Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of oral solution production, and more specifically, to a dispensing apparatus for oral solution production. Background Technology

[0002] Oral solutions, as a common pharmaceutical dosage form, rely heavily on the ingredient preparation process during production for product quality. As the pharmaceutical industry continues to demand higher standards for drug quality and production efficiency, the shortcomings of traditional oral solution preparation methods are becoming increasingly apparent.

[0003] Currently, most commercially available oral solution production equipment uses a centralized mixing system, which cannot separately mix different components or batches of materials in separate tanks. This method not only easily leads to cross-contamination between different materials, affecting drug quality, but also fails to meet the production needs of different formulations. Furthermore, after mixing, the transfer of materials is extremely inconvenient due to the unreasonable structural design of traditional equipment. It often requires the use of additional containers to transfer the solution a second time, increasing the complexity and cost of the production process. Moreover, material residue and spillage are prone to occur during the transfer process, resulting in material waste and environmental pollution.

[0004] Therefore, developing a dispensing device for oral solution production that can achieve separate mixing in separate tanks and facilitate material transfer is of great significance for improving the quality and efficiency of oral solution production and reducing production costs. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a dispensing device for oral solution production, which solves the technical problem that most oral solution dispensing devices in the prior art adopt a centralized mixing mode and cannot separately mix materials of different components or different batches in separate tanks.

[0006] According to one aspect, at least one embodiment of this disclosure provides a dispensing apparatus for producing oral solutions, comprising: A stand and a mixing tank, wherein the mixing tank is placed on the stand; A pair of upright plates and a positioning and stirring assembly, wherein the upright plates are disposed at both ends of the surface of the upright frame, and the positioning and stirring assembly is disposed on the upright plates; A pair of connecting frames and a feeding assembly, wherein the connecting frames are fixed to the top of the upright frame and the feeding assembly is disposed on the connecting frames and the upright frame; The feeding assembly includes a fixed base, which is located on the top of the upright frame. Several conveying pipes are installed inside the fixed base. Several metering pumps are installed on the upright frame. The output end of the metering pumps is connected to the conveying pipes. A centralized feeding box is connected to the connecting frame via a vertical linear drive.

[0007] As a further technical solution, a bent pipe is connected between one end of the conveying pipe and the centralized feeding box, a feeding port is provided at the top of the mixing tank, and an insert pipe is provided at the bottom of the centralized feeding box, with the insert pipe inserted into the feeding port.

[0008] As a further technical solution, the positioning stirring assembly includes a rectangular opening, which is formed on the side surface of the vertical plate. The vertical plates are connected by a top plate through a vertical linear drive, and the top plate is provided with a stirring frame driven by electricity.

[0009] As a further technical solution, the stirring rack is located in the mixing tank, and cylinders are provided on the side surfaces of the upright plate. A clamping frame is provided at the output end of the cylinder, and the clamping frame is attached to both sides of the surface of the mixing tank.

[0010] As a further technical solution, a pair of stabilizing rods are provided at both ends of the bottom of the top plate, and the stabilizing rods are movably fitted inside the vertical plate.

[0011] As a further technical solution, a positioning frame is provided on the surface of the upright frame. The positioning frame has an overall U-shaped structure and is wrapped around the outer wall of the mixing tank.

[0012] As a further technical solution, a pair of insertion slots are provided on the surface of the support frame.

[0013] As a further technical solution, a docking sleeve is provided on the bottom surface of the top plate, and the docking sleeve is fitted onto the top of the mixing tank.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the feeding assembly, through several conveying pipes within the fixed base and a metering pump on the upright frame, can quantitatively convey raw materials of different components. This solves the problem in existing centralized mixing modes that cannot handle individual mixing in separate tanks, avoids cross-contamination between different materials, and meets the production needs of different formulations. The centralized feeding box precisely connects to the inlet of the batching tank via a vertical linear drive device, and the insertion of the tube into the inlet forms a sealed connection, ensuring accurate injection of raw materials, reducing residue and spillage during material transfer, simplifying the production process, and lowering production costs.

[0017] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-5 As shown, it illustrates a dispensing apparatus for producing an oral solution according to an embodiment of the present disclosure, comprising: A support frame 1 and a mixing tank 2, wherein the mixing tank 2 is placed on the support frame 1; A pair of upright plates 3 and a positioning and stirring assembly 6, wherein the upright plates 3 are disposed at both ends of the surface of the upright frame 1, and the positioning and stirring assembly 6 is disposed on the upright plates 3; A pair of connecting frames 4 and a feeding assembly 5, wherein the connecting frames 4 are fixed to the top of the upright frame 1, and the feeding assembly 5 is disposed on the connecting frames 4 and the upright frame 1; The feeding assembly 5 includes a fixed base 5-1, which is located on the top of the upright frame 1. Several conveying pipes 5-2 are arranged inside the fixed base 5-1. Several metering pumps 5-3 are arranged on the upright frame 1. The output end of the metering pumps 5-3 is connected to the conveying pipes 5-2. A centralized feeding box 5-4 is connected to the connecting frame 4 through a vertical linear drive. A bent pipe 5-5 is connected between one end of the conveying pipe 5-2 and the centralized feeding box 5-4. A feeding port 5-6 is provided on the top of the mixing tank 2. An insertion tube 5-7 is provided on the bottom of the centralized feeding box 5-4. The insertion tube 5-7 is inserted into the feeding port 5-6.

