Description

Technical Field

[0001] This invention belongs to the field of drug preparation technology, and particularly relates to a two-dimensional motion mixer for drug preparation. Background Technology

[0002] Drug preparation refers to the process of transforming active pharmaceutical ingredients (APIs) into a drug dosage form that is easy for patients to use through a series of specific technological processes. This process must strictly adhere to the regulations and standards for drug research and development, production, and quality management (such as Good Manufacturing Practices, GMP) to ensure the safety, efficacy, and quality stability of the drug.

[0003] Currently, in the actual operation of drug preparation, mixers are key equipment used to uniformly mix drug raw materials. Their core components include the tank body, the tank lid, and the mixing actuator. However, existing two-dimensional motion mixers have design flaws: for example, the sealing performance at the connection between the tank lid and the tank body is poor, making leakage problems very likely during long-term operation, which can adversely affect the quality of the drug inside the mixer.

[0004] In summary, existing two-dimensional motion mixers suffer from insufficient sealing performance at the connection between the tank and the lid, leading to easy contamination of the drugs. Utility Model Content

[0005] This invention provides a two-dimensional motion mixer for drug preparation, which can solve the problem of insufficient sealing performance at the connection between the tank and the lid in existing two-dimensional motion mixers, leading to easy contamination of the drug.

[0006] To achieve the above objectives, a two-dimensional motion mixer for drug preparation is provided according to an embodiment of the first aspect of the present invention, comprising a mixing tank and a tank cover disposed on the top surface of the mixing tank; the top surface of the mixing tank is provided with an installation notch;

[0007] Also includes:

[0008] A mixing assembly, comprising a mixing rod disposed inside a mixing tank and rotatably mounted on a tank cover, and a set of mixing blades disposed on the mixing rod;

[0009] A sealing assembly, comprising a rubber ring fixedly fitted onto the can lid and a rubber protrusion disposed within an installation notch.

[0010] A further improvement is that a DC servo motor is fixedly installed on the can lid, and the main shaft of the DC servo motor is connected to the mixing rod.

[0011] A further improvement is that a pair of cleaning scrapers are fixedly installed on the mixing rod, and each cleaning scraper is fixedly installed with a rubber cleaning blade that contacts the inner wall of the mixing tank.

[0012] A further improvement is that the rubber convex ring is divided into an inner section and an outer section, with the outer section fitting over the inner section.

[0013] A further improvement is that it also includes a connecting assembly, which includes several fixing posts fixedly installed on the outer side of the mixing tank, connecting seats fixedly installed on the fixing posts, and locking blocks fixedly installed on the inner side of each connecting seat.

[0014] A further improvement is that the outer surface of the can lid has a slot corresponding to each locking block, and the top and bottom surfaces of each slot extend out of the can lid.

[0015] A further improvement is that each of the connecting seats is provided with a fixing bolt, and each connecting seat is fixedly connected to the outside of the can lid by the fixing bolt.

[0016] A further improvement is that the mixing blades are fixedly installed on both sides of the mixing rod at equal intervals from top to bottom.

[0017] A further improvement is that the bottom surface of the mixing tank is provided with a discharge port, and an electric valve is fixedly installed on the discharge port.

[0018] A further improvement is that, after the can lid is placed within the installation notch, the outer wall of the rubber ring and the inner wall of the inner section of the rubber convex ring come into contact.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] (1) This utility model involves fitting the lid onto the mounting notch on the top surface of the mixing tank. Once the lid is in place, the outer wall of the rubber ring on the edge of the lid fits tightly against the inner wall of the inner section of the rubber convex ring on the inner side of the mounting notch. Through the cooperative design of the rubber ring and the rubber convex ring, the elastic properties of the rubber material can be used to enhance the sealing effect between the lid and the mixing tank, effectively preventing material leakage and ensuring the quality stability of drug production.

[0021] (2) This invention utilizes a DC servo motor, whose output shaft drives the mixing rod to rotate. The uniformly distributed mixing blades on the surface of the mixing rod rotate with the shaft, significantly reducing the risk of stratification of the drug material within the mixing tank and ensuring uniform mixing of all components. Simultaneously, the rotation of the mixing rod synchronously drives the cleaning scraper to rotate as well. The rubber cleaning blades on the cleaning scraper continuously scrape the inner wall of the mixing tank during rotation, effectively removing adhering material, thus avoiding raw material waste, maintaining the cleanliness of the equipment's inner wall, and significantly reducing the workload of subsequent maintenance.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] like Figures 1 to 3 As shown, a two-dimensional motion mixer for drug preparation includes a mixing tank 1 and a tank cover 11 disposed on the top surface of the mixing tank 1. A discharge port 12 is provided on the bottom surface of the mixing tank 1, and an electric valve 121 is fixedly disposed on the discharge port 12. An installation notch 101 is provided on the top surface of the mixing tank 1.

