Description

Technical Field

[0001] The present invention relates to the technical field of medicinal material processing, and specifically relates to a Pueraria lobata grinder. Background Art

[0002] In the fields of Chinese herbal medicine processing and food deep processing, Pueraria lobata is widely used in the development of medicine and food homologous products because it is rich in starch, polysaccharides and various bioactive ingredients. To achieve the pulverization, extraction or component separation of Pueraria lobata, the original root materials need to be fully ground and screened first. However, Pueraria lobata has a tough texture, a high fiber content, and contains more moisture, and conventional pulverizing devices are difficult to achieve efficient refinement without damaging the active ingredients.

[0003] Existing Pueraria lobata grinding equipment usually adopts a unidirectional rotating blade or grinding wheel structure, with a fixed grinding path. During the processing, it is easy for Pueraria lobata fibers to entangle the cutting tools or block the discharge port, affecting the continuous operation of the equipment and the final pulverization fineness. At the same time, in order to cooperate with subsequent separation or extraction processes, the ground materials need to be subjected to particle grading and screening. However, most traditional screening devices are rigid sieves plus eccentric vibration motors, and the vibration frequency of the sieve surface is unstable. The materials do not move sufficiently on the sieve surface, and it is easy to occur problems such as sieve hole blockage or low screening efficiency, resulting in uneven particle size distribution of the products and affecting the quality consistency.

[0004] In addition, some equipment treats grinding and screening as two independent modules, which not only has a complex structure, occupies a large space, and has high energy consumption, but also is not conducive to the timely transition and coordinated operation between the grinding and screening links, increasing the risk of intermediate storage and secondary pollution.

[0005] Therefore, there is an urgent need for a Pueraria lobata grinding equipment with a compact structure, strong linkage, suitable for the grinding characteristics of fibrous materials, and at the same time having an efficient screening function, which can achieve automatic screening and discharging while improving the pulverization accuracy, optimize the processing flow, improve production efficiency and product quality, and meet the actual needs of the Chinese herbal medicine and food industries for fine processing of raw materials. Summary of the Invention

[0006] Aiming at the deficiencies of the existing technology, the purpose of the embodiments of the present invention is to provide a Pueraria lobata grinder to solve the problems in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions: A Pueraria lobata grinder includes a device housing, and a feed inlet is provided on the device housing. It further includes: A grinding mechanism, the grinding mechanism is arranged inside the device housing, the grinding mechanism is symmetrically arranged with respect to the device housing, the grinding mechanism includes a mounting sleeve, a rotating assembly, a redirecting assembly and grinding blades, one end of the mounting sleeve is movably connected to the inner wall of the device housing, a rotating assembly is arranged inside the mounting sleeve, the rotating assembly is movably connected to the mounting sleeve, a redirecting assembly is arranged inside the rotating assembly, a grinding blade is arranged at one end of the redirecting assembly, and the redirecting assembly penetrates through the mounting sleeve; A screening mechanism, the screening mechanism is arranged below the grinding mechanism, and the screening mechanism is mounted inside the device housing; The power rod is used as a power member. When the power rod is started, the power rod drives the mounting sleeve to rotate. Since the mounting rod penetrates through the mounting sleeve, the mounting sleeve can drive the mounting rod to rotate when the mounting sleeve rotates. At this time, since an arc-shaped mounting plate is mounted on one side of the mounting rod, the arc-shaped mounting plate rotates simultaneously. Guide blocks are symmetrically arranged on the side surface of the arc-shaped mounting plate; Since the guide blocks are of a cylindrical structure, and the triangular redirecting plate is located below the guide groove, and at the same time the guide groove and the redirecting plate form a channel, the structure of the channel is a triangular structure, one on top and the other at the bottom. When the guide blocks pass through the channel, the front and rear order of the symmetrically arranged guide blocks can be changed. After the change, the mounting rod rotates, and at this time the mounting rod drives the grinding blades to rotate, realizing the grinding effect.

[0008] As a further solution of the present invention, the rotating assembly includes a power rod and an inner sleeve. One end of the power rod is fixedly connected to the mounting sleeve, the power rod drives the mounting sleeve to rotate, and the other end of the power rod is connected to the inner sleeve; As a further solution of the present invention, the redirecting assembly includes a guide groove, a redirecting plate, guide blocks, an arc-shaped mounting plate and a mounting rod. The guide groove is arranged on the side surface of the inner sleeve, the guide groove is triangular, a redirecting plate is arranged inside the inner sleeve, one end of the redirecting plate is fixedly connected to the inner wall of the inner sleeve, the other end of the redirecting plate is triangular, the triangular redirecting plate is located below the guide groove, and at the same time the guide groove and the redirecting plate form a channel, the channel is movably connected to the guide blocks, the guide blocks are symmetrically arranged with respect to the arc-shaped mounting plate, and a mounting rod is arranged on one side of the arc-shaped mounting plate, and the mounting rod penetrates through the mounting sleeve.

