Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medicine quantitative dispensing, in particular to an automatic quantitative dispensing device for traditional Chinese medicine formula granules. BACKGROUND

[0002] Traditional Chinese medicine formula granules are granules made from traditional Chinese medicine decoction pieces as raw materials, which are prepared by extracting and concentrating single traditional Chinese medicine decoction pieces according to traditional standards for clinical dispensing of traditional Chinese medicine. The traditional Chinese medicine formula granules have the characteristics of portability, easy storage and use. During the production or dispensing process of traditional Chinese medicine formula granules, it is often necessary to quantitatively package or dispense the traditional Chinese medicine formula granules. In traditional operation, manual packaging or dispensing of traditional Chinese medicine formula granules is often used, but manual operation is inefficient and costly. Therefore, automatic dispensing equipment is gradually used to replace manual operation. At present, some automatic dispensing equipment uses quantitative weighing to package or dispense traditional Chinese medicine formula granules. However, each weighing needs a certain pause time to wait for the weight to stabilize to ensure the accuracy of the dispensing amount, which affects the efficiency of dispensing traditional Chinese medicine formula granules. Some automatic dispensing equipment dispenses or dispenses traditional Chinese medicine formula granules based on a set capacity, but traditional Chinese medicine formula granules are not liquids. Under the action of gravity, external pressure, etc., the weight of traditional Chinese medicine formula granules per unit volume will fluctuate greatly, which will affect the stability and accuracy of the dispensing amount.

[0003] Based on the above situation, a kind of medicine powder quantitative packaging device is disclosed in Chinese patent CN118701390A, which includes a storage cylinder and a packaging mechanism for quantitatively dispensing medicine powder. A shielding plate that can block the discharge port is slidably fixed at the discharge port of the storage cylinder. A cylindrical cavity is provided in the storage cylinder, and the packaging mechanism is arranged in the cylindrical cavity. The packaging mechanism includes a circular ring plate-shaped fixed block, a quantitative plate and a rotating block. The outer ring of the fixed block is fixed to the inner wall of the cylindrical cavity of the storage cylinder. The upper plate surface of the fixed block is concave. The quantitative plate is fixed and shields part of the inner edge of the fixed block. The rotating block is rotatably fixed below the quantitative plate. The upper surface of the rotating block is provided with a plurality of quantitative grooves. The grooves of the quantitative grooves can be completely covered by the quantitative plate. The discharge port is located directly below the quantitative plate. During the rotation of the quantitative grooves, the bottom through hole can be aligned with the discharge port.

[0004] The above-mentioned medicine powder quantitative packaging device can ensure that the volume of medicine powder packaged each time remains relatively stable based on a set capacity. Since the quantitative grooves are located at the bottom of the storage cylinder, the medicine powder in the quantitative grooves will be subjected to pressure generated by the gravity of other medicine powder inside the storage cylinder. However, this pressure will change with the amount of medicine powder in the storage cylinder. The medicine powder in the quantitative grooves will have different densities under different pressures, which will cause differences in the weight of medicine powder with a set capacity, thereby affecting the stability and accuracy of the medicine powder packaging amount. Therefore, there is still room for improvement in the above-mentioned medicine powder quantitative packaging device. SUMMARY

DETAILED DESCRIPTION

[0030] The embodiments of the present application will be described below in conjunction with the relevant drawings and examples, and the embodiments of the present application are not limited to the following examples, and the present application relates to the necessary components in the related technical field, which should be regarded as the known technology in the technical field, and is known and mastered by the person skilled in the art.

