[0033] Please see Figure 1-6 This utility model provides a technical solution: a drug screening device for drug processing, including a drug screening box 1 and a drug screening assembly. The drug screening assembly is disposed inside the drug screening box 1 and includes a first fixing frame 7, which is fixedly connected to the inside of the drug screening box 1. A drug screening frame 8 is disposed inside the drug screening box 1. The drug screening frame 8 is disc-shaped with a higher center and lower edges. Four screening frame connecting rods 12 are fixedly connected to the upper end of the first fixing frame 7. Each of the four screening frame connecting rods 12 has a return spring 13 sleeved on its surface. The screening frame connecting rods 12 are all slidably connected to the drug screening frame 8. The two ends of the four return springs 13 are respectively fixedly connected to the drug screening frame 8 and the first fixing frame 7. The upper end of the drug screening box 1 is fixedly connected to the drive motor 9. The output end of the drive motor 9 is fixedly connected to the rotating shaft 10. The rotating shaft 10 is rotatably connected to the drug screening box 1. The lower end of the drug screening frame 8 is fixedly connected to the screening frame connecting block 14. The surface of the rotating shaft 10 is fixedly connected to the fixing block 15. The edges of the screening frame connecting block 14 and the fixing block 15 are both wavy. The screening frame connecting block 14 and the fixing block 15 are rotatably connected.

[0034] The drug screening assembly also includes a drug guide plate 4, which is cleanly disposed inside the drug screening box 1. A drug guide cylinder 5 is fixedly connected inside the drug guide plate 4. A second drug discharge pipe 6 is fixedly connected to the right end of the drug screening box 1. The second drug discharge pipe 6 communicates with the inside of the drug screening box 1. Four discharge ports 11 are fixedly connected to the edge of the drug screening frame 8.

[0035] A drug feed pipe 2 is fixedly connected to the upper end of the drug screening box 1, and the drug feed pipe 2 is located above the drug screening frame 8.

[0036] The drug screening box 1 is internally fixedly connected to a second fixed frame 16, which is in the shape of a cross. The rotating shaft 10 is rotatably connected to the second fixed frame 16. Two receiving trays 17 are fixedly connected to the surface of the rotating shaft 10. The two receiving trays 17 are arranged vertically and are both frustum-shaped.

[0037] The lower end of the drug screening box 1 is fixedly connected to the first drug discharge pipe 3, which is funnel-shaped.

[0038] The first drug discharge pipe 3 has two baffles 18 fixedly connected inside, and both baffles 18 are fan-shaped.

[0039] Four spiral blades 19 are fixedly connected to the surface of the rotating shaft 10.

[0040] When using this device, the drug is first added from the inside of the drug screening box 1 through the drug feed pipe 2 and falls onto the surface of the drug screening frame 8. The drive motor 9 is started to drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the fixed block 15 to rotate. Through the rotational connection between the screening frame connecting block 14 and the fixed block 15, and the fact that the edges of the screening frame connecting block 14 and the fixed block 15 are both wavy, it is easy to squeeze the screening frame connecting block 14 during the rotation of the fixed block 15. This causes the screening frame connecting block 14 to drive the drug screening frame 8 to move up and down during the rotation of the fixed block 15, so that the drug screening frame 8 slides on the surface of the screening frame connecting rod 12. The setting of four return springs 13 makes it easy to stabilize the position of the drug screening frame 8 and to generate vibration during the up and down movement of the drug screening frame 8, so as to facilitate the drug screening by the drug screening frame 8.

[0041] The wavy design of the edges of the screening frame connecting block 14 and the fixing block 15 can effectively disperse stress and avoid excessive stress concentration at the contact point, thereby extending the service life of the screening frame connecting block 14 and the fixing block 15 and facilitating stability during the rotation of the screening frame connecting block 14.

[0042] The design of the drug screening frame 8, which is high in the middle and low at the edges, helps the material to gather in the central area of ​​the drug screening frame 8 and gradually disperse towards the edge as the drug screening frame 8 tilts. The reciprocating up and down movement of the drug screening frame 8 is the key action in the screening process. When the screen moves upward, the material will be lifted and slide down to the lower part (i.e. the edge) of the drug screening frame 8 under the action of gravity. Smaller particles or drugs that meet the screen mesh size will fall through the drug screening frame 8, achieving separation from larger particles.

[0043] When the drug screening box 8 moves downward, the drug is agitated and dispersed again, which helps to further improve the screening effect. This reciprocating up and down movement not only promotes the turning and loosening of the drug, but also ensures the continuity and stability of the screening process.

