[0002] Oxygen absorbers, also known as oxygen removers or oxygen absorbers, are additives that absorb oxygen and slow down the oxidation of food. They are new products being used in food preservation. They are a group of chemical mixtures that easily react with free or dissolved oxygen. When packaged in a sealed paper bag with a certain degree of air permeability and strength, and sealed together with the food in a food bag, they can remove the oxygen remaining in the air in the bag, preventing the food from discoloring, spoiling, and rancidifying due to oxidation.

[0003] Because deoxidizer powder reacts readily with oxygen in the air, causing it to clump and agglomerate, the deoxidizer in existing feeding devices is difficult to pass through the feeding cup orifice, severely affecting packaging efficiency. In addition, existing feeding devices feed through a single feeding cup orifice during packaging, which is very inefficient. Summary of the Invention

[0027] To explain in detail the technical content, structural features, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0028] like Figures 1 to 9As shown, this utility model provides a multi-row feeding device 10, including a hopper 1, a cover plate 2, a feeding plate 41, and multiple feeding units corresponding to the hopper 1. The hopper 1 has an open structure at both ends. The upper part of the hopper 1 is covered by the cover plate 2, and the lower part of the hopper 1 is installed on the feeding plate 41 to form a closed cavity between the cover plate 2, the hopper 1, and the feeding plate 41. The closed cavity is filled with inert gas during operation. Each feeding unit includes a drive shaft 34, a scraper 35, a feeding groove 411, a feeding cup hole 412, and a gate plate 427. The feeding groove 411 is provided on the feeding plate 41, and the feeding cup hole 412... A material gate plate 427 is located on the bottom of the material feeding groove 411, with the material cup hole 412 penetrating through the material feeding plate 41. A scraper plate 35 is located at the lower end of the drive shaft 34, which passes through the cover plate 2 and extends into the material feeding groove 411 so that the scraper plate 35 is positioned within the groove. The upper end of the drive shaft 34 is also connected to a drive assembly, which is installed above the cover plate 2 to drive the drive shaft 34 to rotate the scraper plate 35 to scrape material into the material cup hole 412 when the material gate plate 427 closes the bottom of the material cup hole 412. Specifically, the inert gas can be nitrogen. When the hopper 1 is filled with nitrogen, the air in the hopper 1 can be discharged, preventing the deoxidizer and other materials from reacting with oxygen, which could lead to clumping and agglomeration, thus ensuring smoother material feeding. In addition, the drive shaft 34 is rotatably connected to the cover plate 2. The material gate plate 427 has a first state of blocking the lower part of the material cup hole 412 and a second state of not blocking the lower part of the material cup hole 412. In the first state, the material gate plate 427 forms a measuring cup with the material cup hole 412. The scraper plate 35 rotates relative to the material groove 411 under the drive of the drive assembly to scrape material into the measuring cup. The size of the scraper plate 35 is larger than the size of the material cup hole 412 so that the upper part of the material cup hole 412 is blocked after the measuring cup is filled with material. The hopper 1 contains materials such as deoxidizers. The multi-row feeding unit can be, for example, five-row feeding units. The five-row feeding units can be arranged sequentially along the length of the cover plate 2. The drive assembly drives the transmission shaft 34 to rotate and scrapes the deoxidizer powder and other materials in the hopper 1 into the measuring cup until the measuring cup is full. After the measuring cup is full, the material gate plate 427 changes from the first state to the second state. At this time, the scraper plate 35 blocks the upper part of the feeding cup hole 412, so that the material is discharged from the lower part of the feeding cup hole 412 for packaging deoxidizers, etc. In addition, the feeding plate 41 is supported by support feet 43 to give the feeding plate 41 a certain height for easy feeding.

[0029] This utility model embodiment forms a closed cavity between the cover plate 2, the hopper 1, and the discharge plate 41, and the closed cavity is filled with inert gas to prevent the deoxidizing agent and other materials from reacting with oxygen and causing clumping and agglomeration, thus making the discharge smoother. In addition, this utility model has a very high discharge efficiency and a very compact structure by setting multiple rows of discharge units.

