[0056] like Figures 1 to 26 As shown in this embodiment of the invention, a granule preparation dispensing device is introduced, comprising a medicine bottle assembly 100 for containing granule preparations and a granule preparation 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 mounted on the granule preparation dispensing mechanism 200, which drives the granule preparation metering mechanism 1. The granule preparation dispensing mechanism 200 drives the granule preparation metering mechanism 1, realizing automatic metering and dispensing of the granule preparations in the medicine bottle assembly 100, thereby improving the automation level of dispensing traditional Chinese medicine formula granule preparations.

[0057] The granule dosage form metering mechanism 1 includes a metering body 11, within which a metering chamber is provided. An inlet 1112 is located on the top wall of the metering chamber, and an outlet 1121 is located on the bottom wall. A dispensing plate, capable of sliding along the chamber wall, is disposed within the metering chamber. Vertically, the inlet 1112 and outlet 1121 are staggered. Specifically, the inlet 1112 and outlet 1121 are arranged along the sliding direction of the dispensing plate, and their projections on the same horizontal plane do not overlap.

[0058] The upper end surface of the dispensing plate is in abutting and sliding fit with the top wall of the metering cavity, the lower end surface of the dispensing plate is in abutting and sliding fit with the bottom wall of the metering cavity, and the left and right side surfaces of the dispensing plate are in abutting and sliding fit with the left and right side walls of the metering cavity along the sliding direction of the dispensing plate.

After the granular preparation metering mechanism 1 is mounted on the bottle mouth of the medicine bottle 2, the medicine bottle assembly 100 is inverted as a whole and is mounted on the granular preparation dispensing mechanism 200.

[0060] In the process of dispensing the granular preparation, the first dispensing plate 12 and the second dispensing plate 13 are away 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 cavity. The cavity is in communication with the feeding port 1112 and the discharging port 1121 alternatively, and specifically, when the cavity is in communication with the feeding port 1112, the granular preparation in the medicine bottle assembly 100 falls into the cavity between the first dispensing plate 12 and the second dispensing plate 13, and the cavity is filled with the granular preparation, so that the granular preparation is quantitatively dispensed, and when the cavity is in communication with the discharging port 1121, the granular preparation in the cavity is output. Therefore, the granular preparation in the medicine bottle assembly 100 is quantitatively output.

[0061] Embodiment one

[0062] In the prior art, in the process of disassembling, assembling and moving the medicine bottle assembly 100, the first dispensing plate 12 and the second dispensing plate 13 of the granular preparation metering mechanism 1 are prone to displacement, which causes the granular preparation in the medicine bottle assembly 100 to be spilled. In order to solve the technical problem, the granular preparation metering mechanism 1 is provided in the embodiment of the utility model, as shown in the figure. Figures 15 to 26

[0063] In the embodiment of the utility model, the granular preparation metering mechanism 1 comprises a metering main body 11, and the metering main body 11 defines a metering cavity, and the metering cavity is provided with a first dispensing plate 12 and a second dispensing plate 13 which can move and slide.

[0064] ​The first side of the metering cavity is provided with an opening, and the first dispensing plate 12 and the second dispensing plate 13 are sequentially arranged in a direction close to the opening; the second dispensing plate 13 is provided with a first positioning structure between the metering body 11, and the first dispensing plate 12 is clamped between the second dispensing plate 13 and the side wall of the second side of the metering cavity opposite to the first side. The side wall of the second side of the metering cavity is arranged opposite to the opening of the first side, and the side wall of the second side of the metering cavity is arranged as a structure capable of limiting the first dispensing plate 12. Specifically, the side wall of the second side can be a closed structure or a hollow structure, which can abut against the side of the first dispensing plate 12 away from the second dispensing plate 13.

