Description

Technical Field

[0001] The invention relates to the technical field of drug liquid storage, in particular to a vitamin drug liquid storage tank used for the production of vitamin soft capsules. Background Art

[0002] In the production process of vitamin capsules, there are different types of vitamin capsules for different causes of disease. Vitamins are usually composed of a capsule shell and the contents (medicine solution) inside the capsule. The capsule shell is used to encapsulate the outer shell of the vitamin. The common type is gelatin capsule, and the capsule contents are usually vitamins, minerals, plant extracts or other nutrients. The main component of the capsule contents is vitamins. Some vitamins include vitamin A, B, C, D, E, etc., which can be used to select different vitamins to supplement the body. In the production process of vitamin soft capsules, because vitamins are easily oxidized, when storing vitamin medicine solutions, the storage tanks are usually vacuum-treated to prevent the vitamins from oxidizing with oxygen in the air and affecting subsequent production. In order to prevent the medicine solution from being stored for a long time and causing deposition and agglomeration, the medicine solution inside the storage tank needs to be stirred at all times. The vacuum setting can effectively reduce bubbles when stirring the vitamin medicine solution and improve production quality.

[0003] When storing liquid medicine in a closed storage tank, although it can effectively prevent the liquid medicine from coming into contact with oxygen and causing oxidation, as well as the generation of bubbles during the stirring process, the following problems still exist: when the storage tank is storing liquid medicine, the staff needs to regularly perform sample tests on the liquid medicine inside the storage tank to determine whether the liquid medicine inside meets the production level. However, the interior of the storage tank is in a vacuum state, and traditional sampling will destroy the vacuum environment inside the storage tank, causing external oxygen to enter the storage tank, and thus each time a sample is taken, the storage tank needs to be vacuumed again. The operation is relatively complicated and is not conducive to the subsequent storage of the storage tank. Therefore, a liquid medicine storage tank is designed to ensure that when sampling the liquid medicine inside the storage tank, the interior is always in a vacuum state to ensure the storage quality of the liquid medicine in the storage tank. Summary of the invention

[0004] In view of the problem in the prior art that when sampling the liquid medicine inside the storage tank, the vacuum environment inside the storage tank will be destroyed, thereby affecting the subsequent storage of the storage tank, a vitamin liquid medicine storage tank for the production of vitamin soft capsules is proposed.

[0005] The present application provides a vitamin liquid storage tank for the production of vitamin soft capsules, the purpose of which is: by setting a storage component, when the storage tank is vacuum storing the liquid medicine, the stirring element inside it can continuously and slowly stir the internal liquid medicine to prevent sedimentation and uneven liquid medicine from occurring, and by the mutual cooperation of the sampling component and the control component, the storage tank can be kept in a closed state at all times during the sampling process to prevent external oxygen from entering the storage tank and causing oxidation of the liquid medicine, and at the same time, the pressure inside the storage tank can be kept in a normal state to ensure the storage environment of the liquid medicine.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] Example 1, reference Figure 1-Figure 6 , which is the first embodiment of the present invention, provides a vitamin liquid storage tank for the production of vitamin soft capsules, comprising a plurality of legs 1, and a storage unit fixedly mounted on the legs 1, wherein the storage unit comprises a storage component and a sampling component mounted on the plurality of legs 1;

[0033] The storage component includes a mounting plate 2 fixedly mounted between a plurality of legs 1, a support ring 3 fixedly mounted on the mounting plate 2, an inner tank 4 fixedly mounted on the support ring 3, an outer tank 5 fixedly mounted on the outer ring of the support ring 3, a top cover 6 fixedly mounted on the outer tank 5, a liquid discharge port 7 fixedly mounted on the top cover 6, a liquid level gauge 8 and a pressure gauge 9 fixedly mounted on the top cover 6, an air extraction pipe 10 fixedly mounted on the top cover 6, a limit rod 11 fixedly mounted on both sides of the inner wall of the inner tank 4, a chassis 12 slidably mounted on the inner wall of the inner tank 4, a servo motor 13 fixedly mounted on the lower end of the mounting plate 2, a drive rod 14 fixedly mounted on the drive end of the servo motor 13, a threaded rod 15 fixedly mounted on the drive rod 14, and a control component is mounted on the threaded rod 15;

[0034] Limiting grooves 16 are provided on both sides of the chassis 12. The chassis 12 is slidably installed on the inner wall of the inner tank 4 by cooperating with the corresponding limiting rods 11 through the two limiting grooves 16. Discharge ports for discharging materials are provided on the side walls of the inner tank 4 and the outer tank 5. The driving rod 14 slides through the lower end of the inner tank 4, and its upper end is located inside the inner tank 4. A sealing ring is installed between the driving rod 14 and the inner tank 4 to increase the sealing performance.

