The granule preparation metering mechanism is used in conjunction with a medicine bottle to form a medicine bottle assembly for containing granule preparations. During dispensing, the medicine bottle assembly is installed on the granule preparation dispensing and dispensing mechanism, and the granule preparation dispensing and dispensing mechanism drives the granule preparation metering mechanism to realize automatic metering and discharging of the granule preparations in the medicine bottle assembly.

[0003] For example, the Chinese utility model patent with application number CN202222283110.6 provides a quantitative filling device for a granular preparation, including a dispensing mechanism for quantitatively filling the granular preparation and a driving mechanism for driving the dispensing mechanism to operate. The mouth of a dispensing bottle containing the granular preparation is inverted and installed on the top of the dispensing mechanism.

[0004] The granule preparation metering mechanism (i.e., the dispensing mechanism) is provided with a first dispensing plate and a second dispensing plate. When working, the granule preparation dispensing and dispensing mechanism (i.e., the driving mechanism) drives the first dispensing plate and the second dispensing plate to move relative to each other to determine the dispensing quantity, and drives the first dispensing plate and the second dispensing plate to move synchronously to transfer the granule preparation. However, the granule preparation dispensing and dispensing mechanism of the existing granule preparation dispensing device is generally equipped with two motors, and the movement of the first dispensing plate and the second dispensing plate is controlled by the two motors respectively. The equipment cost is high, the control process is cumbersome, and the control system is complicated.

DETAILED DESCRIPTION

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0051] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0052] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0053] like Figures 1 to 25 As shown, the embodiment of the present invention introduces a granule preparation dispensing device, which includes a medicine bottle assembly 100 for containing granule preparations and a granule preparation dispensing and dispensing mechanism 200. The medicine bottle assembly 100 includes a medicine bottle 2 and a granule preparation metering mechanism 1 for quantitatively dispensing the granule preparations. The medicine bottle assembly 100 is installed on the granule preparation dispensing and dispensing mechanism 200, and the granule preparation dispensing and dispensing mechanism is used to drive the granule preparation metering mechanism 1 to operate. The granule preparation dispensing and dispensing mechanism 200 drives the granule preparation metering mechanism 1 to realize automatic metering and discharging of the granule preparations in the medicine bottle assembly 100.

[0054] The granule preparation metering mechanism 1 includes a metering body 11, a metering cavity is arranged in the metering body 11, a feed port 1112 is arranged on the top wall of the metering cavity, a discharge port 1121 is arranged on the bottom wall of the metering cavity, and an adjustment plate that can slide along the cavity wall of the metering cavity is arranged in the metering cavity. In the vertical direction, the feed port 1112 and the discharge port 1121 are offset from each other. Specifically, the feed port 1112 and the discharge port 1121 are arranged along the sliding direction of the adjustment plate, and the projections of the feed port 1112 and the discharge port 1121 in the same horizontal plane do not overlap.

[0055] The upper end surface of the adjusting plate is fitted and slidably matched with the top wall of the metering cavity, the lower end surface of the adjusting plate is fitted and slidably matched with the bottom wall of the metering cavity, and along the sliding direction of the adjusting plate, the left and right side surfaces of the adjusting plate are respectively fitted and slidably matched with the left and right side walls of the metering cavity. Specifically, the adjusting plate slides along the length direction of the metering cavity. The adjusting plate includes a first adjusting plate 12 and a second adjusting plate 13 arranged along the length direction of the metering cavity, and the opposite sides of the first adjusting plate 12 and the second adjusting plate 13 can be fitted with each other.

[0056] The top wall of the dispensing chamber is provided with an upwardly extending mounting opening 1111, which is used to dock with the bottle mouth of the medicine bottle 2 containing the granular preparation, the bottle mouth is installed at the mounting opening 1111, and the feed port 1112 is arranged in the surrounding range of the mounting opening 1111. After the granular preparation metering mechanism 1 is installed on the bottle mouth of the medicine bottle 2, the medicine bottle assembly 100 is inverted as a whole and installed on the granular preparation dispensing mechanism 200. In the process of dispensing the granular preparation, the first dispensing plate 12 and the second dispensing plate 13 are separated from each other to form a cavity for temporarily storing the granular preparation, and the cavity can allow the granular preparation in the medicine bottle assembly 100 to fall into the dispensing chamber. The cavity is connected to either the feed port 1112 or the discharge port 1121. Specifically, when the cavity is connected to the feed port 1112, the granular preparation in the medicine bottle assembly 100 falls into the cavity between the first adjustment plate 12 and the second adjustment plate 13, and fills the cavity to achieve quantitative measurement of the granular preparation. When the cavity is connected to the discharge port 1121, the granular preparation in the cavity is output. Thus, quantitative output of the granular preparation in the medicine bottle assembly 100 is achieved.

