Technical Field
[0001] This invention relates to the field of tablet detection technology, specifically a coating removal device for detecting coated tablets. Background Technology
[0002] Currently, drug content testing requires removing the outermost coating layer of the finished tablet. Finished tablets typically have sugar coatings, powder coatings, or film coatings. The presence of this coating layer can affect the test results for some drugs; therefore, for some drugs, the coating layer must be removed to expose the tablet core before testing can proceed.
[0003] Chinese Patent Publication No. CN221326073U discloses a sugar coating removal device for pharmaceutical testing, including a base frame, a bottom plate fixed in the base frame, an annular groove on the bottom plate, a dial plate in the groove, wherein the dial plate is connected to the dial shaft by a dial rod, and a feeding rack, a lower surface grinding disc, an upper surface grinding disc and a side grinding disc are installed on the outside of the annular groove, which are distributed counterclockwise at 90-degree intervals along the outside of the annular groove of the bottom plate.
[0004] The aforementioned device uses a feeding rack to feed tablets. However, in actual use, when placing tablets in the feeding rack, since a large number of tablets are placed at once and need to be fed out sequentially, if there are any tablets in the feeding rack that are upright, they will get stuck at the discharge port of the feeding rack during feeding, affecting the feeding process.
[0005] Therefore, it is necessary to provide a coating removal device for detecting coated tablets to solve the above-mentioned technical problems. Summary of the Invention
[0006] The purpose of this invention is to provide a coating removal device for detecting coated tablets, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a coating removal device for detecting coated tablets, comprising a worktable, a grinding component and a conveying component on the worktable, and a feeding rack on the top of the worktable; a receiving groove is provided at the bottom of the feeding rack, and the receiving groove is arranged in a circular array along the axis of the feeding rack; a support plate is rotatably provided at the top of the receiving groove, and an auxiliary plate is rotatably provided at the end of the support plate away from the receiving groove, and a spacer component is provided on the support plate; the auxiliary plate and the spacer component are driven to cooperate; a trigger component driven by the conveying component is provided on the worktable, and the trigger component is driven to be connected to the support plate. When the triggering component is triggered, it drives the support plate to rotate downward to open the feeding port. At the same time, the tablet is pressed down, and the auxiliary plate rotates and drives the spacer component to move to block the tablet above the feeding tablet from falling. When the support plate rotates and resets, the tablets in the feeding rack rise and fall first through the cooperation of the spacer assembly and the support plate, causing the vertical tablets to change to a horizontal position.
[0008] As a further aspect of the present invention: the spacer assembly includes a spacer plate; a groove is provided at the top center of the support plate, the spacer plate is rotatably disposed in the groove, and a transmission assembly is provided below one end of the spacer plate near the auxiliary plate, and the transmission assembly is in transmission cooperation with the spacer plate.
[0009] As a further aspect of the present invention: a meshing second toothed plate is provided below the transmission assembly, and a through groove for sliding of the second toothed plate is provided on the side wall of the support plate, the through groove being located below the groove.
[0010] As a further aspect of the present invention: the spacer plate includes an L-plate, an arc-shaped concave plate, and an arc-shaped convex plate that are fixedly connected in sequence; the L-plate is rotatably connected to the groove via a rotating shaft.
[0011] As a further aspect of the present invention: the transmission assembly includes a gear ring; a positioning shaft is rotatably disposed inside the gear ring, a coil spring is fixedly disposed between the positioning shaft and the gear ring, and the positioning shaft is driven to a spacer plate via a belt.
[0012] As a further aspect of the present invention: the auxiliary plate has a square hole on its side wall, and the end of the second toothed plate has a protrusion, which is slidably disposed in the square hole.
[0013] As a further embodiment of the present invention: a gear is fixedly provided on the end side of the support plate near the storage groove, a sliding groove is provided on the side wall of the feeding rack, the gear is disposed in the sliding groove, a first toothed plate that is slidably disposed in the sliding groove and engages with the gear transmission, a collar is slidably sleeved on the periphery of the feeding rack, the collar is fixedly connected to the first toothed plate, and the first toothed plate and the sliding groove are elastically connected.
[0014] As a further aspect of the present invention: the triggering component includes a roller; the roller is rotatably mounted on the top of the workbench, a trigger rod is fixedly mounted on the periphery of the roller, a pull rope is wound around the roller, and the end of the pull rope away from the roller slides through the side wall of the loading frame and is fixedly connected to a set of first toothed plates.
[0015] As a further aspect of the present invention: the top end of the arc-shaped convex plate is higher than the top surface of the L plate.
