Description

Technical Field

[0001] This invention belongs to the field of sorting technology for raw materials of traditional Chinese medicine decoction pieces, specifically, it relates to a sorting device and sorting method for raw materials of traditional Chinese medicine decoction pieces. Background Technology

[0002] Prepared medicinal herbs refer to Chinese medicinal materials that, under the guidance of traditional Chinese medicine theory, have undergone processing and can be directly used in clinical practice or pharmaceutical production. The quality of the raw materials directly affects the quality of the prepared medicinal herbs.

[0003] For the testing of the qualification of raw materials for traditional Chinese medicine decoction pieces, one important indicator is the quality of individual raw materials. In existing technologies, quality is tested by weighing with a weighing device to determine the integrity of the raw materials. The technical solution with application number 202411297617.4 discloses a sorting and weighing device for defective medicinal tablets, including a vibrating disc and a sorting conveyor belt. A feeding component is arranged between the vibrating disc and the sorting conveyor belt. Several sorting components are arranged on the sorting conveyor belt. A qualified conveyor belt and a defective conveyor belt are arranged at the end of the sorting conveyor belt away from the vibrating disc. The feeding component includes a feeding disc and several feeding troughs equidistantly arranged on the feeding disc. The sorting component includes a weighing device and a linear actuator to separate damaged and unqualified medicinal tablets. The proposed solution can, to some extent, distinguish between qualified and unqualified raw materials of Chinese herbal medicine. However, for raw materials of Chinese herbal medicine that are covered with soil or other impurities, or raw materials of Chinese herbal medicine that are curled up after dehydration and have multiple pieces overlapping (such as Solomon's seal slices, dried tangerine peel, etc.), they are usually classified as qualified raw materials because their overall weight meets the standard during testing. This results in a low accuracy rate of qualification testing and affects the quality of the Chinese herbal medicine produced subsequently.

[0004] Therefore, there is an urgent need to provide a sorting device and method for raw materials of Chinese herbal medicine that can remove dust and separate the raw materials before distinguishing their qualification, thereby improving the accuracy of qualification detection, in order to solve the above problems.

[0005] In view of the above, this application is hereby submitted. Summary of the Invention

[0062] like Figures 1 to 16 As shown, the present invention provides a sorting device for raw materials of traditional Chinese medicine decoction pieces, comprising:

[0063] Raw material primary processing line 1;

[0064] Dust removal and slicing device 2, the inlet end of the dust removal and slicing device 2 is connected to the outlet end of the raw material primary processing line 1, and the raw materials processed by the raw material primary processing line 1 are transported to the dust removal and slicing device 2.

[0065] A raw material sorting device (not shown in the figure) has its inlet end connected to the outlet end of the dust removal and slicing device 2.

[0066] The dust removal and slicing device 2 includes a cover 21 and a negative pressure passage 22. In the working position, the cover 21 covers the raw material and is connected to the negative pressure passage 22 to form a negative pressure chamber in the inner cavity of the cover 21. The raw material rotates in the inner cavity of the cover 21 to impact the inner wall of the cover 21.

[0067] By applying the Chinese herbal medicine raw material sorting device provided by this invention, an additional step is added before the raw materials are sorted for qualification, through a dust removal and slicing device to clean and slice the raw materials, thus ensuring the accuracy of subsequent qualification testing.

[0068] More specifically:

[0069] In existing technologies, the weight of raw materials for traditional Chinese medicine decoction pieces adhering to dirt or other impurities increases due to these impurities, leading to misjudgments of passability during weighing tests. This invention addresses this issue by employing a dust removal and slicing device. Due to the presence of a negative pressure chamber, on one hand, the pressure difference between the external atmospheric pressure and the negative pressure inside the chamber causes lighter impurities such as dirt and dust adhering to the surface of the raw materials to be drawn into the negative pressure passage due to the imbalance of forces, thus detaching from the surface. On the other hand, as the raw materials rotate within the inner cavity of the cover, they impact the inner wall of the cover, generating an impact force on the impurities adhering to the surface, causing even firmly attached impurities to be shaken off. This effectively removes impurities from the surface of the raw materials, ensuring surface cleanliness and avoiding detection errors caused by impurities, thereby ensuring the accuracy of passability testing.

