Description

Technical Field

[0001] The present invention relates to the field of medicinal material processing, and more specifically, to a medicinal material pulverizing and screening device for powder production. Background Art

[0002] In the process of powder production, the pulverization and screening of medicinal materials are crucial steps. There are many problems in the traditional powder production process in this regard. In the early days, the pulverization of medicinal materials mainly relied on manual pounding or simple mechanical grinding. This method was extremely inefficient, and the particle size of the pulverized medicinal materials was uneven, making it difficult to meet the requirements of modern powder production for the consistency of the particle size of medicinal materials. With the expansion of production scale, this manual operation method was gradually phased out. Subsequently, some simple mechanical pulverization equipment was introduced, but these devices had obvious limitations. When pulverizing sticky or hygroscopic medicinal materials, the powder was prone to agglomeration. Due to the lack of an effective dispersion mechanism, the agglomerated medicinal material particles were 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, the traditional screening device only relied on a vibrating screen for screening, and there was no auxiliary pulverization structure at the upper end of the screen mesh. The agglomerated medicinal material particles could not be broken in time during the screening process, making the screening efficiency low and the product quality difficult to guarantee. In terms of power transmission and equipment stability, traditional equipment also had deficiencies. For example, the power mechanism used to drive the pulverization component or the screening component was often complex and unstable in structure, prone to failures, resulting in equipment downtime for maintenance and affecting the production progress. At the same time, there was a lack of an effective collaborative working mechanism between the various components of the equipment, and it was impossible to make flexible adjustments according to the characteristics of the medicinal materials, reducing the versatility and adaptability of the equipment.

[0003] With the continuous growth of the market demand for powders and the increasing requirements for product quality, it is urgent to develop an efficient, intelligent, and stable medicinal material pulverizing and screening device. The medicinal material pulverizing and screening device for powder production of the present invention is designed to solve these problems existing in the traditional process, aiming to improve the efficiency and quality of powder production, reduce production costs, and meet the market demand for high-quality powder products.

[0009] Further, the crushing mechanism further includes a positioning gear and a plurality of power gears. The positioning gear is arranged on one side of the central disk close to the adapter plate. The positioning gear is fixedly connected to the sliding table through a gasket.

This compound movement mode greatly improves the crushing effect on the agglomerated medicinal material powder. Compared with the traditional crushing equipment with a single movement mode, it can disperse the agglomerates more comprehensively and thoroughly, improve the efficiency and quality of medicinal material crushing, provide higher-quality raw materials for the subsequent screening link, and help improve the quality stability of the powder product; Second: The gas regulation system composed of the air pump, the air chamber, the Y-shaped pipe, the buffer pipe, etc. in the device can flexibly adjust the distance between the steel wires according to the adhesion situation of the medicinal materials. When the medicinal material powder adheres between the steel wires, the air is used to push the tensioning seat to move, changing the distance between the steel wires, so that the medicinal materials wrapped between the steel wires can fall back to the sieve mesh. This design effectively solves the problem that the steel wires in the traditional equipment are easily adhered by the medicinal materials and affect the working efficiency, improves the adaptability of the equipment to medicinal materials with different characteristics, reduces the cleaning frequency of the equipment, prolongs the continuous working time of the equipment, and reduces the manual maintenance cost; Thirdly: The design that the positioning gear drives the power gear to enable the steel wire to rotate on its own while rotating in a circle breaks up the agglomerated medicinal materials powder from multiple angles. This unique pulverizing method increases the contact area and contact method between the steel wire and the medicinal materials. Compared with the single rotation method of traditional steel wires, it can more efficiently disperse the agglomerated medicinal materials, further improving the pulverizing effect. This helps to pulverize the medicinal materials more finely, meet the more stringent requirements for the particle size of medicinal materials in powder production, and enhance the quality and market competitiveness of the product.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Reference Figures 1 to 9 , a device for pulverizing and screening medicinal materials for powder production, including a vibrating screen 1 and a positioning frame 2 provided at the upper end of the vibrating screen 1, and further including: Two moving plates 3 provided below the positioning frame 2, each moving plate 3 is respectively slidably connected to the positioning frame 2 through two guide rods 4. On one side of the positioning frame 2 close to each moving plate 3, two electric push rods 5 are provided. 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 moving plate 3. A power mechanism 6 is provided on each moving plate 3. The power mechanism 6 includes a sliding table 8, a central disk 27, a transfer 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 moving plate 3. The sliding table 8 is slidably connected to the lower end of the moving plate 3. The central disk 27 is rotatably connected to one side of the sliding table 8 close to the screen of the vibrating screen 1. A number of steel wires 30 are arranged at equal angular intervals along the circumferential direction on the side of the two central disks 27 close to each other. The transfer plate 13 is fixedly connected to the sliding table 8. A crushing mechanism 29 is provided on the central disk 27. The crushing mechanism 29 includes a number of tensioning seats 32, a number of rope seats 31, two air chambers 40, a number of Y-shaped pipes 41, and a number of buffer pipes 43. The rope seats 31 are fixedly connected to the steel wires 30. Tensioning seats 32 are respectively provided at both ends of the rope seats 31 (as Figure 9 shown), the tensioning seats 32 are rotatably connected to the rope seats 31. The two air chambers 40 communicate with each other and are coaxially fixedly connected to the central disk 27. An air pump 34 for supplying air to the air chambers 40 is fixedly connected to the transfer plate 13. A number of Y-shaped pipes 41 communicating with it are slidably arranged at equal intervals along the circumferential direction in each air chamber 40. The single-head end of the Y-shaped pipe 41 is slidably connected to the air chamber 40. Both ends of the tensioning seat 32 are fixedly connected to the double-head ends of the corresponding Y-shaped pipes 41. The buffer pipes 43 are provided on the side of the tensioning seat 32 away from the center of the central disk 27. The upper ends of the Y-shaped pipes 41 are respectively slidably sleeved with the two buffer pipes 43.

