Description

Technical Field

[0001] This invention relates to the field of barcode scanning technology, specifically to an automatic barcode scanning and classification device for tracing the origin of traditional Chinese medicine. Background Technology

[0002] Chinese medicinal materials are usually transported in woven bags, with identification codes affixed to the outside of the bags. Since the outer side of the woven bag is round after being filled with medicinal materials, people need to manually adjust the position of the woven bag so that the side with the identification code faces the scanning device for effective scanning.

[0003] Meanwhile, because woven bags are soft, wrinkles easily appear on their outer side after the raw materials of Chinese medicinal herbs are packed inside. Furthermore, the wrinkles on the outer side of the woven bag are irregular. If wrinkles appear where the identification code is affixed on the outer side of the woven bag, it can easily lead to scanning failure. The wrinkles need to be manually smoothed out before the scanning can be completed normally.

[0004] Currently, in order to scan the identification codes on the outside of woven bags in a normal and effective manner, staff need to expend a lot of physical labor during the scanning process, and the scanning efficiency is relatively low, making it difficult to complete the automatic scanning and classification of Chinese medicinal materials in the process of tracing their origin.

[0005] Therefore, how to reduce the physical labor intensity of staff in the process of scanning and identifying codes, and how to improve the efficiency of scanning and classifying codes, so as to complete the automatic scanning and classification of Chinese medicinal materials in the process of tracing the origin of Chinese medicinal materials, are problems that need to be solved by those skilled in the art. Summary of the Invention

[0006] To address the issues of high physical labor intensity and low efficiency in barcode scanning and classification during the traceability of Chinese medicinal materials, this invention provides an automatic barcode scanning and classification device for traceability of Chinese medicinal materials.

[0007] The technical solution of this invention is as follows:

[0008] This invention provides an automatic barcode scanning and sorting device for tracing traditional Chinese medicine, including a frame. A first conveyor belt is provided on the upper surface of the frame, capable of conveying woven bags containing traditional Chinese medicine. Symmetrically arranged first vertical plates are provided on the outer sides of the first conveyor belt, and the first vertical plates are fixedly connected to the upper surface of the frame. Curved grooves are formed on the opposing inner surfaces of the two first vertical plates. A slider assembly is fitted inside the curved groove, and a barcode scanner is mounted on the slider assembly. A first transmission assembly is provided between the slider assembly and the first conveyor belt, enabling the first conveyor belt to drive the slider assembly to slide along the curved groove. A second transmission assembly is provided between the slider assembly and the barcode scanner, enabling the slider assembly to drive the barcode scanner to slide around the outside of the woven bag. The barcode scanner can scan and identify the identification code on the outside of the woven bag containing traditional Chinese medicine.

[0009] Furthermore, a second conveyor belt is provided on the upper surface of the frame at the end of the first conveyor belt. A second vertical plate is symmetrically provided on the outer side of the second conveyor belt. The second vertical plate is fixedly connected to the upper surface of the frame. Several discharge ports are staggered on the two second vertical plates. The discharge ports are connected to an external conveying device for sorting. An electric push rod is installed on the second vertical plate opposite to each discharge port. The protruding end of the electric push rod passes through the side wall of the second vertical plate. A push plate is fixedly installed at the protruding end of the electric push rod.

[0010] Furthermore, the slider assembly includes a curved slide groove, inside which a first slider is fitted. Two first rollers, rotatably connected to the curved slide groove, are provided on both the front and rear sides of the first slider. The two first rollers are fitted inside the curved slide groove. The inner surface of the first slider is arc-shaped, and an arc-shaped slide groove is formed along its inner surface on the upper surface of the first slider. An annular groove communicating with the arc-shaped slide groove is formed on the inner surface of the first slider. A second slider is slidably connected inside the arc-shaped slide groove. A mounting seat, fixedly connected to the side of the second slider, is provided inside the annular groove. One end of the mounting seat near the center of the arc of the first slider is fixedly connected to a barcode scanner.