[0016] As a further aspect of the present invention: a tension spring is fixedly provided between the L-plate and the groove.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the cooperation of the support plate, auxiliary plate, partition plate and transmission assembly, when the partition plate rotates out of the groove during use, the arc-shaped convex plate protrudes from the L-plate, so the arc-shaped convex plate will contact the side wall of the tablet to be fed and slide, so that the arc-shaped convex plate moves to the gap between two tablets and extends into the gap, thereby supporting the medicine. This realizes that the partition plate automatically extends into and isolates the tablets above each time it is fed, ensuring that only the bottom tablet is allowed to pass through at any time, avoiding the problem of frequently adjusting the height of the feeding rack for tablets of different thicknesses. At the same time, after one feeding is completed, the trigger assembly and the conveying assembly disengage and reset, then the support plate rotates and resets, and then the partition assembly rotates and resets. Through the cooperation of the partition assembly and the support plate, the tablets in the feeding rack are made to rise first and then fall back, thereby changing the tablets that may be in a vertical position when the feeding rack is initially placed into a horizontal position during this process, realizing the smooth feeding and avoiding the tablets getting stuck at the discharge port.

Detailed Implementation
[0030] Please see Figures 1-11 In this embodiment of the invention, a coating removal device for detecting coated tablets includes a worktable 1. A support is provided at the bottom of the worktable 1 to support the worktable 1. A grinding component 2 for removing the tablet coating is provided on the worktable 1. A conveying component is provided at the center of the worktable 1. A feeding rack 3 is provided at the top of the worktable 1. The feeding rack 3 is installed on the top of the worktable 1 via a mounting plate 301. When detecting tablets, the tablets to be detected are added to the feeding rack 3. The tablets then fall from the bottom of the feeding rack 3 onto the worktable 1 and are moved to the position of the grinding component 2 under the action of the conveying component. The grinding component 2 is then activated to complete the grinding removal of the tablet coating, and subsequent detection work is then carried out.
[0031] It should be noted that both the grinding assembly 2 and the conveying assembly are existing technologies, and their detailed structures and working principles will not be elaborated here. It is worth noting that in this embodiment, three sets of grinding assemblies 2 are arranged in a circular array along the axis of the worktable 1. Two sets of grinding assemblies 2 are installed on the top of the worktable 1 near the edge, and one set is installed on the bottom edge of the worktable 1. The top of the worktable 1 is also provided with an annular groove for grinding and removing tablet coatings and for conveying the tablets. Within the annular groove, a station for grinding and removing tablet coatings is also provided at the corresponding position of each set of grinding assemblies 2. The bottom of the feeding rack 3 corresponds to the position of the annular groove. The conveying component includes a rotating shaft 4 rotatably installed at the top center of the workbench 1. The rotating shaft 4 is connected to a drive motor, which is fixedly installed on the workbench 1. Four sets of connecting rods are arranged in an annular array on the outer edge of the rotating shaft 4. The end of the connecting rod is equipped with a semi-circular plate 5 that slides and fits in contact with the annular groove. When the motor drives the rotating shaft 4 to rotate, the connecting rod drives the semi-circular plate 5 to rotate in the annular groove, thereby conveying the tablets falling from the feeding rack 3 to the bottom of the grinding component 2. Then, the grinding component 2 is started to complete the grinding and removal of the tablet coating.
[0032] Of course, the specific structure, installation position, and method of the grinding component 2 and the conveying component include, but are not limited to, the structure, installation position, and method described above.
[0033] Please see Figures 1-6 Preferably, the bottom of the feeding rack 3 is provided with a storage groove 11, and the storage groove 11 is arranged in a circular array along the axis of the feeding rack 3. A support plate 10 is rotatably provided at the top of the storage groove 11. The bottom of the feeding rack 3 is a tablet discharge port, and the support plate 10 opens and closes the discharge port. An auxiliary plate 12 is rotatably provided at the end of the support plate 10 away from the storage groove 11, and an interval component is provided on the support plate 10. The auxiliary plate 12 and the interval component are driven to cooperate. A trigger component is provided at the top of the workbench 1, and the trigger component is driven to cooperate with the support plate 10.