[0035] Reference Figure 3 and Figure 6 as well as Fig. 9 The control assembly includes a turntable 17 threadedly mounted on the threaded rod 15, a circular groove provided on the chassis 12, a one-way bearing 18 fixedly mounted in the circular groove, an inner ring of the one-way bearing 18 fixedly connected to the turntable 17, and a stirring element mounted on the turntable 17. The stirring element includes a plurality of connecting plates 19 fixedly mounted on the side wall of the turntable 17, two deflection rods 20 respectively fixedly mounted on the plurality of connecting plates 19, and a stirring rod 21 fixedly mounted between the two corresponding deflection rods 20.

[0036] Specifically, the storage component is used to seal and store the soft capsule liquid, the liquid level meter 8 is used to detect the liquid level of the liquid in the inner tank 4 in real time, so that the staff can judge the capacity of the liquid in the inner tank 4, the pressure gauge 9 is used to detect the pressure inside the inner tank 4, and the exhaust pipe 10 is used to extract the air in the inner tank 4 so that the interior of the inner tank 4 is in a vacuum state. One end of the exhaust pipe 10 is connected to an exhaust pump (not shown in the figure), and the exhaust pump is used to extract the air in the inner tank 4 so that the interior of the inner tank 4 is in a vacuum state. The vacuum state can better store the air in the inner tank 4, prevent the vitamins in the liquid medicine from reacting with the oxygen in the air to produce an oxidation reaction, and affect the storage of the internal liquid medicine in the inner tank 4. At the same time, the vacuum state can effectively reduce the gas in the liquid medicine, so that when the liquid medicine is stirred, the generation of bubbles can be effectively reduced, thereby improving the storage efficiency of the liquid medicine in the inner tank 4.

[0037] The stirring element is used to slowly stir the liquid medicine in the inner tank 4 to prevent the liquid medicine from being deposited and agglomerated due to long-term storage of the liquid medicine in the inner tank 4. This will cause the liquid medicine content in the inner tank 4 to be uneven, affecting the subsequent production quality. At the same time, slow stirring can further reduce the generation of bubbles and further improve the subsequent production quality. The control component is used to achieve different working effects by controlling the reverse rotation of the servo motor 13. By setting a one-way bearing 18 (the working principle of the one-way bearing 18 is that when the inner ring of the one-way bearing 18 rotates forward, the one-way bearing 18 is in a non-self-locking state. At this time, the outer ring of the one-way bearing 18 will not rotate when the inner ring of the one-way bearing 18 rotates forward. When the one-way bearing 18 rotates reversely, the one-way bearing 18 rotates reversely and is in a self-locking state. At this time, the rotation of the inner ring of the one-way bearing 18 will drive its outer ring to rotate synchronously. This is the prior art and will not be elaborated on here). When the servo motor 13 rotates forward, the driving end of the servo motor 13 drives the turntable 17 to rotate forward. At this time, the inner ring of the one-way bearing 18 fixedly connected to the turntable 17 rotates synchronously. Because the inner ring of the one-way bearing 18 rotates forward, it will not drive its outer ring to rotate. Therefore, when the servo motor 13 rotates forward, it only drives the turntable 17 to rotate. When the turntable 17 rotates slowly, it can slowly and evenly stir the liquid in the inner tank 4.

[0038] During use, the staff passes the produced soft capsule liquid into the inner tank 4 through the liquid discharge port 7, and closes the liquid discharge port 7, and extracts the air in the inner tank 4 through the vacuum pump, so that the inner tank 4 is in a vacuum state, and turns on the servo motor 13, so that the driving end of the servo motor 13 rotates slowly in the positive direction, and then drives the upper end of the turntable 17 to rotate slowly and synchronously through the driving rod 14 and the threaded rod 15, and the stirring rod 21 on the turntable 17 rotates synchronously to slowly stir the liquid medicine in the inner tank 4, so as to prevent the liquid medicine from being deposited and agglomerated due to long-term storage, and avoid uneven distribution of the liquid medicine.