[0011] Furthermore, the first transmission component includes a first slider, the left end of which is provided with a ring buckle fixedly connected thereto, and a first elastic pull rope is fixedly bound inside the ring buckle; the power input shaft of the first conveyor belt is located on its front side, the rear side of the first conveyor belt is in a suspended state, the rear side of the first conveyor belt is provided with a transmission column fixedly connected thereto, and the other end of the first elastic pull rope is rotatably fitted on the outside of the transmission column.

[0012] Furthermore, the second transmission component includes a second slider, and a third elastic pull rope is fixedly connected to the right side of the second slider near its upper end. One end of the third elastic pull rope is fixedly connected to the right side of the second slider near its upper end, and the other end of the third elastic pull rope is fixedly connected to the inner side of the first vertical plate located on the rear side of the frame.

[0013] Furthermore, the outer side of the third elastic pull rope is provided with several second pulleys that are slidably connected to it. The second pulleys are fixedly installed in a ring on the upper surface of the first slider near its inner side. The upper surface of the rear part of the first slider is provided with a third pulley that is fixedly connected to it near its left end. The third pulley is slidably connected to the third elastic pull rope. The outer side of the third elastic pull rope near the end that is fixedly connected to the inner side of the first vertical plate is provided with a positioning ring. The positioning ring is fixedly installed on the upper surface of the first slider near its rear left end.

[0014] Furthermore, the second slider is provided with a second elastic pull rope fixedly connected to the left side near its upper end. One end of the second elastic pull rope is fixedly connected to the left side of the second slider near its upper end, and the other end of the second elastic pull rope is provided with an elastic winding device. The elastic winding device is fixedly installed on the first slider. The elastic winding device can automatically wind the second elastic pull rope into the inside of the elastic winding device when the second elastic pull rope is not subjected to external force. The upper surface of the front part of the first slider is provided with a first pulley near its left end, and the outer side of the first pulley is slidably connected to the outer side of the second elastic pull rope.

[0015] Furthermore, the mounting base is symmetrically provided with two first support rods fixedly connected to it on its outer side. The end of the first support rod is provided with a second support rod hinged to it. A torsion spring is provided at the hinge connection between the end of the first support rod and the second support rod. The outer end of the second support rod is provided with an electric telescopic rod fixedly connected to it. The end of the electric telescopic rod is provided with a pressure roller fixedly connected to it. The outer side of the electric telescopic rod is provided with a third support rod fixedly connected to it. The end of the third support rod is provided with a second roller fixedly connected to it.

[0016] Furthermore, a controller electrically connected to a barcode scanner is fixedly installed on the outer side of the first vertical plate. The barcode scanner can scan and identify the information of the identification code on the outside of the Chinese herbal medicine woven bag and convert it into an electrical signal to be transmitted to the controller. The controller is also electrically connected to the first conveyor belt, the second conveyor belt, the electric push rod, and the electric telescopic rod. The controller can control the operation of the first and second conveyor belts, as well as the extension and retraction of the electric push rod and the electric telescopic rod. The controller can control the corresponding electric push rod to extend at an appropriate time point according to the scanning result of the barcode scanner.

[0017] Furthermore, the inner side of the first slider and its left end are provided with an arc-shaped transition chamfer.

[0018] The beneficial effects achieved by this invention are as follows:

[0019] When using this invention for automatic scanning and sorting of Chinese medicinal materials, the left end of the invention is first placed at the end of the existing external conveyor device. This allows the existing external conveyor device to transfer the woven bags containing the Chinese medicinal materials one by one to the first conveyor belt of this invention at a set speed. Then, the front end of the external conveyor device used for sorting is placed one by one outside the discharge port. This allows the controller to control the corresponding electric push rod to extend and push the woven bags containing the Chinese medicinal materials from the discharge port onto the external conveyor device used for sorting. This design increases the automation level of Chinese medicinal materials in the scanning and traceability sorting process, improving the efficiency of scanning and sorting while reducing the physical labor intensity of the staff.

