Description

Technical Field

[0001] This application relates to the technical field of modified atmosphere packaging, and in particular to a dual-material packaging equipment and method for small packages of Chinese medicinal materials and finished grains. Background Technology

[0002] Modified atmosphere packaging (MAP) is a preservative that absorbs oxygen and releases carbon dioxide. Developed specifically for modified atmosphere storage, it is primarily used for storing dry goods such as medicinal herbs, tobacco, nuts, tea, grains, and finished grains. MAP mainly consists of reduced iron powder and a catalyst. The process involves mixing the catalyst with the reduced iron powder, then packaging the mixture in breathable bags to absorb oxygen.

[0003] The common packaging method involves mixing the catalyst and reduced iron powder and pouring the mixture into a large feed hopper. Since modified atmosphere packaging (MAP) is typically packaged in small packets—for example, in packaging bags for traditional Chinese medicine or 5kg packages of finished rice—the thoroughly mixed MAP needs to be gradually discharged in small amounts to achieve this small-packaging. However, after the catalyst and reduced iron powder are mixed, the MAP in the feed hopper begins to rapidly absorb oxygen. This results in the MAP being exposed to air for a longer period, leading to a loss of oxygen absorption capacity, which requires improvement. Summary of the Invention

[0004] To reduce the loss of oxygen absorption capacity of modified atmosphere packaging agents during the packaging process, this application provides a dual-material packaging device for small packages of modified atmosphere packaging agents for traditional Chinese medicine and finished grain.

[0005] On the one hand, the dual-material packaging equipment for small packages of Chinese medicinal materials and finished grains provided in this application adopts the following technical solution:

[0006] A dual-material packaging device for small packages of Chinese medicinal herbs and finished grains with modified atmosphere packaging includes a support frame, a feeding mechanism, a mixing mechanism, and a packaging mechanism. The feeding mechanism includes a first feeding hopper for placing additives, a first discharging component for receiving the material from the first feeding hopper and discharging it quantitatively, a second feeding hopper for placing iron powder, and a second discharging component for receiving the material from the second feeding hopper and discharging it quantitatively. The mixing mechanism includes a rotating component and a mixing cup disposed on the rotating component. The rotating component drives the mixing cup to rotate and passes successively below the first discharging component and the second discharging component. A discharge port and a lower sealing component for opening and closing the discharge port are provided below the mixing cup. The packaging mechanism is located below the discharge port and packages the mixture falling from the mixing cup.

[0007] By adopting the above technical solution, the overall oxygen absorption capacity of the additive is basically not lost before it is mixed with the iron powder. The additive and iron powder are quantitatively fed through the first and second discharge components, respectively. They are then collected by a mixing cup and discharged through the outlet. Before the discharge, a lower sealing component closes the outlet and prevents the material from falling. Since the mixing cup passes under the first and second discharge components first, most of the additive is located below the iron powder. During the discharge process, because the iron powder is heavier than the additive, it falls faster due to air resistance, thus achieving mixing during the fall. The mixed material is then directly packaged by the packaging mechanism. This packaging equipment, compared to the original method of first mixing all materials into a modified atmosphere and then gradually packaging in small quantities, effectively reduces oxygen loss. Meanwhile, taking advantage of the fact that iron powder is heavier than additives and that modified atmosphere packaging agents are typically packaged in small quantities, a direct mixing method was adopted, which met the mixing requirements and ensured the performance of the modified atmosphere packaging agent.

[0008] Optionally, the rotating component includes a support shaft that is relatively fixed to the support frame and a rotating disk that is rotatably connected to the support shaft. Multiple mixing cups are provided, and the multiple mixing cups are distributed in a circumferential array on the rotating disk.

[0009] By adopting the above technical solution, multiple mixing cups are distributed in a circular array along the rotating disk. During the rotation of the rotating disk, the mixing cups can be rotated to the same specific position, which facilitates the fixed-point discharge of the first and second discharge components and improves the working efficiency.

[0010] Optionally, the lower sealing assembly includes a sealing plate hinged to the rotating disk, an elastic element disposed on the rotating disk and driving the sealing plate to block the discharge port, and a pushing element for driving the sealing plate to rotate and move away from the discharge port.

[0011] By adopting the above technical solution, when the pushing component does not apply force to the sealing plate, the sealing plate, under the force of the elastic component, blocks the discharge port and prevents the material from falling. When material discharge is required, the pushing component abuts against the sealing plate to rotate the sealing plate, thereby achieving material discharge.