[0065] At the initial time, the second dispensing plate 13 is limited in the metering cavity through the first positioning structure, the side of the first dispensing plate 12 away from the second dispensing plate 13 is attached to the side wall of the second side of the metering cavity, the side of the first dispensing plate 12 close to the second dispensing plate 13 is attached to the second dispensing plate 13, and the first dispensing plate 12 is limited between the second dispensing plate 13 and the side wall of the second side of the metering cavity, so as to lock the relative position between the first dispensing plate 12, the second dispensing plate 13 and the metering body 11. During the disassembly and movement of the medicine bottle assembly 100, the granular preparation in the medicine bottle assembly 100 will not be spilled, thereby improving the reliability and stability.

[0066] The first positioning structure includes a first clamping convex 131 and a first clamping groove 1122 in clamping cooperation.

[0067] In some possible embodiments, the first clamping convex 131 is arranged on the second dispensing plate 13, and the first clamping groove 1122 is arranged on the metering body 11 at a position corresponding to the first clamping convex 131.

[0068] In another possible embodiment, the first clamping convex 131 is arranged on the metering body 11, and the first clamping groove 1122 is arranged on the second dispensing plate 13 at a position corresponding to the first clamping convex 131.

[0069] As Figures 21 to 24As shown, in some specific embodiments, the first clamping protrusion 131 is arranged on the second dispensing plate 13, and the first clamping groove 1122 is arranged on the inner wall of the metering cavity, and the arrangement position of the first clamping groove 1122 corresponds to the position of the first clamping protrusion 131 when the second dispensing plate 13 is in the initial state. When the second dispensing plate 13 moves to the initial state, that is, the side of the first dispensing plate 12 away from the second dispensing plate 13 is attached to the side wall of the second side of the metering cavity, and the side of the second dispensing plate 13 close to the first dispensing plate 12 is attached to the first dispensing plate 12, the first clamping protrusion 131 is clamped in the first clamping groove 1122, thereby limiting the first dispensing plate 12 and the second dispensing plate 13, and when the first dispensing plate 12 and the second dispensing plate 13 are not driven by the granular preparation dispensing mechanism 200, the first dispensing plate 12 and the second dispensing plate 13 will not produce relative displacement with the metering main body 11.

[0070] The first positioning structure is arranged between the top wall of the metering cavity and the second dispensing plate 13, and / or the first positioning structure is arranged between the bottom wall of the metering cavity and the second dispensing plate 13, and / or the first positioning structure is arranged between the left and right side walls of the metering cavity and the second dispensing plate 13.

[0071] Preferably, in order to ensure stable limiting of the second dispensing plate 13, at least two groups of first positioning structures are arranged between the second dispensing plate 13 and the inner wall of the metering cavity, and the at least two groups of positioning structures are respectively arranged close to the left and right side walls of the metering cavity.

[0072] In some specific embodiments, the first positioning structure is arranged between the bottom wall of the metering cavity and the second dispensing plate 13, and the first positioning structure is arranged in two groups, and the two groups of positioning structures are respectively arranged close to the left and right side walls of the metering cavity, and the two groups of first positioning structures are axially symmetrically distributed relative to the bisector of the bottom wall of the metering cavity and the second dispensing plate 13.

[0073] As shown in the drawings, Figure 21 In some preferred embodiments, the side of the first clamping groove 1122 where the first clamping protrusion 131 is clamped is provided with a first guide groove corresponding to the first clamping protrusion 131, the height of the first clamping protrusion 131 is less than or equal to the depth of the first clamping groove 1122, and greater than the depth of the first guide groove.

[0074] Specifically, the first clamping protrusion 131 protrudes downward from the lower end surface of the second dispensing plate 13, and the first clamping groove 1122 is recessed downward from the bottom wall of the metering cavity. One side of the first clamping groove 1122 away from the second side of the metering cavity is provided with a first guide groove. During sliding of the second dispensing plate 13, the first clamping protrusion 131 is clamped into the first clamping groove 1122 through the first guide groove, or is separated from the first clamping groove 1122. The first guide groove can make the first clamping protrusion 131 be clamped into the first clamping groove 1122 or be separated from the first clamping groove 1122 smoothly, and can avoid the second dispensing plate 13 being clamped completely.

