According to the medicine bottle clamping device, the clamping mechanism can form the clamping cavity for clamping the medicine container (such as a penicillin bottle, an ampoule bottle and the like), and the power mechanism 100 can drive the clamping mechanism to move, so that the clamping cavity can be switched between the clamping state and the releasing state. When the clamping cavity is in a clamping state, the medicine container can be clamped; when the clamping cavity is in a release state, the medicine container can be released so as to take out the medicine container, or the medicine container can be placed in the clamping cavity conveniently.

The clamping device comprises a plurality of clamping blocks, a first guide part is arranged on each clamping block, a plurality of second guide parts are arranged on each clamping seat, each first guide part and each second guide part respectively comprise a guide post and a guide groove, each guide post can be inserted into each guide groove and can slide along the extending direction of each guide groove, the distance between each guide groove and the center of each clamping seat is gradually reduced along the extending direction of each guide groove, and when the power mechanism 100 drives the plurality of clamping blocks to rotate around the corresponding rotation center, the sizes of clamping cavities formed between the plurality of clamping blocks can be changed under the matching guide action of the guide posts and the guide grooves, so that the clamping cavities can be switched between a clamping state and a releasing state. When the power mechanism 100 drives the clamping block to rotate, and the guide post slides in the guide groove along the direction that the distance between the guide groove and the center of the clamping seat is gradually reduced, the size of the clamping cavity can be gradually reduced, so that the clamping cavity can be gradually switched from a release state to a clamping state; when the power mechanism 100 drives the clamping block to reversely rotate, so that the guide post slides in the guide groove along the direction that the distance between the guide groove and the center of the clamping seat is gradually increased, the size of the clamping cavity can be gradually increased, and the clamping cavity can be gradually switched from the clamping state to the releasing state. Through the switching of the clamping cavity between the clamping state and the releasing state, the operations of taking, placing, clamping and the like of the medicine container are facilitated, and then the medicine dissolving and dispensing is facilitated.

As shown in fig. 2, a distance L1 of one end of the guide groove 23 from the center O of the holder is larger than a distance L2 of the other end of the guide groove 23 from the center O of the holder (L1 > L2), and the distance of the guide groove 23 from the center O of the holder gradually decreases in a direction from one end of the guide groove 23 toward the other end. The guide groove 23 is a variable diameter groove, and the difference between the distances of both ends thereof from the center O of the holder (the difference between L1 and L2) is a variable diameter difference, and the arc between one end and the other end of the guide groove 23 is referred to as a groove arc.

In some exemplary embodiments, the clamping seat comprises a socket 8 and a rotating disc, and a plurality of clamping blocks are rotatably mounted to the socket 8 and cooperate with the socket 8 to form a clamping cavity 25; the rotating disc is rotationally connected with the bearing seat 8, and the second guide part is arranged on the rotating disc; the power mechanism 100 is configured to rotate the clamping blocks by driving the rotating disk to rotate.

In the medicine bottle clamping device, a clamping seat of a clamping mechanism can comprise a bearing seat 8 and a rotating disc, the bearing seat 8 can be used for installing a plurality of clamping blocks (such as clamping blocks 4-7) and the rotating disc, and the clamping blocks 4-7 and the rotating disc can be in rotary connection with the bearing seat 8; the clamping blocks 4-7 can be sequentially arranged along the circumferential direction of the bearing seat 8 and are matched with the bearing seat 8 to form a clamping cavity 25, and the bearing seat 8 can form the bottom wall of the clamping cavity 25; the second guiding part can be arranged on the rotating disc, so that connection can be realized between the clamping blocks 4-7 and the rotating disc through the cooperation of the guiding posts and the guiding grooves, and when the power mechanism 100 can drive the rotating disc to rotate, the rotating disc can drive the clamping blocks 4-7 to rotate through the cooperation of the guiding posts and the guiding grooves, and the clamping cavity 25 can be switched between a clamping state and a releasing state.

In some exemplary embodiments, the rotating discs include a first rotating disc 2 and a second rotating disc 3 stacked, the first rotating disc 2 and the second rotating disc 3 are fixedly connected and are provided with second guide portions, and the first guide portions of the plurality of clamping blocks are alternately matched with the second guide portions of the first rotating disc 2 and the second guide portions of the second rotating disc 3.

