Drugs include various medicines such as hypnotics, cold medicines, fever reducers, stomach medicines, and laxatives, which are beneficial to health.

[0003] In the pharmaceutical industry, some drugs need to be extruded into granules.

[0010] Preferably, the collecting mechanism includes side plates, the lower end of which is symmetrically fixedly connected to the four corners of the upper ends of filter frame one and filter frame two. A lead screw is rotatably installed on the inner side of one set of side plates, and a motor two is fixedly installed at the rear end of the side plates. A guide rod is fixedly installed on the inner side of the other set of side plates. A threaded plate is installed on the external thread of the lead screw, and a guide plate is slidably installed on the external side of the guide rod. A pusher plate is movably installed at the rear end of filter frame one and filter frame two. A discharge port is opened through the front end of filter frame one and filter frame two. An insertion port is opened on the upper side of the front end of filter frame one and filter frame two. Positioning blocks are symmetrically fixed on the inner walls of the insertion port and the discharge port. A baffle is movably inserted into the inside of the insertion port and the discharge port. Positioning grooves are opened inside both ends of the baffle.

[0011] Preferably, the top end of the lead screw is driven and installed at the output end of the second motor, the threaded plate and the guide plate are both L-shaped, the pusher plate is in contact with the rear side of the inner cavity of the filter frame, and the bottom ends of the threaded plate and the guide plate are symmetrically fixedly connected to the upper ends of the pusher plate on both sides.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention provides a drug particle screening device. Through a vibration mechanism, the drug particles to be screened are first poured into a first filter frame, which filters the particles, blocking unqualified particles. Qualified particles fall into a second filter frame for further screening, with unqualified particles again being blocked. Qualified particles then fall into a lower collection frame. This process completes the screening and collection of qualified particles. The multi-layered filter frames improve the screening effect. A rotating rod drives a cam to rotate, and the cam's protrusion pushes the first and second filter frames forward. The filter frames then cause the mounting block to slide synchronously on a sliding rod, compressing a spring. After the cam separates from the filter frame, the spring's elasticity allows the filter frame to reciprocate back and forth on the sliding rod. This reciprocating motion of the filter frame quickly and effectively screens the drug particles, resulting in high screening efficiency and good performance.

[0017] This invention provides a drug particle screening device. Through a collection mechanism, filter frames one and two, during particle screening, obstructs unqualified particles, keeping them within the filter frames. When collection is needed, a baffle is raised to open the discharge port. A rotating screw then moves a threaded plate forward, which, with the assistance of a guide plate, drives a pusher plate within the filter frames to move synchronously. This pusher plate pushes the unqualified particles forward, allowing them to be quickly discharged into collection frame one through the discharge port. This process completes the collection of unqualified particles and allows for the rapid screening of three groups of drug particles of different sizes. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to embodiments:

[0025] like Figures 1-5 As shown, this utility model provides a drug particle screening device, including a base plate 1, with uprights 2 symmetrically fixed at the four corners of the upper end of the base plate 1, a vibration mechanism 3 at the rear end of the uprights 2, a filter frame 4 at the upper inner side of the uprights 2, a filter frame 5 directly below the filter frame 4, a collection frame 6 fixedly fixed at the lower front end of both the filter frame 4 and the filter frame 5, and a collection mechanism 7 inside both the filter frame 4 and the filter frame 5. A positioning plate 8 is fixedly fixed at the middle of the upper end of the base plate 1, and a collection frame 9 is movably mounted inside the positioning plate 8.

[0026] The positioning plate 8 is U-shaped, and the collection frame is located directly below the filter frame 5. The collection frame 6 is connected to the interior of the filter frame through the discharge port 78.

[0027] The filter holes on filter frame 4 and filter frame 5 have different sizes.

[0028] In this solution, the design of multi-layer filter frames and the graded screening method significantly improve the accuracy and effectiveness of particle screening. Through collection frame 1 (6) and collection frame 2 (9), unqualified drug particles and qualified drug particles can be collected separately.

[0029] like Figures 3-4 As shown, the vibration mechanism 3 includes a motor 31. The lower end of the motor 31 is fixedly connected to one side of the rear end of the base plate 1. A pulley 32 is fixedly mounted on the top of the output rod of the motor 31. A fixed seat 33 is fixedly mounted in the middle of the rear end of the base plate 1. A rotating rod 34 is rotatably mounted on the fixed seat 33. A pulley 35 is fixedly sleeved on the lower end of the rotating rod 34. A belt 36 is sleeved between the pulley 32 and the pulley 35. Two sets of equidistantly distributed cams 37 are fixedly sleeved on the upper end of the rotating rod 34. Slide rods 38 are fixedly fixedly mounted on the inner side of the support frame 2 at equal intervals. Mounting blocks 39 are symmetrically fixed at both ends of the filter frame 4 and the filter frame 5. A spring 310 is sleeved on the front end of the slide rod 38.

[0030] The interior of the mounting block 39 is slidably mounted to the rear end of the slide bar 38, and the two ends of the spring 310 are fixedly connected to the opposite surfaces of the stand 2 and the mounting block 39, respectively.

