Description

Technical Field

[0001] This utility model relates to the field of noodle production technology, and in particular to a powder-sprinkling mechanism for noodle production. Background Technology

[0002] In existing technologies, the industrial production of noodles requires cutting the dough sheets before placing them on a conveyor belt to the next process. However, after cutting, the noodles tend to stick together, affecting the product's appearance. To prevent freshly produced wet noodles from sticking together, flour needs to be sprinkled on them.

[0003] In existing noodle production, flour is fed onto a vibrating screen via a feeding mechanism. The regular vibration of the screen then evenly and meticulously sprinkles the flour onto the surface of the noodles being conveyed on a conveyor belt, thus achieving uniform flour coating.

[0004] However, due to the inherent characteristics of flour, it readily absorbs moisture from the air during long-term storage, leading to clumping. This clumping alters the physical form of the flour, increasing particle size and stickiness. During feeding, it easily accumulates and gets stuck at the feeding inlet, eventually causing blockage. Once the feeding inlet is blocked, operators must stop the machine for cleaning, which not only increases labor costs and intensity but also severely disrupts the production rhythm, resulting in a significant decrease in overall production efficiency. Another problem with flour during the spreading process is its tendency to clog the mesh of the vibrating screen. Clumped flour or larger flour particles may get stuck in the mesh as it passes through. Over time, more and more flour clogs the mesh, severely affecting the spreading effect and causing uneven flour distribution on the noodle surface, further impacting noodle quality. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a flour-sprinkling mechanism for noodle production, which reduces flour moisture absorption and clumping, and blockage of the feeding port and screen, avoids frequent machine shutdowns for cleaning, ensures continuous and stable production, shortens the production cycle, increases output, reduces labor costs and labor intensity, improves production efficiency, and reduces energy and other cost consumption per unit product, thereby improving the economic benefits of the enterprise.

[0006] The objective of this utility model is achieved through the following technical solution: A flour-spreading mechanism for noodle production includes a fixed frame; it also includes a storage box fixedly connected to the fixed frame, a fixed plate fixedly connected to the fixed frame, an anti-caking component and a feeding component installed on the storage box, and a flour-spreading component installed on the fixed plate. The anti-caking component is used to heat the flour, and the feeding component is used to discharge the flour from the storage box. The anti-caking assembly includes a first motor fixedly connected to one side of the storage tank, two sets of stirring racks rotatably connected inside the storage tank, gears fixedly connected to the two sets of stirring racks, and two sets of moisture-proof heating plates fixedly connected to both sides of the storage tank. The two sets of gears mesh with each other, and the first motor is used to drive the stirring racks to rotate.

[0007] In one optional embodiment, the stirring rack is provided with multiple sets of stirring rods, which are arranged in a star-shaped array on the stirring rack, and the stirring rods on two sets of stirring racks are staggered.

[0008] In one optional embodiment, the feeding assembly includes a discharge roller rotatably connected to the inside of the storage box, a second motor fixedly connected to one side of the storage box, and an intermittent component mounted on the discharge roller and the second motor.

[0009] In one optional embodiment, the intermittent component includes an indexing plate fixedly connected to the discharge roller and a cylindrical indexing cam fixedly connected to the output end of a second motor. The second motor drives the indexing plate to rotate by driving the cylindrical indexing cam.

[0010] In one optional embodiment, the powder-spreading assembly includes a first spring fixedly connected to a fixed plate, a sieve plate mounted on the first spring, two sets of vibrating motors fixedly connected to the lower end of the sieve plate, and an anti-clogging component mounted on the sieve plate. The vibrating motors drive the sieve plate to vibrate on the first spring.

[0011] In one optional embodiment, the anti-clogging component includes a third motor fixedly connected to the screen plate, a threaded rod fixedly connected to the output end of the third motor, a slide rod fixedly connected to the screen plate, a mounting plate with one end threaded to the outside of the threaded rod, and a brush mounted on the mounting plate, with the other end of the mounting plate slidably connected to the slide rod.

[0012] In one alternative embodiment, the brush component includes a second spring mounted within a mounting plate, a connecting rod mounted at the lower end of the second spring, and a nylon brush fixedly connected to the lower end of the connecting rod.

[0013] In one optional embodiment, a groove is provided on the mounting plate, and the connecting rod is slidably connected to the mounting plate through the groove. A second spring provides elastic support for the connecting rod, so that the nylon brush abuts against the screen plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model effectively prevents flour from clumping and achieves uniform powdering, improving the quality of noodle production: Through the stirring and heating moisture-proof design of the anti-caking component, the moisture in the flour can be completely removed and the clumps can be broken up.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such process, method, product, or apparatus.