In the rotating disc, the first rotating disc 2 and the second rotating disc 3 can be stacked and fixedly connected, and the first rotating disc 2 and the second rotating disc 3 are respectively provided with a second guiding part, so that the first guiding parts of the clamping blocks can be alternately matched with the second guiding parts on the first rotating disc 2 and the second guiding parts on the second rotating disc 3, namely: among the plurality of clamp blocks which are sequentially arranged along the circumferential direction of the bearing seat 8, the guide post on one clamp block can be matched and guided with the second guide part on the first rotating disc 2, and the first guide part on the adjacent other clamp block can be matched and guided with the second guide part on the second rotating disc 3.

In the example shown in fig. 1, four clamp blocks 4-7 are rotatably mounted on the socket 8 by four first rotating shafts 11-14, respectively, and the four clamp blocks 4-7 are uniformly arranged along the circumferential direction of the socket 8. Two rotating discs are arranged in cooperation with the four clamping blocks 4-7: the first rotating disc 2 and the second rotating disc 3, the first rotating disc 2 is provided with two guide grooves 23 and 24, the second rotating disc 3 is also provided with two guide grooves (not shown), and if the first rotating disc 2 rotates 90 degrees and the second rotating disc does not rotate, the two guide grooves 23 and 24 on the first rotating disc 2 are overlapped with the two guide grooves on the second rotating disc 3.

The clamping blocks 4, 6, 5 and 7 are arranged along the circumference of the bearing seat 8 in sequence, the guide posts (including the second rotating shaft 15 and the second bearing 19) on the clamping blocks 4 can be matched and guided with the guide grooves 23 on the first rotating disc 2, the guide posts (not shown) on the adjacent clamping blocks 6 can be matched and guided with the guide grooves (not shown) on the second rotating disc 3, the guide posts (including the second rotating shaft 16 and the second bearing 20) on the other clamping blocks 5 adjacent to the clamping blocks 6 can be matched and guided with the guide grooves 24 on the first rotating disc 2, and the guide posts (not shown) on the other clamping blocks 7 adjacent to the clamping blocks 5 can be matched and guided with the guide grooves (not shown) on the second rotating disc 3.

Compared with the arrangement of the guide groove on the first rotating disc 2 or the second rotating disc 3, the guide groove is arranged on the first rotating disc 2 and the second rotating disc 3, the extension length of the guide groove along the circumferential direction of the rotating disc can be increased, and therefore when the radius difference between two ends of the guide groove is kept unchanged, the radius of the clamping cavity is changed by the same amount, the sliding distance of the guide column of the clamping block along the guide groove is longer, namely the rotating angle of the clamping block is larger, and the clamping force and the adjusting precision of the clamping cavity are improved.

In some exemplary embodiments, the second guide portion includes a guide groove, and an angle α of a line between both ends of the guide groove and a center of the holder is set to: 360 DEG/N < alpha < 2X 360 DEG/N, wherein N is the number of clamping blocks.

In the example shown in fig. 1, guide grooves are provided on both the first rotating disk 2 and the second rotating disk 3, and for either guide groove, for example: the angle α of the line between the two ends of the guide groove 23 on the first rotating disc 2 and the center O of the holder is set as: 360 DEG/N < alpha < 2X 360 DEG/N, namely 90 DEG < alpha < 180 DEG (N is the number of clamping blocks 4). So set up for a plurality of guide slots that equals the guide post quantity on a plurality of clamp splice can be respectively formed on first rolling disc 2 and second rolling disc 3, and make the guide slot along the extension length of rolling disc circumference longer.

In some exemplary embodiments, the center of rotation of the rotating disc coincides with the center of the clamping seat, and the centers of rotation of the plurality of clamping blocks are equidistant from the center of the clamping seat.

In the example shown in fig. 1, the rotational centers (rotational axes) of the clamp blocks 4-7 are equidistant from the center of the clamp holder such that the central axes of the first rotary shafts 11-14 that rotationally connect the clamp blocks 4-7 with the socket 8 are located on the same circle (first circle); the centers (center lines) of the first rotating disc 2 and the second rotating disc 3 can be coincident with the center of the clamping seat, guide grooves with the same size are formed in the first rotating disc 2 and the second rotating disc 3, each guide groove is matched with the corresponding guide post of one clamping block, the distances between the centers of the guide posts arranged on the clamping blocks 4-7 and the center of the clamping seat are always kept equal, and the centers of the guide posts arranged on the clamping blocks 4-7 can be dynamically located on the same circle (second circle), and the center of the second circle is identical with that of the first circle.