[0018] When the device is operating, when the medicinal materials fall onto the upper end of the screen of the vibrating screen 1, the screen of the vibrating screen 1 will screen the medicinal materials. However, during this process, some medicinal material powders with viscosity or hygroscopicity are prone to agglomeration during the screening process, forming larger particles and being difficult to pass through the sieve holes. Therefore, a number of steel wires 30 provided at the upper end of the screen will break these particles. The specific breaking process is as follows: The two electric push rods 5 push the moving plate 3 downward so that a number of steel wires 30 approach the screen. Subsequently, the power mechanism 6 is started and drives the central disk 27 to rotate. When the central disk 27 rotates, a number of steel wires 30 will rotate along the direction of the center of the central disk 27. At the same time, the sliding table 8 will move along the long side direction of the moving plate 3. A number of steel wires 30 can break the agglomerated medicinal material powders at the upper end of the screen of the vibrating screen 1 during the rotation process.

[0019] In the above process, sticky or hygroscopic medicinal powder is easy to adhere between the steel wires 30, and gradually accumulates to form larger blocks as the steel wires 30 move. The air pump 34 supplies air and releases air to the Y-shaped tubes 41 through the air chamber 40, so that the tensioning seat 32 drives the steel wires 30 to move through the rope seat 31, thereby changing the relative distance between two adjacent steel wires 30, ensuring that the medicinal materials that pass through the gap between two adjacent steel wires 30 and are wrapped by the steel wires 30 and cannot fall can fall back onto the screen of the vibrating screen 1 after the steel wires 30 move.

[0020] In order to limit the movement of the slide 8, the following features are also specifically provided: 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 movement of the slide 8 in cooperation with the guide rail 15 and the slider 14 provides a stable guiding effect. The slider 14 slides on the guide rail 15, limiting the slide 8 to move only in the direction determined by the guide rail 15, avoiding the slide 8 from deflecting or shaking during the movement, thereby ensuring the accuracy and stability of the movement of the slide 8, so that the steel wire 30 can accurately move along the preset track of the screen of the vibrating screen 1, improving the effect and efficiency of breaking up the agglomerates on the screen.

[0021] 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 also specifically provided: 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 crushing and screening of medicinal materials.

[0022] In order to drive the center disk 27 to rotate when the slide 8 moves, so 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: The power mechanism 6 further includes a second motor 16, a power shaft 17, a bushing 18, a first bevel gear 19, a bevel gear bracket 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. Both ends of the power shaft 17 are rotatably connected to the two side plates 7. The bevel gear bracket 20 is fixedly connected to the slide 8. The first bevel gear 19 is rotatably connected to the bevel gear bracket 20 and is coaxially arranged with the power shaft 17. The bushing 18 is coaxially and fixedly connected to the first bevel gear 19. The bushing 18 is key-connected to the power shaft 17. The second bevel gear 21 is rotatably connected to the bevel gear bracket 20 and meshes with the first bevel gear 19. The first gear 22 is rotatably connected to the slide 8 and is coaxially and fixedly connected to the second bevel gear 21. The first pulley 23 is coaxially and 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 by belt drive. The second gear 25 is coaxially and fixedly connected to the second pulley 24. The third gear 26 is coaxially and fixedly connected to the central disk 27 and meshes with the second gear 25. When the second motor 16 is started, the second motor 16 drives the power shaft 17 to rotate. The power shaft 17 drives the first bevel gear 19 to rotate through the bushing 18. The first bevel gear 19 drives 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 a parallel position, preventing the belt from twisting due to the uneven position of the first pulley 23 and the second pulley 24.

