Description

Technical Field

[0001] The present invention belongs to the technical field of traditional Chinese medicine inspection, and particularly relates to a sample extraction device for detecting components of traditional Chinese medicine. Background Art

[0002] Before mass production in a factory, small-batch preparation is often adopted to verify the feasibility, stability, and repeatability of the production process. At the same time, small-batch production can also detect various data of the produced traditional Chinese medicine liquid, so as to determine parameters such as the production process.

[0003] When detecting the components of traditional Chinese medicine, the traditional Chinese medicine is often crushed into particles, and then the particles are stirred in a solvent to generate a uniform medicinal liquid during the boiling process. However, for special medicinal materials such as whole-herb traditional Chinese medicine, using the crushing method for boiling will cause loss of active ingredients. However, directly putting the traditional Chinese medicine into the boiling container will cause insufficient release of the active ingredients in the traditional Chinese medicine, resulting in the need for a long boiling time to minimize the waste of active ingredients. However, this will also lead to an increase in the overall processing time and a reduction in the preparation efficiency. Summary of the Invention

A central column is fixedly connected to the center of the inner bottom surface of the housing. A traditional Chinese medicine groove is provided on the top surface of the central column. A plurality of groups of extrusion openings are provided on the outer side surface of the central column. The extrusion openings communicate with the traditional Chinese medicine groove. One end of the sliding column facing the central column is fixedly connected with an extrusion head.

[0006] Preferably, the extrusion head is made of an elastic material. When the extrusion head is completely pushed forward, it abuts against the inner side surface of the traditional Chinese medicine groove, and there is a gap between adjacent two extrusion heads.

[0013] The beneficial effects of the present invention are as follows:

[0014] 1. In the present invention, in order to solve the problem of loss of active ingredients after the whole herb traditional Chinese medicine is pulverized, the medicinal properties in this type of traditional Chinese medicine are released from the medicinal materials by using an extrusion method, so as to effectively release the active ingredients in the traditional Chinese medicine while reducing the boiling time; when preparing a test sample by boiling traditional Chinese medicine, first load the above-mentioned type of medicinal materials into a gauze bag, and then load it into the traditional Chinese medicine tank. With the start of the motor, the rotating shaft is driven to rotate through gear transmission, and then the disc on the rotating shaft is driven to rotate. At this time, under the drive of the groove, the sliding seat performs a linear reciprocating motion, and then drives the extrusion head at the front end of the sliding column to extrude the medicinal materials in the traditional Chinese medicine tank. With the repeated extrusion of the extrusion head, the fibers in the medicinal materials are separated, so as to release the active ingredients from the medicinal materials as much as possible without pulverizing the medicinal materials. At the same time, with the reciprocating movement of the extrusion head, when the extrusion head moves forward to extrude the medicinal materials in the traditional Chinese medicine tank, the solution in the traditional Chinese medicine tank is also pushed by the extrusion head and then overflows from the top of the traditional Chinese medicine tank to the central column. And as the extrusion head returns, the liquid at the top of the central column flows into the traditional Chinese medicine tank, thus forming an impact on the gauze bag in the traditional Chinese medicine tank, so as to change the shape of the gauze bag and prevent the subsequent extrusion effect of the extrusion head from decreasing after the shape of the squeezed gauze bag is fixed.

[0015] 2. Secondly, as the motor rotates, the motor drives the spiral auger to rotate through a coaxial speed reducer. As the spiral auger rotates, the solution in the open cavity containing the spiral auger is transported upward. At this time, the solution near the central column will move from the inner water channel into the open cavity. Through the lifting of the spiral auger, the reciprocating movement of the extrusion head, and the rotation of the disc, the solution in the outer shell will flow in all directions at this time, so that the active ingredients are more evenly distributed in the solution, avoiding the problem of too high or too low data during detection.