[0031] Cam 37 is located at the rear end of filter frame 4 and filter frame 5, and the top of cam 37 is in active contact with the rear end of filter frame 4 and filter frame 5.

[0032] In this scheme, the reciprocating motion of filter frame 4 and filter frame 5 greatly improves the screening efficiency. Compared with traditional screening methods, it can process more drug particles in a shorter time and achieve better screening results, ensuring the consistency and stability of drug particle size during the drug production process.

[0033] like Figure 5 As shown, the collecting mechanism 7 includes side plates 71. The lower end of the side plates 71 is symmetrically fixedly connected to the four corners of the upper end of filter frame 4 and filter frame 5. A lead screw 72 is rotatably installed on the inner side of one set of side plates 71. A motor 73 is fixedly installed at the rear end of the side plates 71. A guide rod 74 is fixedly installed on the inner side of the other set of side plates 71. A threaded plate 75 is installed on the external thread of the lead screw 72. A guide plate 76 is slidably installed on the external side of the guide rod 74. A pusher plate 77 is movably installed at the rear end of the filter frame 4 and filter frame 5. A discharge port 78 is opened through the front end of the filter frame 4 and filter frame 5. An insertion port 79 is opened on the upper side of the front end of the filter frame 4 and filter frame 5. Positioning blocks 710 are symmetrically fixed on the inner walls of the insertion port 79 and the discharge port 78. A baffle 711 is movably inserted into the insertion port 79 and the discharge port 78. Positioning grooves 712 are opened inside both ends of the baffle 711.

[0034] The top end of the lead screw 72 is connected to the output end of the motor 73 for transmission. The threaded plate 75 and the guide plate 76 are both L-shaped. The pusher plate 77 is attached to the rear side of the inner cavity of the filter frame. The bottom ends of the threaded plate 75 and the guide plate 76 are symmetrically fixed to the upper ends of the pusher plate 77.

[0035] The top end of the lead screw 72 is connected to the output end of the motor 73 for transmission. The threaded plate 75 and the guide plate 76 are both L-shaped. The pusher plate 77 is attached to the rear side of the inner cavity of the filter frame. The bottom ends of the threaded plate 75 and the guide plate 76 are symmetrically fixed to the upper ends of the pusher plate 77.

[0036] In this design, the baffle 711 can be inserted directly into the outlet 78 through the insertion port 79, thereby sealing the outlet 78 and allowing the filter frame 4 and filter frame 5 to be used for normal screening. The guide plate 76 can slide on the guide rod 74, thereby improving the stability of the pusher plate 77. After the pusher plate 77 has finished pushing the material, it can be reset to avoid affecting the screening of drug particles.

[0037] The working principle of this drug particle screening device will be explained in detail below.

[0038] like Figures 1-5 As shown, in use, the drug particle screening device works as follows: The operator pours the drug particles to be screened into the uppermost filter frame 4. Filter frame 4 performs initial screening, blocking particles with sizes that do not meet the requirements. Particles with the correct size pass through the screen and fall into the lower filter frame 5. The screen in filter frame 5 further screens the particles, blocking those that do not meet the requirements again. Only particles that meet both screening criteria can pass through filter frame 5. The sieve at position 5 eventually falls into the bottom collection frame 2, 9, thus completing the screening and collection of qualified particles. During the screening process, motor 1, 31 can be started. The output rod of motor 1, 31 can drive pulley 1, 32 to rotate, and pulley 1, 32 can drive pulley 2, 35 to rotate via belt 36, thus ensuring that the rotating rod 34 rotates synchronously. As the rotating rod 34 drives the cam 37 to rotate continuously, the protruding part of the cam 37 gradually approaches the filter frame 1, 4 and the filter frame 2, 5, and applies a forward thrust to them. After being pushed, the filter frame 1, 4 and the filter frame 2, 5 will drive the mounting block 39 to slide forward along the slide rod 38. During this process, spring 310 is gradually compressed. When the protrusion of cam 37 separates from the filter frame, the elastic potential energy stored in spring 310 is released. Under the strong elastic restoring force of spring 310, filter frames 4 and 5 move backward along slide rod 38. This process is repeated, and the filter frames reciprocate back and forth on slide rod 38 at a high frequency, causing the drug particles inside the filter frames to vibrate continuously. Under the action of vibration, the particles can make more full contact with the screen, completing the sieving process quickly and effectively. After the drug particles have been screened, unqualified particles remain in filter frames 4 and 5. At this point, the baffle 711 can be lifted to separate it from the discharge port 78, thereby opening the discharge port 78. Then, the second motor 73 can be started, which drives the lead screw 72 to rotate. The lead screw 72 then drives the threaded plate 75 to move forward, so that the threaded plate 75 can drive the pusher plate 77 in the filter frame to move synchronously through the guide plate 76. The pusher plate 77 pushes the unqualified particles in the filter frame forward with a stable thrust. Under the action of the pusher plate 77, these particles quickly pass through the discharge port 78 and are accurately discharged into the collection frame 6, thereby quickly completing the collection of unqualified drug particles.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