[0034] When the conveying component rotates and engages with the triggering component, the drive support plate 10 rotates downward and retracts into the receiving groove 11. Simultaneously, the tablet presses down on the auxiliary plate 12, causing it to rotate downward, thus completing the unloading of the tablets from the feeding rack 3. As the auxiliary plate 12 rotates downward, it also drives the spacing component to rotate downward, ensuring that only one tablet is unloaded at a time. This avoids the problem of tablets of the same type having consistent appearance and diameter but varying thicknesses due to differences in dosage during tablet detection. In such cases, existing devices require frequent adjustments to the spacing between the feeding rack 3 and the annular groove. To ensure that only a single tablet can pass through the designated spacing, a spacing component eliminates the need for operators to adjust the height between the bottom of the feeding rack 3 and the worktable 1 based on tablet thickness, allowing for single-tablet feeding. After one feeding cycle, the trigger component disengages from the conveying component and resets. Subsequently, the support plate 10 rotates and resets, followed by the spacing component rotating and resetting. Through the cooperation of the spacing component and the support plate 10, the tablets in the feeding rack 3 are allowed to rise and then fall, thus preventing tablets that might have been initially positioned vertically (such as...) from passing through the feeding rack 3. Figure 1 As shown in the figure, during this vibration process, it changes to a horizontal posture, so as to achieve smooth feeding and avoid tablets getting stuck at the discharge port.
[0035] Please see Figures 4-8Preferably, the support plate 10 has a notch at the end away from the storage groove 11, and the auxiliary plate 12 is rotatably disposed at the end of the notch near the storage groove 11. A torsion spring is provided at the rotatable connection between the auxiliary plate 12 and the support plate 10. In the initial state, the support plate 10 is in a horizontal state, that is, perpendicular to the storage groove 11. At this time, the auxiliary plate 12 is in a vertical state under the action of the torsion spring, thus forming a support for the tablets in the feeding rack 3 in conjunction with the support plate 10. When the tablet coating is removed by grinding, the conveying component rotates and cooperates with the triggering component through the semi-circular plate 5. The drive support plate 10 rotates downward and retracts into the storage groove 11. During this process, the auxiliary plate 12 gradually rotates towards the end away from the storage groove 11 under the gravity of the tablet until it retracts into the notch, and then the tablet can be unloaded. After unloading is completed, the conveying component and the triggering component are disengaged, and the triggering component resets and drives the support plate 10 to rotate and reset. During this process, the auxiliary plate 12 rotates and resets to prepare for the next unloading. At the same time, the spacing component integrates the posture of the tablets in the feeding rack 3 to avoid the tablets in a vertical posture from affecting the unloading.
[0036] Furthermore, the spacer assembly includes a spacer plate 13; a groove 15 is provided at the top center of the support plate 10, and the groove 15 is located between the auxiliary plate 12 and the storage groove 11. The spacer plate 13 is rotatably disposed in the groove 15, and the end of the spacer plate 13 near the auxiliary plate 12 is rotatably connected to the end of the groove 15 near the auxiliary plate 12 via a rotating shaft. A transmission assembly 20 is provided below the end of the spacer plate 13 near the auxiliary plate 12. The transmission assembly 20 is rotatably disposed in the side wall of the support plate 10, and the transmission assembly 20 and the spacer plate 13 are connected by a rotating shaft and a belt drive. A meshing second toothed plate 18 is provided below the transmission assembly 20. A through groove 17 for sliding of the second toothed plate 18 is provided on the side wall of the support plate 10. The through groove 17 is located below the groove 15 and passes through both ends of the auxiliary plate 12.
[0037] In use, initially, the auxiliary plate 12 is vertical, and the end of the second toothed plate 18 near the auxiliary plate 12 extends into the notch. The second toothed plate 18 meshes with the transmission assembly 20, and the spacer plate 13 is horizontal and retracted into the groove 15. When the tablet coating is removed by grinding, the cooperation of the conveying assembly and the triggering assembly causes the support plate 10 to rotate and retract into the receiving groove 11. During this process, when the auxiliary plate 12 rotates under the pressure of the tablet, the rotation of the auxiliary plate 12 causes the second toothed plate 18 to move away from the auxiliary plate 12 in the through groove 17. The movement of the second toothed plate 18 causes the transmission assembly 20 to rotate, and the rotation of the transmission assembly 20 transmits the signal through the leather... The belt and the rotating shaft work together to rotate the spacer plate 13 in the groove 15 towards the tablets, thereby isolating and blocking the tablets above the unloaded tablets through the spacer plate 13, avoiding the problem of unloading multiple tablets at once; after one unloading is completed, the trigger component and the conveying component disengage and reset, and then the support plate 10 rotates and resets. During this process, the spacer plate 13 pushes the tablets above it to move upward in the loading rack 3. When the support plate 10 resets to the horizontal state, the spacer plate 13 rotates to separate from the tablets and resets and retracts in the groove 15. At this time, the tablets fall downward, so that the tablets in the loading rack 3 that were in a vertical position are transformed into a horizontal position during this first rising and then falling motion.