[0016] 3. Finally, by placing the whole herb traditional Chinese medicine in a gauze bag and then squeezing the gauze bag and the traditional Chinese medicine inside by the extrusion head to release the medicinal properties of the traditional Chinese medicine, the problem of filtering the finished medicinal liquid in the traditional method of decocting the traditional Chinese medicine after pulverizing it is avoided, so that there are no medicinal particles in the decocted traditional Chinese medicine liquid, ensuring the purity of the traditional Chinese medicine liquid.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 to 5 shown, an embodiment of the present invention provides a sample extraction device for detecting traditional Chinese medicine components, including a housing 1 and a base 2. The housing 1 is fixedly connected to the base 2. A plurality of centrally symmetric rotating shafts 5 are rotatably installed inside the housing 1. A plurality of equally spaced discs 6 are fixedly sleeved on the rotating shafts 5. Grooves 7 are formed in the discs 6. A plurality of groups of brackets 8 are fixedly connected to the inner bottom surface of the housing 1. A plurality of equally spaced guide frames 9 are fixedly connected inside the brackets 8. One end of the guide frame 9 is slidably sleeved with a sliding column 10. One end of the sliding column 10 facing the disc 6 is fixedly connected with a sliding seat 11. Pushing columns 13 are fixed on both the upper and lower surfaces of the sliding seat 11. The pushing column 13 on the bottom surface of the sliding seat 11 is slidably connected in the groove 7. A central column 16 is fixedly connected to the center of the inner bottom surface of the housing 1. A traditional Chinese medicine groove 17 is formed on the top surface of the central column 16. A plurality of groups of extrusion openings 18 are formed on the outer side surface of the central column 16. The extrusion openings 18 communicate with the traditional Chinese medicine groove 17. An extrusion head 15 is fixedly connected to one end of the sliding column 10 facing the central column 16.

[0025] In the present invention, in order to solve the problem of loss of active ingredients after the whole herb traditional Chinese medicine is crushed, the medicinal properties in this type of traditional Chinese medicine are released from the medicinal materials by using an extrusion method, so as to effectively release the active ingredients in the traditional Chinese medicine while reducing the boiling time; when preparing a test sample by boiling traditional Chinese medicine, first, the above-mentioned type of medicinal materials are put into a gauze bag, and then the gauze bag is put into the traditional Chinese medicine groove 17. With the start of the motor 21, the rotating shaft 5 is driven to rotate through gear transmission, and then the disc 6 on the rotating shaft 5 is driven to rotate. At this time, under the drive of the groove 7, the sliding seat 11 performs a linear reciprocating motion, and then drives the extrusion head 15 at the front end of the sliding column 10 to extrude the medicinal materials in the traditional Chinese medicine groove 17. With the repeated extrusion of the extrusion head 15, the fibers in the medicinal materials are separated, so as to release the active ingredients from the medicinal materials as much as possible without crushing the medicinal materials. At the same time, with the reciprocating movement of the extrusion head 15, when the extrusion head 15 moves forward to extrude the medicinal materials in the traditional Chinese medicine groove 17, the solution in the traditional Chinese medicine groove 17 is also pushed by the extrusion head 15, and then overflows from the top of the traditional Chinese medicine groove 17 to the central column 16. As the extrusion head 15 returns, the liquid on the top of the central column 16 flows into the traditional Chinese medicine groove 17, thereby forming an impact on the gauze bag in the traditional Chinese medicine groove 17, so as to change the shape of the gauze bag and prevent the subsequent extrusion effect of the extrusion head 15 from decreasing after the shape of the squeezed gauze bag is fixed.

[0026] Secondly, as the motor 21 rotates, the motor 21 drives the spiral auger 19 to rotate through the coaxial speed reducer 23. As the spiral auger 19 rotates, the solution in the open cavity containing the spiral auger 19 is transported upward. At this time, the solution near the central column 16 will move from the inner water channel 20 into the open cavity. Through the lifting of the spiral auger 19, the reciprocating movement of the extrusion head 15, and the rotation of the disc 6, the solution in the housing 1 will flow in all directions at this time, so that the active ingredients are more evenly distributed in the solution, avoiding the problem of too high or too low data during detection.

[0027] Finally, by placing the whole herb Chinese medicinal materials in a gauze bag and then squeezing the gauze bag and the Chinese medicinal materials inside through the extrusion head 15 to release the medicinal properties of the Chinese medicinal materials, the problem of filtering the finished medicinal liquid in the traditional method of decocting Chinese medicinal materials after pulverizing them is avoided, so that there are no medicinal material particles in the decocted Chinese medicinal liquid, ensuring the purity of the Chinese medicinal liquid.

[0028] Among them, the extrusion head 15 is made of an elastic material. When the extrusion head 15 is completely pushed forward, it abuts against the inner side surface of the medicine trough 17, and there is a gap between two adjacent extrusion heads 15.

[0029] The gap between the two extrusion heads 15 allows the Chinese medicinal materials to still have a certain moving space when being squeezed, thus avoiding the fibers of the Chinese medicinal materials being compacted due to excessive squeezing, resulting in the solution being unable to effectively release the active ingredients in the Chinese medicinal materials.