[0075] Preferably, the first clamping groove 1122 is arranged at the edge of the one end of the bottom wall of the metering cavity away from the second side of the metering cavity, and the first guide groove is arranged between the edge of the one end of the bottom wall of the metering cavity away from the second side of the metering cavity and the first guide groove.

[0076] As shown in the drawings, in some preferred embodiments, along the sliding direction of the second dispensing plate 13, the two ends of the first clamping protrusion 131 are respectively provided with guide surfaces, and along the direction from the middle of the first clamping protrusion 131 to the two ends of the first clamping protrusion 131, the height of the first clamping protrusion 131 gradually decreases. Figure 24

[0077] Specifically, the guide surface can be a slope or a curved surface.

[0078] The one end of the first clamping protrusion 131 connected with the second dispensing plate 13 is the root of the first clamping protrusion 131, and the one end of the first clamping protrusion 131 away from the second dispensing plate 13 is the end of the first clamping protrusion 131.

[0079] The width of the first clamping protrusion 131 gradually decreases along the direction close to the end of the first clamping protrusion 131.

[0080] In some specific embodiments, the first clamping protrusion 131 is provided with a first guide surface on the side close to the second side of the metering cavity, and along the direction close to the second side of the metering cavity, the first guide surface extends obliquely or curvedly towards the direction close to the lower end surface of the second dispensing plate 13.

[0081] The second clamping protrusion 1123 is provided with a second guide surface on the side away from the second side of the metering cavity, and along the direction away from the second side of the metering cavity, the first guide surface extends obliquely or curvedly towards the direction close to the lower end surface of the second dispensing plate 13.

[0082] Preferably, along the sliding direction of the second dispensing plate 13, the vertical bisector of the first clamping protrusion 131 is a body shape.

[0083] ​Preferably, along the sliding direction of the second adjusting plate 13, that is, along the direction from the first side of the metering cavity to the second side, the size of the first card protrusion 131 is adapted to the size of the first card groove 1122.

[0084] In some preferred embodiments, when the granule dosage metering mechanism 1 is in its initial state, the side of the second dispensing plate 13 away from the first dispensing plate 12 is flush with the outer side of the first side of the metering cavity, or the side of the second dispensing plate 13 away from the first dispensing plate 12 is disposed in the opening of the metering cavity and is close to the outer side of the first side of the metering cavity. Thus, without increasing the size of the metering body 11, the contact area between the first dispensing plate 12, the second dispensing plate 13 and the inner wall of the metering cavity is increased, which is beneficial to improving the guiding of the first dispensing plate 12 and the second dispensing plate 13.

[0085] The metering body 11 includes a groove-shaped part 111 and a plate part 112. The plate part 112 is installed at the groove opening of the groove-shaped part 111 and is spliced ​​with the groove-shaped part 111 to form a metering cavity.

[0086] In the prior art, the plate portion 112 is usually installed on the groove portion 111 by screws or other connecting parts, which has the problems of low installation efficiency and poor appearance of the granule dosage metering mechanism 1.

[0087] In this embodiment of the utility model, the plate portion 112 and the groove portion 111 are inserted into each other.

[0088] Specifically, the groove of the groove portion 111 is provided with a plug groove 1115, which extends in a direction parallel to the bottom of the groove portion 111, and one end of the plug groove 1115 is open; the plate portion 112 is inserted into the plug groove 1115.

[0089] like Figures 17 to 21 As shown, the bottom of the insertion groove 1115 is set as a plane, and the distance between the groove walls of the insertion groove 1115 gradually decreases in the direction away from the bottom of the insertion groove 1115; the plate portion 112 is in contact with the bottom of the insertion groove 1115, and along the extension direction of the insertion groove 1115, both sides of the plate portion 112 are in contact with the groove walls of the insertion groove 1115.

