Description

Technical Field

[0001] The invention relates to the technical field of grain processing, in particular to a flour production grinding device and a flour grinding method. Background Art

[0002] Flour production and grinding equipment is a key equipment for grain processing. Its core function is to efficiently and evenly crush wheat and other grain raw materials. The device uses a precisely designed grinding system and rotating grinding rollers or similar mechanisms to apply pressure and shear force to the grains, gradually breaking them up and refining them into flour particles. This process not only ensures the fineness and uniformity of the flour, but also effectively separates products of different particle sizes through auxiliary processes such as screening to meet diverse market demands. In short, flour production and grinding equipment is an indispensable tool for converting grains into high-quality flour. Its efficient and precise crushing and crushing capabilities provide solid support for the development of the flour processing industry.

[0003] However, in the core link of the flour production line, namely the grain feeding and preliminary processing stage, a common and thorny problem is the blockage of the grain feed port. This problem is not only due to the physical properties of the grain during transportation, such as friction and adhesion between particles, but also affected by multiple factors such as equipment design, operating conditions and raw material status. When the grain enters the feed port at a certain speed, due to improper flow control or limitations in equipment design, some grains are prone to accumulate at the entrance and gradually form a blockage. This blockage not only limits the smooth flow of grains, but also may cause stagnation of the entire production line, seriously delaying working hours, affecting production efficiency and product quality. In addition, frequent blockages may also cause unnecessary wear on the equipment, increase maintenance costs and downtime. For this reason, we propose a flour production grinding device and a grinding method. Summary of the invention

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] See also Figure 1-Figure 3The present invention provides a technical solution: a flour production and grinding device and a flour grinding method, comprising a collecting mechanism 1, a crushing mechanism 6 for crushing grains is arranged at the upper end of the collecting mechanism 1, a feeding mechanism 5 for conveying grains to the crushing mechanism 6 is arranged at the upper end of the crushing mechanism 6, a stirring mechanism 4 for stirring and loosening the grains is arranged at the upper end of the feeding mechanism 5, a first supporting mechanism 2 for supporting the stirring mechanism 4, the feeding mechanism 5 and the crushing mechanism 6 is arranged at the upper end of the collecting mechanism 1, a feeding guide mechanism 3 for assisting in the storage of grains is arranged at the center of the upper end of the collecting mechanism 1, and a feeding guide mechanism 4 for assisting in the storage of grains is arranged at the upper end of the collecting mechanism 1. A knocking mechanism 7 for vibrating and compacting the grains is provided on both sides of the collecting mechanism 3, a second supporting mechanism 8 for supporting the two knocking mechanisms 7 is provided on both sides of the upper end of the collecting mechanism 1, a driving mechanism 10 for driving the stirring mechanism 4, the unloading mechanism 5 and the crushing mechanism 6 is provided on one side of the collecting mechanism 1, a transmission mechanism 9 for transmitting kinetic energy is provided on one side of the collecting mechanism 1 close to the driving mechanism 10, and a first synchronization mechanism 11 and a second synchronization mechanism 12 for making the stirring mechanism 4, the unloading mechanism 5 and the crushing mechanism 6 operate synchronously are respectively provided on both sides of the upper end of the collecting mechanism 1.

[0042] Furthermore, the crushing mechanism 6 can realize effective crushing and crushing of the grains to ensure fine and uniform powder quality. At the same time, the introduction of the feeding mechanism 5 realizes the accurate distribution and uniform conveying of the grains, avoids the problems of blockage and oversupply, and further improves the crushing efficiency and the quality of the finished product. The automatic operation of the stirring mechanism 4 not only promotes the uniform mixing of the grains in the pretreatment stage, but also effectively loosens the grain particles through the stirring action, further reducing the blockage caused by the accumulation of grains before crushing. This design significantly improves the efficiency and effect of subsequent crushing operations. The ingenious use of the first synchronous mechanism 11 and the second synchronous mechanism 12 realizes the seamless connection and synchronous operation between the stirring mechanism 4, the feeding mechanism 5 and the crushing mechanism 6. The combined action with the knocking mechanism 7 not only provides a stable feeding path for the grains, but also vibrates and compacts the grains through the knocking action, effectively avoiding the blockage caused by grain accumulation, which helps to improve the subsequent crushing effect and further increases the storage volume of grains before crushing. The entire device adopts a modular design, and the various components are relatively independent and closely connected. This design is convenient for quickly locating problems and repairing and replacing them when failures occur, reducing maintenance costs and time costs; at the same time, the compact structure also reduces the footprint and improves space utilization. The efficient cooperation between the drive mechanism 10 and the transmission mechanism 9 ensures the smooth and reliable operation of the entire system, and improves energy utilization by optimizing the transmission path and reducing transmission losses.

