Description

Technical Field

[0001] This utility model relates to the field of drug sieving technology, specifically a drug oscillating sieving device. Background Technology

[0002] Drugs are substances used to prevent, treat, and diagnose diseases. Theoretically, drugs refer to any chemical substance that can affect the physiological functions of organs and cellular metabolic activities. Drug sieving is a very important step in the pharmaceutical process and is usually used for the processing and preparation of drug raw materials.

[0003] The drug may contain non-compliant impurities or large particles, which may affect the quality of the drug and thus require separation. However, although the existing vibrating sieving device can separate granular and powdered drugs, due to the vibration effect, some powder will be mixed with the air and inhaled by nearby workers, which may cause harm to their health. Furthermore, without baffles, granular drugs may be shaken out of the device due to continuous vibration, resulting in losses.

[0004] Therefore, those skilled in the art have provided a drug shaking and sieving device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a drug oscillation and sieving device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drug oscillating sieving device includes a sieving machine body, a dust collection mechanism, and a leak-proof mechanism. The bottom of the sieving machine body is provided with a base, and multiple sets of damping springs are fixedly connected between the base and the sieving machine body. The dust collection mechanism is provided inside the base. The upper end of the sieving machine body is equipped with an upper mold seat, and the upper end of the upper mold seat is provided with a leak-proof mechanism.

[0008] As a further embodiment of this utility model: an annular baffle is slidably connected inside the upper mold base, and multiple sets of air suction holes are opened on the inner side wall of the annular baffle.

[0009] As a further embodiment of this utility model: both the annular baffle and the outer wall of the upper mold base are provided with snap-fit ​​grooves, and a snap-fit ​​rod is movably snapped in the snap-fit ​​grooves of the annular baffle and the upper mold base. A return spring is sleeved and connected to the outer wall of the snap-fit ​​rod. One end of the return spring is fixedly connected to the upper mold base, and the other end of the return spring is fixedly connected to the snap-fit ​​rod.

[0010] As a further embodiment of this utility model: a partition plate is fixedly connected inside the base, and a vacuum cleaner body is provided at the bottom of the partition plate. The vacuum cleaner body is fixedly connected to the inner wall of the base. Two sets of vacuum pipes are connected through and fixedly connected between the base and the annular baffle. Both vacuum pipes are corrugated pipes.

[0011] As a further improvement of this utility model: a vibration motor is fixedly connected to the upper end of the partition plate, and the power output end of the vibration motor is fixedly connected to the screening machine body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Because it is equipped with a dust collection mechanism, the suction function of the dust collector can effectively remove drug powder impurities generated during the sieving process, prevent these dusts from entering the air, reduce air pollution and potential health hazards to operators, and help to centrally process dust impurities by concentrating the collected impurities at the bottom of the partition plate in the base.

[0014] 2. Equipped with a leak-proof mechanism, the granular drugs can be effectively restricted from moving during the sieving process through the locking rod and the annular baffle, preventing them from falling due to vibration or bumps. This ensures a more stable sieving process and effectively avoids drug waste. In particular, during the drug sieving process, it can better retain the sieved drug components, reducing losses. Furthermore, when not in use, the position of the annular baffle can be adjusted and locked independently. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Reference Figure 1-4 This embodiment provides a drug oscillating sieving device, including a sieving machine body 1, a base 2, an upper mold base 3, an annular baffle 4, an air suction hole 5, a snap-fit ​​groove 6, a snap-fit ​​rod 7, a reset spring 8, a partition plate 9, a vibration motor 10, a vacuum cleaner body 11, a vacuum pipe 12, and a damping spring 13. The bottom end of the sieving machine body 1 is provided with a base 2, and multiple sets of damping springs 13 are fixedly connected between the base 2 and the sieving machine body 1. A vacuuming mechanism is provided inside the base 2. The upper end of the sieving machine body 1 is equipped with an upper mold base 3, and a leak-proof mechanism is provided at the upper end of the upper mold base 3. The upper end of the partition plate 9 is fixedly connected to the vibration motor 10, and the power output end of the vibration motor 10 is fixedly connected to the sieving machine body 1.

[0023] Example 2

[0024] Reference Figure 1 , 2 3. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that an annular baffle 4 is slidably connected inside the upper mold base 3. Multiple sets of air suction holes 5 are opened on the inner side wall of the annular baffle 4. Both the annular baffle 4 and the outer side wall of the upper mold base 3 are provided with snap-fit ​​grooves 6. A snap-fit ​​rod 7 is movably snapped in the snap-fit ​​grooves 6 of the annular baffle 4 and the upper mold base 3. A return spring 8 is sleeved and connected to the outer side wall of the snap-fit ​​rod 7. One end of the return spring 8 is fixedly connected to the upper mold base 3, and the other end of the return spring 8 is fixedly connected to the snap-fit ​​rod 7.

[0025] The drugs are placed uniformly on the upper part of the screening machine body 1, and the vibration motor 10 is started to screen the drugs. The multiple sets of damping springs 13 between the base 2 and the screening machine body 1 will provide auxiliary work.

[0026] Before screening, pull out the locking rod 7 to disengage it from the locking groove 6 where the annular baffle 4 and the upper mold base 3 overlap, causing the annular baffle 4 to disengage from its limit position. After pulling the annular baffle 4 out to a certain height, release the locking rod 7 to reset the return spring 8, which then re-engages it into the locking groove 6 where the annular baffle 4 and the upper mold base 3 overlap, locking the position of the annular baffle 4. This prevents granular drugs from being subjected to excessive vibration and falling out of the screening machine body 1 during drug screening.

[0027] Example 3

[0028] Reference Figure 1 , 2 4. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that a partition plate 9 is fixedly connected inside the base 2, a vacuum cleaner body 11 is provided at the bottom of the partition plate 9, the vacuum cleaner body 11 is fixedly connected to the inner wall of the base 2, and two sets of vacuum pipes 12 are connected through and fixedly connected between the base 2 and the annular baffle 4. Both vacuum pipes 12 are corrugated pipes.

[0029] Some drug powder may be mixed in the air due to the external force of the vibration of the sieving machine body 1. The vacuum cleaner body 11 can be activated. The vacuum cleaner body 11 continuously sucks air through the suction pipe 12 and the suction hole 5 opened in the inner wall of the annular baffle 4, and sucks such impurities to the bottom of the partition plate 9 in the base 2 for unified treatment.