[0057] Embodiment 1

[0058] The existing granule preparation metering mechanism 1 generally uses two power sources to drive the first adjusting plate 12 and the second adjusting plate 13 respectively, which increases the cost of the granule preparation metering mechanism 1. Moreover, in the process of adjusting the granule preparation, it is necessary to control the two power sources to cooperate with each other, resulting in cumbersome control process of the granule preparation and complex control system.

[0059] In order to solve the above technical problems, in the embodiment of the present invention, a granule preparation dispensing and dispensing mechanism 200 is introduced, such as Figures 1 to 13 As shown, the entire dispensing process can be completed by driving with one power source, which simplifies the control system and control process of the granule preparation dispensing device, reduces the operating difficulty and error rate of the device, and at the same time, reduces the cost.

[0060] The granule preparation dispensing and dispensing mechanism 200 includes a first connecting rod 3241 and a second connecting rod 3242, which are respectively used to connect with the first dispensing plate 12 and the second dispensing plate 13 of the granule preparation metering mechanism 1, and the granule preparation dispensing and dispensing mechanism 200 also includes a linear transmission module, the output end of the linear transmission module is fixedly connected with the second connecting rod 3242, and the output end of the linear transmission module is connected with the first connecting rod 3241 through a clutch structure. Thus, in the process of the linear transmission module driving the second connecting rod 3242 to move, the first connecting rod 3241 can be selectively driven to move synchronously through the clutch structure, or only the second connecting rod 3242 can be driven to move, which can be suitable for driving the connection between the first dispensing plate 12 and the second dispensing plate 13 of the granule preparation metering mechanism 1.

[0061] like Figure 4 , Figure 5 , Figures 7 to 9 As shown, the clutch structure includes a linkage assembly 323 and a limiting structure. The linkage assembly 323 is installed on the output end of the linear transmission module, and the first connecting rod 3241 is connected to the linkage assembly 323. The output end of the linear transmission module drives the first connecting rod 3241 to move through the static friction provided by the linkage assembly 323. The limiting structure is used to limit the first connecting rod 3241, and / or the limiting structure is used to limit the first adjustment plate 12, so that the linear transmission module drives the second adjustment plate 13 to move separately through the second connecting rod 3242.

[0062] Specifically, the linkage assembly 323 includes a first friction block 3231 and a second friction block 3232. The first friction block 3231 is connected to the first connecting rod 3241, and the second friction block 3232 is connected to the output end of the linear transmission module. The second friction block 3232 drives the first friction block 3231 to move synchronously through static friction. Thus, in the process of driving the first adjustment plate 12 and the second adjustment plate 13 of the granule preparation metering mechanism 1, the first friction block 3231 and / or the first adjustment plate 12 can be limited at an appropriate position to switch the working state of the linkage assembly 323, that is, by limiting the first friction block 3231 and / or the first adjustment plate 12, the first connecting rod 3241 can be stationary, and the second connecting rod 3242 can move alone.

[0063] Specifically, the limiting structure is arranged on the granule preparation dispensing and dispensing mechanism 200 and / or the limiting structure is arranged on the granule preparation metering mechanism 1, and is used to limit the first friction block 3231 and / or the first adjusting plate 12. The limiting structure limits the first friction block 3231 and / or the first adjusting plate 12, so that the linkage assembly 323 has two working states. The first working state of the linkage assembly 323 is that the limiting structure limits the first friction block 3231 and / or the first adjusting plate 12, and the second friction block 3232 moves alone; the second working state of the linkage assembly 323 is that the limiting structure releases the limit on the first friction block 3231 and / or the first adjusting plate 12, and the second friction block 3232 moves synchronously with the first friction block 3231.

[0064] like Figures 19 to 21 As shown, in some possible embodiments, the limiting structure includes a metering limiting structure provided on the granule preparation metering mechanism 1 , and the metering limiting structure is used to limit the first adjusting plate 12 .

[0065] Specifically, the first adjustment plate 12 moves back and forth between the feed port 1112 and the discharge port 1121, and the metering limit structure includes a first metering limit structure and a second metering limit structure. The first metering limit structure is used to limit the first adjustment plate 12 at a side of the first adjustment plate 12 facing the second adjustment plate 13 corresponding to the discharge port 1121, and the second metering limit structure is used to limit the first adjustment plate 12 at a side of the first adjustment plate 12 facing the second adjustment plate 13 corresponding to the feed port 1112.

