Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0024] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0025] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "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. 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 circumstances.

[0026] Such as Figures 1 to 16As shown in the figure, a sorting device for traditional Chinese medicine decoction pieces raw materials according to the present invention includes: Raw material primary processing production line 1; Dust removal and slicing device 2, the inlet end of the dust removal and slicing device 2 is communicated with the outlet end of the raw material primary processing production line 1, and the raw materials processed by the raw material primary processing production line 1 are transported into the dust removal and slicing device 2; Raw material sorting device (not shown in the figure), the inlet end of the raw material sorting device is communicated with the outlet end of the dust removal and slicing device 2; Among them, the dust removal and slicing device 2 includes a buckling cover 21 and a negative pressure passage 22; in the working position, the buckling cover 21 buckles on the raw materials, and the buckling cover 21 is communicated with the negative pressure passage 22 to form a negative pressure chamber in the inner cavity of the buckling cover 21; the raw materials rotate in the inner cavity of the buckling cover 21 to impact the inner wall of the buckling cover 21.

[0027] By applying a sorting device for traditional Chinese medicine decoction pieces raw materials provided by the present invention, before sorting the qualified traditional Chinese medicine decoction pieces raw materials, a step of cleaning and slicing the raw materials through a dust removal and slicing device is added, which ensures the accuracy of subsequent qualification detection.

[0028] More specifically: In the prior art, the raw materials of traditional Chinese medicine decoction pieces adhering to soil or other sundries increase in weight due to the sundries, resulting in misjudgment as qualified during weighing detection. The present invention realizes dust removal through the provided dust removal and slicing device. Due to the existence of the negative pressure chamber, on the one hand, under the action of the pressure difference between the external atmospheric pressure and the negative pressure in the chamber, the lighter sundries such as soil and dust adhering to the surface of the raw materials will be sucked into the negative pressure passage due to the unbalanced force, so as to separate from the surface of the raw materials; on the other hand, the raw materials rotate in the inner cavity of the buckling cover, and during the rotation process, the raw materials will impact the inner wall of the buckling cover, and this impact will generate an impact force on the sundries adhering to the surface of the raw materials, so that the originally firmly attached sundries can also be shaken off. The sundries on the surface of the raw materials are effectively removed, ensuring the cleanliness of the surface of the raw materials, avoiding detection errors caused by sundries, and thus ensuring the accuracy rate of qualification detection; For traditional Chinese medicine raw materials (such as polygonatum slices, dried tangerine peels, etc.) that are curled after dehydration and stacked in multiple layers, in the prior art, they are misjudged as qualified because the weight reaches the standard when multiple layers are stacked. In the present invention, when the raw materials rotate in the negative pressure chamber formed by the buckling cover, relative movement will occur between the multiple stacked raw materials due to the rotation. At the same time, when hitting the inner wall of the buckling cover, the directions and magnitudes of the impact forces and frictional forces received by each raw material slice are different. The action of these forces will break the mutual adsorption and stacking state between the multiple raw materials, causing the stacked raw materials to separate from each other and realizing slicing. In addition, the suction force generated by the negative pressure will also apply an outward pulling force to the stacked raw materials to assist them in dispersing. In this way, it is ensured that the raw materials entering the raw material sorting device are in a single-piece state, avoiding misjudgment of weight caused by multiple-layer stacking, and further ensuring the accuracy of subsequent qualification testing.