[0038] Please see Figures 8-9 Preferably, the spacer 13 includes an L-plate 131, an arc-shaped concave plate 132, and an arc-shaped convex plate 133. The L-plate 131, the arc-shaped concave plate 132, and the arc-shaped convex plate 133 are fixedly connected in sequence. The L-plate 131 is rotatably connected to the groove 15 via a rotating shaft. At the same time, the rotating shaft on the L-plate 131 is driven by the transmission assembly 20 via a belt. The arc-shaped concave plate 132 is set with an arc-shaped plate structure, and the arc-shaped convex plate 133 is set with an arc-shaped protrusion structure. The top height of the arc-shaped convex plate 133 is higher than the top height of the L-plate 131. The arc-shaped convex plate 133 is made of a flexible and deformable material, and the end is rounded. In addition, the end of the arc-shaped concave plate 132 near the arc-shaped convex plate 133 is also made of a flexible and deformable material. The curvature of the arc-shaped concave plate 132 can be set according to actual needs.
[0039] When the partition plate 13 rotates out of the groove 15, the arc-shaped protrusion 133 protrudes from the L-plate 131, so the arc-shaped protrusion 133 will contact the side wall of the tablet to be fed and slide. Since the two ends of the tablet itself are curved, there will be a gap between the edges of the two tablets. This means that when the bottom tablet in the feeding rack 3 moves down, the arc-shaped protrusion 133 moves to the gap between the two tablets, and the arc-shaped protrusion 133 will extend into the gap. Then the partition plate 13 continues to rotate until it supports the medicine. By the cooperation of the arc-shaped concave plate 132 which is concave inward towards the groove 15 and the arc-shaped protrusion 133 which protrudes towards the tablet, the partition plate 13 automatically extends in and isolates the tablet above each time it is fed, ensuring that only the bottom tablet is allowed to pass through at any time. This avoids the problem of adjusting the height of the feeding rack 3 for tablets of different thicknesses in the prior art and reduces the complexity of operation.
[0040] Furthermore, the transmission assembly 20 includes a gear ring 14; a positioning shaft 22 is rotatably mounted inside the gear ring 14, and a coil spring 21 is fixedly mounted between the positioning shaft 22 and the gear ring 14. The positioning shaft 22 is driven by a belt to a rotating shaft on the spacer plate 13. When the second gear plate 18 moves, the second gear plate 18 drives the gear ring 14 to rotate. The rotation of the gear ring 14 drives the positioning shaft 22 to rotate via the coil spring 21. In turn, the rotation of the positioning shaft 22 drives the rotating shaft on the spacer plate 13 to rotate via the belt, thereby causing the spacer plate 13 to rotate. In actual use, if the spacer plate 13 rotates and comes into contact with the side wall of the tablet, the spacer plate 13 can no longer rotate. Therefore, at this time, the coil spring 21 can ensure that even if the spacer plate 13 cannot rotate, it will not affect the transmission between the second toothed plate 18 and the toothed ring 14. When the spacer plate 13 cannot rotate, the coil spring 21 will be deformed by force, thereby applying a continuous rotational force to the spacer plate 13. When the arc-shaped protrusion 133 on the spacer plate 13 is in the gap between two tablets, the arc-shaped protrusion 133 extends into the gap, and under the action of the arc-shaped concave plate 132, the spacer plate 13 continues to rotate, realizing the feeding of one tablet at a time, that is, isolating the tablets above the feeding tablets. The rotation of the arc-shaped concave plate 132 will also promote the feeding speed of the tablets at the bottom of the feeding rack 3.
[0041] Please see Figure 7 , Figure 11 A tension spring 23 is fixedly installed between the L plate 131 and the groove 15. The tension spring 23 provides power for the spacer plate 13 to rotate and reset.
[0042] A square hole 19 is provided on the side wall of the auxiliary plate 12 near the second toothed plate 18. The second toothed plate 18 has protrusions on both sides of the end near the auxiliary plate 12. The protrusions are slidably disposed in the square hole 19. When the support plate 10 is horizontal and the auxiliary plate 12 is vertical, the second toothed plate 18 extends into the notch to the maximum extent under the action of the square hole 19. At this time, the partition plate 13 retracts into the groove 15 under the cooperation of the transmission assembly 20 and the second toothed plate 18. When the auxiliary plate 12 rotates to retract into the notch, the auxiliary plate 12 will push the second toothed plate 18 to move towards the transmission assembly 20 through the square hole 19, thereby driving the transmission assembly 20 to rotate.
