[0003] In the prior art, when the additive manufacturing device is running, dust is easily generated during the generation of the additive inside it. And since the temperature inside the device needs to be controlled during operation, a ventilation fan is required to extract the hot air inside the additive manufacturing device. However, the air inside the additive manufacturing device contains dust, which is likely to accumulate inside the exhaust fan, thus blocking the exhaust fan and affecting its operation.

[0024] Embodiment 1

[0025] Refer to Figures 1-8, an additive manufacturing device, including a printer body 1. One side of the printer body 1 is rotatably connected to a door panel 2 through a rotating shaft. The inner wall of the printer body 1 is fixedly connected with a guide rail 3. One side of the guide rail 3 is slidably connected with a placement plate 4. The inner wall of the printer body 1 is fixedly connected with a sliding rod 5. One side of the sliding rod 5 is slidably connected with a print head 6. The top of the print head 6 is fixedly connected with a transfer pipe. One side of the printer body 1 is provided with an installation groove. The inner wall of the installation groove is fixedly connected with a blower housing 7. The inner wall of the blower housing 7 is fixedly connected with an exhaust fan 8. The inner wall of the blower housing 7 is fixedly connected with a partition net 9. One side of the drive shaft of the exhaust fan 8 is fixedly connected with a first gear 10. The top of the first gear 10 is engaged with a second gear 11. One side of the second gear 11 is fixedly connected with a third gear 12. The top of the installation groove is provided with a chute. The inner wall of the chute is slidably connected with an L-shaped plate 17. The bottom of the L-shaped plate 17 is fixedly connected with a fixing plate 13. The third gear 12 is rotatably connected to one side of the fixing plate 13. The bottom of the third gear 12 is engaged with a fourth gear 14. One side of the fourth gear 14 is fixedly connected with a round block 15. The round block 15 is rotatably connected to the center of the partition net 9. The top of the round block 15 is fixedly connected with a cleaning rod 16. The cleaning rod 16 is attached to the side of the partition net 9 away from the exhaust fan 8.

[0026] To solve the problem that the dust generated inside the additive manufacturing device is likely to block the exhaust fan 8, when 3D printing is required, the device can be debugged, and then the printer body 1 is started. The printing material is transferred to the print head 6 through the transfer pipe and extruded onto the placement plate 4 as an additive. At the same time, the sliding rod 5 can adjust the position of the print head 6, thus facilitating the production of the additive into a specified shape. When it is necessary to cool the inside of the printer body 1, the exhaust fan 8 provided in the blower housing 7 can be started. When the exhaust fan 8 is started, the air inside the printer body 1 is drawn out to the outside of the blower housing 7. By setting the partition net 9, the dust in the air flow can be filtered, and the dust is blocked on one side of the partition net 9. When the exhaust fan 8 is started, it drives the first gear 10 provided on one side of the drive shaft to rotate. When the first gear 10 rotates, it drives the second gear 11 engaged above to rotate. Since the size of the second gear 11 is larger than that of the first gear 10, the rotation speed of the second gear 11 is lower than that of the first gear 10. The third gear 12 provided on one side of the second gear 11 also rotates together with the second gear 11. When the third gear 12 rotates, it drives the fourth gear 14 below to rotate, so that the rotation speed of the fourth gear 14 is less than that of the first gear 10. Therefore, when the fourth gear 14 rotates, it drives the round block 15 and the cleaning rod 16 on one side to rotate together. Since the cleaning rod 16 is provided on the side of the partition net 9 away from the exhaust fan 8, the cleaning rod 16 can scrape the dust on the side of the partition net 9 away from the exhaust fan 8 when rotating, preventing the accumulation of dust on one side of the partition net 9.

[0027] Reference Figure 5 At the bottom of the installation groove, a dropping groove 18 is formed, at the bottom of the dropping groove 18, a placing groove is formed, an inner wall of the placing groove is provided with a collecting box 19, and one side of the bottom of the dropping groove 18 is fixedly connected with a first inclined block 20.

[0028] By arranging the dropping groove 18 at the bottom of the installation groove, after the dust is scraped off, it can fall into the inside of the dropping groove 18 by gravity, and through the guidance of the dropping groove 18, the dust can fall into the collecting box 19. By arranging the inclined block, it is beneficial to guide the dust into the inside of the collecting box 19.

[0029] Reference Figure 5 At the top end of the inner wall of the placing groove, a guiding block 21 is fixedly connected. An inner wall of the guiding block 21 is slidably connected with a sealing plate 22. The sealing plate 22 is arranged at the top of the collecting box 19, and one side of the sealing plate 22 is fixedly connected with a handle 23.