[0031] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, an automatic medicine particle dosing device includes a workbench 1, a medicine particle cylinder 2, and a driving mechanism 3. The workbench 1 is provided with a mounting hole 11, and the bottom of the mounting hole 11 is provided with a downwardly extending dosing channel 12. The bottom of the medicine particle cylinder 2 is located in the mounting hole 11, and the medicine particle cylinder 2 is hollow and forms a medicine particle cavity 21. A conveying sleeve 4 is sleeved on the bottom of the outside of the medicine particle cylinder 2, and a conveying cavity 41 is formed between the conveying sleeve 4 and the outside of the medicine particle cylinder 2 and is in communication with the bottom of the medicine particle cavity 21. A medicine particle outlet 42 is formed between the top of the conveying cavity 41 and the surface of the medicine particle cylinder 2 and is in communication with the dosing channel 12. A conveying rotating ring 5 is arranged between the bottom of the medicine particle cylinder 2 and the bottom of the conveying sleeve 4, and the conveying rotating ring 5 is provided with a plurality of conveying rotating plates 51 extending upward along the conveying cavity 41 in a spiral manner. The driving mechanism 3 is arranged at the connection between the mounting hole 11 and the dosing channel 12, and the output end of the driving mechanism 3 is in transmission cooperation with the conveying rotating ring 5 and drives the conveying rotating ring 5 to rotate along the axis of the conveying sleeve 4.

[0032] As a first preferred embodiment of the present application, the present application can be used for dispensing or dispensing and adjusting Chinese medicine formula particles (hereinafter referred to as medicine particles). The workbench 1 is used as a dosing device shell structure for fixing and supporting other components and providing protection. The medicine particle cylinder 2 is hollow and forms a medicine particle cavity 21 for temporarily containing medicine particles. If the present application is used for dispensing medicine particles, the top of the medicine particle cylinder 2 is connected with pipelines for conveying medicine particles. These pipelines are connected with medicine particle production and processing equipment and convey the processed medicine particles into the medicine particle cavity 21. The dosing device of the present application can be used for dispensing medicine particles and improving the efficiency of medicine particle dispensing. If the present application is used for dispensing and adjusting medicine particles, the medicine particle cavity 21 is used for temporarily storing medicine particles. The dosing device can be used for dispensing and adjusting medicine particles and mixing them with other types of medicine particles. The present application is mainly used for dispensing and adjusting medicine particles according to medicine prescriptions in the medical process, replacing inefficient manual dispensing and adjusting medicine particles, improving the efficiency of dispensing and adjusting medicine particles, and ensuring the accuracy of the amount of dispensing and adjusting medicine particles.

[0033] The driving mechanism 3 of the present application preferably adopts a driving motor, and the working principle of the charging device is as follows: after the medicine granule cavity 21 is filled with medicine granules, the driving mechanism 3 drives the conveying rotating ring 5 to rotate around its own axis, and the conveying rotating ring 5 drives a plurality of conveying rotating plates 51 to rotate synchronously during the rotation of the conveying rotating ring 5. It should be noted that the direction in which the conveying rotating ring 5 drives the conveying rotating plates 51 to rotate is opposite to the horizontal direction in which the conveying rotating plates 51 extend upwardly and obliquely relative to the horizontal plane. Since the medicine granules in the medicine granule cavity 21 are in a stationary state, the bottom of the conveying rotating plate 51 will shovel the medicine granules at the bottom of the intersection between the medicine granule cavity 21 and the conveying cavity 41 during the rotation of the conveying rotating plate 51. With the rotation of the conveying rotating plate 51, the medicine granules that are shoveled will gradually move upward along the surface of the conveying rotating plate 51 in the conveying cavity 41. When the conveying cavity 41 is filled with medicine granules, the medicine granules will gradually overflow from the medicine granule outlet 42 and fall into the charging channel 12. The medicine granules move along the charging channel 12 to the charging groove 13, and the charging groove 13 can accommodate a container containing the divided medicine granules or the medicine granules for dispensing. The angle or the number of rotations of the conveying rotating ring 5 can determine the amount of medicine granules overflowing from the medicine granule outlet 42. By setting the angle or the number of rotations of the conveying rotating ring 5 driven by the driving mechanism 3, the medicine granules can be quantitatively divided or quantitatively dispensed based on the set capacity.

[0034] It should be further noted that since the medicine granules in the conveying cavity 41 are isolated from the medicine granules in the medicine granule cavity 21 by the medicine granule cylinder 2 shell, the pressure generated by the gravity of the medicine granules in the medicine granule cavity 21 will not act on the medicine granules in the conveying cavity 41 in the vertical direction. The density of the medicine granules in the conveying cavity 41 is only affected by its own gravity. At the same time, since the medicine granules are filled from bottom to top in the conveying cavity 41 and then overflow from the medicine granule outlet 42, the amount of medicine granules in the conveying cavity 41 remains constant, so that the density of the medicine granules in the conveying cavity 41 can remain stable. Therefore, the weight of the medicine granules for quantitative division or quantitative dispensing based on the set capacity can remain stable, thereby improving the accuracy of the medicine granule division amount or the medicine dispensing amount.

