Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical medical device technology, specifically relating to a feeding wheel and a dispensing mechanism for traditional Chinese medicine decoction pieces. Background Technology

[0002] In the production process of traditional Chinese medicine (TCM), a set amount of medicinal herbs needs to be mixed and decocted together according to a predetermined dosage to form a TCM preparation. Weighing the prescribed weight of medicinal herbs according to the TCM formula is called dispensing. To improve the production efficiency and automation of TCM, a TCM decoction dispensing mechanism has been designed to achieve automatic dispensing of TCM decoction herbs.

[0003] In traditional Chinese medicine (TCM) decoction piece dispensing mechanisms, the feeding and distributing wheel is a core component. For example, Chinese utility model patent application number CN201821534385.X discloses a feeding and distributing wheel assembly for a TCM decoction piece dispensing mechanism. In use, the feeding and distributing wheel is installed on the discharge port of the feeding hopper, blocking the discharge port. A feeding gap S1 is formed between the side wall of the feeding hopper and the feeding and distributing wheel. The feeding hopper is equipped with bristles that block the feeding gap. By driving the feeding and distributing wheel to rotate, the TCM decoction pieces are driven to press down on the bristles, causing the TCM decoction pieces to fall through the feeding gap.

[0004] Traditional Chinese medicine (TCM) decoction pieces come in various forms, and some pieces may be lightweight, prone to sticking, or have a smooth surface. During the feeding process, these pieces are susceptible to problems such as uneven feeding or slippage, leading to unstable feeding efficiency or material leakage. To improve the reliability of feeding, CN201821534385.X discloses a technical solution of adding assistive saw teeth on the tip of the feeding teeth.

[0005] However, in this solution, the assist saw teeth are directly set on the top of the feeding teeth. If the assist saw teeth are worn or damaged, the entire feeding wheel needs to be replaced, which increases maintenance costs and operational complexity.

[0006] In view of this, this utility model is hereby proposed. Utility Model Content

Detailed Implementation

[0056] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0057] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0058] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0059] In this embodiment of the utility model, a feeding wheel for dispensing traditional Chinese medicine decoction pieces is introduced.

[0060] like Figures 11 to 13 As shown, the feeding wheel 2 is provided with multiple rows of feeding teeth 221 evenly distributed along the circumference of the feeding wheel 2, and the feeding teeth 221 in the same row are staggered in the same direction along the circumference of the feeding wheel 2.

[0061] Specifically, the end of the feeding tooth 221 that is away from the axis of the feeding wheel 2 is the tooth tip of the feeding tooth 221, and the tooth tip of the feeding tooth 221 is located in the same cylindrical surface, which is coaxial with the feeding wheel 2.

[0062] The feeding surface 2211 of the feeding tooth 221 has a certain extension length along the radial direction of the feeding wheel 2. A saw blade 23 is detachably installed on the feeding surface 2211 of the feeding tooth 221. The assisting saw teeth 231 of the saw blade 23 are arranged on the side away from the axis of the feeding wheel 2, corresponding to the side of the feeding surface 2211 away from the axis of the feeding wheel 2.

[0063] By detachably mounting the serrated blade 23 onto the feeding surface 2211 of the feeding tooth 221, the auxiliary serrated teeth 231 on the serrated blade 23 increase the friction and contact area with the Chinese herbal medicine slices. This means that when the auxiliary serrated teeth 231 are worn or damaged, only the serrated blade 23 needs to be replaced, without replacing the entire feeding wheel 2, which reduces maintenance costs and simplifies the maintenance process. In addition, the auxiliary serrated teeth 231 can be upgraded by replacing the serrated blade 23, further improving the applicability of the feeding wheel 2 to Chinese herbal medicine slices of different shapes.

[0064] like Figure 12 As shown, in this embodiment, in the circumferential direction of the feeding wheel 2, the first side of the feeding tooth 221 is configured as a feeding surface 2211, and the second side of the feeding tooth 221 is configured as a smooth curved surface. The end face of the tooth tip of the feeding tooth 221 is connected between the first side and the second side of the feeding tooth 221. Preferably, the end face of the tooth tip of the feeding tooth 221 is an arc surface coaxial with the feeding wheel 2.

[0065] The feeding surface 2211 of the feeding tooth 221 is a plane with a certain extension length along the radial direction of the feeding wheel 2, and the feeding surface 2211 is parallel to the axis of the feeding wheel 2. The saw blade 23 is attached to the feeding surface 2211 and is installed on the feeding tooth 221 by screws or bolts.

[0066] Specifically, the feeding tooth 221 is provided with a first mounting hole, which extends vertically from the middle of the feeding surface 2211, and the saw tooth 23 is provided with a second mounting hole 233 in the middle, which corresponds to the first mounting hole.

[0067] In some possible embodiments, the saw blade 23 is mounted on the feeding tooth 221 by bolts. Specifically, the bolt passes through the second mounting hole 233 and the first mounting hole, and is connected to a nut provided on the second side of the feeding tooth 221 and adapted to the bolt, thereby fixing the saw blade 23 on the feeding surface 2211.

[0068] Preferably, the second side of the feeding tooth 221 is provided with a groove for receiving the nut.

[0069] In some other possible embodiments, the serrated blade 23 is mounted on the feed tooth 221 by a screw. Specifically, the first mounting hole is configured as a screw hole, the internal thread on the inner peripheral wall of the screw hole is adapted to the external thread on the screw, and the screw passes through the second mounting hole 233 on the serrated blade 23 and is tightened in the first mounting hole, thereby fixing the serrated blade 23 on the feed surface 2211.

