Description

Technical Field

[0001] This invention relates to the field of pharmaceutical equipment technology, specifically to an adjustable-height pharmaceutical granule dispensing machine. Background Technology

[0002] Granule filling machines are one of the commonly used solid dosage forms in clinical practice. They refer to dry granular dosage forms with a certain particle size and flowability, which are produced by mixing drug raw materials with appropriate excipients and then processing them through granulation, drying, and sizing. Granule filling machines are one of the commonly used equipment in the pharmaceutical process. They are specialized equipment that uses mechanical or automated control systems to dispense granular drugs into various packaging containers according to preset dosages. Their core function is to achieve quantitative distribution of granular drugs.

[0003] Chinese Patent Publication No. CN111874364B discloses an adjustable-height pharmaceutical granule dispensing machine. Its structure includes a main body, a discharge port, and a panel. A top groove is located on the top of the main body, and a locking block outside the top groove is located on the top side of the main body. A hydraulic pump is mounted on the top of the base, and a sliding plate on the top of the base is located on the side of the main body. The bottom groove has an inclined structure and is located on the top of the base. The discharge port has an inclined structure, and its side is mounted on the inner side of the main body via a rotating shaft. The top of the panel has a groove, and the bottom of the panel is mounted on the top of a sliding rod via a threaded rod. The speed of the falling medicine is controlled by adjusting the tilt angle of the discharge port, and the bottom of the medicine bottle is fixed by the panel to prevent tipping.

[0004] However, the above-mentioned existing technology has the following shortcomings: During use, although it is possible to manually adjust the bottle to match the equipment when changing to a different height, the adjustment requires stopping the machine and turning the screw with a wrench or other tools, and testing and adjusting. The efficiency is low, and the adjustment effect depends entirely on the operator's experience. If the force is not properly controlled, the height deviation between the filling head and the bottle mouth may exceed 3mm. This may cause particles to spill and contaminate the clean area, or even damage the bottle due to collision or affect the subsequent sealing quality. Summary of the Invention

[0005] The purpose of this invention is to address the problem that, while manual adjustment can be used to adapt medicine bottles of different heights to the equipment during use, this process requires stopping the machine and using tools such as wrenches to rotate the screw, followed by testing and adjustment. This is inefficient, and the adjustment effect depends entirely on the operator's experience. If the force is not properly controlled, the height deviation between the filling head and the bottle mouth can easily exceed 3mm. This can cause granule spillage and contamination of the clean area, or even damage to the medicine bottle due to collision or affect the subsequent sealing quality. Therefore, this invention provides an adjustable-height pharmaceutical granule filling machine.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable-height pharmaceutical granule dispensing machine, comprising: a support member, wherein a clamping member is provided on the support member for clamping and fixing a medicine bottle, an activation member is provided on the clamping member for controlling the clamping state of the clamping member, a positioning member is provided on the support member for automatically adjusting the height according to the height of the medicine bottle, and a dispensing member is provided on the positioning member for quantitatively dispensing granular medicine into the medicine bottle;

[0007] The support includes a base, a sleeve rotatably connected to the base, a rotating rod inserted through the sleeve, a motor fixedly connected to the bottom end of the base, the output end of the motor fixedly connected to the rotating rod, a mounting plate fixedly connected to the top end of the rotating rod, a connecting ring fixedly connected to the bottom end of the mounting plate, a rotating groove formed at the bottom end of the connecting ring, and a support rod fixedly connected to the top end of the base, with the top end of the support rod rotatably connected to the rotating groove.

[0008] The positioning component includes a mounting column fixedly connected to the top of the base. An adjustment groove is provided on the side end of the mounting column. A fixed plate is slidably connected in the adjustment groove. A sub-assembly component is provided on the fixed plate. A material picking groove is provided through the fixed plate. A linkage plate is fixedly connected to one end of the material picking groove.

[0009] When the clamping component holds the medicine bottle, the motor drives the mounting plate to rotate, which in turn causes the clamping component and the medicine bottle to rotate synchronously, so as to move the medicine bottle to below the discharge port of the dispensing component. During this transfer process, the medicine bottle will gradually move to below the linkage plate. As the rotation continues, the mouth of the medicine bottle will continuously approach the linkage plate until the bottom of the linkage plate abuts against the mouth of the medicine bottle, thereby driving the linkage plate to move accordingly in the adjustment groove, so that the distance between the mouth of the medicine bottle and the discharge port of the dispensing component remains consistent.

