[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1-Figure 5 The utility model provides an embodiment: a powder recovery device for powder coating production, comprising a base 1, a conveyor belt 3 is arranged in the base 1, a top cover 2 is fixedly connected to the top wall of the base 1, transparent glass plates are fixedly connected on both sides of the top cover 2, and a feed barrel 9 is connected to the rear side of the top wall of the top cover 2.

[0024] During the production of powder coatings, when the powder needs to be transported to different processes, the staff can pour the powder into the feed barrel 9. When the powder enters the feed barrel 9, it will fall onto the conveyor belt 3. At this time, the powder on the conveyor belt 3 can be transported and transferred by starting the conveyor belt 3, and the transparent glass plates on both sides of the top cover 2 can facilitate the staff to observe the transportation of the powder on the conveyor belt 3.

[0025] Reference Figure 1-Figure 5 The front side of the top wall of the feed barrel 9 is fixedly connected to a drive motor 10, the output end of the drive motor 10 passes through the inner top wall of the feed barrel 9 and is fixedly connected to a pinion 21, the rear side of the pinion 21 is engaged with a gear ring 22, the gear ring 22 is rotatably connected to the inner top wall of the feed barrel 9, and the bottom wall of the gear ring 22 is fixedly connected to a plurality of scraper rods 23, the plurality of scraper rods 23 are evenly distributed in a ring shape, and the plurality of scraper rods 23 are all L-shaped rods and abut against the inner wall of the feed barrel 9.

[0026] When the powder falls onto the conveyor belt 3 through the feed barrel 9, the driving motor 10 is started to drive the pinion 21 fixed at the output end to rotate. When the pinion 21 rotates, it can drive the outer peripheral meshing gear ring 22 to rotate. When the gear ring 22 rotates, it can drive the multiple scraper rods 23 fixed at the bottom end to rotate. Since the scraper rods 23 are in contact with the inner wall of the feed barrel 9, the scraper rods 23 can scrape off the powder adhering to the inner wall of the feed barrel 9, thereby reducing the loss of powder during the transportation process.

[0027] Reference Figure 1-Figure 5A chamber 11 is provided on one side of the front of the base 1, and a collecting chamber 20 is provided on the lower part of the base 1. A collecting box 8 is slidably connected to the collecting chamber 20, and one side of the collecting box 8 passes through the side wall of the base 1. A runner 7 is rotatably connected to the front of one side of the base 1. One end of the runner 7 passes through the chamber 11 and is fixedly connected to a bevel gear 12. A bevel gear 2 13 is engaged with the lower side of the bevel gear 12. The bevel gear 2 13 is rotatably connected to the bottom wall of the chamber 11. The bottom end of the bevel gear 2 13 is fixedly connected to a threaded rod 14. The top of the threaded rod 14 is rotatably connected to the top wall of the chamber 11. A disc is fixed to the bottom end of the threaded rod 14. The diameter of the disc is larger than the diameter of the threaded rod 14. The bottom end of the threaded rod 14 passes through the collecting chamber 20 and is threadedly connected to a movable plate 15. The movable plate 15 passes through a limiting rod 19 away from the side of the threaded rod 14. The top of the limiting rod 19 is fixedly connected to the top wall of the collecting chamber 20. The movable plate 1 5 is slidably connected to a plurality of connecting rods 16 inside, and the plurality of connecting rods 16 are T-shaped rods. The top ends of the plurality of connecting rods 16 all penetrate the top wall of the movable plate 15 and are fixedly connected to a scraper 18 with a triangular cross-section. The bottom end of the scraper 18 is fixedly connected to a plurality of springs 17. The bottom ends of the plurality of springs 17 are fixedly connected to the movable plate 15. The plurality of springs 17 are all arranged on the outer periphery of the connecting rod 16 (the springs 17 and the connecting rods 16 are arranged in a one-to-one correspondence); the dust collection assembly is arranged on the upper side of the base 1, and the dust collection assembly is used to extract and recover the raised dust. The dust collection assembly includes a top cover 2, the top wall of the top cover 2 is fixedly connected to an air inlet shell 24, the front side of the air inlet shell 24 is fixedly connected to a filter plate 25, the top end of the air inlet shell 24 is connected to a plurality of exhaust pipes 4, the top ends of the plurality of exhaust pipes 4 all penetrate the top wall of the top cover 2 and are connected to a connecting pipe 5, one end of the connecting pipe 5 is connected to a pump body 6, and the output end of the pump body 6 penetrates into the chamber 11.