[0070] In this embodiment, the second mounting hole 233 can be a round hole or an oblong hole. Preferably, the second mounting hole 233 is an oblong hole, with the length direction of the oblong hole being away from the axis of the feed wheel 2. This improves the efficiency of the second mounting hole 233 corresponding to the first mounting hole, which is beneficial for the rapid installation of the saw blade 23. At the same time, the oblong hole design also makes it convenient for the operator to adjust the installation position of the saw blade 23.

[0071] Preferably, in this embodiment, at least two sets of corresponding second mounting holes and first mounting holes are provided between a single saw blade 23 and a single feeding tooth. Preferably, a single saw blade 23 is provided with two second mounting holes, and a single feeding tooth is provided with two first mounting holes that correspond one-to-one with the two second mounting holes. The single saw blade 23 and the single feeding tooth are assembled by two bolts to ensure the stability of the installation of the saw blade 23.

[0072] In this embodiment, the assisting saw tooth 231 corresponds to the side of the feeding surface 2211 away from the axis of the feeding wheel 2. Specifically, the end of the assisting saw tooth 231 is basically flush with the tooth tip of the feeding tooth 221. That is, the end of the assisting saw tooth 231 is on the cylindrical surface where the tooth tip of the feeding tooth 221 is located, or the end of the assisting saw tooth 231 extends beyond the cylindrical surface where the tooth tip of the feeding tooth 221 is located, or the tooth tip of the assisting saw tooth 231 extends to be close to the tooth tip of the feeding tooth 221.

[0073] Preferably, the distance between the end of the assist saw tooth 231 and the tooth end of the feed tooth 221 is less than or equal to 5 mm.

[0074] Preferably, in this embodiment, the end of the assist saw tooth 231 and the tooth end of the material-pulling tooth 221 are on the same cylindrical surface.

[0075] In this embodiment, the assisting saw tooth 231 is disposed on one side of the saw blade 23, which is a plate-like structure with a certain thickness. The side of the assisting saw tooth 231 near the feeding surface 2211 is configured as an inclined surface extending away from the feeding wheel 2 axis and away from the feeding surface 2211. This creates a gap between the assisting saw tooth 231 and the feeding surface 2211, improving the effect of the assisting saw tooth 231 on the Chinese herbal medicine slices and increasing the reliability of feeding.

[0076] The assist saw teeth 231 include a plurality of sharp tooth-like structures 2311 evenly arranged along the length of the saw blade 23.

[0077] Specifically, such as Figure 12 and Figure 13 As shown, the side of the assist saw tooth 231 away from the material feeding surface 2211 is set as a plane parallel to the material feeding surface 2211. This plane is connected to the inclined surface of the assist saw tooth 231 near the material feeding surface 2211, forming the end of the assist saw tooth 231.

[0078] In some specific embodiments, the saw blade 23 includes a saw blade body 232 and an auxiliary saw blade 231, wherein the saw blade body 232 and the auxiliary saw blade 231 are integral parts.

[0079] The assisting saw tooth 231 is disposed at the end of the saw blade body 232. The first side of the assisting saw tooth 231 is coplanar with the first side of the saw blade body 232 and is set as a plane parallel to the material feeding surface 2211. The second side of the assisting saw tooth 231 is set as an inclined surface. The inclined surface extends obliquely from the end of the second side of the saw blade body 232 toward the direction close to the first side of the assisting saw tooth 231. The inclined surface of the second side of the assisting saw tooth 231 intersects with the plane of the first side of the assisting saw tooth 231 to form an edge. A V-shaped groove 2312 is provided on the edge, thereby forming the pointed tooth structure 2311 between two adjacent V-shaped grooves 2312.

[0080] The width of the toothed structure 2311 gradually decreases along the direction away from the axis of the feed wheel 2. Specifically, the left and right sides of the toothed structure 2311 are formed between the groove walls of the two adjacent V-shaped grooves 2312, and the edges where the second side of the self-force serration 231 on the left and right sides of the toothed structure 2311 connects with the first side intersect at a point.

[0081] Preferably, in this embodiment, a support platform 24 is provided on the feeding surface 2211. The support platform 24 protrudes outward from the feeding surface 2211 along the axis of the feeding wheel 2. The side of the support platform 24 away from the axis of the feeding wheel 2 is set as a support plane perpendicular to the feeding surface 2211. The support plane is used to limit the saw blade 23 on the side near the axis of the feeding wheel 2.

[0082] The support platform 24 can improve the limiting effect on the saw blade 23, thereby enabling precise positioning and rapid installation of the saw blade 23. At the same time, it can improve the stability of the saw blade 23 during operation.

[0083] In this embodiment, the feeding wheel 2 rotates toward the side where the feeding surface 2211 is located. During the rotation of the feeding wheel 2, the feeding teeth 221 located in the same row push the Chinese herbal medicine pieces in sequence, so as to adapt to the special shape of the Chinese herbal medicine pieces, avoid the situation of the medicines tangling together, and ensure the realization of the function of the feeding wheel 2.

[0084] Specifically, the unique characteristic of Chinese herbal medicine slices is that they vary in shape and are irregular.

[0085] like Figure 11 As shown in the diagram, during operation, the feeding teeth 221 in the same row feed material sequentially along the arrangement direction from the first end 2-1 of the feeding wheel to the second end 2-2 of the feeding wheel. That is, the feeding teeth 221 closest to the first end 2-1 of the feeding wheel feed material first.

[0086] In this embodiment, the support platform 24 is correspondingly disposed at one end of the feeding surface 2211 near the first end 2-1 of the feeding wheel. Preferably, the width of the support platform 24 gradually decreases along the direction near the second end 2-2 of the feeding wheel, that is, the width of the support plane of the support platform 24 gradually decreases along the direction near the second end 2-2 of the feeding wheel.

