Description

Technical Field

[0001] The present invention relates to the technical field of drug screening, and in particular to a device for screening western medicine drugs. Background Art

[0002] Drug screening refers to the process of using appropriate methods to evaluate the biological activity, pharmacological effects and medicinal value of substances (samples) that may be used as drugs. During the drug screening process, it is usually necessary to observe the situation inside the drug through a microscope according to the situation of the drug. When the inspector needs to screen drugs produced by multiple production lines. In order to separate different mixed drugs, currently, a drug screening device with a screen or filter plate is usually used, or drugs of different specifications are separated, and then the situation inside the drug is observed through professional optical instruments.

[0003] A Chinese patent discloses a western medicine drug screener (authorization announcement number CN110681566B), which drives the rotating shaft to rotate by turning the handle, thereby driving the screening cylinder to rotate, and aligning the filter plate with the smallest filter hole on the screening cylinder with the storage cavity below; then the medicine is added to the inside of the screening cylinder through the feeding pipe, and the smallest medicine leaks into the storage cavity through the filter plate with smaller filter holes, and after the smallest medicine is screened; the handle is turned, and the handle drives the rotating shaft to rotate, thereby driving the screening cylinder to rotate, and in turn driving other filter plates with gradually increasing filter holes to rotate to the top of the storage cavity, and at the same time, the rotating shaft rotates, and through the first belt linkage, drives the shaft rod to rotate, and through the cooperation of the first bevel gear and the second bevel gear, drives the round rod and the cylinder to rotate, and the cylinder rotates, and through the linkage of the second belt, drives the vertical rod and the storage box to rotate, and the other five storage cavities are rotated to the bottom of the filter plate in turn to achieve drug screening.

[0004] According to the above reference cases, the above device screens out medicines of different specifications by passing the sheet medicines through the filter plates with filter holes from small to large. In actual use, a single medicine screening is to place a large amount of medicines in the screening cylinder. When the medicine with a diameter larger than the filter hole fits the filter hole, the filter hole will be blocked by the medicine, and the medicine that meets the specifications will be blocked from passing through the filter hole, which will cause the medicine. The above device cannot always ensure the smooth flow of the filter hole, making it difficult to ensure that the medicine is fully screened. Summary of the invention

[0005] Based on this, it is necessary to provide a Western medicine drug screening device to address the problems of low screening efficiency and poor effect of existing Western medicine drug screening devices.

[0006] A western medicine drug screening device comprises a mounting frame, a screening cylinder is rotatably connected to the inner side of the mounting frame, a filter plate distributed in an annular shape is embedded and installed on the surface of the screening cylinder, the surface of the filter plate is provided with evenly distributed filter holes, and the inner diameters of the filter holes on different filter plates are all different, a collecting plate is rotatably connected to the inner side of the mounting frame, an adjusting mechanism fixedly connected to the collecting plate is fixedly connected between the mounting frame and the screening cylinder, and a dredging mechanism slidably connected to the screening cylinder is installed on the inner side of the mounting frame.

[0007] Furthermore, the adjustment mechanism includes a servo motor fixedly connected to the inner side of the mounting frame, the end of the servo motor output shaft is fixedly connected to the screening drum, the surface of the servo motor output shaft is sleeved with a driving bevel gear, the inner side of the driving bevel gear is provided with an arc groove, the inner side of the arc groove is slidably connected with a guide block fixedly connected to the surface of the servo motor output shaft, the surface of the driving bevel gear is meshingly connected with a driven bevel gear, and the bottom of the driven bevel gear is fixedly connected to a rotating shaft fixedly connected to a collecting plate.

[0008] In one of the embodiments, the adjustment mechanism can independently reciprocate the screening cylinder while maintaining the function of synchronously adjusting the position of the collection cup and the filter plate, so that the medicine inside the screening cylinder is shaken back and forth, which can cause the medicine in the screening cylinder to constantly change position to avoid large medicines clogging the filter holes, so that medicines that meet the specifications can pass through the filter holes and fall smoothly into the collection plate, thereby improving the effective screening rate of medicines that meet the specifications, so as to solve the problem of low screening efficiency and poor effect of existing Western medicine screening devices.

