Description

Technical Field

[0001] This invention relates to the field of drug dispensing mechanisms, specifically to an automatic drug dispensing mechanism and a potassium persulfate disinfection device. Background Technology

[0002] Automatic dosing systems are used in the treatment of feedwater, boiler water, circulating water, and wastewater in power plants. They can also be used in industries such as petroleum, chemical, environmental protection, and water supply systems. In ventilation engineering, high concentrations of chemical scale such as calcium carbonate and magnesium carbonate, along with household sludge, can deposit in the high-temperature condenser, causing a significant decrease in the cooling capacity of the main unit. This necessitates the use of automatic dosing systems to treat the water. Potassium persulfate is a strong oxidizing agent capable of oxidizing many organic and inorganic substances, and is commonly used in chemical analysis, organic synthesis, and environmental remediation.

[0003] Traditional disinfection equipment involves placing disinfectant in the inner cavity of the disinfection tank before operation. Wastewater is then pumped into the tank, allowing the disinfectant to react with the wastewater. Due to varying levels of harmful substances in the wastewater, additional disinfectant is required during the disinfection process. This requires manual opening of the tank and placement of the disinfectant through a specific device. Furthermore, before each subsequent disinfection cycle, manual opening of the tank and addition of disinfectant are necessary. Since some disinfectants are irritating and toxic, manual addition can easily pollute the environment and cause harm to human health.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic dosing mechanism and a single potassium persulfate disinfection device. Through the configuration of a transmission assembly, the operation of the transport roller and the push assembly is controlled sequentially. When the transport roller rotates, one of the drug chambers adds disinfectant into the disinfection tank, while the other chamber moves directly below the storage cylinder to replenish the disinfectant. This effectively solves the problem that traditional disinfection devices, when disinfecting wastewater, require manual replenishment when disinfectant is insufficient during purification or when additional disinfectant is needed after purification. Since disinfectants are inherently toxic, this can easily cause environmental pollution and poisoning of personnel.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

The drive source drives the transmission assembly to run, and the transmission assembly drives the transport roller to rotate so that one of the medicine compartment openings is aligned with the bottom of the medicine storage cylinder. At the same time, the transmission assembly drives the push assembly to run, so that the two partitions rotate in opposite directions, thereby allowing the medicine in the medicine storage cylinder to enter the medicine compartment. Similarly, when the transport roller continues to rotate, the transmission assembly drives the push assembly to run, so that the two partitions move towards each other, sealing the top of the conveying cylinder.

[0015] Preferably, the inner wall of the conveying cylinder is provided with a circular groove, and a circular block is fitted inside the cavity of the circular groove.

[0018] The potassium persulfate disinfection equipment uses an automatic dosing mechanism for replenishing the disinfectant.

[0019] Compared with the prior art, the present invention provides an automatic drug replenishment mechanism and a potassium persulfate disinfection device, which have the following beneficial effects:

[0020] 1. This invention, through the configuration of a transmission component, sequentially controls the operation of the transport roller and the push component. When the transport roller rotates, one medicine chamber adds medicine into the disinfection tank cavity, while the other medicine chamber rotates to directly below the storage cylinder. The push component causes the movable ends of two partitions to move in opposite directions, thus adding medicine to the medicine chamber. When the disinfection tank cavity is full of medicine, the transport roller continues to rotate, causing the empty medicine chamber to rotate towards the connection between the storage cylinder and the conveyor cylinder, and the full medicine chamber to rotate directly below the conveyor cylinder, thus allowing for the next round of medicine replenishment. This solves the problem that traditional disinfection devices, when disinfecting wastewater, require manual replenishment when there is insufficient disinfectant during purification or when more disinfectant is needed after purification. Since disinfectants are toxic, this can easily cause environmental pollution and poisoning of personnel.

