Description

Technical Field

[0001] The present invention relates to the technical field of traditional Chinese medicine decoction pieces detection, and specifically to an accurate detection device for the quality of traditional Chinese medicine decoction pieces. Background Art

[0002] Traditional Chinese medicine decoction pieces refer to the processed traditional Chinese medicines under the guidance of traditional Chinese medicine theory. Usually, traditional Chinese medicines will be processed by methods such as cleaning, cutting, and roasting to form decoction pieces after processing, and traditional Chinese medicine decoction pieces are usually cut into relatively uniform shapes and specifications such as slices, segments, and blocks, which are convenient for dispensing and use;

[0003] Some raw materials of traditional Chinese medicine decoction pieces may stick together, and after production processes such as drying, dehydration, and roasting, most of the traditional Chinese medicine decoction pieces on the market do not stick together, such as licorice slices and American ginseng slices. Before such formed decoction pieces are bagged, visual inspection equipment can be used to compare and detect the color and other conditions of the decoction pieces, so as to detect the ex-factory quality of the decoction pieces. Usually, a conveyor belt is used to convey the decoction pieces to the detection area. However, since the decoction pieces often pile up together, it is difficult for the detection device to detect the blocked decoction pieces, resulting in insufficient detection of the decoction pieces, which is rather inconvenient. Moreover, in the existing visual inspection technology, when there are many objects to be detected and the distance is relatively close, the pixel ratio of the objects in the image will increase significantly, which easily leads to an increased computational burden on the detection algorithm and a slower detection speed. In addition, when the distance between the objects to be detected is relatively close, the boundaries between the objects may become blurred, resulting in the detection algorithm being difficult to distinguish different objects, especially when the shapes or colors of the objects to be detected are similar, such situations are more likely to occur, which is rather inconvenient. Summary of the Invention

[0021] 2.

Specific implementation mode

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-7 , in the embodiment of the present invention, a precise detection device for the quality of traditional Chinese medicine decoction pieces includes:

[0034] A U-shaped plate 100, a detection mechanism 200 for detecting traditional Chinese medicine decoction pieces, and a conveying mechanism 300 for separating and transporting traditional Chinese medicine decoction pieces. Vibration boxes 110 are fixedly connected to both opposite sides of the U-shaped plate 100. Vibration motors are arranged inside both of the two vibration boxes 110. The detection mechanism 200 is located above the U-shaped plate 100. The detection mechanism 200 includes two U-shaped frames 210. The two ends of any one U-shaped frame 210 are respectively fixedly connected to the top surfaces of the two arms of the U-shaped plate 100. Guide rollers 211 are rotatably connected between the two arms of any one U-shaped frame 210. Two synchronous toothed belts 230 are arranged between the two guide rollers 211. And two synchronous belt pulleys are arranged inside the two synchronous toothed belts 230. The two synchronous belt pulleys inside any one synchronous toothed belt 230 are respectively fixedly sleeved on the outer side walls of the two guide rollers 211. A moving box 220 is arranged between the two synchronous toothed belts 230. And a plurality of visual detection devices are arranged inside the moving box 220. Moving plates 221 are fixedly connected to both ends of the moving box 220. The two moving plates 221 are respectively fixedly connected to the outer side walls of the two synchronous toothed belts 230. The conveying mechanism 300 is located between the two arms of the U-shaped plate 100.

[0035] Specifically, manually place the traditional Chinese medicine decoction pieces on the conveying mechanism 300, and then start the vibration motor to make the conveying mechanism 300 generate a certain vibration, so that the decoction pieces received on the conveying mechanism 300 are scattered and not easily piled up. Then, use the conveying mechanism 300 to increase the separation distance of the scattered decoction pieces, make the decoction pieces more dispersed and staggered. Then, turn off the vibration motor, and at the same time rotate the two synchronous belts 230 reciprocally, so that the two synchronous belts 230 drive the moving box 220 to move reciprocally, and the visual inspection device inside the moving box 220 automatically inspects the decoction pieces scattered on the conveying mechanism 300, thus facilitating the visual inspection of the decoction pieces. The visual inspection device is a prior art and will not be elaborated here.

[0036] Embodiment 1

[0037] As Figure 2 shown, in this embodiment, each moving plate 221 is rotatably connected with a plurality of moving wheels. One side of a U-shaped frame 210 is fixedly connected with a power box 240, and a power motor is arranged inside the power box 240. The motor shaft of the power motor is fixedly connected with one end of an adjacent guide roller 211.

