[0004] The following problems exist during the actual use of the above patent: 1. The medicine in the arc plate can be ground by the rotation and vertical movement of the grinding wheel and the protrusion, but the vertical movement of the grinding wheel and the cam will squeeze the medicine in the arc plate to move to both sides, so that part of the medicine is retained on both sides of the arc plate and cannot be ground by the grinding wheel and the protrusion, resulting in incomplete grinding; 2. After a long period of grinding, the filter holes on the arc plate will be clogged, which will affect the filtering effect. Therefore, the filter holes need to be cleaned regularly, which increases the workload of the staff and the cleaning work is cumbersome. Summary of the invention

[0005] The present invention is intended to provide a pediatric medicine grinding device to solve the problem that the existing grinding devices do not fully grind the medicine.

[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a pediatric drug grinding device, comprising a box body, on which a feed port and a discharge port are provided; a partition is provided in the box body, on which a rotating shaft is rotatably connected, and grinding rollers are coaxially connected on both sides of the rotating shaft located on the partition; a through groove is provided on the partition, and the through groove is located below the rotating shaft; a movable plate is vertically slidably connected in the through groove, and the two ends of the movable plate are in frictional contact with the inner walls of the two sides of the box body; auxiliary mechanisms are provided on both sides of the movable plate located on the partition, and the auxiliary mechanisms include a filter part and an auxiliary part, and the filter The first part includes a plurality of filter holes equidistantly arranged on the movable plate; the auxiliary part includes a first slide groove and a second slide groove arranged on the movable plate, and the filter holes are located between the first slide groove and the second slide groove; a block for blocking the through groove is slidably connected in the first slide groove, and a push block is slidably connected in the second slide groove, and the movement direction of the block is opposite to that of the push block; it also includes a driving mechanism for driving the rotation of the rotating shaft, a power mechanism for driving the vertical movement of the movable plate as the rotating shaft rotates, and an adjustment mechanism for adjusting the distance between the block and the push block on both sides of the partition at the same time as the rotating shaft rotates.

[0007] The principles and advantages of this solution are:

[0008] 1. This solution can grind the medicine on the movable plate by rotating the grinding roller, so that the medicine powder of qualified size falls to the bottom of the box through the filter hole. Compared with the existing technology, during the rotation of the shaft, the adjustment mechanism can adjust the block and the push block to move closer or farther, thereby driving the movement of the medicine on the movable plate, and then continuously changing the position of the medicine, promoting uniform grinding of all the medicines.

[0009] 2. In this solution, both sides of the partition can grind the medicine so that more medicines can be grinded in the same time, thereby improving the grinding efficiency.

[0010] 3. In this solution, the movable plate moves vertically, so that the movable plate is close to and away from the grinding roller. On the one hand, it can promote the grinding process of the medicine, and on the other hand, it can drive the medicine to turn over, thereby continuously changing the position of the medicine, and promoting uniform grinding of all the medicines.

[0011] Furthermore, the power mechanism includes a chamber opened in the partition, a cam body coaxially connected to the rotating shaft, and a C-shaped block fixed to the movable plate. The rotating shaft passes through the chamber, and the cam body and the C-shaped block are both located in the chamber, and the cam body is simultaneously against both ends of the C-shaped block.

[0012] Through the above arrangement, during the rotation of the shaft, the shaft drives the cam body to rotate in the C-shaped block, so that the C-shaped block reciprocates vertically in the chamber, thereby driving the movable plate to reciprocate vertically in the through slot.

[0013] Furthermore, the adjustment mechanism includes a cylindrical cam coaxially connected to the rotating shaft and located on both sides of the partition, side grooves opened on both sides of the partition, a first spring connecting the first slide groove and the block, and a second spring connecting the second slide groove and the push block. The cylindrical cam is provided with a curved groove, and the first adjustment block and the second adjustment block are slidably connected in the curved groove. The side groove is communicated with the chamber, the first adjustment block is laterally slidably connected to the side groove, the first adjustment block can move laterally in the chamber, the second adjustment block is laterally slidably connected to the box body, the free end of the first adjustment block passes through the side groove, and the through groove is arranged toward the direction of the block, the block is located on the movement trajectory of the free end of the first adjustment block, and the push block is located on the movement trajectory of the second adjustment block.

