Description

Technical Field

[0001] This invention relates to the field of grinding technology, and more specifically to a pediatric drug grinder. Background Technology

[0002] Pediatrics is a comprehensive medical science that studies the physical and mental development, health care, and disease prevention of children. Children often find it difficult to take medications due to their bitter taste. The traditional solution is to grind the medications into powder and mix them with food or drinks. However, this traditional method is labor-intensive and inefficient.

[0003] To address the problems of traditional grinding methods, numerous grinding devices have emerged on the market. For example, Chinese Patent CN214916551U discloses a high-efficiency grinding wheel device for pediatric medications. This device includes a grinding box with a collection box on its front. A drive motor is fixedly installed at the bottom inside the grinding box. Guide rails located above the drive motor are fixedly connected to both sides inside the grinding box. A grinding chamber is located inside the grinding box, above the guide rails. A synchronous pulley is fixedly installed at the output end of the drive motor. A rotating shaft is concentrically connected to the grinding chamber. A screen is fixedly installed at the bottom of the grinding chamber. A second synchronous pulley is fixedly installed at one end of the rotating shaft. A connecting disc located inside the grinding chamber is fixedly installed on the rotating shaft. The second synchronous pulley is connected to the first synchronous pulley via a synchronous belt. A sliding block is slidably connected to the guide rails. This grinding device uses a mechanical structure to replace manual grinding of medications, effectively reducing labor intensity and improving work efficiency.

[0004] The above-mentioned grinding device has the following problems during actual operation: After the drug is ground, it becomes powder. The powder passes through the screen and is collected in the collection box. The powder can be obtained by removing the collection box. As the usage time increases, more and more powder accumulates on the screen, which will cause blockage. However, the screen is located inside the grinding box, making it inconvenient to clean. This results in less or no output. Summary of the Invention

[0005] The present invention aims to provide a pediatric drug grinder to solve the problem of material output being affected by the internal screen blockage of existing grinding devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pediatric drug grinder, comprising a cylindrical container with an opening at the top and a discharge port at the bottom; a support member connected inside the container, a side block on the support member, and bottom blocks on both sides of the bottom of the side block; a wall groove vertically provided on the side wall of the bottom block, with a wall block slidably connected in the wall groove; a cylinder provided between the two wall blocks, with a feed inlet on the cylinder, and a sealing block detachably connected to the feed inlet; a grinding mechanism provided inside the cylinder, with a plurality of sieve holes provided along the length of the cylinder on the arc-shaped surface; a fixing block provided between the two bottom blocks, with a plurality of cleaning blocks provided along the length of the fixing block, the cleaning blocks extending into the sieve holes, and the cleaning blocks being able to move vertically within the sieve holes; and an adjustment mechanism for simultaneously driving the two wall blocks to reciprocate vertically.

[0007] The principle and advantages of this scheme are: 1. In this method, the drug is placed into the cylinder through the inlet and sealed with a sealing block. The drug in the cylinder is ground by a grinding mechanism to obtain powder. The powder falls through the sieve holes to the bottom of the container and is then discharged from the outlet. The adjusting mechanism can simultaneously drive two wall blocks to move vertically back and forth. The two wall blocks drive the cylinder to move vertically back and forth, so that the cleaning block moves relatively vertically in the sieve holes. That is, the cleaning block continuously enters and exits the sieve holes, which ensures that the powder is discharged from the sieve holes and avoids sieve blockage.

[0008] 2. During the vertical reciprocating motion of the cylinder in this scheme, the distance between the drug inside the cylinder and the grinding roller decreases intermittently, thereby promoting the grinding process of the drug.

[0009] Furthermore, the grinding mechanism includes a grinding roller and a power unit for driving the grinding roller to rotate, and the grinding roller can rotate inside the cylinder.

[0010] With the above setup, the grinding roller is driven by the power unit to rotate, thereby achieving the grinding process of the drug.

[0011] Furthermore, the support is a rotating shaft, which is rotatably connected to the bottom of the container. The inner wall of the container is provided with an annular groove. The end of the side block away from the rotating shaft is slidably connected to the annular groove. It also includes a drive mechanism for driving the rotating shaft to rotate. The power unit includes a shaft and an annular rack fixed to the bottom of the container. The shaft is rotatably connected to the bottom block. The grinding roller is coaxially connected to the shaft. A gear is coaxially connected to the shaft, and the gear meshes with the annular rack.