[0087] Preferably, in this embodiment, the feeding surface 2211 extends radially along the feeding wheel 2.

[0088] In this embodiment, the saw blades 23 are installed on the feeding surfaces 2211 of each feeding tooth 221 of the feeding wheel 2.

[0089] In some possible embodiments, the feeding wheel 2 is composed of a central shaft and multiple discs. Specifically, the feeding wheel 2 includes a central shaft and multiple discs mounted on the central shaft. Each disc has the same number of feeding teeth 221, which are evenly arranged around the circumference of the discs. The feeding teeth 221 on the multiple discs form multiple rows of feeding teeth 221 evenly distributed around the circumference of the feeding wheel 2.

[0090] In this embodiment, the wheel is sleeved on the central shaft, and a set screw is threaded onto the wheel. The set screw extends radially along the wheel, and one end of the set screw near the axis of the wheel presses against the wheel shaft, thus fixing the wheel and the wheel shaft together.

[0091] In this embodiment, the axial end faces of two adjacent discs are in contact with each other.

[0092] In some other possible embodiments, the feeding wheel 2 includes a main body and a feeding part 22 integrally connected. The main body is cylindrical, and the feeding part 22 protrudes outward from the outer peripheral wall of the main body. It is an oblique convex ridge extending along the axial direction of the main body, and its extension direction forms an acute angle with the axis of the main body. The two ends of the feeding part 22 are flush with the two ends of the main body. A plurality of feeding teeth 221 are provided on the first side of the feeding part 22, and the plurality of feeding teeth 221 are arranged in a stepped continuous manner along the extension direction of the feeding part 22.

[0093] Specifically, the feeding wheel 2 is designed as a single unit, so only the feeding wheel 2 needs to be installed as a whole, without the need for multiple wheel discs to be spliced ​​together, which facilitates the installation of the feeding wheel 2. Moreover, the shape of the feeding part 22 of the feeding wheel 2, which is a single unit, will not be affected by installation errors, thereby ensuring the dispensing accuracy of Chinese herbal medicine pieces. At the same time, there are no assembly gaps on the feeding wheel 2, which can prevent Chinese herbal medicine pieces from getting stuck on the feeding wheel 2 and prevent the accumulation of medicinal ash on the feeding wheel 2.

[0094] In this embodiment, a plurality of feeding teeth 221 arranged in a stepped continuous manner are disposed on the first side of the feeding part 22, and the second side 22-1 of the feeding part is configured as a curved surface that smoothly transitions with the outer peripheral wall of the main body. Specifically, the second side 22-1 of the feeding part is a torsional curved surface.

[0095] In this embodiment, the feeding teeth 221 on the feeding section 22 have the same shape.

[0096] Specifically, the feeding part 22 can be understood as including a feeding body and feeding teeth 221. The feeding teeth 221 protrude circumferentially from the first side of the feeding body and extend axially along the feeding wheel 2. The thickness of the feeding teeth 221 gradually increases along the extension direction from the first end 2-1 of the feeding wheel to the second end 2-2 of the feeding wheel, thus forming a stepped feeding tooth 221. The "thickness of the feeding tooth 221" refers to the dimension of the feeding tooth 221 extending circumferentially along the body.

[0097] The feeding teeth 221 on the first side of the feeding body constitute the first side of the feeding part 22, and the second side of the feeding body is a smooth curved surface, which constitutes the second side 22-1 of the feeding part.

[0098] In this embodiment, the feeding part 22 is provided with a plurality of feeding parts arranged at intervals along the circumference of the main body, and the spatial extension trajectory of a single feeding wheel 2 is a spiral line segment.

[0099] In some specific embodiments, the feeding portion 22 can be formed by cutting an oblique convex ridge structure. The spatial extension trajectory of the oblique convex ridge structure is a spiral segment, and the width of the oblique convex ridge structure gradually decreases along the axis away from the main body. Cutting is performed from the first side of the oblique convex ridge structure to form the feeding tooth 221. After cutting, the remaining part of the oblique convex ridge except for the feeding tooth 221 constitutes the feeding body.

[0100] Specifically, such as Figure 11 and Figure 12 As shown, the feeding tooth 221 includes a feeding surface 2211, a first connecting surface 2212, and a second connecting surface 2213. The feeding surface 2211 extends in a direction parallel to the axis of the main body. The first connecting surface 2212 extends circumferentially along the main body and connects to the side of the feeding surface 2211 away from the axis of the main body. The second connecting surface 2213 extends in a direction perpendicular to the axis of the main body and connects between the feeding surface 2211 and the first connecting surface 2212.

[0101] In this embodiment, the first connecting surface 2212 extends circumferentially along the main body and is coplanar with the side of the feeding body away from the axis of the main body. The width of the first connecting surface 2212 gradually increases along the direction close to the second end 2-2 of the feeding wheel. Preferably, the unfolded surface of the first connecting surface 2212 is a right triangle or a right trapezoid.

[0102] The second connecting surface 2213 extends radially along the main body and is disposed on the side of the feeding tooth 221 facing the second end 2-2 of the feeding wheel. The feeding surface 2211 of another feeding tooth 221 adjacent to the feeding tooth 221 and located near the second end 2-2 of the feeding wheel extends vertically from the second connecting surface 2213 of the feeding tooth 221.

[0103] In this embodiment, the extending direction of the feeding surface 2211 is perpendicular to the extending direction of the second connecting surface 2213.

