Description

Technical Field

[0001] This utility model relates to the field of measuring bucket technology, and in particular to a measuring bucket for a pediatric granule dosage adjustable dispensing machine. Background Technology

[0002] Pediatric granules are oral solid dosage forms specifically designed for children. They are typically made by mixing the medication with appropriate excipients and then forming them into granules, which are suitable for children's weaker swallowing abilities. During the preparation of pediatric granules, a dispensing machine is usually used for dispensing. The dispensing machine's measuring hopper is the core component, which mainly ensures that the dosage of each dispensing meets the strict standards for children's medication by precisely controlling the volume of the granules, thus avoiding medication safety issues caused by inaccurate dosage.

[0003] Existing dispensing machines mostly use a graded dosage adjustment mechanism in their metering hoppers. The dosage can be adjusted by changing the metering discs of different sizes. This method cannot control the size of the feed hole in real time, and the adjustment accuracy is limited, making it difficult to meet the dispensing requirements of small doses and high precision for pediatric granules. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a metering hopper for an adjustable dosage dispensing machine for pediatric granules, which aims to improve the problem that existing metering hoppers cannot control the size of the feed hole in real time, resulting in low metering accuracy.

[0006] The above technical solution allows the granules in the feeding hopper to remain in a flowing state by rotating the feeding rod driven by a motor, preventing clumping or accumulation and ensuring that the granules fall evenly.

[0007] As a further description of the above technical solution: the discharge mechanism includes a cylinder, which is fixedly connected to a connecting plate. A sealing cover is fixedly connected to the right end of the cylinder. A discharge hole is opened on the surface of the connecting plate. A first hollow ring is attached to the inner wall of the discharge hole. The top of the first hollow ring is threadedly connected to the inner wall of the rotating disk.

[0008] The above technical solution concentrates the metering function in the first hollow ring, enabling the equipment to adapt to production tasks with different dosage requirements by replacing different first hollow rings.

[0009] As a further description of the above technical solution: the discharge mechanism includes two support columns, both of which are fixedly connected to the fixed frame, and a second hollow ring and a third hollow ring are respectively attached to the surface of the two support columns;

[0010] The above technical solution involves installing an anti-slip rubber pad at the top of the support column, which increases the friction between the support column and the hollow ring.

[0011] As a further description of the above technical solution: the bottom surface of the feeding rod is in contact with the inner wall of the feeding bin, and a photoelectric sensor is fixedly connected to the bottom inner wall of the feeding rod;

[0012] Through the above technical solution, the photoelectric sensor achieves precise opening and closing of the feed port through automated control, ensuring the accuracy of the dispensing dosage.

[0013] As a further description of the above technical solution: the inner wall of the driven member is rotatably connected to the outer wall of the rotating disk, and a sliding hole is provided on the surface of the rotating disk, and the inner wall of the sliding hole is slidably connected to the bottom surface of the driven member;

[0014] The above technical solution allows the driven component to optimize the size of the feed hole according to the granule flow rate adjustment requirements through the combined action of the sliding hole and the moving groove.

[0015] As a further description of the above technical solution: the bottom end of the limiting rod is threaded with a connecting nut, and the left end of the second cylinder is fixedly connected with a ring, which is sleeved on the top surface of the limiting rod;

[0016] The above technical solution enables the equipment to accurately control the rotation angle of the rotating disc through a cylinder, thereby achieving precise adjustment of the feed hole size and ensuring the accuracy and consistency of the granule dispensing dosage.

[0017] As a further description of the above technical solution: a discharge pipe is fixedly connected to the bottom of the discharge hole, and the bottom surface of the first hollow ring is in contact with the top surface of the discharge pipe;

[0018] The above technical solution, through the design of the first hollow ring fitting snugly with the discharge pipe, eliminates the possible area of ​​material residue, which better meets the strict cleanliness requirements of pharmaceutical equipment.

[0019] As a further description of the above technical solution: the sealing cover is slidably connected to the inner wall of the connecting plate, and the sealing cover is in contact with the inner wall of the discharge hole;

[0020] The above technical solution enables rapid sealing and opening of the discharge port through a cylinder and a sealing cap, thereby improving the accuracy of granule dispensing.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, through the combined action of the driven member, the moving groove and the sliding hole, the driven member can control the size of the feed hole. When the dosage requirement is small, the cylinder two controls the limit rod to drive the rotating disk to rotate so that the driven member covers part of the feed hole, thereby controlling the amount of granules passing through and achieving better metering accuracy.