[0039] Example 2, reference Figure 5-Figure 8, which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that the sampling component includes a sampling box 22 fixedly mounted on the side wall of the inner tank 4, a fixed plate 23 fixedly mounted on one end of the sampling box 22, a rotating nut 24 rotatably mounted on the fixed plate 23, a control rod 25 threadedly mounted in the rotating nut 24, and a movable plate 26 fixedly mounted at one end of the control rod 25, the movable plate 26 slides in the sampling box 22, and the shape and size of the end surface of the movable plate 26 is equal to the shape and size of the end surface of the inner wall of the sampling box 22, a vent hole is opened on the fixed plate 23, a driving assembly is installed on the sampling box 22, and a sample assembly is installed at the lower end of the sampling box 22. The driving assembly includes a control motor 27 fixedly mounted on the upper end of the sampling box 22, a driving gear 28 fixedly mounted on the driving end of the control motor 27, and a driven gear 29 fixedly mounted on the side wall of the rotating nut 24, and the lower end of the driving gear 28 is meshed with the upper end of the driven gear 29. The area ratio of the movable plate 26 to the chassis 12 is 10:1. The servo motor 13 is electrically connected to the control motor 27 , and the rotation ratio between the driving end of the servo motor 13 and the driving end of the control motor 27 is 1:10.

[0040] Specifically, the sampling component is used to ensure that the inner tank 4 is always in a closed state when the staff samples and tests the liquid medicine in the inner tank 4 during the storage of the liquid medicine, so as to prevent the staff from destroying the vacuum environment in the inner tank 4 during the sampling process and affecting the subsequent storage. In the initial state, the movable plate 26 is located at the innermost end of the sampling box 22, and the movable plate 26 is in contact with the inner wall of the inner tank 4, so that when the staff needs to take samples, by reversing the servo motor 13, the driving end of the servo motor 13 drives the turntable 17 to rotate in the opposite direction, and then the inner ring of the one-way bearing 18 rotates in the opposite direction. When the one-way bearing 18 rotates in the opposite direction, the inner ring drives the outer ring to rotate, so that when the turntable 17 rotates, it can drive the chassis 12 to rotate in the opposite direction. Because the limit rod 11 limits the chassis 12, the chassis 12 cannot rotate, and then the turntable 17 cannot rotate. A torsional force is generated between the turntable 17 and the threaded rod 15, so that the turntable 17 drives the chassis 12 to move slowly upward along the vertical direction of the threaded rod 15.

[0041] It should be emphasized that the threads on the threaded rod 15 and the control rod 25 are exactly the same. At the same time, because the area ratio of the movable plate 26 and the chassis 12 is 10:1, and the rotation ratio of the servo motor 13 and the control motor 27 is 1:10, when the chassis 12 moves upward, the changed volume of the inner tank 4 is always equal to the changed volume in the sampling box 22, and then the liquid medicine in the inner tank 4 enters the sampling box 22, and the pressure inside the sampling box 22 will not change due to the change in the internal volume of the inner tank 4 driven by the chassis 12.

[0042] During use, when the staff needs to take out some liquid medicine from the inner tank 4 as a sample for testing, by controlling the reverse rotation of the servo motor 13, and the reverse rotation of the servo motor 13 drives the control motor 27 to rotate (the rotation ratio of the two is 1:10), the servo motor 13 drives the chassis 12 to move upward through the driving rod 14 and the threaded rod 15, and the control motor 27 drives the driven gear 29 to rotate through the driving gear 28, thereby driving the control rod 25 in the horizontal direction, so that the volume change of the inner tank 4 driven by the upward movement of the chassis 12 is equal to the volume change caused by the movement of the movable plate 26 inside the sampling box 22. At this time, the liquid medicine inside the inner tank 4 flows into the sampling box 22 with the upward movement of the chassis 12, completing the first step of the sampling work.

[0043] The remaining structures are the same as those of Example 1.

[0044] Example 3, reference Figure 8 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the sample assembly includes a threaded groove opened at the lower end of the sampling box 22, a sampling tube 30 threadedly installed in the threaded groove, a piston rod 31 slidably installed at the lower end of the sampling tube 30, and a piston plate 32 fixedly installed at the upper end of the piston rod 31. The piston plate 32 is slidably installed on the inner wall of the sampling tube 30, and the shape and size of the end face of the piston plate 32 is equal to the size of the inner wall end face of the sampling tube 30. The area ratio of the piston plate 32 to the movable plate 26 is 1:3.

