Description

Technical Field

[0001] The invention relates to the technical field of viscosity measurement, in particular to a device for measuring the viscosity of traditional Chinese medicine. Background Art

[0002] Viscosity is an important indicator for measuring the fluidity and stability of Chinese medicine preparations. It can reflect the composition, molecular structure, solubility, uniformity, aggregation and other characteristics of Chinese medicine preparations. Viscosity is one of the important parameters for quality control of Chinese medicine preparations. By testing the viscosity, we can understand the fluidity and stability of Chinese medicine preparations, so as to judge whether its quality meets the requirements, and can predict the absorption, distribution, metabolism and excretion of Chinese medicine preparations in the body, providing an important basis for the research and development and use of drugs. Testing the viscosity of Chinese medicine is an important means to ensure the quality of Chinese medicine preparations, guide production and predict performance. Through scientific and accurate viscosity testing, it can provide strong support for the research and development, production and application of Chinese medicine.

[0003] After searching, the Chinese patent with publication number CN203688401U discloses a Chinese medicine viscosity tester, which contains a bracket, a telescopic test device and a timer. The telescopic test device and the timer are fixedly connected to the bracket crossbeam. The telescopic test device contains a sleeve, and the sleeve contains a tension spring. One end of the tension spring is connected to the top of the telescopic test device, and the other end is connected to one end of the telescopic rod. The bottom of the telescopic rod is provided with a timer start timing contact, the middle and upper part of the sleeve is provided with a timer stop timing contact, and the upper half of the telescopic rod is provided with a limit protrusion, and the upper and lower surfaces of the limit protrusion are provided with conductive contacts. The technical structure is simple, the testing process is simple, and it can reduce the problem of operators wasting operating time due to unstable viscosity during the preparation of powder, thereby improving production efficiency.

[0004] When measuring traditional Chinese medicine, the above-mentioned viscosity meter may interfere with the timer in the viscosity meter due to the conductivity of the traditional Chinese medicine, affecting the accuracy of the timing. At the same time, due to the limited sample testing range, the time obtained by the timer is generally short within a short moving distance. Especially when dealing with samples with similar viscosity, the accuracy of the timer may not be able to effectively distinguish these subtle differences, thereby affecting the accuracy of the viscosity measurement. Secondly, the viscosity of different traditional Chinese medicines varies significantly, which places high demands on the telescopic device of the viscosity meter. If the design of the telescopic device cannot match the testing requirements of all traditional Chinese medicines, the timing may be too short to conduct a full analysis, or the device may be unable to move due to excessive viscosity. This will not only affect the accuracy of the measurement results, but may also cause damage to the equipment. In addition, the viscosity meter usually requires a large number of test samples, and the production process of traditional Chinese medicine products is complicated and costly. A large number of sample requirements can easily lead to waste of traditional Chinese medicine.

[0005] Therefore, it is necessary to design a Chinese medicine viscosity measuring device to solve the above problems. Summary of the invention

[0061] 1. By setting up the test rod and the counterweight platform, reading the distance the test rod moves under a constant force, and comparing it with the relationship table between distance and viscosity value, the viscosity value of the Chinese medicine can be quickly obtained. By replacing standard weights of different masses, it can adapt to the testing needs of Chinese medicine samples with different viscosities, so that the equipment can be widely used in the viscosity determination of various Chinese medicines, improving the practicability and universality of the equipment, thereby further improving the accuracy and stability of the test;

[0062] 2. By setting the function of the movable pulley, the pulling force of the standard weight on the test rod on the counterweight table is amplified, so that the system can measure Chinese medicines with higher viscosity, expanding the measurement range of the equipment. At the same time, the moving distance of the counterweight table is twice the upward moving distance of the test rod. By amplifying the moving distance, more accurate observation can be achieved. For Chinese medicines with similar viscosity, the difference between the test results is more obvious, which improves the distinguishability. Since the path of the far end of the pointer is greater than the distance of the counterweight table movement, the reading accuracy of the test is further improved. The test results can be displayed in real time and intuitively from the reading slot, which is convenient for the test personnel to observe and record;

[0063] 3. The test process is automated by setting the timer and the electromagnet to work together, ensuring the smoothness of the test process. The on and off of the electromagnet is precisely controlled by the timer, which enables the release and locking of the test rod, improves the system response speed, ensures the stability and accuracy of the test results, and ensures the consistency of the test conditions by precisely controlling the test time.