[0021] 2. This invention, through the sleeve connection between the locking block and the slot, and the arrangement of the locking block with an arc surface on one side and a flat surface on the other, and the sleeve connection between the movable rod and the slot, allows the bidirectional screw to rotate and drive the two moving plates to move when the movable rod is fixed to the transport roller, thereby adjusting the volume of the medicine container. When the movable rod moves outward and is no longer fixed to the transport roller, the arrangement of the locking block's flat surface and the inner wall of the slot ensures that the transport roller and the bidirectional screw rotate synchronously. This prevents the bidirectional screw from causing the moving plates to change position during drug transport, thus avoiding the problem of changes in the volume of the medicine container during drug transport.

[0022] 3. This invention utilizes the meshing connection between the rack and the outer gear ring of the rotating rod to cause the grid plate to vibrate during the upward or downward movement of the push rod. This accelerates the speed at which the medicine falls downward through the mesh holes of the grid plate. At the same time, the grid plate design prevents a large amount of medicine from being poured directly into the inner cavity of the medicine tank during drug addition, thus avoiding the problem of excessive drug accumulation at the connection between the storage cylinder and the delivery cylinder, which would make it difficult for the sealing plate to seal the opening of the medicine tank.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes an automatic drug replenishment mechanism and a potassium persulfate disinfection device.

[0036] Please see Figure 1-4 The automatic drug replenishment mechanism and potassium persulfate disinfection equipment include a disinfection device 1 and a drug replenishment device 2. The disinfection device 1 includes a disinfection tank 11, and the drug replenishment device 2 includes a drug storage cylinder 21 and a conveying cylinder 22 fixedly installed at the bottom of the drug storage cylinder 21. The conveying cylinder 22 is connected to the disinfection tank 11, and the inner cavity of the conveying cylinder 22 is provided with a transport device 3, an opening and closing device 4 and a driving device 5.

[0037] The transport device 3 includes a transport roller 31, and medicine bins 32 are provided on both sides of the outer periphery of the transport roller 31;

[0038] The opening and closing device 4 includes a mesh plate 41 and two partitions 42. The mesh plate 41 is hinged at the connection between the medicine storage cylinder 21 and the conveying cylinder 22. The two partitions 42 are located on both sides of the bottom of the mesh plate 41. One end of the partition 42 is hinged to the inner wall of the medicine storage cylinder 21. The other end of the two partitions 42 is provided with a pushing component 6 so that the other ends of the two partitions 42 can contact each other.

[0039] The driving device 5 includes a driving source 50 and a transmission assembly 51. One end of the transmission assembly 51 is powered by the conveying roller 31, and the other end is powered by the pushing assembly 6. The driving source 50 drives the transmission assembly 51 to run, and the transmission assembly 51 drives the conveying roller 31 to rotate so that the opening of one of the medicine chambers 32 is directly opposite the bottom of the medicine storage cylinder 21. At the same time, the transmission assembly 51 drives the pushing assembly 6 to run, so that the two partitions 42 rotate in opposite directions, thereby allowing the medicine in the inner cavity of the medicine storage cylinder 21 to enter the inner cavity of the medicine chamber 32. Similarly, when the conveying roller 31 continues to rotate, the transmission assembly 51 drives the pushing assembly 6 to run, so that the two partitions 42 move towards each other, sealing the top of the conveying cylinder 22.

[0040] Specifically, when it is necessary to add medicine into the inner cavity of the disinfection tank 11, the drive source 50 drives the transmission component 51 to operate, and the transmission component 51 drives the transport roller 31 and the push component 6 to operate simultaneously.

[0041] The transport roller 31 rotates, causing one of the medicine bins 32 to rotate upwards, so that the opening of the medicine bin 32 is directly below the medicine storage cylinder 21;

[0042] Simultaneously, the drive component 6 operates, causing the movable ends of the two partitions 42 to rotate in opposite directions, thereby opening the space between the two partitions 42 and allowing the medicine in the inner cavity of the medicine storage cylinder 21 to fall into the inner cavity of the medicine chamber 32. At the same time, the transport roller 31 continues to rotate, causing the medicine chamber 32 to slowly move away from the position directly below the medicine storage cylinder 21. At this time, the drive component 6 causes the movable ends of the two partitions 42 to rotate in opposite directions, thereby sealing the space below the mesh plate 41, thus preventing the medicine in the inner cavity of the medicine storage cylinder 21 from continuously falling onto the transport roller 31. When the open end of the medicine chamber 32, which is full of medicine on the transport roller 31, is directly below the conveyor cylinder 22, the medicine falls into the inner cavity of the disinfection tank 11, filling the inner cavity of the other medicine chamber 32 with medicine, ready for the next replenishment of medicine.