[0066] Preferably, in some specific embodiments, the first metering limit structure is the side wall of the metering cavity away from the linear transmission module. The first adjusting plate 12 is provided with a first guide groove 121, and the side wall of the metering cavity is provided with a first guide protrusion 1114 that cooperates with the first guide groove 121. The end of the first guide groove 121 away from the linear transmission module is closed. When the side of the first adjusting plate 12 close to the second adjusting plate 13 is aligned with the side of the feed port 1112 close to the discharge port 1121, the end of the first guide groove 121 away from the linear transmission module abuts against the first guide protrusion 1114. The second metering limit structure is the first guide protrusion 1114.

[0067] like Figure 4 , Figures 7 to 9 As shown, in some other possible embodiments, the limiting structure includes a drug dispensing limiting structure 325 disposed on the granular preparation dispensing mechanism 200 , and the drug dispensing limiting structure 325 is used to limit the first friction block 3231 .

[0068] Specifically, the medicine discharging limiting structure 325 includes a limiting plate 3251 and a limiting column. The limiting plate 3251 is arranged along a length direction perpendicular to the linear transmission module and connected to the first friction block 3231. The limiting column is used to abut against the limiting plate 3251 for limiting, and includes a first limiting column 3252 arranged on a side of the limiting plate 3251 close to the first connecting rod 3241, and a second limiting column 3253 arranged on a side of the limiting plate 3251 away from the first connecting rod 3241. The first limiting column 3252 and the second limiting column 3253 are spaced apart from each other, and the limiting plate 3251 reciprocates between the first limiting column 3252 and the second limiting column 3253.

[0069] In some specific embodiments, during the process of the output end of the linear transmission module moving toward the first direction, the first connecting rod 3241 moves synchronously with the output end of the linear transmission module under the action of static friction, and when the limit plate 3251 abuts against the first limit column 3252, the first adjustment plate 12 moves toward one side of the second adjustment plate 13 to a position corresponding to the discharge port 1121. At this time, if the output end of the linear transmission module continues to move toward the first direction, the first connecting rod 3241 is stationary, and the end of the second connecting rod 3242 approaches the end of the first connecting rod 3241, that is, the second adjustment plate 13 moves toward the first direction. An adjustment plate 12 gradually approaches; in the process of the output end of the linear transmission module moving toward the second direction, the first connecting rod 3241 moves synchronously with the output end of the linear transmission module under the action of static friction, and when the limit plate 3251 abuts against the second limit column 3253, the first adjustment plate 12 moves toward one side of the second adjustment plate 13 to the position corresponding to the feed port 1112. At this time, if the output end of the linear transmission module continues to move in the second direction, the end of the second connecting rod 3242 will gradually move away from the end of the first connecting rod 3241, that is, the second adjustment plate 13 gradually moves away from the first adjustment plate 12.

[0070] By limiting the first friction block 3231 and / or the first adjusting plate 12 through the limiting structure, the working state of the linkage component 323 can be switched. The operator only needs to adjust the limiting structure to a suitable position, which further simplifies the control process of the granular preparation adjusting and dispensing mechanism 200.

[0071] The metering limit structure and the medicine dispensing limit structure 325 can be provided at the same time, or one of them can be provided. Preferably, the medicine dispensing limit structure 325 is provided on the granule preparation dispensing mechanism 200, and whether to provide the metering limit structure for limiting the first adjusting plate 12 on the granule preparation metering mechanism 1 can be selected.

[0072] The first friction block 3231 and the second friction block 3232 are at least partially in contact, and the contact surface between the first friction block 3231 and the second friction block 3232 extends along the length direction of the linear transmission module; a pre-tightening structure 3234 is arranged between the first friction block 3231 and the second friction block 3232, for providing a pre-tightening force for the first friction block 3231 and the second friction block 3232 to squeeze each other, and the pre-tightening structure 3234 can ensure the stability of the friction force between the first friction block 3231 and the second friction block 3232, and can adjust the degree of mutual squeezing between the first friction block 3231 and the second friction block 3232.

[0073] like Fig.12 and Fig.13 As shown, the pre-tightening structure 3234 is arranged perpendicular to the contact surface between the first friction block 3231 and the second friction block 3232.

When the cavity moves to correspond to the discharge port 1121, the granular preparation is discharged from the discharge port 1121.

[0120] S5: the first adjusting plate 12 stops moving, and the second connecting rod 3242 drives the second adjusting plate 13 to move toward the first adjusting plate 12 until it is in contact with the first adjusting plate 12 .

[0121] In the process of the active slider 3212 driving the driven slider 3222 to move synchronously in the first direction through the linkage assembly 323, when the limit plate 3251 moves to abut against the first limit column 3252, the side opposite to the first adjustment plate 12 and the second adjustment plate 13 moves to be aligned with the side of the discharge port 1121 away from the feed port 1112.