By means of the structural design, when the clamping cavity 25 is in a clamping state, a releasing state and is changed between the clamping state and the releasing state, the center of the clamping cavity 25 is kept unchanged, the center of a clamped medicine containing container is facilitated to be fixed, the medicine containing container is clamped to an accurate position, and operations such as medicine suction and the like during subsequent automatic medicine preparation are greatly improved.

In some exemplary embodiments, the first guide portion includes a guide post, and the guide post is offset from a center of rotation of the clamp block.

In the example shown in fig. 1, the center (central axis) of the guide post (including the second rotation shaft 15 and the second rotation shaft 19) on the clamp block 4 may be offset from the rotation center of the clamp block 4 (i.e., the central axis of the first rotation shaft 12), the guide post (including the second rotation shaft 16 and the second rotation shaft 20) on the clamp block 5 may be offset from the rotation center of the clamp block 5 (i.e., the central axis of the first rotation shaft 14), the center (central axis) of the guide post on the clamp block 6 may be offset from the rotation center of the clamp block 6 (i.e., the central axis of the first rotation shaft 13), and the center (central axis) of the guide post on the clamp block 7 may be offset from the rotation center of the clamp block 7 (i.e., the central axis of the first rotation shaft 11), so that when the power mechanism 100 drives the first rotation disc 2 and the second rotation disc 3 to rotate, the clamp blocks 4-7 can be driven to rotate around the respective rotation centers by the cooperation between the guide post and the guide grooves, thereby realizing the switching of the states of the clamp cavity 25.

In some exemplary embodiments, the guide groove is spaced from the center of the clamping block by a distance greater than the distance of the center of rotation of the clamping block from the center of the clamping block.

In the example shown in fig. 1, the two guide grooves 23-24 on the first rotatable plate 2 and the two guide grooves on the second rotatable plate 3 are located at a distance from the center of the holder that is greater than the distance from the center of rotation of the clamp block 4-7 to the center of the holder, so that the maximum size of the clamp chamber 25 enclosed by the clamp block 4-7 can be determined by the center of rotation of the clamp block 4-7, and thus the maximum size of the medicine container that can be clamped in the clamp chamber 25 can be determined by the center of rotation of the clamp block 4-7.

In some exemplary embodiments, the clamping seat further comprises a transmission disc 9, the transmission disc 9 is rotationally connected with the bearing seat 8, and the rotation disc is fixedly connected with the transmission disc 9; the power mechanism 100 is connected to the driving disk 9 and is configured to drive the driving disk 9 to rotate.

In the example shown in fig. 1, the transmission disc 9 is fixed to the first rotary disc 2 and the second rotary disc 3, and the transmission disc 9 is rotatably connected to the receiving seat 8. Wherein the centers (center lines) of the socket 8, the driving disc 9, the first rotating disc 2 and the second rotating disc 3 may coincide to form the center of the clamping seat.

The driving disc 9 can be connected with the power mechanism 100, the power mechanism 100 can drive the driving disc 9 to rotate, and then drive the first rotating disc 2 and the second rotating disc 3 to rotate, and then the first rotating disc 2 and the second rotating disc 3 drive the corresponding clamping blocks 4-7 to rotate, so that the clamping cavity 25 is switched between a clamping state and a releasing state.

The power mechanism 100 indirectly drives the clamping blocks 4-7 to rotate by driving the transmission disc 9 to rotate, and compared with the scheme that the power mechanism 100 directly drives the clamping blocks 4-7 to rotate, the power mechanism 100 indirectly drives the clamping blocks 4-7 to rotate through the transmission disc, thereby being beneficial to simplifying the power mechanism 100.

