Technical Field
[0001] This utility model relates to the field of flour processing technology, specifically to a detachable mixer for flour processing. Background Technology
[0002] Flour is an essential ingredient in most pasta products. Before shaping, flour needs to be mixed, thus requiring an easily detachable flour mixing device. However, existing easily detachable flour mixing devices have certain shortcomings. Firstly, ordinary easily detachable flour mixing devices typically use a scraper to scrape flour off the inner wall of the mixing device during mixing. However, over time, the scraper wears down, widening the gap between the scraper and the inner wall of the mixing device. This prevents the flour adhering to the inner wall from being fully mixed. Secondly, the flour is not broken up before mixing, causing clumps of flour to form inside the mixing device, resulting in insufficient mixing later on.
[0003] A flour mixing device with easy disassembly, authorized by announcement number CN218736859U, includes a mixing drum. A top cover plate is threaded to the upper end of the mixing drum. A servo motor is fixedly installed on the upper end of the top cover plate. An inclined pipe is connected to the outside of the mixing drum near one side. A dispersing box is connected to the upper end of the inclined pipe. A feed hopper is connected to the upper end of the dispersing box. A filter screen is fixedly installed inside the feed hopper. Two motors are horizontally fixedly installed on the outside of the dispersing box. Two dispersing rollers are arranged inside the dispersing box, and one end of each roller is fixedly connected to the output shaft of the two motors. The output shaft of the servo motor passes through the lower end of the top cover plate, and a rotating rod is fixedly installed at the bottom end of the output shaft. This easy-to-disassemble flour mixing device facilitates flour mixing and dispersing, resulting in more thorough mixing.
[0004] As shown in the above equipment, the existing detachable mixer for flour processing is convenient for mixing flour and can break it up to make the mixing more thorough. However, during the mixing process, the flour tends to stick to the inner wall of the mixing tank and cannot be fully stirred by the mixing rack, which will cause waste of raw materials. Moreover, after long-term use, the flour stuck to the tank wall will dry and harden, increasing the difficulty and workload of cleaning the equipment. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] See Figures 1-7 This utility model provides the following two technical solutions:
[0028] First embodiment: A detachable mixer for flour processing, comprising a mixing bowl 1, and further comprising:
[0029] The stirring structure 4 is located inside the mixing tank 1 and is used to stir and process the flour inside the mixing tank 1.
[0030] The material conveying and screening structure 8 is located on one side of the mixing tank 1 and is used for the input and screening of flour.
[0031] The inner wall of the mixing tank 1 is provided with a threaded groove 6. A cover 2 is threadedly connected to the inner wall of the threaded groove 6.

[0032] The stirring structure 4 includes a connecting plate 41, which is positioned above the stirring tank 1. A connecting frame 42 is fixedly connected to the top of the connecting plate 41. A drive motor 43 is fixedly installed at one end of the connecting frame 42. A bevel gear A44 is fixedly and rotatably connected to the output end of the drive motor 43. A bevel gear B45 meshes with the outer wall of the bevel gear A44. A wall scraping assembly 46 is provided below the bevel gear B45. A rotating shaft A49 is fixedly connected to the bottom end of the bevel gear B45. A rotating rod 47 is connected to the outer wall of the rotating shaft A49 by a clockwise thread. A stirring frame 48 is fixedly connected to the outer wall of the rotating rod 47.
[0033] The wall scraping assembly 46 includes a turntable 461, which is rotatably connected to the bottom end of the connecting plate 41. A connecting shaft 462 is fixedly connected to the top end of the turntable 461 by bolts. A bevel gear C463 is fixedly connected to the top end of the connecting shaft 462. The bevel gear C463 meshes with the bevel gear A44. A wall scraping frame 464 is fixedly connected to the outer wall of the turntable 461. A hydraulic rod 466 is fixedly installed on the inner wall of the wall scraping frame 464. A wall scraping flexible plate 467 is fixedly connected to one end of the hydraulic rod 466. A storage groove 468 is formed at the beginning of the outer wall of the wall scraping frame 464. A circular groove hinge rod 465 is hinged to the inner wall of the storage groove 468. The inner wall of the circular groove hinge rod 465 is slidably connected to the bottom end of the wall scraping flexible plate 467.
