Description

Technical Field

[0001] The invention relates to the technical field of quantitative drug dispensing, and in particular to an automatic quantitative dispensing device for traditional Chinese medicine formula granules. Background Art

[0002] Chinese medicine formula granules are made from traditional Chinese medicine slices, which are extracted and concentrated after being processed according to traditional standards. They are used for clinical prescriptions of traditional Chinese medicine. They are portable, easy to store and use. Chinese medicine formula granules usually need quantitative packaging or quantitative adjustment during production or dispensing. In traditional operations, Chinese medicine formula granules are often packaged or dispensed manually, but manual operation is inefficient and costly, so automatic loading equipment is gradually used to replace manual operation. At present, some automatic loading equipment uses quantitative weighing to package or dispense Chinese medicine granules, but each weighing requires a certain pause time for the weight to stabilize to ensure the accuracy of the loading amount, which affects the efficiency of Chinese medicine formula granule loading. Some automatic loading equipment also packages or dispenses Chinese medicine granules based on the set capacity, but Chinese medicine formula granules are not liquids. Under the action of gravity, external pressure, etc., the weight of Chinese medicine formula granules per unit volume will fluctuate greatly, which is easy to affect the stability and accuracy of the loading amount.

[0003] Based on the above situation, a Chinese patent with announcement number CN118701390A discloses a quantitative powder filling device, including a storage cylinder and a filling mechanism for quantitatively filling powder. A shielding plate that can block the discharge port can be slidably fixed at the discharge port of the storage cylinder. A cylindrical cavity is arranged in the storage cylinder, and the filling mechanism is arranged in the cylindrical cavity. The filling mechanism includes a fixed block in the shape of an annular plate, a quantitative plate and a rotating block. The outer ring of the annular plate of the fixed block is fixed against 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 blocks part of the inner edge of the fixed block, the rotating block can be rotatably fixed under the quantitative plate, and a plurality of quantitative grooves are opened on the upper surface of the rotating block. The notches of the quantitative grooves can be completely covered by the quantitative plate, and the discharge port is opened directly below the quantitative plate. During the rotation of the quantitative groove, the through hole at the bottom can face the discharge port.

[0004] The powder quantitative packaging device disclosed in the above patent packages the powder based on the set capacity through multiple quantitative grooves, which can ensure that the volume of the powder packaged each time remains relatively stable. Since the quantitative grooves are located at the bottom of the storage barrel, the powder in the quantitative grooves will be subject to the pressure generated by gravity of other powders inside the storage barrel, but the pressure will change with the amount of powder in the storage barrel. The powder in the quantitative grooves will present different densities under different pressures, resulting in differences in the weight of the powder with the set capacity, thereby affecting the stability and accuracy of the powder packaging amount. Therefore, the above powder quantitative packaging device still has room for improvement. Summary of the invention

DETAILED DESCRIPTION

[0025] The implementation modes of the present invention are described below in conjunction with relevant drawings and embodiments. The implementation modes of the present invention are not limited to the following embodiments, and the present invention relates to relevant necessary components in the technical field, which should be regarded as the known technology in the technical field and can be known and mastered by the technical personnel in the technical field.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, an automatic quantitative medicine loading device for medicine pellets comprises a workbench 1, a medicine pellet barrel 2, and a driving mechanism 3. A mounting hole 11 is provided on the surface of the workbench 1, a medicine loading channel 12 extending downward is provided at the bottom of the mounting hole 11, and a medicine loading groove 13 is provided at the end of the medicine loading channel 12; the bottom of the medicine pellet barrel 2 is located in the mounting hole 11, the inside of the medicine pellet barrel 2 is hollow and forms a medicine pellet cavity 21, a conveying sleeve 4 is sleeved on the bottom of the outer side of the medicine pellet barrel 2, and a seal is formed between the conveying sleeve 4 and the outer side of the medicine pellet barrel 2 and the bottom of the medicine pellet cavity 21 A conveying cavity 41 is interconnected with each other, a medicine particle outlet 42 connected to the charging channel 12 is formed between the top of the conveying cavity 41 and the surface of the medicine particle barrel 2, a conveying swivel 5 is arranged between the bottom of the medicine particle barrel 2 and the bottom of the conveying sleeve 4, and the conveying swivel 5 is provided with a plurality of conveying rotary plates 51 extending upward along the spiral of the conveying cavity 41; a driving mechanism 3 is arranged at the connection between the mounting hole 11 and the charging channel 12, and the output end of the driving mechanism 3 is matched with the conveying swivel 5 to make the conveying swivel 5 rotate along the axis of the conveying sleeve 4.