In some exemplary embodiments, the socket 8 is disposed on one side of the plurality of clamping blocks, the rotating disc is disposed on one side of the plurality of clamping blocks away from the socket 8, and the rotating disc is provided with a central hole to form an opening of the clamping cavity 25; the driving disk 9 is arranged between the bearing seat 8 and the rotating disk, and the driving disk 9 is provided with avoiding holes for avoiding a plurality of clamping blocks.

In the example shown in fig. 1, the socket 8 is disposed at the lower side of the clamp block 4-7, the first rotating disc 2, the second rotating disc 3 and the clamp block 4-7 are disposed at the same side of the socket 8, the first rotating disc 2 is mounted in association with the clamp block 4-5, the second rotating disc 3 is mounted in association with the clamp block 6-7, the driving disc 9 is disposed between the socket 8 and the rotating disc, and the driving disc 9 is provided with a avoiding hole for avoiding the clamp block 4-7, which may be a central hole disposed at the center of the driving disc 9, so that the driving disc 9 may be sleeved outside the clamp block 4-7, so that the clamp block 4-7 and the socket 8 are matched to enclose the clamp cavity 25. The first and second rotatable disks 2, 3 are each provided with a central aperture to form an opening for the holding chamber 25 through which the medicament container can be retrieved.

In some exemplary embodiments, the inner side surface of the clamping block 4-7 is a clamping surface for clamping the medicine container, the guide posts on the clamping block 4-7 are matched with the guide grooves of the first rotating disk 2 and the second rotating disk 3, the first rotating disk 2 and the second rotating disk 3 rotate to drive the clamping block 4-7 to rotate, and one end, far from the rotation center, of the clamping block 4-7 moves towards the direction close to the center of the bearing seat 8, so that the inner side surface of the clamping block 4-7 clamps the medicine container. When the first rotating disc 2 and the second rotating disc 3 rotate reversely, the clamping blocks 4-7 are driven to rotate reversely, and one end, far away from the rotation center, of the clamping blocks 4-7 moves in a direction far away from the center of the bearing seat 8. When the guide posts slide to the end of the corresponding guide grooves far from the center of the bearing seat 8, the size of the space formed by the inner side surfaces of the clamping blocks 4-7 determines the maximum outer diameter of the container capable of clamping the medicine. When the guide posts slide to the end of the corresponding guide grooves near the center of the receiving seat 8, the size of the space formed by the inner side surfaces of the plurality of clamping blocks 4-7 determines the minimum outer diameter of the container capable of clamping the medicine. In the process that the guide posts slide between one end far from the center of the bearing seat 8 and one end close to the center of the bearing seat 8 in the corresponding guide grooves, the diameter variation of the clamping points on the inner sides of the clamping blocks 4-7 is equal to or in direct proportion to the diameter variation of the guide grooves, and the diameter variation of the guide grooves determines the distance between the maximum clamping position and the minimum clamping position of the clamping blocks 4-7, namely the difference between the upper limit and the lower limit of the size of the clampable medicine containing container, which is called the bottle diameter floating quantity of the medicine containing container.

If the difference of bottle diameters between the large and small medicine containers to be clamped exceeds the variable diameter floating amount of the clamping blocks 4-7 of one clamping mechanism, a plurality of clamping mechanisms with different bottle diameter floating amounts are needed. Under the condition that the working principle is unchanged, the bottle diameter floating quantity can be achieved through adjustment of a plurality of sizes, and the method comprises the following steps: the difference between the distance of the center of rotation of the clamp block 4-7 from the center of the socket 8 and the distance of the guide post from the center of the socket 8 is increased or decreased, and/or the difference in diameter between both ends of the guide groove is increased or decreased, and/or the distance (radius of the first circle) between the center of rotation of the clamp block 4-7 and the center of the socket 8 is increased or decreased.

The first rotation shaft of the clamping block is positioned on the circumference of a first circle, and the radius of the first circle determines the maximum bottle diameter of the medicine container which can be clamped by the clamping mechanism. The smallest diameter of the grippable medicine container is obtained by subtracting the floating amount of the bottle diameter from the largest bottle diameter.

In some exemplary embodiments, the medicine bottle holding device further includes a base 1 and a damping device 200, the socket 8 is rotatably mounted to the base 1, and the damping device 200 is disposed between the socket 8 and the base 1 such that the socket 8 can be fixed with respect to the base 1 by a damping force of the damping device 200 or the socket 8 can be rotated with respect to the base 1 against the damping force of the damping device 200 when the power mechanism 100 drives the rotation plate to rotate.

