Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging equipment technology, specifically a sealed dispensing device for raw pharmaceutical materials in aluminum drums. Background Technology

[0002] Currently, the structure of the automatic packaging machine for raw pharmaceutical materials in the drug dispensing station is such that the electromagnetic oscillating dispensing head does not contact the aluminum drum opening. Dispensing is done by pouring the material from the small opening of the electromagnetic oscillating dispensing head into the large opening of the aluminum drum. Because the powder is light, powder will be scattered during the dispensing process, easily falling outside the aluminum drum opening. After dispensing, the aluminum drum is sealed with an inner and outer lid. This powder scattered outside the aluminum drum opening will be distributed outside the sealed cavity. During transportation, the powder outside the sealed cavity will deteriorate. When used, the contaminated powder may fall into the aluminum drum when the lid is opened, potentially contaminating the qualified powder and affecting the quality of the drug. This is a significant contamination hazard.

[0003] There is no existing technology that can achieve a closed-loop packaging structure. A closed-loop packaging structure must not only achieve a closed-loop packaging process for the raw material to prevent the powder from scattering to the outside of the container, but also must not affect the packaging accuracy. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a sealed packaging device for raw pharmaceutical materials in aluminum drums.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A sealed dispensing device for raw pharmaceutical materials in aluminum drums includes a bellows, one upper end of which is connected to the dispensing head of a dispensing machine, and one lower end is fixedly connected to a discharge plug, which is a hollow annular structure. It also includes a lifting cylinder, the output end of which is connected to a lifting plate. A weighing sensor is fixedly mounted on the lifting plate. A mounting plate is provided above the weighing sensor, and a mounting plate is fixedly connected to the bottom of the mounting plate. Support plates are fixedly connected to both sides of the mounting plate, and multiple conveying rollers are rotatably connected between the two support plates. The weighing sensor is electrically connected to the dispensing machine control system, enabling precise dispensing.

[0006] In the above structure, the upper end of the corrugated pipe is connected to the dispensing head of the dispensing machine, and the lower end of the corrugated pipe is connected to the aluminum barrel opening through the feeding plug, so as to achieve a sealed connection with the barrel opening and thus achieve closed feeding and dispensing. Furthermore, the softness and elasticity of the corrugated pipe are used to counteract the influence of the electromagnetic vibration dispensing head on the symmetrical weight. In addition, the feeding plug and the corrugated pipe do not move up and down. The lifting cylinder drives the aluminum barrel to move up and down to realize the insertion and disengagement of the barrel opening and the feeding plug, reducing the secondary scattering of residual powder in the corrugated pipe after dispensing.

[0007] A first bidirectional telescopic power mechanism is fixedly connected to the mounting plate. Each of the two output ends of the first bidirectional telescopic power mechanism is fixedly connected to a vertical plate. The vertical plate extends from between the two conveying rollers to the top and is connected to an aluminum barrel positioning gripper. The two aluminum barrel positioning grippers operate simultaneously to limit the outer surface of the aluminum barrel, thereby ensuring accurate alignment between the aluminum barrel and the discharge plug.

[0008] The first bidirectional telescopic power mechanism uses a bidirectional cylinder.

[0009] The mounting plate is an inverted U-shaped structure, and the weighing sensor is installed inside the opening of the U-shaped structure.

[0010] Two fixed grippers are provided on the outer side of the feeding plug, and the two fixed grippers are respectively connected to the two output ends of the second bidirectional telescopic power mechanism. The second bidirectional telescopic power mechanism is fixedly installed, and during docking, the feeding plug is fixed by the fixed grippers to achieve accurate positioning of the sealing port.

[0011] The second bidirectional telescopic power mechanism uses a bidirectional cylinder.

[0012] Both the bellows and the feeding stopper are made of silicone.

[0013] The lower outer surface of the feeding plug is set as a conical surface.