[0043] By controlling the operation of the conveyor roller 31 and the pusher assembly 6 in sequence through the transmission assembly 51, one of the medicine bins 32 adds medicine into the inner cavity of the disinfection tank 11 while the other medicine bin 32 moves to the bottom of the storage cylinder 21. The pusher assembly 6 causes the movable ends of the two partitions 42 to move in opposite directions, thus adding medicine to the medicine bins 32. When the inner cavity of the disinfection tank 11 is full of medicine, the conveyor roller 31 continues to rotate, causing the empty medicine bin 32 to rotate towards the connection between the storage cylinder 21 and the conveyor cylinder 22, and causing the full medicine bin 32 to rotate directly below the conveyor cylinder 22, thus allowing for the next step of medicine replenishment. This effectively solves the problem that in traditional disinfection devices 1, when there is insufficient disinfectant during the purification process or when medicine needs to be added again after purification, medicine is replenished manually. Since the disinfectant itself is toxic, it can easily cause environmental pollution and poisoning of personnel.

[0044] Further, see Figure 4 For the above-mentioned transport device 3, the transport device 3 also includes a sealing assembly 33, which includes a sealing plate 331. A guide rail groove 332 is provided on the inner wall of the medicine container 32. The sealing plate 331 is slidably disposed in the inner cavity of the guide rail groove 332. A guide rail rod is fixedly disposed in the inner cavity of the guide rail groove 332. The sealing plate 331 is slidably disposed on the outer periphery of the guide rail rod. A first spring 333 is provided at the end of the sealing plate 331 away from the medicine container 32. The first spring 333 is sleeved on the outer periphery of the guide rail rod. A fixing block 334 is fixedly installed at the edge of the outer side of the sealing plate 331 away from the first spring 333. One side of the fixing block 334 is provided with an arc surface. The other side of the fixing block 334 is provided with a flat surface. A baffle 335 is hinged to the top of one side and the bottom of the other side of the inner cavity of the conveying cylinder 22. A torsion spring 336 is installed at the hinge of the baffle 335 and the conveying cylinder 22. The end of the baffle 335 away from the torsion spring 336 is provided with a curved shape.

[0045] Specifically, when the transport roller 31 rotates with the transmission device, and one of the medicine bins 32 rotates directly above the medicine storage cylinder 21, the arc surface of the fixing block 334 above the sealing plate 331 contacts the curved surface of the baffle 335. Due to the slidable arrangement of the sealing plate 331 within the guide groove 332, the sealing plate 331 is retracted into the guide groove 332 during the rotation of the transport roller 31, and the first spring 333 is compressed. When the opening end of the medicine bin 32 above the medicine storage cylinder 21 is directly above the medicine storage cylinder 21, the medicine storage cylinder 21 adds medicine to the medicine bin 32. The transport roller 31 continues to rotate, causing the fixing block 334 to press against the baffle 335. The arc surface of the fixing block 334 further compresses the pressure. The movable end of the baffle 335 rotates upward and compresses the torsion spring 336. When the fixing block 334 disengages from the curved surface of the baffle 335, the first spring 333 regains its elasticity and pushes the sealing plate 331 outward, thereby sealing the opening of the medicine chamber 32 and reducing the spillage of medicine in the inner cavity of the medicine chamber 32. At this time, the torsion spring 336 regains its elasticity and causes the baffle 335 to return to its original position. Meanwhile, as one medicine chamber 32 rotates directly upward toward the medicine storage cylinder 21, the other medicine chamber 32 rotates directly downward toward the conveying cylinder 22. At this time, the fixing block 334 on the sealing plate 331 contacts the baffle 335 below the inner wall of the conveying cylinder 22, thereby opening the medicine chamber 32 and replenishing the inner cavity of the disinfection tank 11 with medicine.

