Description

Technical Field

[0001] The invention relates to the field of medicinal material processing, and in particular to a medicinal material crushing and screening device for powder production. Background Art

[0002] In the powder production process, the crushing and screening of medicinal materials are crucial steps. Traditional powder production processes have numerous problems in this regard. Early methods of crushing medicinal materials relied primarily on manual hammering or simple mechanical grinding. This method was extremely inefficient and resulted in uneven particle size, making it difficult to meet the consistent particle size requirements of modern powder production. As production scaled up, this manual method was gradually phased out.

[0003] Later, some simple mechanical crushing equipment was introduced, but these devices have obvious limitations. When crushing sticky or hygroscopic medicinal materials, the powder is prone to agglomeration. Due to the lack of an effective breakup mechanism, the agglomerated medicinal material particles are difficult to pass through the subsequent screening process, resulting in the production of a large number of unqualified products, wasting medicinal material resources, and increasing production costs. Moreover, traditional screening devices rely solely on vibrating screens for screening. There is no auxiliary crushing structure on the top of the screen. The agglomerated medicinal material particles cannot be broken up in time during the screening process, resulting in low screening efficiency and difficult to ensure product quality.

[0004] Traditional equipment also has shortcomings in terms of power transmission and stability. For example, the power mechanisms used to drive the crushing or screening components are often complex and unstable, prone to failure, resulting in equipment downtime for maintenance and impacting production schedules. Furthermore, the lack of effective coordination between the various components of the equipment prevents flexible adjustments based on the characteristics of the medicinal materials, reducing the equipment's versatility and adaptability.

[0005] With the growing demand for powders and increasing demands for product quality, the development of an efficient, intelligent, and stable medicinal material crushing and screening device is urgently needed. This medicinal material crushing and screening device for powder production is designed to address these problems existing in traditional processes, aiming to improve the efficiency and quality of powder production, reduce production costs, and meet market demand for high-quality powder products. Summary of the Invention

[0013] Furthermore, the crushing mechanism also includes a positioning gear and several power gears. The positioning gear is arranged on the side of the center disk close to the adapter plate.

Several power gears are arranged along the circumferential direction of the positioning gear and are respectively rotatably connected to several tensioning seats.

[0014] Furthermore, the crushing mechanism also includes an air pipe, a rotary joint and several disc racks. The rotary joint is rotatably connected to the air chamber near the adapter plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First, this device is equipped with a power mechanism. For example, the first motor drives the screw to move the slide, and the second motor drives the center disk to rotate. This enables the steel wire to rotate in a circular direction on the upper end of the screen and move along the plane of the screen. This composite motion mode greatly improves the effect of breaking up agglomerated medicinal material powder. Compared with traditional single-motion pulverizing equipment, it can break up agglomerates more comprehensively and thoroughly, improve the efficiency and quality of medicinal material pulverization, provide higher-quality raw materials for subsequent screening steps, and help improve the quality stability of powder products.

[0019] Second, the gas regulation system in this device, consisting of an air pump, air chamber, Y-shaped tube, and buffer tube, can flexibly adjust the spacing between the steel wires based on the adhesion of medicinal materials. When medicinal material powder adheres to the steel wires, the gas pushes the tensioning seat to move, changing the spacing between the steel wires and allowing the medicinal materials wrapped between the steel wires to fall back onto the screen. This design effectively solves the problem of traditional equipment where the steel wires are easily adhered to by medicinal materials, affecting work efficiency. It improves the equipment's adaptability to medicinal materials with different characteristics, reduces the frequency of equipment cleaning, extends the equipment's continuous working time, and reduces labor maintenance costs.

[0020] Third: The positioning gear drives the power gear so that the steel wire can rotate on its own while rotating in a circular motion, breaking up the agglomerated medicinal material powder from multiple angles. This unique crushing method increases the contact area and contact method between the steel wire and the medicinal material. Compared with the traditional single rotation method of the steel wire, it can more efficiently break up the medicinal material agglomerates and further improve the crushing effect. This helps to crush the medicinal material more finely, meet the stricter requirements of powder production on the particle size of medicinal materials, and improve the quality and market competitiveness of the product.