[0027] As a first preferred embodiment of the present invention, the present invention can be used for packing or dispensing Chinese medicine granules (hereinafter referred to as granules). The workbench 1 is used as the outer shell structure of the charging device to fix other components and provide support and protection. The inside of the granule barrel 2 is hollow to form a granule cavity 21 for temporarily accommodating granules. If the present invention is used for packing granules, the top of the granule barrel 2 is connected with a pipeline for conveying granules. These pipelines are connected to the equipment for producing and processing granules and convey the produced and processed granules to the granule cavity 21. The granules can be packed by the charging device of the present invention, thereby improving the efficiency of granule packing. If the present invention is used for dispensing and adjusting granules, the granule cavity 21 is used to temporarily store granules. The granules are quantitatively distributed and mixed with other types of granules by the charging device. It is mainly used for dispensing and adjusting according to drug prescriptions in medical treatment, replacing inefficient manual dispensing and adjusting, improving the efficiency of dispensing and adjusting, and ensuring the accuracy of the dispensing and adjusting amount.

[0028] The driving mechanism 3 of the present invention preferably adopts a driving motor. The working principle of the medicine charging device is as follows: when the medicine particle cavity 21 is filled with medicine particles, the driving mechanism 3 drives the conveying swivel 5 to rotate with its own axis as the axis. During the rotation of the conveying swivel 5, it will drive a number of conveying rotary plates 51 to rotate synchronously. It should be noted that the direction in which the conveying swivel 5 drives the conveying rotary plates 51 to rotate is opposite to the horizontal direction in which the conveying rotary plates 51 extend obliquely upward relative to the horizontal plane. Since the medicine particles in the medicine particle cavity 21 are in a stationary state, during the rotation of the conveying rotary plates 51, their bottom will scoop up the medicine particles at the bottom of the intersection of the medicine particle cavity 21 and the conveying cavity 41, and as the conveying rotary plates As the conveying ring 51 rotates, the scooped medicine particles in the conveying chamber 41 will gradually move upward along the surface of the conveying rotary plate 51. When the conveying chamber 41 is filled with medicine particles, the medicine particles will gradually overflow from the medicine particle outlet 42 and fall into the charging channel 12. The medicine particles move along the charging channel 12 to the charging trough 13. The charging trough 13 can be used to place a container for accommodating the packaged medicine particles or the medicine particles for dispensing and adjustment. The angle or number of rotations of the conveying ring 5 can determine the amount of medicine particles overflowing from the medicine particle outlet 42. By driving the conveying ring 5 to rotate a set angle or number of turns through the driving mechanism 3, the medicine particles can be quantitatively packaged or quantitatively dispensed based on the set capacity.

[0029] It should be further explained that, since the medicine particles in the conveying chamber 41 are isolated from the medicine particles in the medicine particle chamber 21 by the outer shell of the medicine particle tube 2, the pressure generated by the gravity of the medicine particles in the medicine particle chamber 21 will not act on the medicine particles in the conveying chamber 41 in the vertical direction, and the density of the medicine particles in the conveying chamber 41 will only be affected by their own gravity. At the same time, since the medicine particles are filled into the conveying chamber 41 from bottom to top through the rotation of the conveying ring 5 and then overflow from the medicine particle outlet 42, the amount of medicine particles in the conveying chamber 41 will remain constant, so that the density of medicine particles in the conveying chamber 41 can remain stable, then the weight of medicine particles for quantitative packaging or quantitative dispensing based on the set capacity can remain stable, thereby improving the accuracy of the medicine particle packaging amount or the dispensing amount.