[0014] The beneficial effects achieved by this utility model are: This invention connects the feeding plug under the corrugated tube to the aluminum barrel opening, thereby sealing the aluminum barrel opening during the dispensing operation and preventing the powder from scattering. In addition, the corrugated tube connects to the dispensing head, and the softness and elasticity of the silicone corrugated tube are used to counteract the effect of electromagnetic vibration on the weight of the dispensing head. This utility model achieves accurate positioning of the sealing opening by fixing the feeding plug with a fixed clamp. The feeding stopper and corrugated pipe of this utility model do not rise or fall, but the aluminum bucket rises or falls to achieve the insertion and disengagement of the bucket opening and the feeding stopper, thereby reducing the secondary scattering of residual powder in the corrugated pipe after dispensing. This utility model has a compact structure, stable operation, and accurate positioning, making it suitable for the closed packaging needs of aluminum drum packaging production lines of various specifications.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] Example: like Figures 1-4 As shown, a sealed dispensing device for raw pharmaceutical materials in aluminum drums includes a bellows 1. One upper end of the bellows 1 is connected to the electromagnetic oscillating dispensing head of a dispensing machine via a clamp, and the lower end is fixedly connected to a discharge stopper 2, which is a hollow annular structure. Both the bellows 1 and the discharge stopper 2 are made of silicone material, and the lower outer surface of the discharge stopper 2 is tapered.

[0019] The sealed packaging device for raw material aluminum drums also includes a lifting cylinder 8, which is fixedly installed. A lifting plate 7 is connected to the output end of the lifting cylinder 8. A weighing module is fixedly installed on the lifting plate 7, and a weighing sensor 15 is installed on the weighing module. A mounting plate 14 is installed above the weighing sensor 15. A mounting plate 10 is fixedly connected to the bottom of the mounting plate 14, and support plates 6 are fixedly connected to both sides of the mounting plate 10. Multiple conveying rollers 11 are rotatably connected between the two support plates 6. When the lifting plate 7 and the weighing sensor 15 rise under the action of the lifting cylinder 8, they can drive the mounting plate 14 to rise. The mounting plate 14 then drives the mounting plate 10, support plates 6, conveying rollers 11, and the aluminum drum 3 above them to rise, thus achieving docking of the opening of the aluminum drum 3 with the discharge plug 2.

[0020] The weighing sensor 15 is electrically connected to the dispensing machine control system, enabling precise dispensing.

[0021] A first bidirectional telescopic power mechanism 9 is fixedly connected to the mounting plate 10. Two output ends of the first bidirectional telescopic power mechanism 9 are respectively fixedly connected to vertical plates 5. The vertical plates 5 extend from between the two conveying rollers 11 to the upper part and are connected to aluminum barrel positioning grippers 4. The aluminum barrel positioning grippers 4 have three contact surfaces (one vertical surface and two symmetrical inclined surfaces) that contact the outer wall of the aluminum barrel 3. The two aluminum barrel positioning grippers 4 operate simultaneously to position the aluminum barrel 3, ensuring accurate alignment between the aluminum barrel 3 and the discharge plug 2.

[0022] The first bidirectional telescopic power mechanism 9 is a bidirectional cylinder.

[0023] The mounting plate 14 is an inverted U-shaped structure, and the weighing sensor 15 is installed inside the opening of the U-shaped structure. When the weighing sensor 15 rises, it can drive the mounting plate 14 to rise.

[0024] Two fixed grippers 12 are provided on the outer side of the feeding plug 2, and the two fixed grippers 12 are respectively connected to the two output ends of the second bidirectional telescopic power mechanism 13. The second bidirectional telescopic power mechanism 13 is fixedly installed, and during docking, the feeding plug 2 is fixed by the fixed grippers 12 to achieve accurate positioning of the sealing opening. The second bidirectional telescopic power mechanism 13 is a bidirectional cylinder.

[0025] The working principle and operation process of this utility model are as follows: The upper part of the silicone corrugated tube 1 is connected to the electromagnetic vibration dispensing port via a clamp, and the lower part is connected to the feeding plug 2. The position of the feeding plug 2 is fixed by the fixing clamp 12. The aluminum drum 3 is conveyed to the dispensing station via the conveying roller 11. Two aluminum drum positioning clamps 4 clamp the aluminum drum 3 to accurately position and clamp it. The lifting cylinder 8 rises, lifting the aluminum drum 3 so that the feeding plug 2 and the mouth of the aluminum drum 3 are tightly inserted. After the connection is completed, the fixing clamp 12 is released, the dispensing machine receives a signal, starts the dispensing program, and completes the material dispensing by weighing sensor 15. After dispensing is completed, the fixing clamp 12 clamps the feeding plug 2, the output end of the lifting cylinder 8 falls, and the mouth of the drum is separated from the feeding plug 2. The conveying roller 11 conveys the aluminum drum 3 to the next station for plugging and capping, completing one sealed dispensing process. At least one of the conveying rollers 11 is an electric roller, that is, the motor is set inside the roller and can realize automatic rotation.