[0104] In this embodiment, the end of the feeding tooth 221 near the first end 2-1 of the feeding wheel is flush with the first end 2-1 of the feeding wheel, and the end of the feeding tooth 221 near the second end 2-2 of the feeding wheel is flush with the second end 2-2 of the feeding wheel. That is, the sum of the extension lengths of the multiple feeding teeth 221 on the same feeding part 22 in the axial direction of the main body is equal to the axial length of the main body.

[0105] like Figures 1 to 13 As shown in the figure, this embodiment also provides a traditional Chinese medicine decoction piece dispensing mechanism, which includes a material hopper 1, a medicine dispensing module and a bridge breaking module 6.

[0106] Specifically, the hopper 1 is used to hold Chinese herbal medicine pieces, and the dispensing module is set near the outlet 1-2 of the hopper, including the dispensing wheel of the Chinese herbal medicine dispensing mechanism, the medicine blocking and flow limiting mechanism 3 that cooperates with the dispensing wheel 2, and the drive mechanism 4 for driving the dispensing wheel 2 to rotate.

[0107] The feeding wheel 2 of the dispensing module and the medicine blocking and flow limiting mechanism 3 block the outlet 1-2 of the hopper. The driving mechanism 4 is connected to the feeding wheel 2 and is used to drive the feeding wheel 2 to rotate toward the side where the feeding surface 2211 is located. The output amount of Chinese herbal medicine pieces is adjusted by controlling the rotation of the feeding wheel 2.

[0108] Preferably, in this embodiment, the feeding teeth 221 are provided in multiple rows evenly distributed along the circumference of the feeding wheel 2, and the angle of extension of a single row of feeding teeth 221 in the circumference of the feeding wheel 2 is 360° divided by the number of rows of feeding teeth 221.

[0109] With the above settings, when the last feeding tooth 221 of the previous row of feeding teeth 221 finishes feeding, the first feeding tooth 221 of the next row of feeding teeth 221 adjacent to that row of feeding teeth 221 rotates to the working position. That is, during the rotation of the feeding wheel 2, multiple feeding teeth 221 in the same row can feed continuously, and the last feeding tooth 221 of a row of feeding teeth 221 and the first feeding tooth 221 of a row of feeding teeth 221 adjacent to that row of feeding teeth 221 can feed continuously.

[0110] The “first feeding tooth 221” is the feeding tooth 221 in the same row that is close to the first end 2-1 of the feeding wheel, and the “last feeding tooth 221” is the feeding tooth 221 in the same row that is close to the second end 2-2 of the feeding wheel.

[0111] This ensures the continuity of the action of the feeding wheel 2, which is beneficial to improving the dispensing accuracy of the traditional Chinese medicine decoction piece dispensing mechanism.

[0112] Preferably, in this embodiment, all the feeding teeth 221 located on the same feeding wheel 2 have the same shape.

[0113] In this embodiment, the feeding wheel 2 is coaxially provided with a mounting hole 211. The radial cross section of the mounting hole 211 is a regular polygon, which is used to limit the circumferential movement of the drive shaft 5 of the traditional Chinese medicine dispensing mechanism.

[0114] Specifically, the mounting hole 211 extends through the axial direction of the feed wheel 2 and is coaxial with the feed wheel 2. The drive shaft 5 passes through the feed wheel 2 through the mounting hole 211, and both ends of the drive shaft 5 extend at least partially outside the mounting hole 211 for assembly. The drive shaft 5 is coaxial with the feed wheel 2, and at least a portion of the shape of the drive shaft 5 is the same as the shape of the mounting hole 211.

[0115] The drive mechanism 4 is connected to the drive shaft 5 via a transmission.

[0116] In some specific embodiments, the drive mechanism 4 includes a drive motor 40, a drive wheel 41, and a driven wheel 42, with the drive wheel 41 mounted on the working end of the drive motor 40.

[0117] The drive motor 40 is mounted on the outside of the silo wall of the silo 1 via the motor bracket 124. The working end of the drive motor 40 is parallel to the drive shaft 5. One end of the drive shaft 5 corresponding to the working end of the drive motor extends through the silo wall of the silo 1 to the outside of the silo 1. The driven wheel 42 is mounted on the end of the drive shaft 5.

[0118] The driving wheel 41 and the driven wheel 42 can be driven by gears, belts, or chains.

[0119] Specifically, in this embodiment, both the driven wheel 42 and the driving wheel 41 are configured as belt pulleys, and the drive mechanism 4 also includes a transmission belt 43 disposed between the two.

[0120] Preferably, in this embodiment, a limiting groove is provided on the pulley, and the limiting groove is located on the outer peripheral wall of the pulley. The width of the limiting groove is adapted to the width of the transmission belt 43. Transmission teeth are provided on the bottom of the limiting groove, extending axially along the pulley, and a plurality of transmission teeth are evenly arranged circumferentially along the pulley. The transmission teeth are used to cooperate with the transmission belt 43 to ensure the transmission stability between the transmission belt 43 and the pulley and to prevent slippage.

[0121] Preferably, in this embodiment, the drive motor 40 can be a planetary gear reducer motor.

[0122] In this embodiment, the drug blocking and flow limiting mechanism 3 includes a first blocking device 31 and a second blocking device 32. Along the rotation direction of the feeding wheel 2, the first blocking device 31 is located upstream of the second blocking device 32. Both the first blocking device 31 and the second blocking device 32 are installed on the wall of the hopper 1 and are in contact with the circumferential surface of the feeding wheel 2 to seal the gap between the feeding wheel 2 and the wall of the hopper 1.

[0123] like Figures 1 to 8 As shown, in some possible embodiments, the dispensing module may include multiple feeding wheels 2, and a set of driving mechanisms 4 is provided for each feeding wheel 2.

