Description

Technical Field

[0001] This invention relates to the field of drug dispensing equipment technology, and in particular to a self-feeding device for injectable drugs and an automated extraction device for injectable drugs. Background Technology

[0002] The preparation of injectable medications is an indispensable part of drug production, hospital pharmacies, and clinical treatment. Traditional dispensing equipment has many shortcomings in the bottle feeding and medication extraction processes, especially in terms of automated bottle handling, which faces numerous challenges. Currently, most dispensing equipment relies heavily on manual operation for bottle feeding. Operators need to manually place each bottle into the dispensing machine, which is not only inefficient but also prone to inaccurate bottle placement due to human error, thus affecting subsequent medication extraction and preparation. Furthermore, manual feeding increases the frequency of operator contact with the bottles, potentially negatively impacting their hygiene.

[0003] To address the inefficiency of manual dispensing, some medication dispensing equipment uses jig modules to hold multiple medicine bottles before placing them into the dispensing machine for extraction. However, this jig module placement method also has significant drawbacks. First, the use of jig modules increases the complexity and cost of the equipment, requiring additional devices for bottle placement and fixation. Second, when placing bottles placed in jig modules into the dispensing machine, precise positioning and adjustment are often necessary; otherwise, bottles may become stuck or fail to proceed to the next step. Furthermore, the use of jig modules limits the type and size of medicine bottles; different sizes of bottles may require different jig modules, further increasing the equipment's operating cost and complexity.

[0004] For example, Chinese utility model patent CN221797014U discloses a hospital ampoule dispensing machine. This utility model achieves innovative technologies for cutting the ampoule neck and breaking the ampoule head, with a compact structure and small footprint. However, in this solution, the turntable assembly is used to clamp the ampoule and transport it to the subsequent station for breaking and liquid extraction. The process of feeding the ampoule to the turntable assembly still requires manual feeding. Similarly, Chinese utility model patent CN222517314U discloses a maintenance-friendly dispensing device, and Chinese invention patent CN119771228A discloses an intelligent dispensing device for tumor chemotherapy drugs. Both require manual means to load different sizes of medicine bottles into the fixed slots on the rotating plate before the medicine can be extracted.

[0005] While the Chinese utility model patent CN222828829U discloses an automated drug dispensing system, which includes a bottle storage unit, the loading and transfer of bottles between different components rely on a robotic arm. This results in high precision requirements and equipment costs, and the operation and debugging processes are cumbersome. In contrast, the Chinese invention patent CN112263479A discloses an intravenous drug preparation robot that utilizes multi-batch drug jigs and automated processing to achieve efficient and accurate drug preparation and a safe working environment. However, this solution uses jig modules for loading the ampoule, dissolving agent, and powder. These modules position and fix the corresponding bottles for subsequent processing. The placement of bottles on the jig modules still relies on manual labor or conventional mechanical equipment that simulates manual labor, further increasing labor costs.

[0006] Secondly, existing equipment, such as the Chinese utility model patent CN221797014U which discloses a hospital ampoule dispensing machine, has a fixed cutter wheel position when cutting bottle necks. For cutting different bottle sizes, the cutter wheel position can only be adjusted adaptively based on the conditions of the attached movable base, resulting in poor adaptability. After cutting, when breaking the bottle neck, existing equipment, such as the ampoule bottle processing assembly disclosed in Chinese invention patent CN105329827A and the hospital ampoule dispensing machine disclosed in Chinese utility model patent CN221797014U, uses a single movable breaking rod or L-shaped breaking device seat to push the bottle neck. There is no subsequent processing of the broken bottle neck portion; it is allowed to fall naturally, which is not conducive to collection and may cause fragments to form at the break point, easily falling into the bottle and causing problems.

[0007] In summary, existing drug dispensing equipment suffers from problems such as low efficiency of manual operation, complex and costly module placement and operation, and poor applicability in the drug bottle feeding and liquid extraction stages. These problems seriously affect the automation level and overall performance of the drug dispensing equipment and urgently need to be solved through technological innovation.

Simultaneously, the automated process significantly shortens dispensing time and improves efficiency, meeting the needs of large-scale production or clinical treatment, and is particularly suitable for scenarios requiring high aseptic properties in medication preparation.

[0023] 5. The detachable design of the medicine bottle compartment and the versatility of the feeding channel enable this invention to adapt to medicine bottles of different sizes without requiring large-scale modifications or replacement of parts.

Detailed Implementation

[0035] 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.

[0036] like Figure 1 , 2 As shown in Embodiment 1, a self-feeding device for injectable drugs includes a support 1, a lower housing 2 fixedly mounted on the support 1, a feeding channel 3 on the lower housing 2, and a vial release assembly 4 on the side wall of the feeding channel 3. The vial release assembly 4 is driven by a drive mechanism 5 fixedly mounted inside the lower housing 2. Driven by the drive mechanism 5, the vial release assembly 4 can release vials entering the feeding channel 3 one by one, allowing the vials to exit one by one from the feeding channel 3. A vial compartment 6 is detachably mounted on the lower housing 2, and the outlet of the vial compartment 6 corresponds to the feeding channel 3, allowing vials to enter the feeding channel 3 from the vial compartment 6. The feeding channel 3 provides a guiding channel for the movement and feeding of vials. The vial compartment 6 is used to hold vials. In this embodiment, the vial compartment 6 is open, making it easy to observe the number of vials in the vial compartment 6 and to add vials into the vial compartment 6. The medicine bottle compartment 6 has an opening on one side corresponding to the feeding channel 3. Medicine bottles are placed in the medicine bottle compartment 6 in an arranged and stacked manner. The medicine bottle compartment 6 is set at an angle, so that the medicine bottles arranged and stacked in the medicine bottle compartment 6 can slide down the bottom surface of the inclined medicine bottle compartment 6 under the action of gravity, enter the feeding channel 3 through the opening on one side of the medicine bottle compartment 6, and slide down through the feeding channel 3 to achieve automatic feeding.