[0125] Embodiment two

[0126] In the embodiment of the utility model, a granular preparation dispensing mechanism 200 is introduced, which is used to drive the granular preparation metering mechanism 1 in the above embodiment one. As shown in the figure, the whole dispensing process can be completed by driving with one power source, which simplifies the control system and control process of the granular preparation dispensing device, reduces the operation difficulty and error rate of the device, and at the same time, reduces the cost. Figures 1 to 14

[0127] The granular preparation dispensing mechanism 200 comprises a first connecting rod 3241 and a second connecting rod 3242, and the first connecting rod 3241 and the second connecting rod 3242 are respectively used to connect the first dispensing plate 12 and the second dispensing plate 13 of the granular preparation metering mechanism 1. The granular preparation dispensing mechanism 200 further comprises 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 drivingly connected with the first connecting rod 3241 through a clutch structure. Thus, in the process of moving the second connecting rod 3242 driven by the linear transmission module, the first connecting rod 3241 can be selectively driven to move synchronously or only the second connecting rod 3242 can be driven to move through the clutch structure, so that the first dispensing plate 12 and the second dispensing plate 13 of the granular preparation metering mechanism 1 can be driven.

[0128] As shown in the figure, 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 to limit the first connecting rod 3241, and / or the limiting structure is used to limit the first dispensing plate 12, so that the second dispensing plate 13 is driven by the second connecting rod 3242 to move alone through the linear transmission module. Figure 5 、 Figure 6 、 Figures 8 to 10 The limiting structure is used to limit the first connecting rod 3241, and / or the limiting structure is used to limit the first dispensing plate 12, so that the second dispensing plate 13 is driven by the second connecting rod 3242 to move alone through the linear transmission module.

[0129] ​Specifically, the linkage assembly 323 includes 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 static friction.

[0130] Therefore, during the driving of the first and second dosing plates 12 and 13 of the granular preparation metering mechanism 1, the switching of the working state of the linkage assembly 323 can be realized by limiting the first friction block 3231 and / or the first dosing plate 12 at a proper position, that is, by limiting the first friction block 3231 and / or the first dosing plate 12, the first connecting rod 3241 can be stationary, and the second connecting rod 3242 can move alone.

[0131] Specifically, the limiting structure is arranged on the granular preparation dosing and dispensing mechanism 200 and / or the limiting structure is arranged on the granular preparation metering mechanism 1, for limiting the first friction block 3231 and / or the first dosing plate 12. By limiting the first friction block 3231 and / or the first dosing plate 12 through the limiting structure, the linkage assembly 323 has two working states.

[0132] The first working state of the linkage assembly 323 is that the limiting structure limits the first friction block 3231 and / or the first dosing plate 12, and the second friction block 3232 moves alone; and the second working state of the linkage assembly 323 is that the limiting structure releases the limitation of the first friction block 3231 and / or the first dosing plate 12, and the second friction block 3232 moves synchronously with the first friction block 3231.

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.

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 static, 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, and when the limiting plate 3251 abuts against the second limiting column 3253, the first adjusting plate 12 moves to the position corresponding to the feeding port 1112 on one side of 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.

[0190] S4: The first adjusting plate 12 and the second adjusting plate 13 move synchronously, so that the side of the first adjusting plate 12 facing the second adjusting plate 13 moves to be aligned with the side of the discharge port 1121 away from the feed port 1112.

[0191] During this process, the active slider 3212 drives the driven slider 3222 to move synchronously in the first direction via the linkage component 323. The granular formulation is temporarily stored in the cavity between the first dispensing plate 12 and the second dispensing plate 13, and moves with the first dispensing plate 12 and the second dispensing plate 13. When the cavity moves to correspond with the discharge port 1121, the granular formulation is output from the discharge port 1121.

[0192] 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.