[0009] The filter element of the embodiment of the present invention is a kind of filter element with a kind of V-shaped grooves, each of which is parallel to the axis of the filter hole, and the two adjacent V-shaped grooves are connected. The opening of the V-shaped groove faces away from the axis of the filter hole. The surface of the filter hole is provided with circular arc guide grooves, which are distributed in an annular shape and are connected with the adjacent V-shaped grooves. The straight-line distance between the circular arc guide groove and the axis of the filter hole is the same as the straight-line distance between the two ends of the V-shaped groove facing away from the axis of the filter hole and the axis of the filter hole. The dredging mechanism comprises a guide bucket fixedly connected to the inner side of the mounting frame, the top and bottom ends of the guide bucket are respectively connected with the lowest filter plate and the collecting tray, the side end of the guide bucket is provided with a guide sliding mouth, the inside of the guide sliding mouth is slidably connected with a U-shaped rod, the two ends of the U-shaped rod are fixedly connected with sliders slidably connected with the adjacent V-shaped grooves, the surface of the U-shaped rod is fixedly connected with uniformly distributed dredging rods, and the top of the dredging rod passes through the inside of the adjacent filter hole.

[0010] In one of the embodiments, while the screening cylinder reciprocates and shakes the medicine, the dredging mechanism can not only guide the shaken and scattered medicine into the collection cup to prevent the medicine from being scattered everywhere, but also the screening cylinder can drive the dredging mechanism to reciprocate in and out of the corresponding filter holes through the V-shaped groove, which can push the medicine stuck in the filter hole back into the interior of the screening cylinder to ensure that the filter hole can filter and screen the medicine smoothly, further improving the effective screening rate of medicines that meet the specifications.

[0011] Furthermore, a protective cover is rotatably connected to the surface of the rotating shaft, the end of the servo motor output shaft passes through the protective cover, and the driving bevel gear and the driven bevel gear are both rotatably connected to the inside of the protective cover.

[0012] In one of the embodiments, the protective cover can limit the relative position of the driving bevel gear and the driven bevel gear under the vertical restraint of the servo motor output shaft and the rotating shaft to ensure that the driving bevel gear and the driven bevel gear can be effectively connected. At the same time, it can also effectively cover the driving bevel gear and the driven bevel gear therein to prevent external dust, debris and other impurities from falling onto the surface of the driving bevel gear or the driven bevel gear, so as to reduce the transmission resistance between the driving bevel gear and the driven bevel gear.

[0013] Furthermore, a rubber block is fixedly connected to the top of the dredging rod, and the shape of the rubber block is semicircular.

[0014] In one of the embodiments, a rubber block replaces the unblocking rod to flexibly push the medicine, thereby preventing the unblocking rod from scratching or crushing the medicine, thereby ensuring the integrity of the medicine.

[0015] Furthermore, the horizontal cross-sectional shapes of the guide sliding opening and the U-shaped rod and the sliding opening are all matching rectangles.

[0016] In one embodiment, this can prevent the U-shaped rod, the slider and the dredging rod from rotating to ensure that the dredging rod can enter and exit the filter hole normally.

[0017] Furthermore, the vertical cross-sectional shape of the filter plate is an arc shape, the fan-shaped angle of the filter plate is thirty degrees, and the fan-shaped angle of two adjacent filter plates is thirty degrees; the vertical cross-sectional shape of the guide bucket is an arc shape, and the fan-shaped angle of the guide bucket is ninety degrees; the fan-shaped angle of the guide block that can rotate and slide inside the arc groove is fifteen degrees.

[0018] In one of the embodiments, this not only ensures that the servo motor can drive the filter plate and the collection cup to adjust synchronously to ensure that the filter holes can be aligned with the corresponding collection cups, but also ensures that the servo motor can have a sufficient rotation angle to reciprocate the screening cylinder without touching the collection cups, thereby increasing the probability of screening the corresponding specifications of the medicine into the corresponding collection cups.