[0064] 4. By setting the operating rod, the extrusion component can squeeze out all the Chinese medicine in the holding tube, avoiding the waste of precious medicinal materials. The extruded Chinese medicine can be further diluted or added with drugs for preparation and testing, which improves the utilization rate of Chinese medicine resources. The extrusion component can slide out of the holding tube for easy cleaning and maintenance. The design of the flexible ring not only achieves a good extrusion effect, but also avoids damage to the equipment during the cleaning process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0076] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0077] Reference Figure 1-10A Chinese medicine viscosity measuring device comprises a base plate 1; a bracket 2, fixedly mounted on the base plate 1; a test rod 3, arranged on the bracket 2, and a test plate is fixedly mounted on the end of the test rod 3 away from the bracket 2; a base bracket 31, fixedly mounted on the base plate 1 at a position corresponding to the test rod 3, and a heating device is arranged in the base bracket 31; a receiving tube 32, arranged on the base bracket 31 and adapted to the test rod 3, and the opening of the receiving tube 32 is slightly larger than the size of the test plate; a mounting plate 33, fixedly mounted on the base plate 1; a timer 34, fixedly mounted on the mounting plate 33; a counterweight platform 5; a driving assembly, arranged between the test rod 3 and the counterweight platform 5; an indicating assembly, arranged on the mounting plate 33; an extrusion assembly, arranged in the receiving tube 32; a weight box 11 is fixedly mounted on the base plate 1, and a plurality of standard weights 111 of standard mass are arranged in the weight box 11.

[0078] The Chinese medicine to be tested for viscosity is placed in the accommodating tube 32, and the test rod 3 is extended into the accommodating tube 32 so that the test plate is in a preset initial position. At this time, no counterweight is added to the counterweight platform 5, and the test rod 3 can be stationary at the initial position under the action of its own weight, and a counterweight of standard mass is added to the counterweight platform 5. The preset test time is set by the timer 34. At the beginning of the timing, the test rod 3 moves upward from the Chinese medicine submerged in the test plate under the pulling force provided by the counterweight. When the timing ends, the distance moved by the test rod 3 under the viscosity of the Chinese medicine to be tested under a constant force within a certain period of time can be obtained. By comparing the relationship between the distance and the viscosity value, the viscosity of the Chinese medicine can be obtained, and for Chinese medicine samples with the same viscosity, the practicability and universality of the equipment can be improved by replacing standard weights 111 of different masses.

[0079] Reference Figure 1-4 The driving assembly includes: a movable pulley 4, which is arranged between the bracket 2 and the test rod 3 and is fixedly connected to the test rod 3; a fixed pulley 41, which is fixedly mounted on the side of the bracket 2 close to the bottom plate 1; a traction rope 42, one end of which is fixedly mounted on the bracket 2, and the other end passes around the movable pulley 4 and the fixed pulley 41 and is fixedly connected to the counterweight platform 5; an emergency stop assembly, which is arranged on the mounting plate 33; wherein a placement groove is provided on the counterweight platform 5; the indicating assembly includes: a rotating shaft 6, which is rotatably mounted on the end of the mounting plate 33 away from the counterweight platform 5; a pointer 61, which is fixedly mounted on the rotating shaft 6; a guide frame 62, which is fixedly mounted on one end of the rotating shaft 6 passing through the mounting plate 33 and is arranged in line with the pointer 61; a guide block 63, which is fixedly mounted on the side wall of the counterweight platform 5 and is adapted to the guide frame 62; a reading groove 64, which is arranged on the mounting plate 33 and is adapted to the pointer 61; the distance between the guide block 63 and the rotating shaft 6 is less than the length of the pointer 61, and a plurality of groups of indications are arranged on the reading groove 64.

[0080] When the test rod 3 moves upward, the movable pulley 4 causes the counterweight platform 5 to move twice the distance of the test rod 3 moving upward. By amplifying the moving distance, more convenient observation can be achieved, so that the test results of Chinese medicines with similar viscosity have better distinguishability. The downward movement of the counterweight platform 5 can drive the rotating shaft 6 to rotate, and at the same time drive the pointer 61 to rotate, so as to indicate the corresponding reading in the reading slot 64, which is convenient for the test personnel to directly record the test results in a timely and convenient manner after each experiment. By setting the distance between the guide block 63 and the rotating shaft 6 to be less than the length of the pointer 61, the path that the far end of the pointer 61 slides through is greater than the distance that the counterweight platform 5 moves, so that a smaller reading value can be set at the end of the pointer 61, and then by amplifying the moving distance of the counterweight platform 5, a test result with higher reading accuracy can be achieved, thereby improving the test interval of the equipment and the accuracy of the test.