[0009] As a further solution of the present invention, the grinding blades are of an arc-shaped structure, and adjacent grinding blades do not interfere with each other.

[0010] As a further solution of the present invention, the redirecting plate is of an L-shaped structure.

[0011] As a further solution of the present invention, the screening mechanism includes: Installation base plate, the installation base plate is fixedly connected to the device housing, and a screening component is arranged on the installation base plate; Vibrating screening component, the vibrating screening component is arranged on the screening component, and the vibrating screening component is located at the central position of the screening component.

[0012] As a further scheme of the present invention, the vibrating screening component includes: Power component, the power component is arranged on the mounting plate, the mounting plate is fixedly connected to the screening component, and the mounting plate is located at the central position of the screening component; Swinging component, the swinging component is symmetrically arranged with respect to the power component, the swinging component is connected to the output end of the power component, and the swinging component is of a fan-shaped structure.

[0013] As a further scheme of the present invention, the screening component includes: Screening plate, the mounting plate is fixedly connected to the screening plate, and the mounting plate is located at the central position of the screening plate; Screening holes, the screening holes are evenly distributed with respect to the screening plate; Mounting blocks, the mounting blocks are symmetrically arranged with respect to the screening plate, the mounting blocks are fixedly connected to the screening plate, and the mounting blocks are fixedly connected to the installation base plate; Elastic plate, the elastic plate is arranged between the vertically adjacent mounting blocks.

[0014] In summary, compared with the prior art, the embodiments of the present invention have the following beneficial effects: By setting the grinding mechanisms symmetrically on both sides, the present invention realizes the symmetric two-way grinding operation, significantly improving the overall processing capacity. The rotating component in the grinding mechanism drives the installation sleeve to rotate through the power rod, and then drives the installation rod and the grinding blade in the redirecting component to perform a rotating motion. In particular, the special channel structure formed by the triangular guiding groove on the side wall of the inner sleeve and the triangular redirecting plate can automatically change the front and rear positions of the guiding block when it passes through, realizing the disturbing rotation of the installation rod, and making the grinding blade generate periodic redirection or vibrating rotary cutting, greatly enhancing the grinding efficiency and uniformity of the material, and being particularly suitable for Pueraria lobata raw materials with longer fibers or harder textures.

[0015] Secondly, the grinding blade adopts an arc structure, and adjacent blades do not interfere with each other during the movement. At the same time, through the linkage of the guiding block and the redirecting plate, the rotary cutting action shows disturbance and variable directions, effectively preventing the material from winding or accumulating between the blades, improving the continuity and stability of the processing process, and prolonging the service life of the blade.

[0016] Again, in terms of the subsequent grinding process, the present invention provides a highly integrated material screening mechanism. Among them, the screening assembly includes a screening plate with multiple groups of screening holes, which can automatically classify according to the particle size. The fine powder directly falls into the lower collection area, while the large particles remain on the screening surface and continue to be screened. A vibrating screening assembly is arranged in the center of the screening assembly. Centered on the power component, vibration is output through symmetrically arranged fan-shaped swing components, and combined with the elastic plate at the lower part of the screening plate for flexible support, ensuring that the screening plate generates multi-frequency micro-vibrations in the horizontal direction, thereby realizing the rapid loosening, movement and perforation of materials on the screening surface, greatly improving the screening efficiency and accuracy.

[0017] In addition, the distribution structure of the elastic plate and the mounting block provides balanced and buffered support force for the sieve plate, effectively reducing vibration loss and operating noise while ensuring the structural rigidity of the equipment, and significantly improving the equipment stability and operating life.