[0032] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] refer to Figures 1 to 9 A medicinal material crushing and screening device for powder production includes a vibrating screen 1 and a positioning frame 2 arranged on the upper end of the vibrating screen 1, and further includes:

[0034] Two movable plates 3 are arranged below the positioning frame 2, and each movable plate 3 is slidably connected to the positioning frame 2 through two guide rods 4. Two electric push rods 5 are provided on one side of the positioning frame 2 close to each movable plate 3. The fixed end of the electric push rod 5 is fixedly connected to the positioning frame 2, and the movable end of the electric push rod 5 is fixedly connected to the movable plate 3. A power mechanism 6 is provided on each movable plate 3. The power mechanism 6 includes a slide 8, a center disk 27, an adapter plate 13 and two side plates 7. The two side plates 7 are respectively fixedly connected to the two ends of the lower side of the movable plate 3, and the slide 8 is fixedly connected to the lower end of the movable plate 3. The sliding connection is that the center disk 27 is rotatably connected to the side of the slide 8 close to the screen of the vibrating screen 1. A plurality of steel wires 30 are arranged in an array at equal angles along the circumferential direction on the side where the two center disks 27 are close to each other. The adapter plate 13 is fixedly connected to the slide 8. A crushing mechanism 29 is provided on the center disk 27. The crushing mechanism 29 includes a plurality of tensioning seats 32, a plurality of rope seats 31, two air chambers 40, a plurality of Y-shaped tubes 41 and a plurality of buffer tubes 43. The rope seat 31 is fixedly connected to the steel wire 30. Tensioning seats 32 (such as Figure 9As shown), the tensioning seat 32 is rotatably connected to the rope seat 31, the two air chambers 40 are interconnected and fixedly connected to the center disk 27 coaxially, and the adapter plate 13 is fixedly connected to an air pump 34 for supplying air to the air chamber 40. Each air chamber 40 is slidingly arranged in an array at equal intervals along the circumferential direction with a number of Y-shaped tubes 41 connected thereto, the single end of the Y-shaped tube 41 is slidingly connected to the air chamber 40, and the two ends of the tensioning seat 32 are respectively fixedly connected to the double-headed ends of the corresponding Y-shaped tube 41. The buffer tube 43 is arranged on the side of the tensioning seat 32 away from the center of the center disk 27, and the upper end of the Y-shaped tube 41 is slidingly sleeved with the two buffer tubes 43 respectively.

[0035] When the device is in operation, when the medicinal materials fall onto the upper part of the screen of the vibrating screen 1, the screen of the vibrating screen 1 will screen the medicinal materials. However, in this process, some sticky or hygroscopic medicinal powders are prone to agglomeration during the screening process, forming larger particles that are difficult to pass through the sieve holes. Therefore, a number of steel wires 30 arranged at the upper part of the screen will break these particles. The specific breaking process is as follows: two electric push rods 5 push the moving plate 3 downward so that the steel wires 30 are close to the screen, and then the power mechanism 6 starts and drives the center disk 27 to rotate. When the center disk 27 rotates, the steel wires 30 will rotate along the center direction of the center disk 27. At the same time, the slide 8 will move along the long side direction of the moving plate 3. The steel wires 30 can break the medicinal powder agglomerated at the upper part of the screen of the vibrating screen 1 during the rotation process.

[0036] During this process, sticky or hygroscopic medicinal powders tend to adhere between the steel wires 30, gradually accumulating to form larger lumps as the steel wires 30 move. The air pump 34 supplies and deflates the Y-shaped tubes 41 through the air chamber 40, allowing the tensioning seat 32 to move the steel wires 30 via the rope seat 31, thereby changing the relative distance between adjacent steel wires 30. This ensures that medicinal materials that have passed through the gap between adjacent steel wires 30 and are trapped by the steel wires 30 and cannot fall off can fall back onto the screen of the vibrating screen 1 after the steel wires 30 move.

[0037] In order to limit the movement of the slide 8, the following features are specifically provided:

[0038] The power mechanism 6 also includes a slider 14 and a guide rail 15. The slider 14 is fixedly connected to the adapter plate 13. The two ends of the guide rail 15 are respectively fixedly connected to the two side plates 7. The slider 14 is slidably connected to the guide rail 15. When the slider 14 slides along the guide rail 15, the guide rail 15 and the slider 14 cooperate to provide a stable guiding effect for the movement of the slide 8. The slider 14 slides on the guide rail 15, limiting the movement of the slide 8 to only along the direction determined by the guide rail 15, preventing the slide 8 from deflecting or shaking during movement, thereby ensuring the accuracy and stability of the movement of the slide 8, allowing the steel wire 30 to accurately move along the preset trajectory of the screen of the vibrating screen 1, and improving the effect and efficiency of breaking up the agglomerates on the screen.