[0070] For traditional Chinese medicine raw materials (such as Solomon's seal slices and dried tangerine peel) that have curled up after dehydration and are stacked in multiple pieces, existing technologies mistakenly classify them as qualified because the weight of the stacked pieces meets the standard. In this invention, when the raw materials rotate within the negative pressure chamber formed by the cover, the stacked pieces experience relative motion due to the rotation. Simultaneously, when impacting the inner wall of the cover, the impact and friction forces experienced by each piece differ in direction and magnitude. These forces break the mutual adsorption and stacking state between the pieces, causing them to separate and achieve fragmentation. Furthermore, the suction force generated by the negative pressure also applies an outward pulling force to the stacked pieces, further assisting in their dispersion. This ensures that the raw materials entering the sorting device are in a single-piece state, avoiding misjudgment of weight due to multiple stacked pieces, and further ensuring the accuracy of subsequent qualification testing.

[0071] In one specific embodiment of this example, the raw material primary processing line 1 performs primary processing on the raw materials, such as cleaning and drying.

[0072] In one specific embodiment of this example, the raw material sorting device is used to separate qualified and unqualified raw materials (the raw material sorting device is structurally the same as or similar to the prior art mentioned in the background art).

[0073] Please see the appendix Figure 1 Appendix Figure 3 To be continued Figure 5 In one specific embodiment of this example, the dust removal and segmentation device 2 further includes a cuboid outer shell 23; the inlet end of the dust removal and segmentation device 2 is disposed on the top plate of the outer shell 23; the inlet end includes a material collection tray 24 disposed on the outside of the outer shell 23 and a material injection pipe 25 disposed on the inside of the outer shell 23 and communicating with the material collection tray 24;

[0074] The dust removal and slicing device 2 further includes: a conveying mechanism 4, which is arranged along the length direction parallel to the outer shell 23, with one end of the conveying mechanism 4 extending out of the outer shell 23 away from the raw material primary processing line 1; and the material injection pipe 25 is arranged close to the conveying mechanism 4 at one end away from the material collection tray 24.

[0075] In this invention, the pre-processed raw materials are conveyed to the dust removal and slicing device 2 by lifting them to a higher height. When the raw materials fall onto the conveying device through the injection pipe 5, the dust adhering to the raw materials can be thrown off, thus initially ensuring the cleanliness of the raw materials.

[0076] In one specific embodiment of this example, the outer shell 23 of the dust removal and segmentation device 2 includes: a top plate, a bottom plate, a front plate, a rear plate, a left plate, and a right plate; wherein the top plate and the bottom plate are arranged opposite to each other, the front plate and the rear plate are arranged opposite to each other, and the left plate and the right plate are arranged opposite to each other.

[0077] In one specific embodiment of this example, the conveying mechanism 4 extends from the right plate of the outer casing 23 at one end away from the raw material primary processing line 1 (the end closer to the raw material sorting device).

[0078] In one specific embodiment of this example, the injection pipe 25 is provided with an on / off valve (not shown in the figure) that can be controlled to open and close.

[0079] The opening and closing valve realizes the opening and closing of the material injection pipe 25 according to specific control requirements, thereby controlling the on-demand delivery of raw materials that have been pre-processed by the raw material pre-processing production line 1 (for example, realizing the delivery at intervals of period t, so that the raw materials falling on the conveyor belt 41 correspond in position to the set cover 21).

[0080] In one specific embodiment of this example, a vent 26 is provided on the left plate of the outer casing 23, and a filter hood 27 is provided on the vent 26.

[0081] In one specific embodiment of this example, the dust removal and segmentation device 2 further includes: a support leg 28, wherein a plurality of support legs 28 are provided, and the plurality of support legs 28 are arranged in a rectangular array;

[0082] The support leg 28 is located on the side of the bottom plate of the outer casing 23 away from the top plate; the support leg 28 supports the outer casing 23 on the ground.

[0083] In one specific embodiment of this invention, the support leg 28 is a retractable support leg.

