Technical Field
[0001] The utility model relates to the technical field of drug screening, in particular to a screening device with an anti-blocking function. Background Art
[0002] Drugs are substances used to prevent, treat and diagnose diseases. In theory, drugs refer to any chemical substance that can affect the physiological functions of the body's organs and the metabolic activities of cells. Drugs only affect the speed of the body's biological functions and cannot change existing natural biological processes or produce new functions. For example, drugs can speed up or slow down the biochemical reactions that cause muscle contraction, the regulation of water and sodium retention and excretion by kidney cells, the secretion of glands (such as mucus, gastric acid or), and the transmission of information by nerves. The strength of the drug's effect generally depends on the response of the target site, and drug raw materials are one of the important components of drug production.
[0003] At present, when the pharmaceutical raw materials on the market are produced and processed, screening devices are needed to screen the pharmaceutical raw materials. In actual use, when the screening device screens the pharmaceutical raw materials, most of them will screen the pharmaceutical raw materials through a screening net. When the screening net is used for a long time, the screening mesh inside the screening net is easily blocked by the pharmaceutical raw materials, thereby reducing the subsequent filtering and screening efficiency of the screening net, and further causing the subsequent screening device to reduce the screening efficiency of the pharmaceutical raw materials.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a screening device with anti-blocking function, and the technical solution is as follows:
[0023] A screening device with an anti-blocking function comprises a cylinder 1 and a closed door 2 hinged on the outer wall of the cylinder 1, a screening slot 3 is opened inside the cylinder 1, a screening net 4 is connected to the inside of the screening slot 3 by bolts, a fixed plate 5 is provided at the bottom end of the screening net 4, one end of the fixed plate 5 is fixedly connected to the inside of the screening slot 3, a moving rod 6 passes through the inside of the fixed plate 5, the moving rod 6 is slidably connected to the fixed plate 5, a knocking plate 7 is fixedly connected to the top of the moving rod 6, a first magnet 8 is fixedly connected to the inside of the knocking plate 7, a driving shaft 9 is provided inside the screening slot 3, a rotating block 10 is fixedly connected to the outer wall of the driving shaft 9, a first rotating plate 11 is fixedly connected to the outer wall of the rotating block 10, and a second magnet 12 is fixedly connected to the inside of the first rotating plate 11.
[0024] In a preferred embodiment, a second rotating plate 13 is fixedly connected to the outer wall of the rotating block 10 away from the first rotating plate 11, and a third magnet 14 is fixedly connected to the outer wall of the second rotating plate 13. When the rotating block 10 moves, the rotating block 10 can drive the first rotating plate 11 to move, so that the first rotating plate 11 can drive the second magnet 12 to move.
[0025] In a preferred embodiment, the top end of the driving shaft 9 passes through the outer wall of the cylinder 1 and the driving shaft 9 is rotatably connected to the cylinder 1. A motor 15 is fixedly connected to the top of the cylinder 1. When the rotating block 10 moves, the rotating block 10 can drive the second rotating plate 13 to move, so that the second rotating plate 13 can drive the third magnet 14 to move.
[0026] In a preferred embodiment, one end of the output shaft of the motor 15 is fixedly connected to the driving shaft 9, and a feed pipe 16 is fixedly connected to the outer wall of the cylinder 1 away from the closing door 2. When the first magnet 8 moves, the first magnet 8 can drive the knocking plate 7 to move, so that the knocking plate 7 can move inside the screening slot 3.
[0027] Working principle of the utility model: when the device is used and the medicine needs to be screened, the medicine raw material is allowed to enter the screening slot 3 from the feed pipe 16, and the medicine raw material reaches the top of the screening net 4. At this time, the motor 15 is started, and the output shaft of the motor 15 drives the driving shaft 9 to move, so that the driving shaft 9 rotates inside the screening slot 3, and the driving shaft 9 drives the rotating block 10 to move, so that the rotating block 10 rotates inside the screening slot 3, and the rotating block 10 can drive the first rotating plate 11 to move, so that the first rotating plate 11 moves in a circular motion inside the screening slot 3, and the rotating block 10 drives the second rotating plate 13 to move at the same time, so that the second rotating plate 13 moves in a circular motion inside the screening slot 3, and the first rotating plate 11 can drive the second magnet 12 to move, so that the second magnet 12 moves in a circular motion inside the screening slot 3, and the second rotating plate 13 can drive the third magnet 14 to move, so that the third magnet 14 moves in the screening slot 3. The first rotating plate 11 and the second rotating plate 13 can stir the drug raw materials on the top of the screening mesh 4 during the internal circular motion. When the second magnet 12 reaches directly above the first magnet 8, the first magnet 8 and the second magnet 12 attract each other, causing the first magnet 8 to move upward. The first magnet 8 can drive the knocking plate 7 to move, so that the knocking plate 7 can drive the moving rod 6 to move, so that the moving rod 6 slides inside the screening slot 3. The moving rod 6 slides with the fixed plate 5 at the same time, and the top of the knocking plate 7 will contact the screening mesh 4 instantaneously, causing the screening mesh 4 to vibrate, thereby allowing the blockages in the internal mesh of the screening mesh 4 to be shaken out. When the third magnet 14 reaches directly above the first magnet 8, the third magnet 14 and the first magnet 8 repel each other, causing the knocking plate 7 to move away from the screening mesh 4, causing the subsequent knocking plate 7 to intermittently knock on the screening mesh 4, thereby reducing the blockage rate of the internal mesh of the screening mesh 4.
[0028] See also Figure 1 and Figure 2The utility model provides a technical solution: a fixed block 17 is fixedly connected to the bottom end of the cylinder 1, and a threaded rod 18 is rotatably connected to the bottom end of the fixed block 17. When the knocking plate 7 moves, the knocking plate 7 can drive the moving rod 6 to move, so that the moving rod 6 and the fixed plate 5 slide.
[0029] In a preferred embodiment, a support column 19 is provided at the bottom end of the threaded rod 18, and an adjustment groove 20 is opened at the top of the support column 19. The threaded rod 18 is connected to the adjustment groove 20 through a thread. When the threaded rod 18 moves, the threaded rod 18 can move inside the adjustment groove 20, so that the threaded rod 18 can move with the adjustment groove 20 through the thread.
[0030] The working principle of the utility model is as follows: when the device is used and the height of the equipment needs to be adjusted, the threaded rod 18 is rotated to rotate the threaded rod 18 and the fixed block 17, and the bottom end of the threaded rod 18 moves inside the adjustment groove 20 at the same time, so that the threaded rod 18 and the adjustment groove 20 move through the thread phase, thereby changing the position of the threaded rod 18 inside the adjustment groove 20, thereby facilitating adaptive changes in the distance between the support column 19 and the fixed block 17.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