[0028] By starting the pump body 6, the interior of the connecting tube 5 can be extracted. Since the end of the connecting tube 5 away from the pump body 6 is connected to multiple exhaust pipes 4 and the bottom end of the exhaust pipe 4 is connected to the air inlet shell 24, the air inlet area of ​​the air inlet shell 24 can be extracted under the action of the pump body 6. After the powder falls onto the surface of the conveyor belt 3 through the feed barrel 9, part of the powder will be lifted into the air under the action of the impact force. Therefore, the raised dust can be sucked into the air inlet shell 24 through the pump body 6, and the sucked dust can be sent into the collection chamber 20 and fall into the collection box 8 for storage through the action of the exhaust pipe 4 and the connecting tube 5. At the same time, the air inlet shell 24 can be filtered under the action of the filter plate 25 to prevent debris from entering.

[0029] The powder that falls on the conveyor belt 3 will be transported and transferred under the action of the conveyor belt 3, because rotating the runner 7 can drive the bevel gear 12 to rotate, and when the bevel gear 12 rotates, it can drive the meshing bevel gear 2 13 and the threaded rod 14 fixed to the middle of the bevel gear 2 13 to rotate, and when the threaded rod 14 rotates, it can drive the connected movable plate 15 to move. Since the movable plate 15 also passes through the limiting rod 19, the movable plate 15 can be limited under the action of the limiting rod 19, thereby preventing the movable plate 15 from rotating, and then the movable plate 15 will move up and down along the threaded rod 14 as the threaded rod 14 rotates. When the movable plate 15 moves, it can be driven by the connecting rod 16 The scraper 18 at the top moves up and down, so the staff can drive the scraper 18 to move up and abut against the lower surface of the conveyor belt 3 by rotating the wheel 7, so that the powder adhering to the conveyor belt 3 can be scraped off and collected in the collection box 8 in the collection chamber 20 for recovery. When the scraper 18 is pressurized, the spring 17 will be compressed. At the same time, the spring 17 can be limited under the action of the connecting rod 16, so as to prevent the spring 17 from bending after being compressed and affecting the normal use of the spring 17. When the spring 17 is pressurized, it will provide an opposite force, which can ensure that the scraper 18 is always in contact with the conveyor belt 3, thereby avoiding the scraper 18 from failing to effectively abut against the conveyor belt 3 after long-term use, thereby ensuring that the scraper 18 can effectively scrape and clean the powder adhering to the conveyor belt 3 for a long time.

[0030] Working principle: In actual use, the powder can be poured onto the surface of the conveyor belt 3 through the feed barrel 9, and by starting the drive motor 10, the pinion 21 can be driven to rotate and the meshing gear ring 22 and the multiple scraping rods 23 fixed at the bottom end of the gear ring 22 can be driven to rotate, so that the powder adhering to the inner wall of the feed barrel 9 can be scraped off. When the powder falls onto the conveyor belt 3, some dust will be raised. At this time, the raised dust can be extracted from the air inlet shell 24 by starting the pump body 6 and sent into the collection chamber 20 through the exhaust pipe 4 and the connecting pipe 5, and then passed through the conveyor belt. 3 can transport and transfer powder coatings, and during the transportation process, some dust will adhere to the conveyor belt 3. At this time, the bevel gear 1 12 and the bevel gear 2 13 can be driven to rotate by the runner 7, thereby driving the threaded rod 14 to rotate and drive the moving plate 15 to drive the scraper 18 to move up and contact and squeeze the conveyor belt 3. When the scraper 18 is pressed, it compresses the spring 17. Therefore, under the action of the spring 17, it can ensure that the scraper 18 is in constant contact with the conveyor belt 3, so that the powder adhered to the conveyor belt 3 can be scraped off to the collection chamber 20 for recovery.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