[0039] In order to realize the movement of the slide 8 so that the plurality of steel wires 30 can move along the upper end of the screen of the vibrating screen 1 so as to break up all the agglomerates on the screen, the following features are specifically provided:

[0040] The power mechanism 6 also includes a first motor 9, a screw 10, a screw sleeve 11 and a screw seat 12. The screw seat 12 is fixedly connected to the slide 8, the screw sleeve 11 is fixedly connected to the screw seat 12, the two ends of the screw 10 are respectively rotatably connected to the two side plates 7, the screw 10 is threadedly connected to the screw sleeve 11, the first motor 9 is fixedly connected to one side plate 7 and the output end is fixedly connected to the coaxial line of the screw 10. When the first motor 9 rotates, the first motor 9 drives the screw sleeve 11 to move through the screw 10, and the screw sleeve 11 drives the slide 8 to move through the screw seat 12. At the same time, the operator can flexibly adjust the moving direction of the slide 8 by controlling the forward and reverse rotation of the first motor 9, so that a number of steel wires 30 can be fully moved along the upper end of the screen of the vibrating screen 1, ensuring that all agglomerates on the screen can be effectively broken up, thereby improving the comprehensiveness and thoroughness of the medicinal material crushing and screening.

[0041] In order to drive the center disk 27 to rotate when the slide 8 moves, and thus realize that when the plurality of steel wires 30 move along the upper end of the screen of the vibrating screen 1, the plurality of steel wires 30 can rotate along the circumferential direction of the center disk 27, the following features are specifically provided:

[0042] The power mechanism 6 also includes a second motor 16, a power shaft 17, a sleeve 18, a first bevel gear 19, a bevel gear rack 20, a second bevel gear 21, a first gear 22, a first pulley 23, a second pulley 24, a second gear 25 and a third gear 26. The second motor 16 is fixedly connected to a side plate 7, and the two ends of the power shaft 17 are respectively rotatably connected to the two side plates 7. The bevel gear rack 20 is fixedly connected to the slide 8. The first bevel gear 19 is rotatably connected to the bevel gear rack 20 and is coaxially arranged with the power shaft 17. The sleeve 18 is coaxially fixed to the first bevel gear 19. The sleeve 18 is key-connected to the power shaft 17. The second bevel gear 21 is rotatably connected to the bevel gear rack 20 and meshes with the first bevel gear 19. The first gear 22 is rotatably connected to the slide 8 and is coaxially fixedly connected to the second bevel gear 21. The first pulley 23 is coaxially fixedly connected to the first gear 22. The second pulley 24 is rotatably arranged below the first pulley 23 and is connected to the first pulley 23 through a belt drive. The second gear 25 is coaxially fixedly connected to the second pulley 24. The third gear 26 is coaxially fixedly connected to the center disk 27 and meshes with the second gear 25. When the second motor 16 is started, the second motor 16 will drive the power shaft 17 to rotate. The power shaft 17 will drive the first bevel gear 19 to rotate through the sleeve 18. The first bevel gear 19 will drive the first gear 22 to rotate through the second bevel gear 21. The first gear 22 drives the second pulley 24 to rotate through the first pulley 23. The second pulley 24 drives the third gear 26 to rotate through the second gear 25. During this process, the first gear 22 is used to ensure that the first pulley 23 and the second pulley 24 are in parallel positions, thereby preventing the belt from being twisted due to uneven positions of the first pulley 23 and the second pulley 24 .

[0043] In order to facilitate the plurality of steel wires 30 to rotate on their own when rotating in the circumferential direction along the center disk 27, the following features are specifically provided:

[0044] The crushing mechanism 29 also includes a positioning gear 38 and several power gears 39. The positioning gear 38 is positioned on the side of the center disk 27 near the adapter plate 13. The positioning gear 38 is fixedly connected to the slide 8 via a gasket. Several power gears 39 are arranged circumferentially around the positioning gear 38 and are rotatably connected to the tensioning seats 32. The power gears 39 are coaxially fixedly connected to the rope seat 31 and mesh with the positioning gear 38. When the center disk 27 rotates, the positioning gear 38 rotates accordingly. Because the power gears 39 are arranged circumferentially around the positioning gear 38 and are rotatably connected to the tensioning seats 32, the power gears 39 are coaxially fixedly connected to the rope seat 31, and mesh with the positioning gear 38, when the center disk 27 rotates, the positioning gear 38 remains stationary, causing the power gears 39 to roll circumferentially around the positioning gear 38, thereby causing the power gears 39 to rotate. The rotation of the power gear 39 causes the rope holder 31 and the steel wire 30 connected thereto to rotate in a circular direction along the center disk 27 while also rotating on their own. The rotation of the steel wire 30 can break up agglomerated medicinal powder from different angles, further improving the breaking efficiency and effectiveness, and helping to more thoroughly break up sticky or hygroscopic medicinal powder agglomerates.

