Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of thickness measuring equipment, in particular to a thickness automatic measuring device and method for processing of Ligusticum chuanxiong slices. BACKGROUND

[0002] Ligusticum chuanxiong is a commonly used traditional Chinese medicine, and its rhizome is used as medicine, which has the effects of promoting blood circulation and expelling wind to relieve pain, and is widely used in clinical medicine and traditional Chinese medicine preparations. In order to meet the demand for medicine, Ligusticum chuanxiong needs to be processed by slicing, and the rhizome is cut into a certain thickness of decoction pieces.

[0003] During the processing of Ligusticum chuanxiong slices, due to uneven distribution of fibers in the raw material, mechanical stress during slicing and water loss difference during drying, the center of the slice is prone to bulging or the edge is prone to lifting. These irregular shape problems are not individual cases, but common shape defects in the processing link.

[0004] The existing thickness measuring device lacks a targeted pretreatment mechanism and cannot effectively flatten such uneven slices. During detection, the bulging part or the lifted edge of the slice directly contacts the measuring component, causing the measurement point to deviate from the actual plane, resulting in distorted thickness data. At the same time, the conversion of the workstations of the traditional device relies on manual operation, and the connection between the flattening and thickness measuring links is not smooth. This not only prolongs the detection period, but also may cause the shape of the slice to change again due to human intervention. SUMMARY

[0005] The purpose of the present application is to provide a thickness automatic measuring device and method for processing of Ligusticum chuanxiong slices to solve the problems raised in the background.

[0006] To achieve the above purpose, the present application provides the following technical scheme: a thickness automatic measuring device for processing of Ligusticum chuanxiong slices, comprising a thickness measuring table, a support frame fixed at the top end of the thickness measuring table, and an electric telescopic rod fixed longitudinally at the top end of the support frame.

Several friction blocks are fixedly installed at equal angles around the bottom end of the pressure ring.

[0010] Furthermore, a first arc-shaped groove is provided through the inside of the limiting cylinder on the side near each abutment rod, and each abutment rod is connected to the first arc-shaped groove on the corresponding side. A fixing ring is slidably installed through the outside of the side of each abutment rod near the first arc-shaped groove, and a rotating frame is fixedly installed on one side of the fixing ring. The end of the rotating frame away from the fixing ring is rotatably installed on the outside of the top of the limiting cylinder.

[0011] Furthermore, several positioning blocks are fixedly installed on the side of each contact rod near the rangefinder. An auxiliary rod is fixedly installed on the top of each positioning block. The top of the auxiliary rod is slidably installed on the outside of the top of the fixed ring. A return spring is sleeved through the outside of the auxiliary rod. The two ends of the return spring are fixedly installed on the side of the fixed ring and the positioning block, respectively. A first drive motor is fixedly installed on the top of the fixed frame.

[0012] Furthermore, a turntable is fixedly installed on the outer side of the rotating shaft away from the first drive motor. A second arc-shaped groove is provided through the outer side of the turntable near each abutment rod. Each abutment rod is slidably connected to the second arc-shaped groove on the corresponding side.

[0013] Furthermore, the shaping component includes several limiting grooves and a liquid storage tank. The several limiting grooves are equally angled and arranged around the bottom of the hot press plate. The liquid storage tank is fixedly installed through the transmission rod on the outside of the side near the hot press plate. Each limiting groove has an applicator roller on its outside opening end. A positioning frame is provided on one side of the applicator roller.

[0014] Furthermore, the positioning frame has an adhesive guiding channel inside, and the coating roller has a conveying channel through its center.

Several abutment springs are fixedly installed between the piston block and the inner wall of one side of the limiting groove.

[0015] The present invention also provides an operating method for an automated thickness measurement device for processing sliced ​​Ligusticum chuanxiong, comprising the following steps:

[0016] S1: First, the slice of Ligusticum striatum that needs to be measured is placed on the placement platform at the top of the thickness measuring table through the existing intermittent conveying mechanism. Then, the mounting frame and the limiting cylinder are lowered by controlling the electric telescopic rod. At this time, the flattening component at the bottom of the limiting cylinder contacts the slice of Ligusticum striatum to be tested, and flattens the raised center or edge of the slice of Ligusticum striatum to ensure the accuracy of subsequent testing.

[0017] S2: After the slice of Ligusticum chuanxiong to be tested is flattened by the flattening component, the shaping component is controlled to apply a small amount of edible glue to the flattening surface of the slice. The glue penetrates into the cut surface to form an elastic film, which can bind the fiber stress, reduce the shape change of the slice due to the release of internal stress, prevent it from resetting after flattening, and repair micro cracks to prevent crack expansion caused by contact force during the testing process.