[0037] Example 2: A self-feeding device for injectable drugs, based on Example 1, such as... Figure 2 As shown, the two side walls of the opening on the medicine bottle compartment 6 are respectively provided with an arc-shaped guide surface 62 and a guide slope 63. The arc-shaped guide surface 62 and the guide slope 63 are used to guide the medicine bottles smoothly from the medicine bottle compartment 6 into the discharge channel 3. In this embodiment, the arc-shaped guide surface 62 and the guide slope 63 are asymmetrically arranged on both sides of the discharge direction of the medicine bottle compartment 6, so as to guide the medicine bottles as they slide down the inclined inner wall of the medicine bottle compartment 6, which facilitates the movement of the medicine bottles and avoids the medicine bottles from accumulating at the opening of the medicine bottle compartment 6, causing jamming and causing the problem of poor discharge.

[0038] In addition, specifically in this embodiment, such as Figure 2 , 3 As shown, the lower housing 2 includes a triangular base 21 fixed to the support 1 by bolts. A receiving housing 22 is provided on the inclined surface of the triangular base 21. A discharge channel 3 is opened on the receiving housing 22. The receiving housing 22 is provided with a flared opening 23 for cooperating with the medicine bottle compartment 6. The bottom plate of the medicine bottle compartment 6 is in contact with the inclined surface of the triangular base 21. The outer walls of the curved guide surface 62 and the guide inclined surface 63 of the medicine bottle compartment 6 correspond to the two side walls of the flared opening 23, respectively. The flared opening 23 and the inclined surface of the triangular base 21 jointly support the medicine bottle compartment 6 containing the medicine bottles. The discharge channel 3 includes a U-shaped channel section 31 that cooperates with the flared opening 23. The U-shaped channel section 31 is connected to a discharge pipe 32 provided on the lower side of the inclined surface of the triangular base 21. The discharge pipe 32 is arranged vertically or inclined to facilitate discharge.

[0039] As a further specific implementation method, such as Figure 2 , 3 As shown in Figure 4, the medicine bottle release assembly 4 includes a baffle plate 41 and a pusher plate 42 that are slidably disposed parallel to each other on the lower housing 2. Both the baffle plate 41 and the pusher plate 42 are connected to the drive mechanism 5. The lower housing 2, corresponding to the side wall of the discharge channel 3, has openings that allow the baffle plate 41 and the pusher plate 42 to extend. The baffle plate 41 and the pusher plate 42 can slide alternately back and forth in the discharge channel 3 under the drive of the drive mechanism 5. Specifically, in this embodiment, the baffle plate 41 is slidably disposed laterally between the flared opening 23 and the U-shaped channel portion 31, and can close or open the connection between the two by sliding. The pusher plate 42 is laterally disposed at the middle connection of the U-shaped channel portion 31. Furthermore, the pusher plate 42 is provided with a receiving groove I 43 for cooperating with individual medicine bottles. Medicine bottles entering one side of the U-shaped flow channel 31 slide into the receiving groove I 43 one by one. When the pusher plate 42 moves laterally, it drives the medicine bottles entering the receiving groove I 43 to move laterally and enter the other side of the U-shaped flow channel 31. The bottom opening of the other side of the U-shaped flow channel 31 is connected to the discharge pipe 32 through the opening. When the medicine bottle is pushed laterally into the other side of the U-shaped flow channel 31 by the pusher plate 42, it automatically slides down, twists its posture, and falls into the discharge pipe 32 under the action of gravity. The flow channel structure space on the other side of the U-shaped flow channel 31 provides the movement space for the medicine bottle to twist its posture during the falling process. When the pusher plate 42 moves laterally, the pusher plate 42 itself closes one side of the U-shaped flow channel 31 to prevent other medicine bottles from falling, thereby realizing the feeding of medicine bottles one by one.

[0040] In addition, a positioning pin I24 is fixedly installed on the receiving shell 22 of the lower shell 2, and a locking hole is opened on the medicine bottle compartment 6 to allow the positioning pin I24 to be inserted. When the medicine bottle compartment 6 needs to be replaced, the positioning pin I24 is used in conjunction with the locking hole to lock or release the position of the medicine bottle compartment 6.

[0041] As an optional feature, the lid of the medicine bottle compartment 6 is open, allowing medicine bottles to be manually placed into the compartment in batches without removing it. Additionally, as... Figure 7 As shown, to facilitate smooth feeding of medicine bottles of different sizes, an arc-shaped guide surface 62 is separately set on the auxiliary housing 65. The auxiliary housing 65 is provided with a plug-in post 66, and the receiving housing 22 is provided with a through hole for inserting the plug-in post 66. In actual use, the auxiliary housing 65 is fitted onto the medicine bottle compartment 6, with the guide slope 63 located on both sides of the opening of the medicine bottle compartment 6. Then, the plug-in post 66 is inserted into the through hole on the receiving housing 22 to achieve a stable connection. Finally, the position of the medicine bottle compartment 6 is locked by the positioning pin I 24. In this embodiment, to ensure smooth feeding of medicine bottles of different sizes, multiple auxiliary housings 65 of different sizes are provided. When it is necessary to hold medicine bottles of different sizes, the auxiliary housing 65 of different sizes is replaced, and the arc-shaped guide surface 62 of different curvatures and sizes on it meets the feeding and guiding requirements of medicine bottles of different sizes.

[0042] As a further optional implementation, such as Figure 6 As shown, the upper end of the feeding tube 32 is a conical tube 321, and the lower end of the conical tube 321 is a circular tube 322. The conical tube 321 can guide the medicine bottle falling into it, and the circular tube 322 can restrict the falling path and falling posture of the medicine bottle to a certain extent, so that it can fall in a centered and vertical posture. In this embodiment, one side of the upper end of the conical tube 321 is hinged to the lower slope of the triangular base 21, so that the feeding tube 32 can be folded up as a whole, providing space for easy debugging and maintenance. The triangular base 21 is provided with a positioning pin II 323 that cooperates with the other side of the upper end of the conical tube 321. The positioning pin II 323 is used to lock the position of the feeding tube 32.