[0030] It should be further explained that sealing strips are provided on both sides of the width direction of the conveying rotary plate 51, which are respectively in contact with the surface of the medicine pellet barrel 2 and the inner wall of the conveying sleeve 4. The sealing strips are preferably made of sealing rubber. The sealing strips can improve the sealing between the two sides of the conveying rotary plate 51 and the inner wall of the conveying cavity 41, and will not affect the normal movement of the conveying rotary plate 51, thereby preventing medicine pellets from falling downward from the gap between the conveying rotary plate 51 and the conveying cavity 41 and causing gaps inside the medicine pellets, thereby maintaining a stable density of medicine pellets in the conveying cavity 41, thereby improving the accuracy of medicine pellet packaging or dosage adjustment.

[0031] As a second preferred embodiment of the present invention, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, the mounting holes 11 and the medicine pellet barrel 2 are both provided with several and matched with each other one by one, and the medicine charging channels 12 at the bottom of the mounting holes 11 are all extended to the top of the medicine charging groove 13, and the medicine charging funnel 9 matched with the several medicine charging channels 12 is provided above the medicine charging groove 13; after adopting the above structure, the present invention is mainly used for dispensing and adjusting medicine pellets, each medicine pellet barrel 2 is respectively stored with different medicine pellets, and the types of medicine pellets respectively stored in the medicine pellet barrel 2 are recorded by the servo system inside the medicine charging device. When dispensing and adjusting are needed, only the amount of medicine pellets required for various medicine pellets needs to be input into the system, and the system will make the medicine pellet barrel 2 of the corresponding medicine pellet work according to the formula of the medicine pellets, and quantitatively transport various medicine pellets to the medicine charging channel 12, and various medicine pellets are finally gathered into the medicine charging groove 13 through the medicine charging funnel 9, so that the prepared medicine pellet formula can be obtained in the medicine charging groove 13, and the medicine dispensing and adjusting process does not need to weigh the medicine pellets manually, which is conducive to improving the efficiency of medicine pellet formula dispensing and adjusting.

[0032] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 , Figure 5 As shown, a plurality of guide plates 22 are provided at the bottom of the medicine grain cavity 21, one end of the guide plate 22 is close to the axis of the medicine grain barrel 2, and the other end extends toward the inner wall of the medicine grain barrel 2, and one side of the guide plate 22 is inclined downward toward the conveying swivel 5; one end of the guide plate 22 extends from a position close to the axis of the bottom of the medicine grain cavity 21 toward the bottom edge of the medicine grain cavity 21, and the extension direction of the guide plate 22 matches the rotation direction of the conveying swivel 5, and the distance between the guide plate 22 and the conveying swivel 5 gradually decreases along the rotation direction of the conveying swivel 5. During the rotation of the conveying swivel 5, some medicine grains close to the bottom of the medicine grain cavity 21 will be driven by the conveying swivel 5 to move simultaneously, and these medicine grains will be gradually guided by the guide plate 22 along the guide plate 22 toward the side of the conveying swivel 5 during the movement and move toward the conveying swivel 5, so that medicine grains are always replenished to the bottom of the conveying cavity 41, avoiding the occurrence of gaps between the medicine grains inside the conveying cavity 41 and affecting the density of the medicine grains, thereby ensuring the accuracy of the medicine grain dispensing and dosage adjustment.

[0033] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 , Figure 7As shown, a driven internal gear 52 is provided at the bottom of the conveying swivel 5, a transmission gear 23 meshing with the driven internal gear 52 is movably connected to the bottom of the medicine pellet barrel 2, and a driving gear 31 meshing with the transmission gear 23 is provided at the output end of the driving mechanism 3; the driving gear 31, the transmission gear 23, and the driven internal gear 52 serve as a transmission structure for the driving mechanism 3 to drive the conveying swivel 5 to rotate. When the driving mechanism 3 is working, the conveying swivel 5 can be made to rotate synchronously. The rotating conveying swivel 5 gradually conveys the medicine pellets at the bottom of the conveying cavity 41 upward to the medicine pellet outlet 42 through a plurality of conveying rotary plates 51, so that the medicine pellets enter the medicine charging channel 12 for medicine pellet dispensing and adjustment.