[0014] Through the above arrangement, during the rotation of the rotating shaft, the rotating shaft drives the cylindrical cam to rotate, and the first adjusting block and the second adjusting block approach and move away under the guidance of the curved groove; when the movable plate moves downward, the first adjusting block and the second adjusting block approach, the first adjusting block squeezes the block to slide in the first slide groove, and the first spring stretches; at the same time, the second adjusting block squeezes the push block to slide in the second slide groove, and the second spring stretches, that is, the block and the push block approach each other, at this time the movable plate is separated from the grinding roller, so as to drive the medicines on the movable plate to move to the bottom of the grinding roller in a centralized manner, so as to grind the medicines in a centralized manner. When the movable plate moves upward, the first adjusting block and the second adjusting block move away from each other, the squeezing effect of the first adjusting block on the block disappears, and the squeezing effect of the second adjusting block on the push block disappears, so that the block moves in the opposite direction under the action of the first spring, and the push block moves in the opposite direction under the action of the second spring, that is, the baffle and the push block move away, and at this time the movable plate is close to the grinding roller.

[0015] Furthermore, the movable plate is provided with transverse grooves on both sides of the partition, and the transverse grooves are communicated with the filter holes; a transverse block is slidably connected in the transverse groove, and a number of guide holes that can communicate with the filter holes are equidistantly provided on the transverse block, and the guide holes and the filter holes are staggered; it also includes a reciprocating mechanism for simultaneously driving the two transverse blocks to move back and forth horizontally.

[0016] Through the above arrangement, during the movement of the transverse block, when the guide hole and the filter hole are staggered, the grinding roller can concentrate on grinding the medicine; when the guide hole and the filter hole are connected, the medicine powder with qualified size after grinding falls to the bottom of the box through the filter hole and the guide hole; and the reciprocating movement of the transverse block in the transverse groove can clean the filter hole, avoid clogging of the filter hole, and ensure the filtering effect.

[0017] Furthermore, the reciprocating mechanism includes inclined grooves opened on both sides of the inner wall of the chamber and wall grooves opened laterally on the side walls of the transverse block. The spacing between the two inclined grooves gradually decreases from top to bottom. A slider is slidably connected in the inclined groove. The end of the slider away from the inclined groove passes through the wall groove and is fixed to the transverse block. The slider is slidably connected to the wall groove.

[0018] Through the above arrangement, when the movable plate moves upward, the movable plate drives the transverse block and the slider to move upward. Since the slider moves along the path of the inclined groove, the slider drives the transverse block to move laterally in the transverse groove. At the same time, the slider moves laterally in the wall groove, so that the two transverse blocks are close to each other, so that the guide hole and the filter hole are staggered, so that the grinding roller can perform centralized grinding processing on the medicine; when the movable plate moves downward, the movable plate drives the transverse block and the slider to move downward. Since the slider moves along the path of the inclined groove, the slider drives the transverse block to move laterally in the opposite direction in the transverse groove. At the same time, the slider moves laterally in the opposite direction in the wall groove, so that the two transverse blocks are separated, so that the guide hole and the filter hole are connected, and the medicine powder with qualified size after grinding falls to the bottom of the box through the filter hole and the guide hole.

[0019] Furthermore, cleaning mechanisms are provided on both sides of the box body, and the cleaning mechanisms include a plurality of cleaning blocks for extending into the filter holes and the guide holes, the cleaning blocks are fixedly connected to the inner wall of the box body, and the cleaning blocks are located below the movable plate.

[0020] Through the above arrangement, when the movable plate moves upward, the movable plate moves away from the cleaning block; when the movable plate moves downward, the guide hole is connected to the filter hole, and the cleaning block extends into the guide hole and the filter hole to clean them, thereby avoiding blockage of the guide hole and the filter hole and ensuring the filtering effect.

[0021] Further, the width of the cleaning block gradually increases from top to bottom.

