Description

Technical Field

[0001] This utility model belongs to the technical field of pharmaceutical production, and in particular to a stirring device for processing pharmaceutical tablets. Background Technology

[0002] Drugs are substances that can be used to treat, prevent, and diagnose diseases by altering the physiological, biochemical, and pathological states of the human body, and which are specified with indications or functions, usage, and dosage. Drug production refers to the process of processing raw materials into drugs that can be used for medical purposes. Most existing drugs are processed into tablets. Before processing, the drug powder needs to be mixed and then water is added and stirred to increase the viscosity of the drug powder, which facilitates subsequent tablet making.

[0003] The existing mixing method involves directly pouring water into the powder, which easily causes the powder to clump together, affecting the mixing effect and subsequent tablet making. During mixing, the powder mixture tends to stick to the inner wall of the container, which can lead to corrosion of the container's inner wall over time and also results in powder waste.

[0016] Working principle: This device is equipped with an external power supply to power drive motor 1 (2-3-1) and drive motor 2 (3-1). Both drive motor 1 (2-3-1) and drive motor 2 (3-1) are existing technologies and are purchased externally, so they will not be described in detail.

[0017] During use, place the powder to be mixed into the mixing tank 1, then place the lid 2-1 on top of the mixing tank 1 and secure it with bolts. The lid 2-1 prevents impurities from entering during mixing and also prevents dust from polluting the working environment. Connect the water pipe to the inlet 2-2-8, allowing water to enter the spray pipe 2-2-1 through the inlet 2-2-8. The water is blocked by the sealing plug 2-2-5. Power on the drive motor 3-1, which drives the rotating shaft 3-2. The L-shaped scraper 3-3 and stirring rod 3-4 rotate. The rotation of stirring rod 3-4 can stir the powder, and at the same time, the L-shaped scraper 3-3 can clean the inner wall and bottom of the mixing tank 1 to prevent the powder from sticking to the wall. The drive motor 2-3-1 is powered on, which drives the push plate 2-3-2 to rotate. The rotation of push plate 2-3-2 pushes the linkage rod 2-3-4 to rotate around the fixed plate 2-3-3. The linkage rod 2-3-4 presses down on the round head 2-2-7, thereby compressing the spring 2-2-6. The movement of guide post 2-2-4 causes sealing plug 2-2-5 to move downwards, separating it from the bottom surface of spray pipe 2-2-1 and creating a gap. Water inside spray pipe 2-2-1 flows out through this gap and falls onto the horizontal convex edge 2-2-3. The water flowing along the horizontal convex edge 2-2-3 increases the area over which the water falls, preventing the water from concentrating and causing the powder to clump together. The water falling onto the powder effectively adds moisture to it. The movement of guide post 2-2-4 causes sealing plug 2-2-5 to slide. The sealing plug 2-2-5 prevents water from flowing out through the top surface of the spray pipe 2-2-1. When the push plate 2-3-2 rotates from its highest point downwards, the spring 2-2-6 causes the round head 2-2-7 to reset, which in turn resets the sealing plug 2-2-5. At this time, no water flows out of the spray pipe 2-2-1. The drive motor 2-3-1 drives the push plate 2-3-2 to rotate continuously, achieving intermittent water addition to the powder, avoiding excessive water addition at one time, which would cause the powder to clump and affect the mixing effect. After mixing is complete, the power is turned off, and the discharge valve can be opened to remove the mixed powder. An acrylic observation window can be installed on the outer wall of the mixing tank 1 to facilitate observation of the degree of powder mixing.

[0018] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
