[0001] The invention relates to the technical field of capsules, and in particular to a detection device for hollow capsules with an anti-deformation porous structure. Background Art

[0002] Hollow capsules are containers mainly used for holding solid and liquid drugs, consisting of a cap and a body made of pharmaceutical gelatin and excipients. They solve the problem of drugs being difficult to take and having a bad taste, and truly make good medicine no longer bitter. Hollow capsules are becoming more and more popular. First of all, the shape of the capsules is slender and easy to swallow, making them the most popular dosage form among consumers. In addition, the capsules can effectively cover up the unpleasant taste and odor of the contents. As a result, hollow capsules have been widely used in the pharmaceutical, food, cosmetics and other industries. Furthermore, the widespread use of hollow capsules has led to continuous innovation in their production and improvement.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-Figure 14 This application is described in further detail.

[0035] The embodiment of the present application discloses a deformation-resistant porous structure hollow capsule detection device, which is mainly used in the production and preparation process of hollow capsules.

[0036] The existing hollow capsules have a hollow structure for containing drugs, which makes them easy to deform, causing the contents to be easily contaminated, and the capsule shell hinders the diffusion of the drugs, which easily causes drug blockage and discomfort.

[0037] Secondly, in the prior art, the appearance defects of the capsules are often detected, and the capsules are usually assembled, and the prior art cannot effectively detect the sealing of the capsules, and the capsules may leak after production.

[0038] In addition, when the capsule is tested, its contents are in liquid, solid and powder states, and the existing technology often does not perform differentiated testing, resulting in all capsules using the same technology and equipment, resulting in inaccurate test results during the capsule testing process.

[0039] Therefore, the present application proposes an anti-deformation porous structure hollow capsule detection device to solve the above problems.

[0040] First, the present invention provides a hollow capsule with a porous structure that resists deformation. Figure 1 and Figure 2 As shown, it includes a capsule body 1 and a capsule cap 2. The capsule cap 2 is movably connected to the capsule body 1, and the outer wall of the capsule body 1 fits with the inner wall of the capsule cap 2.

[0041] The porous structure of the hollow capsule reduces the weight of the hollow capsule, facilitates drug diffusion, and improves the stability of the capsule in the external environment. The diffusion hemispherical protrusion can increase the speed of drug entry into the human body, thereby avoiding the discomfort caused by drug blockage and improving the comfort of use.

[0042] A hollow capsule is a container mainly used for holding solid and liquid drugs, which consists of a capsule cap 2 and a capsule body 1 made of pharmaceutical gelatin and excipients. It solves the problem of difficult to take the drug and poor taste for the user, and truly realizes that good medicine is no longer bitter. Hollow capsules are becoming more and more popular. First of all, the shape of the capsule is slender and easy to swallow, which is the most popular dosage form among consumers; in addition, the capsule can effectively cover up the unpleasant taste and odor of the contents. Therefore, hollow capsules have been widely used in the pharmaceutical, food, cosmetics and other industries.

[0043] The hollow capsule comprises a capsule body 1 and a capsule cap 2, wherein the capsule cap 2 is movably connected to the capsule body 1, and the outer wall of the capsule body 1 fits with the inner wall of the capsule cap 2; two circles of connecting grooves 11 are provided on the inner wall of the capsule cap 2, and a circle of annularly distributed connecting hemispherical protrusions 10 are provided at the outer end of the capsule body 1, and the connecting hemispherical protrusions 10 are correspondingly arranged to the connecting grooves 11, and the connecting hemispherical protrusions 10 are snap-fitted with the hollow capsule cap 2, so that the capsule cap 2 is firmly connected to the capsule body 1 and is not easy to fall off.

[0044] See also Figure 3 As shown, a support rod frame assembly 12 is provided inside the capsule body 1, and the support rod frame assembly 12 is connected to the hollow capsule body 1 as a whole, and the cross section of the support rod frame assembly 12 is triangular fork-shaped. A plurality of evenly distributed diffusion hemispherical protrusions 13 are provided on the outer wall of the capsule body 1, and each diffusion hemispherical protrusion 13 is provided on the side of the capsule body 1 away from the capsule cap 2; the diffusion hemispherical protrusion 13 can increase the speed of the drug entering the human body, thereby avoiding the discomfort caused by drug blockage and improving the comfort of use.

[0045] Most of the current hollow capsules are non-porous structures, which are not conducive to drug diffusion, but the porous structure is not stable enough in the outside world. Therefore, the present application proposes a porous structure of a hollow capsule, wherein the capsule body 1 and the capsule cap 2 both include a modified coating, a porous matrix, an antibacterial inner capsule and a moisture-proof inner membrane, wherein the antibacterial inner capsule is arranged on the inner side of the porous matrix, and the moisture-proof inner membrane is arranged on the inner side of the antibacterial inner capsule, and the porous matrix, the antibacterial inner capsule and the moisture-proof inner membrane are all arranged as one. The porous structure reduces the weight of the hollow capsule, which facilitates drug diffusion. At the same time, the modified coating, the antibacterial inner capsule and the moisture-proof inner membrane optimize the protective measures of the porous structure, thereby improving the stability of the capsule in the external environment.