In the medicine bottle holding device, the base 1 may be used to mount, support the holding mechanism, the power mechanism 100, and the damping device 200; the receiving seat 8 of the clamping mechanism is rotatably mounted to the base 1 so that the clamping mechanism as a whole can rotate relative to the base 1; the damping device 200 is arranged between the bearing seat 8 and the base 1, so that when the power mechanism 100 drives the first rotating disc 2 and the second rotating disc 3 to rotate by driving the transmission disc 9 to rotate, the bearing seat 8 can be fixed relative to the base 1 under the damping force of the damping device 200, and at the moment, the clamping blocks 4-7 can rotate relative to the bearing seat 8, so that the clamping cavity 25 can be switched between a clamping state and a releasing state to clamp or release the medicine container; or, when the clamping cavity 25 is in a clamping state and clamps the medicine container, the medicine container prevents the clamping blocks 4-7 from continuing to rotate so as to further reduce the size of the clamping cavity 25, so that the first rotating disc 2, the second rotating disc 3 and the transmission disc 9 cannot continue to move relative to the bearing seat 8 and then become fixed relative to the bearing seat 8, at the moment, the clamping cavity 25 is kept in the clamping state, the whole clamping mechanism is relatively fixed, the power mechanism 100 continues to drive the whole clamping mechanism to move, the damping force of the damping device 200 is overcome, the whole clamping mechanism rotates relative to the base 1, and the clamped medicine container is further driven to rotate, so that the contents in the medicine container are dissolved, mixed and the like, and the medicine dissolving and dispensing efficiency is improved.

In the process of loosening the clamped medicine container, the power mechanism 100 drives the transmission disc 9 to reversely move relative to the bearing seat 8, and the guide grooves of the first rotating disc 2 and the second rotating disc 3 drive the clamping blocks 4-7 to reversely rotate through the guide posts, so that the clamping cavity 25 is changed from the clamping state to the releasing state, the clamped medicine container is loosened, and the medicine container is convenient to take and place.

The power mechanism 100 drives the clamping mechanism to move, so that the clamping mechanism can be used for clamping or releasing the medicine container on one hand, and can be used for continuously driving the medicine container to move after clamping the medicine container so as to promote the dissolution, mixing and the like of the content in the medicine container. In the process of clamping or releasing the medicine container, the damping device 200 can prevent the bearing seat 8 from rotating relative to the base 1, the clamping force of the clamping mechanism on the medicine container is related to the damping force of the damping device 200 on the bearing seat 8, and the larger the damping force is, the larger the clamping force of the clamping mechanism is required to resist the damping force to drive the clamping blocks 4-7, and the larger the clamping force of the clamping mechanism is reflected; secondly, the clamping force of the clamping mechanism is related to the diameter variation at two ends of a guide groove (diameter variation groove) in the clamping mechanism, and under the condition that the damping force is fixed, the smaller the diameter variation, the longer the groove arc is when the guide groove pushes the clamping block 4-7 to move inwards to clamp the medicine containing container through the guide post, the larger the component force of the force applied by the clamping block 4-7 to the medicine containing container in the direction towards the center of the clamping cavity 25 is, and the larger the corresponding clamping force is. According to the embodiment of the application, the clamping blocks 4-7 are driven to move in the clamping mechanism in the mode of the reducing grooves, under the condition that the damping force provided by the damping device 200 is the same, the clamping force of the clamping mechanism to the medicine container is multiplied by adopting the principle of geometrical component force, so that the friction force generated between a puncture outfit (see below in the detailed description) and a bottle stopper of the medicine container in the medicine dispensing process of the medicine dissolving and dispensing device is sufficiently resisted, the medicine container can be always fixed in the medicine bottle clamping device in the medicine dispensing process, and the stability and efficiency of the medicine dissolving and dispensing process are improved.