[0024] In some examples, to achieve quantitative delivery and centralized injection of raw materials, a feeding assembly 5 is designed. This assembly includes a fixed base 5-1 mounted on top of the upright 1, and several integrated conveying pipes 5-2 corresponding to different types of raw materials. Each conveying pipe 5-2 is connected to the output end of a metering pump 5-3 on the upright 1. The metering pump 5-3 can adjust the raw material delivery rate according to a preset formula to ensure accurate raw material proportions injected into the mixing tank 2 each time. A vertical linear drive device (such as a cylinder 6-4 or an electric push rod) on the connecting frame 4 can drive the centralized feeding box 5-4 to move up and down. When feeding is required, the drive device pushes the centralized feeding box 5-4 down, so that the bottom insertion tube 5-7 is precisely inserted into the inlet 5-6 of the mixing tank 2, forming a sealed connection.

[0025] The bend in the pipe 5-5 between the conveying pipe 5-2 and the centralized feeding box 5-4 is made of a flexible material, such as silicone or rubber. This ensures smooth material transport while accommodating the lifting and lowering movement of the centralized feeding box 5-4, preventing pipe damage caused by rigid connections. For example, in the production of vitamin oral solutions, different types of vitamin raw materials, sweeteners, and solvents are each conveyed through their respective pipes 5-2, precisely metered by the metering pump 5-3, and then collected in the centralized feeding box 5-4. Finally, they are injected into the mixing tank 2 in one go through the insertion pipe 5-7. The entire process is highly automated, effectively avoiding errors from manual mixing and ensuring the stability of the composition of each batch of oral solutions.

[0026] like Figures 1-5 As shown in the figure, the positioning stirring assembly 6 in this embodiment includes a rectangular opening 6-1, which is opened on the side surface of the vertical plate 3. The vertical plates 3 are connected by a top plate 6-2 through a vertical linear drive. The top plate 6-2 is provided with an electrically driven stirring frame 6-3, which is located in the mixing tank 2. The side surface of the vertical plate 3 is provided with a cylinder 6-4, and the output end of the cylinder 6-4 is provided with a clamping frame 6-5, which is attached to both sides of the surface of the mixing tank 2.

[0027] In some examples, to achieve precise positioning and stable mixing of the mixing rack 6-3, a positioning mixing assembly 6 is designed. This assembly includes upright plates 3 positioned at both ends of the surface of the upright frame 1. Rectangular openings 6-1 on the side surfaces of the upright plates 3 provide guiding space for the lifting and lowering of the top plate 6-2. A vertical linear drive device (such as an electric push rod or telescopic cylinder 6-4) is connected to the top plate 6-2, allowing adjustment of the insertion depth of the mixing rack 6-3 according to the height of the mixing tank 2. The mixing rack 6-3 on the top plate 6-2 is driven to rotate by a motor. The shape and angle of its blades can create an efficient mixing flow field within the mixing tank 2, ensuring thorough and uniform mixing of the raw materials.

[0028] The output ends of the cylinders 6-4 on both sides of the upright plate 3 are connected to clamping frames 6-5. When the top plate 6-2 lowers the stirring frame 6-3 to a suitable position inside the mixing tank 2, the cylinders 6-4 push the clamping frames 6-5 inward, making them tightly fit against the two sides of the mixing tank 2. This mechanical clamping fixes the mixing tank 2, preventing the tank from shaking or shifting during stirring. This design ensures the stability of the stirring frame 6-3 during high-speed rotation, avoiding uneven stirring or liquid splashing caused by tank instability. For example, when mixing viscous syrup with other raw materials, the clamping frames 6-5 firmly fix the mixing tank 2, while the stirring frame 6-3 penetrates deep into the tank for high-intensity stirring, allowing raw materials of different viscosities to be mixed quickly and evenly, improving the production quality and efficiency of oral solutions.

[0029] For example, such as Figure 1 As shown, a pair of stabilizing rods 7 are provided at both ends of the bottom of the top plate 6-2, and the stabilizing rods 7 are movably fitted inside the vertical plate 3.

