Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine production equipment technology, specifically to an automatic foreign object removal device for traditional Chinese medicine decoction pieces. Background Technology

[0002] Traditional Chinese medicine (TCM) decoction pieces are block-shaped products made from raw medicinal materials through standardized cleaning, cutting, or processing. This process alters the original form of the medicinal materials, reduces toxicity, moderates medicinal properties, and enhances efficacy while facilitating the extraction of active ingredients. It is the most commonly used and distinctive form of medicine in TCM diagnosis and prescription, and also an important raw material for the production of prepared Chinese medicines. During the preparation of TCM decoction pieces, some foreign objects may be mixed in, requiring removal before packaging. Current TCM decoction piece packaging lines rely on manual visual inspection or metal detectors, which carries the risk of missing non-metallic foreign objects such as hair and plastic. With the rise of AI algorithms, methods have emerged that establish a database of medicinal material morphology and then use image registration technology to locate and remove foreign objects. However, these detection methods are usually single-channel, leading to raw material stacking and difficulty in detecting internal foreign objects. A new type of detection equipment is needed to solve these problems. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an automatic foreign object removal device for Chinese herbal medicine slices, comprising a conveyor belt with its tail end extending into a housing. The housing is divided into a slice channel and a foreign object channel by a pair of partitions. The bottom surface of the partitions is fitted with the upper surface of the conveyor belt. A viewing component is provided at the entrance end of the slice channel, and a camera component is mounted above the slice channel. A discharge mechanism is connected to the exit end of the slice channel. Each pair of channels is connected by a notch in the partition, at which two sets of lane-changing components are provided. The two lane-changing components are located behind the viewing and camera components, respectively. The two ends of the lane-changing and camera components extend out from windows on both sides of the housing and are vertically slidably connected to threaded rods below the windows. Each component is electrically connected to a controller.

[0004] Furthermore, the fluoroscopic assembly includes an X-ray source facing the detector. The X-ray source and the detector are respectively installed on the two side walls at the entrance end of the slice channel, and the X-ray source and detector's beams are connected from the top.

[0005] Furthermore, the imaging components include CCD cameras, with the CCD camera lens facing vertically downwards toward the upper surface of the conveyor belt. The CCD camera wiring harness is connected from the top, and each CCD camera is mounted on a lifting base. The waist holes on the end plates of the lifting base are vertically slidably connected to the central threaded rod and secured with nuts.

[0006] Furthermore, the lane-changing assembly includes a cylinder seat. The waist hole on the end plate of the cylinder seat is vertically slidably connected to the threaded rods on both sides and then fastened by nuts. The cylinder seat has several rejecters built in. The rejecter wiring harness passes out from one side of the cylinder seat. The rejecter drives the output rod to extend and retract through the built-in electromagnet. The end of the output rod is connected to the vertical shaft of the push plate. The shaft body is slidably connected to the waist hole on the bottom surface of the cylinder seat. The push plate is located on one side of the slice channel. When the output rod retracts, the push plate moves towards the notch of the surrounding plate.

[0007] Furthermore, the discharge mechanism includes a ramp, the upper end of which is connected to the outlet end of each beverage slice channel, the lower end of which is located above the discharge belt, the discharge belt is covered with a protective cover, and a waste box is provided below the bottom of the machine box, with the opening of the waste box located below the outlet end of the foreign matter channel.

[0008] Furthermore, the conveyor belt is equipped with a screening mechanism at its head end. The screening mechanism includes an infeed belt, and the output end of the infeed belt is equipped with a height-limiting span. The output end of the infeed belt is connected to the uppermost screen plate of the screen plate box. Each screen plate is distributed in a stepped manner inside the screen plate box. The shafts at both ends of the screen plate are hinged to the side wall of the screen plate box and fastened with nuts. The bottom surface of the screen plate box is connected to the top surface of the screen vibration frame through a spring seat. The hinge seat on the top surface of the screen vibration frame is rotatably connected to the camshaft. The cam on the camshaft shaft is in contact with the bottom surface of the screen plate box. One end of the camshaft is connected to the screen vibration motor, and the screen vibration motor is installed on the outer side of the hinge seat.

[0009] Furthermore, the controller is installed in the upper electrical control room of the chassis, and the control panel electrically connected to the controller is installed on the outer wall of the chassis.

[0010] The beneficial effects of this invention are as follows: The device uses a screening mechanism to spread the Chinese medicinal herbs flat onto a conveyor belt, which is then divided into multiple pairs of channels. Guided by the inclined surfaces of the surrounding plates, the herbs enter the machine chamber through each channel. The machine chamber has built-in imaging and imaging components that use visible light cameras and X-ray imaging technology to capture images of the raw materials in the channels. AI algorithms compare these images with a database. Foreign objects detected are ejected by a deflector to the foreign object channel and discharged. The remaining qualified herbs continue to enter the discharge belt along the channels. The entire process requires no manual intervention. The multi-channel, dual-image acquisition method allows for the observation of foreign objects both inside and outside the raw materials, improving both detection accuracy and efficiency.

