Description

Technical Field

[0001] This utility model belongs to the field of color sorting machine technology, and in particular relates to a color sorting mechanism for Chinese herbal medicine slices. Background Technology

[0002] Color sorting is a crucial and widespread quality control process in the modern production of Chinese medicinal herbs. It is primarily achieved through automated color sorters (suitable for regular granules / slices) and / or manual sorting (suitable for herbs with complex shapes). Its core purpose is to remove foreign matter, impurities, spoiled products, and severely substandard items, ensuring the purity, uniformity, and safety of the herbs, and ultimately improving the product's quality grade. Although the implementation methods vary depending on the shape of the herbs, its role in ensuring the quality of Chinese medicinal herbs is indispensable.

[0003] Currently, during the feeding process of color sorters, some Chinese herbal medicine slices overlap and stack due to the feeding speed. When passing through the image recognition area, the machine cannot accurately identify the quality of the obscured slices (such as mold, insect infestation, impurities, etc.), resulting in the missed detection of defective products. This is one of the main technical pain points of color sorters in the application of Chinese medicine.

[0004] To address the aforementioned issues, this application proposes a color sorting mechanism for traditional Chinese medicine decoction pieces. Utility Model Content

[0005] The purpose of this invention is to provide a color sorting mechanism for Chinese herbal medicine slices, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a color sorting mechanism for Chinese herbal medicine slices, including a color sorter;

[0008] The main structure of the color sorter is a frame, with a color sorting section near the lower end, a dual-zone hopper at the lower end, and a material frame at the upper end;

[0009] The color sorter has a downward-extending slide on the left side and a fixed frame for transferring Chinese herbal medicine pieces on the right side of the slide. A rotary blade is rotatably installed inside the fixed frame to transfer the Chinese herbal medicine pieces. A convex frame is provided on the left side of the fixed frame near the lower end. A paddle is fixedly installed inside the outer opening of the convex frame. The paddle has two working states: open and closed.

[0010] The right side of the fixing frame is provided with negative pressure cylinders with equal and parallel axes, and the right side of the fixing frame is provided with a double-segment groove corresponding to the negative pressure cylinders.

[0011] Preferably, a rotating shaft is rotatably mounted inside the fixed frame, and the swivel blades are evenly distributed circumferentially on the outer side of the rotating shaft.

[0012] Preferably, the negative pressure cylinder has an air vent on its left side that connects to the double-segment groove.

[0013] Preferably, a partition net is fixedly installed inside the dual-segment groove, with the upper segment being a vertical structure and the lower segment being an arc-shaped structure.

[0014] Preferably, the lower end of the material frame is provided with a feeding plate, and a guide plate extends obliquely downward from its end into the interior of the fixed frame.

[0015] Preferably, the end of the blade rotates in contact with the inner wall of the lower end of the fixing frame.

[0016] Preferably, the opening of the convex frame is adjacent to the inner wall of the carriage.

[0017] This utility model has the following beneficial effects:

[0018] This invention uses a fixed frame to transfer the downward-falling Chinese herbal medicine slices, and uses an intermittent conveying method with rotating blades to disperse the Chinese herbal medicine slices into the slide under the action of the paddle, thereby avoiding misjudgment caused by the stacking of Chinese herbal medicine slices passing through the image recognition area. At the same time, the transfer of the fixed frame also creates a buffering effect to prevent the dried Chinese herbal medicine slices from being bumped and damaged due to the height difference.

[0019] This invention improves the color sorting quality of Chinese herbal medicine slices by rotating the blades so that the slices rotate through the mesh at different positions, exposing the residue and allowing it to be sucked in by the negative pressure cylinder.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0037] Please see Figure 1-4 As shown, this utility model is a color sorting mechanism for Chinese herbal medicine slices, including a color sorter 1. The main body of the color sorter 1 is a frame 11, a color sorting section 12 is provided near the lower end, a double-zone hopper 13 is provided at the lower end, and a material frame 14 is provided at the upper end.

