[0001] The utility model relates to the technical field of traditional Chinese medicine preparation processing equipment, in particular to a screening device for traditional Chinese medicine preparations. Background Art
[0002] Traditional Chinese medicine preparations must be made into a form suitable for medical or preventive applications before any drug is used clinically, which is called a dosage form. Traditional Chinese medicine preparations mainly include dosage forms such as tablets, injections, aerosols, pills, powders, and ointments. The processing and production of traditional Chinese medicine preparations mainly include processes such as cutting, cleaning, pulverizing, extracting, separating and refining, concentrating, and sterilizing. Moreover, the quality differences of traditional Chinese medicine raw materials with large size differences are also relatively large. Therefore, it is necessary to screen the traditional Chinese medicine raw materials through a screening device to ensure the quality of the finished traditional Chinese medicine preparations.
[0003] At present, most screening devices filter the medium through a sieve mesh, and classify the solid components in the mixture according to the particle size to meet the requirements of different traditional Chinese medicine preparations for the fineness of raw materials. However, during use, the sieve mesh is easily blocked, and it needs to be frequently cleaned, resulting in low screening efficiency, increased maintenance costs, and downtime.
[0004] In summary, there is an urgent need for a screening device for traditional Chinese medicine preparations with higher screening efficiency to solve the above problems. Content of the Utility Model
[0005] In order to overcome the shortcomings that the sieve mesh of the current screening device is easily blocked, needs to be frequently cleaned, and has low screening efficiency, the utility model needs to provide a screening device for traditional Chinese medicine preparations with higher screening efficiency.

[0008] Optionally, the contact block is horizontally arranged on the outer ring of the screening frame, the wedge plate is longitudinally arranged on the upper side of the guide frame, and the width of the contact block is greater than the width of the wedge plate.
[0009] Optionally, the guide frame is arranged at an angle of 45° between the upper sides of the support frame and the connecting plate, and the height of the left side of the guide frame is higher than that of the right side.
[0010] Optionally, the screening frame is composed of an outer frame, a screening mesh and an inner frame. The screening mesh is connected between the outer frame and the inner frame, and the two first guide rods are located inside the inner frame of the screening frame.
[0011] Optionally, the scraper is arranged in a Z shape on the contact plate, and the rear side of the scraper is located between the outer frame and the inner frame of the screening frame.
[0012] Advantages of the present utility model:

Detailed implementation mode
[0019] The following is only a preferred embodiment of the present utility model, and does not limit the protection scope of the present utility model accordingly.
[0020] Embodiment: A screening device for traditional Chinese medicine preparations, as Figures 1 - 4 shown, includes a support frame 1, a motor 2, a first guide rod 3, a screening frame 4, a spring 5, a guide frame 6, a connecting plate 7, a guide rail 11, a contact block 12 and a wedge plate 13. The support frame 1 is the installation carrier of the parts. The motor 2 is installed on the upper side of the support frame 1. The connecting plate 7 is installed on the upper side of the support frame 1. The connecting plate 7 is located on the right side of the motor 2. The guide frame 6 is arranged at 45° between the upper sides of the support frame 1 and the connecting plate 7. The height of the left side of the guide frame 6 is higher than that of the right side. A collection port is opened on the right side of the guide frame 6. A connecting shaft 14 is rotatably connected to the guide frame 6. The first guide rods 3 are symmetrically and fixedly connected to the connecting shaft 14 on the left and right. The screening frame 4 is slidably connected between the two first guide rods 3. The screening frame 4 is composed of an outer frame, a screening mesh, an inner frame and a bottom plate. The screening mesh is connected between the outer frame and the inner frame. The bottom plate is connected to the inner frame to form the bottom surface of the inner frame. The two first guide rods 3 are slidably connected to the bottom plate of the screening frame 4. A spring 5 is wound between the first guide rod 3 and the screening frame 4. Three contact blocks 12 are fixedly connected to the outer circle of the screening frame 4. Three wedge plates 13 are fixedly connected to the guide frame 6. The contact block 12 and the wedge plate 13 are at the same height. The width of the contact block 12 is greater than the width of the wedge plate 13. By starting the motor 2 to drive the screening frame 4 to rotate, the contact block 12 and the wedge plate 13 are in contact and cooperate to realize the repeated vibration of the screening frame 4 to screen the traditional Chinese medicine preparations.
[0021] As Figure 3 shown, it further includes a second guide rod 8, a scraper 9, a contact plate 10 and a guide rail 11. The second guide rod 8 is fixedly connected to the outer circle of the guide frame 6. The guide rail 11 is connected to the outer circle of the screening frame 4. The guide rail 11 is located below the contact block 12; The contact plate 10 is slidably connected to the second guide rod 8. The rear side of the contact plate 10 is slidably connected to the guide rail 11; The scraper 9 is arranged in a Z shape on the contact plate 10. The rear side of the scraper 9 is located between the outer frame and the inner frame of the screening frame 4. The scraper 9 scrapes off the traditional Chinese medicine preparations remaining on the outer frame and the inner frame of the screening frame 4 and falls onto the guide frame 6 and then into the collection bag through the collection port on the guide frame 6.
[0022] When the device needs to be used, start the motor 2. The output shaft of the motor 2 rotates to drive the connecting shaft 14 to rotate. The connecting shaft 14 drives the screening frame 4, the contact block 12 and the guide rail 11 to rotate through the first guide rod 3. When the contact block 12 rotates, it contacts the side surface of the wedge-shaped plate 13 and moves upward under its influence. The spring 5 deforms adaptively. The contact block 12 drives the corresponding components to move. When the contact block 12 is displaced to the other side of the upper side surface of the wedge-shaped plate 13, the contact block 12 moves downward under the action of gravity and disengages from the wedge-shaped plate 13. The spring 5 returns to its original state. The screening frame 4, the guide rail 11, the scraper 9 and the contact plate 10 are reset under the elastic force of the spring 5. Repeating this process enables the screening frame 4 to vibrate repeatedly. Pour the traditional Chinese medicine preparation into the screening frame 4. The screening frame 4 screens the traditional Chinese medicine preparation during repeated vibrations. The traditional Chinese medicine preparation remaining outside and inside the outer frame of the screening frame 4 is scraped off by the scraper 9 and then falls into the screening frame 4 for screening again. The screening efficiency is relatively high. The traditional Chinese medicine preparation that has completed screening falls into the guiding frame 6 and is collected into the collection bag through the collection port on the guiding frame 6. After the screening operation is completed, the staff can turn off the motor 2.
[0023] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