[0035] It should be further noted that the conveying rotating plate 51 is provided with sealing rubber strips on both sides in the width direction, which abut against the surface of the medicine granule cylinder 2 and the inner wall of the conveying sleeve 4, respectively. The sealing rubber strips are preferably made of sealing rubber. The sealing rubber strips can improve the sealing performance of the conveying rotating plate 51 on both sides and the inner wall of the conveying cavity 41, and will not affect the normal movement of the conveying rotating plate 51. This avoids the medicine granules from falling downward from the gap between the conveying rotating plate 51 and the conveying cavity 41, thereby causing gaps in the medicine granules, so that the density of the medicine granules in the conveying cavity 41 remains stable, thereby improving the accuracy of the medicine granule division amount or the medicine dispensing amount.

[0036] As a second preferred embodiment of the present application, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 ,Figure 5 、 Figure 6 As shown in FIG. 1, the mounting holes 11 and the medicine pellet barrels 2 are provided with a plurality of matching mounting holes, respectively, and the charging channels 12 at the bottom of the mounting holes 11 extend to above the charging grooves 13, and the charging funnels 9 are provided above the charging grooves 13 and match the charging channels 12. After the above structure is adopted, the application is mainly used for dispensing medicine pellets. Different medicine pellets are stored in each medicine pellet barrel 2. The types of the medicine pellets stored in the medicine pellet barrels 2 are recorded by the servo system inside the charging device. When dispensing medicine pellets is needed, the required amount of each type of medicine pellet is input into the system, and the system will make the corresponding medicine pellet barrel 2 work according to the formula of the medicine pellets, so that the required amount of each type of medicine pellet is delivered to the charging channels 12, and finally gathered in the charging grooves 13 through the charging funnels 9, so that the prepared formula of the medicine pellets can be obtained in the charging grooves 13. The dispensing process does not need to weigh the medicine pellets manually, which is beneficial to improve the efficiency of dispensing the formula of the medicine pellets.

[0037] As one of the preferred embodiments of the application, as shown in FIG. 1, Figure 1 、 Figure 2 、 Figure 5 As shown in FIG. 1, the medicine pellet cavity 21 is provided with a plurality of guide plates 22 at the bottom. One end of the guide plate 22 is close to the shaft of the medicine pellet barrel 2, and the other end extends to the inner wall of the medicine pellet barrel 2. One side of the guide plate 22 is inclined downward to the conveying rotating ring 5. One end of the guide plate 22 extends from the position close to the shaft at the bottom of the medicine pellet cavity 21 to the edge of the bottom of the medicine pellet cavity 21. The extension direction of the guide plate 22 matches the rotation direction of the conveying rotating ring 5. The distance between the guide plate 22 and the conveying rotating ring 5 gradually decreases along the rotation direction of the conveying rotating ring 5. During the rotation of the conveying rotating ring 5, part of the medicine pellets close to the bottom of the medicine pellet cavity 21 are driven to move downward by the conveying rotating ring 5. These medicine pellets are guided by the guide plate 22 to move toward the conveying rotating ring 5 during the movement, so that the medicine pellets are always supplemented to the bottom of the conveying cavity 41, avoiding the appearance of gaps between the medicine pellets in the conveying cavity 41, which affects the density of the medicine pellets, and ensuring the accuracy of the amount of the medicine pellets.

[0038] As one of the preferred embodiments of the application, as shown in FIG. 1, Figure 1 、 Figure 2 、 Figure 7As shown, the bottom of the conveying rotary ring 5 is provided with a driven internal gear 52, the bottom of the medicine particle cylinder 2 is movably connected with a transmission gear 23 engaged with the driven internal gear 52, and the output end of the driving mechanism 3 is provided with a driving gear 31 engaged with the transmission gear 23; the driving gear 31, the transmission gear 23 and the driven internal gear 52 are transmission structures for driving the conveying rotary ring 5 to rotate by the driving mechanism 3, so that the conveying rotary ring 5 can be synchronously rotated when the driving mechanism 3 works, and the medicine particles at the bottom of the conveying cavity 41 are gradually conveyed upward to the medicine particle outlet 42 by the conveying spiral plates 51, so that the medicine particles enter the medicine loading channel 12 for medicine dispensing and adjusting.