[0034] This detachable mixer for flour processing features a mixing structure 4. A drive motor 43 rotates a bevel gear A44, which, through meshing, drives the mixing frame 48 and the scraper frame 464 respectively. The former achieves all-around mixing of the flour, ensuring uniform mixing and improving mixing efficiency and quality; the latter continuously scrapes flour from the inner wall of the mixing tank 1, preventing residue from affecting mixing and product quality. Furthermore, the mixing structure 4 uses bolted connections in multiple places, facilitating equipment maintenance, cleaning, and component replacement, reducing maintenance costs, ensuring hygiene standards in flour processing, and extending the equipment's service life.
[0035] The second embodiment differs from the first embodiment in that the material conveying and screening structure 8 includes a material conveying box 81, which is located on one side of the mixing tank 1. A material conveying pipe 82 is fixedly connected to the top of the material conveying box 81. A servo motor 83 is fixedly installed on the outer wall of the material conveying box 81. A rotating shaft B84 is provided at the output end of the servo motor 83. An eccentric wheel 85 is fixedly installed on the outer wall of the rotating shaft B84. A crank rocker arm 86 is hinged to the inner wall of the eccentric wheel 85. A screening plate 87 is hinged to the top of the crank rocker arm 86. A limiting groove 88 is provided on the inner wall of the material conveying box 81. The inner wall of the limiting groove 88 is slidably connected to the screening plate 87.
[0036] This detachable mixer for flour processing is equipped with a feeding and sieving structure 8. After the flour enters the feeding box 81 from the feeding pipe 82, the servo motor 83 drives the rotating shaft B84 to rotate the eccentric wheel 85. The crank rocker arm 86 drives the sieving plate 87 to reciprocate within the limiting slide groove 88, removing lumps and impurities, ensuring that the flour entering the mixing tank 1 is pure and has uniform particles. This allows the mixing structure 4 to mix the flour more efficiently, avoiding problems such as uneven mixing and prolonged mixing time caused by lumps, ensuring smooth mixing, saving processing time, and improving overall production efficiency.
[0037] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0038] When in use, the detachable mixer for flour processing operates. Flour enters the feed box 81 through the feed pipe 82. The servo motor 83 drives the rotating shaft B84 to rotate, which in turn drives the eccentric wheel 85 to rotate. The eccentric wheel 85 drives the sieve plate 87 to slide up and down in the limiting slide groove 88 through the crank rocker arm 86, thereby sieving the flour. The sieved flour then enters the mixing tank 1 through the feed pipe 7. Inside the mixing tank 1, the drive motor 43 drives the bevel gear A44 to rotate. The bevel gear A44 meshes with the bevel gears B45 and C463, causing the bevel gear B45 to drive the rotating shaft A49 to rotate, which in turn causes the rotating rod 47 and the mixing frame 48 to mix the flour. At the same time, the bevel gear C463 drives the rotating shaft 462 and the turntable 461 to rotate, and the scraper frame 464 on the turntable 461 rotates accordingly. The hydraulic rod 466 on the scraper frame 464 can push the scraper plate 467 to press tightly against the inner wall of the mixing tank 1. The circular groove hinge rod 465 assists the movement of the scraper plate 467 to achieve the scraping function and prevent the flour from sticking to the wall. After mixing is completed, the flour is discharged from the discharge pipe 9. Rotating the rotating handle 3 can unscrew the cover 2 to disassemble and maintain the mixing structure 4. The support frame 5 provides stable support for the entire equipment, and the protective cover 10 protects the internal components.