[0043] Example 3: A self-feeding device for injectable drugs. Based on Example 2, as a first optional specific implementation, the driving mechanism 5 includes a pair of driving motors fixedly mounted on the lower housing 2. The driving ends of the two driving motors are respectively connected to the baffle plate 41 and the pusher plate 42. The two driving motors can drive the baffle plate 41 and the pusher plate 42 to slide alternately back and forth, so that the baffle plate 41 and the pusher plate 42 can respectively block and push the medicine bottle under the drive of the driving motor, realizing the release and feeding of the medicine bottle one by one.

[0044] In this embodiment, the output shafts of the two drive motors can be connected to the baffle plate 41 and the pusher plate 42 respectively through a conventional cam mechanism 34, a gear pair, or a gear rack transmission mechanism. The two drive motors are electrically connected to the controller, which can be a conventional single-chip microcomputer. The controller controls the speed and start-stop cycle of the two drive motors, thereby driving the baffle plate 41 and the pusher plate 42 to slide back and forth alternately to realize the feeding process.

[0045] As a second optional specific implementation method, such as Figure 2 , 4 As shown in Figure 5, the drive mechanism 5 includes a dual-head drive motor 33 fixedly mounted on the lower housing 2. Both output ends of the output shaft of the dual-head drive motor 33 are provided with cam mechanisms 34, which are respectively connected to the baffle plate 41 and the pusher plate 42 through the two cam mechanisms 34. When the output shaft of the dual-head drive motor 33 rotates, the cam mechanisms 34 at both ends drive the baffle plate 41 and the pusher plate 42 to slide back and forth alternately to realize material feeding.

[0046] Specifically, in the two optional embodiments described above, the cam mechanism 34 connected to the pusher plate 42 includes a wheel 421 fixedly mounted on the output shaft of the dual-head drive motor 33 or the output shaft of the drive motor. The wheel 421 has a guide post I 422, and the pusher plate 42 has an elongated hole I 423. The guide post I 422 slides through the elongated hole I 423, wherein the length direction of the elongated hole I 423 is perpendicular to the sliding direction of the pusher plate 42. The wheel 421 rotates under the drive of the output shaft, thereby causing the guide post I 422 to move in a circular motion around the axis of the output shaft, thus causing the guide post I 422 to reciprocate within the elongated hole I 423, simultaneously causing the pusher plate 42 to slide reciprocally. The reciprocating cycle of the pusher plate 42 is adjusted by the speed of the dual-head drive motor 33 or the drive motor.

[0047] The cam mechanism 34 connected to the baffle plate 41 includes a rocker arm 411. In this embodiment, to improve space utilization, an elongated hole II 412 is provided on the baffle plate 41 along the sliding direction of the baffle plate 41. The output shaft of the drive motor or dual-head drive motor 33 passes through the elongated hole II 412. When the baffle plate 41 slides, the output shaft and the elongated hole II 412 can slide relative to each other. The rocker arm 411 is located outside the baffle plate 41, and a guide post II 413 is provided on the rocker arm 411. A push block 414 is fixedly provided on the outside of the baffle plate 41, and an elongated hole III 415 is provided on the push block 414. The guide post II 413 slides through the elongated hole III 415, and the length direction of the elongated hole III 415 is perpendicular to the sliding direction of the baffle plate 41. During operation, the rocker arm 411 rotates under the drive of the output shaft, thereby causing the guide post II 413 on it to move in a circular motion around the axis of the output shaft. This causes the guide post II 413 to reciprocate within the elongated hole III 415, while simultaneously driving the push block 414 to slide back and forth. The push block 414 then drives the baffle plate 41 connected to it to reciprocate. The reciprocating cycle of the baffle plate 41 is adjusted by the dual-head drive motor 33 or the speed of the drive motor.

[0048] As a third optional specific implementation, the drive mechanism 5 includes a pair of telescopic cylinders that are fixedly mounted in parallel on the lower housing 2. The telescopic cylinders can be conventional pneumatic telescopic cylinders or electric telescopic cylinders. The telescopic ends of the two telescopic cylinders are respectively hinged to the baffle plate 41 and the pusher plate 42. By controlling the telescopic movement of the telescopic ends of the telescopic cylinders, the baffle plate 41 and the pusher plate 42 are driven to slide back and forth alternately.

[0049] As a further specific embodiment, the end of the baffle plate 41 is provided with a protruding structure 64 for pushing the medicine bottle. When the baffle plate 41 slides, the protruding structure 64 at its end can push the medicine bottles piled at the opening of the medicine bottle compartment 6 to move, avoiding jamming and making the feeding smooth. In this embodiment, the protruding structure 64 can be a stepped protrusion or a sloped protrusion, which can contact the medicine bottle and push it to move. Furthermore, a track groove 44 is provided on the lower housing 2, and rollers 45 are provided on both the baffle plate 41 and the pusher plate 42. The rollers 45 cooperate with the track groove 44 to realize the sliding guidance and reduce the sliding resistance of the baffle plate 41 and the pusher plate 42.

[0050] As a further optional embodiment, a replaceable actuating block 61 is hinged to the lower housing 2. The baffle plate 41 cooperates with the actuating block 61, and the actuating block 61 can be activated when the baffle plate 41 slides. An opening is provided on the guide slope 63 to allow the actuating block 61 to pass through. During the movement of the baffle plate 41, it pushes the actuating block 61 to rotate around the hinged part by a certain angle. The outer end of the actuating block 61 can actuate the medicine bottles in the medicine bottle compartment 6, so that the medicine bottles in the medicine bottle compartment 6 enter the feeding channel 3 in a peristaltic and micro-movement manner, further improving the smoothness of medicine bottle feeding. In addition, in the first and third optional embodiments of this example, a pusher block 414 is also provided on the baffle plate 41, which can move with the reciprocating sliding of the baffle plate 41. In this embodiment, the actuating block 61 corresponds to the push block 414 fixedly disposed on the outside of the baffle plate 41. As the push block 414 moves with the baffle plate 41, it contacts the actuating block 61, thereby actuating the actuating block 61 and causing it to rotate along the hinge. When the push block 414 retracts, the actuating block 61 moves in the opposite direction under the pressure of the medicine bottle in the medicine bottle compartment 6, retracting synchronously with the push block 414. In this embodiment, the actuating block 61 has various sizes and specifications. When feeding medicine bottles of different specifications, different sizes of actuating blocks 61 are replaced to adapt to the actuation degree required for feeding medicine bottles of different specifications.