[0045] Specifically, the sample assembly is used to sample the liquid medicine inside the sampling box 22, and the air inside the sampling tube 30 is discharged through the movable plate 26. At the same time, when the movable plate 26 moves beyond the thread groove, the liquid medicine inside the sampling box 22 flows into the piston plate 32 under the subsequent pressure, and generates downward pressure on the piston plate 32, so that the piston plate 32 slides downward along the sampling tube 30. When the piston plate 32 moves downward and the gas in the sampling tube 30 is discharged, the sample liquid medicine can be collected in the sampling tube 30, and the sampling of the liquid medicine is completed. The area ratio of the piston plate 32 to the movable plate 26 is 1:3, so that the liquid medicine in the sampling box 22 can completely fill the sampling tube 30, which is convenient for subsequent sampling and detection. After the sampling is completed, the motor 27 is reversed to control the movable plate 26 to be in its original position. The movable plate 26 pushes the liquid medicine inside the sampling box 22 into the inner tank 4 for storage, while facilitating the subsequent removal of the sampling tube 30 from the threaded groove. This sampling method can ensure that the interior of the inner tank 4 is always in a closed state when sampling the liquid medicine in the inner tank 4.

[0046] During use, when the medicine liquid flows into the sampling box 22 and the movable plate 26 slides beyond the threaded groove, the medicine liquid inside the sampling box 22 continues to move upward with the chassis 12, and the medicine liquid enters the sampling tube 30 under the action of pressure, and generates downward pressure on the piston plate 32, causing the piston plate 32 to slide downward under the action of pressure. During the downward sliding of the piston plate 32, the air in the sampling tube 30 is discharged, and the medicine liquid is collected inside the sampling tube 30 to complete the sampling of the medicine liquid. After the sampling is completed, the control motor 27 is reversed, and the control motor 27 is reversed to reset the movable plate 26. At this time, the staff can take the sampling tube 30 out of the threaded groove, and during the sampling process, the interior of the inner tank 4 is always in a closed state, which will not affect the subsequent storage effect.

[0047] The remaining structure is the same as that of Example 2.

[0048] Based on Examples 1-3, the working principle of the present invention is as follows: the staff passes the produced soft capsule liquid into the inner tank 4 through the liquid discharge port 7, and closes the liquid discharge port 7, and extracts the air in the inner tank 4 through the vacuum pump, so that the inner tank 4 is in a vacuum state, and turns on the servo motor 13, so that the driving end of the servo motor 13 rotates slowly in the positive direction, and then drives the turntable 17 at the upper end to rotate slowly and synchronously through the driving rod 14 and the threaded rod 15, and the stirring rod 21 on the turntable 17 rotates synchronously to slowly stir the liquid medicine in the inner tank 4, so as to prevent the liquid medicine from being deposited and agglomerated due to long-term storage, and avoid uneven distribution of the liquid medicine.

[0049] When the staff needs to take out some liquid medicine from the inner tank 4 as a sample for testing, by controlling the reverse rotation of the servo motor 13, and the reverse rotation of the servo motor 13 drives the control motor 27 to rotate (the rotation ratio of the two is 1:10), the servo motor 13 drives the chassis 12 to move upward through the driving rod 14 and the threaded rod 15, and the control motor 27 drives the driven gear 29 to rotate through the driving gear 28, thereby driving the control rod 25 along the horizontal direction, so that the volume change of the inner tank 4 driven by the upward movement of the chassis 12 is equal to the volume change caused by the movement of the movable plate 26 inside the sampling box 22. At this time, the liquid medicine inside the inner tank 4 flows into the sampling box 22 as the chassis 12 moves upward.

[0050] When the medicine liquid flows into the sampling box 22 and the movable plate 26 slides beyond the threaded groove, the medicine liquid inside the sampling box 22 continues to move upward with the chassis 12. The medicine liquid enters the sampling tube 30 under the action of pressure and generates downward pressure on the piston plate 32, causing the piston plate 32 to slide downward under the action of pressure. During the downward sliding of the piston plate 32, the air in the sampling tube 30 is discharged and the medicine liquid is collected in the sampling tube 30 to complete the sampling of the medicine liquid. After the sampling is completed, the control motor 27 is reversed, and the control motor 27 is reversed to reset the movable plate 26. At this time, the staff can take the sampling tube 30 out of the threaded groove, and during the sampling process, the interior of the inner tank 4 is always in a closed state, which will not affect the subsequent storage effect.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