[0043] In the preferred technical solution of this embodiment, please refer to Figure 4As shown, the collecting mechanism 1 includes a supporting frame 101, and a plurality of guide grooves 102 are arranged on both inner walls of the supporting frame 101, a material receiving box 103 is slidably sleeved inside the supporting frame 101, and a plurality of guide rails 104 are arranged and fixedly connected on both sides of the material receiving box 103, and the plurality of guide rails 104 are slidably sleeved inside the plurality of guide grooves 102, and the material receiving box 103 and the supporting frame 101 are detachably connected.

[0044] Furthermore, through the combination of the support frame 101 and the material receiving box 103, it is ensured that the crushed grains can fall into the material receiving box 103 quickly and orderly, effectively avoiding the scattering of grains and mixed impurities, and improving the collection efficiency and grain purity. The guide grooves 102 and guide rails 104 arranged on both sides cooperate with each other to form a stable and smooth sliding system. This design reduces the shaking and friction of the material receiving box 103 during movement, ensures the smooth progress of the collection process, and prolongs the service life of the components. The detachable connection design between the material receiving box 103 and the support frame 101 allows the user to easily clean or replace the material receiving box 103, and can achieve quick disassembly and installation without complicated tools. This not only improves the maintenance efficiency of the equipment, but also facilitates the internal cleaning of the collection mechanism 1 Thorough cleaning can be carried out to prevent mildew or odor problems caused by grain residues. Since the material receiving box 103 can be easily replaced as needed, the collecting mechanism 1 can flexibly adapt to the collection needs of grains of different types and yields. Users can choose appropriate specifications of the material receiving box 103 according to actual conditions to achieve the best collection effect. The structure is compact and occupies a small area, which is conducive to the arrangement of more production equipment or other operations in a limited space. At the same time, the detachable design also reduces material waste, reduces manufacturing costs and the economic burden of users. When the collecting mechanism 1 fails, since the connection between the components is simple and clear, the user can quickly locate the problem and repair or replace it. This design reduces the impact of the failure on the production process and improves the overall reliability and stability of the equipment.

[0045] In the preferred technical solution of this embodiment, please refer to Figure 5 As shown, the first supporting mechanism 2 includes two lower plates 201, and the two lower plates 201 are respectively fixedly connected to the upper end of the supporting frame 101 near two sides thereof, the upper ends of the two lower plates 201 are fixedly connected to the middle plates 202, and the upper ends of the two middle plates 202 are fixedly connected to the upper plates 203, the insides of the two lower plates 201 are fixedly sleeved with first bearings 204 near the two sides, the inside centers of the two middle plates 202 are fixedly sleeved with second bearings 205, and the inside centers of the two upper plates 203 are fixedly sleeved with third bearings 206.

[0046] Furthermore, a stable support structure is formed by a three-layer stacking design of two lower plates 201, a middle plate 202 and an upper plate 203. This structure has high mechanical stability, can effectively resist external loads and vibrations, and ensure the smoothness and safety of the operation of the upper mechanisms. The fixed connection between each layer enables the mixing mechanism 4, the feeding mechanism 5 and the crushing mechanism 6 to be accurately positioned during installation, reducing the risk of performance degradation or failure due to installation errors. At the same time, it also provides convenience for subsequent maintenance and adjustment. The arrangement of the first bearing 204, the second bearing 205 and the third bearing 206 not only provides a stable support structure for the relevant rotating parts, but also provides a stable support structure for the relevant rotating parts. The components provide necessary support and also reduce the stress burden of a single component by dispersing the load, thereby extending the service life of the overall structure. Since the first supporting mechanism 2 provides a stable and adjustable supporting platform, it can easily adapt to the installation requirements of stirring mechanisms 4, feeding mechanisms 5 and crushing mechanisms 6 of different models and configurations. This flexibility provides users with more choices and enhances the scalability and upgrade capabilities of the equipment. The compact structural design enables the first supporting mechanism 2 to provide sufficient support and stability within a limited space, optimizes the spatial layout of the overall equipment, and improves space utilization.

