[0026] Example

[0027] like Figure 1-6 As shown, a powder mixing device that can prevent accumulation includes a housing 1. A discharge pipe 2 is fixedly connected to the lower surface of the housing 1. A feeding hopper 3 is fixedly connected to the outer surface of the discharge pipe 2. A first motor 4 is fixedly connected to the middle of the back of the feeding hopper 3. A first rotating rod 5 is fixedly connected to the output end of the first motor 4. A sleeve 6 is snapped into the middle of the outer surface of the first rotating rod 5. A feeding plate 7 is fixedly connected to the outer surface of the sleeve 6. A top cover 8 is installed on the upper surface of the housing 1. A second motor 9 is fixedly connected to the middle of the upper surface of the top cover 8. A second rotating rod 10 is fixedly connected to the output end of the second motor 9. A connecting rod 11 is fixedly connected to one end of the second rotating rod 10. A spiral conveying blade 12 is fixedly connected to the bottom of the outer surface of the connecting rod 11.

[0028] In practical use, through the arrangement of the feeding bin 3, the first rotating rod 5, the feeding plate 7, the second rotating rod 10, and the spiral conveyor blade 12, the opening of the housing 1 gradually narrows from top to bottom, which can better discharge the powder and reduce internal residue. Multiple feeding plates 7 are evenly fixed on the outer surface of the sleeve 6 in a circumferential array. The middle part of the first rotating rod 5 has a square structure, which facilitates the clamping of the sleeve 6, allowing the feeding plates 7 to be replaced and maintained after long-term use. The connecting rod 11 is fixed to one end of the second rotating rod 10, and the spiral conveyor blade 12 on its surface... 2 is installed inside the discharge pipe 2. When the second motor 9 drives the second rotating rod 10 to rotate, the connecting rod 11 drives the spiral conveyor blade 12 to rotate accordingly, thereby cleaning and scraping the powder on the inner wall of the discharge pipe 2, avoiding the phenomenon of material accumulation caused by blockage of the inner wall of the discharge pipe 2. At the same time, the first motor 4 drives the first rotating rod 5 to rotate, thereby causing the discharge plate 7 to push the powder inside the discharge bin 3 to move downward, assisting the powder discharge operation, avoiding the situation where excessive powder accumulation leads to blockage and difficulty in discharge, thus enhancing the output effect and ensuring the discharge progress.

[0029] In this embodiment, a first support rod 13 is fixedly connected to one side of the outer surface of the feeding bin 3, and a transparent baffle 14 is rotatably connected to the outer surface of the first support rod 13. The transparent baffle 14 is rotatably connected to the first rotating rod 5.

[0030] In practical use, the transparent baffle 14 blocks the opening on the front of the feeding bin 3 through the first support rod 13, supports the first rotating rod 5, and allows the staff to observe the feeding process of the powder inside the feeding bin 3 from the outside. If a blockage occurs, it can be adjusted in time.

[0031] In this embodiment, a connecting block 15 is fixedly connected to one side of the outer surface of the transparent baffle 14 and the feeding bin 3, and a bolt 16 is threadedly connected to the inside of the connecting block 15.

[0032] In practical use, by setting up connecting blocks 15 and bolts 16, when the transparent baffle 14 is closed, the bolts 16 are threaded into the interior of the corresponding two connecting blocks 15, thereby fixing the transparent baffle 14. When it is necessary to inspect and maintain the internal components of the discharge bin 3 or to clean the discharge bin 3, the bolts 16 can be removed to open the transparent baffle 14, which increases the convenience of use.

[0033] In this embodiment, a fixing rod 17 is fixedly connected to the outer surface of the second rotating rod 10, a stirring blade 18 is fixedly connected to the outer surface of the fixing rod 17, and a scraper 19 is fixedly connected to one end of the fixing rod 17.