[0022] Through the above arrangement, on the one hand, it is convenient for the top of the cleaning block to extend into the guide hole and the filter hole, and on the other hand, the cleaning effect of the guide hole and the filter hole can be enhanced.

[0023] Furthermore, side grooves are horizontally provided on both sides of the inner wall of the box body, and strip blocks are slidably connected in the side grooves. A third spring is provided between the strip block and the side grooves, and a number of impact blocks for impacting the cleaning blocks are equidistantly provided on the strip block; a first wedge block is provided on the top of the strip block; second wedge blocks for squeezing the first wedge block are provided on both sides of the bottom of the movable plate, and the first wedge block is located on the movement trajectory of the second wedge block.

[0024] Through the above arrangement, when the movable plate moves upward, the first wedge block and the second wedge block move away from each other; when the movable plate moves downward, the second wedge block squeezes the first wedge block to drive the strip block to move laterally, that is, the two strip blocks are close to each other and the third spring is compressed; during the lateral movement of the strip block, the strip block drives the impact block to move synchronously, so that the impact block hits the cleaning block, and the cleaning block vibrates. At this time, the cleaning block is located in the guide hole and the filter hole, thereby enhancing the cleaning effect of the guide hole and the filter hole; and the vibration of the cleaning block can also allow the drug powder on the surface of the cleaning block to detach, thereby improving the recovery rate of the drug powder.

[0025] Furthermore, the stopper is provided with a first sealing plate for blocking the first slide groove, and the first sealing plate is in frictional contact with the top of the movable plate; the push block is provided with a second sealing plate for blocking the second slide groove, and the second sealing plate is in frictional contact with the top of the movable plate.

[0026] Through the above arrangement, during the reciprocating motion of the block, the block drives the first sealing plate to move synchronously, and the first sealing plate always blocks the first slide groove to prevent the medicine from falling into the first slide groove; similarly, during the reciprocating motion of the push block, the push block drives the second sealing plate to move synchronously, and the second sealing plate always blocks the second slide groove to prevent the medicine from falling into the second slide groove.

[0041] The specific implementation process is as follows:

[0042] When in use, the medicine is put into the box body 10 through the feed port 11, and the medicine is divided into two parts by the inclined surfaces on both sides of the top of the partition 13, and falls on the movable plates 24 on both sides of the partition 13 respectively; then the motor 22 is started, and the output shaft of the motor 22 drives the rotating shaft 20 to rotate, and the rotating shaft 20 drives the grinding roller 21 to rotate, and the grinding roller 21 grinds the medicine on the movable plate 24.

[0043] During the rotation of the rotating shaft 20, the rotating shaft 20 drives the cam body 31 to rotate in the C-shaped block 32, so that the C-shaped block 32 makes vertical reciprocating motion in the chamber 30, thereby driving the movable plate 24 to make vertical reciprocating motion in the through groove 23; and, during the vertical reciprocating motion of the movable plate 24, the through groove 23 can be blocked by the block 28 to prevent the medicine from falling into the through groove 23; when the movable plate 24 moves upward, the movable plate 24 is close to the grinding roller 21 to grind the medicine; when the movable plate 24 moves downward, the movable plate 24 is away from the grinding roller 21.

[0044] During the rotation of the rotating shaft 20, the rotating shaft 20 drives the cylindrical cam 40 to rotate, and the first adjusting block 45 and the second adjusting block 46 approach and move away under the guidance of the curved groove 44; when the movable plate 24 moves downward, the first adjusting block 45 and the second adjusting block 46 approach each other, and the first adjusting block 45 squeezes the stopper 28 to slide in the first slide groove 26, and the first spring 42 is stretched; at the same time, the second adjusting block 46 squeezes the push block 29 to slide in the second slide groove 27, and the second spring 43 is stretched, so that the stopper 28 and the push block 29 approach each other, and the movable plate 24 is separated from the grinding roller 21 at this time, so that the medicines on the movable plate 24 can be driven to move to the bottom of the grinding roller 21 in a concentrated manner, so as to carry out a concentrated grinding process on the medicines. When the movable plate 24 moves upward, the first adjusting block 45 and the second adjusting block 46 move away from each other, the squeezing effect of the first adjusting block 45 on the stopper 28 disappears, and the squeezing effect of the second adjusting block 46 on the push block 29 disappears, so that the stopper 28 moves in the opposite direction under the action of the first spring 42, and the push block 29 moves in the opposite direction under the action of the second spring 43, that is, the baffle plate and the push block 29 move away from each other, and the movable plate 24 approaches the grinding roller 21 at this time; in addition, the approach and distance of the stopper 28 and the push block 29 can drive the movement of the medicine on the movable plate 24, so as to continuously change the position of the medicine and promote uniform grinding of all the medicines.