[0030] In this embodiment of the utility model, such as Figures 1 to 2 as well as Figure 7 , Figure 9 As shown, a connecting plate 30 is also supported above the cover plate 2. The driving assembly includes a first drive motor 31, which is mounted on the connecting plate 30. The upper end of each drive shaft 34 is connected to a first gear 32. A driven gear 33 meshes between adjacent first gears 32. The driven gear 33 is connected to the output end of the first drive motor 31 to make the multiple drive shafts 34 in the multiple rows of feeding units rotate synchronously. Specifically, the connecting plate 30 is supported on the cover plate 2 by support columns 301. For example, it can be supported by six evenly arranged support columns 301. Multiple first gears 32 are arranged sequentially at intervals along the length direction of the connecting plate 30. Multiple driven gears 33 are arranged on the rear side of the first gears 32 and mesh with adjacent first gears 32. The output end of the first drive motor 31 faces downward and is connected to a driven gear 33 and drives the driven gear 33 to rotate so as to drive the multiple first gears 32 to rotate synchronously.

[0031] In this embodiment of the utility model, such as Figures 1 to 2 as well as Figure 7 , Figure 9 As shown, a plurality of upwardly extending connecting posts 413 are fixedly connected to the feeding plate 41. The connecting posts 413 are located at both ends of the feeding plate 41 along its length. The connecting posts 413 pass through the cover plate 2 and are connected to the cover plate 2 via connectors. Specifically, the connecting posts 413 can be two, respectively located at the middle of the two ends of the cover plate 2 along its length. The connector can be a detachable open-type fixing ring 415. The open-type fixing ring 415 is sleeved on the connecting post 413 and abuts against the cover plate 2, thereby locking the connecting post 413 to the cover plate 2 and clamping the hopper 1 between the cover plate 2 and the feeding plate 41, preventing the hopper 1 from shifting. When it is necessary to clean the hopper 1, the open-type fixing ring 415 can be loosened, thereby removing the cover plate 2, the first drive motor 31, the first gear 32, the driven gear 33, and the transmission shaft 34 from the hopper 1 as a whole, realizing the detachable connection between the cover plate 2 and the hopper 1, which is convenient for cleaning.

[0032] In this embodiment of the utility model, such as Figures 1 to 2 as well as Figures 5 to 9 As shown, a plurality of upwardly extending guide posts 414 are fixedly connected to the feed plate 41. The guide posts 414 are located at both ends of the feed plate 41 along its length. The guide posts 414 pass through the cover plate 2 and are slidably connected to the cover plate 2. Specifically, a guide sleeve 21 is fixedly attached to the cover plate 2 corresponding to the guide posts 414. The guide posts 414 pass through the guide sleeve 21 to be slidably connected to the cover plate 2. For example, there can be four guide posts 414, which are located at the four corners of the cover plate 2 and the feed plate 41, respectively. The installation of the cover plate 2 is facilitated by the setting of the guide posts 414.

[0033] In this embodiment of the utility model, such as Figures 5 to 9 As shown, a first engaging groove 23 is provided on the side of the cover plate 2 facing the feeding plate 41, and the upper part of the hopper 1 is embedded in the first engaging groove 23; a second engaging groove 416 is provided on the side of the feeding plate 41 facing the cover plate 2, and the lower part of the hopper 1 is embedded in the second engaging groove 416. Specifically, the first engaging groove 23 and the second engaging groove 416 further limit the position of the hopper 1, preventing the hopper 1 from shifting and causing material leakage, and ensuring the airtightness of the hopper 1.

[0034] In this embodiment of the utility model, such as Figures 5 to 8 As shown, the lower end of the drive shaft 34 is located at the center of the feeding groove 411, and the feeding cup hole 412 is located on one side of the lower end of the drive shaft 34. Specifically, the feeding cup hole 412 is located on one side of the lower part of the drive shaft 34 to ensure that the scraper plate 35 can scrape material into the feeding cup hole 412 during rotation, which is a clever design.

