[0052] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments will be clearly and completely described below in combination with the drawings in the embodiments of the present application. The following embodiments are used to illustrate the present application, but not to limit the scope of the present application.

[0054] In the description of the utility model, it needs to explain, unless another explicit provision and limitation, the term "installation", "connection", "connect" should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium. For ordinary skilled in the art, the specific meaning of the above-mentioned terms in the utility model can be understood according to the specific circumstances.

[0055] As Figures 1 to 26 The utility model discloses a granular preparation dispensing device, which comprises a medicine bottle assembly 100 for containing granular preparation and a granular preparation dispensing mechanism 200, the medicine bottle assembly 100 comprises a medicine bottle 2 and a granular preparation metering mechanism 1 for quantitatively dispensing granular preparation, the medicine bottle assembly 100 is installed on the granular preparation dispensing mechanism 200, and the granular preparation dispensing mechanism 200 is used for driving the granular preparation metering mechanism 1 to operate. The granular preparation dispensing mechanism 200 drives the granular preparation metering mechanism 1, realizes automatic metering and discharging of the granular preparation in the medicine bottle assembly 100, and improves the automation level of dispensing of traditional Chinese medicine formula granular preparation.

[0056] The granular preparation metering mechanism 1 comprises a metering main body 11, a metering cavity is arranged in the metering main body 11, a feeding port 1112 is arranged on the top wall of the metering cavity, a discharging port 1121 is arranged on the bottom wall of the metering cavity, and a dispensing plate is arranged in the metering cavity and can slide along the cavity wall of the metering cavity. In the vertical direction, the feeding port 1112 and the discharging port 1121 are mutually staggered. Specifically, the feeding port 1112 and the discharging port 1121 are arranged along the sliding direction of the dispensing plate, and the projection of the feeding port 1112 and the discharging port 1121 in the same horizontal plane does not overlap.

[0057] The upper end face of the dispensing plate is attached to and slidably connected with the top wall of the metering cavity, the lower end face of the dispensing plate is attached to and slidably connected with the bottom wall of the metering cavity, and the left and right side faces of the dispensing plate are respectively attached to and slidably connected with the left and right side walls of the metering cavity along the sliding direction of the dispensing plate. Specifically, the dispensing plate slides along the length direction of the metering cavity. The dispensing plate comprises a first dispensing plate 12 and a second dispensing plate 13 arranged along the length direction of the metering cavity, and the opposite sides of the first dispensing plate 12 and the second dispensing plate 13 can be attached to each other.

[0058] The top wall of the dispensing chamber is provided with an upwardly extending mounting port 1111, which is used to mate with the mouth of the medicine bottle 2 containing granular preparations. The mouth of the bottle is installed at the mounting port 1111, and the feed inlet 1112 is located within the surrounding area of ​​the mounting port 1111. After the granular preparation metering mechanism 1 is installed on the mouth of the medicine bottle 2, the medicine bottle assembly 100 is inverted and installed on the granular preparation dispensing mechanism 200.

[0059] During the dispensing of granule formulations, the first dispensing plate 12 and the second dispensing plate 13 are spaced apart to form a cavity for temporary storage of the granule formulation. This cavity allows the granule formulation from the vial assembly 100 to fall into the dispensing cavity. The cavity is selectively connected to either the inlet 1112 or the outlet 1121. Specifically, when the cavity is connected to the inlet 1112, the granule formulation from the vial assembly 100 falls into the cavity between the first dispensing plate 12 and the second dispensing plate 13, filling the cavity and achieving quantitative dispensing of the granule formulation. When the cavity is connected to the outlet 1121, the granule formulation within the cavity is discharged. Thus, quantitative dispensing of the granule formulation from the vial assembly 100 is achieved.

[0060] Example 1

[0061] The existing granule dosage metering mechanism 1 generally uses two power sources to drive the first dispensing plate 12 and the second dispensing plate 13 respectively, which increases the cost of the granule dosage metering mechanism 1. Moreover, in the process of dispensing granules, it is necessary to control the two power sources to cooperate with each other, making the control process of granules cumbersome and the control system complex.

