Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a feeding device for industrial food processing. Background Technology

[0002] With the rapid development of the food industry, large-scale, continuous, and automated production has become the mainstream trend. In many food production processes such as baking, puffing, condiments, dairy products, confectionery, and meat processing, the transportation and feeding of raw materials are key links connecting the preceding and following processes. Their efficiency, hygiene, and reliability directly affect the quality, safety, and production cost of the final product.

[0003] The prior art CN222159091U discloses a food processing feeding device. This device controls a pushing block to slide downwards and scrape the inner wall of the conveying pipe, so that the raw materials inside the conveying pipe can be squeezed downwards by the pushing block and discharged. This reduces the possibility of raw materials blocking the internal space of the conveying pipe and allows the raw materials adhering to the inside of the conveying pipe to be cleaned in time, preventing the residue from remaining on the inner wall of the conveying pipe. This prevents the residual raw materials inside the conveying pipe from deteriorating, ensuring that the subsequently discharged raw materials are not affected by the deteriorated raw materials and avoiding food safety hazards. However, in the industrial food processing sector, high-value-added powdered ingredients are often added as processing raw materials. These powdered ingredients are prone to a "bridging" effect during the feeding process, which affects the feeding operation. The way to break the "bridging" effect is by stirring. Whether it is high-speed stirring or slow stirring, the long-term friction between the stirring blade and the raw material will generate heat. For temperature-sensitive ingredients (such as certain vitamins, probiotics, and protein powder), this continuous heat accumulation is enough to reduce their activity or cause denaturation. If the raw material is a premixed mixture, stirring will cause secondary separation due to differences in particle density and size, which will destroy the uniformity of the formula. Summary of the Invention

[0004] The purpose of this invention is to provide a feeding device for industrial food processing to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding device for industrial food processing, comprising an outer cylinder and an inner cylinder, wherein a movable component is provided inside the outer cylinder, and the inner cylinder is slidably connected to the inner side of the outer cylinder through the movable component, and the top of the inner cylinder is closed. The bottom of the inner cylinder is provided with a material delivery block, the top of the material delivery block is provided with a concave inclined structure, and the top of the material delivery block is provided with an elastic sheet. The top layer of the elastic sheet is made of rigid material, and the rest is made of elastic material. One side of the top layer slides against the inner wall of the inner cylinder, and one end of the bottom layer slides against the top of the inner cylinder. The elastic sheet is arranged in a ring shape, and the top of the elastic sheet is provided with a connecting component for the elastic sheet to deform. A feed pipe is fixedly connected through the top of the outer cylinder, a rotary switch is fixedly connected through the top of the inner cylinder, the opening of the rotary switch corresponds to the feed pipe, and a discharge pipe is fixedly connected through one side of the outer cylinder.

[0006] Preferably, the moving component includes a motor and a threaded rod. A fixed cover is fixedly connected to the top of the outer cylinder, and the motor is fixedly installed inside the fixed cover. The top end of the threaded rod is fixedly connected to the bottom of the motor drive end. A fixed screw block is fixedly connected to the outer side of the inner cylinder. The fixed screw block is threadedly connected to the surface of the threaded rod. A moving groove is opened on the inner side of the outer cylinder. The threaded rod is rotatably connected to the inside of the moving groove. The fixed screw block is slidably connected to the inner wall of the moving groove. The inner side of the inner cylinder is slidably connected to the outer side of the feeding bottom block.

[0007] Preferably, the connecting assembly includes a first sliding step block and a second sliding step block. A groove is provided on the inner side of the inner cylinder. The first sliding step block and the second sliding step block are slidably connected to the inner wall of the groove. The first sliding step block and the second sliding step block are both trapezoidal. The top height of the first sliding step block is higher than the top height of the second sliding step block. The tops of the second sliding step block and the first sliding step block are both inclined.

[0008] Preferably, both ends of the elastic sheet are fixedly connected to elastic side plates, the bottom of the elastic side plates slide against the top of the material delivery block, and the elastic side plates are inclined.

[0009] Preferably, a reserve groove is provided on the side of the outer cylinder away from the discharge pipe, and a reserve window is fixedly connected to the inner wall of the reserve groove. An indicator block is fixedly connected through the inner cylinder on the side away from the discharge pipe, and the indicator block is slidably connected to the inner wall of the reserve groove. The indicator block is designed to be made of transparent material.