[0023] In order to facilitate the rotation of a plurality of steel wires 30 in the circumferential direction along the central disk 27 and enable the plurality of steel wires 30 to rotate about their own axes, the following features are further provided: The crushing mechanism 29 further includes a positioning gear 38 and a plurality of driving gears 39. The positioning gear 38 is arranged on one side of the central disk 27 close to the adapter plate 13. The positioning gear 38 is fixedly connected to the sliding table 8 through a gasket. The plurality of driving gears 39 are arranged along the circumferential direction of the positioning gear 38 and are respectively rotatably connected to a plurality of tension seats 32. The driving gear 39 is coaxially fixedly connected to the rope seat 31, and the driving gear 39 meshes with the positioning gear 38. When the central disk 27 rotates, the positioning gear 38 rotates accordingly. Since the plurality of driving gears 39 are arranged along the circumferential direction of the positioning gear 38, and are respectively rotatably connected to a plurality of tension seats 32, the driving gear 39 is coaxially fixedly connected to the rope seat 31, and the driving gear 39 meshes with the positioning gear 38, when the central disk 27 rotates, because the positioning gear 38 remains stationary, the plurality of driving gears 39 will roll along the circumferential direction of the positioning gear 38, and at this time the driving gear 39 will rotate. The rotation of the driving gear 39 enables the rope seat 31 and the steel wire 30 connected thereto to rotate circumferentially along the central disk 27 while also being able to rotate on its own axis. The self-rotation of the steel wire 30 can break up the agglomerated medicinal material powder from different angles, further improving the crushing efficiency and effect, and helping to more thoroughly disperse the viscous or hygroscopic medicinal material powder agglomerates.

[0024] In order to prevent the interruption of gas transmission between the air chamber 40 and the air pump 34 when the central disk 27 rotates, the following features are specifically set: The crushing mechanism 29 further includes an air pipe 35, a rotary joint 37 and a plurality of disk frames 36. The rotary joint 37 is rotatably connected to the air chamber 40 close to the adapter plate 13. The plurality of disk frames 36 are arranged at equal angles in an array along the circumferential direction of the rotary joint 37 (as Figure 6 shown). One end of the disk frame 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 communicated with the output end of the air pump 34. During the rotation of the central disk 27, the air chamber 40 will also rotate accordingly. The air pipe 35 is rotatably connected to the air chamber 40 close to the adapter plate 13 through the rotary joint 37. The rotary joint 37 is fixedly connected to the adapter plate 13 through a plurality of disk frames 36. One end of the air pipe 35 is fixedly connected to the rotary joint 37 and is communicated with the air chamber 40, and the other end is communicated with the output end of the air pump 34. Such a structural design ensures that even if the air chamber 40 rotates, the connection between the air pipe 35 and the air chamber 40 remains stable, and the air pump 34 can continuously supply air to the air chamber 40 without gas transmission interruption. The stable air supply ensures the normal air supply and air release operations of the air chamber 40 to the Y-shaped pipe 41, enabling the steel wire 30 to adjust the spacing according to the preset manner to meet the processing requirements of the medicinal material powder agglomerates.

[0025] In order to avoid the displacement of a plurality of rope seats 31, the following features are specifically set: The crushing mechanism 29 further includes a number of connecting pipes 33. The central disk 27 is formed with a number of limiting holes 28 arrayed at equal angles along the circumferential direction. The number of connecting pipes 33 are respectively sleeved outside the number of rope seats 31. The rope seats 31 are rotatably connected to the connecting pipes 33, and the connecting pipes 33 are slidably connected to the limiting holes 28. Both ends of the connecting pipes 33 are fixedly connected to the corresponding tensioning seats 32. When the air chamber 40 supplies or discharges air to the Y-shaped pipe 41, causing the tensioning seat 32 to drive the steel wire 30 to move through the rope seat 31, since the central disk 27 is formed with a number of limiting holes 28 arrayed at equal angles along the circumferential direction, the number of connecting pipes 33 are respectively sleeved outside the number of rope seats 31, the rope seats 31 are rotatably connected to the connecting pipes 33, the connecting pipes 33 are slidably connected to the limiting holes 28, and both ends of the connecting pipes 33 are fixedly connected to the corresponding tensioning seats 32. Therefore, when the tensioning seat 32 moves, it can drive the rope seat 31 to slide in the limiting hole 28 through the connecting pipe 33, realizing the avoidance of the displacement of the number of rope seats 31. This design ensures the stability and accuracy of the rope seat 31 during the movement process, enabling the adjustment of the distance between the steel wires 30 to proceed smoothly.