One end of the camshaft 19 is connected to a screen vibration motor 20, which is installed on the outer side of the hinge seat.

[0019] In this embodiment, the tail end of the conveyor belt 1 extends into the housing 2. Windows 204 are opened on both sides of the housing 2, and three threaded rods 205 are located below the windows 204. The housing 2 is divided into a medicinal slice channel 202 and a foreign object channel 203 by a partition plate 201. The bottom surface of the partition plate 201 is fitted with a clearance fit to the upper surface of the conveyor belt 1. A perspective assembly is provided at the entrance end of the medicinal slice channel 202, including an X-ray source 4 facing a detector 5. The X-ray source 4 and detector 5 are respectively installed on the two side walls at the entrance end of the medicinal slice channel 202, and the wiring harnesses of the X-ray source 4 and detector 5 are connected from the top. A camera assembly is mounted above the medicinal slice channel 202, including a CCD camera 6. The camera of the CCD camera 6 is vertically downward facing the upper surface of the conveyor belt 1, and the wiring harness of the CCD camera 6 is connected from the top. Each CCD camera 6 is mounted on a lifting base 7. The waist holes on the end plates of the lifting base 7 are vertically slidably connected to the central threaded rods 205 and secured with nuts.

[0020] In this embodiment, each pair of medicinal slices and foreign matter channels are connected by a notch in the enclosure 201. Two sets of lane-changing components are provided at the notch. The two lane-changing components are located behind the perspective and imaging components, respectively. The lane-changing components include a cylindrical base 8. The waist holes on the end plates of the two cylindrical bases 8 are vertically slidably connected to the threaded rods 205 on both sides and then fastened by nuts. The cylindrical base 8 has several rejecters 9 built in it. The wire harness of the rejecter 9 passes out from one side of the cylindrical base 8. The rejecter 9 drives the output rod 902 to extend and retract through the built-in electromagnet 901. The end of the output rod 902 is connected to the vertical shaft of the push plate 10. The shaft body is slidably connected to the waist hole on the bottom surface of the cylindrical base 8. The push plate 10 is located on one side of the medicinal slice channel 202. When the output rod 902 retracts, the push plate 10 moves toward the notch in the enclosure 201.

[0021] In this embodiment, the wiring harnesses of each component are electrically connected to the controller 3. The controller 3 is installed in the upper electrical control room 206 of the chassis 2. The control panel 301, which is electrically connected to the controller 3, is installed on the outer wall of the chassis 2. The outlet end of the herbal medicine channel 202 is connected to the discharge mechanism, which includes a ramp 11. The upper end of the ramp 11 is connected to the outlet end of each herbal medicine channel 202, and the lower end of the ramp 11 is located above the discharge belt 12.

The opening of the waste box 14 is located below the outlet end of the foreign matter channel 203.

[0022] The working principle of this utility model is as follows:

[0023] The Chinese herbal medicine slices conveyed by the feed belt 15 are initially smoothed by the height-limiting span 1501 and fall onto the uppermost sieve plate 1601. The sieve vibration motor 20 is started, driving the camshaft 19 to rotate. The camshaft 19 repeatedly vibrates the sieve plate box 16. The Chinese herbal medicine slices are sieved layer by layer on each level of sieve plate 1601 and finally fall evenly onto the conveyor belt 1, which then reaches the machine box 2. Guided by the inclined surface of the surrounding plate 201, the Chinese herbal medicine slices are aligned with each slice channel 202 and enter the machine box 2. The X-ray source 4 irradiates the Chinese herbal medicine slices, and the fluoroscopic signal is received by the detector 5 and transmitted to the controller 3 for database comparison. The comparison result is displayed on the control screen 301. When a foreign object is detected, the rejection device 9 is activated. The electromagnet 901 drives the output rod 902 to retract rapidly, and the pusher plate 10 knocks the foreign object into the foreign object channel 203 through the notch in the surrounding plate 201. The remaining Chinese herbal medicine slices on the slice channel 202 continue to pass through the CCD camera 6 for re-inspection and comparison. After all slices pass, they enter the discharge belt 12 via the ramp 11 and are sent to the next process. The protective cover 13 on the discharge belt 12 can prevent secondary contamination after inspection. Foreign objects ejected during the two inspections fall into the waste box 14 through the foreign object channel 203 for collection. During the above process, the height of the imaging and lane-changing components can be adjusted to accommodate different types of Chinese herbal medicine slices.

[0024] This invention requires no manual intervention throughout the entire process and employs a multi-channel dual image acquisition method to observe foreign objects inside and outside the raw materials, thereby improving both detection accuracy and efficiency.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
