Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical mixing technology, specifically a pharmaceutical mixing device. Background Technology
[0002] Drug mixing usually refers to the process of mixing different raw materials or excipients in a certain proportion during the formulation process to ensure that the quality of each tablet or each batch is consistent. It usually involves mixing two or more drugs or ingredients in a specific proportion to achieve the expected therapeutic effect or to prepare a specific drug.
[0003] The prior art, CN219050964U, discloses a drug mixing device, including a support frame with a mixing tank disposed between the support frame and connecting shafts fixedly connected to both ends of the mixing tank. Both connecting shafts are fixedly connected to the support frame, and a servo motor is fixedly connected to one side of the support frame. The drive end of the servo motor passes through the support frame and the connecting shafts and extends into the interior of the mixing tank. In use, the cleaning mechanism activates the servo motor, causing it to reverse and rotate the one-way bearing. This causes the vertical and horizontal rods to rotate inside the mixing tank. Brushes on the surfaces of the vertical and horizontal rods clean the inner wall of the mixing tank, facilitating cleaning and avoiding the need for time-consuming post-mixing cleaning, thus improving both the time required for cleaning the mixing tank and the efficiency of mixing Western medicine.
[0004] With the above configuration, the existing mixing device uses a cleaning mechanism to activate a servo motor, causing the servo motor to reverse and drive a one-way bearing to rotate. This causes the vertical and horizontal rods to rotate inside the mixing tank. Brushes on the surfaces of the vertical and horizontal rods clean the inner wall of the mixing tank, facilitating cleaning and avoiding the need for time-consuming post-mixing cleaning, thus improving both the time required for cleaning the mixing tank and the efficiency of mixing the medicine. However, the existing mixing device has the following drawbacks during operation:
[0005] The existing mixing device cleans the inner wall of the mixing tank by brushes on vertical and horizontal bars. However, after prolonged use, the surface of the brushes will wear down. Since the vertical bar and the one-way bearing are welded together, the brushes cannot be disassembled and replaced. As a result, the worn brushes cannot clean the inner wall of the mixing tank, reducing the cleaning effect. Utility Model Content
[0006] The present invention aims to provide a medicine mixing device, which is mainly used to solve the technical problem that the brushes in the prior art wear out after long-term use and cannot be replaced, which affects the cleaning of the inner wall of the mixing tank and reduces the cleaning effect.
[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0008] A pharmaceutical mixing device includes a mixing tank, a drive motor, and a one-way bearing. The drive motor is fixed to one side of the mixing tank. The output end of the drive motor passes through the mixing tank and is fixed to the inner wall of the one-way bearing. A retaining ring is fixed to the outer wall of the one-way bearing. A slot is formed on the outer wall of the retaining ring. A cleaning component is installed on the inner wall of the slot. A through groove is formed on the outer wall of the mixing tank. A protective plate is snapped into the inner wall of the through groove. A fixing plate is fixed to the outer wall of the protective plate. The fixing plate abuts against the outer wall of the mixing tank. A fixing component for fixing the fixing plate is installed at one end of the mixing tank.
[0009] The working principle and beneficial effects of this utility model:
[0010] 1. Working principle: When it is necessary to clean the inside of the mixing tank, the drive motor is started to drive the cleaning brush for cleaning. When the cleaning brush is worn, the fixing component is adjusted and the fixing plate is pulled to move the protective plate, so that the through slot is opened. Then the sliding plate is pulled, so that the sliding plate moves the limiting plate, so that the limiting plate squeezes the limiting spring and retracts into the movable slot. Then the cleaning brush is pulled upward to make the insert block disengage from the slot, and then the cleaning brush can be replaced.
[0011] 2. Beneficial effects:
[0012] Existing technology uses a cleaning mechanism to activate a servo motor, which reverses to drive a one-way bearing, causing the vertical and horizontal rods to rotate inside the mixing tank. Brushes on the surfaces of the vertical and horizontal rods clean the inner wall of the mixing tank, facilitating cleaning and avoiding the need for time-consuming post-mixing cleaning, thus improving both cleaning time and the efficiency of mixing medicines. However, while existing mixing devices use brushes on the vertical and horizontal rods for cleaning, these brushes tend to develop surface defects after prolonged use. Wear and tear are a problem. Because the vertical rod and the one-way bearing are welded together, the brush cannot be disassembled and replaced. As a result, the worn brush cannot clean the inner wall of the mixing tank, reducing the cleaning effect. This solution uses a fixing ring, a protective plate, a fixing plate, an insert block, and a fixing assembly. By adjusting the fixing assembly, the vertical rod is disengaged from the through hole, and the fixing plate is pulled to move the protective plate, causing the first fixing block to disengage from the fixing groove, opening the through groove. Then, the sliding plate is pulled to disengage the limiting plate from the limiting groove, allowing the insert block to be pulled out of the slot and disengage from the fixing ring. This allows the cleaning brush to be replaced, avoiding the technical problem of the cleaning brush being unable to be replaced after wear.
[0013] Preferably, the cleaning assembly includes an insert block that plugs into a slot. A cleaning brush is fixedly attached to the outer wall of the insert block, and the cleaning brush contacts the inner wall of the mixing tank. Symmetrical movable grooves are formed at both ends of the insert block. A limiting plate is slidably connected to the inner wall of each movable groove, and symmetrical limiting springs are fixedly attached to the inner wall of each movable groove. The other end of each limiting spring is fixedly connected to a limiting plate. Symmetrical limiting grooves are formed at both ends of the slot, and the limiting plate plugs into these grooves. A sliding groove is formed on the outer wall of the insert block, and a sliding plate is slidably connected to the inner wall of the sliding groove. The sliding plate is fixedly connected to the outer wall of the limiting plate. By configuring the cleaning assembly, the cleaning brush on the assembly can clean the inner wall of the mixing tank. Simultaneously, by pulling the sliding plate, the limiting plate can be disengaged from the limiting groove, allowing the cleaning brush to be disassembled and replaced.
[0014] Preferably, the fixing assembly includes a first fixing block, which is fixedly connected to one end of a fixing plate. A second fixing block is fixedly connected to one end of the mixing tank. A fixing groove is formed on one side of the second fixing block, and the first fixing block is inserted into the fixing groove. A vertical groove is formed on the upper surface of the first fixing block, and a vertical rod is slidably connected to the inner wall of the vertical groove. A fixing spring is fixedly connected to the inner wall of the vertical groove, and the other end of the fixing spring is fixedly connected to the vertical rod. A through hole is formed on the inner wall of the fixing groove, and a sliding plate is slidably connected to the inner wall of the through hole. A push rod is fixedly connected to one side of the sliding plate, and the vertical rod is inserted into the through hole and abuts against the sliding plate. By setting up the fixing assembly, the protective plate can be opened, and then the parts inside the mixing tank can be repaired, and the cleaning brush can be removed and replaced from the inside of the mixing tank.
[0015] Preferably, symmetrical support legs are fixedly connected to both ends of the mixing tank. The support legs are triangularly arranged, and a support plate is fixedly attached to the bottom surface of the support legs. By setting up support legs, the supporting force of the mixing tank can be improved, preventing the mixing tank from tipping over.
[0016] Preferably, a sealing gasket is fixed to the side of the protective plate that contacts the through-slot. The sealing gasket prevents the medicine from flowing out of the through-slot.
[0017] Preferably, a push plate is fixedly connected to the end of the push rod away from the slide plate, and an anti-slip pad is fixedly connected to the outer wall of the push plate. This increases the friction between the fingers and the push plate. Attached Figure Description