[0010] Preferably, a baffle is fixedly connected to one side of the discharge pipe, and the baffle slides and fits against the opening on one side of the inner cylinder.

[0011] Preferably, a scraper is fixedly connected to the top of the inner cylinder opening, and the scraper is slidably connected to the inner side of the baffle.

[0012] Preferably, a feed tube is fixedly connected to the top of the fixed end of the rotary switch, and the feed tube is movably sleeved on the bottom end of the feed tube.

[0013] Preferably, a fixing rod is fixedly connected to the top of the feeding base block. The fixing rod is flat and round. The top of the fixing rod is fixedly connected to the top of the inner wall of the outer cylinder, and the fixing rod is slidably connected to the top of the inner cylinder.

[0014] Preferably, a support base is fixedly connected to the outer side of the outer cylinder, and the support base is arranged in a triangular shape.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. When feeding is required, the inner cylinder moves downward through the moving components inside the outer cylinder. The continuous downward movement of the inner cylinder wall allows the raw materials to be continuously discharged downward and outward. This reduces the impact of bridging effect on feeding without stirring. Furthermore, the movement of the inner cylinder wall induces overall flow, ensuring that the materials added first are used up first, and the materials will not naturally deteriorate due to long-term retention. 2. By setting multiple sets of threaded rods, it is equivalent to applying lifting force from multiple symmetrical points at the same time, which further increases the stability of the inner cylinder movement, making the rising and falling process of the inner cylinder extremely smooth, without abnormal noise, vibration, or tilting, perfectly balancing the load and fundamentally preventing the risk of jamming. 3. Because the elastic sheet is a two-section design, while improving the sealing effect between the inner cylinder and the material delivery base block, the elastic material at the bottom of the elastic sheet can be compressed by sliding step one and sliding step two, and then move towards the center of the material delivery base block. This will push the raw material at the edge towards the inclined recess in the middle for material discharge, further improving the material discharge effect. The elastic side plates fixedly connected to both ends of the elastic sheet can reduce the entry of powdery raw materials into the gap between the elastic sheet and the inner cylinder, and can also push the raw materials for discharge as the elastic sheet squeezes. 4. Through the transparent indicator block and the remaining amount window fixedly connected to one side of the outer cylinder, not only can the remaining amount inside the inner cylinder be accurately recorded, but also when the raw material in the inner cylinder reaches the bottom of the indicator block, the amount of raw material fed at this time accounts for % of the capacity inside the inner cylinder, so as to prevent the inner cylinder from being filled with too much raw material and causing difficulties in feeding. 5. A baffle is fixedly connected to one side of the discharge pipe. The baffle slides and fits against the opening on one side of the inner cylinder, thereby limiting the discharge port so that the discharge port always corresponds to the discharge pipe, and the raw material is always discharged from one point of the discharge pipe.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Reference Figures 1-11 The present invention provides a technical solution: a feeding device for industrial food processing, including an outer cylinder 3 and an inner cylinder 12. A moving component is provided inside the outer cylinder 3, and the inner cylinder 12 is slidably connected to the inner side of the outer cylinder 3 through the moving component. The top of the inner cylinder 12 is closed. The bottom end of the inner cylinder 12 is provided with a material feeding block 10. The top of the material feeding block 10 is a recessed inclined structure. An elastic sheet 11 is provided on the top of the material feeding block 10. The top layer of the elastic sheet 11 is made of rigid material, and the rest is made of elastic material. One side of the top layer slides against the inner wall of the inner cylinder 12, and one end of the bottom layer slides against the top of the inner cylinder 12. The elastic sheet 11 is arranged in a ring shape. A connecting component is provided on the top of the elastic sheet 11 for the elastic sheet 11 to deform. The top of the outer cylinder 3 is fixedly connected to the feed pipe 1, the top of the inner cylinder 12 is fixedly connected to the rotary switch 17, the opening of the rotary switch 17 corresponds to the feed pipe 1, and the side of the outer cylinder 3 is fixedly connected to the discharge pipe 4.

