The blower control device for removing metal particles and dust from a 3D printer, by setting up a dust treatment device, the dust generated inside the housing and the splashed metal particles. During printing, the generated dust will float upward due to its light mass. When the dust floats to the top inside the housing, the drive motor drives the exhaust fan to rotate, and the exhaust fan extracts the floating dust to the outside of the housing, preventing the dust from accumulating inside the housing and causing excessive dust to wrap the metal model, which affects the outside staff's observation of the metal model printing progress through the transparent glass;

Then rotate the rotating shaft to make the square tube tilt, and at the same time make the square tube parallel to the rotating plate, with the square tube and the rotating plate being on the same straight line. Then the blower starts to generate air flow, and the air flow blows towards the inclined rotating plate, with the air flow direction being parallel to the inclined rotating plate.

At the same time, the second gear drives the third gear to rotate through the reversing gear, making the square tube rotate synchronously and in the same direction as the rotating plate. Then the staff takes out the model. At this time, the blower generates air flow and starts to clean the metal particles inside the housing.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] Please refer to Figures 1-6 , in this implementation manner:

[0027] A fan control device for removing metal particles and smoke and dust in a 3D printer, including a printer housing 1. Rotating rods 11 are rotatably connected to the side walls on both sides of the inner cavity of the housing 1. A rotating plate 12 is fixedly connected between the two rotating rods 11. A printing base 13 is provided on the rotating plate 12. A smoke and dust treatment device 2 is provided on one side of the housing 1. The smoke and dust treatment device 2 is used to treat the smoke and dust generated during printing. An air flow regulating device 3 is provided below the smoke and dust treatment device 2 on one side of the housing 1. The air flow regulating device 3 is used to change the direction of air flowing into the housing 1. An opening is provided on one side of the housing 1. Two fixed blocks 14 are fixedly connected to one side of the housing 1. A round rod 15 is rotatably connected between the two fixed blocks 14. A baffle 16 is fixedly connected to the outer circle of the round rod 15. A first square through groove 17 is provided on the baffle 16. A transparent glass is provided on the side wall of the first square through groove 17. A handle 18 is fixedly connected to one side of the baffle 16.

[0028] The present invention is used to handle the soot and splashed metal particles generated inside the housing 1 when 3D printing metal components. During printing, the generated soot will float upward due to its light mass. When the soot floats to the top inside the housing 1, the soot can be processed by the soot treatment device 2 located in the upper part at this time, avoiding the accumulation of soot inside the housing 1, which may cause excessive soot to wrap the metal model and affect the external staff's observation of the metal model printing progress through the transparent glass. During printing, some metal particles splash out. At this time, due to the relatively large weight of the metal particles, the metal particles bounce after hitting the inner wall of the housing 1. When the kinetic energy disappears, they fall on the rotating plate 12 and the printing base 13. After printing is completed, hold the handle 18 and flip the baffle 16 to remove the model from the printing base 13. At the same time, air starts to pass through the air flow regulating device 3 from the other side of the housing 1 into the housing 1. The air flow regulating device 3 adjusts the air flow direction, blowing the metal particles on the rotating plate 12 and the printing base 13 towards the opening until the metal particles are blown out of the housing 1, cleaning the inside of the housing 1 and keeping the printing base 13 and the rotating plate 12 clean, avoiding the metal particles from affecting the next printing of the metal model.

[0029] The soot treatment device 2 includes a circular tube 21. A circular through groove is provided on the housing 1, and the circular tube 21 is fixed on the side wall of the circular through groove. A cross plate 22 is fixedly connected to the side wall of the circular tube 21. A driving motor 23 is fixedly connected to one side of the cross plate. The main shaft of the driving motor 23 penetrates the cross plate 22, and an air extraction fan 24 is fixedly connected to the main shaft of the driving motor 23.

[0030] When the soot generated by printing the model floats above the housing 1, the driving motor 23 drives the air extraction fan 24 to rotate at this time. The air extraction fan 24 extracts the floating soot to the outside of the housing 1, playing a role in exhausting the smoke inside the housing 1. At the same time, the air extraction fan 24 extracts the heat generated inside the housing 1, playing a role in cooling the inside of the housing 1, which is beneficial to the rapid cooling of the model, beneficial to improving the printing speed of the metal model, and improving work efficiency.

[0031] On both sides of the printing base 13 on the rotating plate 12, a plurality of inclined grooves 19 are provided. The plurality of inclined grooves 19 are connected to each other. On both sides of the upper surface of the rotating plate 12 away from the inclined grooves 19 of the printing base 13, triangular blocks 191 are fixedly connected.

