[0019] 2. The present invention provides a drug grinding device for dermatology before applying medicine to the affected part. A screening chamber is provided in the outer shell below the grinding chamber for further screening of drugs that meet the requirements; specifically, a circular screening element is provided in the screening chamber, and a plurality of screening holes are provided at the bottom of the screening element.

[0020] 3.

During the rotation of the screening member, the medicine will be subjected to the action of centrifugal force. When the rotation speed remains unchanged, the greater the mass (particle size) of the particles, the greater the centrifugal force received, that is, large-particle-size medicines will fly out of the collecting holes under the action of centrifugal force and fall into the recovery chamber, and small-particle-size medicines will fall into the collection box from the small holes of the screening member, thereby further realizing the screening effect of the medicines and avoiding the accumulation of large-particle medicines on the screening member, which affects the recovery of small-particle medicines.

The driven rotating shaft is connected to the driving pulley, and the connecting rod is connected to the driven pulley. A second transmission belt is connected between the driving pulley and the driven pulley. The driving rotating shaft rotates, driving the driven rotating shaft through the driving conical pulley, the driven conical pulley, and the first transmission belt. The driven rotating shaft drives the connecting rod to rotate through the driving pulley, the driven pulley, and the second transmission belt, so that the screening element follows the eccentric rotation of the connecting rod to vibrate and screen the drug. Through the design of the driving conical pulley and the driven conical pulley, the particle size of the drug powder screened by the screening element can be positively correlated with the particle size of the drug powder ground by the conical grinding table, further improving the uniformity of the drug powder. For example, if it is necessary to reduce the particle size of the drug after grinding, the grinding table is moved downward to reduce the gap between the outer wall of the grinding table and the inner wall of the grinding chamber. At the same time, the active conical pulley also moves downward, and the working diameter of the active conical pulley is reduced, resulting in an increase in the rotation speed of the driven conical pulley, which in turn increases the rotation speed of the screening element. The centrifugal force on the drug in the screening element increases, and then drug particles smaller than the previous state will also enter the recovery chamber from the collection hole due to the action of centrifugal force, and then be placed in the grinding chamber for grinding until they are ground into particle size that meets the requirements.

Specifically, the base 1 is provided with a guide groove 2, one end of the guide groove 2 passes through the base 1, and a guide bar 4 is provided at the bottom of the collecting box 3. The guide bar 4 is arranged in cooperation with the guide groove 2. The guide groove 2 passes through one end of the base 1 as an inlet, and the other end plays a positioning role.

[0033] The specific implementation process is as follows:

[0034] When using the device, the medicine is put into the feeding port 7, the motor 16 is started, the motor 16 drives the active shaft 12 to rotate, and the active shaft 12 drives the grinding table 13 to rotate relative to the grinding chamber 8 to grind the medicine. The ground medicine powder falls onto the screening element 29, ensuring the particle size and uniformity of the medicine; at the same time, the active shaft 12 drives the driven shaft 21 to rotate through the active conical pulley 20, the driven conical pulley 22 and the first transmission belt 23, and the driven shaft 21 drives the connecting rod through the active pulley 26, the driven pulley 27 and the second transmission belt 28 25 rotates, so that the screening member 29 rotates eccentrically with the connecting rod 25, so as to realize vibration screening of the ground medicine, prevent the medicine with too large particles from falling into the collecting box 3, and further ensure the uniformity and particle size of the ground medicine; when it is necessary to increase or decrease the particle size of the medicine, the driving assembly 17 is used to move the grinding table 13 upward or downward to achieve effective adjustment of the particle size; in addition, the screening assembly and the connecting rod 25 can be detachably connected to the connecting rod 25 by a buckle or a bolt, so as to facilitate the disassembly, cleaning or replacement of the screening member 29.

[0035] Example 2: The difference between this example and Example 1 is that this example further includes: the side wall of the screening element 29 farthest from the connecting rod 25 is cooperated with the inner wall of the screening chamber 9, and the side wall of the screening element 29 farthest from the connecting rod 25 is provided with a plurality of collecting holes 30; the outer shell 5 is provided with an annular recovery chamber 10, and the recovery chamber 10 is provided with an opening on the side facing the screening chamber 9 so that the collecting holes 30 and the recovery chamber 10 remain in a connected state; the recovery chamber 10 is provided with a material taking port to facilitate the removal of the recovered drugs therein for secondary grinding.