[0084] Please see the appendix Figure 1 and attached Figure 2In one specific embodiment of this example, the raw material primary processing line 1 includes a tracked conveyor mechanism 11, which lifts the primary processed raw materials into the collection tray 24 of the dust removal and slicing device 2.

[0085] In one specific embodiment of this example, the collecting tray 24 is a cuboid or cylindrical structure with an open top; openings are provided at corresponding positions on the top plate of the outer shell 23 and the bottom plate of the collecting tray 24, and the openings are connected to the injection pipe 25.

[0086] In another specific embodiment of this example, the collecting tray 24 is a square hollow tube or a circular tube structure; the top plate of the outer shell 23 is provided with a through-hole, which is connected to the injection pipe 25.

[0087] In one specific embodiment of this example, the top plate of the outer shell 23 may be provided with a plurality of openings, and each opening is connected to an injection pipe 25.

[0088] Please see the appendix Figure 6 To be continued Figure 10 In one specific embodiment of this example, the cover 21 is a box-shaped structural component with one end open;

[0089] The dust removal and segmentation device 2 further includes: a circulating rotation mechanism 3, on which a plurality of the buckles 21 are spaced apart; the circulating rotation mechanism 3 is disposed inside the outer shell 23, and is disposed at one end away from the injection pipe 25 (the end away from the left plate and close to the right plate).

[0090] The telescopic mechanism 31 has one end connected to the rotating belt 32 of the circulating rotating mechanism 3 and the other end connected to the cover 21. In the working position, the telescopic mechanism 31 extends and the cover 21 is pressed against the conveyor belt 41 of the conveying mechanism 4. The working position refers to the position where the cover 21 follows the circulating rotating mechanism 3 and is located on the side close to the conveying mechanism 4.

[0091] In one specific embodiment of this example, the circulating rotation mechanism 3 is connected to the top plate of the outer casing 23 on the side facing closer to the bottom plate (located on the inner side of the top plate of the outer casing 23) via a connecting column.

[0092] In one specific embodiment of this example, a rubber skirt (not shown in the figure) is provided around the open end of the cover 21; when the cover 21 is pressed onto the conveyor belt 41 of the conveying mechanism 4 by the telescopic mechanism 31, the rubber skirt contacts the conveyor belt 41.

[0093] Please see the appendix Figure 13 To be continued Figure 15 In one specific embodiment of this invention, the buckle 21 includes:

[0094] An air supply box 5 is provided along the length direction parallel to the cover 21; a plurality of air holes 51 are provided on one outer wall of the air supply box 5, and the plurality of air holes 51 are distributed in a rectangular array.

[0095] A hollow rotating shaft 52 passes through the side wall of the cover 21 and communicates with the air supply box 5; in the working position, the hollow rotating shaft 52 drives the air supply box 5 to rotate around itself as an axis;

[0096] A rubber turntable 53 is sleeved on the outer end of the hollow rotating shaft 52, and the rubber turntable 53 is disposed in a hole on the side wall of the cover 21 for the hollow rotating shaft 52 to pass through.

[0097] In this invention, by setting the rubber turntable 53, when the rubber turntable 53 rotates relative to the cover 21, the eccentric force generated by the hollow rotating shaft 52 due to the influence of the cam will cause the rubber turntable 53 to deform. This deformation can further enhance the shaking degree of the raw materials inside the cover 21, which has a positive effect on dust removal and sheet separation.

[0098] In one specific embodiment of this example, a weighing device 54 is also provided on the side of the air supply box 5 where the air hole 51 is provided; each weighing device 54 has a vent hole 55 at its center, the vent hole 55 being the same size as the air hole 51, and the weighing device 54 is installed on the outside of the air supply box 5.

[0099] Multiple weighing devices 54 are provided, and the multiple weighing devices 54 are arranged in a rectangular array corresponding to the air holes 51.

[0100] In one specific embodiment of this example, the air supply box 5 is a hollow cuboid box.

[0101] The distance between the diagonal lines of the air supply box 5 is less than the width of the cover 21 (and its length in the direction perpendicular to the front and rear plates) to ensure that the air supply box 5 can rotate normally in the cover 21.