A second square through groove is provided on one side of the housing 1. The air flow regulating device 3 is located on the inner wall of the square through groove. The air flow regulating device 3 includes a square pipe 31. Rotating shafts 32 are fixedly connected to both sides of the square pipe 31. The rotating shafts 32 are rotatably connected to the side walls of the second square through groove. One end of the square pipe 31 communicates with a blower. An elastic sealing film 33 is fixedly connected between the side wall of the square pipe 31 and the side wall of the second square through groove. The two rotating shafts 32 penetrate through the housing 1. A power device 4 is provided on one side of one of the rotating shafts 32. The power device 4 is used to drive the rotating shaft 32

[0032] After the metal particles lose kinetic energy, they fall on the rotating plate 12 and the printing base 13. Under the action of the inclined grooves 19 and the side walls of the triangular blocks 191, the metal particles slide and gather at the bottom of the inclined grooves 19. After printing, at this time, hold the handle 18 and rotate the baffle 16 to open the housing 1 and take out the model. Then rotate the rotating plate 12 to make the rotating plate 12 and the printing base 13 inclined, with the side near the opening being lower and the side near the second square through groove being raised, so that the metal particles gathered at the bottom of the inclined grooves 19 roll along the inclined grooves 19, and the metal particles roll out of the interior of the housing 1 through the opening. Then rotate the rotating shaft 32 to make the square pipe 31 inclined, and at the same time make the square pipe 31 parallel to the rotating plate 12, and the square pipe 31 and the rotating plate 12 are on the same straight line. Then the blower starts to generate air flow. The blower is a prior art and will not be elaborated here. The air flow blows towards the inclined rotating plate 12, and the air flow direction is parallel to the inclined rotating plate 12. Under the blowing of the air flow, the metal particles roll and accelerate, and at the same time prevent the metal particles from sticking to the rotating plate 12, which is beneficial to further cleaning the rotating plate 12 and reducing the residue of metal particles.

[0033] A sliding groove 193 is provided on the outside of the housing 1. The power device 4 includes a slider 41. The slider 41 is located in the sliding groove 193 and is slidably connected to the housing 1. A spring 42 is fixedly connected between one side of the slider 41 and the side wall of the sliding groove 193. A rack 43 is fixedly connected to one side of the slider 41.

A third gear 45 is fixedly connected to the outer circle of the rotating shaft 32. The third gear 45 meshes with the reversing gear 44. A vertical plate 46 is provided on one side of the housing 1. An elastic traction rope 47 is fixedly connected to one side of the rack 43. The elastic traction rope 47 penetrates through the vertical plate 46. A connecting plate 48 is fixedly connected to one side of the baffle 16. The elastic traction rope 47 is fixedly connected to the connecting plate 48.

[0034] When the baffle 16 is rotated, the baffle 16 pulls the traction rope 47, the traction rope 47 pulls the rack 43 to slide, the spring 42 deforms, the rack 43 drives the second gear 413 to rotate through the first gear 403, so that the rotating plate 12 rotates and tilts. At the same time, the second gear 413 drives the third gear 45 to rotate through the reversing gear 44, so that the square tube 31 rotates in the same direction as the rotating plate 12 synchronously. After that, the staff takes out the model. At this time, the blower generates air flow and starts to clean the metal particles inside the housing 1. When the model is taken out, under the movement of the spring 42 resetting, the rack 43 is pulled back to its original position, and at the same time, the baffle 12 is reset to cover the housing 1, and the rotating plate 12 and the square tube 31 return to the horizontal, which saves more time and improves the use efficiency of the 3D printer.

[0035] The working principle and usage process of the present invention: The soot and splashed metal particles generated inside the housing 1. During printing, the generated soot will float upward due to its light mass. When the soot floats to the top inside the housing 1, at this time, the driving motor 23 drives the exhaust fan 24 to rotate, and the exhaust fan 24 extracts the floating soot to the outside of the housing 1. After printing is completed, the baffle 16 is rotated, the baffle 16 pulls the traction rope 47, the traction rope 47 pulls the rack 43 to slide, the spring 42 deforms, the rack 43 drives the second gear 413 to rotate through the first gear 403, so that the rotating plate 12 rotates and tilts. At the same time, the second gear 413 drives the third gear 45 to rotate through the reversing gear 44, so that the square tube 31 rotates and tilts in the same direction as the rotating plate 12 synchronously. After that, the staff takes out the model. At this time, the blower generates air flow and starts to clean the metal particles inside the housing 1.