[0062] To solve the above-mentioned technical problems, this utility model provides a granule preparation dispensing mechanism 200, such as... Figures 1 to 14 As shown, the entire dispensing process can be completed by driving a single power source, which simplifies the control system and process of the granule dispensing device, reduces the difficulty of operation and error rate of the device, and at the same time reduces costs.

[0063] The granular preparation dispensing mechanism 200 comprises a first connecting rod 3241 and a second connecting rod 3242, the first connecting rod 3241 and the second connecting rod 3242 are respectively used for being connected with the first dispensing plate 12 and the second dispensing plate 13 of the granular preparation metering mechanism 1, and the granular preparation dispensing mechanism 200 further comprises a linear transmission module, an 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 in transmission connection with the first connecting rod 3241 through a clutch structure. Therefore, in the process that the linear transmission module drives 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, so that the first dispensing plate 12 and the second dispensing plate 13 of the granular preparation metering mechanism 1 can be driven.

[0064] As shown in Figure 5 , Figure 6 , Figures 8 to 10 , the clutch structure comprises a linkage assembly 323 and a limiting structure. The linkage assembly 323 is installed on the output end of the linear transmission module, the first connecting rod 3241 is connected with the linkage assembly 323, and the output end of the linear transmission module drives the first connecting rod 3241 to move through the static friction force provided by the linkage assembly 323. The limiting structure is used for limiting the first connecting rod 3241, and / or the limiting structure is used for limiting the first dispensing plate 12, so that the second dispensing plate 13 is driven by the linear transmission module through the second connecting rod 3242 to move alone.

[0065] Specifically, the linkage assembly 323 comprises a first friction block 3231 and a second friction block 3232, the first friction block 3231 is connected with the first connecting rod 3241, and the second friction block 3232 is connected with the output end of the linear transmission module. The second friction block 3232 drives the first friction block 3231 to move synchronously through the static friction force. Therefore, in the process of driving the first dispensing plate 12 and the second dispensing plate 13 of the granular preparation metering mechanism 1, the working state of the linkage assembly 323 can be switched by limiting the first friction block 3231 and / or the first dispensing plate 12 at a proper position, that is, the first connecting rod 3241 can be made stationary and the second connecting rod 3242 can be made to move alone by limiting the first friction block 3231 and / or the first dispensing plate 12.

[0066] Specifically, the limiting structure is arranged on the granular preparation dispensing mechanism 200 and / or the limiting structure is arranged on the granular preparation metering mechanism 1, and is used for limiting the first friction block 3231 and / or the first dispensing plate 12. The linkage assembly 323 has two working states by limiting the first friction block 3231 and / or the first dispensing plate 12 through the limiting structure.

[0067] The first working state of the linkage assembly 323 is that the limiting structure limits the first friction block 3231 and / or the first dispensing 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 first friction block 3231 and / or the first dispensing plate 12, and the second friction block 3232 moves synchronously with the first friction block 3231.

[0068] As shown in some possible embodiments, the limiting structure includes a metering limiting structure arranged on the granular preparation metering mechanism 1, and the metering limiting structure is used to limit the first dispensing plate 12. Figures 20 to 22

[0069] Specifically, the first dispensing plate 12 reciprocates between the feeding port 1112 and the discharging port 1121, and the metering limiting structure includes a first metering limiting structure and a second metering limiting structure, the first metering limiting structure is used to limit the first dispensing plate 12 at a side of the first dispensing plate 12 corresponding to the discharging port 1121, and the second metering limiting structure is used to limit the first dispensing plate 12 at a side of the first dispensing plate 12 corresponding to the feeding port 1112.

[0070] Preferably, in some specific embodiments, the first metering limiting structure is a side wall of a metering cavity away from the linear transmission module. The first dispensing plate 12 is provided with a first guide groove 121, and the side wall of the metering cavity is provided with a first guide convex 1114 matched with the first guide groove 121, an end of the first guide groove 121 away from the linear transmission module is closed, and when the side of the first dispensing plate 12 close to the second dispensing plate 13 is aligned with the side of the feeding port 1112 close to the discharging port 1121, the end of the first guide groove 121 away from the linear transmission module abuts against the first guide convex 1114. The second metering limiting structure is the first guide convex 1114.

