Description

Technical Field

[0001] The invention relates to the technical field of Chinese medicinal material processing, and in particular to a Chinese medicinal material stirring and mixing device. Background Art

[0002] Chinese medicinal materials refer to native medicinal materials used under the guidance of traditional Han medicine for the treatment of diseases. There are many types of Chinese medicinal materials with a wide range of sources, including roots, stems, leaves, flowers, fruits, seeds of plants, and certain parts of animals and minerals. According to their sources and properties, Chinese medicinal materials can be divided into three categories: botanicals, animal medicines and mineral medicines. Chinese medicinal materials have multiple functions and effects. Different Chinese medicinal materials have different pharmacological effects and indications. Chinese medicinal material stirring and mixing devices are equipment used for mixing and homogenizing Chinese medicinal material powders, granules and other materials. These devices are widely used in traditional Chinese medicine pharmaceutical, food processing, chemical industry and other fields. Chinese medicinal material stirring and mixing devices can ensure that the materials are highly uniform during the mixing process and improve product quality.

[0003] After searching, the Chinese patent with publication number CN115869804A discloses a stirring and mixing device for Chinese herbal medicine, including a tank body, a control chamber is provided on the tank body, a bearing is fixedly connected to the tank body, the tank body is rotatably connected to an outer rod through the bearing, a driven rod is slidably connected to the outer rod, a pull rod is rotatably connected to the top of the driven rod, a rod sleeve is sleeved on the pull rod, the rod sleeve is rotatably connected to the control chamber, the driven rod is specifically composed of an upper section and a lower section, the upper section is specifically a gear, and the lower section is specifically a pentagonal prism; the advantages of the present invention compared with the prior art are: the present invention can control the stirring frequency by controlling the pull rod, and when the pull rod is pushed up, when the motor rotates forward, the inner wall of the tank body can be cleaned by a scraper to remove the sediment adhered to the inner wall of the tank body; when the motor rotates reversely, the inside of the tank body can be filtered and precipitated, and the device is simple to operate and has good application value; however, the above scheme still has the following shortcomings when it is actually used:

[0004] In the Chinese medicinal materials processing industry, the mixing and stirring of powdered Chinese medicinal materials is a crucial link, which is directly related to the quality and efficacy of the final product. However, in the actual operation process, when a large amount of powdered Chinese medicinal materials is added to the mixing tank at one time, due to the significant surface adsorption and mutual interaction of the powder particles themselves, these characteristics make the powder particles quickly adsorb to each other and form tightly bound clumps once they come into contact with the solvent without sufficient pretreatment, especially when the wettability and penetration properties of the solvent are insufficient. These clumps are not only difficult to disperse effectively during the stirring process, but also seriously hinder the uniform penetration and dissolution of the solvent into the Chinese medicinal materials, thereby significantly reducing the stirring efficiency and affecting the uniformity of the drug components. Uniformity and extraction rate of active ingredients; in addition, the natural properties of Chinese medicinal materials determine that they inevitably contain a certain amount of impurities, such as sand and gravel, incompletely crushed rhizome fragments or other large foreign matter. If these large foreign matter are directly added to the mixing tank without proper pretreatment and screening, they will act as "obstacles" in the mixing process, which will not only increase the mechanical load of the mixing system and aggravate the wear of the mixing equipment, but may also destroy the stability of the mixing process, resulting in uneven mixing of the mixed liquid, stratification, and even blockage of the agitator. What is more serious is that the presence of these large foreign matter may also have an adverse effect on subsequent product filtration, purification and other process steps, ultimately affecting the purity and safety of the product.

[0005] Therefore, the present application provides a Chinese medicinal material stirring and mixing device. Summary of the invention

[0042] Beneficial effects of the present invention:

[0043] 1. The Chinese medicinal material stirring and mixing device is provided with a stirring motor and a support plate. Through the cooperation of the stirring motor with the stirring rod, the driving block, the one-way tooth plate and other components, when the stirring motor rotates in the forward direction, the one-way tooth plate is made to slide back and forth by the action of the supporting spring 2, and the movable plate is pushed to generate vibration, thereby driving the Chinese medicinal materials on the screening plate to be vibrated and screened. This dynamic screening method not only breaks the static balance between the Chinese medicinal material powder particles, but also promotes the mutual movement and dispersion between the particles, and effectively avoids the agglomeration phenomenon caused by surface adsorption and mutual force. At the same time, the fine sieve holes on the screening plate effectively intercept large particles of foreign matter in the Chinese medicinal materials, ensuring that only qualified materials enter the stirring tank for further mixing, thereby further optimizing the stirring effect and avoiding the problems of stirring dead corners and uneven mixing caused by material accumulation or uneven distribution.