[0036] The specific implementation process is as follows:

[0037] When using the device, the medicine is put into the feeding port 7, the motor 16 is started, the motor 16 drives the active shaft 12 to rotate, and the active shaft 12 drives the grinding table 13 to rotate relative to the grinding chamber 8 to grind the medicine. The ground medicine powder falls onto the screening element 29 to ensure the particle size and uniformity of the medicine; at the same time, the active shaft 12 drives the driven shaft 21 to rotate through the active conical pulley 20, the driven conical pulley 22 and the first transmission belt 23, and the driven shaft 21 drives the connecting rod 25 to rotate through the active pulley 26, the driven pulley 27 and the second transmission belt 28, so that the screening element 29 follows the eccentric rotation of the connecting rod 25 to achieve vibration screening of the ground medicine, and prevent the medicine with too large particles from falling into the collection box 3. In addition, during the rotation of the screening element 29, the medicine on it is subjected to centrifugal force. The medicine with larger particles is subjected to greater centrifugal force and enters the recovery chamber 10 from the collection hole 30 to further ensure the uniformity and particle size of the ground medicine, and the medicine with larger particles in the recovery chamber 10 can be recovered later. The medicine is placed in the grinding chamber 8 and ground again, and the cycle continues until the particle size meets the requirements. When the particle size of the medicine needs to be increased or decreased, the driving assembly 17 is used to move the grinding table 13 upward or downward to increase or decrease the grinding gap 14. For example, if the particle size of the ground medicine needs to be reduced, the grinding table 13 is moved downward to reduce the gap between the outer wall of the grinding table 13 and the inner wall of the grinding chamber 8. At the same time, the active conical pulley 20 also moves downward, and the working diameter of the active conical pulley 20 is reduced, resulting in an increase in the rotation speed of the driven conical pulley 22, thereby increasing the rotation speed of the screening element 29 and increasing the centrifugal force on the medicine in the screening element 29. Then, the medicine particles smaller than the previous state will also enter the recovery chamber 10 from the collection hole 30 due to the centrifugal force, and then the recovered medicine is placed in the grinding chamber 8 and ground again until it is ground into the required particle size, so as to achieve a positive correlation between the powder particle size screened by the screening element 29 and the particle size of the ground powder by the conical grinding table 13, thereby further improving the uniformity of the medicine powder.

[0038] Example 3: The difference between this example and Example 2 is that a negative pressure suction component 31 is also provided in the recovery chamber 10, and the outlet of the negative pressure suction component 31 is connected to the grinding chamber 8 through a connecting tube 33. The negative pressure suction component 31 is used to recover the medicine in the recovery chamber 10 to the grinding chamber 8.

[0039] The specific implementation process differs from that of Example 2 in that: there is no need for manual operation to put the recovered large-particle medicine back into the grinding chamber 8 , but the medicine is sucked into the grinding chamber 8 through the negative pressure suction component 31 .

[0040] In addition, for Examples 1 to 3, when it is necessary to clean the internal parts, the collection box 3 can be removed and the screening element 29 can be removed; the bolts or pins on the end cover 6 can be removed to remove the end cover 6 from the outer shell 5, and then the bolts or pins on the mounting cover 11 and the outer shell 5 can be removed to remove the mounting cover 11 from the outer shell 5, and then the first transmission belt 23 can be removed from the driven conical pulley 22, and finally the mounting cover 11, the end cover 6, the driving shaft 12 and the grinding table 13 can be separated from the outer shell 5 to facilitate cleaning of the grinding table 13 and the grinding chamber 8.

[0041] Among them, the grinding chamber 8 cooperates with the grinding table 13 to grind the medicine; the end cover 6 is provided with several feeding ports 7 for putting in raw materials; the base 1 is detachably connected to the mounting cover 11, and the end cover 6 is detachably connected to the shell 5, so as to facilitate the separation of the end cover 6, the grinding table 13 and the shell 5, so as to realize the cleaning of the grinding chamber 8 and the grinding table 13; the motor 16 drives the active rotating shaft 12 to rotate, and the active rotating shaft 12 drives the grinding table 13 to rotate relative to the grinding chamber 8 to realize the grinding of the medicine with high efficiency, and the end cover 6 and the shell 5 cooperate with each other to avoid the contamination of the medicine and improve the medicinal properties of the medicine; a collecting box 3 is provided below the grinding chamber 8 for collecting the ground medicinal powder; the collecting box 3 is detachably connected to the base 1, so as to facilitate the removal of the collecting box 3, increase efficiency and save time; and the collecting box 3 and the shell 5 form a closed space, which further avoids the contamination of the medicine and ensures the quality of the medicine. The utility model relates to a grinding wheel 14, wherein the grinding wheel 14 is provided with a grinding gap 14, and the grinding wheel 14 is provided with a grinding gap 14. The axes of the grinding wheel 13, the active rotating shaft 12 and the grinding chamber 8 are collinear, so as to realize the uniformity of the gap between the grinding wheel 13 and the grinding chamber 8, thereby effectively controlling the uniformity of the drug particles and increasing the drug absorption effect. In addition, the mounting plate 15 is slidably connected to the mounting cover 11, and the mounting cover 11 is connected to a driving assembly 17 for driving the mounting plate 15 to slide along the axial direction of the active rotating shaft 12. By adjusting the grinding table 13 along the axial direction of the active rotating shaft 12, the gap between the grinding table 13 and the grinding chamber 8 can be adjusted, thereby realizing the control of the drug particle size, further increasing the grinding effect and improving the patient's absorption rate of the drug.