[0046] Further, see Figure 9-10 For the aforementioned pushing assembly 6, the pushing assembly 6 includes a pushing rod 61. A rectangular groove 62 is provided on the inner wall of the conveying cylinder 22. The pushing rod 61 is slidably disposed in the inner cavity of the rectangular groove 62. Guide rods are fixedly installed on both sides of the inner cavity of the rectangular groove 62. The pushing rod 61 is slidably disposed on the outer periphery of the guide rods. A second spring 63 is provided at the top of the pushing rod 61. The second spring 63 is sleeved on the outer periphery of the guide rods. A sliding groove 64 is provided on the side of the guide rod near the partition 42. A connecting shaft 65 is slidably disposed on both sides of the inner cavity of the sliding groove 64. The end of the connecting shaft 65 away from the guide rod is rotatably connected to one end of the partition 42 through a bearing.

[0047] Specifically, during the operation of the transmission device and the upward movement of the push rod 61, the second spring 63 is compressed and in a compressed state. Through the movable hinge between the connecting shaft 65 and the two partitions 42, and the movable setting of the connecting shaft 65 in the inner cavity of the sliding groove 64, when the push rod 61 moves upward, it drives the movable ends of the two partitions 42 to move towards each other, thereby closing the top of the conveying cylinder 22. The transmission device no longer provides thrust to the push device. At this time, the second spring 63 resets and drives the push plate to move downward, causing the two partitions 42 to move relative to each other, thereby opening the top of the conveying cylinder 22 and adding medicine to the medicine chamber 32.

[0048] Further, see Figure 9-10For the aforementioned perforated plate 41, a vibration component 7 is provided at the bottom of the perforated plate 41. The vibration component 7 includes a rack 71, which is fixedly installed on the top of the push rod 61. The inner cavity of the conveying cylinder 22 is provided with an inner groove, which is connected to the rectangular groove 62. The rack 71 is slidably disposed in the inner cavity of the inner groove. The inner wall of the conveying cylinder 22 is rotatably connected to a rotating rod 72 through a bearing. The rotating rod 72 is located at the bottom of the movable end of the perforated plate 41. A toothed ring 73 is fixedly installed on the outer periphery of the rotating rod 72. The rotating rod 72 passes through the inner groove and the toothed ring 73 is disposed inside the inner groove. The rack 71 meshes with the toothed ring 73. One end of the rotating rod 72 extends into the inner cavity of the conveying cylinder 22 and multiple protrusions 74 are fixedly installed on its outer periphery.

[0049] Specifically, when the transmission device drives the push plate to move upward, the rack 71 moves upward and enters the inner groove to contact the gear ring 73. Through the meshing connection between the rack 71 and the gear ring 73, the rotating rod 72 is driven to rotate, thereby driving multiple protrusions 74 to rotate around the rotating rod 72 as the axis. During the rotation, one of the protrusions 74 rotates upward and provides a pushing force to lift the movable end of the grid plate. When the protrusion 74 is separated from the grid plate, the gravity of the medicine in the inner cavity of the medicine storage cylinder 21 drives the movable end of the grid plate to rotate downward, thereby causing the grid plate to vibrate and accelerating the speed at which the medicine falls downward from the mesh hole of the grid plate.

[0050] Further, see Figure 5-8 For the aforementioned medicine container 32, the drive source 50 includes a servo motor 501. An adjustment assembly 8 is provided inside the medicine container 32. The adjustment assembly 8 includes a bidirectional screw 81, which is sleeved on the axis of the transport roller 31. One end of the bidirectional screw 81 is rotatably connected to the conveying cylinder 22 via a bearing, and the other end extends to the outer periphery of the conveying cylinder 22 and is fixedly connected to the output end of the servo motor 501. A guide groove is provided inside the transport roller 31, communicating with the medicine container 32. The bidirectional screw 81... Both sides of the ring are threaded with a circular ring 82. Both ends of the circular ring 82 are fixedly connected to a movable plate 83. The outer periphery of the movable plate 83 is in contact with the inner wall of the medicine chamber 32. An elastic cloth 84 is fixedly connected to the top edge of the movable plate 83. One end of the elastic cloth 84 is fixedly connected to the inner wall of the medicine chamber 32. A telescopic plate 85 is fixedly installed at the connection between the movable plate 83 and the circular ring 82. The telescopic plate 85 is located on the side of the movable plate 83 away from the elastic cloth 84 and one end is fixedly connected to the conveyor roller 31. The top of the movable plate 83 is located below the sealing plate 331.