[0026] To facilitate the supply of air to the two air chambers 40 by the air pump 34, since the Y-shaped pipe 41 diverts the gas into the buffer pipe 43, after the gas in the buffer pipe 43 increases, it can push the tensioning seat 32 to move. The tensioning seat 32 can drive the rope seat 31 to move towards the direction close to the center of the central disk 27 through the connecting pipe 33, thereby reducing the distance between two adjacent steel wires 30 and increasing the contact frequency between the steel wires 30 and the agglomerated traditional Chinese medicine. After the air pump 34 discharges air from the two air chambers 40, since the gas in the buffer pipe 43 decreases, the Y-shaped pipe 41 and the tensioning seat 32 can drive the rope seat 31 to move away from the center of the central disk 27 through the connecting pipe 33, thereby increasing the distance between two adjacent steel wires 30. Specifically, the following features are further provided: The crushing mechanism 29 further includes a plurality of pipe seats 42, a plurality of buffer plates 44 and a plurality of buffer tension springs 45. The plurality of pipe seats 42 are respectively arranged at equal angular intervals along the circumferential direction of the central disc 27. The pipe seats 42 are arranged on the side of the limiting hole 28 away from the center of the central disc 27 and are fixedly connected to the central disc 27. A buffer plate 44 is coaxially and fixedly connected to the outside of the buffer pipe 43. The buffer tension spring 45 is sleeved on the outside of the Y-shaped pipe 41. The upper end of the buffer tension 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 gas enters the buffer pipe 43 through the Y-shaped pipe 41. The increase in the gas in the buffer pipe 43 pushes the buffer plate 44, and the buffer plate 44 drives the buffer tension spring 45 to stretch, thereby pushing the tensioning seat 32 to move. The tensioning seat 32 drives the wire seat 31 to move towards the center of the central disc 27 through the connecting pipe 33, reducing the distance between two adjacent steel wires 30, increasing the contact frequency between the steel wires 30 and the agglomerated traditional Chinese medicine, and enhancing the effect of breaking up the agglomerates. When the air pump 34 deflates the two air chambers 40, the gas in the buffer pipe 43 decreases, the buffer tension spring 45 contracts, pulling the buffer plate 44, so that the tensioning seat 32 drives the wire seat 31 to move away from the center of the central disc 27 through the connecting pipe 33, increasing the distance between two adjacent steel wires 30. The arrangement of the plurality of pipe seats 42 provides an installation basis for the buffer pipe 43 and the buffer tension spring 45, ensuring the stability and effectiveness of the whole structure.

[0027] The working principle of this device is that when the medicinal materials are placed on the upper end of the vibrating screen 1, the vibrating screen 1 starts to work first, and the medicinal materials are preliminarily screened by using the vibration of the screen. The medicinal material powder that meets the sieve hole size will fall through the screen, while the larger particles or agglomerated medicinal materials remain on the upper end of the screen. At this time, in order to solve the problem that the medicinal material powder with viscosity or hygroscopicity is prone to agglomeration, the device starts to activate the crushing function. The two electric push rods 5 push the moving plate 3 downward, so that the power mechanism 6 arranged on the moving plate 3 approaches the screen, specifically, a plurality of steel wires 30 approach the screen. Then, the first motor 9 in the power mechanism 6 starts and drives the screw rod 10 to rotate, so that the sliding table 8 moves along the long side direction of the moving plate 3. At the same time, the second motor 16 starts and finally drives the central disc 27 to rotate, so that a plurality of steel wires 30 can rotate along the direction of the center of the central disc 27 and move on the upper end of the screen along with the sliding table 8 at the same time, breaking up the agglomerated medicinal material powder.

[0028] During the operation of the steel wires 30, since the medicinal material powder is prone to adhesion between the steel wires 30 to form lumps, the air pump 34 starts to work. The air pump 34 supplies air to the air chamber 40 through the air pipe 35 and the rotary joint 37. The air chamber 40 distributes the gas to a number of Y-shaped pipes 41. When the gas enters the Y-shaped pipe 41, it pushes the buffer pipe 43, and then pushes the tensioning seat 32. The tensioning seat 32 drives the steel wire 30 to move through the rope seat 31, changing the relative distance between two adjacent steel wires 30. This can ensure that the medicinal materials wrapped by the steel wires 30 and unable to fall can fall back to the screen of the vibrating screen 1 after the movement of the steel wires 30. During this process, the slider 14 in the power mechanism 6 slides on the guide rail 15 to ensure the stability of the movement of the sliding table 8; the positioning gear 38 drives the power gear 39, enabling the steel wire 30 to rotate on its own while rotating in a circle, enhancing the crushing effect; the settings of the air pipe 35 and the rotary joint 37 ensure that the gas transmission is not interrupted when the air chamber 40 rotates; the connecting pipe 33 avoids the displacement of the rope seat 31 to ensure the smooth adjustment of the distance 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 distance between the steel wires 30, improving the processing capacity for agglomerated medicinal materials. The entire device efficiently completes the crushing and screening tasks of the medicinal materials through the coordinated work of each component, improving the quality and efficiency of the powder production.

[0029] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
