Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical powder screening technology, and in particular to a screening mechanism for the production of soluble powder drugs. Background Technology

[0002] Currently, soluble powder drugs refer to drug powders that can rapidly dissolve in water or other specific solvents to form a homogeneous solution. Drugs of different particle sizes may vary in terms of dissolution rate and bioavailability. Through screening, the particle size distribution of drug powders can be made within a relatively narrow range, ensuring consistent drug release and absorption in the body, thereby guaranteeing the stability and reliability of drug efficacy.

[0003] A pharmaceutical powder sieving device is disclosed in Chinese utility model patent CN220611298U. Although the above-mentioned prior art improves the practicality and efficiency of the pharmaceutical powder sieving device, it only requires shaking the sieving device and the internal screen to sieving. During the sieving process, due to the friction and shaking of the screen, some drug powder will adhere to the screen and the inner wall of the equipment, making it difficult to recover. This is because simple shaking is not enough to make the drug powder adhering to the screen and the inner wall of the equipment fall down for further sieving. This not only wastes drug powder but also reduces the sieving efficiency of the screen. Therefore, it is necessary to design a sieving mechanism that can follow the shaking of the sieving device to knock and vibrate the sieving device, thus preventing drug powder from adhering to the inner wall of the equipment. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a screening mechanism for the production of soluble powder drugs.

[0005] This utility model is achieved using the following technical solution: a sieving mechanism for the production of soluble powder drugs, including a vibrating screen, the vibrating screen is provided with a protective component on its exterior, a plurality of striking components arranged in a ring array on the cylindrical surface of the vibrating screen, and a driving component on one side of each striking component that can cooperate with the vibrating screen to drive the striking component to strike, the protective component including a base at the bottom of the vibrating screen and a protective sleeve on one side of the base, the vibrating screen being located inside the protective sleeve, and a fixing groove adapted to the protective sleeve being opened on the top of the base.

[0006] With the above technical solution, when the vibrating screen screens the medicine powder, the drive component will shake along with the vibrating screen. The shaking of the drive component will cause the striking component to continuously strike the vibrating screen. The vibration will cause the medicine powder adsorbed on the inner wall of the vibrating screen and the screen to fall off. The medicine powder falls on the screen, which makes it convenient for the screen to continue screening. The protection component can both support the striking component and protect the vibrating screen.

[0007] As a further improvement of the above solution, a plurality of first through holes arranged in an annular array are provided on the cylindrical surface of the protective cover. A second through hole penetrating the protective cover is provided directly below each of the first through holes. The knocking component includes a knocking rod arranged inside the first through hole, a sliding sleeve sleeved on the knocking rod in a sliding manner, and a knocking ball fixedly installed at one end of the sliding sleeve.

[0008] Through the above technical solution, when the knocking rod moves further through the first through hole, the sliding sleeve will push the knocking ball to knock on the vibrating screen.

[0009] As a further improvement of the above solution, a pushing spring is provided inside each of the sliding sleeves. Two ends of each pushing spring are fixedly connected to the adjacent knocking ball and the knocking rod respectively.

[0010] Through the above technical solution, the pushing spring will always push the knocking ball, enabling the sliding sleeve to expand and contract, and preventing the knocking ball from pressing against the vibrating screen.

[0011] As a further improvement of the above solution, a plurality of mounting blocks arranged in an annular array are fixedly installed on the cylindrical surface of the protective cover. A rotating ball is rotatably installed on one side of each mounting block. A pushing plate is fixedly installed on one side of each rotating ball. Two first fixing plates are fixedly installed on one side of the top end of each pushing plate. One end of each knocking rod extends between two adjacent first fixing plates and is rotatably engaged with them.

[0012] Through the above technical solution, when the pushing plate shakes on the mounting block, the first fixing plate will push the knocking rod, so that the sliding sleeve can drive the knocking ball to knock on the vibrating screen.

[0013] As a further improvement of the above solution, the driving component includes two second fixing plates fixedly installed on one side of the bottom end of the pushing plate, and a pushing rod arranged between the two second fixing plates and rotatably engaged with the two second fixing plates. One end of each pushing rod passes through the adjacent second through hole and extends into the interior of the protective cover. A limiting plate is rotatably installed at one end of each pushing rod. The limiting plate is arranged in a "C" shape.

[0014] Through the above technical solution, after the limiting plate is driven by the vibrating screen, it will带动 the pushing rod to move together, so that the second fixing plate can drive the pushing plate to shake.

[0015] As a further improvement of the above solution, a magnet is adsorbed on one side of each limiting plate, and each magnet is fixedly connected to the vibrating screen. [[ID=?]]