[0021] Please refer to Figures 1-6 A flour-spreading mechanism for noodle production includes a fixed frame 1; it also includes a storage box 2 fixedly connected to the fixed frame 1, a fixed plate 6 fixedly connected to the fixed frame 1, an anti-caking component and a feeding component installed on the storage box 2, and a flour-spreading component installed on the fixed plate 6. The anti-caking component is used to heat the flour, and the feeding component is used to discharge the flour from the storage box 2. The anti-caking assembly includes a first motor 301 fixedly connected to one side of the storage box 2, two sets of stirring racks 302 rotatably connected inside the storage box 2, gears 303 fixedly connected to the two sets of stirring racks 302, and two sets of moisture-proof heating plates 304 fixedly connected to both sides of the storage box 2. The two sets of gears 303 mesh with each other, and the first motor 301 is used to drive the stirring racks 302 to rotate.

[0022] In a preferred embodiment of this utility model, by starting the first motor 301, the first motor 301 drives the stirring rack 302 to rotate, the stirring rack 302 drives the gear 303 to rotate, and the gear 303 drives another set of gears 303 to rotate, thereby driving the two sets of stirring racks 302 to rotate synchronously in opposite directions to stir the flour. The moisture-proof heating plate 304 is activated to heat the surface. Through the dual action of "stirring + heating and moisture-proofing", the moisture in the flour is removed, and the flour is prevented from clumping due to moisture. When it is necessary to sprinkle flour, the feeding component orderly discharges the processed flour from the storage box 2 and transports it to the flour sprinkling component. The flour sprinkling component finally sprinkles the flour evenly on the surface of the noodles, completing the flour sprinkling operation.

[0023] In a preferred embodiment of this utility model, the mixing rack 302 is provided with multiple sets of mixing rods, which are arranged in a star-shaped array on the mixing rack 302. The mixing rods on the two sets of mixing racks 302 are interlaced, thereby improving the uniformity of flour mixing, eliminating mixing dead corners, further enhancing the anti-caking effect of the anti-caking component, and preventing local flour from becoming damp and clumping due to lack of stirring.

[0024] In a preferred embodiment of this utility model, the feeding assembly includes a discharge roller 401 rotatably connected to the inside of the storage box 2, a second motor 403 fixedly connected to one side of the storage box 2, and an intermittent component installed on the discharge roller 401 and the second motor 403. When the second motor 403 starts, it drives the discharge roller 401 to rotate intermittently through the intermittent component. When the discharge roller 401 rotates, the flour on its surface is carried to the lower outlet of the storage box 2 as the roller rotates, completing one feeding cycle. When the discharge roller 401 stops, the feeding is interrupted, thereby realizing the intermittent and quantitative discharge of flour, avoiding excessive flour spreading or clogging of subsequent flour spreading components caused by feeding a large amount of flour at once, and providing a stable flour supply for subsequent uniform flour spreading.

[0025] In a preferred embodiment of this utility model, the intermittent component includes an indexing disk 402 fixedly connected to the discharge roller 401 and a cylindrical indexing cam 404 fixedly connected to the output end of the second motor 403. The second motor 403 drives the cylindrical indexing cam 404 to rotate the indexing disk 402. When the second motor 403 drives the cylindrical indexing cam 404 to rotate at a constant speed, the protruding part of the cam will push the indexing disk 402 to rotate by a preset angle. By controlling the rotation speed of the second motor 403, the frequency of flour feeding can be controlled to adapt to the flour feeding requirements of different noodle production speeds.

[0026] Another embodiment based on intermittent elements: Other existing structures can also be used, such as a Geneva disc, a disc, and a toggle block. By mounting the Geneva disc on the discharge roller 401, with the output end of the second motor 403 facing the storage box 2, and the output end of the second motor 403 fixedly connected to the disc, and the toggle block fixedly connected to the disc, the second motor 403 drives the disc to rotate, the disc drives the toggle block to rotate, the toggle block drives the Geneva disc to rotate intermittently, and the Geneva disc drives the discharge roller 401 to rotate, thus realizing material feeding. The advantage is that the structure is simple, mainly composed of a grooved disc and a toggle disc with a cylindrical pin. The processing requirements are low, and there is no need for complex curved surface contour processing like the cylindrical indexing cam 404. This can greatly reduce the manufacturing cost and processing difficulty of the parts, and is suitable for mass production.

[0027] In a preferred embodiment of this utility model, the powder-spreading assembly includes a first spring 501 fixedly connected to a fixed plate 6, a sieve plate 502 mounted on the first spring 501, two sets of vibrating motors 503 fixedly connected to the lower end of the sieve plate 502, and an anti-clogging component mounted on the sieve plate 502. The vibrating motors 503 drive the sieve plate 502 to vibrate on the first spring 501. When the flour discharged from the feeding assembly falls onto the sieve plate 502, the vibrating motors 503 start, causing the sieve plate 502 to vibrate at high frequency within the elastic range of the first spring 501. The flour is dispersed under the vibration, and the fine flour particles fall evenly through the sieve holes of the sieve plate 502 and are sprinkled onto the noodles being conveyed below. At the same time, the anti-clogging component cleans the sieve holes in real time to prevent flour from clumping and clogging the sieve holes, ensuring that the powder spreading continues.