[0012] With the above configuration, the drive mechanism drives the rotating shaft to rotate, the rotating shaft drives the side block to rotate along the path of the annular groove, the side block drives the bottom block and shaft to move synchronously, the gear meshes with the annular rack to drive the shaft to rotate, and the shaft drives the grinding roller to rotate.

[0013] Furthermore, the shaft includes a round shaft and side shafts coaxially connected to both ends of the round shaft. The grinding roller is coaxially connected to the round shaft, the side shaft is rotatably connected to the bottom block, and the gear is coaxially connected to the side shaft away from the rotating shaft. The adjustment mechanism includes adjustment parts located on both sides of the cylinder. The adjustment parts include a chamber opened inside the bottom block and an adjustment unit located inside the chamber. The wall groove communicates with the chamber, the side shaft extends into the chamber, and the adjustment unit can drive the wall block to move vertically back and forth as the side shaft rotates.

[0014] With the above configuration, during the rotation of the side block, the side block drives the bottom block and shaft to move synchronously. That is, the bottom block drives the round shaft and the two side shafts to move synchronously. The gear meshes with the ring rack to drive the round shaft and side shafts to rotate, and the round shaft drives the grinding roller to rotate.

[0015] Furthermore, the side shaft is a worm gear; the adjustment part includes an adjustment shaft that is rotatably connected to the chamber, a worm wheel and a cylindrical cam that are coaxially connected to the adjustment shaft, the worm wheel meshing with the worm gear, and the cylindrical cam having a curved groove, with the end of the wall block away from the cylinder being slidably connected to the curved groove.

[0016] With the above configuration, during the rotation of the side block, the side block drives the bottom block and shaft to move synchronously. That is, the bottom block drives the round shaft and two worm gears to move synchronously. The gear meshes with the ring rack to drive the round shaft and worm gears to rotate, and the round shaft drives the grinding roller to rotate.

[0017] During the rotation of the worm, the worm meshes with the worm wheel, driving the adjusting shaft to rotate. The adjusting shaft drives the cylindrical cam to rotate, and the cylindrical cam drives the cylinder to rotate vertically and reciprocally through the curved groove and the wall block. This causes the gap between the drug inside the cylinder and the grinding roller to decrease intermittently, thereby promoting the grinding process of the drug.

[0018] Furthermore, the two ends of the cylinder are in frictional contact with the two bottom blocks respectively, and the two ends of the cylinder are connected to the cavities of the two bottom blocks respectively; inside the cylinder, on both sides of the grinding roller, there are slidably connected discs, and the discs are provided with vertical holes. The diameter of the circular shaft is smaller than the width of the vertical hole, and the circular shaft can rotate and move vertically within the vertical hole; a top block is provided between the two discs, and the top block is located above the grinding roller; it also includes a linkage mechanism that drives the two discs to reciprocate laterally as the two adjusting shafts rotate.

[0019] With the above setup, during the rotation of the two adjusting shafts, the linkage mechanism can drive the two discs to reciprocate laterally. The drug is located between the two discs, and the two discs can facilitate the replacement of the drug position, promote comprehensive and uniform grinding of the drug, and achieve better grinding effect. Since the diameter of the shaft is smaller than the width of the vertical hole on the disc, the disc can reciprocate laterally relative to the shaft through the vertical hole, and the shaft can rotate within the vertical hole, so that the movement of the shaft and the disc do not affect each other.

[0020] Furthermore, the linkage mechanism includes two cam bodies, which are coaxially connected to the adjustment shaft. The convex directions of the two cam bodies are aligned, and the cam bodies extend into the cylinder and abut against the disc.

[0021] With the above settings, during the rotation of the two adjusting shafts, the adjusting shafts drive the cam bodies to rotate, that is, the two cam bodies move synchronously; since the convex directions of the two cam bodies are in the same direction, and a top block is fixed between the two discs, the two cam bodies can drive the two discs to move synchronously and laterally reciprocatingly by acting on the two discs.

[0022] Furthermore, a scraper is provided at the bottom of the fixing block, with the end of the scraper away from the fixing block abutting against the bottom of the container.

[0023] With the above setup, during the rotation of the two bottom blocks inside the container, the two bottom blocks drive the fixed block to move synchronously, and the fixed block drives the scraper to move synchronously. The scraper then drives the powdered medicine at the bottom of the container to the discharge port for discharge.