[0081] Reference Figure 3 and Figure 4 The emergency stop assembly includes: a friction plate 7, which is fixedly mounted on one end of the rotating shaft 6 passing through the mounting plate 33; an electromagnet 71, which is fixedly mounted on the timer 34 and electrically connected to the timer 34, and a groove is provided on the electromagnet 71; a slider 72, which is slidably mounted in the groove; a spring 73, which is fixedly mounted between the slider 72 and the groove; a metal plate 74, which is fixedly sleeved on the slider 72; a friction plate 75, which is fixedly mounted on one end of the slider 72 away from the electromagnet 71, and the friction plate 75 is adapted to the friction plate 7.

[0082] When the timer 34 is working, the electromagnet 71 is driven to work at the same time. At this time, the electromagnet 71 attracts the metal plate 74, drives the slider 72 and the friction plate 75 to slide into the groove to compress the spring 73, thereby separating the friction plate 75 from the friction plate 7, and the rotating shaft 6 can rotate. When the timer 34 ends, the electromagnet 71 is de-energized. At this time, the slider 72 drives the friction plate 75 to contact the friction plate 7 under the action of the spring 73, so that the rotating shaft 6 stops moving quickly. At this time, the number pointed to by the pointer 61 is the viscosity value corresponding to the distance moved by the test rod 3 within the standard time. The test rod 3 is released and locked by the automatic control system of the timer 34, so that the system response speed is improved, the accuracy of the recorded number is ensured, and the stability and accuracy of the test results are ensured.

[0083] Reference Figure 6-9The extrusion assembly includes: a mounting frame 9, which is slidably mounted in the accommodating tube 32; a slide groove 91, which is provided on the mounting frame 9 and is arranged in a "M" shape; eight slide rods 92, which are respectively slidably mounted in the slide grooves 91; eight inclined blocks 93, which are respectively fixedly mounted on the ends of the slide rods 92 away from the outer wall of the mounting frame 9; a flexible ring 94, which is fixedly sleeved on the ends of the slide rods 92 away from the inclined blocks 93; a limiting plate 97, which is fixedly mounted on the ends of the mounting frame 9 away from the flexible ring 94, and a limiting ring is arranged at the center of the limiting plate 97; a ball 95, which is arranged between the inclined block 93 and the limiting ring and is adapted to the inclined block 93; a threaded sleeve 96, which is slidably mounted in the limiting ring and one end of which is fixedly connected to the ball 95, accommodating A through hole compatible with the threaded sleeve 96 is provided at the bottom of the tube 32; an elastic ring 98 is fixedly mounted on the eight inclined blocks 93; a fixing plate 99 is fixedly installed at the end of the mounting frame 9 away from the limiting plate 97; an operating component is arranged on the accommodating tube 32; the operating component includes: a storage groove 101, which is provided on the bottom wall of the accommodating tube 32; an operating rod 10, which is slidably installed in the storage groove 101, and the end of the operating rod 10 away from the bottom of the storage groove 101 is provided with a thread compatible with the threaded sleeve 96; a positioning hole 102 is provided on the base 31, and is compatible with the operating rod 10; wherein the length of the operating rod 10 is equal to the sum of the length of the storage groove 101 and the depth of the positioning hole 102.

[0084] After the test is completed, the accommodating tube 32 can be removed, and the accommodating tube 32 can be inverted and aligned with the container for containing Chinese medicine, the operating rod 10 can be taken out from the storage groove 101, and the thread at the end of the operating rod 10 can be inserted into the through hole and combined with the threaded sleeve 96, and the operating rod 10 can be pushed downward. The operating rod 10 can drive the fixed plate 99 to squeeze the Chinese medicine downward along the accommodating tube 32. At the same time, when the operating rod 10 is pressed downward, the threaded sleeve 96 and the ball 95 can be driven to slide downward and squeeze the eight inclined blocks 93 at the same time, and then the sliding rod 92 can be pushed outward along the sliding groove 91, so that the flexible ring 94 fixed on the eight sliding rods 92 can be stretched and stretched, and fit tightly against the inner wall of the accommodating tube 32. When squeezing out the Chinese medicine downward, the part hanging on the wall can be squeezed out together, and the operating rod 10 can be pulled back to make the threaded sleeve 96 and the ball 95 slide upward and release the inclined block 93 at the same time. Under the action of the elastic ring 98, the sliding rod 92 retracts inward, driving the flexible ring 94 to retract between the fixed plate 99 and the mounting frame 9, and the flexible ring 94 is separated from the inner wall of the receiving tube 32, and the Chinese medicine hanging on the wall will not be scraped. After repeatedly pulling and pulling the operating rod 10 several times, the Chinese medicine in the receiving tube 32 can be basically squeezed out, so that it can be further diluted or added with medicine for preparation and testing, or recycled to avoid waste, which can achieve a better extrusion effect while being easy to clean and convenient to use.