[0020] In the embodiments of the above technical solution, during use, in order to avoid the "bridging" effect affecting the feeding operation of powdered ingredients, it is also not advisable to choose the stirring method to reduce the activity of temperature-sensitive powdered ingredients such as vitamins, probiotics, and protein powder, or to destroy the uniformity of the premix. Therefore, in order to avoid affecting the raw material ratio and activity while facilitating the feeding operation, this device is designed with an outer cylinder 3 and an inner cylinder 12. First, the rotary switch 17 is activated to open the rotary switch 17. At this time, the required powdered ingredients can be introduced into the inner cylinder 12 through the feed pipe 1 and the rotary switch 17, which facilitates the subsequent food raw material addition operation. Usually, the inner cylinder 12 is filled to a position close to the full capacity (e.g., 80%-95%) to avoid the inner cylinder 12 being 100% full of raw materials. After the introduction is completed, the raw materials at the bottom end are filled inside the elastic sheet 11. Then, the rotary switch 17 is closed. The raw materials are sealed through the inner cylinder 12, the rotary switch 17, and the feed block 10 at the bottom end of the inner cylinder 12, thus waiting for the subsequent feeding operation. At this time, the end of the discharge pipe 4 away from the outer cylinder 3 is connected to the external feeding and processing equipment. When a feeding operation is required, the inner cylinder 12 moves downward through the moving components set inside the outer cylinder 3. The continuous downward movement of the inner cylinder 12 generates a continuous and gentle shearing and traction force inside the raw material. This forces the raw material particles to undergo continuous and minute relative movement (misalignment). This micro-movement prevents the particles from tightly binding together to form a stable arch for a long time, keeping them in a "prepared flow" state, thereby achieving the purpose of breaking the arch and allowing the raw material to be continuously discharged downward and outward. Since the raw materials are discharged from the discharge pipe 4 on one side of the bottom of the inner cylinder 12, instead of the traditional center discharge, an asymmetrical flow pattern is created. The raw materials do not shrink uniformly towards the center, but mainly flow to one side. This asymmetrical flow field is not conducive to the formation of a symmetrical and stable arch structure. Therefore, the raw material feeding effect is better. As the inner cylinder 12 continues to move downward, the protruding part can also more intuitively remind the staff of the remaining amount of raw materials inside the inner cylinder 12. This reminds the staff to replenish the amount in time. At the same time, the movement of the inner cylinder wall induces the overall flow, ensuring that the material added first is used up first, and the material will not naturally age and deteriorate due to long-term retention. When the material inside the inner cylinder 12 is about to be discharged, the top of the inner wall groove 19 of the inner cylinder 12 will press down on the connecting component, and the connecting component will force the elastic sheet 11 to flatten and deform. Since the elastic sheet 11 is a two-section design, as the material decreases, the binding force on the bottom end of the elastic sheet 11 decreases, so the elastic material at the bottom end of the elastic sheet 11 will be compressed and then move towards the center of the feeding block 10, thereby scraping the material at the edge towards the inclined recess in the middle to discharge the material, further improving the discharge effect of the material. Moreover, since one side of the top layer of the elastic sheet 11 slides against the inner wall of the inner cylinder 12, it can not only scrape off the powdery material on the inner wall of the inner cylinder 12, but also improve the sealing effect between the inner cylinder 12 and the feeding block 10, reducing the possibility of the material entering the gap between the inner cylinder 12 and the feeding block 10.

[0021] The preferred technical solution in this embodiment is: Reference Figure 2-4 The moving component includes a motor 6 and a threaded rod 8. A fixed cover 2 is fixedly connected to the top of the outer cylinder 3. The motor 6 is fixedly installed inside the fixed cover 2. The top end of the threaded rod 8 is fixedly connected to the bottom of the transmission end of the motor 6. A fixed screw block 13 is fixedly connected to the outer side of the inner cylinder 12. The fixed screw block 13 is threadedly connected to the surface of the threaded rod 8. A moving groove 20 is opened on the inner side of the outer cylinder 3. The threaded rod 8 is rotatably connected to the inside of the moving groove 20. The fixed screw block 13 is slidably connected to the inner wall of the moving groove 20. The inner side of the inner cylinder 12 is slidably connected to the outer side of the feeding bottom block 10.