[0051] Example 4: An automated injection drug extraction device, based on the above examples, such as... Figure 8 , 9 As shown, the device includes a main body 7, on which a disc feeding mechanism 8 is provided. The disc feeding mechanism 8 is the core component for transporting medicine bottles. The main body 7 is fixedly equipped with a self-feeding device for injectable drugs as described in any of the above embodiments. The lower end of the feed pipe 32 of the self-feeding device for injectable drugs is configured to cooperate with the disc feeding mechanism 8. Along the conveying direction of the disc feeding mechanism 8, the main body 7 is sequentially equipped with a cutting component 10, a bottle-breaking component 9, and a liquid extraction component 11. The cutting component 10 is used to make scratches on the neck of the medicine bottle. The bottle-breaking component 9 is used to break the bottle mouth and body apart from the scratches. The liquid extraction component 11 is used to extract the liquid from the medicine bottle. Through the coordinated work of each component, the entire process of medicine bottle feeding and liquid extraction is automated.

[0052] As a further specific implementation method, such as Figure 10 , 11As shown, the disc feeding mechanism 8 includes a central turntable 81 rotatably mounted on the equipment body 7. The lower end of the central turntable 81 is connected to a first driver 82 fixedly mounted on the equipment body 7. Specifically, in this embodiment, the central shaft of the central turntable 81 is rotatably coupled to the equipment body 7 via bearings, and the lower end of the central shaft of the central turntable 81 is coupled to the output shaft of the first driver 82 via a belt drive, chain drive, or gear drive. Thus, under the drive of the first driver 82, the central turntable 81 is driven to rotate stably, providing power for the conveying of medicine bottles along the circumferential direction of the central turntable 81.

[0053] A number of first opening and closing cylinders 83 are arranged circumferentially on the central turntable 81. Each first opening and closing cylinder 83 has a V-shaped clamping block 84 at its opening and closing end for cooperating with the medicine bottle. The V-shaped structure design of the clamping surface of the V-shaped clamping block 84 can adapt to the gripping of medicine bottles of different diameters and has a self-centering function to ensure the stability and accurate positioning of the medicine bottle during the transmission process. In addition, under the driving action of the central turntable 81, the opening and closing symmetrical center of each pair of V-shaped clamping blocks 84 moves along the circumferential trajectory. Specifically, in this embodiment, four first opening and closing cylinders 83 are arranged at equal angles along the circumference of the central turntable 81, so that after each rotation of the central turntable 81, the injectable drug self-feeding device, the cutting component 10, the bottle breaking component 9, and the liquid extraction component 11 can respectively perform one feeding, cutting, breaking, and liquid extraction process. In addition, a number of support members 87 are fixedly connected above the central turntable 81, and the support members 87 are connected to the disc panel 86. The disc panel 86 has openings that correspond to the opening and closing symmetrical center of the V-shaped clamp 84 to accommodate the falling of the medicine bottle. The disc panel 86 reduces the risk of external impurities falling into the equipment and causing contamination or damage.

[0054] In addition, the main body 7 of the equipment is equipped with a bottle gauge limiter 85 corresponding to the feeding channel 3. Specifically, in this embodiment, the axis of the bottle gauge limiter 85 corresponds to the axis of the circular tube 322 of the feeding tube 32, and both are located on the movement path of the opening and closing symmetrical center of the V-shaped clamping block 84 on the first opening and closing cylinder 83. When the medicine bottle is output from the feeding channel 3 of the self-feeding device for injectable drugs and falls from the feeding tube 32 into the disc feeding mechanism 8, the bottle gauge limiter 85 can buffer and support the falling medicine bottle, so that the medicine bottle can be stably and accurately clamped by the corresponding V-shaped clamping block 84. In this embodiment, the bottle gauge limiter 85 adopts a lead screw motor fixedly installed on the main body 7 of the equipment. The end of the lead screw shaft 88 of the lead screw motor is provided with a rubber cap 89, which can play a buffering role when the medicine bottle falls on the rubber cap 89. When the lead screw motor is working, it can move its own lead screw shaft 88 axially, thereby changing the height position of the rubber cap 89. Since the distance between the neck and the bottom of different sizes of medicine bottles is not the same, in order to facilitate the alignment of the neck of different sizes of medicine bottles with the cutting component 10, the lead screw motor is activated according to the different sizes of medicine bottles and the height position of the upper end of the lead screw shaft 88 is adjusted, thereby changing the support height of the medicine bottle to facilitate subsequent clamping and cutting alignment operations.

[0055] In addition, as a further optional implementation, in this embodiment, the main body 7 of the device is equipped with a positioner that cooperates with the central turntable 81. The positioner can specifically employ a conventional photoelectric sensor or a mechanical limit switch for rotational positioning. During the rotation of the central turntable 81, the positioner is triggered to determine the rotational position. The positioner is triggered when the four first opening and closing cylinders 83 move to the positions corresponding to the self-feeding device for injectable drugs, the cutting component 10, the bottle-breaking component 9, and the liquid-drawing component 11, respectively, to satisfy the subsequent actions. Alternatively, the rotation cycle and position of the central turntable 81 can be controlled by setting the duration of the first driver 82's operation after debugging, thereby determining the position of the central turntable 81.