[0010] As a further embodiment of the present invention: the clamping member includes a mounting plate fixedly connected to the mounting plate, the top of the mounting plate having a through-hole placement groove, the top of the mounting plate having a through-hole adaptation groove, and the placement groove and the adaptation groove being connected.

[0011] As a further embodiment of the present invention: a connecting rod is slidably inserted into the side end of the mounting plate, a clamping block is slidably inserted into the adaptation groove, one end of the connecting rod is fixedly connected to the clamping block, and the other end of the connecting rod is fixedly connected to a connecting plate.

[0012] As a further embodiment of the present invention: a spring is sleeved on the outside of the connecting rod, one end of the spring is fixedly connected to the connecting plate, and the other end of the spring is fixedly connected to the mounting plate.

[0013] As a further embodiment of the present invention: the activator includes an activation ring rotatably connected to the outside of the mounting plate, the activation ring having a linkage groove on its outer side, the activation ring abutting against an inner edge of the connecting plate, a linkage block being fixedly connected to the inner side of the connecting plate, and the linkage block being slidably connected to the linkage groove.

[0014] As a further embodiment of the present invention: a slot is provided through the mounting plate, a telescopic rod is fixedly connected to the top of the base, an activation block is fixedly connected to the top of the telescopic rod, and the activation block is adapted to the slot.

[0015] As a further embodiment of the present invention: a second spring is sleeved on the outside of the telescopic rod, one end of the second spring is fixedly connected to the bottom end of the activation block, and the other end of the second spring is fixedly connected to the top end of the base.

[0016] As a further embodiment of the present invention: the sub-assembly includes a mounting frame fixedly connected to the top of the fixed plate, a storage cylinder fixedly connected to the top of the mounting frame and communicating with the mounting frame, a closed disc rotatably connected inside the mounting frame, a discharge hole through the top of the closed disc, a scraper block fixedly connected inside the storage cylinder and the bottom end of the scraper block abutting against the top of the closed disc.

[0017] As a further embodiment of the present invention: a second motor is fixedly connected to the top of the fixed plate, the output end of the second motor passes through the mounting frame and is fixedly connected to the closed disc, an inlet hole is opened through the top of the fixed plate, a discharge pipe is provided on the mounting frame, one end of the discharge pipe passes through the mounting frame and abuts against the bottom end of the closed disc, the other end of the discharge pipe is located directly above the inlet hole, and a speed reduction block is fixedly connected to the inner wall of the discharge pipe.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. In this invention, the dynamic contact between the spiral linkage plate and the mouth of the medicine bottle drives the fixed plate to slide along the adjustment groove, so that the distance between the linkage plate and the mounting plate automatically adapts to the height of the medicine bottle, ensuring that the distance between the dispensing outlet and the bottle mouth is always consistent, avoiding particle spillage or inaccurate dosage due to height deviation. It can adapt to medicine bottles of different heights without stopping the machine for adjustment, improving production continuity and adaptability.

[0020] 2. In this invention, four sets of evenly distributed clamping blocks move synchronously radially under the drive of a spring, achieving adaptive clamping of medicine bottles of different diameters. At the same time, the mechanical structure of four-point synchronous clamping automatically centers the medicine bottle, ensuring that the axis of the medicine bottle is precisely aligned with the dispensing port, avoiding overpressure damage caused by the size tolerance of the medicine bottle, and improving dispensing accuracy and stability of the medicine bottle.

[0021] 3. In this invention, the mechanical coupling between the activation block and the activation ring is used to drive the activation block to rise and fall by means of the oblique pressure generated by the rotation of the mounting plate. In conjunction with the difference in elastic force between spring 2 and spring 1, the activation ring is automatically triggered to rotate, thereby realizing the radial extension and retraction of the clamping block. This allows the clamping and release states of the medicine bottle to switch automatically with the operation of the equipment, eliminating the need for an independent control unit, simplifying the operation process and improving the reliability of the system.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0034] Reference Figures 1 to 3 In this embodiment of the invention, a height-adjustable pharmaceutical granule dispensing machine includes: a support member 1, a clamping member 3 for clamping and fixing medicine bottles on the support member 1, multiple sets of clamping members 3 being evenly distributed on the support member 1, an activation member 4 for controlling the clamping state of the clamping member 3 on the clamping member 3 to facilitate putting the medicine bottle into or taking out the clamping member 3, a positioning member 2 for automatically adjusting the height according to the height of the medicine bottle on the support member 1 to adapt to medicine bottles of different heights, and a dispensing member 5 for quantitatively dispensing granular medicine into the medicine bottle on the positioning member 2;

[0035] The device consists of multiple sets, surrounding one set of robotic arms. Within the working area formed by these multiple sets of devices, there are two sets of conveyors: one set of conveyors is used to transport empty medicine bottles, and the other set of conveyors is used to transport medicine bottles that have been filled with medicine.

