Description

Technical Field

[0001] This invention relates to the field of medicinal material grinding, and in particular to a rotary grinding device for processing traditional Chinese medicine materials. Background Technology

[0002] In the field of traditional Chinese medicine processing, grinding dry medicinal materials into fine powders can, on the one hand, increase the surface area of ​​the materials, promote the release of active ingredients, and improve drug absorption efficiency and efficacy; on the other hand, it can make the materials easier to be made into various dosage forms such as tablets, powders, and ointments to meet the needs of different medication scenarios.

[0003] However, existing Chinese medicine grinding devices generate a large amount of heat during the grinding process due to the continuous friction and impact between the grinding components and the medicinal materials. Most devices lack a targeted and efficient cooling structure, relying solely on natural heat dissipation, leading to a rapid increase in the temperature inside the grinding chamber. For medicinal materials containing volatile components, such as peppermint and borneol, as well as some heat-sensitive root and rhizome herbs, the high-temperature environment can directly cause the volatilization or pyrolysis and oxidation of their active ingredients, severely reducing their efficacy. Furthermore, some devices, due to the simplistic movement of the grinding components, are prone to insufficient grinding and uneven powder particle size, further affecting the quality of Chinese medicine processing and the effectiveness of subsequent dosage form preparation. Summary of the Invention

[0004] The main objective of this invention is to provide a rotary grinding device for processing Chinese medicinal materials, which can effectively solve the problems of traditional devices lacking cooling function and insufficient grinding.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A rotary grinding device for processing Chinese medicinal materials includes a frame, a grinding chamber fixedly connected to the inner side of the frame, a support base one fixedly connected above the grinding chamber, a support base two fixedly connected above the support base one, a grinding assembly rotatably connected to the inner side of the support base two, a transmission assembly fixedly connected to the outer side of the frame on the grinding assembly, and the transmission assembly drives the grinding assembly to rotate, an air guide shell fixedly connected to the outer side of the frame on the grinding chamber, and a grid mesh fixedly connected to the right side of the air guide shell on the frame.

[0006] Preferably, the transmission assembly includes a drive motor, which is fixedly connected to the frame. A fan is rotatably connected to the frame on the left side of the air guide shell. A drive pulley is fixedly connected to the outside of the output shaft of the drive motor. A driven pulley is fixedly connected to the rear of the fan. The driven pulley and the drive pulley are driven by a belt. Heat dissipation fins are fixedly connected to the grinding chamber on the inside of the air guide shell.

[0007] Preferably, a first drive shaft and a second drive shaft are rotatably connected to the inner side of the frame. Both the first drive shaft and the second drive shaft are provided with pulleys and bevel gears on their outer sides. The pulley of the first drive shaft and the drive pulley are driven by a belt. The bevel gears of the first drive shaft and the second drive shaft mesh with each other. The other end of the first drive shaft and the second drive shaft are rotatably connected to a support base.

[0008] Preferably, the grinding assembly includes a drive turntable and a second cylindrical cam. The drive turntable is rotatably connected to a second support base. The drive turntable is driven by a belt through a pulley of a second transmission shaft. The second cylindrical cam has multiple guide posts on its upper surface and is slidably connected to the drive turntable through the guide posts. The first cylindrical cam is fixedly connected to the guide posts of the second cylindrical cam above the drive turntable.

[0009] Preferably, the second support base is fixedly connected to the outer side of the first cylindrical cam, and the inner side of the first auxiliary support is rotatably connected to the first driven roller.

[0010] Preferably, a grinding block is fixedly connected to the lower part of the cylindrical cam 2, an auxiliary bracket 2 is fixedly connected to the outer side of the cylindrical cam 2, and a driven roller 2 is rotatably connected to the inner side of the auxiliary bracket 2.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention provides a rotary grinding device for processing Chinese medicinal materials. When the drive motor drives the drive pulley to rotate, the driven pulley is simultaneously driven by the belt, causing the fan to generate negative pressure airflow. The airflow enters the air guide shell through the grid and flows along the heat dissipation fins on the outside of the grinding chamber, quickly carrying away the frictional heat of grinding. No additional power is required to achieve simultaneous grinding and cooling, control the temperature of the grinding chamber, and prevent the effective components of heat-sensitive and volatile medicinal materials such as peppermint and borneol from being volatilized or oxidized due to high temperature, thereby improving the efficacy retention rate of Chinese medicinal materials after grinding. This invention provides a rotary grinding device for processing Chinese medicinal materials. When the drive turntable rotates the cylindrical cam 2, the cylindrical cam 1 engages with the driven roller 1. Its contour curve pushes the cylindrical cam 2 to move axially back and forth along the guide post. This causes the grinding block below to form a compound action of continuous rotation and small-range reciprocating movement, avoiding the slippage and retention of medicinal materials and achieving full crushing of coarse and fine particles. Combined with the real-time sieving of the filter screen at the bottom of the grinding chamber, the obstruction of the already ground fine powder to subsequent grinding can be reduced, greatly improving the grinding efficiency and the uniformity of powder particle size.