[0023] 2. In this utility model, the first hollow ring is threadedly connected to the rotating disk, and the first hollow ring can move downward a certain distance so that the top thread is dislodged from the inside of the rotating disk.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] Reference Figure 1 and Figure 4 An embodiment of this utility model provides a metering hopper for an adjustable dosage dispensing machine for pediatric granules, comprising a fixed frame 1, a feeding bin 2 fixedly connected to the top of the fixed frame 1, a motor 3 fixedly connected to the top of the inner wall of the feeding bin 2, a feeding lever 4 fixedly provided at the output end of the motor 3, a fixed plate 6 fixedly connected to the bottom of the fixed frame 1, a moving groove 7 opened at the bottom of the fixed plate 6, a driven member 8 slidably connected to the inner wall of the moving groove 7, a rotating disk 9 attached to the bottom of the driven member 8, a limit rod 17 rotatably connected to the left inner wall of the rotating disk 9, a cylinder 18 fixedly connected to the bottom of the fixed frame 1, a connecting plate 11 fixedly connected to the bottom of the fixed frame 1, and a discharge mechanism at the top of the connecting plate 11;

[0034] Specifically, a ring is fixed to the top of the piston inside cylinder 2 18. The inner diameter of the ring is larger than the diameter of the limiting rod 17 and is sleeved on the top of the limiting rod 17, so that the limiting rod 17 can be displaced when the piston inside cylinder 2 18 extends, thereby driving the rotating disk 9 to rotate. When the rotating disk 9 rotates, the driven member 8 will slide in the moving groove 7, thereby changing the size of the feed hole.

[0035] Reference Figure 2 and Figure 3 The discharge mechanism includes a cylinder 12, which is fixedly connected to a connecting plate 11. A sealing cover 13 is fixedly connected to the right end of the cylinder 12. A discharge hole 14 is opened on the surface of the connecting plate 11. A first hollow ring 10 is attached to the inner wall of the discharge hole 14. The top of the first hollow ring 10 is threadedly connected to the inner wall of the rotating disk 9.

[0036] Specifically, the first hollow ring 10, as the metering unit that directly contacts the material, has a threaded connection with the rotating disk 9 that ensures connection stability and provides convenience for quick replacement. When it is necessary to adjust the dispensing dosage, simply unscrew the first hollow ring 10 and replace it with a module of different specifications to adjust the discharge volume, thereby improving the adaptability and flexibility of the equipment.

[0037] Reference Figure 2 The bottom surface of the feeding rod 4 is in contact with the inner wall of the feeding bin 2, and a photoelectric sensor 5 is fixedly connected to the bottom inner wall of the feeding rod 4.

[0038] Specifically, when the feeding rod 4 rotates under the drive of the motor 3, its bottom edge maintains a constant small distance from the inner wall of the feeding bin 2. This effectively agitates the accumulated granules, breaks up material bridging, and avoids mechanical wear caused by rigid contact. The detection end of the photoelectric sensor 5 is aligned with the top opening of the first hollow ring 10. When the granules are filled into the first hollow ring 10, the infrared beam emitted by the sensor's transmitting end is blocked by the material. The signal at the receiving end changes and is converted into an electrical signal, which is then transmitted to the control system.

[0039] Reference Figure 3 The inner wall of the driven member 8 is rotatably connected to the outer wall of the rotating disk 9. A sliding hole 15 is provided on the surface of the rotating disk 9, and the inner wall of the sliding hole 15 is slidably connected to the bottom surface of the driven member 8.

[0040] Specifically, the control system controls the rotation angle of the rotating disk 9 according to the preset dosage to accurately control the size of the feed hole. When the cylinder 18 drives the limit rod 17 to rotate the rotating disk 9, the driven part 8 slides radially under the constraint of the sliding hole 15. Multiple driven parts 8 move synchronously to form a structure similar to an aperture shutter, so as to realize the continuous adjustment of the feed hole area, thereby achieving higher precision dosage control and meeting the dispensing requirements of different specifications of granules.