[0036] The support component 1 includes a base 11, on which a sleeve 12 is rotatably connected. The sleeve 12 is I-shaped and has a cross-shaped through groove inside. A rotating rod 14 is inserted through the cross-shaped through groove in the sleeve 12. The rotating rod 14 is cross-shaped. A motor 13 is fixedly connected to the bottom end of the base 11. The output end of the motor 13 is fixedly connected to the rotating rod 14. A mounting plate 15 is fixedly connected to the top end of the rotating rod 14. A connecting ring 16 is fixedly connected to the bottom end of the mounting plate 15. A rotating groove 17 is T-shaped at the bottom end of the connecting ring 16. A support rod 18 is fixedly connected to the top end of the base 11. The support rod 18 is T-shaped and its top end is rotatably connected to the rotating groove 17. Multiple sets of support rods 18 are provided and evenly distributed on the base 11.

[0037] Reference Figure 4 The positioning component 2 includes a mounting post 21 fixedly connected to the top of the base 11. Three sets of mounting posts 21 are evenly distributed at the top of the base 11. Each set of mounting posts 21 has an adjustment groove 22 on its side. A fixing plate 23 is slidably connected within the adjustment groove 22. A mounting plate 15 is positioned below the fixing plate 23, with its outer edge located within the adjustment groove 22 but not in contact with its inner wall. A dispensing component 5 is provided on the fixing plate 23. A material-retrieving groove 24 is formed through the fixing plate 23. The size of the material-retrieving groove 24 is larger than the maximum diameter of a set of clamping components 3. One end of the material-retrieving groove 24 is fixedly connected to… There is a linkage plate 25, which is spiral in shape. The highest point of the spiral linkage plate 25 faces the clamping member 3 located below the material feeding groove 24. When the medicine bottle rotates with the clamping member 3 and enters below the linkage plate 25, the height of the linkage plate 25 and the mouth of the medicine bottle gradually decreases with the spiral structure. The mouth of the medicine bottle will gradually approach the linkage plate 25 until the two touch. When the medicine bottle continues to move, it will drive the linkage plate 25 to move synchronously, which in turn drives the fixing plate 23 to slide along the adjusting groove 22. Finally, the distance between the linkage plate 25 and the mounting plate 15 is consistent with the height of the medicine bottle, so as to realize the height matching between the dispensing component 5 and the medicine bottle.

[0038] The above solution ensures that the distance between the dispensing port of the dispensing component 5 and the mouth of the medicine bottle is always consistent through the dynamic contact between the spiral linkage plate 25 and the medicine bottle and the sliding of the fixing plate 23, thus avoiding particle spillage or inaccurate dosage due to height deviation. Multiple sets of mounting columns 21 form a stable support. The sliding structure of the adjusting groove 22 and the fixing plate 23, combined with the spiral design of the linkage plate 25, can synchronously respond to the height requirements of medicine bottles of different sizes without stopping the machine to replace parts, reducing manual intervention.