[0051] Specifically, the servo motor 501 drives the bidirectional screw 81 to rotate. Through the threaded connection between the ring 82 and the bidirectional screw 81, the two rings 82 and the moving plates 83 on both sides of the outer periphery of the rings 82 move in opposite directions or in opposite directions, thereby adjusting the volume of the medicine chamber 32. The setting of the elastic cloth 84 and the telescopic plate 85 prevents the medicine in the medicine storage cylinder 21 from falling into the guide groove cavity and the gap between the moving plate 83 and the inner wall of the medicine chamber 32.

[0052] Further, see Figure 5-8 For the aforementioned adjustment component 8, a circular groove is provided on the inner wall of the conveying cylinder 22, and a circular block 86 is fitted inside the cavity of the circular groove. A bidirectional screw 81 is fixed at the axis of the circular block 86. One side of the circular block 86 is in contact with the side of the conveying roller 31. Grooves are provided at both ends of one side of the circular block 86. A locking block 87 is slidably provided inside the groove. Multiple locking slots 88 are provided on the side of the conveying roller 31. The locking block 87 is fitted inside the cavity of the locking slot 88. One side of the locking block 87 is set as an arc surface, and the other side of the locking block 87 is set as a flat surface. A third spring 89 is installed on the side of the locking block 87 near the groove.

[0053] Both ends of one side of the conveying cylinder 22 are provided with built-in grooves 810, which extend into the inner cavity of the conveying cylinder 22. A movable rod 811 is fitted inside the inner cavity of the built-in groove 810. A stop block 812 is fixedly connected to the outer periphery of the movable rod 811. The stop block 812 is located in the inner cavity of the built-in groove 810. A fourth spring 813 is provided on one side of the stop block 812. The fourth spring 813 is fitted around the outer periphery of the movable rod 811. The groove opening of the built-in groove 810 near the outer side of the conveying cylinder 22 is set into a cross opening. A cross block 814 is fixedly connected to one end of the movable rod 811. The cross block 814 matches the cross opening. Both sides of one side of the conveying roller 31 are provided with holes and grooves 815. One end of the movable rod 811 extends into the inner cavity of the conveying cylinder 22 and is fitted into the holes and grooves 815.

[0054] Specifically, when it is necessary to adjust the volume of the medicine chamber 32, rotate the cross block 814 so that the cross block 814 aligns with the cross opening at one end of the internal groove 810, and push the cross block 814 into the inner cavity of the internal groove 810, so that the fourth spring 813 is in a compressed state, thereby causing the movable rod 811 to move towards the transport roller 31 and align with the slot 815. Then rotate the cross block 814 so that the cross block 814 is fixed in the inner cavity of the internal groove 810, thereby limiting and fixing the transport roller 31. The servo motor 501 drives the bidirectional screw 81 to rotate in the opposite direction. At this time, the transport roller 31 is fixed. The bidirectional screw 81 rotates and drives the circular block 86 to rotate. The arc surface of the locking block 87 on one side causes the locking block 87 to disengage from the locking slot 88. At this time, the third spring 89 is in a compressed state. When the locking block 87 rotates with the circular block 86 to the next locking slot 88 position, the third spring 89 restores its elasticity and makes the locking block 87 coincide with the locking slot 88. When the bidirectional screw 81 continues to rotate, the locking block 87 will repeat the above operation.