[0193] During the process of the active slider 3212 driving the driven slider 3222 to move synchronously in the first direction through the linkage component 323, when the limiting plate 3251 moves to abut against the first limiting post 3252, the side opposite to the first adjusting plate 12 and the second adjusting plate 13 moves to align with the side of the discharge port 1121 away from the feed port 1112. At this time, the driven slider 3222 stops moving, and the active slider 3212 continues to move in the first direction until the active slider 3212 moves to the point where the baffle 3213 corresponds to the first grating sensor 3131. At this time, the active slider 3212 stops moving, and the first adjusting plate 12 and the second adjusting plate 13 are in contact.

[0222] Preferred, such as Figures 4 to 7 As shown, along the vertical direction perpendicular to the main body 3 to the support 4, the scanning range of the read / write module 5 is larger than the size of the storage module 14; and along the horizontal direction perpendicular to the main body 3 to the support 4, the scanning range of the read / write module 5 is also larger than the size of the storage module 14. This ensures the reliability of the read / write module 5's scanning of the storage module 14 and improves the efficiency of the granule preparation dispensing mechanism 200 in acquiring information about the granule preparation stored in the vial assembly 100.

[0223] Preferably, in some possible embodiments, a tenon 411 is provided on at least one side wall of the support groove 41, the tenon 411 protruding into the support groove 41, and a mortise 16 is provided on the side wall of the granule dosage metering mechanism 1 to mate with the tenon 411. Both the mortise 16 and the tenon 411 extend along the installation direction of the granule dosage metering mechanism 1, that is, they extend vertically. During the installation of the granule dosage metering mechanism 1, the tenon 411 is inserted into the mortise 16, which on the one hand improves the installation stability of the granule dosage metering mechanism 1, and on the other hand improves the positioning effect between the granule dosage metering mechanism 1 and the granule dosage dispensing mechanism 200, ensuring the accuracy of the assembly angle of the granule dosage metering mechanism 1.

[0224] Preferably, in some other possible embodiments, a magnetic sensing element 412 is provided on at least one side wall of the support groove 41, and a magnetic block 15 cooperating with the magnetic sensing element 412 is provided on the side wall of the granule dosage metering mechanism 1. Specifically, the magnetic sensing element 412 can be a reed switch, which scans the position of the magnetic block 15 to calibrate the relative position between the granule dosage dispensing mechanism 200 and the granule dosage metering mechanism 1.

[0225] Based on the relative positions of the storage module 14 and the read / write module 5, the operator can quickly and accurately determine the installation angle of the medicine bottle assembly 100. By setting mutually cooperating tenons 16 and tenons 411, as well as mutually cooperating magnetic blocks 15 and magnetic sensing elements 412 between the granule preparation metering mechanism 1 and the support groove 41, the installation accuracy between the granule preparation metering mechanism 1 and the granule preparation dispensing mechanism 200 can be further improved, so that the dispensing plate of the granule preparation metering mechanism 1 and the driving end of the granule preparation dispensing mechanism 200 can be precisely fitted together, ensuring the reliability of the cooperation between the granule preparation dispensing mechanism 200 and the granule preparation metering mechanism 1.

[0226] like Figure 22As shown, the first and second dispensing plates 12 and 13 of the granular preparation metering mechanism 1 are both in transmission connection with the driving end of the granular preparation dispensing mechanism 200.

[0227] Specifically, as shown in Figures 8 to 12 The driving transmission assembly 32 is installed on the mounting bottom plate 311, and includes a linear transmission module, a guide rail sliding block module 322, a clutch structure, a first connecting rod 3241, a second connecting rod 3242, and a driving module 326. The clutch structure includes a linkage assembly 323 and a dispensing limiting structure 325.

[0228] The linear transmission module and the guide rail sliding block module 322 both extend in the direction from the body portion 3 to the support portion 4. The first connecting rod 3241 is fixedly connected to the output end of the linear transmission module, and the second connecting rod 3242 is in transmission connection with the output end of the linear transmission module through the clutch structure. The first and second connecting rods 3241 and 3242 are respectively used to drive the first and second dispensing plates 12 and 13 to slide.