[0039] Reference Figure 5The clamping component 3 includes a mounting plate 31 fixedly connected to the mounting plate 15. A placement groove 32 for medicine bottles is formed through the top of the mounting plate 31. The placement groove 32 is a circular groove. An adaptation groove 33 is formed through the top of the mounting plate 31, and the placement groove 32 communicates with the adaptation groove 33. Four sets of adaptation grooves 33 are provided, evenly distributed on the sides of the adaptation grooves 33. Connecting rods 34 are slidably inserted into the sides of the mounting plate 31. Multiple sets of connecting rods 34 are provided, and every two sets of connecting rods 34 are inserted through and into one set of adaptation grooves 33. Clamping blocks 35 are slidably inserted into the adaptation grooves 33. Each set of adaptation grooves 33 contains one set of clamping blocks 35. One end of the connecting rod 34 is fixedly connected to the clamping block 35, and the other end of the connecting rod 34 is fixedly connected to a connecting plate 36. Each set of clamping blocks 35... The holding block 35 is fixedly connected to the connecting plate 36 and two sets of connecting rods 34. Each set of connecting rods 34 is fitted with a set of springs 37 on the outside. One end of the springs 37 is fixedly connected to the connecting plate 36, and the other end of the springs 37 is fixedly connected to the mounting plate 31. When the external driving force pushes the connecting plate 36 to move outward against the elastic force of the springs 37, the connecting plate 36 drives the clamping block 35 to retract radially into the adaptation groove 33 through the connecting rods 34, and the placement groove 32 is fully open. At this time, the medicine bottle can be put in or taken out. When the external driving force is released, the springs 37 return to their original position and pull the connecting plate 36 inward. The connecting rods 34 simultaneously push the clamping block 35 to move towards the center of the placement groove 32 until the inner side of the clamping block 35 is tightly attached to the outer wall of the medicine bottle, so as to achieve four-point synchronous radial clamping and fixing.

[0040] The above scheme achieves automatic centering and clamping of the medicine bottle by synchronous radial movement of four evenly distributed clamping blocks 35 driven by spring 37, ensuring precise alignment of the medicine bottle axis with the dispensing port. The spring energy storage mechanism enables adaptive adjustment of the clamping force, avoiding overpressure damage to the medicine bottle due to dimensional tolerances. The purely mechanical clamping and releasing action does not require an independent power source, and the structure is compact and highly reliable.

[0041] Reference Figures 6 to 8The activation component 4 includes an activation ring 41 rotatably connected to the outside of the mounting plate 31. The activation ring 41 consists of a set of circular rings and four sets of sector blocks fixedly connected to the outside of the circular rings. The sector blocks are roughly triangular, with the hypotenuse corresponding to the triangle being an arc surface. The arc surface of each set of sector blocks abuts against one edge of the inner side of a set of connecting plates 36. Each set of sector blocks in the activation ring 41 has a set of linkage grooves 42 on its outer side, and the linkage grooves 42 extend along the arc surface of the sector blocks. The linkage grooves 42 are U-shaped. Each set of connecting plates 36 has a linkage block 43 fixedly connected to its inner side. The linkage block 43 is U-shaped. The linkage block 43 is slidably connected to the linkage groove 42. A slot 44 is provided through the mounting plate 15. Four sets of slots 44 are provided, each set matching a set of clamping parts 3. A telescopic rod 46 is fixedly connected to the top of the base 11, and the telescopic rod 46 is located in the lower material receiving groove 24. Three sets of telescopic rods 46 are provided, and an activation block 45 is fixedly connected to the top of each set of telescopic rods 46. The activation block 45 is adapted to the slot 44. The activation block 45 is roughly triangular, with two beveled apexes at its top. The activation block 45 is arc-shaped when viewed from above. A set of springs is sleeved on the outer side of each set of telescopic rods 46. Spring 47, one end of which is fixedly connected to the bottom end of activation block 45, and the other end of which is fixedly connected to the top end of base 11, has a greater elastic force than spring 37. When activation block 45 rises and penetrates slot 44 under the elastic force of spring 47, one side of the apex of its triangular shape abuts against the bottom edge of the fan-shaped block of activation ring 41, pushing activation ring 41 to rotate around mounting plate 31. During rotation, the arc surface of the fan-shaped block continuously presses against the inner edge of connecting plate 36, forcing connecting plate 36 to move outward against the elastic force of spring 37. When the connecting rod 34 is in conjunction with the four sets of clamping blocks 35, they are fully retracted into the adaptation groove 33. At this time, the clamping part 3 is in the open state. When the mounting plate 15 rotates and the edge of the slot 44 contacts the other side of the inclined surface of the activation block 45, the activation block 45 is subjected to oblique pressure and moves down and compresses the second spring 47, disengaging from the contact with the activation ring 41. At this time, the first spring 37 resets and pulls the connecting plate 36 inward. At the same time, the activation ring 41 rotates under the reverse abutment action of the arc surface of the fan-shaped block and the edge of the connecting plate 36, driving the clamping block 35 to move from the adaptation groove 33 to the center of the placement groove 32 until the medicine bottle is clamped.