[0044] When the screening frame connecting block 14 moves the drug screening frame 8 up and down, the return spring 13 will generate a reaction force, so that the drug screening frame 8 can automatically return to the initial position after the external force disappears. This reset action helps to maintain the stability and positional accuracy of the drug screening frame 8, ensuring the continuity and accuracy of the screening process. The return spring 13 can reduce the stress concentration of the drug screening frame 8 under vibration and impact, thereby reducing the fatigue damage and wear rate of the drug screening frame 8, which helps to extend the service life of the drug screening frame 8.

[0045] Because the drug screening frame 8 is shaped with a high center and low edges, it facilitates drug screening. Drugs that meet the requirements fall through the sieve holes of the drug screening frame 8. Drugs larger than the sieve holes fall from the discharge port 11 onto the surface of the drug guide plate 4. The setting of the drug guide cylinder 5 facilitates the blocking of drugs on both sides of the drug guide cylinder 5, preventing drugs on both sides of the drug guide cylinder 5 from mixing together again and affecting the screening of drugs. Since the drug guide plate 4 is fixed in an inclined shape inside the drug screening box 1, it facilitates the flow of drugs and ensures that the drugs can be guided evenly and stably to the second drug discharge pipe 6, so that the drugs on the surface of the drug guide plate 4 can be discharged from the second drug discharge pipe 6.

[0046] As the drug falls through the sieve holes of the drug screening frame 8, it will fall onto the two receiving trays 17 in sequence, which helps to block the drug and prevent it from falling directly into the first drug discharge pipe 3, reducing the kinetic energy of the drug when it falls and preventing the drug from falling too fast.

[0047] The two receiving trays 17 also serve to disperse the drug. If the drug falls directly onto the first drug discharge pipe 3 during its descent, it may cause excessive local drug discharge, affecting the discharge of the drug. By setting two receiving trays 17, the drug can be dispersed during its descent. The rotating shaft 10 drives the receiving trays 17 to rotate, which facilitates the centrifugal action when the drug is on the surface of the receiving trays 17, preventing the drug from accumulating on the surface of the receiving trays 17 and affecting the collection of the drug. This makes it easier to evenly distribute the drug on the inner wall surface of the first drug discharge pipe 3. The rotating shaft 10 drives the spiral blades 19 to rotate, and the baffle plate 18 facilitates the uniformity of the drug during discharge. The first drug discharge pipe 3, the baffle plate 18, and the spiral blades 19 divide the internal space of the first drug discharge pipe 3 into four parts, which facilitates the discharge of the drug from the gaps between the first drug discharge pipe 3 and the baffle plate 18, making it easier to discharge the drug stably and preventing the drug from accumulating inside the first drug discharge pipe 3, which would affect the discharge of the drug and thus affect the drug screening efficiency.

[0048] The second fixing frame 16 is arranged in a cross shape, which facilitates the limiting of the rotating shaft 10, making it easier for the rotating shaft 10 to remain stable during rotation, thereby improving the stability of the rotating shaft 10 and thus improving the stability of the device.

[0049] Furthermore, by moving the drug screening frame 8 up and down, and by making the drug screening frame 8 a disc with a high center and low edges, the drug is facilitated to gradually disperse towards the edges as the drug screening frame 8 tilts. This reciprocating up and down movement not only promotes the turning and loosening of the drug and prevents the drug from clogging the sieve holes, but also ensures the continuity and stability of the screening process.

[0050] The reset spring 13 facilitates the reset of the drug screening frame 8 during its up-and-down movement, helping to maintain the stability and positional accuracy of the drug screening frame 8, ensuring the continuity and accuracy of the screening process. The reset spring 13 can reduce stress concentration of the drug screening frame 8 under vibration and impact, thereby reducing fatigue damage and wear rate of the drug screening frame 8, which helps to extend the service life of the drug screening frame 8.

[0051] The use of receiving trays 17 facilitates the blocking of falling drugs, reducing the kinetic energy of the drugs during their fall. The two receiving trays 17 also serve to disperse the drugs. If the drugs fall directly onto the first drug discharge pipe 3 during the fall, it may cause an excessive amount of drugs in a local area, affecting the discharge of the drugs. By setting up two receiving trays 17, the drugs can be dispersed during the fall, and the rotation of the receiving trays 17 prevents the drugs from accumulating on the surface of the receiving trays 17, thus affecting the collection of drugs.