[0012] Optionally, the pusher is relatively fixed on the support shaft, and a rotating block that abuts against the sealing plate is rotatably connected to the pusher.

[0013] By adopting the above technical solution, and by adjusting the position of the pusher and the sealing plate, it is easy to adjust the opening or closing of the discharge port at a fixed position, which facilitates the automated design of the product.

[0014] Optionally, both the first discharge assembly and the second discharge assembly include a fixed-material rotating drum for receiving iron powder or additives. The fixed-material rotating drum is rotatable, and multiple filling channels are opened on the inner bottom of the fixed-material rotating drum. The lower end of the fixed-material rotating drum is provided with an upper sealing assembly for opening or closing the material discharge of the filling channels. A scraper plate fixed to the support frame is provided inside the fixed-material rotating drum, and the scraper plate is used to scrape away the material outside the filling channels.

[0015] By adopting the above technical solution, the fixed material rotating drum continuously fills the filling channel by rotating, and the scraper removes the excess material, thereby achieving quantitative filling.

[0016] Optionally, the scraper is provided with an auxiliary material discharge rod, and during the rotation of the fixed material rotating drum, the auxiliary material discharge rod abuts against the material in the packing channel.

[0017] By adopting the above technical solution, adjustments can be made to ensure that when the seasoning channel is aligned with the mixing cup, the upper sealing component does not block the filling channel, and the auxiliary discharge rod resists the material in the filling channel, thus facilitating material discharge.

[0018] Optionally, the auxiliary material discharge rod includes a metal elastic rod connected to the scraper and a plastic rod fixedly connected to the metal elastic rod; one end of the plastic rod abuts against the inner bottom of the fixed material rotating drum and is used to abut against the material in the filler channel.

[0019] By adopting the above technical solution, both the plastic rod and the metal elastic rod can deform, and the plastic rod has low hardness, so it is not easy to cause wear to the inner bottom of the fixed material rotating drum.

[0020] Optionally, the packaging mechanism includes a falling channel and a packaging component; the upper opening of the falling channel is located below the discharge port, and the lower opening of the falling channel is connected to the packaging component, which seals and packages the material passing through the falling channel; a funnel with a larger opening at the top and a smaller opening at the bottom is provided inside the falling channel; there is a gap between the upper end of the funnel and the inner wall of the falling channel, and the outer wall of the funnel and the inner wall of the falling channel are fixedly connected by a connecting rod.

[0021] By adopting the above technical solution, during the falling process of the additives and iron powder, when some of the additives and iron powder pass through the funnel, the middle portion of the material will fall first, which is conducive to the thorough mixing of the additives and iron powder. In addition, there is a gap between the upper end of the funnel and the inner wall of the falling channel. This gap allows a small portion of the material to pass through. Some material is altered as it passes through the funnel, while some material is mixed only due to its own weight difference and the different falling speeds. These two different mixing methods have a wider range of applications.

[0022] Optionally, it also includes an identification mechanism for identifying whether the packaging bag is properly packaged; the identification mechanism includes a camera for capturing and outputting the area and position of the shadow within the packaging bag.

[0023] By adopting the above technical solution, this method of judging whether the packaging is in place by the proportion of shadows is more efficient and faster and more accurate than the original method of weighing to check whether the packaging quantity is in place and the original method of manually judging whether the heat seal is stuck.

[0024] On the other hand, this application also provides a dual-material packaging method for traditional Chinese medicine materials and small-packaged modified atmosphere packaging of finished grains, including the following steps:

[0025] The additives and iron powder are fed separately. The additives are placed in the first feeding bucket and fed in a quantitative manner, while the iron powder is placed in the second feeding bucket and fed in a quantitative manner.

[0026] The additives and iron powder are mixed. The quantitatively fed additives and iron powder are collected by the mixing mechanism. After collection, they are fed back to mix them.

[0027] The unloading and packaging process involves collecting and packaging the additives and iron powder that have been unloaded.

[0028] By adopting the above technical solution and using a dual-material feeding method, compared to the original method of first mixing all materials into a modified atmosphere and then gradually packaging small quantities, it can effectively avoid the problems of material sticking to the hopper, uneven feeding, material jamming, and loss of oxygen consumption capacity before packaging caused by full mixing. It also effectively reduces the difficulty of factory equipment maintenance and shortens equipment cleaning time. Furthermore, due to the small packaging, the mixing of the additive and iron powder can be achieved directly during the feeding process, taking advantage of the fact that iron powder is heavier than the additive.