[0019] Furthermore, a fixing frame is fixedly connected to the inner side of the mounting frame, one end of the fixing frame penetrates into the interior of the screening cylinder, and a circular arc baffle plate that fits the inner wall of the screening cylinder is fixedly connected to the surface of the fixing frame; the cross-sectional shape of the circular arc baffle plate is fan-shaped, and the fan-shaped angle of the circular arc baffle plate is 320 degrees.

[0020] In one of the embodiments, this can prevent the medicine from splashing to the outside of the screening cylinder through the filter holes on the outside of the guide bucket during the reciprocating shaking of the screening cylinder, thereby reducing the waste of medicine.

[0021] The above-mentioned western medicine drug screening device, the adjustment mechanism can reciprocate the screening cylinder alone on the basis of maintaining the function of synchronously adjusting the position of the collection cup and the filter plate, so that the medicine inside the screening cylinder is reciprocated, which can make the medicine in the screening cylinder constantly change its position, so as to avoid large medicines blocking the filter holes, so that the medicines that meet the specifications can pass through the filter holes and fall into the collection plate smoothly, thereby improving the effective screening rate of the medicines that meet the specifications, so as to solve the problems of low screening efficiency and poor effect of the existing western medicine drug screening device;

[0022] While the screening cylinder reciprocates and shakes the medicine, the dredging mechanism can not only guide the shaken and scattered medicine into the collection cup to prevent the medicine from being scattered everywhere, but also the screening cylinder can drive the dredging mechanism to reciprocate in and out of the corresponding filter holes through the V-shaped groove, which can push the medicine stuck in the filter hole back into the interior of the screening cylinder to ensure that the filter hole can filter and screen the medicine smoothly, further improving the effective screening rate of medicines that meet the specifications.

[0039] Combine the following Figure 1 - Figure 8 The western medicine drug screening device of the present invention is described.

[0040] In one embodiment, a western medicine drug screening device includes a mounting frame 100, a screening cylinder 200 is rotatably connected to the inner side of the mounting frame 100, a filter plate 300 distributed in an annular shape is embedded and installed on the surface of the screening cylinder 200, and filter holes 310 distributed evenly are opened on the surface of the filter plate 300, and the inner diameters of the filter holes 310 on different filter plates 300 are all different, a collecting plate 400 is rotatably connected to the inner side of the mounting frame 100, an adjusting mechanism 500 fixedly connected to the collecting plate 400 is fixedly connected between the mounting frame 100 and the screening cylinder 200, and a dredging mechanism 600 slidably connected to the screening cylinder 200 is installed on the inner side of the mounting frame 100;

[0041] A controller electrically connected to the servo motor 510 is fixedly connected to the surface of the mounting frame 100. The collecting plate 400 includes a turntable rotatably connected to the inner side of the mounting frame 100. The center position of the top of the turntable is fixedly connected to the rotating shaft 550. The top of the turntable is provided with thread grooves distributed in a ring shape around the center position. The number of the thread grooves is the same as the number of the filter plate 300. The internal threads of the thread grooves are connected with thread columns. The top of the thread columns is fixedly connected with a collecting cup. One of the collecting cups is located directly below the lower opening of the guide bucket 610. The inner diameter ratio between the lower opening of the guide bucket 610 and the collecting cup is one to two.

[0042] When the staff needs to adjust the filter holes 310 with different inner diameters to filter and screen the corresponding specifications of the medicine, the staff controls the servo motor 510 through the controller to drive the screening cylinder 200 to rotate a specified angle, and the screening cylinder 200 rotates the filter plate 300 of the corresponding specification filter hole 310 to the bottom of the screening cylinder 200. At the same time, the servo motor 510 drives the active bevel gear 520 to rotate a specified angle through the guide block 530, and the active bevel gear 520 drives the driven bevel gear 540 to rotate toward each other at a specified angle, and the driven bevel gear 540 drives the rotating shaft 550 to rotate a specified angle, and the rotating shaft 550 drives the turntable to rotate a specified angle. The turntable drives all the collecting cups to rotate around the axis of the turntable at a specified angle through the threaded groove and the threaded column. When the filter plate 300 of the corresponding specification filter hole 310 rotates to the bottom of the screening cylinder 200, the corresponding collecting cup is just moved to the bottom of the guide bucket 610. At this time, the medicine of the corresponding specification can be guided by the guide bucket 610 to the collection cup for centralized storage after passing through the filter hole 310.