[0041] Reference Figure 4 The bottom end of the limiting rod 17 is threaded with a connecting nut 19, and the left end of the cylinder 18 is fixedly connected with a ring, which is sleeved on the top surface of the limiting rod 17.

[0042] Specifically, the limiting rod 17 and the rotating disk 9 are detachably connected by a threaded pair, and the ring at the left end of the cylinder 2 18 is sleeved on the top of the limiting rod 17 to ensure that the driving force of the cylinder 2 18 can be transmitted to the rotating disk 9.

[0043] Reference Figure 2 and Figure 3 The bottom of the discharge hole 14 is fixedly connected to the discharge pipe 20, and the bottom surface of the first hollow ring 10 is in contact with the top surface of the discharge pipe 20.

[0044] Specifically, the discharge pipe 20 and the first hollow ring 10 form a stable material conveying channel. The contact surface between the two adopts a planar sealing structure. The axial center line of the discharge pipe 20 coincides with the center line of the discharge port of the first hollow ring 10, so as to avoid the material from flowing out of the channel during discharge and ensure the consistency of the dispensing dosage.

[0045] Reference Figure 3 The sealing cover 13 is slidably connected to the inner wall of the connecting plate 11, and the sealing cover 13 is in contact with the inner wall of the discharge hole 14;

[0046] Specifically, the inner wall of the connecting plate 11 is provided with dovetail-shaped protrusions, and the two sides of the sealing cover 13 are embedded in the dovetail-shaped protrusions of the inner wall of the connecting plate 11, forming a constraint relationship that can both slide smoothly and prevent lateral displacement. When the cylinder 12 drives the sealing cover 13 to move, the sealing cover 13 and the edge of the discharge hole 14 form a sealing surface to avoid the leakage of granules and affect the accuracy of dispensing.

[0047] Example 2:

[0048] Reference Figure 5 The discharge mechanism includes two support columns 16, both of which are fixedly connected to the fixed frame 1. The surfaces of the two support columns 16 are respectively fitted with a second hollow ring 21 and a third hollow ring 22.

[0049] Specifically, the support column 16 is made of stainless steel. The support column 16 forms a support structure for the hollow ring through multi-point contact, preventing the hollow ring from tilting or shaking during placement. After the first hollow ring 10 is removed and its interior is cleaned, the first hollow ring 10 is supported by the support column 16 to facilitate the drying of the surface moisture of the first hollow ring 10. At the same time, the support column 16 supports hollow rings of different specifications, such as the second hollow ring 21 and the third hollow ring 22, so that operators can quickly select the corresponding module according to production needs and shorten the equipment changeover time.

[0050] Working principle: Since the first hollow ring 10 is threadedly connected to the rotating disk 9, and the outer diameter of the first hollow ring 10 is slightly smaller than the inner diameter of the discharge hole 14, while the inner diameter of the discharge pipe 20 is slightly larger than the inner diameter of the discharge hole 14, when the first hollow ring 10 is rotated, the first hollow ring 10 can move downward a certain distance so that the top thread comes out of the rotating disk 9, thereby allowing the metering hopper to adjust the discharge volume of granules by replacing the first hollow ring 10 of different specifications;

[0051] On the other hand, the metering hopper uses photoelectric sensor 5 to determine whether the inside of the first hollow ring 10 is filled with granules. It controls the limit rod 17 to move and close the top inlet hole of the first hollow ring 10 through cylinder 2 18, and controls the sealing cover 13 to slide out quickly from the top of the outlet hole 14 through cylinder 1 12 so that the granules fall into the outlet pipe 20 for dispensing the granules.

[0052] In addition, the movable groove 7 on the top of the fixed plate 6 is a hexagonal groove, and each follower 8 has a protrusion on its top that fits the movable groove 7. At the same time, the movement range of the follower 8 is limited by the sliding connection between the bottom of the follower 8 and the sliding hole 15, so that each follower 8 can slide along one side of the hexagon. The adjustability of the feed hole is realized by the principle similar to the aperture shutter. When the dosage requirement is small, the cylinder 2 18 controls the limit rod 17 to drive the rotating plate 9 to rotate so that the follower 8 covers part of the feed hole, thereby controlling the amount of granules passing through and achieving better metering accuracy.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
