Description

Technical Field

[0001] This utility model relates to the technical field of powder mixing equipment, specifically a powder mixing mechanism for effervescent tablet processing. Background Technology

[0002] Effervescent tablets, as an oral preparation that rapidly disintegrates upon contact with water, require the uniform mixing of various powders, including acid sources (such as citric acid and tartaric acid), alkali sources (such as sodium bicarbonate), active pharmaceutical ingredients, and excipients, during their production. Traditional mixing mechanisms achieve material mixing through the rotation of single-shaft or multi-shaft impellers. However, gaps exist between the impellers and the bottom of the container, causing denser components (such as sodium bicarbonate) to settle and become difficult to mix thoroughly. Furthermore, for materials with large density differences, axial or radial flow alone is insufficient to break up gravitational stratification, resulting in low mixing uniformity. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a powder mixing mechanism for effervescent tablet processing, which has the advantage of turning over the bottom material without dead corners, thus solving the problem of bottom material accumulation.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] A powder mixing mechanism for processing effervescent tablets includes a frame, a mixing tank fixedly connected to the frame, a stirring mechanism on the mixing tank, and a discharge component at the bottom of the mixing tank. The stirring mechanism includes a base plate fixedly connected to the bottom wall of the mixing tank, with arc-shaped grooves on both sides of the base plate extending to the outer side of the base plate in an arc shape. A connecting shaft one and a connecting shaft two are rotatably mounted on the mixing tank, and multiple guide plates are fixedly connected to both connecting shaft one and connecting shaft two for turning the material in the arc-shaped grooves.

[0006] Preferably, a bracket is fixedly connected to the mixing tank, a motor is fixedly mounted on the bracket, and a stirring rack is fixedly connected to the output end of the motor. The stirring rack is located inside the mixing tank.

[0007] Preferably, the first connecting shaft and the second connecting shaft are fitted with meshing spur gears, a drive shaft is rotatably mounted on the mixing tank, and bevel gears are fitted on the drive shaft and the output shaft of the motor. A belt assembly is provided between the second connecting shaft and the drive shaft.

[0008] Preferably, the discharge assembly includes a guide port opened in an arc-shaped groove, a sealing plate adapted to the guide port is slidably connected to the chassis, the sealing plate is arc-shaped, an electric telescopic rod is fixedly mounted on the frame, and both sealing plates are fixedly connected to the free end of the electric telescopic rod.

[0009] Preferably, the belt assembly includes pulleys fitted onto the connecting shaft and the drive shaft, and the pulleys are connected by belt drive.

[0010] Preferably, the outer wall of the guide plate is in contact with the inner wall of the arc groove, and the connecting shaft one and the adjacent arc groove are located at the same center, and the connecting shaft two and the adjacent arc groove are located at the same center.

[0011] By means of the above technical solution, this utility model provides a powder mixing mechanism for effervescent tablet processing, which has at least the following beneficial effects:

[0012] 1. The powder mixing mechanism for processing effervescent tablets has a material at the bottom of the mixing tank that gathers in the arc-shaped groove of the chassis. During stirring, connecting shaft one and connecting shaft two drive the guide plate to rotate, which can turn the material at the bottom of the mixing tank, forcing the bottom material to exchange with the upper material, which is beneficial to improving the mixing effect.

[0023] 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.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of the powder mixing mechanism for processing effervescent tablets provided by this utility model.

[0025] Example 1:

[0026] Ordinary stirring paddles often fail to reach the bottom of the container, causing denser components (such as sodium bicarbonate) to settle, creating mixing dead zones and resulting in inconsistent tablet disintegration times. To address these issues, a combination of... Figures 1-3 As shown, the powder mixing mechanism for processing effervescent tablets provided by this utility model includes a frame 100, a mixing tank 101 fixedly connected to the frame 100, a stirring mechanism 200 provided on the mixing tank 101, and a discharge component 300 provided at the bottom of the mixing tank 101.

[0027] Traditional mixing relies on axial or radial flow generated by blade rotation. Material mainly diffuses horizontally, with weak vertical convection. Material at the bottom needs to be passively dragged to rise slowly, resulting in long mixing cycles and high energy consumption. To address these issues, the mixing mechanism 200 includes a base 201 fixed to the bottom wall of the mixing tank 101. Arc-shaped grooves 206 are formed on both sides of the base 201, extending to the outer side of the base 201 in an arc shape. A connecting shaft is rotatably mounted on the mixing tank 101. Multiple guide plates 202 are fixedly connected to both connecting shaft 207 and connecting shaft 208, which are used to agitate the material in the arc-shaped groove 206. The material at the bottom of the mixing tank 101 will gather in the arc-shaped groove 206 of the chassis 201. During stirring, connecting shaft 207 and connecting shaft 208 drive the guide plates 202 to rotate, which can agitate the material at the bottom of the mixing tank 101, forcing the bottom material to exchange with the upper material, which is beneficial to improving the mixing effect.