[0124] The number of rows of feeding teeth 221 on the feeding wheel 2 and the number of feeding teeth 221 in a single row can be the same or different. Therefore, by controlling the rotation of different numbers and types of feeding wheels 2, the dispensing accuracy of the dispensing mechanism can be improved.

[0125] Preferably, in this embodiment, the feeding wheel 2 includes a first feeding wheel 201 and a second feeding wheel 202 arranged side by side in the horizontal direction. The first feeding wheel 201 has m rows of feeding teeth 221 evenly distributed circumferentially along its circumference. Each row of feeding teeth 221 extends circumferentially at an angle of (360 / m)°, and each feeding tooth 221 extends axially for a length of K. The second feeding wheel 202 has n rows of feeding teeth 221 evenly distributed circumferentially along its circumference. Each row of feeding teeth 221 extends circumferentially for a length of (360 / n)°, and each feeding tooth 221 extends axially for a length of L. The axial lengths of the first feeding wheel 201 and the second feeding wheel 202 are equal, and m is greater than n, and / or K is less than L.

[0126] like Figure 10As shown, in some other possible embodiments, the dispensing module includes a feeding wheel 2 and is equipped with a set of drive mechanisms 4 to drive it.

[0127] In this embodiment, the feeding wheel is provided with a row of feeding teeth evenly distributed circumferentially. The angle of extension of a single row of feeding teeth in the circumferential direction of the feeding wheel is (360 / a)°, and the extension length of each feeding tooth in the axial direction of the feeding wheel is F.

[0128] In some preferred embodiments, when the discharge module has only one feeding wheel, in order to ensure the adjustment accuracy, a is set to be less than m, and / or F is set to be less than L.

[0129] Preferably, in this embodiment, 'a' equals half the sum of 'm' and 'n', and 'F' is less than or equal to 'K'. This ensures both the accuracy and efficiency of the dispensing process.

[0130] Specifically, in this embodiment, the hopper 1 includes a first extension section 11, a second extension section 12 and a third extension section 13 connected sequentially from top to bottom. The first extension section 11 is used to accommodate Chinese herbal medicine pieces, the second extension section 12 is used to install a medicine dispensing module, and the third extension section 13 is used to output Chinese herbal medicine pieces.

[0131] The second extension segment 12 extends vertically downward from the outlet of the first extension segment 11, and the cross-sectional area of ​​the second extension segment 12 is the same everywhere. The third extension segment 13 extends vertically downward from the outlet of the second extension segment 12, and the cross-sectional area of ​​the third extension segment 13 gradually decreases along the downward extension direction, which facilitates the collection of the output Chinese herbal medicine slices.

[0132] In this embodiment, the drive shaft 5 of the feeding wheel 2 is mounted between two opposing bin walls of the second extension section 12 via a mounting bearing.

[0133] In this embodiment, the feeding wheel 2 is installed between the two bin walls of the second extension section 12 via the drive shaft 5, and the two ends of the feeding wheel 2 are respectively attached to the inner sides of the two bin walls of the second extension section 12.

[0134] Specifically, mounting bearings are respectively installed on the two bin walls of the second extension section 12. The mounting bearings on the two bin walls of the second extension section 12 correspond one-to-one and form a set. The set of mounting bearings on the two bin walls of the second extension section 12 is coaxial and is used to support the drive shaft of one feeding wheel. The two ends of the drive shaft 5 are respectively connected to the two mounting bearings in the same set.

[0135] In some specific embodiments, the second extension 12 has an opening in its wall and a radial protrusion at the end of the bearing mounting section. The bearing is inserted into the opening from the inside of the wall of the second extension 12, and the radial protrusion fits against the inside of the wall of the second extension 12.

[0136] The radial protrusion corresponds to the middle of the axial end face of the feeding wheel 2, and the inner side of the bin wall of the second extension section 12 and / or the axial end of the feeding wheel 2 are provided with receiving grooves for accommodating the radial protrusion. Thus, it can be ensured that the end of the main body fits against the inner side of the bin wall of the second extension section 12.

[0137] In some preferred embodiments, a partition 123 is provided on the inner side of the bin wall of the second extension section 12. The thickness of the partition 123 is the same as the axial dimension of the radial protrusion. A clearance opening is provided on the partition 123 corresponding to the radial protrusion. The inner diameter of the clearance opening is greater than or equal to the outer diameter of the radial protrusion and smaller than the diameter of the circumference of the end of the feeding tooth 221 near the axis of the feeding wheel 2.

[0138] In this embodiment, the inner side of the partition plate is in contact with the axial end face of the feeding wheel.

[0139] The above configuration can prevent a large gap from forming between the axial end face of the feeding wheel and the bin wall of the second extension section due to the bearing installation.

[0140] In this embodiment, the size of the partition is the same as the size of the inner side of the bin wall used to house the second extension 12 for mounting the bearing.

[0141] The partition is attached to the silo wall of the second extension section by bolts or screws.

[0142] like Figure 8 As shown, in some specific embodiments, the feeding wheel includes a first feeding wheel and a second feeding wheel arranged side by side in a horizontal direction. The first feeding wheel 201 and the second feeding wheel 202 are arranged side by side, and their axes are parallel to each other and extend in a horizontal direction.

[0143] Specifically, in this embodiment, during the dispensing process, the first feeding wheel 201 and the second feeding wheel 202 rotate in opposite directions.

[0144] In this embodiment, the first feeding wheel 201 and the second feeding wheel 202 are spaced apart, and two second material blocking devices 32 that cooperate with the first feeding wheel 201 and the second feeding wheel 202 are respectively arranged between the first feeding wheel 201 and the second feeding wheel 202, and are installed in the hopper 1 through an inverted V-shaped bracket 14.

[0145] Preferably, the inverted V-shaped bracket 14 is fixed to the wall of the silo 1.