[0043] It should be noted that when the auxiliary plate 12 rotates and retracts into the notch, the height of the square hole 19 corresponds to the height of the second toothed plate 18, and the length of the square hole 19 also satisfies the distance that the second toothed plate 18 moves when the auxiliary plate 12 rotates.
[0044] Please see Figures 1-6 Preferably, a gear 16 is fixedly installed on one side of the support plate 10 near the end of the receiving groove 11, a slide groove 8 is provided on the side wall of the feeding rack 3, the gear 16 is installed in the slide groove 8, a first toothed plate 9 that is slidably installed in the slide groove 8 and drives the gear 16, a collar 7 is slidably sleeved on the periphery of the feeding rack 3, the collar 7 is fixedly connected to the first toothed plate 9, and the bottom of the first toothed plate 9 and the bottom of the slide groove 8 are elastically connected by a spring.
[0045] Please see Figures 1-11 Preferably, the triggering component includes a roller 6; the roller 6 is rotatably mounted on the top of the workbench 1, and is mounted on the side of the loading rack 3 corresponding to the semicircular plate 5 that rotates closer to the loading rack 3. A torsion spring is provided at the rotatable connection between the roller 6 and the workbench 1 to facilitate the rotational reset of the roller 6. A trigger rod 602 is fixedly mounted on the periphery of the roller 6, and the trigger rod 602 extends above the annular groove. The height of the semicircular plate 5 is slightly higher than the height of the annular groove. When the conveying component rotates, the semicircular plate 5 and the trigger rod 602 will slide together, thereby driving the roller 6 to rotate through the trigger rod 602. A pull rope 601 is wound around the roller 6, and the end of the pull rope 601 away from the roller 6 slides through the side wall of the loading rack 3 and is fixedly connected to a set of first toothed plates 9.
[0046] In practical use, initially when there are no tablets in the feeding rack 3, such as Figures 2-7 , Figure 11As shown in the first figure, the end of the trigger rod 602 faces away from the loading rack 3. The support plate 10 is horizontal, the auxiliary plate 12 is vertical, the spacer plate 13 is retracted into the groove 15, and the first toothed plate 9 meshes with the gear 16. When it is necessary to remove the coating of the test tablet, the tablet is added into the loading rack 3. At this time, the horizontal support plate 10 and the auxiliary plate 12 form a support for the tablet. Then the conveying assembly is started, and the semicircular plate 5 in the conveying assembly rotates in the annular groove. When a set of semicircular plates 5 rotates to the trigger rod 602, it will engage with the trigger rod 602 and push the trigger rod 602 to rotate towards the loading rack 3. The rotation of the trigger rod 602 will cause the tablet to rotate. The rotating roller 6 rotates until the trigger rod 602 rotates and separates from the semi-circular plate 5. Then, the trigger rod 602 elastically rotates and resets under the action of the torsion spring of the roller 6. During this process, the rotation of the roller 6 unwinds the pull rope 601, causing the first toothed plate 9 to move upwards under the corresponding elastic action. The upward movement of the first toothed plate 9 causes the gear 16 to rotate, which in turn drives the support plate 10 to rotate downwards. During the rotation of the support plate 10, the tablet gradually moves downwards, causing the auxiliary plate 12 to rotate downwards. The rotation of the auxiliary plate 12 then pushes the second toothed plate 18 to move, which in turn causes the spacer plate 13 to rotate towards the tablet via the transmission assembly 20, thus realizing the feeding of one tablet at a time (see [reference]). Figure 11 (As shown in the first to fourth attached figures), after the tablets fall into the annular groove from the bottom of the feeding rack 3, the conveying assembly transports them to the corresponding grinding station for coating removal. This process repeats. After the unloading is completed, when the winding roller 6 rotates to its reset position, it forms a winding action on the pull rope 601, causing the first toothed plate 9 to move downwards. The downward movement of the first toothed plate 9 causes the gear 16 to rotate, which in turn drives the support plate 10 to rotate upwards to its reset position. During this process, the spacer plate 13 supports the tablets upwards, that is, moves upwards within the feeding rack 3. When the support plate 10 rotates to its reset position and stops rotating, the spacer plate 13... Since the length of plate 3 is greater than the length of plate 12, when plate 10 rotates and resets, plate 13 will rotate and reset under the rotational inertia of plate 10 and the corresponding tension spring 23, as well as the corresponding torsion spring on plate 12. That is, plate 13 will rotate into groove 15 to separate from the tablet, and plate 12 will rotate towards the medicine to a state that is relatively perpendicular to plate 10. During this process, the tablet will change from rising motion to falling motion, thereby allowing the tablet in the feed rack 3 to be aligned and then fall onto the vertical plate 12, ready for the next feeding.