[0034] In practical use, the stirring blade 18 and scraper 19 are set up, and the fixed rod 17 supports the stirring blade 18 and scraper 19. When the second rotating rod 10 rotates under the action of the second motor 9, the stirring blade 18 stirs and mixes the powder inside the shell 1, increases the movement between materials, and makes the stirring more uniform and thorough, thus enhancing the stirring effect and efficiency. The scraper 19 rotates with the rotation of the second rotating rod 10 and the fixed rod 17, thereby scraping off the powder adhering to the inner wall of the shell 1, avoiding waste and making it easier to clean the device after use.

[0035] In this embodiment, a second support rod 20 is fixedly connected to the top of the outer surface of the housing 1, and a bracket 21 is rotatably connected to the outer surface of the second support rod 20.

[0036] In practical use, the bracket 21 is rotatably connected to the outer surface of the second support rod 20 to support the adjusting rod 22.

[0037] In this embodiment, an adjusting rod 22 is threadedly connected to the top of the outer surface of the bracket 21, and a pressure block 23 is fixedly connected to one end of the adjusting rod 22. A limit ring 24 is fixedly connected to the edge of the upper surface of the top cover 8.

[0038] In practical use, by setting the pressure block 23, rotating the adjusting rod 22 causes the pressure block 23 at its bottom to move downward and contact the top cover 8, thereby limiting and fixing the top cover 8 to prevent it from shaking out during device operation, increasing the safety of device use. The limiting ring 24 prevents the top cover 8 from rotating on its own, thus enhancing stability. At the same time, it makes the installation and disassembly of the top cover 8 more convenient, facilitating the inspection and maintenance of device components and saving costs.

[0039] In this embodiment, a third support rod 25 is fixedly connected to one side of the upper surface of the top cover 8, and a cover plate 26 is rotatably connected to the outer surface of the third support rod 25.

[0040] In practical use, the cover plate 26 is rotatably connected to the outer surface of the third support rod 25, making it easy to open and close. It can block the opening on the surface of the top cover 8 to prevent external dust from entering. When the cover plate 26 is opened, it is convenient to convey powder into the housing 1 without having to open the top cover 8 again, saving time and speeding up work efficiency.

[0041] In this embodiment, a connecting ear 27 is fixedly connected to the upper surface of the cover plate 26, a hydraulic rod 28 is rotatably connected to the inner side of the connecting ear 27, and a support plate 29 is rotatably connected to one end of the hydraulic rod 28. The support plate 29 is fixedly connected to the top cover 8.

[0042] In practical use, the hydraulic rod 28 is configured such that one end of the hydraulic rod 28 is connected to the cover plate 26 via the connecting lug 27, and the other end is rotatably connected to the inner side of the support plate 29. When the output end of the hydraulic rod 28 extends or retracts, it can drive the cover plate 26 to move, automatically opening and closing, making the operation simple and convenient.

[0043] Working principle: In use, the top cover 8 is placed on the upper surface of the housing 1, the rotating bracket 21 is moved above the top cover 8, and the adjusting rod 22 is rotated to fix the pressure block 23 to the top cover 8. The limiting ring 24 prevents the top cover 8 from rotating on its own. The output end of the hydraulic rod 28 retracts, driving the cover plate 26 to open the feed port L, conveying the powder into the interior of the housing 1. The second motor 9 drives the second rotating rod 10 to rotate, the stirring blade 18 stirs and mixes the powder inside the housing 1, and the scraper 19 scrapes off the powder adhering to the inner wall of the housing 1. Meanwhile, the connecting rod 11 drives the spiral conveyor blade 12 to clean and scrape the powder on the inner wall of the discharge pipe 2, avoiding the accumulation of material caused by blockage on the inner wall of the discharge pipe 2. After stirring, the discharge operation is carried out. The first motor 4 drives the first rotating rod 5 to rotate, causing the discharge plate 7 to push the powder inside the discharge bin 3 downward, avoiding the situation where excessive powder accumulates and causes blockage and difficulty in discharge. The output effect is enhanced. The transparent baffle 14 makes it easy for the staff to observe the discharge process of the powder inside the discharge bin 3 from the outside, and can make timely adjustments when blockage occurs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