[0032] The mixing assembly 3 includes a mixing rod 32 disposed inside the mixing tank 1 and rotatably mounted on a tank cover 11, and a set of mixing blades 33 disposed on the mixing rod 32. The mixing blades 33 are fixedly installed on both sides of the mixing rod 32 at equal intervals from top to bottom. A DC servo motor 31 is fixedly mounted on the tank cover 11. The main shaft of the DC servo motor 31 is connected to the mixing rod 32. By starting the DC servo motor 31, the output shaft of the motor drives the mixing rod 32 to rotate. The mixing blades 33, which are evenly distributed on the surface of the mixing rod 32, rotate with the shaft to stir, which can significantly reduce the risk of stratification of the drug material in the mixing tank 1 and ensure that the components are mixed evenly.

[0033] As a preferred embodiment, a pair of cleaning scrapers 34 are fixedly installed on the mixing rod 32. Each cleaning scraper 34 is fixedly equipped with a rubber cleaning scraper 35 that contacts the inner wall of the mixing tank 1. The rotation of the mixing rod 32 synchronously drives the cleaning scraper 34 to rotate synchronously. The rubber cleaning scraper 35 on the cleaning scraper 34 continuously scrapes the inner wall of the mixing tank 1 during rotation, effectively removing the attached material, avoiding raw material waste, maintaining the cleanliness of the equipment's inner wall, and significantly reducing the workload of subsequent maintenance.

[0034] Sealing assembly 4 includes a rubber ring 41 fixedly fitted on the can lid 11 and a rubber protrusion 42 disposed in the mounting notch 101;

[0035] Specifically, the rubber ring 42 is divided into an inner section 401 and an outer section 402. The outer section 402 is fitted onto the inner section 401. After the can lid 11 is placed inside the installation notch 101, the outer wall of the rubber ring 41 and the inner wall of the inner section 401 of the rubber ring 42 come into contact. Through the matching design of the rubber ring 41 and the rubber ring 42, the elastic properties of the rubber material can be used to enhance the sealing effect between the can lid 11 and the mixing tank 1, effectively preventing material leakage and ensuring the quality stability of drug production.

[0036] like Figure 1 and Figure 3 As shown in this embodiment, another implementation scheme is also provided, as detailed below:

[0037] It also includes a connecting component 2, which includes several fixing posts 21 fixedly installed on the outer side of the mixing tank 1, connecting seats 22 fixedly installed on the fixing posts 21, and locking blocks 23 fixedly installed on the inner side of each connecting seat 22.

[0038] Specifically, the outer side of the can lid 11 is provided with a slot 102 at the position corresponding to each slot 23. The top and bottom surfaces of each slot 102 extend out of the can lid 11. By allowing the slot 23 on the inner side of the connecting seat 22 to slide and engage in the slot 102 on the outer side of the can lid 11, a preliminary limiting connection is achieved to prevent the can lid 11 from shaking.

[0039] Specifically, each connecting seat 22 is equipped with a fixing bolt, and each connecting seat 22 is externally fixedly connected to the can lid 11 through the fixing bolt, so as to facilitate the easy assembly and disassembly of the can lid 11.

[0040] like Figures 1 to 3As shown in this embodiment, it should also be noted that the actual dimensions of each component in the application document are selected and installed according to the actual needs on site. Additionally, it should be noted that this application document only addresses the shortcomings of existing two-dimensional motion mixers, such as insufficient sealing performance at the connection between the tank and the lid, leading to easy contamination of the drug; it does not cover other aspects. The working principle of this two-dimensional motion mixer for drug preparation is described below:

[0041] When using this novel solution, on-site personnel first place the drug raw materials into the mixing tank 1. Next, the tank lid 11 is placed over the mounting notch 101 on the top surface of the mixing tank 1, and the locking blocks 23 on the inner side of the connecting seat 22 are slidably engaged in the corresponding slots 102 on the outer side of the tank lid 11, achieving initial positioning and preventing the tank lid 11 from wobbling. Then, the connecting seat 22 and the tank lid 11 are connected using fixing bolts. Once the tank lid 11 is in place, the outer wall of the rubber ring 41 on the edge of the tank lid 11 tightly fits against the inner wall of the inner section 401 of the rubber protrusion 42 on the inner side of the mounting notch 101. Through the cooperative design of the rubber ring 41 and the rubber protrusion 42, the elastic properties of the rubber material enhance the sealing effect between the tank lid 11 and the mixing tank 1, effectively preventing material leakage and ensuring the stable quality of drug production.

[0042] Subsequently, the DC servo motor 31 is started, and the output shaft of the motor drives the mixing rod 32 to rotate. The mixing blades 33, which are evenly distributed on the surface of the mixing rod 32, rotate with the shaft to stir, which can significantly reduce the risk of stratification of the drug material in the mixing tank 1 and ensure that the components are mixed evenly. At the same time, the rotation of the mixing rod 32 synchronously drives the cleaning scraper 34 to rotate synchronously. The rubber cleaning scraper 35 set on the cleaning scraper 34 continuously scrapes the inner wall of the mixing tank 1 during rotation, effectively removing the attached material, avoiding raw material waste, maintaining the cleanliness of the inner wall of the equipment, and greatly reducing the workload of subsequent maintenance.

[0043] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