[0039] Further, the plurality of guide plates 22 are collectively provided with a rotating shaft 24 movably connected with the medicine particle cylinder 2, the end of the rotating shaft 24 penetrates the bottom of the medicine particle cylinder 2 and is provided with a matching groove 25, and the top of the driving gear 31 is provided with a matching protrusion 32 matched with the matching groove 25; when the driving gear 31 is driven to rotate by the driving mechanism 3, the rotating shaft 24 is synchronously rotated in the same direction by the matching protrusion 32 and the matching groove 25 which are matched with each other and are not circular in shape, and at the same time, since the teeth of the driven internal gear 52 are located on the inner side, the driving gear 31 drives the driven internal gear 52 to rotate through the transmission gear 23, so that the rotating directions of the driving gear 31 and the driven internal gear 52 are opposite, and the rotating direction of the guide plate 22 is opposite to that of the conveying rotary ring 5, so that the guide plate 22 can directly push the medicine particles at the bottom of the medicine particle cavity 21 toward the conveying rotary ring 5 by the active rotation of the guide plate 22, and the medicine particles are continuously supplemented into the conveying cavity 41, so as to avoid the gaps between the medicine particles in the conveying cavity 41 and affect the density of the medicine particles, and ensure the accuracy of the medicine dispensing and adjusting amount.

[0040] As one of the preferred embodiments of the present application, as shown in Figure 1 , Figure 2 As shown, the top of the plurality of conveying spiral plates 51 is collectively provided with a connecting ring 53, and the outer side of the connecting ring 53 is provided with a medicine outlet inclined surface 54 inclined downward toward the medicine particle outlet 42; the medicine outlet inclined surface 54 can gradually reduce the width of the inside of the conveying cavity 41 close to the position of the medicine particle outlet 42, so that the medicine particles are gradually guided to the medicine particle outlet 42 by being extruded by the medicine outlet inclined surface 54 in the upward conveying process, avoiding that part of the medicine particles are retained at the top of the conveying cavity 41 and cannot fall into the medicine loading channel 12 through the medicine particle outlet 42, ensuring the stability of the conveying amount of the medicine particles by the internal structure of the conveying sleeve 4, and being beneficial to improve the accuracy of the medicine dispensing and adjusting amount.

[0041] As one of the preferred embodiments of the present application, as shown in Figure 1 , Figure 2 , Figure 8As shown, the inner side of the conveying rotary ring 5 and the bottom of the medicine pellet cylinder 2 are provided with a first sealing ring 6, which is preferably made of sealing rubber, and the first sealing ring 6 is annularly arranged on the inner side of the conveying rotary ring 5, so as to improve the sealing between the conveying rotary ring 5 and the medicine pellet cylinder 2, thereby avoiding the medicine pellets in the medicine pellet cavity 21 from leaking to the bottom of the medicine pellet cylinder 2 through the gap between the medicine pellet cylinder 2 and the conveying rotary ring 5, and meanwhile, the normal rotation of the conveying rotary ring 5 is not affected; the outer side of the conveying rotary ring 5 and the bottom of the conveying sleeve 4 are provided with a second sealing ring 7, which is preferably made of sealing rubber, and the second sealing ring 7 is annularly arranged on the outer side of the conveying rotary ring 5, so as to improve the sealing between the conveying rotary ring 5 and the conveying sleeve 4, thereby avoiding the medicine pellets in the conveying cavity 41 from leaking to the bottom of the conveying sleeve 4 through the gap between the conveying sleeve 4 and the conveying rotary ring 5, and meanwhile, the normal rotation of the conveying rotary ring 5 is not affected.