The guide groove (reducing groove) of the embodiment of the present application is inclined radially due to the reducing relative to the center of the clamping seat, so that a tangential component force rotating around the center of the clamping seat and a lateral component force pressing the clamping block 4-7 toward the center of the clamping seat are applied to the clamping block 4-7 in the process of driving the clamping block 4-7 to rotate, and the effect is that the former (tangential component force) rotates the clamping block 4-7 against the damping force of the damping device 200, while the latter (lateral component force) can clamp the medicine container. There is a fixed proportional relationship between the former and latter components. The embodiment of the application amplifies the damping force by utilizing the fixed proportion, thereby generating clamping force which is multiple times of the damping force on the medicine container. The magnitude of the ratio is related to the diameter variation of the guide groove, and the smaller the diameter variation is, the larger the ratio is; meanwhile, the longer the slot arc is, the larger the proportion is, and the larger the clamping force on the medicine container is. In the embodiment of the application, the guide grooves are respectively formed in the first rotating disc 2 and the second rotating disc 3, and the included angle alpha of the connecting line between the two ends of the guide grooves and the center of the clamping seat is set to be 360 degrees/N < alpha < 2 multiplied by 360 degrees/N, so that the groove arc of the guide grooves grows.

In the specific example shown in fig. 1, the socket 8 is a socket and is rotatably mounted on the base 1. A first bearing 10 is arranged between the bearing seat 8 and the base 1, an outer ring of the first bearing 10 can be fixed with one of the base 1 and the bearing seat 8, and an inner ring of the first bearing 10 can be fixed with the other of the base 1 and the bearing seat 8.

In some exemplary embodiments, the damping device 200 may include a friction block fixed to one of the base 1 and the socket 8, and the other of the base 1 and the socket 8 is in contact with the friction block. The friction block can provide friction force to prevent the bearing seat 8 from rotating relative to the base 1, so that the power mechanism 100 can drive the clamping blocks 4-7 to rotate to clamp the medicine container.

Alternatively, the damping device 200 may comprise a damping bearing comprising a bearing outer race fixed to one of the base 1 and the socket 8 and a bearing inner race fixed to the other of the base 1 and the socket 8. The bearing outer ring and the bearing inner ring of the damping bearing are respectively fixed on the base 1 and the bearing seat 8, damping force exists between the bearing inner ring and the bearing outer ring to prevent the bearing inner ring and the bearing outer ring from rotating relatively so as to prevent the bearing seat 8 from rotating relative to the base 1. Such as: instead of the normal first bearing 10, a damping bearing may be used, and the damping of the damping bearing is used to apply resistance to the rotation of the socket 8.

Alternatively, the damping device 200 comprises a damper comprising a telescopic damping rod, the damper being mounted on one of the base 1 and the socket 8, the damping rod being connected to the other of the base 1 and the socket 8. In this damper, the damping rod generates a damping force when it expands and contracts to prevent the socket 8 from rotating relative to the base 1.

In some exemplary embodiments, the power mechanism 100 is a rotary power mechanism, and may include a motor coupled to the drive disk 9 of the clamping mechanism to rotate the drive disk 9. The motor may be a motor with a locking function or the motor may be equipped with a lockable transmission.

The motor of the power mechanism 100 has a locking function so that after the motor stops working, the clamping mechanism connected with the motor can be kept fixed, the clamping cavity 25 is kept in a clamping state, and the medicine container is clamped. Specifically, the motor can have a power-on self-locking function, and when the motor is stopped, the driving circuit continuously outputs a constant current to enable the motor to be locked by the shaft of the motor, so that the clamping mechanism is kept in a clamping state; or the motor has a power-off self-locking function, a band-type brake device (brake device) is additionally arranged at the tail part of the motor, and when the motor is electrified, the band-type brake device is separated from an output shaft of the motor, the motor normally operates, and when the motor is powered off, a brake tightly holds the output shaft of the motor, so that the output shaft of the motor is locked; or, the output shaft end of the motor is provided with a lockable transmission mechanism such as a gear box, and when the motor is powered off, the output shaft of the motor is locked by utilizing friction force between gears in the gear box.