[0028] In a preferred embodiment of this utility model, the anti-clogging component includes a third motor 504 fixedly connected to the sieve plate 502, a threaded rod 505 fixedly connected to the output end of the third motor 504, a slide rod 507 fixedly connected to the sieve plate 502, a mounting plate 506 with one end threadedly connected to the outside of the threaded rod 505, and a brush mounted on the mounting plate 506. The other end of the mounting plate 506 is slidably connected to the slide rod 507. When the sieve plate 502 is working, the third motor 504 starts, driving the threaded rod 505 to rotate in both directions. The rotational motion of the threaded rod 505 is converted into the reciprocating linear motion of the mounting plate 506 along the slide rod 507 through threaded transmission. The mounting plate 506 drives the brush to move back and forth synchronously. During the movement, the brush brushes the sieve holes of the sieve plate 502, cleaning away the flour clumps stuck in the sieve holes, ensuring that the sieve holes are unobstructed, ensuring the sieving efficiency and powder distribution uniformity of the sieve plate 502, and avoiding powder distribution interruption or insufficient powder distribution in some areas due to sieve hole blockage.

[0029] In a preferred embodiment of this utility model, the brush component includes a second spring 508 installed in the mounting plate 506, a connecting rod 509 installed at the lower end of the second spring 508, and a nylon brush 510 fixedly connected to the lower end of the connecting rod 509. When the second spring 508 is in a naturally extended state, it applies downward elastic pressure to the connecting rod 509, pushing the connecting rod 509 to drive the nylon brush 510 to always be in contact with the surface of the sieve plate 502. This ensures the cleaning effect of the sieve holes, avoids damage to the sieve plate 502 by hard contact of the brush, and adapts to the slight displacement when the sieve plate 502 vibrates, thus improving the cleaning reliability.

[0030] In a preferred embodiment of this utility model, a groove is provided on the mounting plate 506, and the connecting rod 509 is slidably connected to the mounting plate 506 through the groove. The second spring 508 provides elastic support for the connecting rod 509, so that the nylon brush 510 abuts against the sieve plate 502. The groove on the mounting plate 506 and the connecting rod 509 slide in cooperation, allowing the connecting rod 509 to move linearly in the up and down direction along the groove, restricting its left and right and front and back offsets, ensuring that the cleaning trajectory of the nylon brush 510 is consistent with the arrangement direction of the sieve holes of the sieve plate 502, and avoiding the brush offset causing some sieve holes to be missed for cleaning.

[0031] During operation, the first motor 301 is activated, which drives the mixing rack 302 to rotate. The mixing rack 302 then drives the gear 303 to rotate, which in turn drives another set of gears 303 to rotate. This causes both sets of mixing racks 302 to rotate synchronously in opposite directions, thus mixing the flour. Simultaneously, the moisture-proof heating element 304 is activated to heat the flour. This process combines mixing with heating and moisture prevention. The system has a dual function: removing moisture from the flour and preventing it from clumping due to dampness. When the second motor 403 drives the cylindrical indexing cam 404 to rotate at a constant speed, the cam's protruding part pushes the indexing plate 402 to rotate by a preset angle. The indexing plate 402 drives the discharge roller 401 to rotate intermittently. When the discharge roller 401 rotates, the flour on its surface is carried to the outlet below the storage tank 2, completing one feeding cycle. When the discharge roller 401 stops, the feeding is interrupted, thus achieving intermittent and quantitative flour discharge. This avoids excessive flour spreading or clogging of subsequent flour spreading components due to large-scale flour feeding at once, providing a stable flour supply for subsequent uniform flour spreading. The vibration motor 503 drives the sieve plate 502 to vibrate on the first spring 501. When the flour discharged from the feeding component falls onto the sieve plate 502, the vibration motor 503 starts. The sieve plate 502 vibrates at high frequency within the elastic range of the first spring 501. Under the action of vibration, the flour is broken up, and the fine flour particles fall evenly through the sieve holes of the sieve plate 502 and are sprinkled on the noodles conveyed below. The third motor 504 starts and drives the threaded rod 505 to rotate forward or reverse. The rotational motion of the threaded rod 505 is converted into the reciprocating linear motion of the mounting plate 506 along the slide rod 507 through the threaded transmission. The mounting plate 506 drives the nylon brush 510 to move back and forth synchronously. When the second spring 508 is in a naturally extended state during the movement of the nylon brush 510, it will apply downward elastic pressure to the connecting rod 509, pushing the connecting rod 509 to drive the nylon brush 510 to always be in contact with the surface of the sieve plate 502, brushing the sieve holes of the sieve plate 502, cleaning the flour clumps stuck in the sieve holes, and ensuring that the sieve holes are unobstructed.