[0146] The first material blocking device 31, which cooperates with the first material feeding wheel 201, is located on the side of the first material feeding wheel 201 away from the second material feeding wheel 202. The first material blocking device 31, which cooperates with the second material feeding wheel 202, is located on the side of the second material feeding wheel 202 away from the first material feeding wheel 201.

[0147] like Figure 10 As shown, in some other specific embodiments, a single feeding wheel is provided, the axis of which extends horizontally. A first and a second material-blocking device, which cooperate with the feeding wheel, are respectively fixed to the walls of opposite sides of the hopper.

[0148] Preferably, the first material blocking device is fixedly installed on the bin wall of the second extension section, the second material blocking device is fixedly installed on the bin wall of the first extension section near one end of the second extension section, and the brush part of the second material blocking device extends downward into the second extension section and abuts against the feeding wheel.

[0149] In this embodiment, both the first material blocking device 31 and the second material blocking device 32 include a mounting part 3-2 and a brush part 3-1. The mounting part 3-2 includes a mounting plate and a mounting groove, which are integrated. The mounting plate is used for assembly with the hopper 1, and the mounting groove is used for mounting the brush part 3-1. In this embodiment, one end of the brush part 3-1 is fixed in the mounting groove.

[0150] The mounting plate of the first baffle device 31 is attached to the inner side of the bin wall of the second extension section 12 and fixed by bolts or screws. Specifically, the second extension section 12 includes a pair of oppositely arranged third bin walls 121 and a pair of oppositely arranged fourth bin walls 122. The feeding wheel is mounted on the oppositely arranged third bin walls 121 by mounting bearings and drive shaft 5.

[0151] When the feeding wheel includes a first feeding wheel and a second feeding wheel, the mounting parts 3-2 of the two first material blocking devices 31, which respectively cooperate with the first feeding wheel and the second feeding wheel, are respectively mounted on the two oppositely arranged fourth bin walls 122 by screws or bolts; the mounting plate of the second material blocking device 32 is attached to the side wall of the inverted V-shaped bracket 14 and fixed by bolts or screws. The inverted V-shaped bracket 14 can be fixed in the bin 1 by welding.

[0152] like Figure 10 As shown, when only one feeding wheel is provided, the mounting part 3-2 of the first material blocking device 31 that cooperates with the feeding wheel is mounted on the fourth compartment wall on one side of the feeding wheel by screws or bolts, and the mounting part of the second material blocking device that cooperates with the feeding wheel is mounted on the other side of the feeding wheel by screws or bolts, and is installed at the lower end of the fifth compartment wall 113 at the bottom of the first extension section.

[0153] In this embodiment, the first extension section and the second extension section of the hopper are connected as one unit, and the third extension section is set separately and assembled at the lower end of the second extension section.

[0154] In some specific embodiments, a mounting notch is provided on the third compartment wall on the first side of the second extension section. The mounting notch is U-shaped and faces downwards. An assembly part 125 is detachably mounted at the mounting notch. Both ends of the drive shaft are respectively mounted on the assembly part 125 and the third compartment wall on the second side of the second extension section via mounting bearings. The second side of the second extension section is arranged opposite to the first side of the second extension section. The end of the drive shaft extends from the first side of the second extension section to the outside of the second extension section and is connected to the drive mechanism for transmission.

[0155] In this embodiment, the assembly part 125 includes a first plate part 1251 corresponding to the mounting notch, a second plate part 1252 extending from both ends of the first plate part 1251, and a third plate part 1253 fixed to the outside of the first plate part 1251 and attached to the outside of the third compartment wall of the first side of the second extension above the mounting notch.

[0156] The two second plate portions 1252 extend to the outside of the two fourth compartment walls 122 of the second extension section respectively, and are bolted to the fourth compartment walls 122 of the second extension section.

[0157] Two third plate portions 1253 are spaced apart on the upper side of the first plate portion 1251 and can be welded and fixed to the first plate portion 1251. The upper end of the third plate portion 1253 extends beyond the third plate portion 1253 and fits against the third compartment wall on the first side of the second extension section above the mounting notch.

[0158] The size of the partition is the same as the size of the inner side of the third compartment wall on the first side of the second extension. The partition is assembled onto the compartment wall of the second extension by bolts or screws.

[0159] Preferably, the bolts for mounting the partition pass through the third plate portion 1253, the third compartment wall on the first side of the second extension above the mounting notch, and the partition is connected to the nut.

[0160] The above configuration facilitates the installation of the cutting tool. Specifically, the partition on the second side of the second extension section can be installed on the third chamber wall on the second side of the second extension section first, and the partition on the first side of the second extension section can be placed in the set position. Then, the mounting bearing on the second side of the second extension section, the drive shaft, and the mounting bearing on the first side of the second extension section can be installed in sequence. When installing the drive shaft, the drive shaft passes through the cutting tool and is circumferentially limited and fitted therewith. Finally, the assembly part 125 is installed on the second extension section. During the installation process, the assembly part 125 and the partition on the second side of the second extension section are fixed on the second extension section by bolts.

[0161] The third extension is detachably mounted on the lower end of the second extension and secured with bolts.

[0162] The upper end of the third extension section has an ear plate 131 extending upward. The four ear plates 131 extend to the outer side of the two third compartment walls and the outer side of the two fourth compartment walls, respectively, and are bolted to the third compartment walls and the fourth compartment walls.

[0163] Preferred, such as Figure 1 , Figure 2 , Figure 4 and Figure 9 As shown in this embodiment, the motor bracket is plate-shaped, and the side of the motor bracket is provided with a bent part for connecting with the hopper. The motor bracket is installed between the first extension section and the second extension section.