[0038] In this embodiment, starting the power motor can drive the adjacent guide roller 211 to rotate, and drive the two guide rollers 211 to rotate synchronously through the synchronous belt wheels and the synchronous belt 230, which is convenient for the user to control the power motor to drive the two synchronous belts 230 to rotate reciprocally through the controller, so that the two synchronous belts 230 drive the moving box 220 to move reciprocally. When the moving box 220 moves, it can move more smoothly through the moving wheels on the tops of the two arms of the U-shaped plate 100.

[0039] As Figures 3-7 shown, in this embodiment, the conveying mechanism 300 includes:

[0040] Two rod bodies 310, a driving component, a moving component for receiving traditional Chinese medicine decoction pieces, and two driving rods 350. The two rod bodies 310 are both rotatably connected between the two arms of the U-shaped plate 100, and a plurality of driving components are movably sleeved on the outer side walls of the two rod bodies 310. The plurality of driving components on the two rod bodies 310 correspond to each other. A moving component is arranged between two driving components that are respectively located on the two rod bodies 310 and correspond to each other. The driving component includes two mirror-symmetrical guide wheels 320. Two U-shaped blocks 321 are fixedly connected inside each of the two guide wheels 320, and a ring body 330 is arranged inside each of the two guide wheels 320. Two guide rails 340 are fixedly connected between the two ring bodies 330. The two U-shaped blocks 321 inside the same guide wheel 320 are respectively slidably clamped inside the two guide rails 340. The moving component includes two tape carriers 370, and a rubber belt 371 is fixedly connected between the two tape carriers 370. An annular card slot is formed on the outer side wall of any one of the guide wheels 320. Any one of the tape carriers 370 is rotatably sleeved between the outer side walls of two parallel guide wheels 320 on the two rod bodies 310, and any one of the tape carriers 370 is rotatably clamped inside the adjacent annular card slot. The two driving rods 350 are both rotatably connected between the two arms of the U-shaped plate 100. Annular tooth grooves are formed on the inner side walls of the two ring bodies 330, and two toothed rings 331 are meshed and connected inside each of the two annular tooth grooves. The two toothed rings 331 inside the same annular tooth groove are respectively slidably adjusted with the outer side walls of the two driving rods 350. A plurality of convex blocks are fixedly connected to the inner side wall of any one of the toothed rings 331, and a plurality of grooves are formed on the outer side wall of any one of the driving rods 350. The convex blocks are slidably clamped inside the adjacent grooves. A driving box 360 is fixedly connected to one side of the U-shaped plate 100, and two driving motors are arranged inside the driving box 360. The motor shafts of the two driving motors are respectively fixedly connected to one end of the two driving rods 350. An annular card strip is fixedly connected to one side of one of the tape carriers 370 on any one of the moving components, and an annular moving groove is formed on the other side of the other tape carrier 370. The annular card strip is slidably clamped inside the adjacent moving groove. The cross-section of any one of the rubber belts 371 is V-shaped.

[0041] During specific implementation, before use, two tape cartridges 370 that are respectively located on two adjacent moving components and are close to each other are connected together by snapping the annular clamping strips into the moving grooves. The annular clamping strips can rotate inside the snapped-in moving grooves. The two guide wheels 320 on any one driving component are both frustum-shaped. In the initial state, the rubber belts 371 on multiple moving components are all in a V shape. Then, the cut pieces can naturally fall into the depressions formed by the rubber belts 371. Then, the vibration motor is started, so that the cut pieces that may be stacked together are naturally scattered under the vibration state and all fall into the depressions formed by the adjacent rubber belts 371. The toothed rings 331 and the annular card slots on the multiple driving components on any one rod body 310 have different specifications. Any one driving component is clamped by two adjacent toothed rings 331 and the driving rod 350 to keep it vertical. Then, two driving motors are started to drive the two driving rods 350 to rotate, so that the driving rods 350 drive the toothed rings 331 sleeved on themselves to rotate synchronously. Thus, the toothed rings 331 drive the adjacent ring bodies 330 to rotate, and the ring bodies 330 drive the adjacent guide wheels 320 to rotate synchronously through the guide rails 340 and the U-shaped blocks 321. Thus, multiple driving components rotate synchronously, and the moving speeds of the moving components on each driving component are different due to the different specifications of the toothed rings 331, so that the multiple mutually snapped-together moving components have different rotation speeds, and the cut pieces carried on the moving components are staggered, so that the cut pieces are separated more scattered, which is convenient for the vision inspection equipment to detect, and is convenient for the user to manually remove the unqualified products according to the detection results.