[0045] In order to prevent the interruption of gas transmission between the air chamber 40 and the air pump 34 when the center disk 27 rotates, the following features are specifically provided:

[0046] The crushing mechanism 29 further includes an air pipe 35, a rotary joint 37 and a plurality of disc racks 36. The rotary joint 37 is rotatably connected to the air chamber 40 near the adapter plate 13. The plurality of disc racks 36 are arranged in an array with equal angles along the circumference of the rotary joint 37 (e.g., Figure 6 As shown in the figure, one end of the disc rack 36 is fixedly connected to the rotary joint 37, and the other end is fixedly connected to the adapter plate 13. The air pipe 35 is coaxially arranged with the rotary joint 37. One end of the air pipe 35 is fixedly connected to the rotary joint 37, and the other end is connected to the output end of the air pump 34. During the rotation of the center disc 27, the air chamber 40 will also rotate accordingly. The air pipe 35 is rotatably connected to the air chamber 40 near the adapter plate 13 through the rotary joint 37. The rotary joint 37 is fixedly connected to the adapter plate 13 through several disc racks 36. One end of the air pipe 35 is fixedly connected to the rotary joint 37 and connected to the air chamber 40, and the other end is connected to the output end of the air pump 34. This structural design ensures that even if the air chamber 40 is rotating, the connection between the air pipe 35 and the air chamber 40 remains stable, and the air pump 34 can continue to supply air to the air chamber 40 without interruption of gas transmission. The stable air supply ensures the normal air supply and air release operation of the air chamber 40 to the Y-shaped tube 41, so that the steel wires 30 can adjust the spacing according to a preset method to meet the processing requirements of the medicinal material powder agglomerates.

[0047] In order to avoid the displacement of the rope seats 31, the following features are also provided:

[0048] The crushing mechanism 29 also includes a plurality of connecting tubes 33. The center disk 27 is formed with a plurality of limiting holes 28 arranged at equal angles along the circumference. The connecting tubes 33 are respectively sleeved over the exterior of the rope seats 31. The rope seats 31 are rotatably connected to the connecting tubes 33, while the connecting tubes 33 are slidably connected to the limiting holes 28. The ends of the connecting tubes 33 are respectively fixedly connected to the corresponding tensioning seats 32. When the air chamber 40 supplies or releases air to the Y-shaped tube 41, causing the tensioning seat 32 to move the steel wire 30 through the rope seat 31, the center disk 27 has a plurality of limiting holes 28 arranged at equal angles along the circumference. The connecting tubes 33 are respectively sleeved over the exterior of the rope seats 31. The rope seats 31 are rotatably connected to the connecting tubes 33, while the connecting tubes 33 are slidably connected to the limiting holes 28. The ends of the connecting tubes 33 are respectively fixedly connected to the corresponding tensioning seats 32. Therefore, when the tensioning seat 32 moves, the connecting tube 33 can drive the rope seat 31 to slide in the limiting hole 28, thereby avoiding the displacement of several rope seats 31. This design ensures the stability and accuracy of the rope seat 31 during movement, allowing the adjustment of the spacing of the steel wires 30 to be carried out smoothly.

[0049] In order to facilitate when the air pump 34 supplies air to the two air chambers 40, since the Y-shaped tube 41 guides the gas into the buffer tube 43, the increase in gas in the buffer tube 43 can push the tensioning seat 32 to move, and the tensioning seat 32 can drive the rope seat 31 to move toward the center of the center disk 27 through the connecting tube 33, thereby reducing the distance between the two adjacent steel wires 30 and increasing the contact frequency between the steel wires 30 and the agglomerated Chinese medicine. After the air pump 34 deflates the two air chambers 40, since the gas in the buffer tube 43 is reduced, the Y-shaped tube 41 tensioning seat 32 can drive the rope seat 31 to move away from the center of the center disk 27 through the connecting tube 33, thereby increasing the distance between the two adjacent steel wires 30. Specifically, the following features are also provided:

