In addition, the terms "first", "second", and "third" are only used for descriptive purposes and should not be construed as indicating or implying relative importance.

[0069] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0070] The inventors referred to the prior art CN201420831067.5, a medicine counting device for an automatic medicine sub-packaging machine, and CN201520943275.9, a medicine cartridge for a medicine sub-packaging machine applied to a medicine dispensing machine, and found that the existing medicine cartridges for sub-packaging machines only have the functions of medicine discharging and tablet counting, and cannot cope with the situation of requiring half tablets of medicine, which cannot meet the expectations of the inventors. Through further research, it was found that in the case of requiring half tablets of medicine, the tablets need to be cut in advance and placed in a medicine cartridge customized according to the shape of half tablets. However, because the half tablets have edges and corners, there are still problems with smooth dropping. Moreover, the surface film of the cut tablets is damaged, and powder will continue to drop, which will not only cause waste but also be inconvenient for long-term storage. To solve this problem, the inventors tried to improve the shape of the rotating core of the medicine cartridge and add a vibration damping mechanism, but the effect was not ideal. During the research process, it was unexpectedly found that cutting the tablets when half tablets of medicine are needed is more convenient for storing the tablets and can also minimize the dropping of medicine powder to the greatest extent.

[0071] Based on this, an embodiment of the present invention provides an automatic half-tablet cutting medicine cartridge assembly applied to a sub-packaging machine, which will be described in detail below.

[0072] An embodiment of the present invention provides an automatic half-tablet cutting medicine cartridge assembly applied to a sub-packaging machine. Referring to Figures 1 - 7 as shown, it includes a motor base 200 and a half-tablet cutting medicine cartridge 100;

[0073] The half-tablet cutting medicine cartridge includes a rotating die core 2, a main housing 1, a blade 3, and a medicine discharging port component 4;

[0074] The rotating die core 2 is arranged inside the main housing 1;

[0075] The top of the rotating die core 2 is conical;

[0076] The side wall of the rotating die core 2 is provided with a first annular groove 211 and a plurality of vertical grooves 213 distributed circumferentially, and the plurality of vertical grooves 213 are respectively communicated with the first annular groove 211;

[0077] A tablet channel is formed between each vertical groove 213 and the inner wall of the main housing 1;

[0078] The blade 3 is fixed to the outer wall of the main housing 1, and the cutting edge side of the blade 3 extends into the main housing 1 and is located in the first annular groove 211;

[0079] The medicine discharging port component 4 is arranged inside the main housing 1 and is located below the blade 3;

[0080] The motor base 200 includes a base body 205, a motor 201, and a dust collection box 202 arranged on the base body 205;

[0081] The lower part of the rotating die core 2 is in driving connection with the output shaft 2011 of the motor 201;

[0082] The dust collection box 202 faces the medicine outlet component 4.

[0083] In the embodiment of the present invention, the width of the vertical groove is designed to accommodate one tablet. After a sufficient amount of tablets are placed in the main housing 1, the tablets will slide down to the lower side of the rotating die core 2 under the action of gravity and enter the tablet channels to be vertically arranged. By driving the rotating die core 2 to rotate through the motor 201, when the vertical groove 213 containing the tablets rotates to the position where the blade 3 is located, the blade 3 will cut the tablet into two half tablets, and the cut half tablets will fall out from the medicine outlet, thus realizing the instant cutting and taking of the tablets.

[0084] Specifically, referring to Figures 1 - 7 As shown, the main housing 1 includes a medicine cup 11, a mounting cylinder 12 and a mounting base 13 which are connected up and down in sequence. The medicine cup 11 is used for storing tablets; the rotating die core 2 includes a rotor 21 and a transmission shaft 22 which are connected up and down. The transmission shaft 22 is inserted into the mounting base 13 and can rotate relative to the mounting base 13. The rotor 21 is located inside the mounting cylinder 12 and can rotate synchronously driven by the transmission shaft 22, and the bottom end of the rotor 21 abuts against the upper surface of the mounting base 13. The first annular groove 211 and a plurality of vertical grooves 213 are arranged on the side wall of the rotor 21. A tablet channel is formed between each vertical groove 213 and the inner wall of the mounting cylinder 12. Since the top of the rotor 21 is conical, the tablets will slide down under the action of gravity and enter the tablet channels to be vertically arranged. The back side of the blade 3 is fixed above the mounting base 13, and the cutting edge side extends into the mounting cylinder 12, and the vertical distance between the blade 3 and the mounting base 13 is the radius of the stored tablets, so as to ensure that the tablets can be evenly divided into two halves.

[0085] In this embodiment, the medicine outlet component 4 is arranged in the mounting base 13 and is located below the blade 3, which is convenient for the cut tablets to fall out. Figure 7 The position relationship diagram between the medicine outlet component 4 and the blade 3 is shown. The medicine outlet of the medicine outlet component 4 is an arc corresponding to the shape of the rotor 21, and both the cut upper half tablet and the lower half tablet can smoothly fall into the medicine outlet.

