 10 is connected to the sprocket to drive the turntable 7 to rotate; a group of powder spraying mechanisms are installed on both sides of the box body 1, the powder spraying mechanism includes a nozzle 2 and a pump 4, the inner end of the nozzle 2 is aimed at the workpiece, the outer end of the nozzle 2 is connected to the output end of the pump 4, the input end of the pump 4 is equipped with a suction pipe 15, the suction pipe 15 passes through the box body 1 and is inserted into the bottom of the powder recovery tank 5.

[0018] Furthermore, three vibration motors 14 are installed on the inner bottom surface of the chamber 12 .

[0019] Furthermore, the filter cartridge 6 comprises an inner cartridge, the bottom of which is closed, the top of which is connected to the chamber 12, the side wall of which is covered with air holes, and a circle of filter paper is installed on the outside of the inner cartridge.

[0020] Furthermore, the filter paper is provided with a plurality of folds along the circumferential direction to increase the filtering area.

[0021] Furthermore, the driving mechanism 10 includes a motor and a reducer, the output end of the motor is connected to the input end of the reducer, the output end of the reducer is equipped with a driving sprocket 11, and the driving sprocket 11 is connected to the driven sprocket 8 through a chain transmission.

[0022] Furthermore, the nozzle 2 mechanism is provided with three nozzles 2, and the three nozzles 2 are arranged from top to bottom to spray different positions of the workpiece respectively.