[0044] 2. This Chinese medicinal material stirring and mixing device is provided with a stirring motor, a one-way tooth plate and a one-way tooth groove. When the stirring motor is reversed, the locking direction of the one-way tooth plate and the one-way tooth groove causes the movable disk, the supporting spring and the one-way bearing to rotate as a whole, thereby driving the screening plate to rotate, and utilizing centrifugal force to effectively discharge large particle materials into the aggregate frame through the connecting port, so as to facilitate subsequent processing or re-screening, thereby improving the automation degree and operation convenience of the equipment, and effectively solving the problem that large particle materials are difficult to efficiently remove in the traditional screening process, and reducing the need for manual intervention and labor intensity. At the same time, the timely collection of the aggregate frame also provides convenience for subsequent further processing or re-screening of large particle materials, thereby ensuring the continuity and efficiency of the entire Chinese medicinal material processing process.

[0045] 3. This Chinese medicinal material stirring and mixing device, by setting a feeding box and a feeding assembly, drives two feeding rollers to rotate in opposite directions through a feeding motor, and the Chinese medicinal materials enter the feeding box evenly and controllably in the gap between the two, and then enter the stirring and screening system. The entire feeding process not only achieves a high degree of automation and significantly reduces the burden of manual operation, but more importantly, it gives the operator the ability to accurately control the feeding speed. The operator can flexibly adjust the speed of the feeding motor according to production needs and the characteristics of the Chinese medicinal materials, and then control the rotation speed of the two feeding rollers. This fine-tuning mechanism ensures that the Chinese medicinal materials can enter the stirring and screening system at the optimal speed, which not only avoids problems such as blockage and uneven mixing caused by too fast feeding, but also effectively prevents low production efficiency caused by insufficient feeding.

[0055] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0057] like Figures 1 to 6As shown, a Chinese medicinal material stirring and mixing device comprises a stirring tank 1, the top outer wall of the stirring tank 1 is provided with a liquid adding pipe 13, and the liquid adding pipe 13 is connected to the stirring tank 1; a connecting shell 2 is fixedly installed on the top of the stirring tank 1; a feeding box 3 is arranged on the top surface of the connecting shell 2, and the feeding box 3 is connected to the connecting shell 2; a stirring rod 4 is rotatably installed on the inner side wall of the stirring tank 1; a plurality of stirring blades 5 are arranged on the outer wall of the stirring rod 4, the stirring blades 5 are inclined, and the plurality of stirring blades 5 are staggered on the outer wall of the stirring rod 4; a stirring motor 6 is fixedly installed on the bottom surface of the stirring tank 1, and The output end of the stirring motor 6 is fixedly connected to the bottom end of the stirring rod 4; the feeding port 7 is opened on the top surface of the stirring tank 1; the screening plate 9 is arranged on the inner side of the connecting shell 2, and the outer wall of the screening plate 9 is fixedly installed with a collection frame 11, and the inner wall of the screening plate 9 is symmetrically provided with a connecting port 14 connected with the collection frame 11, and the screening holes on the screening plate 9 correspond to the position of the feeding port 7, and the width of the feeding box 3 is at least smaller than the diameter of the screening plate 9; the supporting assembly is arranged on the inner side of the feeding port 7; the transmission assembly is arranged between the supporting assembly and the bottom surface of the screening plate 9; the feeding assembly is arranged on the feeding box 3;

[0058] First, the Chinese medicinal material powder is slowly injected into the connecting shell 2 through the feeding box 3. This feeding process is precisely controlled by the feeding component, and the feeding speed can be adjusted according to the mixing requirements, which not only ensures the continuity of feeding, but also avoids the blockage or uneven mixing caused by too fast feeding. Once the Chinese medicinal materials enter the connecting shell 2, they will fall on the screening plate 9. Under the stable support of the supporting component and the precise drive of the transmission component, the screening plate 9 begins to vibrate regularly. This vibration process effectively promotes the dispersion and screening of the Chinese medicinal material powder, separates impurities and particles that do not meet the particle size requirements, and ensures the subsequent The quality of the raw materials in the mixing step, the pure Chinese medicinal material powder after screening, falls smoothly into the stirring tank 1 below through the feeding port 7 at the bottom of the connecting shell 2. Next, according to the formula requirements, the liquid required for mixing is accurately added to the stirring tank 1 through the liquid adding tube 13. This step not only requires accurate control of the amount of liquid added, but also ensures that the initial contact between the liquid and the Chinese medicinal material powder is uniform, laying the foundation for subsequent sufficient mixing. Finally, start the stirring motor 6. With the rotation of the stirring rod 4 and the stirring blade 5, the uniform mixing of the Chinese medicinal material and the liquid is promoted until a Chinese medicine preparation mixture that meets the standards is formed.