[0042] As Figure 4 and Figure 6 shown, in this embodiment, any one driving component is provided with a deployment mechanism 400. The deployment mechanism 400 includes:

[0043] A pressing block 410, two sleeve rings 420 and two connecting plates 430. The pressing block 410 is located between two adjacent ring bodies 330. Two pull rods 411 are rotatably connected to both ends of the pressing block 410. Clamping rods 421 are fixedly sleeved on the inner side walls of the two sleeve rings 420. Any one clamping rod 421 is slidably clamped between two adjacent ring bodies 330. The outer side walls of the two sleeve rings 420 are respectively rotatably connected to one ends of the two pull rods 411. One sides of the two connecting plates 430 are respectively fixedly connected to the outer side walls of the two sleeve rings 420. Two support arms 431 are rotatably connected to both ends of any one connecting plate 430. The four support arms 431 are respectively rotatably connected to the four U-shaped blocks 321 on two adjacent guide wheels 320. Pressing rods 440 are arranged on one sides of the two rod bodies 310. A jack is opened on one side of any one pressing block 410. The inner side wall of the jack on the pressing block 410 located in the middle of any one rod body 310 is fixedly sleeved with the outer side wall of the adjacent pressing rod 440, and the inner side wall of the jack on other pressing blocks 410 is slidably sleeved with the outer side wall of the adjacent pressing rod 440.

[0044] During specific implementation, after the cut herbs carried on multiple moving components are staggered, the two pressure rods 440 are moved towards the adjacent rod bodies 310, causing the pressure rods 440 to drive multiple adjacent pressure blocks 410 to move synchronously towards the adjacent rod bodies 310. As a result, the pressure blocks 410 press the two adjacent collars 420 to move away from each other through the pull rods 411. Then, the collars 420 drive the connecting plate 430 to move, and the connecting plate 430 drives the two U-shaped blocks 321 in the adjacent guide rails 340 to move away from each other through the support arms 431. Thus, the two guide wheels 320 on the same driving component move away from each other, causing the two guide wheels 320 to pull the rubber belt 371 on the adjacent moving component. The rubber belt 371, which is initially in a V shape, is straightened, thereby widening any moving component. The cut herbs carried on the moving component have a greater spacing due to the widening of the moving component, facilitating detection by the vision inspection device. The cut herbs inside the depression of the rubber belt 371 are naturally flattened as the depression is straightened, thus facilitating detection by the vision inspection device. The driving components in the middle of the two rod bodies 310 only widen and their positions remain unchanged, and other driving components can slide naturally. When it is necessary to restore the moving component, the two pressure rods 440 can be reset, causing the two guide wheels 320 on all the driving components on the rod bodies 310 to come into contact with each other again, and multiple moving components are automatically restored. The driving components that have moved in position can be naturally pulled back to their original positions by the multiple restored moving components connected together. The tape 370 is made of a rubber material with a relatively high hardness. After the tape 370 is sleeved on the two guide wheels 320, its opposite sides can remain parallel to each other and are not easily deformed.

[0045] Embodiment 2

[0046] On the basis of Embodiment 1, the connection bolts 312 are provided to facilitate the use by the user.

[0047] As Figure 3 and Figure 6 shown, in this embodiment, a plurality of return springs 422 are fixedly connected between any one of the clamping rods 421 and the adjacent guide rail 340. Rotating rings 311 are rotatably sleeved at both ends of any one of the rod bodies 310. A support plate is fixedly connected to one side of any one of the rotating rings 311. A connection bolt 312 is rotatably connected to one side of any one of the support plates. Threaded rings are fixedly connected to both ends of any one of the pressure rods 440, and the two threaded rings on any one of the pressure rods 440 are screwed with the two connection bolts 312 on the adjacent rod bodies 310.

[0048] During specific implementation, manually rotate the connection bolt 312 to drive the adjacent pressure rod 440 to move towards the adjacent rod body 310. When it is necessary to restore the moving component, the connection bolt 312 can be rotated to reset the two pressure rods 440. The multiple return springs 422 can generate a certain thrust on the adjacent pressure rod 440, causing the threaded ring on the pressure rod 440 to closely abut against the thread of the adjacent connection bolt 312, so that the threaded ring is not easily loosened due to the vibration of the vibration motor.
