Description

Technical Field

[0001] This invention belongs to the technical field of traditional Chinese medicine production equipment, and relates to an automatic medicine crushing machine. Background Technology

[0002] In the production of traditional Chinese medicine, dried medicinal materials need to be crushed into medicinal slices, then decocted and packaged. The common tools for crushing Chinese medicine are the mortar and pestle. After the medicinal materials are put into the mortar, they are crushed by pounding with the pestle. However, during the crushing process, some medicinal materials will be squeezed onto the inner wall of the mortar, which cannot be reached by the pestle, resulting in some medicinal materials being crushed less thoroughly.

[0003] For example, a Chinese patent discloses an automatic mortar and pestle [application number: 201810310204.3], which includes a mortar and pestle assembly, a mortar and pestle assembly, a drive mechanism, and a controller. The mortar and pestle assembly is installed on the mortar and the mortar and pestle assembly extends into the mortar through the mortar and pestle assembly. The controller controls the drive mechanism to work, converting the rotational motion of the drive mechanism into the up-and-down reciprocating motion of the mortar and pestle assembly. The mortar and pestle assembly generates the impact force of the reciprocating motion, which crushes the Chinese medicinal materials sealed in the mortar and mortar and pestle assembly. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing an automatic medicine crusher.

[0005] To achieve the above objectives, the present invention adopts the following technical solutions:

[0006] An automatic medicine mortar includes an outer casing, within which a mortar is provided. The top of the mortar is provided with a bowl-shaped mortar groove. A mortar mechanism is provided directly above the mortar. The mortar mechanism includes a mortar hammer whose bottom end face is adapted to the mortar groove. The mortar groove is provided with a self-gathering mechanism that gathers the medicine when the mortar hammer moves away from the mortar. The mortar mechanism also includes a packaging mechanism disposed between the mortar mechanism and the mortar.

[0007] In the aforementioned automatic mortar and pestle machine, the self-spontaneous mortar and pestle gathering mechanism includes several rotating bodies arranged circumferentially and capable of rotating away from the center of the mortar and pestle groove when subjected to the force of the mortar and pestle hammer, and a driving component that drives the rotating bodies to rotate closer to the center of the mortar and pestle groove when the mortar and pestle hammer moves away from the mortar and pestle table.

[0008] In the above-mentioned automatic mortar and pestle machine, the rotation center of the rotating body is located in the lower middle side of the mortar and when the rotating body rotates to the side away from the center of the mortar and comes into contact with the mortar, the upper end face of the rotating body is flush with the inner surface of the mortar. The end of the rotating body away from the rotation center is flush with the upper end face of the mortar and pestle table. The width of the rotating body gradually decreases from top to bottom.

[0009] In the aforementioned automatic mortar and pestle machine, the driving component includes a spring, one end of which is fixed to the mortar and pestle table, and the other end is fixed to the lower surface of the rotating body.

[0010] In the aforementioned automatic mortar and pestle machine, the packaging mechanism includes a packaging film detachably connected to the outer shell, a plurality of upper elastic connectors are provided at the edge of the packaging film, a lower elastic connector is provided at the center of the lower surface of the packaging film, a plurality of upper hooks corresponding to the upper elastic connectors are provided on the outer shell, a lower hook assembly capable of pulling the packaging film into the mortar and pestle groove is provided inside the mortar and pestle groove, and an exhaust and ventilation assembly connected to the mortar and pestle groove is also provided inside the mortar and pestle groove.

[0011] In the aforementioned automatic mortar and pestle machine, the lower hook assembly includes a vertically arranged lifting trough body whose top is connected to the center of the bottom of the mortar and pestle trough. The lifting trough body is provided with a lifting screw and a lifting assembly that can drive the lifting screw to move up and down in the vertical direction. The top of the lifting screw is fixedly connected to a lower hook.

[0012] In the aforementioned automatic mortar and pestle machine, the lifting assembly includes a lifting sleeve with an internal threaded groove, a lifting screw threaded to the internal threaded groove, a first gear fixedly connected to the lifting sleeve, and a second gear driven by a first motor, wherein the second gear meshes with the first gear.

[0013] In the aforementioned automatic medicine mortar, the exhaust assembly includes an exhaust channel disposed within the mortar, the inner end of which is connected to the upper part of the lifting trough.

[0014] In the aforementioned automatic medicine mortar and pestle machine, the rotating body is also equipped with a vibration component.

[0015] In the aforementioned automatic mortar and pestle machine, the vibration component includes a cam mounting groove disposed on a rotating body. A cam with a concave portion is rotatably fitted inside the cam mounting groove and driven by a second motor. When the concave portion rotates to align with the opening of the cam mounting groove, the concave portion and the inner surface of the mortar and pestle groove are flush.