[0014] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0015] like Figure 1 As shown, this invention provides a rotary grinding device for processing traditional Chinese medicine materials, including a frame 1. A grinding chamber 3 is fixedly connected to the inner side of the frame 1. A support base 8 is fixedly connected above the grinding chamber 3. A support base 9 is fixedly connected above the support base 8. A grinding component 6 is rotatably connected to the inner side of the support base 9. A transmission component 5 is fixedly connected to the outer side of the grinding component 6 on the frame 1, and drives the grinding component 6 to rotate through the transmission component 5. An air guide shell 4 is fixedly connected to the outer side of the grinding chamber 3 on the frame 1. A grid 14 is fixedly connected to the right side of the air guide shell 4 on the frame 1. A feed hopper 2 is directly connected to the top opening of the grinding chamber 3, and the user can continuously feed the traditional Chinese medicine materials to be ground through the feed hopper 2. A filter screen is built into the bottom of the grinding chamber 3, and the ground powder that has met the standards can be automatically screened and discharged.

[0016] like Figure 2As shown, this invention provides a rotary grinding device for processing traditional Chinese medicine materials. The transmission component 5 includes a drive motor 51, which is fixedly connected to the frame 1. A fan 55 is rotatably connected to the left side of the air guide shell 4. A drive pulley 54 is fixedly connected to the outside of the output shaft of the drive motor 51. A driven pulley 15 is fixedly connected to the rear of the fan 55. The driven pulley 15 and the drive pulley 54 are driven by a belt. A heat dissipation fin 7 is fixedly connected to the inner side of the air guide shell 4 in the grinding chamber 3. The fan 55 generates negative pressure when it rotates, and draws in ambient temperature airflow through the grid 14 on the right side of the frame 1. After the airflow enters the air guide shell 4, it flows along the surface of the heat dissipation fin 7 on the outside of the grinding chamber 3. The heat dissipation fin 7 increases the heat dissipation area of ​​the grinding chamber 3 and can quickly absorb the heat generated by friction in the grinding chamber 3. After the airflow and the heat dissipation fin 7 complete the heat exchange, it is discharged from the left side of the air guide shell 4, forming a continuously circulating heat dissipation channel, effectively controlling the internal temperature of the grinding chamber 3 and avoiding the loss of effective components of heat-sensitive medicinal materials.

[0017] like Figure 3 As shown, this invention provides a rotary grinding device for processing traditional Chinese medicine materials. A drive shaft 52 and a drive shaft 53 are rotatably connected to the inner side of the frame 1. Both drive shafts 52 and 53 have pulleys and bevel gears on their outer sides. The pulley of drive shaft 52 and the drive pulley 54 are driven by a belt. The bevel gears of drive shafts 52 and 53 mesh with each other. The other ends of drive shafts 52 and 53 are rotatably connected to a support base 8. An auxiliary bracket 10 is fixedly connected to the outer side of a cylindrical cam 61 on the support base 9. A driven roller 13 is rotatably connected to the inner side of the auxiliary bracket 10. Both drive shafts 52 and 53 are rotatably connected... It is attached to the inner side of the frame 1 and supported by support base 8 at both ends to ensure rotational stability; the bevel gear on the outer side of the transmission shaft 52 meshes with the bevel gear on the outer side of the transmission shaft 53, which transmits the horizontal rotational power of the transmission shaft 52 vertically to the transmission shaft 53, adapting to the vertical rotation requirements of the grinding assembly 6. The support base 9 has an auxiliary bracket 10 fixed on the outer side of the cylindrical cam 61. The driven roller 13 rotatably connected to the inner side of the auxiliary bracket 10 is tangentially attached to the cylindrical cam 61, which not only provides circumferential support for the cylindrical cam 61 to prevent it from shifting during rotation, but also reduces friction and wear with the cylindrical cam 61 through the rolling of the roller, ensuring the long-term stable operation of the cam structure.