[0055] After adjusting the volume of the medicine compartment 32, the locking block 87 is aligned with one of the slots 88, and the cross block 814 is rotated so that it aligns with the cross opening at one end of the built-in slot 810. The spring force provided by the fourth spring 813 drives the cross block 814 to move outward, thereby causing one end of the movable rod 811 to disengage from the slot 815. Then, the servo motor 501 drives the bidirectional screw 81 to rotate. Since the side of the locking block 87 away from the arc surface is set as a plane and is in contact with the inner wall of the slot 88, when the bidirectional screw 81 rotates, it drives the circular block 86 to rotate. The locking block 87 drives the transport roller 31 to rotate, so that the transport roller 31 and the bidirectional screw 81 are in a state of synchronous rotation, thereby realizing the function of transporting medicine.

[0056] Further, see Figure 10 For the aforementioned transmission assembly 51, the transmission assembly 51 includes a rotating plate 511, a cavity is opened in the inner wall of the conveying cylinder 22, the cavity is connected to the rectangular groove 62, the inner wall of the cavity is rotatably connected to the rotating shaft 512 through the bearing, the rotating plate 511 is fixedly disposed on the outer periphery of the rotating shaft 512, one end of the rotating shaft 512 extends to the outer periphery of the conveying cylinder 22 and is fixedly installed with a driven gear 513, the outer periphery of the bidirectional screw 81 is fixedly connected with a driving gear 514, and a toothed belt 515 is sleeved on the outer periphery of the driving gear 514 and the driven gear 513;

[0057] Specifically, the servo motor 501 drives the bidirectional screw 81 to rotate, which in turn drives the drive gear 514 to rotate. Through the meshing connection between the drive gear 514 and the driven gear 513 and the toothed belt 515, the driven gear 513 is driven to rotate, thereby driving the rotating shaft 512 to rotate, which in turn drives the rotating plate 511 in the cavity to rotate. The rotating plate 511 is designed to be an elongated ellipse, and the axis at one end coincides with the axis of the rotating shaft 512. When the outer long end of the rotating plate 511 rotates upward, it drives the push rod 61 to move upward, thereby opening the top of the inner cavity of the conveying cylinder 22 and vibrating the grid plate.

[0058] Working principle: In use, the amount of medicine to be added at one time needs to be adjusted according to the degree of sewage pollution, i.e., the volume of the medicine tank 32 needs to be adjusted. When adjusting the volume of the medicine tank 32, rotate the cross block 814 so that the cross block 814 aligns with the cross opening at one end of the internal groove 810, and push the cross block 814 into the inner cavity of the internal groove 810, so that the fourth spring 813 is compressed. This causes the movable rod 811 to move towards the conveyor roller 31, thus aligning with the slot 815. Then rotate the cross block 814 to fix it in the internal groove. The inner cavity of 810 limits and fixes the transport roller 31. Then, the servo motor 501 drives the bidirectional screw 81 to rotate in the opposite direction. At this time, the transport roller 31 is fixed, and the bidirectional screw 81 rotates and drives the circular block 86 to rotate. Through the setting of the arc surface on one side of the locking block 87, the locking block 87 is disengaged from the locking slot 88. At this time, the third spring 89 is in a compressed state. When the locking block 87 rotates with the circular block 86 to the next locking slot 88 position, the third spring 89 restores its elasticity and makes the locking block 87 coincide with the locking slot 88. When the bidirectional screw 81 continues to rotate, the locking block 87 will repeatedly... In the above operation, the bidirectional screw 81 rotates, and through the threaded connection between the ring 82 and the bidirectional screw 81, it drives the two rings 82 and the moving plates 83 on both sides of the outer periphery of the rings 82 to move in opposite directions or in opposite directions, thereby adjusting the volume of the medicine chamber 32. The elastic cloth 84 and the telescopic plate 85 are set to prevent the medicine in the medicine storage cylinder 21 from falling into the guide groove cavity and the gap between the moving plate 83 and the inner wall of the medicine chamber 32. After the volume of the medicine chamber 32 is adjusted, the locking block 87 is aligned with one of the locking slots 88, and the cross block 814 is rotated so that the cross block 814 is aligned with the guide slot 88. The cross-shaped opening at one end of the block 814 coincides with the cross-shaped opening at the end of the built-in groove 810, and the cross-shaped block 814 is moved outward by the elastic force provided by the fourth spring 813, so that one end of the movable rod 811 is disengaged from the hole groove 815. Then, the bidirectional screw 81 is rotated by the servo motor 501. Since the side of the locking block 87 away from the arc surface is set as a plane and is in contact with the inner wall of the locking groove 88, when the bidirectional screw 81 rotates, it drives the circular block 86 to rotate, and drives the transport roller 31 to rotate through the locking block 87, so that the transport roller 31 and the bidirectional screw 81 are in a state of synchronous rotation.

