Abstract
Description
Technical Field
[0001] This utility model relates to the field of flour processing, and in particular to a high-efficiency bran screening and separation device for flour processing. Background Technology
[0002] Flour is a powdery substance made from wheat. During the flour processing, a professional bran separator is usually used to precisely separate the wheat bran, so that the bran can be effectively separated from the flour, thus laying a solid foundation for the subsequent production of high-quality flour.
[0003] In actual production, materials (a mixture of flour and bran) are usually poured directly into the feed inlet into the screening and separation machine. Due to the lack of precise control over the feeding speed and flow rate, excessive material is often fed at once. When a large amount of material floods into the device in a short period of time, it is easy to exceed the processing capacity of the device. In some simple screening and separation equipment used in small flour processing plants, because there is no dedicated quantitative feeding mechanism, when too much material is poured in at once, the material will quickly accumulate in the feeding area, thereby blocking the subsequent screening channels or separation components, making it impossible for the material to be screened and separated smoothly, and reducing the screening and separation efficiency of the device. To address this problem, a high-efficiency bran screening and separation device for flour processing is proposed. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a high-efficiency bran screening and separation device for flour processing, which aims to improve the problem in the prior art that "if too much material is fed at one time, the material will quickly accumulate in the feeding area, which will prevent the material from being screened and separated smoothly and reduce the screening and separation efficiency of the device".

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0031] Reference Figure 1 - Figure 3This utility model provides an embodiment of a high-efficiency bran screening and separation device for flour processing, including a separator housing 1, which is capable of screening and separating bran internally. This technology is prior art and will not be described in detail. A feed hopper 2 is fixedly connected to the upper side of the separator housing 1 to receive the mixture of flour and bran to be screened and separated, providing a material inlet for the entire screening and separation process. A metering mechanism is provided inside the feed hopper 2, which includes a dispensing component and an adjusting component. The dispensing component includes a dispensing element 31, which is driven by a servo motor 6. The rotation changes the relative position of the channel and the material in the feed hopper 2, thereby regulating the speed and flow rate of the material entering the separator shell 1. The outer side of the material distribution component 31 is arc-shaped and can rotate on the lower inner wall of the feed hopper 2 to adjust the lower part of the feed hopper 2. The material distribution component 31 is rotatably connected to the inner wall of the feed hopper 2, and a channel is opened through the middle of the material distribution component 31. A servo motor 6 is fixedly connected to the right side of the separator shell 1 near the material distribution component 31 to provide the rotation power for the material distribution component 31. This technology is existing technology, so it will not be described in detail.
[0032] Furthermore, the output shaft of the servo motor 6 is fixedly connected to the right side of the material distribution component 31 on the left. A moving block 32 is slidably connected to the inner wall of the material distribution component 31. Two sets of moving blocks 32 are arranged symmetrically. By adjusting their positions within the material distribution component 31, the effective cross-sectional area of the channel can be changed. For example, when the two sets of moving blocks 32 are close to each other, the channel narrows and the material throughput decreases; when they are far apart, the channel widens and the material throughput increases. A toothed plate 33 is fixedly connected to the front of the left set of moving blocks 32, and a toothed plate 35 is fixedly connected to the front of the right set of moving blocks 32. A toothed column 34 is rotatably connected to the inner wall of the material distribution component 31. The outer side of the toothed column 34 meshes with the toothed plate 33 and the toothed plate 35. Through the meshing relationship, when the toothed plate 33 moves, it can drive the toothed column 34 to rotate, thereby driving the toothed plate 35 to move, thus realizing the synchronous relative movement of the two sets of moving blocks 32 and precisely adjusting the channel size.