[0059] like Figure 1 , Figure 2As shown, the support assembly includes: a support plate 81, which is fixedly mounted on the inner side wall of the feed port 7 through a bracket; a one-way bearing 82, which is fixedly mounted on the inner side wall of the support plate 81; a movable plate 83, which is arranged on the inner side of the support plate 81, and the top surface of the movable plate 83 is fixedly connected to the bottom surface of the screening plate 9; a plurality of support springs 84, which are distributed in an annular array and fixedly mounted between the one-way bearing 82 and the movable plate 83; a clearance port 85, which is opened on the inner bottom wall of the movable plate 83, and the support plate 81, the one-way bearing 82, the movable plate 83 and the clearance port 85 are coaxially arranged;

[0060] In order to ensure that the screening plate 9 can perform vibration screening efficiently and stably, the movable disk 83 is designed to be tightly connected to the one-way bearing 82 through a supporting spring 84. This connection method allows the movable disk 83 to swing freely with the help of the elastic force of the supporting spring 84 when subjected to external force. This shaking can effectively transfer energy to the screening plate 9, causing it to generate high-frequency vibrations, thereby accelerating the screening process of the Chinese medicinal material powder and improving the screening efficiency. At the same time, the one-way bearing 82, with its unique locking function, limits the rotation direction of the movable disk 83, ensuring that the movable disk 83 can only rotate in a single direction, so as to subsequently drive the screening plate 9 to rotate to achieve centrifugal action.

[0061] like Figure 3 , Figure 4 As shown, the transmission assembly includes: a driving block 101, which is rotatably mounted on the inner bottom wall of the movable disk 83, and the driving block 101 is fixedly connected to the top of the stirring rod 4 through a connecting rod, and the driving block 101 is located at the position of the yielding opening 85; a guide frame 102, which is fixedly mounted on the side of the driving block 101; a one-way tooth plate 103, which is slidably mounted on the inner side wall of the guide frame 102; a second support spring 104, which is fixedly mounted between the one-way tooth plate 103 and the inner side wall of the guide frame 102; a plurality of one-way tooth grooves 105, which are distributed in an annular array and are opened on the inner side wall of the movable disk 83, and the one-way tooth plate 103 is meshed with the one-way tooth grooves 105;

[0062] When the stirring motor 6 is started and rotates forward, its power is accurately transmitted to the driving block 101 through the stirring rod 4, driving it to rotate synchronously. During this rotation process, the matching state between the one-way tooth plate 103 and the one-way tooth groove 105 is in a free state. At the same time, this direction happens to be the locking direction of the one-way bearing 82. Therefore, although the driving block 101 is continuously rotating, the one-way tooth plate 103 cannot directly drive the movable disk 83 to rotate synchronously; as the driving block 101 continues to rotate, the one-way tooth plate 103 begins to slide back and forth under the constraint of the guide frame 102. During this process, the one-way tooth plate 103 can perform a periodic pushing action on the movable disk 83. With the assistance of the supporting spring 84, this pushing action is converted into vibration of the movable disk 83, which is then transmitted to the screening plate 9 through the connecting mechanism, causing it to generate high-frequency vibration. This vibration can quickly remove large particles in the powder. The granular material is separated from the fine powder to ensure the uniformity and purity of the Chinese medicinal materials; when the screening process is completed, the stirring motor 6 immediately enters the reverse mode. At this time, the matching state of the one-way tooth plate 103 and the one-way tooth groove 105 undergoes a fundamental change and is transformed into a locked state. At the same time, this direction also becomes the allowed rotation direction of the one-way bearing 82. Therefore, when the driving block 101 rotates again, the one-way tooth plate 103 can drive the movable disk 83, the support spring 84 and the one-way bearing 82 to rotate synchronously as a whole. As the screening plate 9 rotates, the large particles that are screened are pushed to the outer edge of the screening plate 9 under the action of centrifugal force, and smoothly fall into the aggregate frame 11 below through the connecting port 14, which not only realizes the automatic collection of large particles, but also provides great convenience for subsequent further screening or processing, significantly improving the automation level and production efficiency of Chinese medicinal materials processing.

[0063] like Figure 1 , Figure 6 As shown, the feeding assembly includes: a discharge port 121, which is opened on the top surface of the feeding box 3; two feeding rollers 122, which are symmetrically mounted on the inner side wall of the feeding box 3; a feeding motor 123, which is fixedly mounted on the side wall of the feeding box 3, and the output end of the feeding motor 123 passes through the feeding box 3 and is fixedly connected to the end of one of the two feeding rollers 122; two connecting gears 124, which are symmetrically mounted on the end of the feeding box 3 away from the feeding motor 123, the two connecting gears 124 are meshed, and the two connecting gears 124 are respectively fixedly connected to the ends of the two feeding rollers 122 away from the feeding motor 123;

[0064] Once the Chinese medicinal materials are placed at the discharge port 121, the operator can start the feeding motor 123, and the two feeding rollers 122 are connected by a connecting gear 124, so that the two feeding rollers 122 can rotate synchronously in opposite directions, forming a feeding mode similar to "squeezing" and "releasing". When the Chinese medicinal materials fall into the narrow gap between the two feeding rollers 122, they will be subjected to slight pressure from the rollers on both sides. This pressure not only helps to evenly distribute the Chinese medicinal materials, but also effectively prevents large pieces of materials or impurities from passing through, thereby ensuring the quality of the Chinese medicinal materials entering the feeding box 3. More importantly, by accurately controlling the rotation speed of the feeding motor 123, the operator can easily adjust the rotation speed of the two feeding rollers 122, thereby realizing fine control of the feeding speed. This flexible feeding speed control mechanism enables the system to adapt to the feeding needs of Chinese medicinal materials of different types and sizes.