[0102] Please see the appendix Figure 13 To be continued Figure 15 In one specific embodiment of this example, the air supply box 5 is provided with a first guide rod 56 and a second guide rod 57, and the two guide rods (the first guide rod 56 and the second guide rod 57) are arranged parallel to each other along the length direction of the air supply box 5.

[0103] The air supply box 5 is also provided with an extension rod 58 and a push-pull slide plate 59. The extension rod 58 extends from the side wall of the cover 21. The extension end of the extension rod 58 is positioned opposite to the hollow rotating shaft 52 provided on the air supply box 5. The push-pull slide plate 59 is equal in size to the cavity cross-section of the air supply box 5 along a projection parallel to the length of the air supply box 5. The push-pull slide plate 59 is provided at the other end of the extension rod 58. The push-pull slide plate 59 is provided with a first through hole and a second through hole corresponding to the first guide rod 56 and the second guide rod 57, respectively.

[0104] The outer shell 23 of the dust removal and slicing device 2 also includes a front plate and a rear plate that are perpendicular to its own thickness direction and arranged opposite to each other;

[0105] The dust removal and slicing device 2 further includes: a guide plate 6, the guide plate 6 including a triangular plate 61; the distance between the end of the triangular plate 61 closest to the raw material primary processing line 1 and the front plate is greater than the distance between the end of the triangular plate 61 furthest from the raw material primary processing line 1 and the front plate; the protruding end of the extension rod 58 abuts against the hypotenuse of the triangular plate 61.

[0106] In this invention, by setting the guide plate 6, as the cover moves, it acts on the extension rod 58, and then moves through the set push-pull slide plate 59, changing the volume of the part connected to the air passage rod 82 in the air supply box 5, thereby gradually changing the actual adsorption area of ​​the air supply box for raw materials.

[0107] In one specific embodiment of this example, one end of the first guide rod 56 (and the second guide rod 57) is connected to the inner wall of the air supply box 5, and the other end is connected to the side of the rubber turntable 53 facing the air supply box 5.

[0108] In one specific embodiment of this example, the guide plate 6 further includes a rectangular plate 62, which is integrally formed with the triangular plate 61, and the rectangular plate 62 is disposed at one end of the triangular plate 61 near the right plate;

[0109] The width of the rectangular plate 62 (the length of which is perpendicular to the direction between the front and rear plates) is the same as the width of the triangular plate 61.

[0110] In one specific embodiment of this invention, along the length direction of the dust removal and segmentation device 2 (which is also perpendicular to the left and right plates), the length of the triangular plate 61 is greater than the length of the rectangular plate 62.

[0111] In one specific embodiment of this example, a first guide groove (not shown in the figure) is provided on the end face of the triangular plate 61 and rectangular plate 62 of the guide plate 6 at the end where the extension rod 58 abuts, and the end of the extension rod 58 extends into the first guide groove.

[0112] In one specific embodiment of this example, a return spring (not shown in the figure) is sleeved on the outer side of the protruding end of the protruding rod 58.

[0113] When the extension rod 58 abuts against the triangular plate 61 and drives the push-pull slide plate 59 to move closer to the hollow rotating shaft 52, the return spring is (gradually) compressed until it is compressed to the maximum compression state.

[0114] When the end of the extension rod 58 moves to the junction of the triangular plate 61 and the rectangular plate 62 and then moves along the rectangular plate 62, the return spring is in the maximum compression state.

[0115] In this invention, by setting the reset spring, it plays a role in resetting when the extended rod disengages from the guide plate, which facilitates the stable realization of the next process cycle.

The distance between the transmission gear 521 and the air supply box 5 is less than the distance between the cam 522 and the air supply box 5.

[0117] The protruding end (longer end) of the cam 522 is positioned opposite to the side of the air supply box 5 where the air hole 51 is located (that is, the converging end of the cam 522 and the side of the air supply box 5 where the air hole 51 is located face the same direction, for example, both facing the front plate, or both facing the rear plate, or both facing the top plate, or both facing the bottom plate, or both facing the position between two adjacent plates).