[0022] The inner cylinder 12 is usually tall and heavy (especially when it is full of materials). Single-point drive is like trying to lift a pencil vertically by pinching the tip of the pencil with your hand. It is easy for it to shake, tilt or even get stuck on the inner wall or guide device. Therefore, by setting multiple sets of threaded rods 8, it is equivalent to applying lifting force from multiple symmetrical points simultaneously. When the inner cylinder 12 is full of raw materials and needs to be moved downwards, the motor 6 drives the threaded rods 8 to move. Thus, the threaded rods 8 drive the inner cylinder 12 to move through the fixed screw block 13. At the same time, because the inner cylinder 12 is slidably connected between the material delivery bottom block 10 and the outer cylinder 3, the material delivery bottom block 10 can also limit the movement of the inner cylinder 12, further increasing the stability of the inner cylinder's movement. This makes the rising and falling process of the inner cylinder extremely smooth, without abnormal noise, vibration, or tilting, perfectly balancing the load and fundamentally preventing the risk of jamming.

[0023] Reference Figure 6 and Figure 8 The connecting components include sliding step block 14 and sliding step block 21. A groove 19 is provided on the inner side of the inner cylinder 12. Sliding step block 14 and sliding step block 21 are slidably connected to the inner wall of the groove 19. Both sliding step block 14 and sliding step block 21 are trapezoidal. The height of the top of sliding step block 14 is higher than the height of the top of sliding step block 21. The tops of sliding step block 21 and sliding step block 14 are inclined.

[0024] Because the bottom of the elastic sheet 11 is designed with elastic material, if the elastic sheet 11 is not limited, not only will the elastic sheet 11 easily fall off, but the bottom of the elastic sheet 11 will also be unable to adhere to the top of the feeding block 10. As a result, it will be impossible to push the raw material toward the center while also being unable to perform the reset operation, and thus it will be impossible to continue the pushing operation. Therefore, sliding step block 14 and sliding step block 21 are fixedly connected to the side of the elastic sheet 11. The elastic sheet 11 can always slide and fit against the inner wall of the inner cylinder 12 through sliding step block 14 and sliding step block 21. Since the top of the material feeding block 10 is a concave inclined structure, the height of the top of sliding step block 14 is higher than the height of the top of sliding step block 21. This ensures that the elastic sheet 11 can perform synchronous scraping operation and avoid mechanical imbalance caused by local deformation differences. Since the tops of sliding step block 21 and sliding step block 14 are both inclined, when the inner cylinder 12 moves downward, the tops of sliding step block 21 and sliding step block 14 can scrape off the raw material on the inner wall of the chute 19, reducing the possibility of raw material residue on the inner wall of the chute 19.

[0025] Reference Figure 6 Both ends of the elastic sheet 11 are fixedly connected to elastic side plates 15. The bottom of the elastic side plate 15 slides against the top of the top sliding step block 14 of the material delivery base block 10. The height of the top of the sliding step block 14 is higher than the height of the top of the sliding step block 21. The elastic side plate 15 is set at an angle.

[0026] Since the filling material is powder, as the powder accumulates, it may be pushed from the open ends of the elastic sheet 11 to the gap between the elastic sheet 11 and the inner cylinder 12, making it difficult to remove and clean. Therefore, elastic side plates 15 are fixedly connected to both ends of the elastic sheet 11 to assist in closing the open ends of the elastic sheet 11. So when the elastic sheet 11 is pressed and deformed, the top of the elastic side plate 15 is simultaneously subjected to extrusion force. Under the action of extrusion force, since the elastic side plate 15 is initially set at an angle and its bottom end is far away from the elastic sheet 11, the bottom end of the elastic side plate 15 will slide away from the elastic sheet 11. At this time, it can further assist in the discharge of raw materials.

[0027] Reference Figure 6 and Figure 10 An excess groove is provided on the side of the outer cylinder 3 away from the discharge pipe 4. An excess window 22 is fixedly connected to the inner wall of the excess groove. An indicator block 18 is fixedly connected through the inner cylinder 12 away from the discharge pipe 4. The indicator block 18 is slidably connected to the inner wall of the excess groove. The indicator block 18 is designed to be made of transparent material.