[0030] Among them, a through straight sliding groove 12 is opened on the top surface of the guide frame 9, and the pushing column 13 on the top surface of the sliding seat 11 is slidably connected in the straight sliding groove 12.

[0031] The straight sliding groove 12 opened on the guide frame 9 enables the sliding seat 11 to move along a specified direction during the sliding process, avoiding the sliding seat 11 from undergoing displacement in other directions (such as tilting), and being unable to effectively drive the extrusion head 15 to squeeze the medicinal materials in the medicine trough 17.

[0032] Among them, an open cavity is opened on the top surface of the central column 16. The bottom of the central column 16 is fixedly connected with a coaxial speed reducer 23, and the output end of the coaxial speed reducer 23 is fixedly connected with a spiral auger 19, and the spiral auger 19 is located at the center of the central column 16.

[0033] Through the provided coaxial speed reducer 23, the motor 21 drives the spiral auger 19 to rotate at a certain speed, thereby lifting the solution at the bottom inside the housing 1 upward. On the one hand, it prevents the active ingredients in the medicinal materials from depositing at the bottom of the housing 1; on the other hand, the decelerated spiral auger 19 also avoids the solution being impacted on the top cover 3 after being lifted at a high speed, causing the active ingredients to adhere to the top cover 3 and resulting in the loss of active ingredients.

[0034] Among them, a plurality of centrally symmetric inner water channels 20 are provided inside the central column 16. One end of the inner water channel 20 is opened on the outer side surface of the central column 16, and the other end of the inner water channel 20 is opened on the bottom surface of the open cavity inside the central column 16. A first spring 14 is elastically connected between the guide frame 9 and the sliding seat 11, and the first spring 14 is movably sleeved on the sliding column 10.

[0035] Through the provided inner water channels 20, the solution inside the outer shell 1 is lifted upward as the spiral auger 19 rotates, so that the solution inside the outer shell 1 is in a circulating flow state, ensuring that the active ingredients are evenly distributed in the solution.

[0036] Among them, a motor 21 is fixedly connected inside the base 2. The output shaft of the motor 21 is fixedly sleeved with a first gear 22. A plurality of centrally symmetric second gears 24 are rotatably installed on the outer bottom surface of the outer shell 1. The rotating shaft 5 extends out of the bottom end of the outer shell 1 and is fixedly sleeved with a third gear 25. The first gear 22 meshes with the second gear 24, and the third gear 25 meshes with the second gear 24. The output shaft of the motor 21 is fixedly connected to the input end of the coaxial speed reducer 23. The top end of the outer shell 1 is fixedly connected with a top cover 3. A feeding port 4 is opened in the center of the top cover 3, and a feeding cover is clamped in the feeding port 4.

[0037] Working principle:

[0038] When using this device to extract the active ingredients in traditional Chinese medicine for detection, first place the whole herb traditional Chinese medicine in a bag such as a gauze bag, then put the gauze bag into the traditional Chinese medicine tank 17, and fix the top end of the gauze bag to the top end of the central column 16 to prevent the gauze bag from sinking to the bottom of the traditional Chinese medicine tank 17 after repeated extrusion.

[0039] After that, start the motor 21, so that the first gear 22 drives the third gear 25 to rotate through the transmission of the second gear 24, and then drives the rotating shaft 5 to rotate. As the rotating shaft 5 rotates, the disc 6 on the rotating shaft 5 starts to rotate, so that the disc 6 drives the sliding column 10 to reciprocate horizontally through the groove 7, and then the sliding column 10 drives the extrusion head 15 to extrude the traditional Chinese medicine in the traditional Chinese medicine tank 17.

[0040] By setting grooves 7 with different shapes, multiple extrusion heads 15 can be in different positions at the same time, so that the extrusion heads 15 can extrude the traditional Chinese medicine in the traditional Chinese medicine tank 17 at different frequencies.

[0041] As the motor 21 operates, the screw auger 19 connected to the motor 21 through the coaxial speed reducer 23 also rotates, thereby lifting the solution in the open cavity inside the central column 16 upward. As the solution in the central column 16 leaves, the solution inside the outer shell 1 flows along the inner water channel 20 into the interior of the central column 16. At the same time, under the rotation of the rotating shaft 5 and the disc 6, the solution inside the outer shell 1 flows in different directions, so that the squeezed active ingredients are evenly diffused in the solution, ensuring the accuracy of the sample test results.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