[0016] Compared with existing technologies, the advantages of this invention are:

[0017] 1. After the medicinal materials are placed into the mortar, the mortar hammer in the mortar mechanism moves up and down vertically to crush the medicinal materials in the mortar. During the process of the mortar hammer rising, the self-gathering mechanism can automatically gather the medicinal materials that are squeezed to the upper side of the inner wall of the mortar so that they can fall to the bottom of the mortar to prevent some medicinal materials from being crushed by the mortar hammer. The packaging mechanism can cover the mortar table. After the mortar is crushed, the crushed medicinal materials can be collected through the packaging mechanism.

[0018] 2. During the pounding process, when the pounding hammer moves downward to pound the medicine, it can apply a force to the rotating body, making the rotating body and the pounding table a single unit. After completing one pounding cycle, as the pounding hammer moves upward, the rotating body can rotate and retract towards the center of the pounding groove under the action of the driving component. This allows the medicinal materials that have been squeezed to the upper side of the inner wall of the pounding groove to fall to the bottom of the pounding groove, preventing some medicinal materials from being missed by the pounding hammer.

[0019] 3. Before adding the medicinal materials, first hang several upper elastic connectors on the packaging film onto the upper hooks on the outer shell. Then connect the lower elastic connector at the center of the lower surface of the packaging film to the lower hook assembly. The air extraction component can extract the air between the packaging film and the inner surface of the mortar, allowing the packaging film to adhere to the inner surface of the mortar. After completing the above steps, the mortar can be used to mortar the medicine. After the mortar completes one mortar, the air extraction component stops working during the upward movement. Under the action of the spring, the rotating body can rotate and retract. At this time, the upper elastic connector connecting the packaging film and the upper hook is stretched. When the mortar rises to the highest point, the air extraction component works to continuously extract the air, so that when the mortar descends to the bottom, the packaging film can adhere to the inner surface of the mortar again.

[0020] 4. During the installation of the packaging film, the lifting assembly can drive the lifting screw to move vertically upward, causing the lower hook to move upward. At this time, the lower elastic connector at the bottom of the packaging film can be connected to the lower hook, and then the upper elastic connector at the edge of the packaging film can be connected to the upper hook. After completing the above operations, the lifting assembly can drive the lifting screw to descend until the lower hook is hidden in the lifting groove. After the medicine is crushed, first remove the upper elastic connector from the upper hook, and then separate the lower elastic connector from the lower hook to remove the packaging film containing the medicine.

[0021] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0028] like Figures 1-4 As shown, an automatic mortar and pestle machine includes an outer shell 1, a mortar and pestle table 2 inside the outer shell 1, a bowl-shaped mortar and pestle groove 3 on the top of the mortar and pestle table 2, a mortar and pestle mechanism 4 directly above the mortar and pestle table 2, a mortar and pestle mechanism 4 including a mortar and pestle hammer 5 whose bottom end face is adapted to the mortar and pestle groove 3, a self-gathering mechanism 6 in the mortar and pestle groove 3 for gathering medicine when the mortar and pestle hammer 5 moves away from the mortar and pestle table 2, and a packaging mechanism 7 disposed between the mortar and pestle mechanism 4 and the mortar and pestle table 2.

[0029] In this invention, after the medicinal materials are placed into the mortar, the mortar hammer 5 in the mortar mechanism moves up and down in the vertical direction to crush the medicinal materials in the mortar. During the process of the mortar hammer 5 rising, the self-gathering mechanism 6 can automatically gather the medicinal materials that are squeezed to the upper side of the inner wall of the mortar so that they can fall to the bottom of the mortar to prevent some medicinal materials from being crushed by the mortar hammer. The packaging mechanism 7 can cover the mortar table. After the mortar is crushed, the crushed medicinal materials can be collected through the packaging mechanism.

[0030] Specifically, the self-priming herb-gathering mechanism 6 includes several circumferentially arranged rotating bodies 8 that can rotate away from the center of the mortar 3 when subjected to the force of the mortar hammer 5, and a driving component 9 that drives the rotating bodies 8 to rotate closer to the center of the mortar 3 when the mortar hammer 5 moves away from the mortar platform 2. During the mortaring process, when the mortar hammer 5 moves downward to mortar the herbs, it can apply a force to the rotating bodies, causing the rotating bodies and the mortar platform to become one. After completing one mortaring cycle, as the mortar hammer moves upward, the rotating bodies can rotate and gather closer to the center of the mortar 3 under the action of the driving component 9. This allows the herbs that have been squeezed to the upper side of the inner wall of the mortar to fall to the bottom of the mortar, preventing some herbs from being caught by the mortar hammer.

[0031] Specifically, the rotation center of the rotating body 8 is located on the lower middle side of the mortar 3, and when the rotating body 8 rotates to the side away from the center of the mortar 3 until it comes into contact with the mortar 3, the upper end face of the rotating body 8 is flush with the inner surface of the mortar 3. The end of the rotating body 8 away from the rotation center is flush with the upper end face of the mortar table 2, and the width of the rotating body 8 gradually decreases from top to bottom.