[0020] When the existing external conveying device conveys the woven bags containing Chinese medicinal materials one by one to the outside of the first conveyor belt of this invention at a set speed, the controller starts the first conveyor belt. The first conveyor belt will convey the woven bags containing Chinese medicinal materials to the right. At the same time, the first conveyor belt will drive the transmission column to move to the right synchronously. When the first conveyor belt conveys the woven bags containing Chinese medicinal materials to the center of the inner arc-shaped side of the first slider, the transmission column will promptly pull the first elastic rope to drive the first slider to move to the right simultaneously. The third elastic pull rope will pull the second slider to slide along the arc-shaped groove. At the same time, the controller will turn on the barcode scanner within a set time. The barcode scanner will follow the mounting base and the second slider to slide along the arc-shaped groove on the outside of the woven bag containing Chinese medicinal materials. Since the barcode scanner emits divergent scanning light when in use, it can scan and identify the identification code at any position on the outside of the woven bag containing Chinese medicinal materials. This can save the staff from adjusting the orientation of the identification code during the barcode scanning process and also save the staff's physical exertion during the barcode scanning process.

[0021] As the second slider slides along the arc-shaped groove, the first support rod, which is fixedly connected to it on the outside of the mounting base, moves the second support rod. The second support rod moves the electric telescopic rod and the third support rod. The third support rod moves the second roller to slide on the inner side and left end face of the first slider. When both second rollers are on the inner side of the first slider at the same time, the third support rod pushes the electric telescopic rod to the outer side of the woven bag. Then, by controlling the electric telescopic rod to extend to an appropriate length, the pressure roller presses against the outer side of the woven bag. The damping of the left pressure roller is less than that of the right pressure roller. As the first slider slides to the right, it moves obliquely upward with the increase in the height of the curved groove, causing the second support rod to move the electric telescopic rod and the pressure roller obliquely upward. In this way, when the two pressure rollers press against the outer side of the woven bag, they can smooth out both the horizontal and vertical wrinkles on the outer side of the woven bag, so that the barcode scanner can scan the identification code normally.

[0022] When the first slider moves to the right, the two first rollers on the front and rear sides of the first slider roll inside the curved chute. As the two first rollers roll, they cause the first slider to swing accordingly with the rise and fall of the curved chute. When the first slider is on the far left, it is relatively close to a horizontal position. When the first slider is on the far right, it is in an inclined position with the left end lower than the right end. When the first slider is relatively close to a horizontal position, it can ensure that the woven bag containing Chinese medicinal materials enters the first conveyor belt smoothly. When the first slider is in an inclined position with the left end lower than the right end, it can ensure that the woven bag containing Chinese medicinal materials is smoothly transported from the first conveyor belt to the second conveyor belt. This design ensures the feasibility of the invention in use.

[0023] In summary, this invention, through its ingenious transmission structure, transforms the linear movement of the first conveyor belt into various forms of motion. This enables the barcode scanner to scan and identify the identification codes on the outside of woven bags containing medicinal materials, and also allows the scanner to smooth out wrinkles on the outside of the bags during the scanning process. This reduces the physical labor intensity of staff during barcode scanning and improves the efficiency of barcode sorting. It achieves the goal of automatically scanning and sorting medicinal materials during the traceability process, making it highly suitable for use in large-scale medicinal material distribution centers for categorizing and tracing medicinal materials.