[0016] Using the above technical solution, the magnet will hold the limiting plate in place, so that when the vibrating screen shakes, the limiting plate will shake along with it.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention incorporates a protective component, a striking component, and a driving component. When the vibrating screen is screening medicinal powder, the driving component shakes along with the vibrating screen. This shaking causes the striking component to continuously strike the vibrating screen. The vibration causes the medicinal powder adsorbed on the inner wall of the vibrating screen and on the screen to fall off. The powder falling onto the screen facilitates further screening. The protective component provides support for the striking component and also protects the vibrating screen. Attached Figure Description

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0026] Please combine Figures 1-4This embodiment provides a sieving mechanism for the production of soluble powder drugs, including a vibrating screen 1. The vibrating screen 1 is provided with a protective component on its exterior. The cylindrical surface of the vibrating screen 1 is provided with a plurality of striking components arranged in a ring array. Each striking component has a driving component on one side that can cooperate with the vibrating screen 1 to drive the striking component to strike. The protective component includes a base 201 provided at the bottom of the vibrating screen 1 and a protective sleeve 202 provided on one side of the base 201. The vibrating screen 1 is located inside the protective sleeve 202. The top of the base 201 is provided with a fixing groove that is adapted to the protective sleeve 202.

[0027] When the vibrating screen 1 is screening the medicine powder, the drive component will shake along with the vibrating screen 1. The shaking of the drive component will cause the striking component to continuously strike the vibrating screen 1. The vibration will cause the medicine powder adsorbed on the inner wall of the vibrating screen 1 and the screen to fall off. The medicine powder falls on the screen, which makes it convenient for the screen to continue screening. The protection component can both support the striking component and protect the vibrating screen 1.

[0028] The cylindrical surface of the protective sleeve 202 has multiple first through-holes 5 arranged in a ring array. Directly below each first through-hole 5, there is a second through-hole 6 that penetrates the protective sleeve 202. The striking assembly includes a striking rod 301 disposed inside the first through-hole 5, a sliding sleeve 302 slidably sleeved on the striking rod 301, and a striking ball 303 fixedly installed at one end of the sliding sleeve 302. Each sliding sleeve 302 is provided with a push spring 7 inside. The two ends of each push spring 7 are fixedly connected to the adjacent striking ball 303 and striking rod 301, respectively.

[0029] As the striking rod 301 continues to move through the first through-hole 5, the sliding sleeve 302 will push the striking ball 303 to strike the vibrating screen 1. The pushing spring 7 will continuously push the striking ball 303, allowing the sliding sleeve 302 to extend and retract, thus preventing the striking ball 303 from blocking the vibrating screen 1.

[0030] Multiple mounting blocks 8 arranged in a circular array are fixedly installed on the cylindrical surface of the protective sleeve 202. A rotating ball is rotatably installed on one side of each mounting block 8. A push plate 9 is fixedly installed on one side of each rotating ball. Two first fixing plates 10 are fixedly installed on one side of the top of each push plate 9. One end of each striking rod 301 extends between two adjacent first fixing plates 10 and rotates with them.

[0031] When the push plate 9 shakes on the mounting block 8 and the rotating ball, it causes the first fixed plate 10 to push the striking rod 301, thereby allowing the sliding sleeve 302 to drive the striking ball 303 to strike the vibrating screen 1.

[0032] The driving component includes two second fixing plates 401 fixedly installed on one side of the bottom end of the pushing plate 9, and a pushing rod 402 disposed between the two second fixing plates 401 and rotatably engaged with the two second fixing plates 401. One end of each pushing rod 402 passes through the adjacent second through hole 6 and extends into the interior of the protective sleeve 202. A limiting plate 403 is rotatably installed at one end of each pushing rod 402. The limiting plate 403 is arranged in a "C" shape. A magnet 11 is adsorbed on one side of each limiting plate 403. Each magnet 11 is fixedly connected to the vibrating screen 1.

[0033] After the limiting plate 403 is driven by the vibrating screen 1, it will带动 the pushing rod 402 to move together, so that the second fixing plate 401 drives the pushing plate 9 to shake.

[0034] In the embodiment of the present application, the implementation principle of a screening mechanism for soluble powder drug production is as follows: Place the vibrating screen 1 on the base 201, then cover the protective sleeve 202, and adsorb multiple limiting plates 403 on the magnets 11.

[0035] When starting the vibrating screen 1 to screen the medicinal powder, the vibrating screen 1 will shake in multiple directions. When shaking, the magnet 11 will also move accordingly, so that the limiting plate 403 moves. The movement of the limiting plate 403 will pull the pushing rod 402 to move. The movement of the pushing rod 402 will pull the pushing plate 9 to move. In this way, the pushing plate 9 will rotate at multiple angles around the position where the rotating ball is located, so that the pushing plate 9 can pull the knocking rod 301 to move. The movement of the knocking rod 301 will cause the pushing spring 7 inside the sliding sleeve 302 to move, so as to pull the sliding sleeve 302 and the knocking ball 303 to move together. Such movement will move in the opposite direction to the pushing rod 402. The pushing rod 402 extends out of the protective sleeve 2, and the knocking rod 301 will extend into the protective sleeve 202, so that the knocking ball 303 can knock the vibrating screen 1. And when the vibrating screen 1 shakes, due to the multiple pushing rods 402 generating different directions of movement, the rotating ball, the fitting block 8, and the pushing plate 9 can generate multi-angle shaking, avoiding affecting the shaking of the vibrating screen 1.

[0036] When the shaking is too剧烈, the limiting plate 403 will also directly separate from the magnet 11, thus avoiding damage to the parts.

[0037] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