The medicine bottle clamping device of the embodiment of the application has the following working process:

in the process of clamping the medicine container, firstly, the medicine container is placed on the bearing seat 8 and placed in the clamping cavity 25, then the power mechanism 100 is started to enable the motor 100 to be electrified and rotated, the transmission disc 9 and the first rotating disc 2 and the second rotating disc 3 fixed with the transmission disc are driven to rotate relative to the bearing seat 8 towards a first direction, the first rotating disc 2 and the second rotating disc 3 drive the clamping blocks 4-7 to rotate, and the bearing seat 8 cannot be immediately driven to rotate due to the fact that the damping force is applied to the bearing seat 8 by the damping device 200, so that the clamping blocks 4-7 rotate relative to the bearing seat 8 until the clamping blocks 4-7 touch the outer wall of the medicine container, at the moment, the clamping blocks 4-7 cannot continue to rotate inwards, at the moment, the clamping cavity 25 is changed from a release state to a clamping state, and the medicine container is clamped.

The power mechanism 100 continues to drive the driving disc 9 to move towards the first direction, when the rotation driving force of the driving disc 9 is greater than the resistance applied on the bearing seat 8 by the damping device 200, the clamping blocks 4-7 can overcome the resistance of the damping device 200 to drive the bearing seat 8 to rotate, and at the moment, the driving disc 9, the first rotating disc 2, the second rotating disc 3, the clamping blocks 4-7 and the bearing seat 8 are kept relatively fixed and drive the medicine containing container to rotate, so that the dissolution and the mixing of the contents in the medicine containing container are realized. The medicine bottle clamping device can clamp the medicine container and simultaneously drive the medicine container to rotate.

When the motor of the power mechanism 100 is powered off, the clamping mechanism stops rotating, and the clamping blocks 4-7 keep the original clamping state by the locking function of the motor so as to keep the medicine container in the clamping state.

In the process of releasing the medicine container, the power mechanism 100 is started to enable the motor to reversely rotate, the transmission disc 9 and the first rotating disc 2 and the second rotating disc 3 fixed with the transmission disc are driven to rotate towards a second direction (opposite to the first direction) relative to the bearing seat 8, and the first rotating disc 2 and the second rotating disc 3 drive the clamping blocks 4-7 to reversely rotate, so that the clamping cavity 25 is changed from the clamping state to the releasing state, and the clamped medicine container is released, so that the medicine container can be taken out.

The embodiment of the application also provides a medicine dissolving and dispensing device, including medicine bottle clamping device and at least one medicine dissolving and dispensing channel (not shown) that any of the above embodiments provided, medicine bottle clamping device sets up to the centre gripping and holds the medicine container, dissolves the medicine dispensing channel and includes two puncture outfits and connects the elasticity infusion hose of two puncture outfits, and two puncture outfits set up to pierce two medicine containers respectively.

In the medicine dissolving and dispensing device, the medicine bottle clamping device can be used for clamping the medicine containing containers, two puncture devices of the medicine dissolving and dispensing channel can respectively puncture the two medicine containing containers, so that the two medicine containing containers are communicated through the medicine dissolving and dispensing channel, and contents in the two medicine containing containers can flow and mix with each other by extruding the elastic transfusion hose (for example, extruding the elastic transfusion hose by using a peristaltic pump), so as to realize medicine dissolving and dispensing. Wherein, the two medicine containers can be clamped by the medicine bottle clamping device provided by any embodiment, namely the solution dispenser can comprise the medicine bottle clamping device provided by any embodiment; alternatively, one container may be held by a vial holder provided by any of the embodiments described above, and another container may be held by another holder, i.e. the solution dispenser may comprise a vial holder provided by any of the embodiments described above.

In summary, in the medicine bottle clamping device of the embodiment of the present application, the clamping blocks 4-7 clamp the medicine container and drive the medicine container to rotate are all driven by the power mechanism 100 through the driving disc 9. Compared with the power mechanism 100 which directly pushes the clamping block to rotate, the power mechanism 100 pushes the clamping block 4-7 to rotate through the transmission disc 9 and the guide grooves on the first rotating disc 2 and the second rotating disc 3, and the damping force of the anti-damping device 200 is multiplied by adopting the geometrical component force principle, so that the clamping force of the clamping block 4-7 to the medicine container is multiplied, and the friction force generated when the puncture device pierces the bottle stopper of the medicine container in the medicine dispensing process of the medicine dissolving and dispensing device is enough to be resisted, so that the medicine container can be always fixed in the medicine bottle clamping device in the medicine dispensing process, and the stability and efficiency of a medicine dissolving and dispensing program are improved.