[0030] like Figures 1-7As shown, the present invention provides an automatic scanning and sorting device for tracing the origin of traditional Chinese medicine, including a frame 1. A first conveyor belt 2 is installed on the upper surface of the frame 1 near the middle of its left end. The power input shaft of the first conveyor belt 2 is located on its front side. The rear side of the first conveyor belt 2 is suspended. The front and rear sides of the first conveyor belt 2 are provided with first vertical plates 3 fixedly connected to the upper surface of the frame 1. The inner sides of the two first vertical plates 3 are provided with curved grooves 4 facing each other. The left end of the curved groove 4 is low, the right end is high, and the middle is inclined. A first slider 5 is installed inside the curved groove 4. The first slider 5 will move along the curved groove 4 under the action of external force.

[0031] like Figure 1 , 2 As shown, a second conveyor belt 6 is installed on the upper surface of the frame 1 near the middle of its right end. Second vertical plates 7, fixedly connected to the upper surface of the frame 1, are provided on the front and rear sides of the second conveyor belt 6. Several discharge ports 8 are staggered on the two second vertical plates 7. The discharge ports 8 are connected to an external conveying device (not shown in the figure) used for sorting. An electric push rod 9 is installed on the second vertical plate 7 opposite to each discharge port 8. The protruding end of the electric push rod 9 passes through the side wall of the second vertical plate 7, and a push plate 10 is fixedly installed at the protruding end of the electric push rod 9. When the second conveyor belt 6 transports woven bags containing Chinese medicinal materials (such as...)... Figure 1 (As shown by the dashed line) The material is conveyed to the corresponding outlet 8. The corresponding electric push rod 9 is then extended, and the electric push rod 9 will drive the push plate 10 to push the woven bag containing the Chinese medicinal materials from the outlet 8 to the external conveying device.

[0032] like Figure 6 As shown, the first slider 5 has two first rollers 11 rotatably connected to the curved groove 4 on both its front and rear sides. Figure 3 , 4 As shown, two first rollers 11 are fitted together inside the curved slide groove 4. The left end of the first slider 5 is provided with a ring buckle 12 fixedly connected to it. A first elastic pull rope 13 is fixedly bound inside the ring buckle 12. Figure 5 As shown, the rear side of the first conveyor belt 2 is provided with a transmission column 14 fixedly connected thereto. The other end of the first elastic pull rope 13 is rotatably fitted on the outside of the transmission column 14. When the first conveyor belt 2 moves to the right, it will drive the transmission column 14 to move to the right in sync with it. The transmission column 14 will pull the first elastic pull rope 13 to drive the first slider 5 to move to the right at the same time. When the transmission column 14 moves to the right with the first conveyor belt 2 to the limit position, the transmission column 14 will continue to move to the left with the first conveyor belt 2 to the limit position. At the same time, it will also pull the first elastic pull rope 13 to drive the first slider 5 to move to the left, thus completing the automatic reset of the first slider 5. This enables the invention to run automatically and continuously during use.

[0033] like Figure 3 , 4 As shown, the inner surface of the first slider 5 is arc-shaped, and an arc-shaped groove 15 is formed on the upper surface of the first slider 5 along its inner surface, as shown. Figure 6 As shown, the inner surface of the first slider 5 is provided with an annular groove 16 that communicates with the arc-shaped sliding groove 15, such as... Figure 7 As shown, the interior of the arc-shaped groove 15 is provided with a second slider 17 that is slidably connected thereto. The interior of the annular groove 16 is provided with a mounting seat 18 that is fixedly connected to the side of the second slider 17. A barcode scanner 19 is fixedly installed at one end of the mounting seat 18 near the center of the arc of the first slider 5. The second slider 17 and the mounting seat 18 can drive the barcode scanner 19 to slide along the arc-shaped groove 15, thereby driving the barcode scanner 19 to move spirally around the outside of the woven bag containing Chinese medicinal materials, so as to realize the effective scanning and identification of the identification code on the outside of the woven bag containing Chinese medicinal materials by the barcode scanner 19.