[0056] Example 5: An automated injection drug extraction device, based on Example 4, such as... Figure 12 , 13As shown, the cutting assembly 10 includes a support base I 101 fixedly mounted on the main body 7. A second driver 102 is fixedly mounted on the support base I 101. The second driver 102 cooperates with a second opening and closing cylinder 103 and is used to drive the second opening and closing cylinder 103 to rotate. A floating cutting element 104 is provided on the opening and closing end of the second opening and closing cylinder 103. In this embodiment, the rotation center of the second driver 102 corresponds to the opening and closing symmetry center of the opening and closing end of the second opening and closing cylinder 103. Under the drive of the second driver 102, the rotation center of the cutting element 104 is located on the movement path of the opening and closing symmetry center of the V-shaped clamp 84. When the central turntable 81 rotates and drives the medicine bottle held by the V-shaped clamp 84 to move to a position corresponding to the rotation center of the second driver 102, the opening and closing end of the second opening and closing cylinder 103 partially closes, causing the cutting element 104 to adhere to the surface of the bottle neck. Under the drive of the second driver 102, the cutting element 104 rotates along the surface of the bottle neck, cutting a scratch. Specifically, in this embodiment, the cutting component 104 is a grinding wheel with high hardness, which can scratch the surface of the medicine bottle after contacting the bottle neck.

[0057] As a first optional floating setting scheme for the cutting component 104, a floating support rod 105 is fixedly provided on the opening and closing end of the second opening and closing cylinder 103, and the cutting component 104 is fixedly set on the floating support rod 105, thereby using the floating support rod 105 to achieve floating support for the cutting component 104.

[0058] Furthermore, the form of setting two cutting elements 104 respectively or setting only a single cutting element 104 can be selected. In this embodiment, the form of setting two cutting elements 104 is adopted. Floating support rods 105 are set at both opening and closing ends of the second opening and closing cylinder 103. The cutting elements 104 are coaxially fixed on the floating support rods 105. In actual use, the disc feeding mechanism 8 is used to transport the medicine bottle to a position coaxial with the opening and closing symmetrical center of the medicine bottle and the second opening and closing cylinder 103. The second opening and closing cylinder 103 drives the cutting elements 104 on the two opening and closing ends to open and close synchronously. After the cutting elements 104 are pressed on the mouth of the medicine bottle, the second driver 102 drives them to rotate. The cutting elements 104 move along the surface of the bottle neck, thereby scratching the bottle neck.

[0059] As a further specific implementation method, as an optional solution, such as Figure 14As shown, the floating support rod 105 includes a slidably sleeved bearing sleeve 1051 and an inner rod 1052. The bearing sleeve 1051 is fixedly connected to the cutting piece 104. The upper end of the inner rod 1052 is fixedly connected to the opening and closing end of the second opening and closing cylinder 103. A spring I 1053 is provided inside the bearing sleeve 1051. The two ends of the spring I 1053 are respectively fixed to the end of the inner rod 1052 and the baffle 1054 fixedly installed at the end of the bearing sleeve 1051, thereby realizing the floating support of the cutting piece 104 in the vertical direction and meeting the scratch requirements for different bottleneck heights. As another optional solution, such as Figure 15 As shown, the floating support rod 105 includes an elastic rod 1055 fixedly connected to the opening and closing end of the second opening and closing cylinder 103. A slidable sleeve 1056 is provided on the elastic rod 1055. The cutting component 104 is coaxially fixedly engaged with the sleeve 1056. The elastic rod 1055 can be a rubber rod, thus allowing the elastic bending of the elastic rod 1055 to adapt to the scratching requirements at different diameter positions when cutting bottle necks of different specifications. The sliding engagement between the sleeve 1056 and the elastic rod 1055 can achieve the scratching requirements at the bottle necks of different heights. Furthermore, the inner walls of the supporting sleeve 1051 and the sleeve 1056 are provided with keyways, and the outer walls of the elastic rod 1055 and the inner rod 1052 are provided with keys. The supporting sleeve 1051 and the inner rod 1052 are slidably engaged through the key and keyway, and the elastic rod 1055 and the sleeve 1056 are slidably engaged through the key and keyway, to prevent relative rotation of the cutting component 104 during cutting. The above two methods provide the cutting component 104 with a certain range of positional floating adjustment capability, enabling it to adapt to different bottleneck sizes and curvature shapes. When the cutting component 104 contacts the bottleneck, it tends to move towards the minimum point of the bottleneck. When rotating and cutting at the minimum point of the bottleneck, the path is more stable, achieving better fit and cutting.

[0060] Furthermore, as a further implementation, in this embodiment, a support arm 72 is provided on the main body 7 of the device between the cutting assembly 10 and the bottle-breaking assembly 9, or on the cutting assembly 10. In this embodiment, as... Figure 13 As shown, the support arm 72 is connected to the support base I101. Wiping bodies 73 are symmetrically arranged on the support arm 72, located on both sides of the movement path of the V-shaped clamping block 84 at the opening and closing symmetrical center of the first opening and closing cylinder 83. The wiping body 73 can be a rubber block, a sponge block, or a brush. When the medicine bottle passes through this position, the wiping body 73 can wipe and clean the neck area of ​​the medicine bottle to a certain extent, removing any glass fragments, dust, or other impurities, ensuring the purity and safety of the extracted medicine.

[0061] Example 6: An automated injection drug extraction device, differing from Example 5 in that, as a second optional scheme, the cutting element 104 is floating, such as... Figure 16 , 17As shown in Figure 18, in this embodiment, a floating support mechanism 106 is provided on the opening and closing end of the second opening and closing cylinder 103, and the floating support mechanism 106 is connected to the cutting piece 104. The floating support mechanism 106 includes a floating block 1061, and a support shell 1062 is provided on the opening and closing end of the second opening and closing cylinder 103. The floating block 1061 is movably disposed inside the support shell 1062, and the support shell 1062 provides a support connection base for the floating block 1061. A spring II 1063 is provided between the outer side of the floating block 1061 and the support shell 1062. The floating block 1061 can move horizontally relative to the opening and closing direction of the second opening and closing cylinder 103, so that the floating block 1061 has the ability to float in the horizontal direction. In addition, the floating block 1061 is provided with a vertically sliding blade holder 1064, and the cutting element 104 is located at the lower end of the blade holder 1064. Through the sliding connection between the blade holder 1064 and the floating block 1061, the cutting element 104 is provided with floating support in the vertical direction. This allows the cutting element 104 to adaptively cooperate with the bottleneck in both the vertical and horizontal directions.