[0028] Specifically, a bracket 204 is fixedly connected to the mixing tank 101, a motor 205 is fixedly mounted on the bracket 204, and a stirring frame 203 is fixedly connected to the output end of the motor 205. The stirring frame 203 is located inside the mixing tank 101. When the motor 205 is started, it drives the stirring frame 203 to rotate, and the stirring frame 203 stirs the materials inside the mixing tank 101.

[0029] Effervescent tablet powder often contains components with significant density differences (such as acids, alkalis, and fillers). If the bottom layer of material is not agitated for a long time, it can lead to uneven concentrations of components in certain areas, affecting the disintegration rate and uniformity of the finished product. To address this issue, connecting shaft 1 (207) and connecting shaft 2 (208) are fitted with meshing spur gears (210). A drive shaft (211) is rotatably mounted on the mixing tank (101). A bevel gear (209) is fitted onto the output shaft of the motor (205) and connecting shaft 2 (208). A belt assembly 212 is provided between 211. The output shaft of the motor 205 rotates, which drives the transmission shaft 211 to rotate through the bevel gear 209. The transmission shaft 211 drives the second connecting shaft 208 to rotate through the belt assembly 212. The second connecting shaft 208 drives the first connecting shaft 207 to rotate through the spur gear 210. The first connecting shaft 207 and the second connecting shaft 208 rotate in opposite directions, causing the guide plates 202 on both sides to generate opposing flows, forcing the material to converge and collide in the central area of ​​the arc-shaped groove 206, further improving the mixing effect.

[0030] The belt assembly 212 includes pulleys mounted on the connecting shaft 208 and the drive shaft 211. The pulleys are connected by belt drive. Using a single power source, multiple rotation modes can be achieved, which helps to reduce the operating cost of the equipment.

[0031] As can be seen from the embodiments, the arc-shaped grooves 206 on both sides of the chassis 201 naturally guide the bottom material to the working area of ​​the guide plate 202, avoiding deposition.

[0032] Example 2:

[0033] Combination Figure 3 and Figure 4 As shown, based on Embodiment 1, a guide port 301 is provided in the arc-shaped groove 206. A sealing plate 302 adapted to the guide port 301 is slidably connected on the chassis 201. The sealing plate 302 is arc-shaped. An electric telescopic rod 303 is fixed on the frame 100. Both sealing plates 302 are fixed to the free end of the electric telescopic rod 303. After mixing is completed, the two sealing plates 302 are linked by the same electric telescopic rod 303 to ensure that the guide ports 301 on both sides open synchronously. The material can be evenly discharged from both sides of the chassis 201, avoiding blockage or uneven flow rate caused by single-sided discharge, and improving unloading efficiency.

[0034] Specifically, the outer wall of the guide plate 202 is in contact with the inner wall of the arc groove 206, and the connecting shaft 1 207 and the adjacent arc groove 206 are located at the same center, and the connecting shaft 2 208 and the adjacent arc groove 206 are located at the same center.

[0035] As can be seen from the above embodiments: when the mixing device is running, the motor 205 starts and drives the stirring frame 203 to rotate, performing preliminary stirring of the material inside the mixing tank 101. At the same time, the output shaft of the motor 205 drives the transmission shaft 211 to rotate via the bevel gear 209. The transmission shaft 211 drives the connecting shaft 208 to rotate via the belt assembly 212. The connecting shaft 208 drives the connecting shaft 207 to rotate in the opposite direction via the meshing spur gear 210, causing the guide plates 202 on the connecting shaft 207 and the connecting shaft 208 to rotate respectively. The material rotates in opposite directions within the arc-shaped grooves 206 on both sides of the chassis 201, causing the material at the bottom of the mixing tank 101, which is gathered in the arc-shaped grooves 206, to be turned upwards. This material then flows upwards with the material in the middle and upper parts of the mixing tank 203, forming a confluence and achieving thorough mixing. After mixing is complete, the free end of the electric telescopic rod 303 retracts, causing the arc-shaped sealing plate 302 to slide outwards. This separates the sealing plate 302 from the guide port 301 in the arc-shaped groove 206, allowing the material to be discharged downwards through the guide port 301, thus completing the unloading process.

[0036] It should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