[0034] like Figure 3 , 4 As shown in Figure 7, a second elastic pull rope 20 is fixedly connected to the left side of the second slider 17 near its upper end. One end of the second elastic pull rope 20 is fixedly connected to the left side of the second slider 17 near its upper end, and the other end of the second elastic pull rope 20 is provided with an elastic winding device 22. The elastic winding device 22 is fixedly installed on the first slider 5. The elastic winding device 22 can automatically wind the second elastic pull rope 20 inside the elastic winding device 22 when the second elastic pull rope 20 is not subjected to external force. The structural principle of the elastic winding device 22 is similar to that of a common measuring tape. It belongs to the prior art, and its structural principle will not be described in detail here. A first pulley 23 is provided on the upper surface of the front part of the first slider 5 near its left end. The outer side of the first pulley 23 is slidably connected to the outer side of the second elastic pull rope 20. The first pulley 23 can ensure that the elastic winding device 22 winds the second elastic pull rope 20 more smoothly.

[0035] like Figure 3 , 4 As shown, a third elastic pull rope 21 is fixedly connected to the right side of the second slider 17 near its upper end. One end of the third elastic pull rope 21 is fixedly connected to the right side of the second slider 17 near its upper end. Figure 1 As shown, the other end of the third elastic pull rope 21 is fixedly connected to the inner side of the first vertical plate 3 located on the rear side of the frame 1, as shown. Figure 6As shown, the outer side of the third elastic pull rope 21 is provided with several second pulleys 24 that are slidably connected to it. The second pulleys 24 are fixedly installed in a ring on the upper surface of the first slider 5 near its inner side. The upper surface of the rear part of the first slider 5 is provided with a third pulley 25 that is fixedly connected to it near its left end. The third pulley 25 is slidably connected to the third elastic pull rope 21. The outer side of the third elastic pull rope 21 near the end that is fixedly connected to the inner side of the first vertical plate 3 is provided with a positioning ring 34. The positioning ring 34 is fixedly installed on the upper surface of the first slider 5 near its rear left end. When the first slider 5 moves towards... When moving to the right, the third elastic pull rope 21 will pull the second slider 17 to slide along the arc-shaped groove 15. The second pulley 24 can ensure that the third elastic pull rope 21 pulls the second slider 17 more smoothly, and can also prevent the third elastic pull rope 21 from entering the annular space inside the first slider 5 and affecting the operation of other components. The positioning ring 34 can prevent the third elastic pull rope 21 from sliding out of the groove of the third pulley 25 during the movement. This design further ensures the reliability of the third elastic pull rope 21 pulling the second slider 17, and also ensures the stability of the performance of the present invention.

[0036] like Figure 3 , 4 As shown in Figure 7, two first support rods 26 are symmetrically fixedly connected to the outer side of the mounting base 18. The end of the first support rod 26 is provided with a second support rod 27 hinged to it. A torsion spring is provided at the hinge connection between the end of the first support rod 26 and the second support rod 27. When the second support rod 27 is not subjected to external force, the torsion spring can cause the two symmetrical second support rods 27 to open outwards relative to each other. An electric telescopic rod 28 is fixedly connected to the outer end of the second support rod 27. A pressure roller 29 is fixedly connected to the end of the electric telescopic rod 28. A third support rod 30 is fixedly connected to the outer side of the electric telescopic rod 28. A second roller 31 is fixedly connected to the end of the third support rod 30. An arc-shaped transition chamfer 32 is provided between the inner side of the first slider 5 and its left end. The transition chamfer 32 can allow the second roller 31 to slide smoothly between the inner side of the first slider 5 and its left end face.