[0046] In addition, the porous structure preparation method for the porous capsule is as follows: 1. Mix the raw materials of capsules such as pullulan, carrageenan, coagulant, biocatalyst, thickener and plasticizer with sodium bicarbonate to make an aqueous solution. Select biodegradable polymers such as polylactic acid (PLA) and polyhydroxyalkanoates (PHAs) as capsule material excipients. Modify the materials by copolymerization, cross-linking and adding nanofillers to improve their toughness and pressure resistance while reducing their density.

[0047] 2. Stirring at a temperature below 70°C for 1 to 2 hours, followed by filtering, standing and heat preservation, degassing, dipping in glue and post-treatment to obtain Rulan polysaccharide non-porous hollow capsules. Finally, heating at a temperature above 110°C, preferably above 130°C, with a heating rate of 5°C / s or more, a heating time of 10s to 1min, and then rapidly cooling to room temperature to obtain capsules with pores.

[0048] 3. Through coating technology, the hydrophilicity or hydrophobicity of the capsule shell surface is increased to improve its stability under specific conditions.

[0049] Furthermore, in view of the fact that my country currently mainly uses ethylene oxide sterilization technology in the production of medical devices and drugs, and that ethylene oxide is highly toxic, long-term exposure will pose certain risks and hidden dangers to the health of medical staff and patients, and there will be residues during the sterilization process, we independently developed cobalt-60 irradiation sterilization technology.

[0050] 1. Determine the appropriate irradiation dose for capsules using the Diamond 60 irradiation sterilization technology, as well as the distribution of the irradiation dose inside the capsule, to ensure that all microorganisms in the capsule can be effectively killed, so that the irradiation dose should be able to effectively kill the microorganisms in the capsule while avoiding adverse effects on the capsule material and product quality.

[0051] 2. Research and design appropriate dose control and monitoring systems to ensure that the dose during the irradiation process is accurate and controllable, including calibration of irradiation equipment, real-time monitoring of the irradiation process, and recording and tracing of irradiation doses.

[0052] 3. Optimize the key parameters in the cobalt 60 irradiation sterilization process, such as irradiation speed, irradiation distance, irradiation angle, etc., to achieve the best sterilization effect and product quality. Take 3 groups of empty capsules, the experimental group is sterilized by cobalt 60 irradiation, the control group 1 is not sterilized, and the control group 2 is sterilized by ethylene oxide. The other conditions are the same. The experimental results are as follows: It can be seen from the experimental results that the cobalt 60 irradiation sterilization effect is excellent and there is no residue.

[0053] In view of the fact that the use of ethylene oxide to sterilize hollow capsules will pose certain risks and hidden dangers to the health of medical staff and patients, and there will be residues during the sterilization process, we have independently developed cobalt 60 irradiation sterilization technology. The capsules to be sterilized are placed in the cobalt 60 irradiation equipment and sterilized by gamma rays or electron radiation. During the irradiation process, the irradiation dose is monitored and controlled by a dose control and monitoring system to ensure the sterilization effect.

[0054] Embodiment 1: The present application also proposes a hollow capsule detection device with an anti-deformation porous structure.

[0055] See also Figure 4 , Figure 5 and Figure 6 As shown, the anti-deformation porous structure hollow capsule detection equipment includes a stationary portable detection box 3, and a plurality of feed ports 30 for the capsule body 1 and the capsule cap 2 to enter are opened at the upper end of the portable detection box 3, and a detection part 4 for detecting the stability of the connection between the capsule body 1 and the capsule cap 2 is arranged inside the portable detection box 3.

[0056] An opening and closing baffle 31 for opening and closing the material inlet 30 at the upper end of the portable detection box 3 is provided, and a vertical downward conveying pipe 32 abuts against the material inlet 30 of the portable detection box 3 .

[0057] It should be noted that the portable detection box 3 in the present application has three feed ports 30, wherein the feed port 30 on one side is mainly used to detect hollow capsules with solid contents inside; the feed port 30 on the other side is mainly used to detect hollow capsules with liquid contents inside.

[0058] During the specific implementation process, when testing the hollow capsules with liquid contents, first, they are placed from the portable testing box 3 to the feed port 30 of the liquid content capsules, and then the hollow capsules with liquid contents enter the testing turntable 40 inside the portable testing box 3 along the conveying pipe 32.