[0018] S3: After the slice has been processed by the flattening and shaping components, the electric telescopic rod is controlled to lift the mounting frame and the limiting cylinder a certain distance. Then, the stepper motor is controlled to rotate the limiting cylinder 180 degrees so that the thickness measuring component at the top of the limiting cylinder faces downward. Then, the electric telescopic rod is controlled again to lower the mounting frame and the limiting cylinder so that the thickness measuring component contacts the slice of Ligusticum chuanxiong to be tested, thereby realizing multi-point slice thickness detection.

[0019] S4: After the test is completed, the electric telescopic rod is controlled to lift the mounting frame and the limiting cylinder a certain distance. Then, the stepper motor is controlled to rotate the limiting cylinder 180 degrees to complete the switching of the flattening component and the shaping component facing downwards. After that, the tested slice is transported out through the existing intermittent conveying mechanism, and another slice of Ligusticum chuanxiong is placed on the top of the thickness measuring platform for intermittent cyclic thickness measurement.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. By setting and operating the flattening component, this thickness measuring device can flatten the slices of Ligusticum chuanxiong to a flat state using appropriate pressure and contact methods, thus removing shape obstacles for subsequent testing and avoiding measurement deviations caused by irregular slices from the source. This ensures that the thickness data is accurate and reliable. After the flattening operation is completed, the device drives the limiting cylinder to rotate via a stepper motor, quickly achieving a workstation switch. This allows the thickness measuring component to accurately turn downwards, enabling the connection of the thickness measuring process without manual intervention. This significantly shortens the process transition time and improves the overall testing efficiency. At the same time, the spacing of multiple contact rods can be flexibly adjusted during thickness measurement to ensure that each contact rod can closely fit different areas on the top of the slice, covering more measurement points and reducing errors caused by a single contact point. This also enhances the device's adaptability to slices of different shapes, further ensuring testing accuracy.

[0022] 2. Through the setting and operation of the shaping component, it is possible to effectively prevent the Chuanxiong slices from rebounding and breaking after being flattened. The glue penetrates to the cut surface to form an elastic film, which can bind the fiber stress and reduce the morphological changes caused by the release of internal stress. At the same time, it repairs micro-cracks and avoids crack expansion caused by contact force during the inspection process. In addition, this structure is linked with the flattening mechanism to complete the coating simultaneously during the flattening process without increasing the production cycle. It can reduce waste caused by rebound and breakage and eliminate the need for complicated subsequent processing procedures. While ensuring the stability of product quality, it improves production efficiency. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example 1: Please refer to Figure 1 - Figure 8An automated thickness measurement device for processing sliced ​​Ligusticum chuanxiong includes a thickness measuring platform 1, a support frame 2 fixed to the top of the thickness measuring platform 1, and an electric telescopic rod 3 longitudinally fixed to the top of the support frame 2. An installation frame 6 is fixedly installed at the output end of the electric telescopic rod 3. A data analysis operating table 39 is fixedly installed on the outside of one side of the support frame 2. A limiting cylinder 4 is rotatably installed on one side of the bottom end of the installation frame 6. A flattening component and a shaping component are provided at the bottom end of the limiting cylinder 4, and a thickness measuring component is provided at the top end of the limiting cylinder 4. The flattening component includes a pressure ring 8 and a hot pressure plate 12. The pressure ring 8 is located outside the bottom end of the limiting cylinder 4, and the hot pressure plate 12 is located on one side of the top end of the pressure ring 8. The inner diameter of the pressure ring 8 is larger than the outer diameter of the hot pressure plate 12. The thickness measuring component includes several contact rods 15, which are arranged at equal angles around the outside of one side of the top end of the limiting cylinder 4. A rangefinder 18 is fixedly installed on the outside of the end of each contact rod 15 near the inside of the limiting cylinder 4.

[0037] A placement platform 5 is fixedly installed on the outside of the thickness measuring platform 1 near the top of the limiting cylinder 4. A stepper motor 7 is fixedly installed on the outside of one side of the mounting bracket 6. The output end of the stepper motor 7 is fixedly installed on the outside of one side of the limiting cylinder 4.

[0038] Several guide rods 10 are fixedly installed around the top of the pressure ring 8 at equal angles. Fixing blocks 9 are fixedly installed on the outside of the limiting cylinder 4 near the guide rods 10. The top of each guide rod 10 is slidably installed inside the corresponding fixing block 9. A compression spring 11 is sleeved on the outside of each guide rod 10. The two ends of the compression spring 11 are fixedly installed on the side of the fixing block 9 and the pressure ring 8, respectively.