[0030] By arranging the guiding block 21 at the top of the placing groove, when needed, the handle 23 can be pulled to pull the sealing plate 22 to one side. The guiding block 21 can limit the moving track of the sealing plate 22. After the sealing plate 22 is pulled open, the top end of the collecting box 19 can be opened, facilitating the collection of dust. When it is necessary to close the collecting box 19, the handle 23 and the sealing plate 22 can be pushed to slide on the inner wall of the guiding block 21, thereby closing the top end of the collecting box 19.

[0031] Reference Figure 5 On the other side of the bottom of the dropping groove 18, a second inclined block 24 is fixedly connected. The second inclined block 24 and the first inclined block 20 are symmetrically distributed, and the bottom of the second inclined block 24 is attached to the top end of the sealing plate 22.

[0032] By arranging the second inclined block 24 at the bottom of the dropping groove 18, when the sealing plate 22 is opened to one side, it is convenient to push the impurities at the top end of the sealing plate 22 into the collecting box 19 through the second inclined block 24, facilitating the centralized collection of dust and impurities and preventing the remaining dust from accumulating on the sealing plate 22.

[0033] Reference Figure 1 On one side of the printer body 1, a dust-proof plate 25 is rotatably connected through a rotating shaft. The dust-proof plate 25 is arranged on one side of the fan housing 7, and a pulling block is fixedly connected to the bottom of the dust-proof plate 25.

[0034] By arranging the dust-proof plate 25, dust outside the printer body 1 can be prevented from entering the inside of the fan housing 7, thereby protecting the exhaust fan 8 inside the fan housing 7.

[0035] Reference Figure 1, a bottom plate 26 is fixedly connected to the bottom of the printer body 1, and support legs 27 are fixedly connected to the bottom of the bottom plate 26. Four groups of the support legs 27 are provided and are symmetrically distributed at the bottom of the bottom plate 26.

[0036] By providing the bottom plate 26 and the support legs 27 at the bottom of the printer body 1, it is beneficial to provide stable support for the bottom of the printer body 1 through the support legs 27. At the same time, gaskets are provided at the bottom of the support legs 27 to provide a slight damping effect.

[0037] Working principle: To solve the problem that the dust generated inside the additive manufacturing equipment is likely to clog the exhaust fan 8, the prior art can directly use 3D printing to manufacture the additive into a specified shape. When it is necessary to cool the inside of the printer body 1, the exhaust fan 8 provided inside the fan housing 7 can be started. When the exhaust fan 8 starts, the air inside the printer body 1 will be drawn outwards from the fan housing 7. By setting the partition net 9, the dust in the air flow can be filtered, so that the dust is blocked on one side of the partition net 9. When the exhaust fan 8 starts, it will drive the first gear 10 provided on one side of the drive shaft to rotate. When the first gear 10 rotates, it will drive the second gear 11 meshed above to rotate. Since the size of the second gear 11 is larger than that of the first gear 10, the rotation speed of the second gear 11 will be lower than that of the first gear 10. The third gear 12 provided on one side of the second gear 11 will also rotate together with the second gear 11. When the third gear 12 rotates, it will drive the fourth gear 14 below to rotate, so that the rotation speed of the fourth gear 14 is less than that of the first gear 10. Therefore, when the fourth gear 14 rotates, it will drive the round block 15 and the cleaning rod 16 on one side to rotate together. Since the cleaning rod 16 is provided on the side of the partition net 9 away from the exhaust fan 8, the cleaning rod 16 can scrape the dust on the side of the partition net 9 away from the exhaust fan 8 when it rotates, preventing dust accumulation on one side of the partition net 9. By setting the guiding block 21 at the top of the placement groove, when needed, the handle 23 can be pulled to pull the sealing plate 22 to one side, and the guiding block 21 can limit the moving track of the sealing plate 22. After the sealing plate 22 is pulled open, the top of the collection box 19 can be opened, facilitating the collection of dust. When the sealing plate 22 is opened to one side, it is convenient to push the impurities at the top of the sealing plate 22 into the collection box 19 through the second inclined block 24, facilitating the centralized collection of dust and impurities to prevent the remaining dust from accumulating on the sealing plate 22. By setting the dropping groove 18 at the bottom of the installation groove, after the dust is scraped off, it can fall into the inside of the dropping groove 18 by gravity. Through the guidance of the dropping groove 18, the dust can fall into the collection box 19. By setting the inclined block, it is beneficial to guide the dust into the collection box 19. When it is necessary to close the collection box 19, the handle 23 and the sealing plate 22 can be pushed to slide on the inner wall of the guiding block 21, thereby closing the top of the collection box 19. By setting the dust-proof plate 25, the dust outside the printer body 1 can be prevented from entering the inside of the fan housing 7, thus protecting the exhaust fan 8 inside the fan housing 7.

[0038] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