[0024] Furthermore, the cylinder is equipped with a curved block and panels on both sides of the curved block. Both sides of the curved block are provided with side grooves, and side blocks are slidably connected in the side grooves. The panel is located above the grinding roller, and a strip groove is provided on the panel horizontally. A movable block is slidably connected in the strip groove, and the side block is fixedly connected to the movable block. A bristle layer is provided at the bottom of the movable block, and the free end of the bristle layer abuts against the grinding roller. Auxiliary blocks are slidably connected vertically on both sides of the curved block on the cylinder, and the two ends of the auxiliary blocks are fixedly connected to the side block and the panel, respectively.

[0025] With the above settings, the brush layer can clean the grinding roller during its rotation. During the vertical reciprocating motion of the cylinder, the panel and auxiliary block move vertically relative to the cylinder, causing the movable block to move vertically relative to the curved block. The movable block moves laterally along the path of the side groove and the side block along the strip groove. That is, the brush layer can move along the axial direction of the circular shaft and act on the grinding roller. In this way, the brush layer can drive the powdered medicine on the grinding roller to fall off the end of the grinding roller, thereby improving the recovery rate and utilization rate of the powdered medicine.

The cleaning blocks 27 extend into the sieve holes 25 and can move vertically in the sieve holes 25, that is, the cleaning blocks 27 can enter and exit the sieve holes 25.

[0030] The cleaning block 27 is conical, and its width gradually increases from top to bottom; the sieve hole 25 is cylindrical, and its diameter is smaller than the maximum width of the cleaning block 27. A scraper 28 is fixedly connected to the bottom of the fixing block 26, and the end of the scraper 28 away from the fixing block 26 abuts against the bottom of the container 10.

[0031] The grinding mechanism includes a grinding roller 30 and a power unit for driving the grinding roller 30 to rotate. The grinding roller 30 can rotate inside the cylinder 23. The power unit includes a shaft and an annular rack 31 fixed to the bottom of the container 10. The shaft is rotatably connected to the bottom block 20. The grinding roller 30 is coaxially connected to the shaft. A gear 32 is coaxially connected to the shaft, and the gear 32 meshes with the annular rack 31. The shaft includes a round shaft 33 and side shafts coaxially connected to both ends of the round shaft 33. The grinding roller 30 is coaxially connected to the round shaft 33, the side shafts are rotatably connected to the bottom block 20, and the gear 32 is coaxially connected to the side shaft away from the rotating shaft 14.

[0032] It also includes an adjustment mechanism for simultaneously driving the two wall blocks 22 to reciprocate vertically. The adjustment mechanism includes adjustment sections located on both sides of the cylinder 23. Each adjustment section includes a chamber opened inside the bottom block 20 and an adjustment unit located inside the chamber. The wall groove 21 communicates with the chamber, and a side shaft extends into the chamber. The adjustment unit can drive the wall block 22 to reciprocate vertically by rotating with the side shaft. The side shaft is a worm gear 34. The adjustment unit includes an adjustment shaft 35 rotatably connected to the chamber, a worm wheel 36 coaxially connected to the adjustment shaft 35, and a cylindrical cam 37. The adjustment shaft 35 is vertically arranged, the worm wheel 36 meshes with the worm gear 34, and the cylindrical cam 37 has a curved groove. The end of the wall block 22 away from the cylinder 23 is slidably connected to the curved groove.

[0033] The two ends of the cylinder 23 are in frictional contact with the two bottom blocks 20 respectively, and the two ends of the cylinder 23 are connected to the cavities of the two bottom blocks 20 respectively; inside the cylinder 23, on both sides of the grinding roller 30, there are slidably connected discs 40, and the discs 40 have vertical holes 41. The diameter of the shaft 33 is smaller than the width of the vertical hole 41, and the shaft 33 can rotate and move vertically within the vertical hole 41; a top block 42 is fixed between the two discs 40, and the top block 42 is located above the grinding roller 30.

[0034] It also includes a linkage mechanism that drives two discs 40 to reciprocate laterally as the two adjusting shafts 35 rotate, and the two discs 40 move in the same direction. The linkage mechanism includes two cam bodies 43, which are coaxially connected to the adjusting shafts 35. The convex directions of the two cam bodies 43 are the same, and the cam bodies 43 extend into the cylinder 23 and abut against the discs 40.