[0039] A fixed frame 13 is fixedly installed in the middle of the inner part of the limiting cylinder 4. A transmission rod 14 is rotatably engaged in the middle of the inner part of the fixed frame 13. The bottom end of the transmission rod 14 is fixedly installed in the middle of the top of the hot press plate 12. A second drive motor 38 is fixedly installed on one side of the bottom end of the fixed frame 13. The output end of the second drive motor 38 is coaxially fixed with the top end of the transmission rod 14. Several friction blocks 28 are fixedly installed around the bottom end of the pressure ring 8 at equal angles.

[0040] The limiting cylinder 4 has a first arc-shaped groove 40 that is provided through the inside of each abutment rod 15 on the side closest to it. Each abutment rod 15 is connected to the first arc-shaped groove 40 on the corresponding side. A fixing ring 16 is slidably installed through the outside of each abutment rod 15 on the side closest to the first arc-shaped groove 40. A rotating frame 17 is fixedly installed on one side of the fixing ring 16. The end of the rotating frame 17 away from the fixing ring 16 is rotatably installed on the outside of the top of the limiting cylinder 4.

[0041] Each contact rod 15 has several positioning blocks 19 fixedly installed on the side near the rangefinder 18. Each positioning block 19 has an auxiliary rod 20 fixedly installed on its top. The top of the auxiliary rod 20 is slidably installed on the outside of the top of the fixed ring 16. A return spring 21 is sleeved through the outside of the auxiliary rod 20. The two ends of the return spring 21 are fixedly installed on the side of the fixed ring 16 and the positioning block 19, respectively. A first drive motor 22 is fixedly installed on one side of the top of the fixed frame 13. A rotating shaft 23 is rotatably installed through the middle of the top of the limiting cylinder 4. One end of the rotating shaft 23 is coaxially fixed with the output end of the first drive motor 22.

[0042] A turntable 24 is fixedly installed on the outside of the end of the rotating shaft 23 away from the first drive motor 22. A second arc-shaped groove 25 is provided through the outside of the turntable 24 near each abutment rod 15. Each abutment rod 15 and the corresponding second arc-shaped groove 25 are connected through slidingly.

[0043] In this embodiment, firstly, the slice of Ligusticum chuanxiong to be measured is placed on the placement platform 5 at the top of the thickness measuring platform 1 using the existing intermittent conveying mechanism. Then, the electric telescopic rod 3 is controlled to drive the mounting frame 6 and the limiting cylinder 4 to descend. When the limiting cylinder 4 descends to the appropriate position, the flattening component at its bottom contacts the Ligusticum chuanxiong slice and begins to flatten the slice. Firstly, the pressure ring 8, with the cooperation of the guide rod 10, the fixing block 9 and the compression spring 11, acts on the edge of the slice with the elastic force of the compression spring 11 to process the raised part of the edge. At the same time, the transmission rod 14 on one side of the fixing frame 13 drives the heat... The pressure plate 12 flattens the raised center of the slice, thus completing the overall flattening process of the Ligusticum chuanxiong slice. This allows the thickness measuring device to flatten the Ligusticum chuanxiong slice with appropriate pressure and contact method during use, clearing away shape obstacles for subsequent testing and avoiding measurement deviations caused by irregular slices from the source, ensuring the accuracy and reliability of thickness data. At the same time, the friction block 28 at the bottom of the pressure ring 8 can enhance the friction with the slice, ensuring that the pressure ring 8 can stably press the slice on the top of the placement stage 5 when the hot pressure plate 12 rotates, ensuring the stable operation of the shaping component.

[0044] It should also be noted that after the flattening operation is completed, the electric telescopic rod 3 is controlled to lift the mounting frame 6 and the limiting cylinder 4. Then, the stepper motor 7 drives the limiting cylinder 4 to rotate 180 degrees, so that the thickness measuring component at the top faces downward. Then, the electric telescopic rod 3 is controlled to descend again, so that one end of several abutting rods 15 first abuts against the slice surface. As the electric telescopic rod 3 continues to descend (its total extension distance is fixed), the limiting cylinder 4 will continue to move downward. However, the abutting rods 15 cannot move downward synchronously with the limiting cylinder 4 because they are blocked by the slice, and are thus abutted upward. When the abutting rods 15 are lifted, they will drive the positioning block 19 fixed to them to move upward synchronously. The positioning block 19 will then drive the auxiliary rod 20 to slide upward along the fixing ring 16, while compressing the return spring 21 outside the auxiliary rod 20. The fixing ring 16 is limited by the rotating frame 17. To maintain a stable position, ensure that the contact rod 15 only moves longitudinally along the first arc groove 40. During this process, the rangefinder 18 at the top of the contact rod 15 will move upward synchronously with the contact rod 15, and its relative distance to the fixed reference components such as the limiting cylinder 4 or the fixing frame 13 will change. Since the total extension distance of the electric telescopic rod 3 is fixed, that is, the total downward distance of the limiting cylinder 4 from the initial position to the final stop position is a fixed value, and the lifting distance of the contact rod 15 by the slice is exactly equal to the actual thickness of the slice, the rangefinder 18 will detect the change in its distance from the fixed reference component in real time and transmit the data to the data analysis operating table 39. The operating table calculates the distance data corresponding to several contact rods 15 to obtain the thickness values ​​of multiple points of the slice. After integration and processing, the thickness parameters of the slice can be obtained, and accurate thickness measurement is completed.