[0059] After adjusting the volume of the medicine compartment 32, the servo motor 501 drives the bidirectional screw 81 to rotate, which in turn drives the drive gear 514 to rotate. Through the meshing connection between the drive gear 514 and the driven gear 513 and the toothed belt 515, the driven gear 513 is driven to rotate, thereby driving the rotating shaft 512 to rotate, which in turn drives the rotating plate 511 in the cavity to rotate. The rotating plate 511 is designed to be an elongated ellipse, and the axis at one end coincides with the axis of the rotating shaft 512. When the outer long end of the rotating plate 511 rotates, it drives the push rod 61 to move.

[0060] As the transport roller 31 rotates, during the rotation from a horizontal to a vertical position of the two medicine bins 32, the arc surface of the fixing block 334 above the sealing plate 331 contacts the curved surface of the baffle 335. Due to the slidable arrangement of the sealing plate 331 within the guide groove 332, the sealing plate 331 is retracted into the guide groove 332 during the rotation of the transport roller 31, and the first spring 333 is compressed. When the opening of the medicine bin 32 above the medicine storage cylinder 21 is directly above the medicine storage cylinder 21, the medicine storage cylinder 21 adds medicine to the medicine bin 32. The transport roller 31 continues to rotate, causing the fixing block 334 to press against the baffle 335. The arc surface of the fixing block 334 further compresses the baffle. The movable end of 335 rotates upward and compresses the torsion spring 336. When the fixed block 334 disengages from the curved surface of the baffle 335, the first spring 333 regains its elasticity and pushes the sealing plate 331 outward, thereby sealing the opening of the medicine chamber 32 and reducing the spillage of medicine in the inner cavity of the medicine chamber 32. At this time, the torsion spring 336 regains its elasticity and causes the baffle 335 to return to its original position. At the same time, when one medicine chamber 32 rotates directly upward towards the medicine storage cylinder 21, the other medicine chamber 32 rotates directly downward towards the conveying cylinder 22. At this time, the fixed block 334 on the sealing plate 331 contacts the baffle 335 below the inner wall of the conveying cylinder 22, thereby opening the medicine chamber 32 and replenishing the medicine in the inner cavity of the disinfection tank 11.

[0061] When the outer long end of the rotating plate 511 rotates downward, and the two medicine chambers 32 are in a horizontal position and rotate towards a vertical position, the rotating plate 511 no longer provides thrust to the push rod 61. At this time, the second spring 63 resets and drives the push plate to move downward. Through the movable hinge between the connecting shaft 65 and the two partitions 42, and the movable setting of the connecting shaft 65 in the inner cavity of the sliding groove 64, when the push rod 61 moves downward, it drives the movable ends of the two partitions 42 to move in opposite directions, thereby opening the top of the conveying cylinder 22 and adding medicine to the medicine chamber 32. During the movement of the push rod 61, the rack 71 moves and drives the rotating rod 72 with the toothed ring 73 to rotate. During the rotation, one of the protruding blocks 74 rotates upward and provides a pushing force to lift the movable end of the grid plate. When the protruding block 74 is separated from the grid plate, the gravity of the medicine in the inner cavity of the medicine storage cylinder 21 drives the movable end of the grid plate to rotate downward, thereby causing the grid plate to vibrate and accelerating the speed at which the medicine falls downward from the mesh hole of the grid plate.
