[0002] Granules are a common oral solid dosage form for medicines, especially traditional Chinese medicines. Some antibiotics are unstable in water and can be made into granules. These granules are dissolved or suspended in water before use, such as amoxicillin granules and cephalexin granules. Granules require repackaging during processing or use.

[0003] In the prior art, such as in the publication number CN202096473U, a drug granule dispenser is disclosed. It includes a drug cylinder, in which evenly distributed rotatable partitions are provided. By controlling the opening and closing of the rotatable partitions, the drug granules in the drug cylinder can be evenly divided and the required number of portions can be poured out as needed.

[0004] Although the aforementioned patent has a reasonable structural design and ingenious concept, and is simple and convenient to operate, allowing family members of pediatric patients to quickly and accurately dispense granules of medication and improve dispensing efficiency, the granules tend to accumulate and cause blockages during dispensing, affecting the dispensing progress. Furthermore, it cannot dispense multiple times and cannot fix the bottle containing the medication, reducing the stability and efficiency of dispensing. Therefore, a dispensing device for granule production is proposed to address the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, such as the problem that drug granules accumulate and cause blockages during feeding, affecting the feeding progress, the inability to perform multiple fillings during dispensing, and the inability to secure the drug-containing bottles, thus reducing the stability and efficiency of dispensing, this utility model proposes a dispensing device for drug granule production.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A dispensing device for producing drug granules according to this utility model includes a base plate; a connecting frame is provided on one side of the top of the base plate, a square box is provided at one end of the connecting frame, a motor is provided on the front of the square box, the output end of the motor passes through the inside of the square box and is fixedly connected to a circular block, a number of semi-circular grooves are arranged in an annular array on the outer wall of the circular block, a material box is provided on one side of the square box, the bottom surface of the material box is inclined and a discharge trough is provided at the lower end, a feeding trough communicating with the discharge trough is provided on one side of the bottom of the square box, a trapezoidal box is provided at the bottom of the square box; a vibration component is provided on the inner wall of the trapezoidal box, a damping bearing is embedded on the other side of the top of the base plate, a turntable is sleeved inside the damping bearing, a number of circular holes are arranged in an annular array on the surface of the turntable, fixing holes are symmetrically provided at the four corners of the inner wall of the circular holes, an A spring is provided in the fixing hole, and a trapezoidal block is provided at one end of the A spring.

[0007] Preferably, the vibration assembly includes a U-shaped inclined plate, with B springs provided at the four corners of the top surface of the U-shaped inclined plate, a vibration plate provided on top of the B springs, and a vibration motor provided on the bottom surface of the vibration plate.

[0008] Preferably, the turntable is interference-fitted with the damping bearing, and the diameter of the circular slot matches the outer diameter of a standard medicine bottle.

[0009] Preferably, the width of the discharge trough of the material box is smaller than the diameter of the semi-circular groove, and the width of the feed trough is consistent with the arc length of the semi-circular groove.

[0010] Preferably, the cross-section of the trapezoidal box, which is wider at the top and narrower at the bottom, matches the inclination angle of the vibrating plate, and the width of the bottom outlet of the trapezoidal box is smaller than the diameter of the circular slot.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves quantitative dispensing of drug granules through a linkage structure design of a motor-driven circular block and a semi-circular groove. When the circular block rotates, the semi-circular groove scoops up granules at the discharge slot of the material box, and when it rotates to the bottom of the feed slot, it falls into the trapezoidal box by gravity, solving the problem of granule accumulation and blockage in traditional dispensers. The vibration component design of the U-shaped inclined plate, B-spring, and vibrating plate inside the trapezoidal box achieves the function of preventing granule accumulation and guiding them. The vibration motor drives the vibrating plate to vibrate at high frequency along the inclined direction, and the granules slide down into the circular slot of the turntable under the combined effect of gravity and vibration, solving the problem of uneven discharge caused by granule adhesion and improving the smoothness of material feeding.

[0014] 2. This utility model achieves a multi-station cyclic fixing function for medicine bottles through the interference fit structure design of the turntable and the damping bearing. The turntable can be rotated manually and positioned by damping force. The trapezoidal blocks symmetrically arranged at the four corners of the circular slot are elastically pressed against the outer wall of the medicine bottle by spring A, which solves the problem of bottle shaking or tipping during the dispensing process and improves the fixing stability.

Detailed Implementation

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figures 1-5 As shown, a dispensing device for producing drug granules includes a base plate 1; a connecting frame 2 is provided on one side of the top of the base plate 1, a square box 3 is provided at one end of the connecting frame 2, a motor 4 is provided on the front of the square box 3, the output end of the motor 4 passes through the inside of the square box 3 and is fixedly connected to a circular block 5, a number of semi-circular grooves 6 are arranged in a ring array on the outer wall of the circular block 5, a material box 7 is provided on one side of the square box 3, the bottom surface of the material box 7 is inclined and a discharge chute is provided at the lower end, a feeding chute 8 is provided on one side of the bottom of the square box 3 and communicates with the discharge chute, a trapezoidal box 9 is provided at the bottom of the square box 3; a vibration component 10 is provided on the inner wall of the trapezoidal box 9, a damping bearing 11 is embedded on the other side of the top of the base plate 1, a turntable 12 is sleeved inside the damping bearing 11, a number of circular hole grooves 13 are arranged in a ring array on the surface of the turntable 12, fixing holes are symmetrically provided at the four corners of the inner wall of the circular hole grooves 13, an A spring 14 is provided in the fixing hole, and a trapezoidal block 15 is provided at one end of the A spring 14.