[0085] Reference Fig.10Two fixed frames 8 are symmetrically fixedly installed on the bracket 2, guide rods 82 compatible with the fixed frames 8 are symmetrically fixedly installed on the movable pulley 4, and a buffer pad 81 compatible with the test board is fixedly installed at the bottom of the fixed frame 8, and the bottom surface of the fixed frame 8 is slightly higher than the top surface of the accommodating tube 32; the fixed frame 8 and the guide rod 82 can ensure that the movable pulley 4 and the test rod 3 maintain vertical movement, avoiding errors in the test results caused by shaking during the pulling process, and by setting the bottom surface of the fixed frame 8 to be slightly higher than the top surface of the accommodating tube 32 and the buffer pad 81, it can play a role of limiting protection when the test board rises, thereby improving the safety of equipment use, increasing the service life of the equipment, and saving costs.

[0086] The specific working principle of the present invention is as follows:

[0087] The Chinese medicine that needs to measure the viscosity is placed in the accommodating tube 32, the timer 34 is turned on, the heating time is set, and the Chinese medicine is subjected to a bubble exhaust process to ensure the accuracy of the measurement result. After exhausting for a period of time, the test rod 3 is extended into the accommodating tube 32 so that the test plate is in a preset initial position. At this time, no counterweight is added to the counterweight platform 5, and the test rod 3 can be stationary in the initial position under the action of its own weight. After the timing of the timing machine ends, that is, the exhaust is completed, the drive assembly is fixed and cannot be moved, and a counterweight of standard mass is added to the counterweight platform 5. The preset test time is set by the timer 34, and the drive assembly is released at the beginning of the timing. The test rod 3 moves upward from the Chinese medicine of the submerged test plate under the pulling force provided by the counterweight. When the timing ends, the drive assembly is fixed again, and the distance that the test rod 3 moves under the viscosity of the Chinese medicine to be tested under a constant force within a certain period of time can be obtained. After reading the value of the indicating component, by comparing the distance with the viscosity value comparison table, the viscosity of the Chinese medicine can be obtained, and based on this, the effect of the preparation of the Chinese medicine can be judged or summarized. For Chinese medicine samples with the same viscosity, the counterweight that can make the test rod 3 move a larger distance without moving out of the accommodating tube 32 can be found by replacing standard weights 111 of different masses, and the corresponding force value can be referred to the matching comparison table, thereby improving the practicality and universality of the equipment.

[0088] When the test rod 3 moves upward, through the action of the movable pulley 4, the pulling force of the corresponding standard weight 111 on the counterweight platform 5 on the test rod 3 can be amplified, and at the same time, the distance moved by the counterweight platform 5 can be twice the distance of the test rod 3 moving upward. Not only can the system measure Chinese medicines with greater viscosity, but also more convenient observation can be achieved by amplifying the moving distance, so that the test results of Chinese medicines with similar viscosities have better distinguishability, which can improve the test interval and test accuracy of the equipment. And the downward movement of the counterweight platform 5 can drive the guide block 63 to move downward. When the guide block 63 moves downward, it will slide in the guide frame 62 and turn the shaft 6 to rotate. When the shaft 6 rotates, it drives the pointer 61 to rotate, so as to indicate the corresponding reading in the reading slot 64. The corresponding data in the comparison table can be directly set in the reading slot 64, and the corresponding comparison table parameters under different counterweights can be set in parallel in the reading slot 64, so that the test personnel can directly record the test results in a timely and convenient manner after each experiment. By setting the distance between the guide block 63 and the rotating shaft 6 to be smaller than the length of the pointer 61, the path along which the far end of the pointer 61 slides can be made greater than the distance along which the counterweight platform 5 moves, so that a smaller reading value can be set at the end of the pointer 61, thereby achieving a test result with higher reading accuracy by enlarging the moving distance of the counterweight platform 5.