[0034] Furthermore, the plurality of guide plates 22 are commonly provided with a rotating shaft 24 movably connected to the medicine pellet barrel 2, the end of the rotating shaft 24 passes through the bottom of the medicine pellet barrel 2 and is provided with a matching groove 25, and the top of the driving gear 31 is provided with a matching protrusion 32 matching the matching groove 25; when the driving mechanism 3 rotates the driving gear 31, the rotating shaft 24 is synchronously rotated in the same direction through the matching protrusion 32 and the matching groove 25, which are matched with each other and whose surface shapes are not circular. At the same time, since the gear teeth of the driven internal gear 52 are located on the inner side, The driving gear 31 rotates the driven internal gear 52 through the transmission gear 23, so that the driving gear 31 rotates in opposite directions to the driven internal gear 52. Therefore, the guide plate 22 rotates in opposite directions to the conveying rotating ring 5. Through the active rotation of the guide plate 22, the guide plate 22 can directly push the medicine particles at the bottom of the medicine particle cavity 21 toward the conveying rotating ring 5, and continuously replenish the medicine particles into the conveying cavity 41, thereby avoiding the appearance of gaps between the medicine particles inside the conveying cavity 41 and affecting the density of the medicine particles, thereby ensuring the accuracy of the medicine particle dispensing and dosage adjustment.

[0035] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 As shown, a connecting ring 53 is provided on the top of several conveying rotary plates 51, and a medicine discharge slope 54 is provided on the outer side of the connecting ring 53, which is inclined downward toward the medicine particle outlet 42; the medicine discharge slope 54 can gradually reduce the width of the conveying cavity 41 near the medicine particle outlet 42, so that the medicine particles are squeezed by the medicine discharge slope 54 during the upward conveying process and are gradually guided to the medicine particle outlet 42, so as to avoid that some medicine particles are retained at the top of the conveying cavity 41 and cannot fall into the medicine charging channel 12 through the medicine particle outlet 42, thereby ensuring the stability of the internal structure of the conveying sleeve 4 to the medicine particle conveying amount, which is beneficial to improving the accuracy of medicine particle dispensing and dosage adjustment.

[0036] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 , Figure 8As shown, a first sealing ring 6 is provided between the inner side of the conveying swivel 5 and the bottom of the medicine pellet barrel 2. The first sealing ring 6 is preferably made of sealing rubber. The first sealing ring 6 is in a circular ring shape and surrounds the inner side of the conveying swivel 5. The first sealing ring 6 can improve the sealing between the conveying swivel 5 and the medicine pellet barrel 2, thereby preventing the medicine pellets in the medicine pellet chamber 21 from leaking to the bottom of the medicine pellet barrel 2 through the gap between the medicine pellet barrel 2 and the conveying swivel 5, and will not affect the normal rotation of the conveying swivel 5; a second sealing ring 7 is provided between the outer side of the conveying swivel 5 and the bottom of the conveying sleeve 4. The second sealing ring 7 is preferably made of sealing rubber. The second sealing ring 7 is in a circular ring shape and surrounds the outer side of the conveying swivel 5. The second sealing ring 7 can improve the sealing between the conveying swivel 5 and the conveying sleeve 4, thereby preventing 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 swivel 5, and will not affect the normal rotation of the conveying swivel 5.