[0038] The color sorter 1 has a slide 15 extending diagonally to the lower right on the left side, and a fixed frame 16 is provided on the right side of the slide 15 to transfer Chinese herbal medicine pieces. The lower end of the fixed frame 16 is a semi-circular structure, and the upper end is a square open frame, which is used to transfer Chinese herbal medicine pieces to form a buffer and prevent the Chinese herbal medicine pieces from falling directly to the slide 15 and being bumped and damaged.

[0039] Rotary blades 1621 are rotatably installed inside the fixed frame 16. An open groove is formed between adjacent rotary blades 1621. The Chinese herbal medicine pieces fall directly into the groove and are transferred as the rotary blades 1621 rotate. A protruding frame 163 is fixedly installed on the left side of the fixed frame 16 near the lower end. It has a double-opening structure. A paddle 1631 is fixedly installed inside the outer opening of the protruding frame 163. The paddle 1631 has two working states: open and closed. When it is open, the lower end of the paddle 1631 rotates outward and unfolds, thereby restricting the discharge of the Chinese herbal medicine pieces and dispersing them into the slide 15.

[0040] The right side of the fixed frame 16 is provided with a negative pressure cylinder 161 with the same height and parallel axis, which is connected to an external negative pressure machine for sucking out the Chinese medicine decoction pieces and residues inside the fixed frame 16. The right side of the fixed frame 16 is provided with a double-segment groove 1641 corresponding to the negative pressure cylinder 161, located at the junction of the square frame and the semi-circular frame.

[0041] Furthermore, a rotating shaft 162 is rotatably installed inside the fixing frame 16, and adjacent fixing frames 16 are penetrated by the rotating shaft. Rotary blades 1621 are evenly distributed around the outside of the rotating shaft 162. The ends of the rotary blades 1621 are attached to the inner wall of the lower end of the fixing frame 16 and rotate to prevent Chinese medicine slices from entering the gap and causing blockage.

[0042] Furthermore, an air vent 1611 is provided on the left side of the negative pressure cylinder 161, which is connected to the double-segment groove 1641. A partition net 164 is fixedly installed inside the double-segment groove 1641. Both the double-segment groove 1641 and the partition net 164 are a combination structure of a vertical upper section and an arc-shaped lower section.

[0043] Furthermore, a feeding plate 141 is provided at the lower end of the material frame 14, and a guide plate 142 extends obliquely downward from its end into the interior of the fixed frame 16. When the blade 1621 rotates to this area, the opening of the adjacent blade 1621 is directly opposite the guide plate 142, which is used to reduce the height difference and control the feeding amount of Chinese medicine decoction pieces, prevent them from stacking into the slide 15, and more thoroughly remove the debris.

[0044] Furthermore, the opening of the convex frame 163 is adjacent to the inner wall of the carriage 15, further reducing the height difference.

[0045] Understandably, this utility model can form a transfer when feeding Chinese herbal medicine slices to reduce the impact damage caused by the height difference. At the same time, it automatically sucks up the debris during the transfer to form a pre-screening process. Finally, it forms a dispersion process when the Chinese herbal medicine slices are sent out to avoid stacking into the color sorting section 12.

[0046] A specific application of the operation flow of this embodiment is as follows: During use, the Chinese herbal medicine slices in the feed frame 14 are guided by the feed plate 141 and the guide plate 142 into the space between adjacent rotating blades 1621 in the fixed frame 16. The rotating blades 1621 rotate, causing the slices to move. When the rotating blades 1621 receiving the Chinese herbal medicine slices rotate to the upper end of the double-stage groove 1641, the slices gather to the left, exposing the fragments. Upon entering the area of ​​the double-stage groove 1641, they are sucked in by the negative pressure cylinder 161 and continue to rotate into the double-stage groove. Near the lower end of the groove 1641, the rotary blade 1621 tilts to the lower right, and the accumulated Chinese herbal medicine pieces gather to the right, exposing the buried debris again. They are then sucked up again by the negative pressure cylinder 161, thus forming a two-stage suction to remove the debris. When the rotary blade 1621 rotates to the opening inside the convex frame 163 on the left, the Chinese herbal medicine pieces gather inside the convex frame 163 and enter the interior of the carriage 15 under the action of the paddle 1631, thereby forming a dispersion to avoid stacking in the area where the color sorting section 12 is located.