[0050] The crushing mechanism 29 also includes a plurality of tube seats 42, a plurality of buffer plates 44, and a plurality of buffer springs 45. The plurality of tube seats 42 are arranged in an array at equal angles along the circumference of the center disk 27. The tube seats 42 are located on the side of the stop hole 28 away from the center of the center disk 27 and are fixedly connected to the center disk 27. The buffer plate 44 is coaxially fixedly connected to the outside of the buffer tube 43. The buffer spring 45 is sleeved on the outside of the Y-shaped tube 41. The upper end of the buffer spring 45 is fixedly connected to the buffer plate 44, and the lower end is fixedly connected to the tensioning seat 32. When the air pump 34 supplies air to the two air chambers 40, the air enters the buffer tube 43 through the Y-shaped tube 41. The increased air in the buffer tube 43 pushes the buffer plate 44, which in turn stretches the buffer spring 45, thereby moving the tensioning seat 32. The tensioning seat 32, through the connecting tube 33, drives the rope seat 31 toward the center of the center disk 27, reducing the distance between adjacent steel wires 30. This increases the frequency of contact between the steel wires 30 and the agglomerated Chinese medicine, enhancing the ability to break up the agglomerates. When the air pump 34 deflates the two air chambers 40, the gas in the buffer tube 43 decreases, the buffer spring 45 contracts, and pulls on the buffer plate 44, causing the tensioning seat 32, through the connecting tube 33, to drive the rope seat 31 away from the center of the center disk 27, increasing the distance between adjacent steel wires 30. The arrangement of multiple tube seats 42 provides a foundation for the installation of the buffer tube 43 and buffer spring 45, ensuring the stability and effectiveness of the entire structure.

[0051] The working principle of this device is that when the medicinal materials are placed on the upper end of the screen of the vibrating screen 1, the vibrating screen 1 starts working first, and uses the vibration of the screen to perform preliminary screening of the medicinal materials. The medicinal material powder that meets the sieve hole size will fall through the screen, while larger particles or agglomerated medicinal materials will remain on the upper end of the screen.

[0052] At this time, in order to solve the problem of easy agglomeration of sticky or hygroscopic medicinal powder, the device starts the crushing function. The two electric push rods 5 push the movable plate 3 downward, so that the power mechanism 6 set on the movable plate 3 is close to the screen, which is specifically manifested as a number of steel wires 30 approaching the screen. Then, the first motor 9 in the power mechanism 6 starts and drives the screw 10 to rotate, so that the slide 8 moves along the long side direction of the movable plate 3. At the same time, the second motor 16 starts and finally drives the center disk 27 to rotate, so that the steel wires 30 can rotate along the center direction of the center disk 27 while also moving on the upper end of the screen with the slide 8 to break up the agglomerated medicinal powder.

[0053] During the operation of the steel wires 30, because medicinal material powder tends to clump and stick together between the wires 30, the air pump 34 activates. The air pump 34 supplies air to the air chamber 40 through the air pipe 35 and rotary joint 37. The air chamber 40 distributes the air to a number of Y-shaped tubes 41. Once the air enters the Y-shaped tubes 41, it pushes the buffer tube 43, which in turn pushes the tensioning seat 32. The tensioning seat 32, through the rope seat 31, moves the steel wires 30, changing the relative distance between adjacent steel wires 30. This ensures that medicinal materials trapped by the steel wires 30, preventing them from falling, can fall back onto the screen of the vibrating screen 1 after the wires 30 move.

[0054] During this process, the slider 14 in the power mechanism 6 slides on the guide rail 15, ensuring the stability of the movement of the slide 8. The positioning gear 38 drives the power gear 39, allowing the steel wire 30 to rotate while rotating in a circular motion, enhancing the crushing effect. The arrangement of the air pipe 35 and the rotary joint 37 ensures uninterrupted gas transmission during the rotation of the air chamber 40. The connecting pipe 33 avoids the displacement of the rope seat 31, ensuring smooth adjustment of the spacing between the steel wires 30. The cooperation of the pipe seat 42, the buffer plate 44, and the buffer spring 45 precisely controls the change in the spacing between the steel wires 30, improving the processing capacity of agglomerated medicinal materials. Through the coordinated operation of various components, the entire device efficiently completes the tasks of crushing and screening medicinal materials, improving the quality and efficiency of powder production.