[0045] It should also be noted that after the test is completed, the electric telescopic rod 3 drives the whole structure to rise, and the stepper motor 7 flips the limiting cylinder 4 again so that the flattening component and the shaping component face downwards. Finally, the tested slice is sent out through the intermittent conveying mechanism and a new slice of Ligusticum chuanxiong is placed to realize intermittent cyclic thickness measurement. This device drives the limiting cylinder 4 to rotate through the stepper motor 7 to quickly realize the workstation switching, so that the thickness measuring component can be accurately turned downwards. The thickness measuring process can be connected without manual intervention, which greatly shortens the process changeover time and improves the overall testing efficiency.

[0046] It should also be noted that during the thickness measurement process, the spacing between the multiple contact rods 15 can be flexibly adjusted. During adjustment, the first drive motor 22 at the top of the fixed frame 13 drives the rotating shaft 23 to rotate, causing the turntable 24 connected to the rotating shaft 23 to rotate synchronously. The second arc-shaped grooves 25 on the turntable 24 are distributed along a specific trajectory, and each contact rod 15 slides through the corresponding second arc-shaped groove 25. When the turntable 24 rotates, the trajectory of the second arc-shaped grooves 25 generates a radial thrust on the contact rods 15, forcing the contact rods... The abutment rod 15 slides along the first arc groove 40 on the limiting cylinder 4. At this time, the fixing ring 16 on the outer side of the abutment rod 15 deflects synchronously with the abutment rod 15 under the support of the rotating frame 17. The auxiliary rod 20 slides along the fixing ring 16 to cooperate with the position adjustment. Finally, the spacing of multiple abutment rods 15 in the radial direction can be flexibly changed, thereby ensuring that each abutment rod 15 can closely fit different areas of the top of the slice, covering more measurement points, reducing the error caused by a single contact point, and enhancing the device's adaptability to slices of different shapes, further ensuring the detection accuracy.

[0047] Example 2: Please refer to Figure 5 , Figure 9 - Figure 11 This embodiment further explains the first embodiment. The shaping component includes several limiting grooves 26 and a liquid storage tank 36. The several limiting grooves 26 are equally angled and arranged around the bottom of the hot press plate 12. The liquid storage tank 36 is fixedly installed through and on the outside of the transmission rod 14 near the hot press plate 12. Each limiting groove 26 has an applicator roller 27 on its outside opening end. A positioning frame 29 is provided on one side of the applicator roller 27. Both ends of the applicator roller 27 are rotatably installed inside one side of the positioning frame 29. A piston block 30 is fixedly installed on one end of the positioning frame 29. The piston block 30 is slidably and sealingly installed inside the limiting groove 26 on the corresponding side.

[0048] The positioning frame 29 has an adhesive guiding channel 31 inside, and the application roller 27 has a conveying channel 32 through the middle of its interior. The conveying channel 32 is connected to the adhesive guiding channel 31. Several discharge ports 33 are arranged at equal angles around the outside of the application roller 27 and the inside of the conveying channel 32. A first one-way valve 34 is fixedly installed between the outside of one side of the piston block 30 and the inside of one side of the adhesive guiding channel 31. A second one-way valve 35 is fixedly installed between the inside of one side of the limiting groove 26 and the inside of the bottom end of the liquid storage tank 36. Several abutment springs 37 are fixedly installed between the piston block 30 and the inner wall of one side of the limiting groove 26.