[0043] like Figure 2 , Figure 3 and Figure 7 As shown, the adjustment mechanism 500 includes a servo motor 510 fixedly connected to the inner side of the mounting frame 100, the end of the output shaft of the servo motor 510 is fixedly connected to the screening drum 200, the surface of the output shaft of the servo motor 510 is sleeved with a driving bevel gear 520, the inner side of the driving bevel gear 520 is provided with a circular arc groove 521, the inner side of the circular arc groove 521 is slidably connected with a guide block 530 fixedly connected to the surface of the output shaft of the servo motor 510, the surface of the driving bevel gear 520 is meshedly connected with a driven bevel gear 540, and the bottom of the driven bevel gear 540 is fixedly connected to the collecting plate 40. 0 is fixedly connected to the rotating shaft 550, and the adjusting mechanism 500 can independently reciprocate the screening cylinder 200 on the basis of maintaining the function of synchronously adjusting the positions of the collecting cup and the filter plate 300, so that the medicine inside the screening cylinder 200 is reciprocated, which can make the medicine in the screening cylinder 200 constantly change its position, so as to avoid large medicines from blocking the filter holes 310, so that the medicines that meet the specifications can pass through the filter holes 310 and fall into the collecting plate 400 smoothly, thereby improving the effective screening rate of the medicines that meet the specifications, so as to solve the problems of low screening efficiency and poor effect of the existing western medicine screening devices.

[0044] A protective cover 560 is rotatably connected to the surface of the rotating shaft 550, and the end of the output shaft of the servo motor 510 passes through the protective cover 560. The driving bevel gear 520 and the driven bevel gear 540 are both rotatably connected to the inside of the protective cover 560. The protective cover 560 can limit the relative position of the driving bevel gear 520 and the driven bevel gear 540 under the vertical restraint of the output shaft of the servo motor 510 and the rotating shaft 550, so as to ensure that the driving bevel gear 520 and the driven bevel gear 540 can be effectively connected. At the same time, it can also effectively cover the driving bevel gear 520 and the driven bevel gear 540 therein, preventing foreign dust, debris and other impurities from falling onto the surface of the driving bevel gear 520 or the driven bevel gear 540, so as to reduce the transmission resistance between the driving bevel gear 520 and the driven bevel gear 540.

[0045] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the spacing between the axis lines of two adjacent filter holes 310 is the same, the surface of the screening cylinder 200 is provided with V-shaped grooves 210 that are evenly distributed and parallel to the axis lines of the adjacent filter holes 310, the two adjacent V-shaped grooves 210 are connected, and the openings of the V-shaped grooves 210 are facing away from the axis line of the screening cylinder 200, and the surface of the screening cylinder 200 is provided with circular arc guide grooves 220 that are distributed in an annular shape and are connected to the adjacent V-shaped grooves 210, respectively, and the straight-line distance between the circular arc guide grooves 220 and the axis line of the screening cylinder 200 is the same as the straight-line distance between the two ends of the V-shaped grooves 210 facing away from the axis line of the screening cylinder 200 and the axis line of the screening cylinder 200, and the dredging mechanism 600 includes a guide bucket 610 fixedly connected to the inner side of the mounting frame 100, the top and bottom ends of the guide bucket 610 are respectively connected to the lowest filter plate 300 and the collecting tray 400, and the side ends of the guide bucket 610 are provided with guide slides The U-shaped rod 620 is slidably connected to the inside of the guide sliding mouth 611, and both ends of the U-shaped rod 620 are fixedly connected to sliders 630 slidably connected to the adjacent V-shaped groove 210. The surface of the U-shaped rod 620 is fixedly connected to uniformly distributed dredging rods 640, and the top of the dredging rod 640 penetrates into the inside of the adjacent filter hole 310. When the screening cylinder 200 reciprocates and shakes the medicine, the dredging mechanism 600 can not only guide the shaken and scattered medicine into the collection cup to prevent the medicine from being scattered everywhere, but also the screening cylinder 200 can drive the dredging mechanism 600 to reciprocate in and out of the corresponding filter hole 310 through the V-shaped groove 210, which can push the medicine stuck in the filter hole 310 back into the inside of the screening cylinder 200 to ensure that the filter hole 310 can filter and screen the medicine smoothly, further improving the effective screening rate of medicines that meet the specifications.