[0062] Specifically, in this embodiment, the floating block 1061 has protrusions 1068 on both sides, and the support shell 1062 has horizontally symmetrically arranged slides that cooperate with the protrusions 1068, thereby guiding the floating block 1061 to slide. The floating block 1061 has a through hole, through which a blade holder 1064 passes. Both ends of the blade holder 1064 are threaded with anti-detachment caps 1067 to prevent it from coming out of the through hole during vertical sliding. The cutting piece 104 is fixed to the lower end of the blade holder 1064 by the anti-detachment caps 1067. Thus, the vertical floating is achieved by the blade holder 1064 sliding in the through hole. In addition, a flat cutting surface 1069 is provided between the blade holder 1064 and the through hole, thereby restricting rotation by using the cooperation of the flat cutting surface 1069 between the two, preventing relative rotation between the blade holder 1064 and the through hole, and thus preventing the cutting piece 104 from rotating and affecting the cutting effect.

[0063] During the process of fitting the cutting element 104 to the bottle neck, the position of the opening and closing end of the second opening and closing cylinder 103 is adjusted according to the bottle neck size during debugging to ensure that the cutting element 104 fits the bottle neck. A certain preload is applied in conjunction with the spring II 1063. When the cutting element 104 contacts the bottle neck, the floating block 1061 can float horizontally. The spring II 1063 provides a certain buffering effect on the floating block 1061 in the radial direction, preventing excessive preload from causing the cutting element 104 to directly press against the bottle neck and break. The preload applied to the cutting element 104 also maintains the cutting contact force between the cutting element 104 and the bottle neck. Furthermore, thanks to the floating connection of the blade holder 1064, which can slide vertically, the cutting element 104 can move along the curvature of the bottle neck to the point of minimum radius when it fits against the bottle neck. This allows for better contact with the outer wall of the bottle neck, limiting the cutting path, maintaining cutting stability, adapting to bottles of different specifications and shapes, improving cutting effect and adaptability, and effectively solving the problem of poor adaptability in existing devices.

[0064] As a further specific implementation, to achieve adjustment of the preload of spring II 1063, a knob I 1065 is threadedly connected to the support shell 1062, and the end of the knob I 1065 engages with spring II 1063. When it is necessary to adjust the elastic force of spring II 1063, the knob I 1065 is rotated, and the end of the knob I 1065 moves along its own axial direction, thereby compressing or relaxing spring II 1063, thereby changing the preload of spring II 1063 on floating block 1061, and adjusting the cutting force of the cutting element 104 connected to floating block 1061 on the bottleneck. Furthermore, to prevent the knob I 1065 from loosening and causing changes in the preload during long-term use after adjusting the preload, a set screw 1066 is provided on the support shell 1062 to engage with knob I 1065. The end of the set screw 1066 abuts against knob I 1065, thereby limiting the position of knob I 1065 after adjustment.

[0065] Example 7: An automated injection drug extraction device, based on Example 6, such as... Figure 19 As shown, the bottle-breaking assembly 9 includes a third driver 91 fixedly mounted on the main body 7. The third driver 91 cooperates with the support base II 92 and is used to drive the support base II 92 to rotate. A third opening and closing cylinder 93 is provided on the support base II 92. The opening and closing ends of the third opening and closing cylinder 93 are symmetrically provided with clamping arms 94. At least one clamping arm 94 has an adjustable pressure block 95 on its inner side.

[0066] As a further implementation method, such as Figure 20 , 21As shown, the inner side of the clamping arm 94 is detachably equipped with a replaceable clamping finger pad 941. The clamping finger pad 941 can be connected to the inner side of the end of the clamping arm 94 by bolts or plug-in. By quickly replacing the clamping finger pad 941 of different specifications, it can adapt to the shape or specification requirements of different bottle openings.

[0067] As an alternative implementation method, such as Figure 20 As shown, a stud is fixedly installed on the outside of the pressure block 95, and an elongated hole IV 96 is vertically provided on the clamping arm 94. The stud passes through the elongated hole IV 96 and is locked at the outer end by a nut, so that the position of the pressure block 95 can be adjusted during actual debugging to adapt to the need to break open medicine bottles of different sizes and specifications.

[0068] As another alternative implementation, such as Figure 21 , 22 As shown in Figure 23, the clamping arm 94 has a receiving groove II 942, and a bearing seat I 946 is fixedly installed in the receiving groove II 942. An adjusting screw 943 is rotatably connected to the bearing seat I 946. A slider 944 is slidably installed in the receiving groove II 942. The adjusting screw 943 is threadedly engaged with a threaded hole on the slider 944. A knob II 945 is fixedly installed on the adjusting screw 943. The pressure block 95 is fixedly connected to the slider 944. In this embodiment, rotating the knob II 945 drives the adjusting screw 943 to rotate. Then, with the cooperation of the threaded hole and the adjusting screw 943, the slider 944 slides vertically in the receiving groove II 942, realizing precise adjustment of the position of the pressure block 95. This is suitable for breaking bottle mouths of different heights and shapes, improving the versatility and adaptability of the device.

[0069] In this embodiment, the center of symmetry of the opening and closing of the third opening and closing cylinder 93 is located on the movement path of the center of symmetry of the opening and closing of the V-shaped clamping block 84 at the opening and closing end of the first opening and closing cylinder 83. Therefore, when the medicine bottle moves to the center of symmetry of the opening and closing of the third opening and closing cylinder 93, the third opening and closing cylinder 93 closes. Since most medicine bottle mouths have a tapered shape, such as ampoules, to simulate the biomimetic operation of manually breaking open the bottle mouth, a pressure block 95 is set on one of the clamping arms 94 in this embodiment. The pressure block 95 first contacts the bottle mouth, and then, during the continued closing process, the pressure block 95 can push the bottle mouth from one side first, simulating the biomimetic operation of manually breaking open the bottle, causing the medicine bottle to break from the scratch on the neck. Then, the clamping arm 94, in conjunction with the gripper finger pad 941, clamps the broken bottle mouth portion. A storage basket is set on one side of the main body 7. According to the position of the storage basket, the third driver 91 drives the support base II 92 to rotate within a certain angle range, the clamping arm 94 releases the bottle mouth, and the storage basket holds the broken bottle mouth.