[0049] In this embodiment, the electric telescopic rod 3 drives the limiting cylinder 4, the pressure ring 8, and the hot press plate 12 to descend for flattening. After descending to a certain position, several applicator rollers 27 at the bottom of the hot press plate 12 rise due to the resistance of the slice, thereby driving the positioning frame 29 and the piston block 30 to slide upward along the limiting groove 26, while compressing the resistance spring 37. As the piston block 30 moves upward, the internal space of the limiting groove 26 is compressed, and the pressure increases, causing the edible glue in the groove to open the first one-way valve 34 and flow into the conveying channel 32 of the applicator roller 27 through the glue guiding channel 31. Finally, it seeps out from several discharge ports 33 to the surface of the applicator roller 27, realizing quantitative glue discharge. Because the stroke of the piston block 30 is limited by the slice resistance distance and the deformation range of the resistance spring 37, the amount of glue discharged each time is consistent, achieving the effect of automatic quantitative glue supply. At the same time, the second drive motor 38 on one side of the fixed frame 13 drives the transmission rod 14 to rotate, driving the hot press plate 12 to rotate synchronously. The applicator roller 27 generates friction due to contact with the slice surface. The friction causes the slice to rotate, evenly applying the exudated glue to the pressing surface of the slice. This effectively prevents the slice from springing back and breaking after being flattened. The glue penetrates the cut surface to form an elastic film, which can restrain fiber stress and reduce morphological changes caused by the release of internal stress. At the same time, it repairs micro-cracks and prevents crack expansion caused by contact force during testing. In addition, this structure is linked with the flattening mechanism, and the application is completed simultaneously during the flattening process without increasing the production cycle. This reduces waste caused by springback and breakage and eliminates the need for complicated post-processing procedures. While ensuring product quality stability, it improves production efficiency and reduces overall costs.

[0050] It should also be noted that when the flattening and shaping operations are completed, the electric telescopic rod 3 drives the hot press plate 12 to rise, the resistance force on the applicator roller 27 disappears, the resistance spring 37 resets and pushes the piston block 30 to move down. At this time, a negative pressure is formed inside the limiting groove 26, and the glue in the liquid storage tank 36 pushes open the second one-way valve 35 and flows into the limiting groove 26, completing the glue replenishment and preparing for the next shaping. Throughout the process, the first one-way valve 34 prevents the glue from flowing back into the limiting groove 26, and the second one-way valve 35 prevents the glue in the limiting groove 26 from flowing back into the liquid storage tank 36, ensuring the orderly supply and discharge of glue.

[0051] It should also be noted that the adhesive used in this device is a readily available edible adhesive, which does not affect the edible and medicinal effects of the slices. Its components are safe and biodegradable, and will not interfere with the retention and dissolution of the active ingredients. Furthermore, the quantitatively applied adhesive layer is uniform and thin, and will not interfere with the accuracy of thickness detection.

[0052] The present invention also provides an operating method for an automated thickness measurement device for processing sliced ​​Ligusticum chuanxiong, comprising the following steps:

[0053] S1: First, the slice of Ligusticum striatum that needs to be measured is placed on the placement platform 5 at the top of the thickness measuring platform 1 through the existing intermittent conveying mechanism. Then, the mounting frame 6 and the limiting cylinder 4 are lowered by controlling the electric telescopic rod 3. At this time, the flattening component at the bottom of the limiting cylinder 4 contacts the Ligusticum striatum slice to be tested and flattens the raised center or edge of the Ligusticum striatum slice to ensure the accuracy of subsequent testing.

[0054] S2: After the slice of Ligusticum chuanxiong to be tested is flattened by the flattening component, the shaping component is controlled to apply a small amount of edible glue to the flattening surface of the slice. The glue penetrates into the cut surface to form an elastic film, which can bind the fiber stress, reduce the shape change of the slice due to the release of internal stress, prevent it from resetting after flattening, and repair micro cracks to prevent crack expansion caused by contact force during the testing process.

[0055] S3: After the slice has been processed by the flattening component and the shaping component, the electric telescopic rod 3 is controlled to drive the mounting frame 6 and the limiting cylinder 4 to rise a certain distance. Then, the stepper motor 7 is controlled to drive the limiting cylinder 4 to rotate 180 degrees, so that the thickness measuring component at the top of the limiting cylinder 4 faces downward. Then, the electric telescopic rod 3 is controlled again to drive the mounting frame 6 and the limiting cylinder 4 to descend, so that the thickness measuring component contacts the slice of Ligusticum chuanxiong to be tested, thereby realizing multi-point slice thickness detection.

[0056] S4: After the test is completed, the electric telescopic rod 3 is controlled to lift the mounting frame 6 and the limiting cylinder 4 a certain distance. Then, the stepper motor 7 is controlled to rotate the limiting cylinder 4 180 degrees to complete the switching of the flattening component and the shaping component facing downward. Then, the tested slice is transported out through the existing intermittent conveying mechanism, and another slice of Ligusticum chuanxiong is placed on the top of the thickness measuring table 1 for intermittent cyclic thickness measurement.