[0030] In some examples, a pair of stabilizing rods 7 at both ends of the bottom of the top plate 6-2 form a guide and positioning structure with the vertical plate 3. The stabilizing rods 7 are cylindrical and are movably fitted onto the top of the vertical plate 3 with a clearance fit. When the top plate 6-2 is raised and lowered by a vertical linear drive, the stabilizing rods 7 slide along the channels of the vertical plate 3, limiting the lateral displacement of the top plate 6-2. This design ensures that when the top plate 6-2 drives the stirring frame 6-3 to descend, the axis of the stirring frame 6-3 is coaxial with the center of the mixing tank 2, preventing the stirring paddle from eccentrically colliding with the tank wall due to the shaking of the top plate 6-2, thus improving the stirring positioning accuracy.

[0031] For example, such as Figure 1 As shown, a positioning frame 8 is provided on the surface of the upright frame 1. The positioning frame 8 has an overall U-shaped structure and is wrapped around the outer wall of the mixing tank 2.

[0032] In some examples, the U-shaped positioning frame 8 on the surface of the support 1 forms a semi-enclosed pre-fixed structure for the mixing tank 2. The opening wraps around the outer wall of the mixing tank 2, which can play a positioning role when the mixing tank 2 is put in, ensuring that the mixing tank 2 can be put into the accurate position in one go, saving adjustment time, and ensuring that the feeding tube 5-7 is precisely connected to the tank opening.

[0033] For example, such as Figure 1 As shown, a pair of insertion slots 9 are provided on the surface of the support frame 1.

[0034] In some examples, a pair of insertion slots 9 on the surface of the upright 1 are specifically designed for forklift loading. The insertion slots 9 have a rectangular through-type structure, with the width and depth adapted to the size of the forklift forks, and the edges of the slots are rounded to prevent scratches when the forklift is lifting. After the mixing tank 2 has finished mixing, the forklift forks can be directly inserted into the slots 9 to lift the upright 1 together with the mixing tank 2 as a whole. The rigid support surface of the insertion slots 9 bears the weight of the tank, avoiding tilting or falling that may occur if the mixing tank 2 is directly lifted.

[0035] The insertion slot 9 is positioned to correspond to the center of gravity of the ingredient tank 2, ensuring balance and stability during forklift handling. For example, the operator drives the forklift, aligns the forks with the insertion slot 9, and slowly pushes it in. Once the forks are fully inserted, the forklift can be lifted to transfer the ingredient tank 2 to the next process.

[0036] For example, such as Figure 5 As shown, a docking sleeve 10 is provided on the bottom surface of the top plate 6-2, and the docking sleeve 10 is fitted onto the top of the mixing tank 2.

[0037] In some examples, the mating sleeve 10 on the bottom surface of the top plate 6-2 forms a sealed positioning structure with the top of the mixing tank 2. Its inner diameter is interference-fitted with the outer diameter of the top of the mixing tank 2. When the top plate 6-2 descends, the mating sleeve 10 is fitted onto the outside of the tank opening, which not only prevents liquid splashing during stirring by sealing, but also ensures the coaxiality of the stirring frame 6-3 and the tank body by rigid fitting. For example, when stirring viscous solutions at high speed, the mating sleeve 10 can reduce the vibration transmitted from the top plate 6-2 to the tank body, while also helping to position the depth of the stirring blade, keeping the blade at a preset distance from the bottom of the tank and avoiding dead zones in the stirring.

[0038] In actual use: Place the mixing tank 2 in the positioning frame 8 of the upright frame 1, aligning the inlet 5-6 at the top of the mixing tank 2 with the insertion tube 5-7 at the bottom of the centralized feeding box 5-4. Activate the cylinder 6-4 on the side surface of the upright plate 3. The clamping frame 6-5 at the output end of the cylinder 6-4 will fit against both sides of the mixing tank 2 to fix it in place. According to the mixing requirements, adjust the raw material conveying volume of each conveying pipe 5-2 through the metering pump 5-3 on the upright frame 1. The raw material is collected in the centralized feeding box 5-4 through the bending pipe 5-5. Activate the vertical linear drive device on the connecting frame 4 to lower the centralized feeding box 5-4. Insert the insertion tube 5-7 into the inlet 5-6 of the mixing tank 2 to inject the raw material into the mixing tank 2. The positioning and mixing assembly 6 is activated. The vertical linear drive device between the upright plates 3 lowers the top plate 6-2. The docking sleeve 10 at the bottom of the top plate 6-2 is fitted onto the top of the mixing tank 2. The mixing frame 6-3 on the top plate 6-2 extends into the mixing tank 2. The electric drive rotates the mixing frame 6-3 to mix the raw materials in the mixing tank 2. After mixing is complete, the mixing frame 6-3 is closed. The vertical linear drive device raises the top plate 6-2, and the cylinder 6-4 retracts the clamping frame 6-5. The mixing tank 2 is then transferred to the next process using a forklift through the insertion slot 9 on the surface of the upright frame 1.
