[0002] Granules are dry, granular preparations of a specific particle size, formed by mixing the API with appropriate excipients. Some antibiotics, such as amoxicillin granules and cephalexin granules, are unstable in water and can be prepared as granules. These granules are then dissolved or suspended in water before use. Granules are also a common dosage form for children.
[0003] In the existing granular drug production, it is necessary to pass powders or granules of multiple raw materials into the interior of a mixing drum for thorough mixing and stirring, and then the mixed raw materials are processed in the next step. However, the existing drug powder mixing method is mostly to mix the drug powder or granules by rotating a stirring rod driven by a motor. Due to this mixing method, the drug particles are small and the stirring rod is suspended inside the mixing drum. Therefore, the drug may accumulate at the bottom of the mixing drum, resulting in uneven mixing of the drug, thereby affecting the production quality of the drug. Therefore, a mixing equipment for granular drug production is urgently needed to improve this problem. Utility Model Content

[0021] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.
[0022] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.
[0023] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.
[0024] like Figures 1 to 4 The main structure of a mixing device for granular drug production shown in the figure is composed of a hollow tray 6 for drug mixing and a base plate 1 for mounting the mixing device for granular drug production. A mixing drum 2 is fixedly connected to the top surface of the base plate 1. A plurality of feed pipes 3 are fixedly connected to the top surface of the mixing drum 2. Sealing doors are installed on the top surfaces of the two feed pipes 3 to prevent the drug raw material powder from being ejected through the feed pipes 3.
[0025] The top surface of the mixing cylinder 2 is provided with an air outlet 4, and the inner wall of the air outlet 4 provided on the top surface of the mixing cylinder 2 is fixedly connected with a blocking net 14. Thanks to the setting of the blocking net 14 on the inner wall of the air outlet 4, the medicine can be effectively blocked from entering the interior of the mixing cylinder 2 without affecting the discharge of gas.
[0026] A circular groove 5 is formed on the top surface of the bottom plate 1. A hollow disk 6 is rotatably connected to the inside of the circular groove 5. A plurality of air outlet pipes 11 are fixedly connected to the top surface of the hollow disk 6. A one-way valve 12 is fixedly installed inside each of the plurality of air outlet pipes 11 fixedly connected to the top surface of the hollow disk 6. Thanks to the arrangement of the one-way valve 12 in the air outlet pipe 11, the pharmaceutical raw materials inside the mixing cylinder 2 can be effectively prevented from entering the interior of the hollow disk 6 through the air outlet pipe 11.
[0027] A motor 7 is fixedly connected to the bottom of the circular groove 5, and a rotating tube 8 is connected and fixed between the rotating shaft of the motor 7 and the hollow disk 6. A sleeve 9 is rotatably sleeved on the outer wall of the rotating tube 8, and a bearing and a sealing ring are symmetrically rotatably sleeved between the inner wall of the sleeve 9 and the outer wall of the rotating tube 8, and the sealing ring is located on the outside of the bearing to prevent the gas inside the sleeve 9 from leaking to the outside. The hollow disk 6 blows air into the interior of the mixing barrel 2 while rotating, so that the raw materials in the mixing barrel 2 can be evenly blown up, thereby fully mixing the medicines, thereby preventing the raw materials from accumulating at the lower end of the interior of the mixing barrel 2;
[0028] An air inlet hole is opened on the wall of the rotating tube 8, and the air inlet hole is located at the socket of the sleeve 9. The outside of the sleeve 9 is connected and fixedly connected to the gas pipe 10, and the gas pipe 10 extends to the outside of the bottom plate 1. Because an air inlet hole is opened on the side wall of the rotating tube 8, and the air inlet hole is located at the socket of the sleeve 9, the gas in the sleeve 9 will enter the interior of the rotating tube 8 and the hollow disk 6.
[0029] Two arc blocks 13 are symmetrically fixedly connected to the lower end of the hollow disk 6, and an annular groove is opened at the lower end of the inner part of the circular groove 5. The two arc blocks 13 fixedly connected to the lower end of the hollow disk 6 are respectively slidably connected to the inside of the annular groove opened at the lower end of the inner part of the circular groove 5. Thanks to the two arc blocks 13 fixedly connected to the lower end of the hollow disk 6 being respectively slidably connected to the inside of the annular groove opened at the lower end of the inner part of the circular groove 5, the rotation of the hollow disk 6 can be effectively limited, and the stability of the hollow disk 6 during rotation can be further improved.
[0030] A rubber sealing ring 15 is fixedly mounted on the outer wall of the hollow disk 6. The outer wall of the rubber sealing ring 15 on the outer wall of the hollow disk 6 slides and fits tightly against the inner wall of the circular groove 5. Thanks to the setting of the rubber sealing ring 15, the pharmaceutical raw materials inside the mixing barrel 2 can be prevented from entering the interior of the circular groove 5 through the gap between the hollow disk 6 and the circular groove 5.
[0031] How it works
[0032] The mixing equipment for producing granular medicines, when in use, first, a variety of raw materials for producing granular medicines are introduced into the interior of the mixing drum 2 through the two feeding pipes 3 on the top surface of the mixing drum 2, then the motor 7 is started, and the motor 7 drives the rotating pipe 8 fixedly connected to the end of its rotating shaft and the hollow disk 6 fixedly connected to the upper end of the rotating pipe 8 to rotate, and at the same time, the air supply pipe 10 is connected to an external air source, and the gas is introduced into the interior of the sleeve 9 connected to the end of the air supply pipe 10. At this time, since an air inlet hole is opened on the side wall of the rotating pipe 8, and the air inlet hole is located at the sleeve connection of the sleeve 9, the gas in the sleeve 9 will enter the interior of the rotating pipe 8 and the hollow disk 6, and then be blown into the interior of the mixing drum 2 through the multiple air outlet pipes 11 fixedly connected to the top surface of the hollow disk 6, so that the medicine powder or small particle raw materials in the mixing drum 2 are blown up, and the hollow disk 6 blows air into the interior of the mixing drum 2 while rotating, so that the raw materials in the mixing drum 2 can be evenly blown up, thereby fully mixing the medicines, and thus preventing the raw materials from accumulating at the lower end of the interior of the mixing drum 2.