[0229] Specifically, as shown in Figure 9 and Figure 12 The linear transmission module is a screw rod and sliding block module 321, which includes a screw rod 3211, a sliding rail 3214, and a driving sliding block 3212. The screw rod 3211 and the sliding rail 3214 are parallel to each other, the driving sliding block 3212 is in sliding fit with the sliding rail 3214, and the driving sliding block 3212 is in threaded fit with the screw rod 3211. The guide rail sliding block module 322 includes a guide rail 3221 and a driven sliding block 3222. The driven sliding block 3222 is in sliding fit with the guide rail 3221, and the guide rail 3221 is parallel to the sliding rail 3214.

[0230] One end of the second connecting rod 3242 is fixed on the driving sliding block 3212, and one end of the first connecting rod 3241 is fixed on the driven sliding block 3222. The driving sliding block 3212 and the driven sliding block 3222 are in transmission connection through the linkage assembly 323. The driving sliding block 3212 drives the driven sliding block 3222 to slide synchronously through the static friction force provided by the linkage assembly 323. The dispensing limiting structure 325 is used to limit the driven sliding block 3222 to be stationary, so as to realize the relative sliding between the driving sliding block 3212 and the driven sliding block 3222.

[0231] The dispensing limiting structure 325 is arranged in the granular preparation dispensing mechanism 200, and is used to limit the first connecting rod 3241 when the first dispensing plate 12 moves to the first direction corresponding to the discharge port 1121, and when the first dispensing plate 12 moves to the second direction opposite to the first direction corresponding to the feeding port 1112.

[0232] In some specific embodiments, the first direction is a direction from the body part 3 to the support part 4, and the second direction is a direction from the support part 4 to the body part 3.

[0233] Specifically, the medicine outlet limiting structure 325 includes a limiting plate 3251, a first limiting column 3252, and a second limiting column 3253. The limiting plate 3251 is fixed on the driven slider 3222. The first limiting column 3252 is arranged on a side of the limiting plate 3251 close to the support part 4. The second limiting plate 3251 is arranged on a side of the limiting plate 3251 away from the support part 4.

[0234] Preferably, the linkage assembly 323 and the first connecting rod 3241 are both connected to the limiting plate 3251.

[0235] In some possible embodiments, the granular preparation metering mechanism 1 is provided with metering limiting structure. The metering limiting structure is used to limit the first dosing plate 12 when the first dosing plate 12 moves to the first direction corresponding to the discharge port 1121, and when the first dosing plate 12 moves to the second direction opposite to the first direction corresponding to the feeding port 1112.

[0236] The discharge port 1121 is arranged on a side of the feeding port 1112 away from the body part 3. The side wall of the metering cavity of the granular preparation metering mechanism 1 away from the body part 3 is closed. When the side of the first dosing plate 12 close to the second dosing plate 13 is aligned with the side of the discharge port 1121 away from the feeding port 1112, the first dosing plate 12 abuts against the side wall of the metering cavity away from the body part 3. At this time, the first limiting column 3252 abuts against the limiting plate 3251.

[0237] The first dosing plate 12 is provided with a first guide groove 121 on the top. The top wall of the metering cavity is provided with a first guide convex 1114 matched with the first guide groove 121. The end of the first guide groove 121 away from the body part 3 is closed. When the side of the first dosing plate 12 close to the second dosing plate 13 is aligned with the side of the feeding port 1112 close to the discharge port 1121, the end of the first guide groove 121 away from the body part 3 abuts against the first guide convex 1114. At this time, the second limiting column 3253 abuts against the limiting plate 3251.

[0238] The end of the shell 31 away from the support part 4 is closed by the driving module 326.