[0042] The above scheme achieves automatic switching of the clamping state through the mechanical coupling of the double-sloped activation block 45 and the spiral curved activation ring 41. The inclined surface abuts to trigger rotational motion, and the arc surface conversion transforms linear displacement into radial clamping action. The difference in elastic force between spring 2 47 and spring 1 37 ensures that the activation block 45 is preferentially lifted to trigger the opening action, while the downward pressure can accurately overcome spring 2 47 to achieve release. The sliding cooperation between the convex linkage block 43 and the linkage groove 42 forces the connecting plate 36 and the activation ring 41 to move synchronously, eliminating action lag. The entire activation process is completely driven by the rotation of the device, without the need for an independent control unit, which greatly improves the reliability of the system.

[0043] Reference Figure 9 The packaging component 5 includes a mounting frame 51 fixedly connected to the top of the fixed plate 23. A storage cylinder 52 is fixedly connected to the top of the mounting frame 51, and the storage cylinder 52 is connected to the mounting frame 51. A sealing disc 53 is rotatably connected inside the mounting frame 51. A discharge hole 54 is opened through the top of the sealing disc 53. Multiple sets of discharge holes 54 are evenly distributed at the top of the sealing disc 53. The bottom of the discharge hole 54 abuts against the mounting frame 51 to prevent drug leakage. A scraper block 55 is fixedly connected inside the storage cylinder 52. The width of the scraper block 55 is larger than the diameter of the discharge hole 54, and the bottom of the scraper block 55 abuts against the top of the sealing disc 53. A second motor 56 is fixedly connected to the top of the fixed plate 23. The output end of the second motor 56 passes through the mounting frame 51 and is fixedly connected to the sealing disc 53. An inlet hole 59 is opened through the top of the fixed plate 23. The inlet hole 59 is conical. A discharge pipe 57 is provided on the mounting frame 51. One end of the discharge pipe 57 passes through the mounting frame 51 and is connected to the sealing disc 53. 3. The bottom end abuts against the material, and the other end of the discharge pipe 57 is located directly above the inlet hole 59. The through hole of the discharge pipe 57 and the mounting bracket 51 is located directly below a set of discharge holes 54, and the inner diameter of the discharge pipe 57 is larger than that of the discharge holes 54. The scraper block 55 is located directly above this set of discharge holes 54. A speed reduction block 58 is fixedly connected to the inner wall of the discharge pipe 57. The speed reduction block 58 is an annular block with a triangular cross-section. When the motor 2 56 drives the closed disc 53 to rotate, the granular medicine in the storage cylinder 52 falls. The medicine is fed into the discharge hole 54 at the top of the closed disc 53. During the rotation, the scraper block 55 fixed to the bottom of the storage cylinder 52 scrapes off the excess medicine that exceeds the depth of the discharge hole 54, ensuring that each discharge hole 54 retains only a fixed amount of medicine. When the discharge hole 54 filled with medicine rotates to directly above the discharge pipe 57, the medicine falls into the discharge pipe 57 under the action of gravity. After being buffered and decelerated by the annular deceleration block 58 on the inner wall of the discharge pipe 57, it falls precisely into the medicine bottle below through the conical inlet hole 59.

[0044] The above solution achieves precise volumetric metering of granular medicine through the combination of rotating closed disc 53 and fixed scraper block 55. The scraping action simultaneously completes filling and trimming. The inclined structure of the annular deceleration block 58 inside the discharge pipe 57 reduces the falling speed of the medicine and prevents granules from splashing or breaking. The design of the bottom end of the closed disc 53 tightly abutting against the mounting frame 51, combined with the mechanism that the discharge hole 54 only opens when aligned with the discharge pipe 57, eliminates medicine leakage. The entire dispensing process requires only a single motor drive, resulting in a compact structure and high metering stability.