[0070] Example 8: An automated injection drug extraction device, based on Example 7, as an optional solution, to better process the broken bottle neck portion, such as... Figure 19As shown, in the first optional embodiment, a bearing seat II 97 is fixedly installed on the main body 7 by bolts. A rotating shaft 98 is rotatably installed on the bearing seat II 97. The two ends of the rotating shaft 98 are respectively connected to the rotating end of the third driver 91 and the support seat II 92. Thus, when the third driver 91 is working, it can synchronously drive the support seat II 92 to rotate, thereby driving the opening and closing end of the third opening and closing cylinder 93 on the support seat II 92 to move accordingly. By controlling the rotation angle of the third driver 91, the rotating shaft 98 stops rotating when it reaches the limit position. The opening and closing end of the third opening and closing cylinder 93 expands, thereby moving the clamped bottle mouth into the storage basket located on one side of the main body 7.

[0071] As a second alternative implementation, such as Figure 23 , 24 As shown, a motor support 100 is fixedly mounted on the main body 7 of the equipment, and a third driver 91 is fixedly mounted on the motor support 100. The driving end of the third driver 91 is connected to a lead screw II 911. A telescopic guide tube assembly is sleeved on the lead screw II 911. The lower end of the telescopic guide tube assembly is connected to the motor support 100, and the upper end is connected to the support base II 92. A third opening and closing cylinder 93 is fixedly mounted on the support base II 92. A lead screw nut II 912 is fixedly mounted on the telescopic guide tube assembly. The lead screw nut II 912 is in transmission cooperation with the lead screw II 911. The third driver 91 can drive the lead screw II 911 to rotate and drive the lead screw nut II 912 to move axially.

[0072] Specifically, in this embodiment, the telescopic guide tube assembly includes an inner sleeve 913 fixedly mounted on the motor support 100. One end of the inner sleeve 913 is provided with a flange 914, which is bolted to the motor support 100. An outer sleeve 915 is connected to the support base II 92. The inner sleeve 913 and the outer sleeve 915 are nested and both are fitted over the lead screw II 911. The lead screw nut II 912 is fixedly mounted on the upper end of the outer sleeve 915. The inner sleeve 913 is provided with a guide groove 916, and the outer sleeve 915 is fixedly provided with a guide post IV 917 that cooperates with the guide groove 916.

[0073] When the third actuator 91 is activated, its drive end rotates the lead screw II 911. The transmission engagement between the lead screw II 911 and the lead screw nut II 912 drives the outer sleeve 915 to move axially, while the guide post IV 917 on the outer sleeve 915 moves along the guide groove 916 of the inner sleeve 913. The engagement of the guide groove 916 and the guide post IV 917 provides a guiding function, ensuring the stability of the movement of the outer sleeve 915, thereby driving the support seat II 92 and the third opening / closing cylinder 93 mounted on it to perform precise actions.

[0074] As a further optional embodiment, a branch pipe 918 is coaxially fixed at the upper end of the inner sleeve 913. The branch pipe 918 is located inside the outer sleeve 915, and a gap is left between the two. A bearing is provided at the upper end of the branch pipe 918. The bearing is used to achieve rotational engagement with the lead screw II 911 to support the upper part of the lead screw II 911 and improve the stability of the lead screw II 911.

[0075] Furthermore, in this embodiment, the guide chute 916 is an approximately L-shaped chute. The long section of the guide chute 916 is vertically arranged, and the short section of the guide chute 916 is located at the upper end of the long section and is arranged obliquely. During the breaking operation, the support seat II 92 is located in a lower position, and the disc feeding mechanism 8 drives the medicine bottle to move between the two clamping arms 94. At this time, the third opening and closing cylinder 93 closes, and the pressing block 95 gradually contacts the mouth of the medicine bottle to break it off and clamp the broken mouth of the medicine bottle. At this time, the inner sleeve 913 and the outer sleeve 915 are in a contracted state relative to each other in the length direction. At the same time, the guide post IV 917 is located at the lower end of the long groove section of the guide slide 916. When the lead screw II 911 rotates and drives the outer sleeve 915 to move upward, the guide post IV 917 moves upward with the outer sleeve 915. At the same time, the long groove section of the guide slide 916 limits the movement of the guide post IV 917. At the same time, the support seat II 92 moves upward, causing the bottle mouth to separate from the bottle along the axial direction, reducing the contact time between the disconnected bottle mouth and the bottle, and reducing the generation of debris. When the guide post IV 917 moves to the upper end of the long groove section of the guide slide 916, it enters the short groove section of the guide slide 916 during the continued upward movement. The outer sleeve 915 rotates under the drive of the lead screw II 911 and moves obliquely upward along the short groove section, causing the support seat II 92 to rotate and move upward relative to the axis of the outer sleeve 915, causing the bottle mouth to move to one side. Furthermore, a storage basket is set on one side of the main body 7 of the device. When the bottle mouth moves to the top of the storage basket, the third opening and closing cylinder 93 is released, allowing the bottle mouth to fall into the storage basket for collection, thus avoiding the problem of scattering.

[0076] As an optional solution, a semi-circular annular groove 99 coaxially arranged with the bearing seat II 97 is fixed on the main body of the equipment 7. The wire harness of the bottle-breaking assembly 9 is passed through the semi-circular annular groove 99. When the rotating shaft 98 rotates, the wire harness can move within the semi-circular annular groove 99 to avoid wear or bending of the wire harness.

[0077] Example 9: An automated injection drug extraction device, based on Example 8, such as... Figure 25 , 26 As shown, the liquid extraction assembly 11 includes a telescopic support rod 111 mounted on the main body 7 of the equipment. The telescopic end of the telescopic support rod 111 is provided with a support seat Ⅲ 112. The telescopic support rod 111 can drive the support seat Ⅲ 112 to move vertically. The support seat Ⅲ 112 is vertically provided with a liquid extraction needle 116. The liquid extraction needle 116 is connected to the liquid extraction pump 117 through a pipe.