[0047] In the preferred technical solution of this embodiment, please refer to Figure 6-Figure 7As shown, the feed guide mechanism 3 includes two bottom plates 301, both sides of the two bottom plates 301 are fixedly connected to the sides of the two lower plates 201 close to each other, and the two bottom plates 301 are both located at the tops of the two lower plates 201, the upper ends of the two bottom plates 301 close to each other are fixedly connected with arc plates 302, both sides of the two arc plates 302 are fixedly connected to the sides of the two middle plates 202 close to each other, the upper ends of the two arc plates 302 are fixedly connected with inclined plates 303, both sides of the two inclined plates 303 are fixedly connected to the sides of the two upper plates 203 close to each other, and the two inclined plates 303 are both located at the inclined surfaces of the two upper plates 203, the upper ends of the two inclined plates 303 are fixedly connected with guide plates 304, both sides of the two guide plates 304 are fixedly connected to the sides of the two upper plates 203 close to each other, and the two guide plates 304 are both located at the straight surfaces of the two upper plates 203, A frame opening 305 is provided at the center of the two inclined plates 303. A fixed frame bar 306 is fixedly connected to the side of the two inclined plates 303 close to each other. A movable frame bar 307 is installed on the side of the two fixed frame bars 306 close to each other. Two groups of contact edges 308 are provided between adjacent fixed frame bars 306 and movable frame bars 307, and each group of contact edges 308 is fixedly connected to the fixed frame bar 306 and the movable frame bar 307 respectively. Silicon rubber 309 is clamped between adjacent fixed frame bars 306 and movable frame bars 307. A plurality of mounting bolts 3010 are sleeved on the edges of the two movable frame bars 307 in a rectangular arrangement. The assembly ends of the plurality of mounting bolts 3010 respectively penetrate the four groups of contact edges 308 and the two silicone rubbers 309 in sequence and extend to the inside of the two fixed frame bars 306. The two movable frame bars 307 are detachably connected to the two fixed frame bars 306 respectively.

[0048] Furthermore, the feed guide mechanism 3 uses a stacked design to tightly connect the bottom plate 301, the curved plate 302, the inclined plate 303, the guide plate 304 and other components, effectively utilizing the internal space of the equipment, reducing the overall floor space, and improving the space utilization efficiency. Thanks to the clear connection relationship and detachable design between the components, such as the movable frame bar 307 and the fixed frame bar 306 are connected by mounting bolts 3010, so that when the equipment fails, the damaged parts can be quickly located and replaced or repaired, reducing the maintenance difficulty and time cost. The guiding role of the curved plate 302 and the inclined plate 303, and the directional function of the guide plate 304 together constitute an efficient grain flow passage. This design effectively reduces the stagnation and accumulation of grains during the flow process, ensuring that the grains can smoothly enter the next processing link. The rapid tapping action of the tapping mechanism 7 on the silicone rubber 309 can further promote the loosening and uniform distribution of grains near the frame mouth 305. This innovative design effectively avoids the problem of uneven material distribution by the unloading mechanism 5 due to excessive gaps when the grains are stacked, and improves the unloading accuracy and stability. The feed guide mechanism 3 also has the function of temporarily storing grains, which can alleviate the time difference between upstream feeding and downstream processing to a certain extent, and provide a stable material supply guarantee for the unloading mechanism 5, which helps to maintain the continuity and efficiency of the production line.

[0050] Furthermore, the stirring mechanism 4, through its unique spiral design, i.e., the first spiral stirring bar 406 and the second spiral stirring bar 407, can penetrate deep into the grain pile during rotation, effectively break up and stir the grains, thereby avoiding blockage caused by excessive grain accumulation. This design ensures the smooth flow of grains in the equipment and improves the overall processing efficiency. The spiral arrangement of the first spiral stirring bar 406 and the second spiral stirring bar 407 on the support shaft 403 makes the stirring process more comprehensive and uniform. Both light grains and heavy grains can be fully mixed during the stirring process, thereby ensuring the quality consistency of the final product. This uniform stirring ability is crucial for producing high-quality grain mixtures. The design of the stirring mechanism 4 takes into account the characteristics of different types of grains, and the structure of its spiral stirring bars The structure and arrangement make the mechanism suitable for stirring and mixing a variety of grains. Regardless of the grain size, density or humidity, the stirring mechanism 4 can provide an effective stirring effect to meet diverse production needs. The stirring mechanism 4 has relatively few parts, and the connection relationship between the parts is clear. This simple structural design not only reduces the manufacturing cost, but also enables rapid troubleshooting and repair when the equipment fails. In addition, due to the detachability between the parts, it becomes easier and faster to replace worn or damaged parts. The stirring mechanism 4 reduces the residence time and energy consumption of grains in the equipment through an efficient stirring method. At the same time, its compact structural design also reduces the operating resistance of the equipment itself and further improves the energy utilization efficiency. This high efficiency and energy-saving feature helps to reduce production costs and improve economic benefits.