[0033] Reference Figure 2 - Figure 4The adjustment assembly includes an adjustment bolt 36. The outer side of the adjustment bolt 36 is threadedly connected to the inner wall of the left side of the material distribution component 31, and the right side of the adjustment bolt 36 is rotatably connected to the inner wall of the left side of the moving block 32. By rotating the adjustment bolt 36, the moving block 32 can be pushed to slide within the material distribution component 31 due to the action of the threads, thereby achieving a more precise adjustment of the position of the moving block 32. This further precisely controls the quantitative supply of materials, effectively preventing excessive feeding of raw materials and bran at one time, which could cause equipment blockage and improve the efficiency of bran screening and separation. A crank is provided on the left side of the adjustment bolt 36 for easy manual rotation by the operator. A positioning rod 4 is fixedly connected to the inner wall of the material distribution component 31. The positioning rod 4 is slidably connected to the inner wall of the moving block 32, guiding and limiting the sliding of the moving block 32. This ensures that the moving block 32 can only move in a straight line along the direction of the positioning rod 4 within the material distribution component 31, guaranteeing the stability and accuracy of the material distribution process.
[0034] Reference Figure 1 , Figure 2 and Figure 5 A toggle assembly is provided on the upper side of the feed hopper 2. The toggle assembly includes a protective shell 51, which is fixedly connected to the outside of the feed hopper 2. The protective shell 51 protects the internal gear ring 52 and prevents external impurities from entering and affecting the normal operation of the gear ring 52. It also provides a certain space restriction and support for the rotation of the gear ring 52. The gear ring 52 is rotatably connected to the outside of the feed hopper 2, which transmits the power of the drive motor 55 to the material-pushing rod 53, so that it can push the material in the feed hopper 2. The lower side of the gear ring 52 is attached to the inner side of the protective shell 51. The top of the gear ring 52 is fixedly connected to the material-pushing rod 53. The material-pushing rod 53 is set inside the feed hopper 2 and stirs and pushes the flour and bran mixture entering the feed hopper 2. It prevents the material from accumulating or forming voids in the feed hopper 2, so that the material can enter the channel of the material distribution component 31 more evenly, ensuring the accuracy and stability of quantitative material distribution, effectively preventing the equipment blockage caused by too much raw material and bran being fed at one time, and improving the efficiency of bran screening and separation.
[0035] Furthermore, a drive motor 55 is fixedly connected to the lower right side of the protective shell 51. Through the meshing transmission of gear 54 and gear ring 52, the gear ring 52 is driven to rotate, thereby causing the material-pulling rod 53 to perform material-pulling operation in the feed hopper 2. The top of the output shaft of the drive motor 55 is fixedly connected to the gear 54, which meshes with the outside of the gear ring 52, transmitting the power generated by the drive motor 55 to the gear ring 52, thereby driving the material-pulling rod 53, which is fixedly connected to the top of the gear ring 52, to make a circular motion inside the feed hopper 2. This effectively prevents the equipment from being blocked due to excessive feeding of raw materials and bran at one time, and improves the efficiency of bran screening and separation.
[0036] Working principle: When in use, the mixture of flour and bran is first poured into the feed hopper 2. The drive motor 55 fixed on the protective shell 51 is started, and the gear 54 at the top of its output shaft rotates accordingly. The drive gear ring 52 starts to rotate, which in turn drives the material pusher rod 53 fixed at the top of the gear ring 52 and located inside the feed hopper 2 to make a circular motion. The material pusher rod 53 stirs and pushes the material in the feed hopper 2 to prevent the material from accumulating or forming voids, so that the material is evenly distributed and prepared for subsequent quantitative dispensing.
[0037] Next, the material distribution component 31 can rotate under the drive of the servo motor 6, changing the relative position of the material in the central through channel and the feed hopper 2, thereby adjusting the speed and flow rate of the material entering the separator shell 1. At the same time, rotating the adjusting bolt 36 can push the left moving block 32 to slide along the positioning rod 4 inside the material distribution component 31, causing the toothed plate 33 to move, driving the toothed column 34 to rotate, and then driving the toothed plate 35 to move, realizing the synchronous relative movement of the two sets of moving blocks 32, further precisely controlling the channel size to achieve the purpose of precise quantitative material distribution, effectively preventing the equipment from being blocked due to excessive feeding of raw materials and bran at one time, and improving the efficiency of bran screening and separation.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