[0035] The specific implementation process is as follows: In use, the medicine is placed into the cylinder 23 through the feed port, so that the medicine is located below the grinding roller 30; the sealing block 24 is connected to the feed port to seal the feed port.

[0036] When the motor is started, the output shaft of the motor drives the rotating shaft 14 to rotate, and the rotating shaft 14 drives the side block 15 to rotate along the path of the annular groove 13. During the rotation of the side block 15, the side block 15 drives the two bottom blocks 20 to move synchronously. The bottom blocks 20 drive the worm gear 34 and the gear 32 to move synchronously. The gear 32 meshes with the annular rack 31 and drives the gear 32 to rotate. The gear 32 drives the worm gear 34 and the round shaft 33 to rotate. The round shaft 33 drives the grinding roller 30 to rotate, thereby realizing the grinding of the drug to obtain powdered drug. The powdered drug falls into the bottom of the container 10 through the sieve hole 25. During the rotation of the two bottom blocks 20 in the container 10, the two bottom blocks 20 drive the fixed block 26 to move synchronously. The fixed block 26 drives the scraper 28 to move synchronously. The scraper 28 drives the powdered drug at the bottom of the container 10 to the discharge port 12 for discharge.

[0037] During the rotation of the worm 34, the worm 34 meshes with the worm wheel 36 to drive the adjustment shaft 35 to rotate. The adjustment shaft 35 drives the cylindrical cam 37 to rotate. The cylindrical cam 37 drives the cylinder 23 to rotate vertically and reciprocally through the curved groove and the wall block 22, so that the distance between the drug in the cylinder 23 and the grinding roller 30 is reduced intermittently, thereby promoting the grinding process of the drug.

[0038] During the vertical reciprocating motion of the cylinder 23, the cleaning block 27 moves relatively vertically within the sieve hole 25, meaning that the cleaning block 27 continuously enters and exits the sieve hole 25. This ensures that the powdered medicine is discharged from the sieve hole 25 while preventing the sieve hole 25 from becoming clogged.

[0039] During the rotation of the two adjusting shafts 35, the adjusting shafts 35 drive the cam bodies 43 to rotate, that is, the two cam bodies 43 move synchronously. Since the convex directions of the two cam bodies 43 are consistent, and the top block 42 is fixed between the two discs 40, the two cam bodies 43 can drive the two discs 40 to move synchronously and laterally reciprocatingly through the action of the two discs 40. This can promote the replacement of the drug position in the cylinder 23, promote the comprehensive and uniform grinding of the drug, and improve the grinding effect. Since the diameter of the shaft 33 is smaller than the width of the vertical hole 41 on the disc 40, the disc 40 can move laterally reciprocatingly relative to the shaft 33 through the vertical hole 41, and the shaft 33 can rotate within the vertical hole 41, so that the movements of the shaft 33 and the disc 40 do not affect each other.

[0040] In this embodiment, a curved block 50 and two panels 51 are fixedly connected inside the cylinder 23. The two panels 51 are located on both sides of the curved block 50. Side grooves 501 are opened on both sides of the curved block 50, and side blocks 52 are slidably connected in the side grooves 501. The panels 51 are located above the grinding roller 30. A strip groove 53 is opened horizontally on the panels 51. A movable block 54 is slidably connected in the strip groove 53. The side blocks 52 are fixedly connected to the movable block 54. A bristle layer 55 is fixedly connected to the bottom of the movable block 54, and the free end of the bristle layer 55 abuts against the grinding roller 30. Auxiliary blocks 56 are vertically slidably connected on both sides of the curved block 50 on the cylinder 23. The two ends of the auxiliary blocks 56 are fixedly connected to the side block 15 and the panel 51, respectively.

[0041] During the rotation of the grinding roller 30, the brush layer 55 can clean the grinding roller 30. During the vertical reciprocating motion of the cylinder 23, the panel 51 and the auxiliary block 56 move vertically relative to the cylinder 23, causing the movable block 54 to move vertically relative to the curved block 50. The movable block 54 moves laterally along the path of the strip groove 53 through the side groove 501 and the side block 52. That is, the brush layer 55 can move along the axial direction of the circular shaft 33 and act on the grinding roller 30. In this way, the brush layer 55 can drive the powdered medicine on the grinding roller 30 to fall from the end of the grinding roller 30, thereby improving the recovery rate and utilization rate of the powdered medicine.