[0051] In the preferred technical solution of this embodiment, please refer to Figure 9-10 As shown, the unloading mechanism 5 includes a first transmission shaft 501, the two ends of the first transmission shaft 501 are respectively fixedly sleeved on the inner rings of the two second bearings 205, a unloading roller 502 is fixedly sleeved on the outer side of the first transmission shaft 501, and the unloading roller 502 is located between the two arc plates 302, and a plurality of unloading troughs 503 are arranged in a ring on the outer side of the unloading roller 502, and the crushing mechanism 6 includes two isolation blocks 604 and two second transmission shafts 601, the bottoms of the two isolation blocks 604 are respectively fixedly connected to the two sides of the top of the support frame 101, the two ends of the two second transmission shafts 601 are respectively fixedly sleeved on the inner rings of the two first bearings 204 on one side and the two first bearings 204 on the other side, and the outer sides of the two second transmission shafts 601 are both fixedly sleeved with squeezing rollers 602, and the outer sides of the two squeezing rollers 602 are both arranged in a ring and fixedly connected with a plurality of crushing teeth 603.

[0052] Furthermore, the feeding mechanism 5 drives the feeding roller 502 to rotate through the first transmission shaft 501, and the specific design of the feeding trough 503 can accurately control the feeding amount of grains. This design helps to maintain the stability of subsequent processing steps and avoid affecting product quality due to uneven feeding amount. The annular arrangement of the feeding trough 503 ensures that the grains can be evenly distributed and fall smoothly during the rotation process, effectively reducing the blockage caused by grain accumulation, which not only improves the feeding efficiency, but also reduces the complexity and cost of equipment maintenance. The crushing mechanism 6 drives the squeezing rollers 602 to rotate relative to each other through the two second transmission shafts 601, and utilizes the squeezing and shearing action of multiple crushing teeth 603 to achieve efficient crushing of grains. The mutual squeezing action of the two squeezing rollers 602 makes the crushing process more direct and efficient, reducing unnecessary energy consumption losses. At the same time, the compact mechanism design reduces the friction resistance and noise level during the operation of the equipment, further improving the energy efficiency and environmental protection performance. The structure of the crushing mechanism 6 is relatively simple and compact, and the connection relationship between the components is clear. This design enables rapid investigation and maintenance when the equipment fails, reducing maintenance costs and downtime.

[0053] In the preferred technical solution of this embodiment, please refer to Figure 11-13 As shown, the two knocking mechanisms 7 and the two second supporting mechanisms 8 are symmetrically arranged with the upper plate 203 as the center, and the knocking mechanism 7 includes two fixed blocks 701, and the two fixed blocks 701 are respectively fixedly connected to the inclined surfaces on one side of the two upper plates 203, and the two fixed blocks 701 are fixedly connected to the side plates 702 on the sides close to each other, and the base plate 703 is fixedly connected between the ends of the two side plates 702 close to each other, and a plurality of uniformly distributed guide tubes 704 are fixedly connected inside the base plate 703, and the plurality of guide tubes 704 are slidably sleeved with impact columns 705, and the centers of the plurality of impact columns 705 are fixedly connected with connecting rods 706, and the other ends of the two side plates 702 are fixedly connected to the base plate 703. A fourth bearing 707 is fixedly sleeved at each of the two fourth bearings 707, and support columns 708 are fixedly sleeved inside the two fourth bearings 707. A crank shaft 709 is fixedly connected between the two support columns 708. A crank connecting rod 7010 distributed evenly is rotatably sleeved on the outer side of the crank shaft 709. The other ends of the multiple crank connecting rods 7010 are rotatably connected to the outer sides of multiple connecting rods 706 respectively. A protective cover 7011 is fixedly sleeved between the outer sides of the two side plates 702. The second supporting mechanism 8 includes a supporting block 801, which is fixedly connected to the top of the bottom plate 301. A supporting groove 802 is penetrated on one side of the inner side of the support block 801, and the support groove 802 is sleeved on the outer side of the protective cover 7011.