[0037] like Figure 7As shown, when the second slider 17 is located at its extreme position near the left end of the front side of the first slider 5 inside the arc-shaped groove 15, the torsion spring causes the second support rod 27 on the left side to open outwards until the second roller 31 at the end of the third support rod 30 is pressed against the left end face of the first slider 5. When the first slider 5 moves to the right, causing the third elastic pull rope 21 to pull the second slider 17 to slide to the left along the arc-shaped groove 15, the second slider 17 will drive the mounting base 18 and the first support rod 26 to move to the left. The first support rod 26 will drive the second support rod 27 to move to the left. When the second support rod 27 moves to the left, it will cause the electric telescopic rod 28 and the third support rod 30 to move to the left. The third support rod 30 will drive the second roller 31 to enter the inner side of the first slider 5 along the left end face of the first slider 5 through the transition chamfer 32. Thus, after the electric telescopic rod 28 is extended, the pressure roller 29 can press against the outer side of the woven bag. Figure 7 In the indicated state, the damping of the left pressure roller 29 is designed to be less than that of the right pressure roller 29. This way, when the pressure roller 29 rolls on the outer side of the woven bag, the speed difference between the two rollers can smooth out the wrinkles on the outer side of the woven bag. Furthermore, as the first slider 5 slides to the right, it moves obliquely upward with the increase in the height of the curved groove 4, thereby causing the second support rod 27 to drive the electric telescopic rod 28 and the pressure roller 29 to move obliquely upward. Thus, when the two pressure rollers 29 press over the outer side of the woven bag, they can smooth out both the horizontal and vertical wrinkles on the outer side of the woven bag, so that the barcode scanner 19 can scan the identification code normally.

[0038] like Figure 4 As shown, when the second slider 17 is located at the extreme position inside the arc-shaped groove 15 near the left end of the rear side of the first slider 5, the torsion spring causes the second support rod 27 located on the left to open outwards relative to each other until the second roller 31 at the end of the third support rod 30 is pressed against the left end face of the first slider 5. When the identification code on the outside of the woven bag is at the leftmost position, the opening of the second support rod 27 relative to each other can prevent the electric telescopic rod 28 and the pressure roller 29 from blocking the scanner 19 from scanning the identification code, ensuring that the scanner 19 effectively scans the identification code.

[0039] like Figure 1 , 2As shown, a controller 33, which is electrically connected to a barcode scanner 19, is fixedly installed on the outer side of the first vertical plate 3 located at the front of the frame 1. The barcode scanner 19 can scan and identify the information of the identification code on the outside of the Chinese herbal medicine woven bag and convert it into an electrical signal, which is then transmitted to the controller 33. The controller 33 is also electrically connected to the first conveyor belt 2, the second conveyor belt 6, the electric push rod 9, and the electric telescopic rod 28. The controller 33 can control the operation of the first conveyor belt 2 and the second conveyor belt 6, as well as the extension and retraction of the electric push rod 9 and the electric telescopic rod 28. According to the scanning result of the barcode scanner 19, the controller 33 can control the corresponding electric push rod 9 to push out at an appropriate time, thereby pushing the corresponding woven bag from the second conveyor belt 6 to the external conveying device to complete the automatic sorting of woven bags containing Chinese herbal medicine raw materials.

[0040] In summary, when using this invention for automatic scanning and sorting of Chinese medicinal materials, the left end of the invention is first placed at the end of the existing external conveying device, so that the existing external conveying device can convey the woven bags containing Chinese medicinal materials one by one to the first conveyor belt 2 of the invention at a set speed. Then, the front end of the external conveying device for sorting is placed one by one outside the discharge port 8, so that the controller 33 can control the corresponding electric push rod 9 to extend and push the woven bags containing Chinese medicinal materials from the discharge port 8 to the external conveying device for sorting. This design can increase the automation level of Chinese medicinal materials in the scanning and traceability sorting process, which not only improves the efficiency of scanning and sorting, but also reduces the physical labor intensity of the staff.