[0089] When heating and exhausting and the test begins, the timer 34 works and drives the electromagnet 71 to work at the same time. At this time, the electromagnet 71 attracts the metal plate 74, drives the slider 72 and the friction plate 75 to slide into the groove to compress the spring 73, so that the friction plate 75 is separated from the friction plate 7. While the rotating shaft 6 can rotate, the counterweight platform 5 connected to the guide frame 62 through the guide block 63 can move up and down. At this time, the standard weight 111 of the counterweight is removed, and the test rod 3 can be immersed in the Chinese medicine to be tested under its own weight. Correspondingly, when the exhaust and the test are finished, the timer 34 ends the timing, and the electromagnet 71 stops being energized. At this time, the slider 72 drives the friction plate 75 to contact the friction plate 7 under the action of the spring 73, so that the rotating shaft 6 stops moving quickly, and then the system stops moving. When the exhaust is finished, the counterweight platform 5 is locked, and after the standard weight 111 of the counterweight is added, the test rod 3 can continue to remain in the initial position to facilitate subsequent tests. After the test is finished, the counterweight platform 5 is quickly locked while moving downward, and the indication pointed to by the pointer 61 is the viscosity value corresponding to the distance moved by the test rod 3 within the standard time. By controlling the on and off of the electromagnet 71 through the timer 34, it can not only ensure the smooth progress of the test process and operation, but also release and lock the test rod 3 through the automatic control system of the timer 34, improve the system response speed, ensure the accuracy of the recorded indication, and further ensure the stability and accuracy of the test results. The working principle and connection method of the timer 34 and the electromagnet 71 are existing mature technologies, which will not be elaborated here.

[0090] When the measured viscosity value is different from the expected value, or when the medicinal materials are precious and difficult to prepare, the accommodating tube 32 can be removed after the test, and the accommodating tube 32 can be inverted and aligned with the container containing the Chinese medicine to make the Chinese medicine flow out. For Chinese medicine with high viscosity and easy to hang on the wall, the operating rod 10 can be taken out from the storage tank 101, and the thread at the end of the operating rod 10 is inserted into the through hole and combined with the threaded sleeve 96, and the operating rod 10 is pushed downward, and the operating rod 10 can drive the mounting frame 9 and the fixing plate 99 to squeeze the Chinese medicine downward along the accommodating tube 32. At the same time, when the operating rod 10 is pressed down, the threaded sleeve 96 and the ball 95 can be driven to slide downward and squeeze the eight inclined blocks 93, and then the slide bar 92 is pushed outward along the slide groove 91, so that the flexible ring 94 fixed on the eight slide bars 92 is stretched and stretched, and is tightly fitted with the inner wall of the accommodating tube 32, and the wall-hanging part can be squeezed downward together when the Chinese medicine is squeezed downward. When moving to the opening of the accommodating tube 32, the operating rod 10 can be pulled back, so that the threaded sleeve 96 and the ball 95 slide upward and release the inclined block 93 at the same time. Under the action of the elastic ring 98, the sliding rod 92 retracts inward, driving the flexible ring 94 to retract between the fixed plate 99 and the mounting frame 9. At this time, the fixed plate 99 and the mounting frame 9 are pulled back to the bottom of the accommodating tube 32. The flexible ring 94 is separated from the inner side wall of the accommodating tube 32 and will not scrape the Chinese medicine hanging on the wall. After repeatedly pulling the operating rod 10 several times, the Chinese medicine in the accommodating tube 32 can be basically squeezed out, so that it can be further diluted or added to the drug preparation test, or recycled to avoid waste. And the extrusion assembly can slide out of the accommodating tube 32, which can achieve a good extrusion effect while being easy to clean and convenient to use. The part of the operating rod 10 extending out of the storage tank 101 is convenient for taking out the operating rod 10, and can cooperate with the positioning hole 102 to achieve the positioning effect when the accommodating tube 32 is installed on the bottom support 31.

[0091] The fixed frame 8 and the guide rod 82 can ensure that the movable pulley 4 and the test rod 3 maintain vertical movement, avoiding errors in the test results caused by shaking during the lifting process, and by setting the bottom surface of the fixed frame 8 slightly higher than the top surface of the accommodating tube 32 and the buffer pad 81, it can play a role in limiting protection when the test plate rises. On the one hand, it can remind the standard weight 111 that it is too heavy and can be replaced with a light weight appropriately. On the other hand, it can protect the counterweight platform 5 and the standard weight 111 from falling to the bottom plate 1 and causing damage to the weight and equipment, thereby improving the safety of equipment use, increasing the service life of the equipment, and saving costs.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