[0045] During the reciprocating motion of the block 28, the block 28 drives the first sealing plate 47 to move synchronously, and the first sealing plate 47 always blocks the first slide groove 26 to prevent the medicine from falling into the first slide groove 26; similarly, during the reciprocating motion of the push block 29, the push block 29 drives the second sealing plate 48 to move synchronously, and the second sealing plate 48 always blocks the second slide groove 27 to prevent the medicine from falling into the second slide groove 27.

[0046] When the movable plate 24 moves upward, the movable plate 24 drives the transverse block 51 and the slider 55 to move upward. Since the slider 55 moves along the path of the inclined groove 53, the slider 55 drives the transverse block 51 to move laterally in the transverse groove 50. At the same time, the slider 55 moves laterally in the wall groove 54, so that the two transverse blocks 51 are close to each other, so that the guide hole 52 and the filter hole 25 are staggered, so that the grinding roller 21 can grind the medicine in a centralized manner; when the movable plate 24 moves downward, the movable plate 24 drives the transverse block 51 and the slider 55 to move downward. Since the slider 55 moves along the inclined groove 53, the slider 55 drives the transverse block 51 to move laterally in the transverse groove 50. At the same time, the slider 55 moves laterally in the wall groove 54, so that the two transverse blocks 51 are close to each other, so that the guide hole 52 and the filter hole 25 are staggered, so that the grinding roller 21 can grind the medicine in a centralized manner. The path movement of the inclined groove 53 causes the slider 55 to drive the transverse block 51 to move in the opposite transverse direction in the transverse groove 50. At the same time, the slider 55 moves in the opposite transverse direction in the wall groove 54, so that the two transverse blocks 51 move away from each other, so that the guide hole 52 is connected with the filter hole 25, and the drug powder with qualified size after grinding falls to the bottom of the box body 10 through the filter hole 25 and the guide hole 52, and finally moves out from the discharge port 12; in addition, the reciprocating movement of the transverse block 51 in the transverse groove 50 can clean the filter hole 25, avoid clogging of the filter hole 25, and ensure the filtering effect.

[0047] When the movable plate 24 moves upward, the movable plate 24 moves away from the cleaning block 60; when the movable plate 24 moves downward, the guide hole 52 is communicated with the filter hole 25, and the cleaning block 60 extends into the guide hole 52 and the filter hole 25 to clean them to avoid clogging of the guide hole 52 and the filter hole 25, thereby ensuring the filtering effect.

[0048] When the movable plate 24 moves upward, the first wedge block 65 and the second wedge block 66 move away from each other; when the movable plate 24 moves downward, the second wedge block 66 squeezes the first wedge block 65 to drive the strip block 62 to move laterally, that is, the two strip blocks 62 are close to each other and the third spring 63 is compressed; during the lateral movement of the strip block 62, the strip block 62 drives the impact block 64 to move synchronously, so that the impact block 64 hits the cleaning block 60, and the cleaning block 60 vibrates. At this time, the cleaning block 60 is located in the guide hole 52 and the filter hole 25, so as to enhance the cleaning effect of the guide hole 52 and the filter hole 25; and the vibration of the cleaning block 60 can also allow the drug powder on the surface of the cleaning block 60 to detach, thereby improving the recovery rate of the drug powder.

[0049] In this embodiment, the width of the cleaning block 60 gradually increases from top to bottom; on the one hand, it can facilitate the top of the cleaning block 60 to extend into the guide hole 52 and the filter hole 25, and on the other hand, it can enhance the cleaning effect of the guide hole 52 and the filter hole 25.