[0086] In an alternative embodiment, referring to Figures 4 - 6 As shown, the vertical distance between the blade 3 and the mounting base 13 is controlled to be the radius of the stored tablets, which can be realized by arranging a spacer 102 with a height of the radius of the stored tablets between the blade 3 and the mounting base 13, and fixing them with a plurality of fasteners 103 (such as pins) passing through the blade 3, the spacer 102 and the mounting base 13.

[0087] In the embodiment of the present invention, when the half - tablet cutting cartridge 100 is working, the rotating die core 2 is driven to rotate by the motor 201. The blade 3 cuts the tablet into two half - tablets, and the cut half - tablets fall out from the medicine outlet, thus realizing the instant cutting of the tablets and the taking of the half - tablets, solving the problem that the sub - packaging machine is difficult to provide half - tablets, helping to improve the function of the sub - packaging machine, increasing the automation degree of the sub - packaging machine, and expanding the applicable scenarios of the sub - packaging machine. At the same time, by cutting the tablets evenly in time when half - tablets are needed, the problem of difficult medicine outlet caused by the irregular shape of the half - tablets is solved, and the problems of medicine powder waste caused by pre - cutting the tablets and the difficulty in long - term storage of the half - tablets are also solved.

[0088] In the embodiment of the present invention, the motor 201 is electrically connected to the control system of the sub - packaging machine and is used to drive the rotating die core to rotate. Refer to Figure 1 As shown, the output shaft 2011 of the motor 201 is arranged vertically upward. When the half - tablet cutting cartridge 100 is installed on the motor base 200, the transmission shaft 22 of the rotating die core 2 is in transmission connection with the output shaft 2011 of the motor 201, so as to be able to drive the rotating die core 2 to rotate.

[0089] In the embodiment of the present invention, refer to Figure 1 and Figure 14 As shown, the motor base 200 is provided with a medicine outlet channel facing the medicine outlet component 4. The dust collection box 202 is inserted into the medicine outlet channel and is used to collect the dust generated when the tablets pass through, which helps to keep the medicine outlet channel clean and reduce cross - contamination.

[0090] In an alternative embodiment, refer to Figures 3 - 8 As shown, the half - tablet cutting cartridge 100 applied to the sub - packaging machine may further include a limit stop 5. The limit stop 5 is located above the blade 3 and is used to separate the tablet to be cut from other tablets in the same column. Specifically, a second annular groove 212 is further provided on the side wall of the rotor 21. The second annular groove 212 is located above the first annular groove 211 and is respectively communicated with a plurality of vertical grooves 213. One end of the limit stop 5 is fixed above the mounting seat 13, and the other end extends into the mounting cylinder 12 and is located in the second annular groove 212. Moreover, the vertical distance between the limit stop 5 and the mounting seat 13 is equal to the diameter of the stored tablets, so that the limit stop 5 can separate the bottom tablet to be cut in a column of tablets from the other tablets above, effectively avoiding the interference of the upper tablets on the cutting and ensuring the smooth progress of the cutting.

[0091] Similarly, the height setting of the limit stop 5 can be realized by arranging a spacer 102 between the blade 3 and the limit stop 5. For repeated parts, they will not be described again. The blade 3, the limit stop 5 and the spacer 102 may be provided with a plurality of through - holes on the side away from the rotor 21 for passing through the fasteners 103.

[0092] In an alternative embodiment, refer to Figures 3 - 8As shown in the figure, the limiting stop piece 5 can be set as a double-layer stop piece. The upper stop piece 51 is used to separate the tablets to be cut from other tablets in the same column. The lower stop piece 52 is sequentially provided with a first elastic piece 521 and a second elastic piece 522 that are inclined downward in the circumferential direction. When the rotary die core 2 rotates, the vertical groove 213 first passes through the first elastic piece 521 and then passes through the second elastic piece 522. The first elastic piece 521 is located above the cutting edge section of the blade 3 to apply a downward pressure to the tablet passing through the blade 3. A receiving piece 104 can be provided below the blade 3. The tablet being cut is located between the first elastic piece 521 and the receiving piece 104, so that the tablet being cut can be clamped and limited up and down, ensuring that the tablet will not move up and down and ensuring uniform cutting. At the end of the cutting edge of the blade 3, a third elastic piece 31 inclined downward is provided. The third elastic piece 31 is located above the medicine outlet component 4, which can keep the two halves of the tablet separated after the tablet is cut and can apply a downward pressure to the lower half of the cut tablet, so as to ensure that the lower half of the tablet can smoothly fall into the medicine outlet of the medicine outlet component 4. After the lower half of the tablet falls, the upper half of the tablet can continue to move on the third elastic piece 31. The second elastic piece 522 is located above the third elastic piece 31, and the circumferential length of the second elastic piece 522 is greater than the circumferential length of the third elastic piece 31, that is, the length of the second elastic piece 522 in the direction of tablet rotation exceeds the third elastic piece 31, so as to be able to apply a downward pressure to the upper half of the cut tablet. The upper half of the tablet moving on the third elastic piece 31 can smoothly fall into the medicine outlet under the action of rotation and the pressure of the second elastic piece 522, thus realizing the sequential dropping of the lower half and the upper half of the cut tablet.