[0028] Although the amount of raw material remaining inside can be determined by the height of the inner cylinder 12 as it moves downward, it is not accurate enough and requires experience to estimate the approximate amount. Therefore, in order to more intuitively determine the amount of material inside the inner cylinder 12, an indicator block 18 is fixedly connected through the inner cylinder 12 on the side away from the discharge pipe 4, and a reserve window 22 is fixedly connected to the side of the outer cylinder 3. The indicator block 18 moves with the inner cylinder 12, so that the data on the reserve window 22 can be accurately recorded by sliding the indicator block 18 to correspond to the data. Since the material of the indicator block 18 is transparent, the indicator block 18 can also help control the amount of material fed into the inner cylinder 12. When the raw material in the inner cylinder 12 reaches the bottom of the indicator block 18, the amount of raw material fed into the inner cylinder 12 accounts for 80% of the capacity inside the inner cylinder 12, so as to prevent the inner cylinder 12 from being filled with too much raw material and causing difficulty in feeding.

[0029] Reference Figure 2 and Figure 9 A baffle 7 is fixedly connected to one side of the discharge pipe 4, and the baffle 7 slides and fits against the opening on one side of the inner cylinder 12.

[0030] To facilitate material feeding during the downward movement of the inner cylinder 12, one side of the inner cylinder 12 is designed with an opening. Due to the thickness difference between the opening of the inner cylinder 12 and the inner wall of the outer cylinder 3, the raw material will move to the middle between the opening of the inner cylinder 12 and the inner wall of the outer cylinder 3 after being introduced. At this time, as the inner cylinder 12 moves, the raw material inside the inner cylinder 12 may not only be discharged from the discharge pipe 4, but may also be discharged through the space formed by the opening of the inner cylinder 12 and the inner wall of the outer cylinder 3. Therefore, a baffle 7 is fixedly connected to one side of the discharge pipe 4. The baffle 7 slides and fits against the opening on one side of the inner cylinder 12, thereby limiting the discharge port so that the discharge port always corresponds to the discharge pipe 4, so that the raw material is always discharged from the discharge pipe 4.

[0031] Reference Figure 6 A scraper 23 is fixedly connected to the top of the opening of the inner cylinder 12, and the scraper 23 is slidably connected to the inner side of the baffle 7.

[0032] Since the baffle 7 does not move with the inner cylinder 12, in order to reduce the amount of material remaining on the baffle 7, a scraper 23 is fixedly connected to the top of the opening of the inner cylinder 12. By sliding the scraper 23, the material on the surface of the baffle 7 can be scraped off while the inner cylinder 12 moves.

[0033] Reference Figure 6 The top of the fixed end of the rotary switch 17 is fixedly connected to the feed tube 16, which is movably sleeved at the bottom end of the feed tube 1.

[0034] Although the rotary switch 17 corresponds to the feed pipe 1, there is still a possibility that raw materials may remain in the gap between the top of the inner cylinder 12 and the top of the inner wall of the outer cylinder 3 when the raw materials are introduced. In order to reduce the occurrence of this situation, a feed pipe 16 is fixedly connected to the top of the fixed end of the rotary switch 17, so that the feed pipe 16 is movably sleeved at the bottom end of the feed pipe 1. The double-pipe sleeve method can effectively reduce the leakage of powdered raw materials during the feeding process.

[0035] Referring to the figure, a fixing rod 9 is fixedly connected to the top of the feeding base block 10. The fixing rod 9 is flat and round. The top of the fixing rod 9 is fixedly connected to the top of the inner wall of the outer cylinder 3. The fixing rod 9 is slidably connected to the top of the inner cylinder 12.

[0036] To ensure the stability of the material feeding base 10 without affecting the movement and feeding operation of the inner cylinder 12, the material feeding base 10 is connected to the top of the inner wall of the outer cylinder 3 by a fixing rod 9. Since the fixing rod 9 is flat and round, its installation direction is consistent with the mainstream direction of the raw material (i.e., the flat plane is perpendicular to the material flow direction), which greatly reduces the flow resistance, avoids stagnation areas, promotes a smoother "overall flow", ensures the first-in-first-out internal fixing method of materials, and can also further limit the operation of the inner cylinder 12 to improve the stability when the inner cylinder moves downward.

[0037] Reference Figure 1 The outer cylinder 3 is fixedly connected to a support base 5, which is triangular in shape.

[0038] In order to improve the support effect of the device and ensure stable material feeding operation, the support base 5 is set in a triangular shape. This shape is conducive to distributing the force and maintaining the stability of the structure.