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0028] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0029] In one embodiment, a kudzu grinder, see Figures 1 to 7 , includes a device housing 1, a feed inlet 2 is provided on the device housing 1, and further includes: A grinding mechanism 4, the grinding mechanism 4 is arranged inside the device housing 1, the grinding mechanism 4 is symmetrically arranged with respect to the device housing 1, the grinding mechanism 4 includes a mounting sleeve 41, a rotating assembly 42, a redirecting assembly 43 and a grinding blade 44, one end of the mounting sleeve 41 is movably connected to the inner wall of the device housing 1, a rotating assembly 42 is arranged inside the mounting sleeve 41, the rotating assembly 42 is movably connected to the mounting sleeve 41, a redirecting assembly 43 is arranged inside the rotating assembly 42, a grinding blade 44 is arranged at one end of the redirecting assembly 43, and the redirecting assembly 43 penetrates through the mounting sleeve 41; A screening mechanism 3, the screening mechanism 3 is arranged below the grinding mechanism 4, and the screening mechanism 3 is mounted inside the device housing 1; The rotating assembly 42 includes a power rod 421 and an inner sleeve 422, one end of the power rod 421 is fixedly connected to the mounting sleeve 41, the power rod 421 drives the mounting sleeve 41 to rotate, and the other end of the power rod 421 is connected to the inner sleeve 422; The redirecting component 43 includes a guiding groove 431, a redirecting plate 432, a guiding block 433, an arc-shaped mounting plate 434 and a mounting rod 435. The guiding groove 431 is arranged on the side surface of the inner sleeve 422. The guiding groove 431 is triangular. A redirecting plate 432 is arranged inside the inner sleeve 422. One end of the redirecting plate 432 is fixedly connected to the inner wall of the inner sleeve 422. The other end of the redirecting plate 432 is triangular. The triangular redirecting plate 432 is located below the guiding groove 431. At the same time, the guiding groove 431 and the redirecting plate 432 form a channel, and the channel is movably connected to the guiding block 433. The guiding blocks 433 are symmetrically arranged with respect to the arc-shaped mounting plate 434. One side of the arc-shaped mounting plate 434 is provided with a mounting rod 435, and the mounting rod 435 penetrates through the mounting sleeve 41; The power rod 421 serves as a power component. When the power rod 421 is started, the power rod 421 drives the mounting sleeve 41 to rotate. Since the mounting rod 435 penetrates through the mounting sleeve 41, when the mounting sleeve 41 rotates, it can drive the mounting rod 435 to rotate. At this time, since an arc-shaped mounting plate 434 is installed on one side of the mounting rod 435, the arc-shaped mounting plate 434 rotates simultaneously. The guiding blocks 433 are symmetrically arranged on the side surface of the arc-shaped mounting plate 434; Since the guiding block 433 adopts a cylindrical structure, and the triangular redirecting plate 432 is located below the guiding groove 431. At the same time, the guiding groove 431 and the redirecting plate 432 form a channel, so that the structure of the channel is a triangular structure, one on top and the other at the bottom. When the guiding block 433 passes through the channel, the front-back order of the symmetrically arranged guiding blocks 433 can be changed. After the change, the mounting rod 435 rotates, and at this time the mounting rod 435 drives the grinding blade 44 to rotate, realizing the grinding effect.

[0030] In this embodiment, the grinding blade 44 adopts an arc-shaped structure, and adjacent grinding blades 44 do not interfere with each other. The power rod 421 serves as a power component. When the power rod 421 is started, the power rod 421 drives the mounting sleeve 41 to rotate. Since the mounting rod 435 penetrates through the mounting sleeve 41, when the mounting sleeve 41 rotates, it can drive the mounting rod 435 to rotate. At this time, since an arc-shaped mounting plate 434 is installed on one side of the mounting rod 435, the arc-shaped mounting plate 434 rotates simultaneously. The guiding blocks 433 are symmetrically arranged on the side surface of the arc-shaped mounting plate 434; Since the guiding block 433 adopts a cylindrical structure, and the triangular redirecting plate 432 is located below the guiding groove 431. The redirecting plate 432 adopts an L-shaped structure. At the same time, the guiding groove 431 and the redirecting plate 432 form a channel, so that the structure of the channel is a triangular structure, one on top and the other at the bottom. When the guiding block 433 passes through the channel, the front-back order of the symmetrically arranged guiding blocks 433 can be changed. After the change, the mounting rod 435 rotates, and at this time the mounting rod 435 drives the grinding blade 44 to rotate, realizing the grinding effect.

[0031] The switching of the position sequence of the guiding blocks further affects the rotation direction or angle of the mounting rod 435, causing the mounting rod 435 to rotate stably or vibrate periodically. Since the mounting rod 435 is directly connected to the grinding blade 44, the movement of the mounting rod 435 will be directly transmitted to the grinding blade 44, enabling it to rotate or perform disturbing rotary cutting in three-dimensional directions, thereby fully, evenly, and efficiently grinding the material to be processed.

[0032] During the entire grinding process, the rotating assembly 42 realizes the basic rotation drive, and the direction-changing assembly 43 changes the movement trajectory of the guiding blocks through geometric structure conversion, realizing intermittent or disturbing rotation control of the grinding blade 44, further enhancing the crushing efficiency and refinement uniformity during the grinding process, and effectively improving the overall grinding performance of the device.