[0037] As one of the preferred embodiments of the present invention, Figure 1 , Figure 5 As shown, a medicine pellet inlet is provided at the top of the medicine pellet cartridge 2 and a medicine pellet top cover 26 is hingedly connected to the edge of the medicine pellet inlet. A fixing lock buckle 27 is provided at the top edge of the medicine pellet cartridge 2 and the top edge of the medicine pellet top cover 26 for fixing the medicine pellet top cover 26. The medicine pellet inlet at the top of the medicine pellet cartridge 2 is used to load medicine pellets into the medicine pellet cavity 21. The medicine pellet inlet is sealed by the medicine pellet top cover 26 to form a relatively sealed space inside the medicine pellet cavity 21, so as to prevent external contaminants from entering the medicine pellet cavity 21 and contaminating the medicine pellets. The fixing lock buckle 27 can make the medicine pellet top cover 26 more firmly sealed at the medicine pellet inlet.

[0038] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 As shown, medicine grain monitoring elements 28 are provided on opposite sides of the inner wall of the medicine grain barrel 2. The medicine grain monitoring elements 28 are located near the bottom of the medicine grain cavity 21. The medicine grain monitoring elements 28 include an infrared transmitter and an infrared receiver that match each other. It is determined whether the remaining amount of medicine grains in the medicine grain cavity 21 is small by identifying whether the infrared receiver can receive the infrared rays emitted by the infrared transmitter. When the infrared receiver cannot receive the infrared rays, it indicates that the infrared rays are blocked by the medicine grains, and the medicine grains in the medicine grain cavity 21 are still sufficient. When the infrared receiver can receive the infrared rays, it indicates that the top of the medicine grains in the medicine grain cavity 21 is below the medicine grain monitoring element 28, and the remaining amount of medicine grains in the medicine grain cavity 21 is small. At this time, the medicine grain reminder light 29 on the outer surface of the medicine grain barrel 2 lights up to remind the operator to replenish the medicine grains to ensure that the amount of medicine grains in the medicine grain cavity 21 remains sufficient.

[0039] After adopting the above structure, it needs to be further explained that a connecting plug 8 is provided on the outside of the medicine pellet barrel 2, and a connecting socket 14 matching the connecting plug 8 is provided on the top of the workbench 1 near the edge of the mounting hole 11. One side of the workbench 1 is usually connected to the power supply line through components such as wires and plugs to provide the driving mechanism 3 and the like with the necessary electrical energy for operation. The medicine pellet barrel 2 is inserted into the connecting socket 14 through the connecting plug 8, so that the medicine pellet monitoring element 28 in the medicine pellet barrel 2 and the medicine pellet indication light 29 on the surface are connected to the circuit inside the workbench 1, providing the medicine pellet monitoring element 28 and the medicine pellet indication light 29 with the necessary electrical energy for operation.

[0040] As one of the preferred embodiments of the present invention, Figure 1 , Figure 2 As shown, the inner diameter of the inner wall of the medicine pellet barrel 2 near the bottom gradually decreases and forms an inclined surface. The inclined surface formed on the inner wall of the medicine pellet barrel 2 can better guide the medicine pellets in the medicine pellet cavity 21 to the bottom and gather them, avoiding the medicine pellets inside being too loose. 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 on the inner wall of the conveying sleeve 4 can keep the width of the conveying cavity 41 consistent, avoiding a large gap between the conveying rotary plate 51 and the conveying cavity 41, causing the medicine pellets in the conveying cavity 41 to slide down along the gap.

[0041] In summary, the present invention is mainly used for dispensing and adjusting Chinese medicine granules. The rotating conveying ring 5 gradually transports the granules at the bottom of the conveying chamber 41 upward through a plurality of conveying rotary plates 51. The granules in the conveying chamber 41 overflow through the granule outlet 42 and are transported to the loading channel 12 to the loading tank 13. The granules are quantitatively dispensed and adjusted by setting the capacity. The pressure generated by the gravity of the granules in the granule chamber 21 will not act on the granules in the conveying chamber 41 in the vertical direction, and the amount of granules in the conveying chamber 41 will remain constant, so that the density of the granules in the conveying chamber 41 can remain stable, and the weight of the granules with the set capacity can remain stable, thereby improving the accuracy of the granule dispensing and adjustment amount.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