[0078] Specifically, in this embodiment, the telescopic support rod 111 includes a fixed cylinder 1111 fixedly connected to the main body 7 of the device. An inner cylinder 1112 slidably passes through the open end of the fixed cylinder 1111. A fourth driver 113 is fixedly mounted on the main body 7. The rotating end of the fourth driver 113 is connected to a lead screw I 114. The lead screw I 114 is engaged with a lead screw nut I 115 located at the lower end of the inner cylinder 1112, thereby enabling the fourth driver 113 to drive the inner cylinder 1112 to move vertically relative to the fixed cylinder 1111. This, in turn, drives the support seat III 112 connected to the upper end of the fixed cylinder 1111 to move vertically, achieving the up-and-down movement of the extraction needle 116. This provides high transmission accuracy and stability, precisely controlling the insertion depth of the extraction needle 116 and preventing damage to the medicine bottle. The extraction pump 117 provides power for the extraction of the medicine. Driven by the support seat III 112, the extraction needle 116 can be accurately inserted into the medicine bottle, achieving efficient extraction of the medicine.

[0079] In addition, an L-shaped guide groove 1113 is provided on the fixed cylinder 1111, and a guide post Ⅲ 1114 is fixedly provided on the outer wall of the inner cylinder 1112. The guide post Ⅲ 1114 is slidably fitted in the L-shaped guide groove 1113. When the lead screw Ⅰ 114 rotates with the fourth driver 113 and drives the inner cylinder 1112 to move upward, the long arm section of the guide post Ⅲ 1114 slides vertically in the L-shaped guide groove 1113, which can play a guiding role. When it moves to the uppermost end, the guide post Ⅲ 1114 continues to move along the short arm section of the L-shaped guide groove 1113. The short arm section is inclined so that the upper support seat Ⅲ 112 can be deflected at a certain angle, so that the liquid extraction needle 116 in the non-liquid extraction state is separated from the movement path of the medicine bottle. Furthermore, a receiving cup is installed on one side of the main body 7 of the device to receive the liquid that remains on the suction needle 116 and drips when not in the suction state, so as to avoid the small amount of residual liquid dripping onto the central turntable 81 or the disc panel 86 and causing contamination.

[0080] As a further specific implementation, the main body 7 of the equipment is provided with a guide channel 71, which is located between the liquid extraction component 11 and the self-feeding device for injectable drugs. After the liquid extraction is completed, the first opening and closing cylinder 83 controls the V-shaped clamp 84 to release the medicine bottle, which automatically falls onto the guide channel 71 and is guided through the guide channel 71 to the outside of the main body 7 of the equipment. In actual use, a collection basket is set at the outlet of the guide channel 71 to receive the liquid.

[0081] As a further optional embodiment, the axis of the feed tube 32 of the self-feeding device for injectable drugs and the rotation center of the second driver 102 of the cutting assembly 10 are arranged perpendicular to the surface of the central turntable 81, which facilitates feeding and cutting. The bottle-breaking assembly 9 and the liquid-drawing assembly 11 are arranged in the vertical direction. The surface of the central turntable 81 has an inclination angle of 7° to 9° relative to the horizontal direction. The inclination angle of the central turntable 81 is used to tilt and transport the medicine bottle. Within this inclination angle range, it is convenient to insert the liquid-drawing needle 116 to draw liquid and prevent drug residue.

[0082] In actual operation, this embodiment includes the following workflow: 1. Feeding: The medicine bottle is output from the feeding channel 3 of the self-feeding device for injection drugs and enters between the V-shaped clamps 84. The V-shaped clamps 84 clamp the medicine bottle under the action of the first opening and closing cylinder 83.

[0083] 2. Scratching: The first driver 82 drives the central turntable 81 to rotate the medicine bottle to the cutting component 10. The second driver 102 drives the cutting component 104 to perform a scratching operation on the neck of the medicine bottle, forming a ring-shaped scratch or a specific shape such as a double arc symmetrical scratch or a multi-segment discontinuous scratch.

[0084] 3. Breaking the bottle opening: The bottle with the cut continues to rotate with the central turntable 81 to the bottle breaking assembly 9. The third opening and closing cylinder 93 drives the clamping arm 94 to close, and the pressing block 95 presses on the bottle opening. The bottle opening is broken off along the cut by the closing of the third opening and closing cylinder 93.

[0085] 4. Liquid extraction: After the medicine bottle is broken open, it continues to move to the liquid extraction assembly 11. The fourth driver 113 drives the support seat Ⅲ 112 to move vertically, so that the liquid extraction needle 116 is inserted into the medicine bottle. The liquid extraction pump 117 is started to extract the medicine and transport it through the pipeline to the designated container.

[0086] The automated injection drug extraction equipment provided in this embodiment achieves fully automated operation of the entire process from bottle feeding, conveying, cutting, and opening to liquid extraction through the rational layout and coordinated work of its components. This reduces manual intervention, lowers labor costs and human error, and improves work efficiency and production consistency. The precise coordination of each component ensures stable gripping and accurate positioning of the drug bottle in each process, enhancing operational accuracy and reliability. The liquid extraction component 11 achieves efficient extraction of the drug solution, reducing waste and improving the integrity and quality of the extracted solution. It effectively prevents drug contamination and impurity contamination, ensuring the purity and safety of the drug solution, while also facilitating equipment cleaning and maintenance.

[0087] Example 10 discloses an automated injection drug extraction device. Based on Example 9, in this example, the first driver 82, second driver 102, third driver 91, and fourth driver 113 can all be conventional servo motors or stepper motors. The first opening / closing cylinder 83, second opening / closing cylinder 103, and third opening / closing cylinder 93 can all be electric cylinders or pneumatic cylinders, utilizing electric or pneumatic drives for opening and closing. A conventional rotating slip ring is provided at the axis of the central turntable 81, supplying air or electricity to the first opening / closing cylinder 83 when it is rotating. The third driver 91 can also be an oscillating cylinder, using pneumatic power to achieve reciprocating rotation. This device is controlled by a conventional main controller such as a PLC. The main controller is connected to each moving component, controlling the actions of each component to achieve automated drug extraction.