[0033] In one embodiment, referring to Figures 1 to 7 , the screening mechanism 3 includes: A mounting base plate 31, the mounting base plate 31 is fixedly connected to the device housing 1, and a screening assembly 33 is arranged on the mounting base plate 31; A vibrating screening assembly 32, the vibrating screening assembly 32 is arranged on the screening assembly 33, and the vibrating screening assembly 32 is located at the central position of the screening assembly 33.

[0034] Further, referring to Figures 1 to 7 , the vibrating screening assembly 32 includes: A power member 321, the power member 321 is arranged on a mounting plate 323, the mounting plate 323 is fixedly connected to the screening assembly 33, and the mounting plate 323 is located at the central position of the screening assembly 33; A swinging member 322, the swinging member 322 is symmetrically arranged with respect to the power member 321, the swinging member 322 is connected to the output end of the power member 321, and the swinging member 322 is in a sector structure.

[0035] Further, referring to Figures 1 to 7 , the screening assembly 33 includes: A screening plate 331, the mounting plate 323 is fixedly connected to the screening plate 33, and the mounting plate 323 is located at the central position of the screening plate 33; Screening holes 332, the screening holes 332 are evenly distributed with respect to the screening plate 331; Mounting blocks 333, the mounting blocks 333 are symmetrically arranged with respect to the screening plate 331, the mounting blocks 333 are fixedly connected to the screening plate 331, and the mounting blocks 333 are fixedly connected to the mounting base plate 31; Elastic plates 334, the elastic plates 334 are arranged between the vertically adjacent mounting blocks 333.

[0036] In this embodiment, the power component 321 is a motor with output ends provided on both sides. Starting the power component 321 causes the swing components 322 provided on both sides to rotate. When the device operates and enters the material screening stage, the screening mechanism 3 is fixed in the device housing 1 through the mounting base plate 31 to provide overall structural support. After the material is ground by the grinding mechanism, it falls into the screening assembly 33 and is ready for particle size sorting.

[0037] A plurality of screening holes 332 are evenly distributed on the screening plate, which are used to classify the ground material according to particle size. The material with a particle size smaller than the sieve hole will fall through the screening holes 332 to the lower collection area, while the larger particles larger than the sieve hole remain on the surface of the screening plate 331 and continue to be vibrated and screened.

[0038] To improve the screening efficiency and uniformity, after the vibrating screening assembly 32 provided at the center of the screening assembly 33 is started, the power component 321 first generates vibration output. The power component 321 is fixedly installed on the mounting plate 323 at the center of the screening assembly, and its output end is connected to the swing component 322 with a fan-shaped structure. The swing components 322 are symmetrically arranged on both sides of the power component and start to swing in a fan shape with the drive of the power component.

[0039] The left-right alternating movement of the swing component 322 transmits the vibration force to the screening plate 331, and forms regular elastic vibration in cooperation with the elastic plate 334. The elastic plate 334 is arranged between a plurality of symmetric mounting blocks 333 under the screening plate, and provides flexible support and buffering when the screening plate is vibrated, so that the screening plate generates slight bouncing and multi-frequency micro-vibration movements in the horizontal direction, further enhancing the looseness and mobility of the material.

[0040] Through this combination method of "central drive + circumferential elastic support + sieve hole screening", the material obtains sufficient vibration excitation on the screening plate 331, quickly disperses, rolls and perforates during the screening process, effectively preventing the problem of reduced screening efficiency caused by material accumulation, blockage or adhesion, and realizing continuous, stable and efficient particle screening operation.

[0041] The working principle of the present invention is: The power rod 421 drives the mounting sleeve 41 to rotate. Since the mounting rod 435 passes through the mounting sleeve 41, the mounting sleeve 41 can drive the mounting rod 435 to rotate when it rotates. At this time, since an arc-shaped mounting plate 434 is installed on one side of the mounting rod 435, the arc-shaped mounting plate 434 rotates simultaneously. Guide blocks 433 are symmetrically arranged on the side surface of the arc-shaped mounting plate 434; Since the guiding block 433 has a cylindrical structure, and the triangular redirecting plate 432 is located below the guiding groove 431, the redirecting plate 432 has an L-shaped structure. At the same time, the guiding groove 431 and the redirecting plate 432 form a channel, so that the structure of the channel is a triangular structure, one above the other. When the guiding block 433 passes through the channel, the front and rear order of the symmetrically arranged guiding blocks 433 can be changed. After the change, the mounting rod 435 rotates, and at this time, the mounting rod 435 drives the grinding blade 44 to rotate, achieving the grinding effect.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