[0029] In summary, this application significantly reduces the loss of oxygen absorption capacity by separating the modified atmosphere into iron powder and additives, which are only mixed just before packaging. The mixture falls and falls simultaneously into the packaging bag, and the next step is immediate sealing. Attached Figure Description

[0037] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0038] Example 1:

[0039] This application discloses a dual-material packaging device for small packages of traditional Chinese medicinal materials and finished grain products, referring to... Figure 1 The system includes a support frame 1, a feeding mechanism 2, a mixing mechanism 3, a packaging mechanism 4, and an identification mechanism 5. The feeding mechanism 2 is used to quantitatively dispense the additives and iron powder. The mixing mechanism 3 is located below the feeding mechanism 2 and receives the additives and iron powder from it. The packaging mechanism 4 is located below the mixing mechanism 3 and packages the mixture falling from the mixing mechanism 3 into modified atmosphere packaging bags. The identification mechanism 5 is used to identify whether the packaging bags are properly packaged.

[0040] Reference Figure 1 The feeding mechanism 2 includes a first feeding hopper 6 for holding additives, a first discharging component 7 for receiving the material from the first feeding hopper 6 and discharging it quantitatively, a second feeding hopper 8 for holding iron powder, and a second discharging component 9 for receiving the material from the second feeding hopper 8 and discharging it quantitatively. It should be noted that in this embodiment, the first feeding hopper 6 and the second feeding hopper 8 are the same, and the first discharging component 7 and the second discharging component 9 are the same. The following further disclosure uses the first feeding hopper 6 and the first discharging component 7 as examples.

[0041] Reference Figure 2 The first feeding hopper 6 has a large opening at the top for workers to pour in materials, and a small opening at the bottom for discharging materials. The first discharging assembly 7 includes a fixed material rotating hopper 10 located below the first feeding hopper 6 for receiving additives. The fixed material rotating hopper 10 is rotatably connected relative to the support frame 1, and can be driven to rotate by a motor.

[0042] Reference Figure 2 The fixed material rotating drum 10 is equipped with a scraper 11 fixed to the support frame 1. The scraper 11 is arc-shaped and divides the fixed material rotating drum 10 into a material accumulation area 12 and a material depletion area 13. The lower opening of the first feeding drum 6 is located in the material accumulation area 12, and the material in the first feeding drum 6 is conveyed to the material accumulation area 12 under its own gravity.

[0043] Reference Figure 2 , Figure 3 The inner bottom of the rotating material container 10 has multiple filling channels 14, which are arranged in a circular array along the circumference of the rotating material container 10. The lower end of the rotating material container 10 is provided with an upper sealing assembly 15 for opening or closing the material discharge of the filling channels 14, and the upper sealing assembly 15 is arranged in a one-to-one correspondence with the filling channels 14.

[0044] Reference Figure 2 , Figure 3 The upper sealing assembly 15 includes a sealing plate 16, an elastic element 17, and a pushing element 18. An upper shaft 19 is provided at the bottom of the material rotating drum 10, and the sealing plate 16 is rotatably connected to the bottom of the material rotating drum 10 via the upper shaft 19. The elastic element 17 is a torsion spring, which is sleeved on the upper shaft 19, and its two ends are respectively connected to the sealing plate 16 and the upper shaft 19. Under its own elastic force, the torsion spring drives the sealing plate 16 to rotate below the corresponding filling groove 14 and blocks the filling groove 14, thereby closing the material discharge. The pushing element 18 is fixedly connected to the support frame 1, and a rotating block 20 that abuts against the sealing plate 16 is rotatably connected to the pushing element 18. The sealing plate 16 includes an integrally formed blocking plate 42. When the fixed material rotating drum 10 rotates, the blocking plate 42 on the blocking plate 16 abuts against the rotating block 20, thereby causing the blocking plate 16 to rotate relative to the fixed material rotating drum 10, causing the blocking plate 16 to be misaligned with the lower opening of the filling channel 14, so that the material in the filling channel 14 can fall. When the blocking plate 16 no longer abuts against the pushing member 18, under the action of the torsion spring, the blocking plate 16 seals the lower opening of the filling channel 14 again.