[0071] As shown in some possible embodiments, the limiting structure includes a metering limiting structure arranged on the granular preparation metering mechanism 1, and the metering limiting structure is used to limit the first dispensing plate 12. Figure 5 Figures 8 to 10 As shown in some possible embodiments, the limiting structure includes a metering limiting structure arranged on the granular preparation metering mechanism 1, and the metering limiting structure is used to limit the first dispensing plate 12.

[0072] ​​Specifically, the medicine outlet limiting structure 325 includes a limiting plate 3251 and limiting columns. The limiting plate 3251 is arranged along a direction perpendicular to the length direction of the linear transmission module and is connected with the first friction block 3231. The limiting columns are used to abut against the limiting plate 3251 for limiting, including a first limiting column 3252 arranged on one side of the limiting plate 3251 close to the first connecting rod 3241 and a second limiting column 3253 arranged on one 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 from each other, and the limiting plate 3251 reciprocates between the first limiting column 3252 and the second limiting column 3253.

[0073] In some specific embodiments, during the movement of the output end of the linear transmission module in 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. When the limiting plate 3251 abuts against the first limiting column 3252, the first adjusting plate 12 moves to the position corresponding to the medicine outlet 1121 on the side facing the second adjusting plate 13. At this time, if the output end of the linear transmission module continues to move in 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 adjusting plate 13 gradually approaches the first adjusting plate 12. During the movement of the output end of the linear transmission module in 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. When the limiting plate 3251 abuts against the second limiting column 3253, the first adjusting plate 12 moves to the position corresponding to the medicine inlet 1112 on the side facing the second adjusting plate 13. 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 adjusting plate 13 gradually moves away from the first adjusting plate 12.

[0074] By limiting the first friction block 3231 and / or the first adjusting plate 12 through the limiting structure, the switching of the working state of the linkage assembly 323 can be realized. The operator only needs to adjust the limiting structure to the appropriate position, which further simplifies the control process of the granular preparation adjusting and medicine outlet mechanism 200.

[0075] The metering limiting structure and the medicine outlet limiting structure 325 can be set simultaneously or selectively. Preferably, the medicine outlet limiting structure 325 is arranged on the granular preparation adjusting and medicine outlet mechanism 200, and whether the metering limiting structure for limiting the first adjusting plate 12 is arranged on the granular preparation metering mechanism 1 can be selected.

[0076] The first friction block 3231 and the second friction block 3232 are in at least partial 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 provided between the first friction block 3231 and the second friction block 3232 to provide a pre-tightening force for the first friction block 3231 and the second friction block 3232 to press against each other. 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 pressing between the first friction block 3231 and the second friction block 3232.

[0077] like Figure 13 and Figure 14 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. The first friction block 3231 and / or the second friction block 3232 are provided with a strip hole 3233 through which the pre-tightening structure 3234 passes. The strip hole 3233 extends along the length direction of the linear transmission module.

[0078] The preload structure 3234 includes a preload rod and a compression spring.

[0079] In some possible embodiments, a slotted hole 3233 is disposed on the second friction block 3232, and a preload rod passes through the slotted hole 3233 on the second friction block 3232 and connects to the first friction block 3231. The preload rod abuts against the side of the second friction block 3232 away from the first friction block 3231 via a compression spring. Specifically, the first end of the preload rod is connected to the first friction block 3231, and the second end of the preload rod is provided with a radial protrusion. A compression spring is sleeved on the preload rod, with one end of the compression spring abutting against the radial protrusion and the other end of the compression spring abutting against the side of the second friction block 3232 away from the first friction block 3231.

[0080] In some possible embodiments, a strip-shaped hole 3233 is disposed on the first friction block 3231, and a preload rod passes through the strip-shaped hole 3233 on the first friction block 3231 and connects to the second friction block 3232. The preload rod abuts against the side of the first friction block 3231 away from the second friction block 3232 via a compression spring. Specifically, the first end of the preload rod is connected to the second friction block 3232, and the first end of the preload rod is provided with a radial protrusion. A compression spring is sleeved on the preload rod, with one end of the compression spring abutting against the radial protrusion and the other end of the compression spring abutting against the side of the first friction block 3231 away from the second friction block 3232.