[0046] The top of the dredging rod 640 is fixedly connected with a rubber block 650, and the shape of the rubber block 650 is semicircular; the horizontal cross-sectional shapes of the guide slide 611 and the U-shaped rod 620 and the slide 611 are all matched rectangles; the vertical cross-sectional shape of the filter plate 300 is an arc shape, the fan-shaped angle of the filter plate 300 is thirty degrees, and the fan-shaped angle of two adjacent filter plates 300 is thirty degrees; the vertical cross-sectional shape of the guide bucket 610 is an arc shape, and the fan-shaped angle of the guide bucket 610 is thirty degrees. The included angle is ninety degrees; the fan-shaped included angle of the guide block 530 that can rotate and slide inside the arc groove 521 is fifteen degrees; the inner side of the mounting frame 100 is fixedly connected with a fixing frame 700, one end of the fixing frame 700 penetrates into the interior of the screening cylinder 200, and the surface of the fixing frame 700 is fixedly connected with an arc baffle 800 that fits the inner wall of the screening cylinder 200; the cross-sectional shape of the arc baffle 800 is fan-shaped, and the fan-shaped included angle of the arc baffle 800 is three hundred and twenty degrees;

[0047] When the slider 630 moves along the V-shaped groove 210 from the position closest to the axis of the screening cylinder 200 in the direction away from the axis of the screening cylinder 200, the slider 630 drives all the clearing rods 640 to move to the outside of the filter hole 310 through the U-shaped rod 620. Before the U-shaped rod 620 contacts the filter hole 310, the slider 630 can completely move the clearing rod 640 to the outside of the filter hole 310 to avoid direct contact between the U-shaped rod 620 and the filter hole 310, thereby ensuring that the screening cylinder 200 can shake the medicine smoothly.

[0048] Working principle: When the medicine is filtered through the filter holes 310 on the filter plate 300, the staff can control the servo motor 510 to move back and forth according to the needs, and the servo motor 510 drives the screening cylinder 200 to rotate back and forth, and the screening cylinder 200 drives all the medicines inside it to swing back and forth. In this process, the medicine swings back and forth inside the screening cylinder 200, which can make the medicine in the screening cylinder 200 constantly change its position to avoid large medicines blocking the filter holes 310, so that the medicines that meet the specifications can pass through the filter holes 310 and fall into the collection plate 400 smoothly, thereby improving the effective screening rate of medicines that meet the specifications;

[0049] During the reciprocating rotation of the screening cylinder 200, the screening cylinder 200 synchronously drives all the V-grooves 210 and the circular arc guide grooves 220 to reciprocate. At this time, the V-groove 210 synchronously guides the slider 630. Since the slide 611 prevents the slider 630 from following the circular arc movement of the V-groove 210 through the U-shaped rod 620, the slider 630 can only be vertically guided by the V-groove 210 to approach or move away from the axis of the screening cylinder 200. When the slider 630 is guided to the position closest to the axis of the screening cylinder 200, the slider 630 drives the dredging rod 640 through the U-shaped rod 620 to penetrate into the filter hole 310, and actively pushes the medicine stuck in the filter hole 310 back into the inside of the screening cylinder 200, so as to ensure that the filter hole 310 can filter and filter the medicine smoothly.

[0050] It should be noted that the controller and servo motor 510 in the above description are both relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the controller and servo motor 510 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0051] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