[0093] In a specific embodiment, after a whole tablet is cut into two halves, when the user only needs one half tablet, the motor 201 can be turned off after the lower half tablet falls out, so that the rotary die core 2 stops rotating. If two or more half tablets are needed (for example, in the scenario of taking half tablets in portions), it can also be achieved by controlling the stopping time of the rotary die core 2.

[0094] In an alternative embodiment, referring to Figure 2 and Figure 6 As shown, in order to ensure the aesthetics and safety of the half-tablet cutting medicine box 100, a side shell 6 is provided on the side of the installation cylinder 12, so that the blade 3 and the limiting stop piece 5 are accommodated in the side shell 6.

[0095] In an alternative embodiment, referring to Figures 9 - 12 As shown, the dust collection box 202 includes a collection box body 2021 and a slideway fence 2022. The slideway fence 2022 is obliquely arranged in the collection box body 2021. A dust collection space is formed between the slideway fence 2022 and the bottom of the collection box body 2021. When the tablets bounce and slide, the powder enters the dust collection space, which helps to keep the medicine outlet channel clean and reduce cross contamination.

[0096] In an alternative embodiment, referring to Figures 9 - 12 as shown, a magnetic flank 2023 is provided at the top of the collection box body 2021, and a magnetic fixing member (not shown in the figure) is correspondingly provided on the motor base 200. After the dust collection box 202 is inserted into the medicine outlet channel, the magnetic flank 2023 is attracted to the magnetic fixing member, so that the dust collection box 202 is convenient to fix and disassemble, and the dust collection box 202 can be cleaned regularly in a convenient manner.

[0097] In an alternative embodiment, referring to Figure 6 and Figure 14 as shown, the half tablet medicine box 100 further includes a limiting hoop 7. An annular limiting groove 221 is provided on the outer side wall of the transmission shaft 22 extending out of the mounting seat 13, and the limiting hoop 7 is sleeved in the limiting groove 221 to limit the up and down movement of the rotating die core 2, ensuring that the rotating die core 2 will not jump during operation, and improving the reliability and safety of the medicine box during operation.

[0098] In an alternative embodiment, referring to Figure 14 as shown, a magnet 8 and an RFID tag 9 are installed at the bottom of the mounting seat 13. Among them, the RFID tag 9 is an adhesive label, which can define and manage the functions of the medicine box, such as storing medicine information inside, the storage capacity of the medicine box itself (particle size, quantity, remaining capacity, etc.). The magnet 8 is used to cooperate with the Hall sensor 204 on the motor base 200 to detect whether the medicine box is installed and to start reading the RFID tag 9.

[0099] In an alternative embodiment, referring to Figure 13 and Figure 14 as shown, the medicine outlet component 4 is detachably installed in the mounting seat 13, which is convenient for cleaning the medicine outlet; the medicine outlet component 4 is located below the blade 3, and a convex curved landslide 41 is provided in the medicine outlet at its center, so that the tablets can slide out smoothly.

[0100] In an alternative embodiment, referring to Figure 2 and Figure 15As shown, the half-cut medicine box 100 also includes an upper cover 10 that is covered on the medicine cup 11. A hollow grid frame 101 that is connected to the inside of the medicine cup 11 is provided at the center of the upper cover 10, and a desiccant 300 and a tablet sample 400 can be placed in the hollow grid frame 101. Specifically, the hollow grid frame 101 can be divided into two parts, one part is used to place the desiccant 300, so as to keep the inside of the medicine cup 11 dry and clean, and the medicine is stored reliably and not easy to deteriorate, and the other part is used to place the tablet sample 400, so as to provide a prompt of the shape of the tablet and ensure the accuracy of the tablet storage. Obviously, in order to keep the desiccant 300 with a good moisture absorption effect, the desiccant 300 needs to be replaced regularly, as short as half a year and as long as one year, and the replacement cycle can be adjusted according to actual conditions. A sealing cover (not shown in the figure) is provided above the hollow grid frame 101, which can prevent external foreign matter from entering the medicine cup 11 and ensure the cleanliness of the medicine in the medicine cup 11.

[0101] In an alternative embodiment, referring to Figure 2 As shown, the main housing 1 further includes a support column 14. The upper and lower ends of the support column 14 are respectively connected to the medicine cup 11 and the mounting seat 13 to support the medicine cup 11 and improve the force stability and placement stability of the half-cut medicine box 100.

[0102] In an alternative embodiment, referring to Figure 3 and Figure 14 As shown, the transmission shaft 22 and the output shaft 2011 of the motor 201 can be connected in a transmission manner: an internal gear 222 is provided at the bottom of the transmission shaft 22, and the transmission connection is achieved by meshing the internal gear 222 with the external teeth on the output shaft 2011 of the motor 201.