[0045] During the rotation of the fixed material rotating drum 10, when the filling channel 14 rotates to the stacking area 12, the material will fall into the filling channel 14. When the filling channel 14 passes the position of the scraper 11, the excess material above the filling channel 14 is blocked and scraped off by the scraper 11. When the filling channel rotates to a specific position, the sealing plate 16 in the upper sealing assembly 15 rotates and opens, thereby realizing the quantitative dropping of the material.

[0046] Reference Figure 2 The scraper plate 11 is equipped with an auxiliary discharge rod 21 located in the low-material zone 13. The auxiliary discharge rod 21 includes a metal elastic rod 22 connected to the scraper plate 11 and a plastic rod 23 fixedly connected to the metal elastic rod 22. The lower end of the plastic rod 23 can abut against the inner bottom of the fixed material rotating drum 10 and is used to abut against the material in the filling channel 14. During the rotation of the fixed material rotating drum 10, the plastic rod 23 abuts against the material in the filling channel 14, which facilitates the discharge of material. In this embodiment, a cable tie is used to fix the plastic rod 23 to the metal elastic element 17, which facilitates the replacement of the plastic rod 23. The plastic rod 23 is used because plastic has low hardness and is less likely to cause wear to the inner bottom of the fixed material rotating drum 10.

[0047] Reference Figure 1 , Figure 4 The mixing mechanism 3 includes a rotating component 24 and mixing cups 25 disposed on the rotating component 24. The rotating component 24 includes a support shaft 26 relatively fixed to the support frame 1 and a rotating disk 27 rotatably connected to the support shaft 26. The rotating disk 27 can be rotated by connecting a motor. Multiple mixing cups 25 are provided, and the multiple mixing cups 25 are distributed in a circumferential array on the rotating disk 27. During the rotation of the rotating disk 27, the mixing cups 25 can be rotated to the same specific position, which facilitates the fixed-point discharge of the first discharge component 7 and the second discharge component 9, thereby improving the working efficiency.

[0048] It should be mentioned that during the rotation of the same mixing cup 25, it first passes under the first discharge component 7 and then under the second discharge component 9. That is, the same mixing cup 25 receives the additives first and then the iron powder.

[0049] Reference Figure 4 Below the mixing cup 25 is a discharge port 28 embedded in the rotating disk 27. Below the rotating disk 27 is a lower sealing assembly 29 that corresponds one-to-one with the discharge port 28 and is used to open and close the discharge port 28.

[0050] Reference Figure 4The lower sealing assembly 29 is identical to the upper sealing assembly 15, both including a sealing plate 16, an elastic element 17, and a pushing element 18. A lower shaft 30 is provided at the lower end of the rotating disk 27. The sealing plate 16 in the lower sealing assembly 29 is rotatably connected to the rotating disk 27 via the lower shaft 30. The elastic element 17 is a torsion spring, which is sleeved on the lower shaft 30, with its two ends connected to the sealing plate 16 and the lower shaft 30 respectively. Under its own elastic force, the torsion spring drives the sealing plate 16 to rotate below the corresponding discharge port 28 and blocks the discharge port 28, thereby closing the material discharge. The pushing element 18 in the lower sealing assembly 29 is fixedly mounted on the support shaft 26. Similarly, by adjusting the position of the pushing element 18, during the rotation of the rotating disk 27, the sealing plate 16 in the corresponding lower sealing assembly 29 can be made to contact and rotate with the pushing element 18 when it rotates to a specific position, thereby allowing the material in the mixing cup 25 to discharge.

[0051] Reference Figure 1 The packaging mechanism 4 includes a packaging component 31 and a bag conveying component 32. The bag conveying component 32 is used to convey unsealed bags. The packaging mechanism 4 is located below the mixing mechanism 3 and is used to receive the mixture in the mixing cup 25. Specifically, the packaging component 31 bends the unsealed bags and then heat-seals the bent bags. In this process, the falling mixture is heat-sealed into continuous small bags.

[0052] Reference Figure 1 The packaging assembly 31 includes a curved guide plate 40 fixed to the support frame 1 and a power component 41. The packaging bags output from the packaging bag conveying assembly 32 are continuously transported downwards under the force of the power component 41, and the packaging bags gradually bend under the guidance of the curved guide plate 40.