[0024] During operation, the circular block 5 is driven to rotate by the motor 4. The annular semi-circular groove 6 on its outer wall scoops up the drug granules at the discharge slot of the material box 7. When the groove 6 rotates to the feed slot 8 at the bottom of the square box 3, the granules fall into the trapezoidal box 9 due to gravity. The vibration component 10 inside the trapezoidal box 9 guides the flow of granules through vibration to prevent accumulation. The turntable 12 is manually rotated and positioned by the damping bearing 11. The trapezoidal block 15 in the circular slot 13 elastically clamps the medicine bottle under the action of spring A 14, realizing continuous dispensing. The linkage design between the groove 6 and the material box 7 realizes quantitative transfer of granules, significantly improving dispensing accuracy. The turntable 12 and the damping bearing 11 work together to provide multi-station fixation, enhancing the smoothness of operation.

[0025] Furthermore, the vibration assembly 10 includes a U-shaped inclined plate 101, B springs 102 are provided at the four corners of the top surface of the U-shaped inclined plate 101, a vibration plate 103 is provided on the top of the B springs 102, and a vibration motor 104 is provided on the bottom surface of the vibration plate 103.

[0026] During operation, the U-shaped inclined plate 101 of the vibration assembly 10 supports the vibration plate 103 through the B spring 102. After the vibration motor 104 is started, it drives the vibration plate 103 to vibrate at high frequency. The particles slide down the surface of the vibration plate 103 to the bottom outlet of the trapezoidal box 9. The inclined vibration of the vibration plate 103 effectively solves the problem of particle adhesion and optimizes the uniformity of feeding.

[0027] Furthermore, the turntable 12 is interference-fitted with the damping bearing 11, and the diameter of the circular slot 13 matches the outer diameter of the standard medicine bottle.

[0028] During operation, the turntable 12 is interference-fitted with the damping bearing 11, allowing it to be stably stopped at any angle when manually rotated. The diameter of the circular slot 13 matches the outer diameter of a standard medicine bottle, ensuring the bottle is vertically positioned. The damping bearing 11 prevents the turntable 12 from accidentally shifting, enhancing the reliability of the dispensing process.

[0029] Furthermore, the width of the discharge chute of the material box 7 is smaller than the diameter of the semi-circular groove 6, and the width of the feed chute 8 is consistent with the arc length of the semi-circular groove 6.

[0030] During operation, the width of the discharge trough of the material box 7 is slightly smaller than the diameter of the groove 6, ensuring that the particles can only enter the groove 6 in a single layer; the width of the feed trough 8 is consistent with the arc length of the groove 6, so that the particles can completely detach from the groove 6 and fall down. The width control of the discharge trough avoids excessive scooping of particles, and improves the consistency of the dispensing amount.

[0031] Furthermore, the cross-section of the trapezoidal box 9, which is wider at the top and narrower at the bottom, matches the inclination angle of the vibrating plate 103, and the bottom outlet width of the trapezoidal box 9 is smaller than the diameter of the circular slot 13.

[0032] During operation, the upper wider and lower narrower cross section of the trapezoidal box 9 matches the tilt angle of the vibrating plate 103. When the particles slide under vibration, they are guided by the gradually narrowing cross section and fall to the bottom outlet. The outlet width is smaller than the diameter of the circular slot 13 to ensure accurate feeding.

[0033] Furthermore, the inclined surface of the trapezoidal block 15 is adapted to the curvature of the outer wall of the medicine bottle, and the compression stroke of spring A 14 is greater than 1 / 5 of the height of the medicine bottle;

[0034] During operation, the inclined surface of the trapezoidal block 15 fits against the outer wall of the medicine bottle. When the medicine bottle is inserted into the circular slot 13, it squeezes the trapezoidal block 15. The spring A 14 is compressed to generate a reverse elastic force to achieve adaptive clamping. The spring stroke covers different bottle height variations. The inclined surface curvature adapts to improve the clamping fit and enhances the stability of the bottle.

[0035] Working principle: The circular block 5 is driven to rotate by the motor 4. The semi-circular grooves 6 on its outer wall ring array scoop up the drug granules at the discharge slot of the material box 7 and transport them to the feed slot 8 as they rotate. The granules fall into the trapezoidal box 9 due to gravity and are guided to the bottom outlet by the coordinated vibration of the U-shaped inclined plate 101 and the vibrating plate 103 of the vibration component 10. At the same time, the turntable 12 is rotated and positioned by the damping bearing 11, so that the medicine bottle in the circular slot 13 accurately receives the falling granules under the elastic clamping of the spring A 14 and the trapezoidal block 15, realizing quantitative dispensing and multi-station cyclic operation.

[0036] The above are merely preferred embodiments of the present utility model and are 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, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