[0042] A screening chamber 9 is provided in the housing 5 below the grinding chamber 8 for further screening of drugs that meet the requirements; the ground drugs fall from the grinding gap 14 to the screening member 29, and the active shaft 12 drives the grinding table 13 to grind, and also drives the connecting rod 25 to rotate through the linkage assembly, and the connecting rod 25 drives the eccentric rotation with the screening member 29 to achieve vibration of the drugs thereon for further screening, further realize the control of drug uniformity, and increase the patient's absorption of the drugs.

[0043] The side wall of the screening element 29 farthest from the connecting rod 25 is cooperated with the inner wall of the screening chamber 9 to ensure that the side can always contact the inner wall of the screening chamber 9 during the rotation of the screening element 29; the side wall of the screening element 29 farthest from the connecting rod 25 is provided with a plurality of collecting holes 30, and the outer shell 5 is provided with an annular recovery chamber 10, and the recovery chamber 10 is provided with an opening on the side facing the screening chamber 9 so that the collecting holes 30 and the recovery chamber 10 remain in a connected state. Large-particle drugs will fly out of the collecting holes 30 under the action of centrifugal force and fall into the recovery chamber 10, and small-particle drugs will fall into the collection box 3 from the small holes of the screening element 29, further realizing the screening effect of the drugs, and can avoid large-particle drugs from accumulating on the screening element 29 and affecting the recovery of small-particle drugs. In addition, in order to improve efficiency and increase resource utilization, a negative pressure suction component 31 (such as a suction pump) is provided in the recovery chamber 10. The outlet of the negative pressure suction component 31 is connected to the grinding chamber 8. The negative pressure suction component 31 can recover the larger particles in the recovery chamber 10 and the drugs that do not meet the requirements into the grinding chamber 8 for re-grinding, thereby increasing the utilization rate of the drugs and saving resources. The grinding of recovered drugs and new raw materials can be carried out at the same time, thereby increasing the grinding efficiency.

[0044] The design of the active conical pulley 20 and the driven conical pulley 22 can ensure that the particle size of the drug powder screened by the screening element 29 is positively correlated with the particle size of the drug powder ground by the conical grinding table 13, further improving the uniformity of the drug powder. For example, if the particle size of the ground drug needs to be reduced, the grinding table 13 is moved downward to reduce the gap between the outer wall of the grinding table 13 and the inner wall of the grinding chamber 8. At the same time, the active conical pulley 20 also moves downward, and the working diameter of the active conical pulley 20 decreases, resulting in an increase in the rotation speed of the driven conical pulley 22, which in turn increases the rotation speed of the screening element 29. The centrifugal force on the drug in the screening element 29 increases, and drug particles smaller than in the previous state will also enter the recovery chamber 10 from the collection hole 30 due to the centrifugal force, and then be placed in the grinding chamber 8 for grinding until they are ground to the required particle size.

[0045] The outer shell 5 is connected to a protective box 24, which can prevent the linkage assembly from contaminating the medicine. The outer surface of the grinding table 13 is provided with a spiral protrusion 32, and the rotation direction is the same as the rotation direction of the rotating shaft, which can not only further achieve the crushing effect on the medicine, but also guide the medicine. The base 1 is provided with a guide groove 2, and the bottom of the collection box 3 is provided with a guide bar 4, which is convenient for taking and placing the collection box 3, and can also play a role in positioning the collection box 3. A "convex" shaped slide groove 18 is provided on the inner side of the mounting cover 11, and the mounting plate 15 is connected to a "convex" shaped slide rail 19. The slide rail 19 is slidably connected to the slide groove 18, which can ensure the stability of sliding and share the torsional force of the rotating shaft on the drive assembly 17.

[0046] The above is only an embodiment of the present invention, and common knowledge such as the specific technical solutions or characteristics in the solution is not described in detail here.