[0118] The dust removal and segmentation device 2 further includes: a guide plate 7, which guides the movement of the hollow rotating shaft 52;

[0119] The guide plate 7 includes a first plate 71, a second plate 72, and a receiving groove 73 connected thereto, wherein the angle between the extension lines of the first plate 71 and the second plate 72 is an acute angle; the second plate 72 is provided with a rack structure matching the transmission gear 521 at one end near the first plate 71 and at one end near the bottom plate of the outer casing 23; the receiving groove 73 is provided on one side of the second plate 72 near the front plate of the outer casing 23 and at one end of the second plate 72 away from the first plate 71; there is a distance between the end of the receiving groove 73 near the first plate 71 and the end of the rack structure on the second plate 72 away from the first plate 71; a long strip-shaped permanent magnet 74 is provided in the receiving groove 73, the length of the permanent magnet 74 being less than or equal to the length of the receiving groove 73; when the transmission gear 521 on the hollow rotating shaft 52 of the cover 21 disengages from the rack structure, the protruding end of the cam 522 on the hollow rotating shaft 52 of the cover 21 is attracted by the permanent magnet 74.

[0120] In one specific embodiment of this example, the distance between the end of the rack structure on the second plate 72 near the right plate (the end away from the first plate 71) and the right plate is equal to the distance between the end of the rectangular plate 62 away from the triangular plate 61 (the end near the right plate) and the right plate.

[0121] That is, when the end of the extension rod 58 disengages from the guide plate 6, the return spring drives the extension rod 58 to return to its original position, and the transmission gear 521 on the hollow rotating shaft 52 disengages from the rack structure on the second plate 72 of the guide plate 7.

[0122] Please see the appendix Figure 10 To be continued Figure 12 In one specific embodiment of this example, the protrusion height of the peripheral wall of the receiving groove 73 at the end away from the first plate 71 is greater than the protrusion height of the peripheral wall of the receiving groove 73 at the end close to the first plate 71.

[0123] Projected along a direction parallel to the length of the dust removal and slicing device 2, the peripheral wall of the end of the receiving groove 73 away from the first plate 71 partially overlaps with the cam 522; when the protruding end of the cam 522 moves to contact the peripheral wall of the receiving groove 73, the cam 522 is moved, causing the hollow rotating shaft 52 to rotate, and the air supply box 5 to rotate, so that the raw materials originally on its upper side fall onto the conveyor belt 41 of the conveying mechanism 4.

[0125] The air inlet 211 is located on the peripheral wall of the cover 21 at one end away from the circulating rotation mechanism 3.

[0126] When the cover is fastened onto the conveyor belt, the vacuum pump is activated, and the air supply box rotates around the hollow turntable, causing the position of the air vent 51 to change periodically. Outside air enters the cover through the air inlet 211, and the air inside the cover enters the air supply box through the air vent 51, and then exits the cover through the hollow rotating shaft 52. The raw materials inside the cover move with the gas flow amidst the gas disturbance, impacting the inner wall of the cover.

[0127] Please see the appendix Figure 10 To be continued Figure 16 In one specific embodiment of this invention, the dust removal and segmentation device 2 further includes: an air passage rod 82 arranged along the length direction of the dust removal and segmentation device 2, the air passage rod 82 being arranged on the side close to the hollow rotating shaft 52; an exhaust fan 83 being arranged on the side of the air passage rod 82 away from the hollow rotating shaft 52; the air passage rod 82 includes the negative pressure passage 22, the negative pressure passage 22 being connected to the air pipe of the exhaust fan 83;

[0128] When the transmission gear 521 on the hollow rotating shaft 52 meshes with the rack structure of the second plate 72, the negative pressure passage 22 is connected to the hollow rotating shaft 52.

[0129] In one specific embodiment of this example, a one-way valve is also provided on the pipeline on which the exhaust fan 83 is installed. The one-way valve only allows gas to flow from the negative pressure passage 22 of the air passage rod 82 to the exhaust fan 83, and does not allow reverse flow.

[0130] In one specific embodiment of this invention, the dust removal and segmentation device 2 further includes: an annular guide portion 8;

[0131] The guide section includes a solid rod 81 and an air passage rod 82, which are arranged to form an ellipse.