[0164] Specifically, the motor bracket is installed at the bend between the first compartment wall 111 of the first extension section and the fourth compartment wall of the second extension section, and / or, the motor bracket is installed at the bend between the fifth compartment wall 113 of the first extension section and the fourth compartment wall of the second extension section.

[0165] In this embodiment, the motor bracket includes a first edge for fitting against the first compartment wall 111 or the fifth compartment wall of the first extension section, and a second edge for fitting against the fourth compartment wall of the second extension section. The first edge and the second edge are respectively provided with bent portions 1241 extending perpendicularly relative to the motor bracket. The bent portions 1241 on the first edge fit against the first compartment wall 111 or the fifth compartment wall and are fixedly connected to the first compartment wall 111 or the fifth compartment wall by screws or bolts. The bent portions 1241 on the second edge fit against the fourth compartment wall and are fixedly connected to the fourth compartment wall by screws or bolts.

[0166] Specifically, for a dispensing mechanism with only one feeding wheel, the drive motor connected to the feeding wheel can be installed between the first compartment wall 111 and the corresponding fourth compartment wall via a motor bracket, or it can be installed between the fifth compartment wall and the fourth compartment wall on the other side via a motor bracket.

[0167] For the dispensing mechanism equipped with the first feeding wheel and the second feeding wheel, two drive motors that are respectively connected to the first feeding wheel and the second feeding wheel are respectively installed between the first bin wall 111 and the fourth bin wall, and between the fifth bin wall and the fourth bin wall on the other side through motor brackets.

[0168] Preferably, in this embodiment, the bent portion on the second edge of the motor bracket fits into the second plate portion 1252 of the assembly portion, and the screws or bolts for installing the motor bracket pass through the bent portion, the second plate portion and the fourth compartment wall.

[0169] By connecting the bent portion on the second edge of the motor bracket to the outside of the second plate, the number of connecting parts such as screws or bolts can be reduced, and the overall installation strength can be guaranteed. The second plate serves to strengthen the "motor bracket connection position" and can prevent the silo wall of the second extension section from deforming.

[0170] Preferred, such as Figure 7 As shown, a C-shaped notch is provided on the side of the second plate portion 1252 away from the first plate portion, and a cylindrical protrusion that mates with the C-shaped notch is provided on the fourth compartment wall. When the assembly portion is installed, the C-shaped notch is fitted onto the cylindrical protrusion to achieve pre-positioning between the assembly portion and the second extension section, which is beneficial to improving the installation efficiency and positioning accuracy of the assembly portion.

[0171] A bridge-breaking module 6 is provided on the silo 1. The bridge-breaking module 6 includes a bridge-breaking rod 61, a bridge-breaking motor 62, and a transmission assembly 63. The bridge-breaking rod 61 is rotatably disposed between two opposite silo walls of the silo 1, and multiple parallel bridge-breaking rods 61 are provided. The bridge-breaking motor 62 is disposed on the outside of the silo wall and is connected to one bridge-breaking rod 61 for transmission. The transmission assembly 63 is disposed on the outside of the silo wall and is used to drive each bridge-breaking rod 61 to rotate synchronously.

[0172] Specifically, the bridge-breaking rod 61 includes a main rod 611 that penetrates the silo 1 and is mounted on two opposite walls of the silo 1 via bearings, and a support rod 612 that is fixed on the main rod 611 and extends in a direction perpendicular to the main rod 611. The support rod 612 is provided with a plurality of rods spaced apart along the length direction of the main rod 611. The main rod 611 is driven by the bridge-breaking motor 62 or by the transmission assembly 63, which drives the support rod 612 to rotate, thereby agitating the Chinese herbal medicine pieces in the silo 1.

[0173] In this embodiment, the support rods 612 are arranged in a plurality of spaced intervals along the axial direction of the main rod 611, and the extension directions of two adjacent support rods 612 are perpendicular to each other.

[0174] In this embodiment, the bridge-breaking module 6 is installed on the first extension section 11 of the hopper 1.

[0175] Specifically, the first extension section 11 of the hopper 1 includes a first hopper wall 111 and a second hopper wall 112 that are parallel to each other. Along the downward extension direction, the first hopper wall 111 and the second hopper wall 112 extend obliquely to the side where the second hopper wall 112 is located. Multiple bridge-breaking rods 61 are vertically arranged between the first hopper wall 111 and the second hopper wall 112. The second end of each bridge-breaking rod 61 extends to the outside of the second hopper wall 112. The transmission assembly 63 includes multiple transmission wheels 631 installed on the second end of each bridge-breaking rod 61, and a synchronous belt 632 sleeved on the transmission wheels 631. The bridge-breaking motor 62 is arranged outside the first hopper wall 111 and is connected to the first end of a bridge-breaking rod 61.

[0176] During operation, the bridge-breaking motor 62 drives one bridge-breaking rod 61 connected to it to rotate. This bridge-breaking rod 61, via the transmission assembly 63, drives the other bridge-breaking rods 61 to rotate synchronously. Specifically, a synchronous belt 632 is fitted onto all the transmission pulleys 631. The rotation of the transmission pulley 631 on the bridge-breaking rod 61 connected to the bridge-breaking motor 62 drives the other transmission pulleys 631 to rotate synchronously via the synchronous belt 632, and the other transmission pulleys 631 drive the corresponding bridge-breaking rods 61 to rotate.

[0177] Of course, multiple synchronous pulleys can also be driven by multiple synchronous belts 632.

[0178] In some possible embodiments, two bridge-breaking rods 61 are provided, which are arranged side by side between the first and second compartment walls, and the drive wheels on the two bridge-breaking rods are connected by a synchronous belt 632.