[0239] As Figure 5 and Figure 6As shown, in some specific embodiments, the drive module 326 includes a drive motor 3261, a coupling 3263, and a motor bracket 3262. Specifically, the motor bracket 3262 extends vertically, and its bottom bends towards the interior of the housing 31. The bent portion of the bottom of the motor bracket 3262 fits against the top of the mounting base plate 311, and the bent portion of the bottom of the motor bracket 3262 is connected to the mounting base plate 311 by screws and / or bolts. The vertically extending portion of the motor bracket 3262 closes the end of the housing 31 away from the second connecting rod 3242.

[0240] The working end of the drive motor 3261 extends into the housing 31 and is connected to the lead screw 3211 via a coupling 3263.

[0241] like Figure 4 As shown, in some specific embodiments, the support part 4 is a horizontally extending rectangular frame. The end of the support part 4 near the main body part 3 bends upward to form a second bend part 42. This facilitates the assembly between the support part 4 and the main body part 3, and also avoids the drive end of the granule preparation dispensing mechanism 200, so that the first connecting rod 3241 and the second connecting rod 3242 of the granule preparation dispensing mechanism 200 can extend smoothly to the hollowed-out part at the bottom of the support groove 41.

[0242] In some specific embodiments, the end of the first connecting rod 3241 away from the driven slider 3222 and the end of the second connecting rod 3242 away from the active slider 3212 are respectively provided with a first driving post and a second driving post extending in the vertical direction. The bottom of the first dispensing plate 12 and the second dispensing plate 13 are respectively provided with a first driving hole and a second driving hole. The shape of the first driving hole is adapted to the shape of the first driving post, and the shape of the second driving hole is adapted to the shape of the second driving post. When the granule preparation metering mechanism 1 is installed in the support groove 41, the first driving hole is sleeved on the first driving post, and the second driving hole is sleeved on the second driving post.

The granule dosage form dispensing mechanism 200 is provided with one or more parts.

[0244] Preferably, in some possible embodiments, the granule formulation dispensing mechanism 200 is provided with multiple units.

[0245] Specifically, the bearing part 300 is provided in a strip shape, and the granular preparation dispensing mechanisms 200 extend along the width direction of the bearing part 300, and the plurality of granular preparation dispensing mechanisms 200 are arranged along the length direction of the bearing part 300.

[0246] One end of the bearing groove 41 of the granular preparation dispensing mechanism 200 can be directed to the same side of the bearing part 300, or can be directed to different sides of the bearing part 300.

[0247] Preferably, one end of the bearing groove 41 of the granular preparation dispensing mechanism 200 is directed to the same side of the bearing part 300.

[0248] Preferably, the bottom of each granular preparation dispensing mechanism 200 is provided with a bearing frame 6, and each granular preparation dispensing mechanism 200 is installed on the bearing part 300 through the bearing frame 6.

[0250] The first bearing beam 61 extends along the length direction of the granular preparation dispensing mechanism 200, and two first bearing beams 61 are arranged near the left and right side edges of the granular preparation dispensing mechanism 200 respectively. The first bearing beam 61 is arranged near the edge of the bearing part 300 away from the bearing groove 41, and a recess is arranged on the first bearing beam 61. The second bearing beam 62 is arranged at the recess and extends along the width direction of the granular preparation dispensing mechanism 200. The second bearing beam 62 is connected to the two first bearing beams 61 through a third connecting piece and connected to the bearing part 300 through a fourth connecting piece. The end of the first bearing beam 61 near the bearing groove 41 is flush with the edge of the bearing part 300 near the bearing groove 41, and the third bearing beam 63 is arranged between the end of the first bearing beam 61 near the bearing groove 41 and the side surface of the bearing part 300 near the bearing groove 41. The third bearing beam 63 is connected to the end of each first bearing beam 61 through a fifth connecting piece and connected to the bearing part 300 through a sixth connecting piece.

[0251] In some specific embodiments, the first bearing beam 61 is installed on the bottom of the mounting bottom plate 311 through a screw. The top of the first bearing beam 61 is flush with the bottom of the mounting bottom plate 311.