[0042] As one of the preferred embodiments of the present application, as shown in Figure 1 、 Figure 5 The top of the medicine pellet cylinder 2 is provided with a medicine pellet inlet, and the edge of the medicine pellet inlet is hingedly connected with a medicine cylinder top cover 26, and the top edge of the medicine pellet cylinder 2 and the top edge of the medicine cylinder top cover 26 are jointly provided with a fixed locking buckle 27 for fixing the medicine cylinder top cover 26; the medicine pellet inlet at the top of the medicine pellet cylinder 2 is used for loading medicine pellets into the medicine pellet cavity 21, and the medicine pellet inlet is covered by the medicine cylinder top cover 26 to form a relatively sealed space inside the medicine pellet cavity 21, so as to avoid the pollution of external pollutants into the medicine pellet cavity 21 to cause pollution to the medicine pellets, and the fixed locking buckle 27 can make the medicine cylinder top cover 26 more firmly cover the medicine pellet inlet.

[0043] As one of the preferred embodiments of the present application, as shown in Figure 1 、 Figure 2 The inner wall of the medicine pellet cylinder 2 is provided with medicine pellet monitoring elements 28 on the opposite sides, and the medicine pellet monitoring elements 28 are located close to the bottom of the medicine pellet cavity 21, and the medicine pellet monitoring elements 28 include an infrared emitter and an infrared receiver matched with each other, and whether the remaining amount of the medicine pellets in the medicine pellet cavity 21 is small is determined by identifying whether the infrared receiver can receive the infrared rays emitted by the infrared emitter; when the infrared receiver cannot receive the infrared rays, it indicates that the infrared rays are blocked by the medicine pellets, and the medicine pellets in the medicine pellet cavity 21 are still sufficient; when the infrared receiver can receive the infrared rays, it indicates that the top of the medicine pellets in the medicine pellet cavity 21 is below the medicine pellet monitoring elements 28, and the remaining amount of the medicine pellets in the medicine pellet cavity 21 is small, at this time, the medicine pellet prompt lamp 29 on the outer surface of the medicine pellet cylinder 2 is turned on to remind the operator to supplement the medicine pellets, so as to ensure that the amount of the medicine pellets in the medicine pellet cavity 21 is sufficient.

[0044] After the above structure, it is further explained that the medicine pellet cylinder 2 is provided with a connecting plug 8, and the workbench 1 is provided with a connecting socket 14 matched with the connecting plug 8 at the edge of the mounting hole 11. The workbench 1 is connected with the power supply line through the plug and other components, so as to provide the driving mechanism 3 with the necessary power for operation.

[0045] As one of the preferred embodiments of the present application, as shown in Figure 1 、 Figure 2 The inner diameter of the inner wall of the medicine pellet cylinder 2 near the bottom gradually decreases and forms an inclined surface. The inclined surface formed by the inner wall of the medicine pellet cylinder 2 can better guide and gather the medicine pellets in the medicine pellet cavity 21 to the bottom, so as to avoid that the medicine pellets are too loose inside. The inner diameter of the inner wall of the conveying sleeve 4 near the bottom gradually decreases and forms an inclined surface. The inclined surface formed by the inner wall of the conveying sleeve 4 can keep the width of the conveying cavity 41 consistent, so as to avoid that there is a large gap between the conveying spiral plate 51 and the conveying cavity 41, and the medicine pellets in the conveying cavity 41 slide down along the gap.

[0046] In summary, the present application is mainly used for dispensing and adjusting traditional Chinese medicine formula pellets. The rotating conveying ring 5 gradually conveys the medicine pellets at the bottom of the conveying cavity 41 upward through the conveying spiral plates 51. The medicine pellets in the conveying cavity 41 overflow through the medicine pellet outlet 42 and are conveyed into the medicine loading groove 13 through the medicine loading channel 12. The medicine pellets are quantitatively dispensed and adjusted by setting the capacity. The pressure generated by the gravity of the medicine pellets in the medicine pellet cavity 21 does not act on the medicine pellets in the conveying cavity 41 in the vertical direction, and the amount of the medicine pellets in the conveying cavity 41 remains constant, so that the density of the medicine pellets in the conveying cavity 41 can remain stable, the weight of the set capacity of the medicine pellets can remain stable, and the accuracy of the medicine pellet dispensing and adjusting amount is improved.

[0047] The above is only the preferred embodiment of the present application. It should be pointed out that those skilled in the art can make some improvements and refinements without departing from the principles of the present application. These improvements and refinements should also be considered as the protection scope of the present application.