[0179] Preferably, the two bridge-breaking rods 61 are arranged sequentially from top to bottom, that is, one bridge-breaking rod is positioned directly above the other bridge-breaking rod.

[0180] In some other possible embodiments, three bridge-breaking rods 61 are provided. Two drive wheels 631 can be provided on one of the bridge-breaking rods 61. The two drive wheels 631 are arranged at intervals along the axial direction of the bridge-breaking rod 61. One of the two drive wheels 631 is connected to the drive wheel 631 on another bridge-breaking rod 61 through a synchronous belt 632. The other of the two drive wheels 631 is connected to the drive wheel 631 on yet another bridge-breaking rod 61 through a synchronous belt 632.

[0181] In this embodiment, the bridge-breaking motor can specifically be a turbine-reduced stepper motor.

[0182] In this embodiment, by setting the first bin wall 111 to extend downwards, the first bin wall 111 and the second bin wall 112 extend obliquely to the side where the second bin wall 112 is located, that is, the first bin wall is located below the second bin wall. The second bin wall 112 is parallel to the first bin wall 111, so that the first extension section 11 of the hopper 1 forms a downwardly oblique extension section. Arranging the bridge breaking module 6 here can improve the stirring effect of the bridge breaking rod 61 on the Chinese herbal medicine pieces.

[0183] In this embodiment, the lower end of the second compartment wall 112 slopes downward toward the side closer to the first compartment wall 111, forming a fifth compartment wall 113. The lower end of the fifth compartment wall 113 extends to the same horizontal level as the lower end of the first compartment wall 111. This facilitates the collection of Chinese herbal medicine pieces stored in the first extension section 11 toward the entrance of the second extension section 12.

[0184] Preferably, the lower end of the second compartment wall 112 first bends vertically downward and extends, and then tilts towards the side closer to the first compartment wall 111.

[0185] Preferably, in this embodiment, the bridge-breaking rods 61 include a first bridge-breaking rod 61-1, a second bridge-breaking rod 61-2, and a third bridge-breaking rod 61-3 arranged in a triangular pattern. These three rods are arranged sequentially from top to bottom on the same horizontal plane, with the projection of the first bridge-breaking rod 61-1 located between the projections of the second bridge-breaking rod 61-2 and the third bridge-breaking rod 61-3. Thus, the synergistic effect of the three bridge-breaking rods 61 ensures effective agitation of all areas within the first extension section 11 of the silo 1, preventing the accumulation of medicinal herb slices within the silo 1.

[0186] In this embodiment, for a dispensing mechanism with only one feeding wheel, its bridge-breaking module is preferably equipped with two bridge-breaking rods; for a dispensing mechanism with two feeding wheels, its bridge-breaking module is preferably equipped with three bridge-breaking rods.

[0187] In this embodiment, the upper end of the first extension section 11 forms the inlet 1-1 of the silo, and the lower end of the third extension section 13 forms the outlet 1-2 of the silo. Specifically, the upper end of the second silo wall 112 is higher than the upper end of the first silo wall 111, and the upper end of the second silo wall 112 extends horizontally towards the side close to the first silo wall 111, forming the inlet 1-1 of the silo with the upper end of the first silo wall 111.

[0188] In this embodiment, the other wall of the first extension section 11 is connected between the first wall 111 and the second wall 112 and the third wall 121, forming the first extension section 11 with open ends.

[0189] The Chinese herbal medicine pieces are put into the silo through the inlet 1-1. Under the blocking action of the feeding wheel 2 and the medicine flow limiting mechanism 3, the Chinese herbal medicine pieces are stored in the first extension section 11 of the silo 1.

[0190] During the dispensing process, the drive mechanism 4 drives the second feeding wheel 202 to rotate, or the drive mechanism 4 drives the first feeding wheel 201 and the second feeding wheel 202 to rotate simultaneously for coarse dispensing. When the amount of Chinese herbal medicine pieces output is close to the expected amount of medicine, the second feeding wheel 202 stops rotating, and the drive mechanism 4 drives the first feeding wheel 201 to rotate for fine dispensing, ensuring the speed and accuracy of dispensing.

[0191] During the dispensing process, the bridge-breaking motor 62 works continuously or intermittently to agitate the Chinese herbal medicine pieces in the silo 1, preventing blockage and ensuring a stable dispensing process.

[0192] In some specific embodiments, a balance monitoring unit is installed inside the silo. This unit can be a photoelectric sensor. When the photoelectric sensor detects that there are insufficient Chinese herbal medicine pieces in the silo, it sends a feedback to the control unit, which then controls the alarm unit to issue an alarm message. The alarm message can be an indicator light or a notification sound.

[0193] In some specific embodiments, a weighing hopper can be installed below the outlet of the silo. The weighing hopper includes a weighing box integrally mounted on a weighing sensor, a weighing gate, and an opening mechanism. The weighing gate is rotatably mounted on the bottom of the weighing box and its opening and closing are controlled by the opening mechanism. The weighing sensor is used to weigh the weight of the Chinese herbal medicine pieces entering the weighing box and feeds back the weighing information to the drive mechanism 4.

[0194] In some possible embodiments, the herbal medicine dispensing mechanism includes a control unit, which is communicatively connected to a weighing sensor, a drive mechanism, and a bridge-breaking motor. During the dispensing process, the control unit controls the drive mechanism and the bridge-breaking motor to operate, and receives weighing information from the weighing sensor in real time, controlling the rotational speed of the drive mechanism based on the weighing information. When the weight of the herbal medicine pieces in the weighing hopper reaches the required weight in the dispensing information, the drive mechanism 4 and the bridge-breaking motor stop operating.