[0035] In this embodiment of the utility model, such as Figures 6 to 8 As shown, the outer side of the scraper 35 includes an arc-shaped surface 351, a first connecting surface 352, and a second connecting surface 353. The arc-shaped surface 351 is provided corresponding to the inner wall of the feeding groove 411. One end of the arc-shaped surface 351 is connected to the first connecting surface 352, and the other end of the arc-shaped surface 351 is connected to the second connecting surface 353. The first connecting surface 352 has a planar structure, and the second connecting surface 353 has an inwardly recessed surface corresponding to the feeding cup hole 412. Specifically, the arc-shaped surface 351 is set to correspond to the inner wall of the feeding groove 411. The arc-shaped surface 351 is a circular arc surface. The central angle of the cross section of the circular arc surface 351 in the horizontal direction is greater than or equal to 45 degrees and less than or equal to 90 degrees. This ensures that the scraper 35 does not interfere with the inner wall of the feeding groove 411 during rotation, while ensuring the structural strength of the scraper 35 and not occupying too much space in the feeding groove 411, thus avoiding affecting the feeding. In addition, by providing a concave surface on the second connecting surface 353, which corresponds to the design of the feeding cup hole 412, more material can be scraped into the feeding cup hole 412.

[0036] In this embodiment of the utility model, such as Figures 5 to 8As shown, a scraper strip 36 is also connected to the lower part of the drive shaft 34. The scraper strip 36 is disposed on the scraper plate 35, and at least a portion of the projection of the scraper strip 36 in the vertical direction is located outside the projection of the material discharge groove 411 in the vertical direction. In this embodiment of the present invention, the scraper plate 35 is provided with an embedding groove 354, and the scraper strip 36 is provided with an embedding protrusion 361 corresponding to the embedding groove 354. The embedding protrusion 361 is embedded in the embedding groove 354 to ensure the strength of the scraper strip 36. At least a portion of the projection of the scraper strip 36 in the vertical direction is located outside the projection of the material discharge groove 411 in the vertical direction, so that the scraper strip 36 can scrape the material outside the material discharge groove 411 into the material discharge groove 411 and can loosen the material to prevent the material from clumping.

[0037] In this embodiment of the utility model, such as Figures 1 to 3 as well as Figures 7 to 9 As shown, the bottom surface of the feeding plate 41 is also provided with a second drive motor 421, a sliding guide rail 423, a sliding block 424, a connecting strip 425, and multiple adapter plates 426. The connecting strip 425 is connected to the sliding block 424. The second drive motor 421 is connected to one end of the connecting strip 425 to drive the connecting strip 425 to slide along the sliding guide rail 423. Multiple adapter plates 426 are evenly spaced on the connecting strip 425. Each adapter plate 426 is also rotatably connected to one end of the material gate plate 427. The middle part of the material gate plate 427 is rotatably connected to the feeding plate 41. The other end of the material gate plate 427 is used to open or close the lower part of the feeding cup hole 412. Specifically, the middle part of the material gate plate 427 is rotatably connected to the material feed plate 41 via a rotating shaft 428. The second drive motor 421 is connected to one end of the connecting strip plate 425 via a connecting rod 422 to drive the connecting strip plate 425 to slide along the sliding guide rail 423. The connecting strip plate 425 drives the adapter plate 426 to move, thereby driving the material gate plate 427 to rotate along the rotating shaft 428 so that the material gate plate 427 opens and closes the material feed cup hole 412, thereby switching between the first state and the second state. The design is very ingenious.

[0038] In this embodiment of the utility model, such as Figure 1 , Figure 4 as well as Figure 7 As shown, the cover plate 2 is also provided with a feed inlet 22, and the hopper 1 is provided with an inclined feeding surface 11 corresponding to the feed inlet 22 so that the hopper 1 forms a guiding structure that is wider at the top and narrower at the bottom. Specifically, the feed inlet 22 can be used to feed materials into the hopper 1. The feed inlet 22 is located on the front side of the cover plate 2, and the connecting plate 30 is installed on the rear side of the cover plate 2. The structure is compact. At the same time, the inclined feeding surface 11 can smoothly guide the materials to the feeding groove 411. The structural design is ingenious. In addition, the feed inlet 22 is sealed by a sealing plate when the multi-row feeding device 10 is working.