[0045] The working principle of this invention is as follows: In the initial state, multiple sets of clamping members 3 are distributed at equal intervals on the mounting plate 15. The bottom end of the fixing plate 23 contacts the top end of the remaining clamping members 3 except for the set directly below the material picking groove 24. The clamping members 3 directly below the material picking groove 24 do not contact the fixing plate 23. The activation block 45, supported by the second spring 47, penetrates the slot 44. One of its inclined surfaces contacts the bottom edge of a set of fan-shaped blocks in the activation ring 41. Under the contact action, the activation ring 41 rotates, and the arc surface of the fan-shaped block pushes the connecting plate 36 to move outward. The first spring 37 is stretched, and the clamping block 35 completely enters the adaptation groove 33. At this time, the robot grabs a set of medicine bottles on the conveyor conveyor of empty medicine bottles and puts the medicine bottles into the placement groove 3 of the set of clamping members 3 through the material picking groove 24. In step 2, motor 13 is then started. The output of motor 13 drives the rotating rod 14 to rotate, which in turn drives the mounting plate 15 to rotate. The clamping part 3 and the medicine bottle rotate synchronously with the mounting plate 15. During the movement, the slot 44 contacts the other inclined surface of the activation block 45. After being pressed, the activation block 45 overcomes the elastic force of the second spring 47 and moves downward. The second spring 47 contracts until the activation block 45 is completely under the mounting plate 15 and contacts the bottom end of the mounting plate 15. As the activation block 45 moves downward, the stretched spring 37 begins to reset. Under the tension of the spring 37, the connecting plate 36 moves inward. At the same time, under the contact action of the arc surface of the fan-shaped block and an inner edge of the connecting plate 36, the activation ring 41 rotates in the opposite direction to reset. The clamping block 35 moves from the adaptive The groove 33 moves into the placement groove 32. When the activation block 45 is completely below the mounting plate 15, the clamping block 35 contacts the medicine bottle in the placement groove 32, fixing the medicine bottle and centering it. The medicine bottle continues to rotate with the mounting plate 15, entering below the spiral linkage plate 25. Because the linkage plate 25 is spiral, its height relative to the bottle opening gradually decreases, and the bottle opening gradually approaches the linkage plate 25 until the bottom of the linkage plate 25 contacts the bottle opening. After contact, the continuous movement of the medicine bottle drives the linkage plate 25 to move, which in turn drives the fixing plate 23 to slide within the adjustment groove 22, ultimately making the distance between the linkage plate 25 and the mounting plate 15 equal to the height of the medicine bottle. As the movement continues, when the bottle opening moves to the inlet hole 59... When directly below, motor 13 stops, keeping the medicine bottle stationary. Then, motor 2 56 is started, and its output drives the closed disc 53 to rotate. The granular medicine in the storage cylinder 52 falls into the discharge hole 54 of the closed disc 53. When the closed disc 53 rotates until a discharge hole 54 aligns with the discharge pipe 57, the scraper block 55 scrapes away excess medicine from this discharge hole 54. The medicine in this discharge hole 54 enters the discharge pipe 57, passes through the deceleration block 58 in the discharge pipe 57, and then falls into the medicine bottle below through the inlet hole 59. After the medicine bottle is filled, it continues to rotate with the mounting plate 15, returning to directly below the feeding trough 24. At this time, the activation block 45 contacts the activation ring 41 of the clamping component 3 again, causing the clamping block 35 to retract back into the adaptation groove 33.The medicine bottles are no longer fixed. The robotic arm picks up the filled medicine bottles and transfers them to another set of conveyors for transport to the next stage. This process is repeated to achieve continuous granular medicine dispensing. Through the dynamic contact between the spiral linkage plate 25 and the bottle opening, the fixing plate 23 slides along the adjusting groove 22, automatically adapting the distance between the linkage plate 25 and the mounting plate 15 to the bottle height. This ensures that the distance between the dispensing component 5's outlet and the bottle opening remains consistent, preventing granule spillage or inaccurate dosage due to height deviation. It can accommodate bottles of different heights without requiring machine stoppage for adjustment, improving production continuity and adaptability. The synchronous radial movement of four evenly distributed clamping blocks 35 driven by spring 37 further enhances this process. This device enables adaptive clamping of medicine bottles of different diameters. Simultaneously, a four-point synchronous clamping mechanism automatically centers the bottles, ensuring precise alignment between the bottle axis and the dispensing port. This prevents overpressure damage caused by bottle dimensional tolerances, improving dispensing accuracy and bottle stability. Through the mechanical coupling of the activation block 45 and the activation ring 41, the oblique pressure generated by the rotation of the mounting plate 15 drives the activation block 45 to rise and fall. Combined with the difference in elasticity between spring 47 and spring 37, this automatically triggers the rotation of the activation ring 41, achieving radial extension and retraction of the clamping block 35. This allows the clamping and release states of the medicine bottles to automatically switch as the equipment operates, eliminating the need for a separate control unit, simplifying the operation process, and improving system reliability.