[0032] Specifically, the driving component 9 includes a crank spring 10, one end of which is fixed to the mortar 2, and the other end is fixed to the lower surface of the rotating body 8. When the rotating body is not subjected to the force of the mortar hammer, the crank spring can drive the rotating body to rotate and retract towards the center of the mortar trough 3.

[0033] Specifically, combining Figures 1-3 As shown, the packaging mechanism 7 includes a packaging film 11 detachably connected to the outer shell 1. Several upper elastic connectors 12 are provided at the edge of the packaging film 11, and a lower elastic connector 13 is provided at the center of the lower surface of the packaging film 11. Several upper hooks 14 corresponding to the upper elastic connectors 12 are provided on the outer shell 1. The mortar 2 is provided with a lower hook assembly 15 that can pull the packaging film 11 into the mortar 3. The mortar 2 is also provided with a suction and exhaust assembly connected to the mortar 3. Before adding the medicinal materials, first hang several upper elastic connectors 12 on the packaging film 11 onto the upper hooks 14 on the outer shell. Then connect the lower elastic connector 13 at the center of the lower surface of the packaging film 11 with the lower hook assembly 15. The air extraction assembly can extract the air between the packaging film 11 and the inner surface of the mortar, so that the packaging film can adhere to the inner surface of the mortar. After completing the above steps, the mortar can be used to mortar the medicine. After the mortar completes one mortar, the air extraction assembly stops working during the upward movement. Under the action of the spring, the rotating body can rotate and retract. At this time, the upper elastic connector 12 connecting the packaging film and the upper hook is stretched. When the mortar rises to the highest point, the air extraction assembly works to continuously extract the air, so that when the mortar falls to the bottom, the packaging film can adhere to the inner surface of the mortar again.

[0034] The packaging film also prevents the mortar from coming into contact with the herbs during mortaring. This not only facilitates packaging but also ensures the purity of the herbs, preventing the mixing of medicinal properties between different batches of herbs using the same mortar.

[0035] Specifically, the lower hook assembly 15 includes a vertically arranged lifting groove 16 whose top is connected to the center of the bottom of the mortar 3. The lifting groove 16 is provided with a lifting screw 17 and a lifting assembly that can drive the lifting screw 17 to move up and down in the vertical direction. The top of the lifting screw 17 is fixedly connected to a lower hook 18. The lifting assembly includes a lifting sleeve 19 with an internal thread groove. The lifting screw 17 is screwed to the internal thread groove. A first gear 20 is fixedly connected to the lifting sleeve 19. It also includes a second gear 22 driven by a first motor 21. The second gear 22 meshes with the first gear 20. During the installation of the packaging film, the lifting screw 17 can be driven to move vertically upward by the lifting assembly, so that the lower hook moves upward. At this time, the lower elastic connector 13 at the bottom of the packaging film can be connected to the lower hook, and then the upper elastic connector 12 at the edge of the packaging film can be connected to the upper hook. After the above operations are completed, the lifting screw is driven to descend by the lifting assembly until the lower hook is hidden in the lifting groove 16. After the medicine is crushed, the upper elastic connector 12 is removed from the upper hook, and then the lower elastic connector and the lower hook are separated to remove the packaging film containing the medicine.

[0036] Motor 21 can drive gear 22 to rotate, gear 22 can drive gear 20 to rotate, gear 20 can drive lifting sleeve 19 to rotate, and lifting sleeve can drive lifting screw to rise and fall in the vertical direction.

[0037] Specifically, the exhaust assembly includes an exhaust channel 23 disposed within the mortar 2, the inner end of which is connected to the upper part of the lifting trough 16. An exhaust fan is connected to the exhaust channel 23, which can extract air between the packaging film 11 and the inner surface of the mortar through the exhaust channel 23 and the lifting trough 16.

[0038] Preferably, combined with Figures 1-5 As shown, the rotating body 8 is also equipped with a vibration component. When the rotating body is retracted, the vibration component can cause the packaging film attached to the rotating body to vibrate, thereby preventing the medicinal materials from adhering to the packaging film.

[0039] Specifically, the vibration assembly includes a cam mounting groove on the rotating body 8. A cam 25 with a recess 24, driven by a second motor, rotatably engages within the cam mounting groove. When the recess 24 rotates to align with the opening of the cam mounting groove, the recess 24 and the inner surface of the mortar 3 become flush. The second motor drives the cam 25 to rotate. When the cam rotates, its convex portion applies power to the packaging film through the opening of the cam mounting groove, causing the packaging film to vibrate. As the mortar descends, the second motor drives the cam 25 to rotate until the recess 24 aligns with the opening of the cam mounting groove.

[0040] Preferably, the bottom periphery of the mortar is further provided with an extension, which can contact the upper surface of the rotating body when the mortar descends, thereby scraping off the medicinal materials adhering to the packaging film.