[0053] Reference Figure 1 The packaging component 31 also includes a heat-sealing clamp 33 for heat-sealing the packaging bag. The heat-sealing clamp 33 is L-shaped. Each time the heat-sealing clamp 33 clamps and heat-seales, it can form a complete small packaging bag. At the same time, it heat-seals the packaging bag connected to the top of the small packaging bag so that three sides are heat-sealed and the top is open, so as to better receive the mixture falling from the mixing cup 25. In this embodiment, there is a distance of 20 cm to 30 cm between the heat-sealing clamp 33 and the lower end of the mixing cup 25. Since the iron powder is heavier than the additive, under the action of air resistance and other forces, the mixture with the additive at the bottom and the iron powder at the top is mixed by the difference in falling speed during the falling process.

[0054] Reference Figure 1The identification device 5 includes a camera 34 located on one side of the packaging bag and a whiteboard 35 located on the other side of the packaging bag. The camera 34 is used to capture and output the area and position of the shadow within the packaging bag. Since it is a small bag packaging, the shadow ratio can be used to roughly determine whether the modified atmosphere packaging is in place. For example, whether the amount of mixed material inside the bag is within the appropriate range, and whether there is mixed material trapped in the four seals of the bag. This method of determining whether the packaging is in place using the shadow ratio is more efficient and faster than the original method of weighing to check the quantity of packaging.

[0055] This application also provides a dual-material packaging method for traditional Chinese medicine materials and small-packaged modified atmosphere packaging of finished grains, including the following steps:

[0056] S1. Additives and iron powder are fed separately. Additives are placed in the first feeding bucket 6 and fed in a quantitative manner, while iron powder is placed in the second feeding bucket 8 and fed in a quantitative manner.

[0057] S2. The additives and iron powder are mixed. The additives and iron powder are collected after being quantitatively fed through the mixing mechanism 3, and then fed back to mix them.

[0058] S3. Unloading and Packaging. The unloaded additives and iron powder are collected and packaged.

[0059] The dual-material feeding method, compared to the original method of first mixing all materials into a modified atmosphere mixture and then gradually packaging in small quantities, effectively avoids many problems caused by full mixing, such as material sticking to the hopper during packaging, uneven feeding, material jamming, loss of oxygen consumption capacity before packaging, reduced difficulty in factory equipment maintenance, and shorter equipment cleaning time. Furthermore, due to the small packaging, the additives and iron powder are mixed directly during the feeding process, taking advantage of the fact that iron powder is heavier than the additives.

[0060] Furthermore, the modified atmosphere packaging (MAP) in this application comprises 56% reduced iron powder; the additives include: 8% activated carbon, 2% salt, 4% vermiculite, 12% silica, and 18% water. The reduced iron powder is 120 mesh, larger than the traditional 80-100 mesh, allowing for better dispersion during the mixing of the two materials. The activated carbon has an iodine value greater than 1000. Because the two materials are mixed (not completely uniformly), activated carbon with a high adsorption value is needed to better enrich oxygen, which is beneficial for the reaction.

[0061] Example 2:

[0062] This embodiment discloses a dual-material packaging device for small packages of Chinese medicinal materials and finished grains with modified atmosphere packaging. Unlike Embodiment 1, it refers to… Figure 5The packaging mechanism 4 also includes a drop channel 36 located between the packaging component 31 and the mixing cup 25. The upper opening of the drop channel 36 is located below the discharge port 28, and the lower opening of the drop channel 36 is connected to the packaging component 31. Specifically, the lower end of the drop channel 36 is inserted into the curved packaging bag that has not yet been packaged.

[0063] Reference Figure 5 , Figure 6 The falling channel 36 is equipped with a funnel 37, which has a wider opening at the top and a narrower opening at the bottom. A gap 39 exists between the outer wall of the upper end of the funnel 37 and the inner wall of the falling channel 36. The outer wall of the funnel 37 and the inner wall of the falling channel 36 are fixedly connected by a connecting rod 38. During the falling process, when some of the additives and iron powder pass through the funnel 37, the material in the middle will fall first, which is beneficial for the thorough mixing of the additives and iron powder. Furthermore, the gap 39 between the outer wall of the funnel 37 and the inner wall of the falling channel 36 allows a small portion of the material to pass through. Some material is altered as it passes through the funnel 37, while some material is mixed only due to its own weight difference and the different falling speeds. This two different mixing methods have a wider range of applications.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.

After collection, the additives are fed back to mix them. The unloading and packaging process involves collecting and packaging the additives and iron powder that have been unloaded. The same mixing cup first receives the additives and then the iron powder. Taking advantage of the fact that the iron powder is heavier than the additives, the additives and iron powder are mixed directly during the feeding process.