[0054] Furthermore, driven by the crank shaft 709 and the crank connecting rod 7010, multiple impact columns 705 can alternately and quickly impact the grain pile. This impact action not only directly acts on the grain particles, but is also transmitted to the entire grain pile through vibration waves, effectively destroying the tight stacking state between the grains and promoting the loosening and uniform distribution of the grains. This innovative design is particularly aimed at the grains near the frame mouth 305, avoiding the problem of uneven material distribution of the feeding mechanism 5 due to excessive gaps or dense stacking, and significantly improving the feeding accuracy and stability. In addition to promoting the loosening of grains, the operation of the knocking mechanism 7 also indirectly enhances the mixing effect between grains. Under the action of impact and vibration, grain particles of different types or different particle sizes can be more fully contacted and mixed, thereby improving the quality consistency of the final product. In addition, the knocking mechanism 7 can loosen and evenly distribute the grains, and significantly reduce the risk of blockage during the transportation and processing of the grains, which helps to maintain the continuous and stable operation of the equipment and improve the overall processing efficiency. The second supporting mechanism 8 provides a stable supporting platform for the knocking mechanism 7 through the supporting block 801 and the supporting groove 802. This supporting structure ensures that the knocking mechanism 7 will not shake or deviate when running at high speed, thereby ensuring that the impact column 705 can act accurately and powerfully on the grain pile, thereby improving the knocking efficiency. The support groove 802 not only plays a role of stable support, but also provides an additional layer of protection barrier for the knocking mechanism 7 by being mounted on the outside of the protective cover 7011, which helps to prevent external impurities or accidental collisions from damaging the knocking mechanism 7, thereby extending its service life.

[0056] Furthermore, the transmission mechanism 9 realizes efficient power transmission through the gear meshing transmission of the two third transmission shafts 905 and the spur gear 906. This design ensures that the energy loss is minimized during the power transmission from the driving mechanism 10 to the squeezing roller 602, thereby improving the operating efficiency of the overall equipment. The design of the transmission mechanism 9 fully considers the space utilization. Through the compact layout of the first docking plate 901, the protective frame 902 and the second docking plate 903, and the firm support of the third transmission shaft 905 by the fifth bearing 904, a high degree of integration of the transmission components is achieved, which not only saves space inside the equipment, but also makes the overall structure more compact and beautiful. The structure of the transmission mechanism 9 is simple and clear, and the connection relationship between the components is clear. When a fault occurs, the problem can be quickly located and repaired, reducing the difficulty and cost of repair. At the same time, the design of the protective frame 902 also effectively prevents external impurities. Interference and damage to transmission components further extend the service life of the equipment. The precise meshing transmission of the spur gear 906 ensures the synchronous rotation and stable output of the third transmission shaft 905. This design reduces vibration and noise during transmission and improves the operating stability and reliability of the equipment, thereby ensuring the efficient grain processing process. The drive mechanism 10 uses a drive motor 1004 as a power source, and its output end is directly connected to the third transmission shaft 905, providing strong power support for the entire transmission system. This design ensures that the equipment can easily cope with various grain processing needs during operation and improves work efficiency. The drive mechanism 10 is fixedly connected to the second docking plate 903 through the mounting plate 1001. At the same time, the design of the positioning plate 1002 and multiple reinforcing ribs 1003 also enhances the stability and reliability of the drive mechanism 10, ensuring its safety performance during operation.

[0058] Furthermore, the first synchronization mechanism 11 realizes precise synchronization between the crushing mechanism 6, the stirring mechanism 4 and the feeding mechanism 5 through the cooperation of the first sprocket 1101, the second sprocket 1102, the third sprocket 1103 and the fourth sprocket 1104 with the first chain 1105 and the second chain 1106. This synchronization mechanism ensures the coordination and consistency of each mechanism during operation, and avoids performance degradation or equipment damage caused by speed mismatch. Chain drive, as an efficient transmission method, has the characteristics of large power transmission, high efficiency and reliable operation. The first synchronization mechanism 11 adopts a chain transmission method, which not only realizes the stable transmission of power, but also reduces the energy loss in the transmission process, and improves the operation efficiency of the overall equipment.
