Description

Technical Field

[0001] This utility model relates to a transmission device for a medical material intermediate production line, belonging to the field of pharmaceutical production equipment. Background Technology

[0002] The conveying device in the medical material intermediate production line plays a key role in the entire pharmaceutical production process. It is mainly used for the handling, conveying and distributing of drug raw materials. Powdered medical material intermediates are conveyed by pipelines and airflow.

[0003] In existing technologies, during drug production, powdered medical material intermediates need to be transported to a reaction vessel and diluted and mixed with liquid. However, the pipeline for transporting the powdered medical material intermediates is always connected to the vessel body, which makes it easy for humid gases generated during the mixing and dilution process to flow back into the pipeline, resulting in dampness on the inner wall of the pipeline. This makes it easy for a large amount of drug powder to adhere to the inner wall of the pipeline during the secondary transport of powder, thus requiring an increase in the cleaning frequency of the pipeline. The dampness of the pipeline also makes it easy for mold to grow, reducing the quality of the production and transport environment for medical material intermediates.

[0004] In summary, this utility model provides a transmission device for a medical material intermediate production line to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a transmission device for a medical material intermediate production line, so as to solve the problem mentioned in the background art that the conveying pipeline cannot avoid the backflow of humid gas, resulting in the inner wall of the pipeline being damp and the drug powder sticking to it.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a transmission device for a medical material intermediate production line, comprising a conveying pipe and a feeding pipe, wherein the feeding pipe is obliquely and fixedly installed on one side of the conveying pipe, a fixed cylinder is installed at the top end of the conveying pipe, a push block is sleeved on the inner tube of the conveying pipe, an electric telescopic component passes through the top of the fixed cylinder, the bottom end of the electric telescopic component passes through the top end of the conveying pipe and extends to the top of the push block, and a sealing sleeve is sleeved on the outside of the push block.

[0007] Furthermore, the feed pipe is connected to the conveying pipe, the bottom end of the fixed cylinder is open, and the top end of the conveying pipe is closed.

[0008] Furthermore, the electric telescopic assembly includes a housing, which is fixedly connected to the top of the fixed cylinder. A micro motor is fixedly connected inside the housing, and a threaded rod is fixedly connected to the output end of the micro motor. One end of the threaded rod passes through the housing and the fixed cylinder in sequence and extends into the interior of the fixed cylinder. A threaded sleeve is fitted outside the threaded rod and inside the fixed cylinder. The bottom end of the threaded sleeve passes through the conveying pipe and the sealing sleeve in sequence and extends to the top of the push block.

[0009] Furthermore, the threaded rod is rotatably connected to the housing, and the threaded rod is rotatably connected to the fixed cylinder.

[0010] Furthermore, the threaded rod is threadedly connected to the threaded sleeve, and the outer edge of the top end of the threaded sleeve is in the shape of a convex ring.

[0011] Furthermore, a through hole is provided between the top of the fixed cylinder and the top of the inner wall, through which a threaded sleeve passes, and a sealing ring is fixedly fitted on the inner wall of the through hole.

[0012] Furthermore, the bottom end of the threaded sleeve is fixedly connected to the push block, and the top of the sealing sleeve is provided with a through hole through which the threaded sleeve passes.

[0013] The beneficial effects of this utility model are:

[0014] By activating the switch at the output end of the micro motor inside the electric telescopic assembly and rotating it clockwise, the threaded rod rotates clockwise. The threaded rod drives the threaded sleeve to move downward, and the threaded sleeve pushes the push block downward. The push block seals the bottom end of the delivery pipe through the sealing sleeve, blocking the connection between the bottom end of the feed pipe and the delivery pipe. This prevents humid gas from flowing back into the inside of the feed pipe during the drug mixing process, avoids the phenomenon of powdered medical material intermediates adhering to the inner wall of the feed pipe, reduces the frequency of cleaning the transmission pipeline, and effectively improves the quality of the production and transportation environment for medical material intermediates.