[0041] When the existing external conveying device conveys the woven bags containing Chinese medicinal materials one by one to the outside of the first conveyor belt 2 of this invention at a set speed, the controller 33 starts the first conveyor belt 2. The first conveyor belt 2 will convey the woven bags containing Chinese medicinal materials to the right. At the same time, the first conveyor belt 2 will drive the transmission column 14 to move to the right synchronously. When the first conveyor belt 2 conveys the woven bags containing Chinese medicinal materials to the center of the arc-shaped inner side of the first slider 5, the transmission column 14 will pull the first elastic rope 13 in time, driving the first slider 5 to move to the right at the same time. At the same time as the first slider 5 moves to the right, the third elastic rope 21 will pull the second slider 17 to slide along the arc-shaped slide groove 15. At the same time, the controller 33 will turn on the barcode scanner 19 within a set time. The barcode scanner 19 will slide along the arc-shaped slide groove 15 on the outside of the woven bags containing Chinese medicinal materials, following the mounting base 18 and the second slider 17. Since the barcode scanner 19 emits divergent scanning light (such as...) during use... Figure 7 As shown by the dashed line, this enables the scanning and recognition of identification codes located at any position on the outside of woven bags containing Chinese medicinal materials. This saves staff from adjusting the orientation of the identification codes during the scanning process and also reduces their physical exertion.

[0042] As the second slider 17 slides along the arc-shaped groove 15, the first support rod 26, which is fixedly connected to the outer side of the mounting base 18, will drive the second support rod 27 to move. The second support rod 27 will cause the electric telescopic rod 28 and the third support rod 30 to move. The third support rod 30 will drive the second roller 31 to slide on the inner side and left end face of the first slider 5. When both second rollers 31 are simultaneously on the inner side of the first slider 5, the third support rod 30 will push the electric telescopic rod 28 to the outer side of the woven bag. Then, by controlling the electric telescopic rod 28 to extend to an appropriate length through the controller 33, the pressure roller 29 can be pressed against the outer side of the woven bag. Figure 7 In the indicated state, the damping of the left pressure roller 29 when rotating is less than that of the right pressure roller 29. Furthermore, as the first slider 5 slides to the right, it moves obliquely upward as the height of the curved groove 4 increases. This causes the second support rod 27 to drive the electric telescopic rod 28 and the pressure roller 29 to move obliquely upward. Thus, when the two pressure rollers 29 press over the outer side of the woven bag, they can smooth out both the horizontal and vertical wrinkles on the outer side of the woven bag, making it easier for the barcode scanner 19 to scan the identification code normally.

[0043] like Figure 1 , 2 As shown, when the first slider 5 moves to the right, the two first rollers 11 on the front and rear sides of the first slider 5 will roll inside the curved groove 4, and the two first rollers 11 will cause the first slider 5 to swing accordingly with the ups and downs of the curved groove 4, as shown. Figure 1 As shown, when the first slider 5 is located at the far left, the first slider 5 is relatively close to being horizontal, as... Figure 2 As shown, when the first slider 5 is located on the far right, it will be in an inclined position with the left end lower than the right end. When the first slider 5 is relatively close to being horizontal, it can ensure that the woven bag containing Chinese medicinal materials enters the first conveyor belt 2 smoothly. When the first slider 5 is in an inclined position with the left end lower than the right end, it can ensure that the woven bag containing Chinese medicinal materials is smoothly transported from the first conveyor belt 2 to the second conveyor belt 6. This design ensures the feasibility of the invention in use.

[0044] In summary, this invention, through its ingenious transmission structure, transforms the linear movement of the first conveyor belt 2 into various forms of motion. This enables the barcode scanner 19 to scan and identify the identification codes on the outside of the woven bags containing Chinese medicinal materials, and also allows the barcode scanner 19 to smooth out the wrinkles on the outside of the woven bags during the scanning process. This reduces the physical labor intensity of staff during barcode scanning and improves the efficiency of barcode sorting. It achieves the goal of automatically scanning and sorting Chinese medicinal materials during the traceability process, making it highly suitable for use in large-scale Chinese medicinal material distribution centers for categorizing and tracing Chinese medicinal materials, and has significant potential for widespread application.

[0045] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