[0018] like Figure 4As shown, this invention provides a rotary grinding device for processing traditional Chinese medicine materials. The grinding assembly 6 includes a drive turntable 62 and a cylindrical cam 63. The drive turntable 62 is rotatably connected to a support base 9. The drive turntable 62 is driven by a belt through a pulley on a transmission shaft 53. Multiple guide posts are provided above the cylindrical cam 63 and are slidably connected to the drive turntable 62. A cylindrical cam 61 is fixedly connected to the guide posts of the cylindrical cam 63 above the drive turntable 62. The drive turntable 62 receives power from the transmission shaft 53 via a belt and rotates synchronously. The disk 62 is slidably connected to the cylindrical cam 63 through multiple guide posts, which not only transmits the rotational power to the cylindrical cam 63, but also allows the cylindrical cam 63 to move axially along the guide posts. The top of the guide post of the cylindrical cam 63 is fixedly connected to the cylindrical cam 61. When the drive disk 62 drives the cylindrical cam 63 to rotate, the cylindrical cam 61 rotates synchronously. Since the cylindrical cam 61 is tangent to the driven roller 13, its contour curve will be subjected to the reaction force of the driven roller 13, which pushes the cylindrical cam 63 to make a small range of axial reciprocating movements along the guide post, realizing the conversion of rotation and reciprocating composite motion.

[0019] like Figure 5 As shown, the present invention provides a rotary grinding device for processing Chinese medicinal materials. A grinding block 64 is fixedly connected to the lower part of a cylindrical cam 63. An auxiliary bracket 11 is fixedly connected to the outer side of the cylindrical cam 63. A driven roller 12 is rotatably connected to the inner side of the auxiliary bracket 11. The driven roller 12 rotatably connected to the inner side of the auxiliary bracket 11 fits against the outer side of the cylindrical cam 63 and cooperates with the auxiliary bracket 10 and the driven roller 13 to form a double-layer circumferential support for the grinding assembly 6, thereby preventing the cylindrical cam 63 from shaking when it drives the grinding block 64 to grind.

[0020] The working principle of this rotary grinding device for processing Chinese medicinal materials will be explained in detail below.

[0021] like Figure 1-5As shown, when the drive motor 51 is started, its output shaft drives the drive pulley 54 fixed on the outside to rotate synchronously. The drive pulley 54 transmits power in two ways via a belt. One way is connected to the driven pulley 15 fixed behind the fan 55, driving the fan 55 to rotate; the other way is connected to the pulley on the outside of the first drive shaft 52, driving the first drive shaft 52 to rotate. The first drive shaft 52, through the bevel gear at its end, meshes with the bevel gear on the outside of the second drive shaft 53, converting the horizontal rotational power into vertical power, driving the second drive shaft 53 to rotate, thus achieving power splitting. At the same time, the fan 55... 5. When rotating, negative pressure is generated, and external ambient temperature airflow is drawn in through the grid mesh 14 fixed on the right side of the frame 1. After the airflow enters the air guide shell 4, it flows along the surface of the heat dissipation fins 7 fixed on the outside of the grinding chamber 3, quickly carrying away the heat generated by friction in the grinding chamber 3 during the grinding process. The airflow after heat exchange is discharged from the left side of the frame 1, forming a continuously circulating heat dissipation channel, effectively controlling the internal temperature of the grinding chamber 3, and avoiding the loss of effective components of heat-sensitive and volatile medicinal materials. The pulley on the outside of the second drive shaft 53 is connected to the drive turntable 62 through a belt, driving the drive turntable 62 to rotate stably inside the support seat 9. The drive turntable 62 is slidably connected to the cylindrical cam 63 via a guide post, transmitting rotational power to the cylindrical cam 63. Simultaneously, the cylindrical cam 61 fixed above the cylindrical cam 63 rotates synchronously. Since the support base 9 has an auxiliary bracket 10 fixed to the outside of the cylindrical cam 61, and the driven roller 13 rotatably connected to the inner side of the auxiliary bracket 10 is tangentially fitted to the cylindrical cam 61, when the cylindrical cam 61 rotates, its contour curve pushes the driven roller 13, which in turn acts on the cylindrical cam 61 and drives the cylindrical cam 63 to make a small-range axial reciprocating movement along the guide post. At the same time, the support base 9 is fixed to the outside of the cylindrical cam 63. The auxiliary support 2 11 has a driven roller 2 12 rotatably connected to its inner side, which fits against the outer side of the cylindrical cam 2 63. The auxiliary cylindrical cam 2 63 maintains stable rotation and reciprocating movement, which ultimately drives the grinding block 64 fixed below the cylindrical cam 2 63 to form a compound motion of continuous rotation and axial reciprocating movement. The user puts the Chinese medicinal materials to be processed into the grinding chamber 3 from the feed hopper 2. During the compound motion, the grinding block 64 applies a continuous squeezing and crushing force to the medicinal materials in the grinding chamber 3, gradually crushing and refining the lumpy medicinal materials. At the same time, the bottom of the grinding chamber 3 is equipped with a filter screen. When the particle size of the medicinal material powder reaches the preset standard, it will be screened and discharged through the filter screen.