[0015] As the pusher slides downward inside the delivery pipe through the sealing sleeve, it pushes the powder adhering to the inner wall of the delivery pipe downward, effectively reducing drug residue on the inner wall of the delivery pipe and avoiding waste of raw materials during the pharmaceutical production and transportation process.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a transmission device for a medical material intermediate production line, including a conveying pipe 1 and a feeding pipe 2. The feeding pipe 2 is obliquely and fixedly installed on one side of the conveying pipe 1. A fixed cylinder 3 is installed at the top of the conveying pipe 1. A push block 4 is sleeved on the inner tube of the conveying pipe 1. An electric telescopic component 6 passes through the top of the fixed cylinder 3. The bottom end of the electric telescopic component 6 passes through the top of the conveying pipe 1 and extends to the top of the push block 4. A sealing sleeve 5 is sleeved on the outside of the push block 4. The feeding pipe 2 is connected to the conveying pipe 1, and the bottom end of the fixed cylinder 3 is open. The top of the conveying pipe 1 is closed. The outer surface of the pusher 4 is tightly attached to the inner wall of the conveying pipe 1 through the sealing sleeve 5. This allows the pusher 4 to scrape and push the damp medicine adhering to the inner wall of the conveying pipe 1 downwards as it moves from top to bottom. It can also block the connection between the feed pipe 2 and the bottom of the conveying pipe 1, preventing the humid air in the medical material intermediate production process from flowing back into the feed pipe 2 and avoiding the phenomenon of damp drug powder adhering to the wall of the feed pipe 2. The bottom of the conveying pipe 1 can be directly connected to the external medical material intermediate production vessel.

[0024] Please see Figure 2-4The electric telescopic assembly 6 includes a housing 61, which is fixedly connected to the top of the fixed cylinder 3. A micro motor 62 is fixedly connected inside the housing 61. The micro motor 62 is connected to an external power source and is equipped with a power control switch. The micro motor 62 is a three-phase asynchronous motor, and its output end can be adjusted for forward and reverse rotation. A threaded rod 63 is fixedly connected to the output end of the micro motor 62. One end of the threaded rod 63 passes through the housing 61 and the fixed cylinder 3 sequentially and extends into the interior of the fixed cylinder 3. A threaded sleeve 64 is fitted outside the threaded rod 63 and inside the fixed cylinder 3. The bottom end of the threaded sleeve 64 passes through the conveying pipe 1 and the sealing sleeve 5 sequentially and extends to the top of the push block 4. The top cross-section of the threaded sleeve 64 is rectangular, which serves to limit the movement of the threaded sleeve 64. When the threaded rod 63 rotates in both directions, it can drive the threaded sleeve 64 to move up and down. The threaded rod 63 is rotatably connected to the housing 61 and the fixed cylinder 3. The threaded rod 63 is threadedly connected to the threaded sleeve 64. The outer edge of the top of the threaded sleeve 64 is in the shape of a convex ring. The convex ring can limit the downward movement distance of the threaded sleeve 64 to prevent the threaded sleeve 64 from disengaging from the conveying pipe 1. A through hole is opened between the top of the fixed cylinder 3 and the top of the inner wall to accommodate the threaded sleeve 64. A sealing ring 7 is fixedly fitted on the inner wall of the through hole. The sealing ring 7 can improve the sealing performance of the threaded sleeve 64 when it moves up and down at the top of the conveying pipe 1. The bottom of the threaded sleeve 64 is fixedly connected to the push block 4. A through hole is opened at the top of the sealing sleeve 5 to accommodate the threaded sleeve 64.

[0025] Specific implementation method: The powdered medical material intermediate is transported to the top of the feed pipe 2, the feed pipe 2 is used to transport the medical intermediate to the inside of the conveying pipe 1, and the bottom end of the conveying pipe 1 is used to transport the medical intermediate to the external production equipment.

[0026] Before adding liquid for dilution and mixing, turn the switch clockwise at the output end of the micro motor 62 inside the electric telescopic component 6. This will drive the threaded rod 63 to rotate clockwise. The top section of the threaded sleeve 64 is rectangular, which has a limiting effect on the threaded sleeve 64. As the threaded rod 63 rotates clockwise, it drives the threaded sleeve 64 to move downward. The threaded sleeve 64 pushes the push block 4 downward. The push block 4 slides downward inside the delivery pipe 1 through the sealing sleeve 5, pushing the powder adhering to the inner wall of the delivery pipe 1 downward, effectively reducing the drug residue on the inner wall of the delivery pipe 1.

[0027] Meanwhile, the pusher block 4 seals the bottom end of the conveying pipe 1 with the sealing sleeve 5, blocking the connection between the feed pipe 2 and the bottom end of the conveying pipe 1. This prevents humid gas from flowing back into the inside of the feed pipe 2 during the drug mixing process, avoids the phenomenon of powdered medical material intermediates sticking to the inner wall of the feed pipe 2, reduces the frequency of cleaning the transmission pipeline, and effectively improves the quality of the production and conveying environment of medical material intermediates.

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.