[0059] After the hollow capsule falls to the upper end of the detection turntable 40, it is transported to a designated position and then controlled to rotate centrifugally. Under high-speed rotation, the tightness of the connection between the capsule body 1 and the capsule cap 2 of the hollow capsule is detected to simulate whether the liquid content in the entire hollow capsule leaks during collision, falling and transportation.

[0060] Look again Figure 6 As shown, an opening and closing baffle 31 is provided at the feed inlet 30 at the upper end of the portable testing box 3, and a vertically downward conveying pipe 32 abuts against the feed inlet 30 of the portable testing box 3. The opening and closing baffle 31 is used to shield the feed inlet 30 at the upper end of the portable testing box 3 to prevent external dust and debris from falling into the portable testing box 3 and affecting the detection of the hollow capsules.

[0061] Reference Figure 7 and Figure 8 As shown, that is, a schematic diagram of the structure for detecting hollow capsules in the present application; specifically, the detection part 4 includes a detection turntable 40, a working groove 41, a clamping plate 42, a scissor assembly 43 and an electric push rod 44.

[0062] The detection turntable 40 is evenly distributed inside the portable detection box 3 along the length direction, and the detection turntable 40 is corresponding to the feed port 30. A working groove 41 is opened on the detection turntable 40. Clamping plates 42 are symmetrically arranged in the working groove 41 of the detection turntable 40. A scissors-type assembly 43 is connected to the clamping plate 42. An electric push rod 44 is arranged at the bottom of the detection turntable 40, and the output end of the electric push rod 44 is connected to one side of the scissors-type assembly 43.

[0063] It should be noted that one end of the two scissor-type assemblies 43 on the clamping plate 42 is hinged on one side of the clamping plate 42, and the other end of the scissor-type assemblies 43 is slidably set on the other side of the clamping plate 42. The purpose is to ensure the normal opening and closing of the scissor-type assemblies 43 and control the movement of the clamping plate 42.

[0064] The detection turntable 40 is provided with a visual detector.

[0065] It should be noted that the visual detector in the present application mainly detects the positions of the capsule body 1 and the capsule cap 2 of the hollow capsule, which is an existing known structure.

[0066] During the specific implementation, after the hollow capsule falls onto the detection turntable 40, the visual detector is started. After the visual detector detects the position of the capsule cap 2, the control component 9 is started. The control component 9 starts to control the hollow capsule to move along the length direction of the working groove 41 until the capsule cap 2 of the hollow capsule moves to the edge of the detection turntable 40 and the capsule cap 2 of the hollow capsule is suspended in the air. At this time, the electric push rod 44 is started, and the output end of the electric push rod 44 moves, which drives the two clamping plates 42 to approach each other through the scissor assembly 43 until the two clamping plates 42 clamp the capsule body 1 of the hollow capsule. At this time, the capsule body 1 of the hollow capsule is clamped and limited, and the capsule cap 2 of the hollow capsule is suspended in the air.

[0067] At this point, the preliminary preparations for the hollow capsule detection are completed. However, it should be noted that the control component 9 of the present application can move in both positive and negative directions, and when the visual detector detects that the capsule cap 2 of the hollow capsule is at a certain position, the corresponding control component 9 drives the hollow capsule to move in the corresponding direction, thereby avoiding the situation of flipping the hollow capsule and facilitating the capsule cap 2 of the hollow capsule to be suspended in the air.

[0068] See also Fig. 9 and Fig.10 As shown, a liquid detection component 7 is also provided on one side of the interior of the portable detection box 3. The liquid detection component 7 includes a feed bin 70 and a discharge bin 71. The feed bin 70 and the discharge bin 71 are arranged on the portable detection box 3, and storage rollers 72 are rotatably installed in the feed bin 70 and the discharge bin 71. The storage rollers 72 are provided with a color-changing detection belt 73 that changes speed when encountering liquid. Two symmetrically distributed reversing shafts 74 are provided on the periphery of the detection turntable 40 located on one side in the portable detection box 3. The two reversing shafts 74 limit the color-changing detection belt 73 so that the color-changing detection belt 73 is circular and surrounds the periphery of the detection turntable 40.

[0069] The reversing shaft 74 is tilted so that the color-changing detection belt 73 surrounding the periphery of the detection turntable 40 is distributed in a cone shape.

[0070] In the initial state, one end of the color-changing detection belt 73 is wound on the storage roller 72 of the discharge bin 71, and the other end of the color-changing detection belt 73 is wound on the storage roller 72 of the feed bin 70. The color-changing detection belt 73 is limited by the limiting ring 75 on the periphery of the detection turntable 40, so that the middle part of the color-changing detection belt 73 is exposed on the periphery of the detection turntable 40. When the hollow capsule containing liquid contents rotates at a high speed, if the capsule cap 2 of the hollow capsule is detached, the liquid contents filled inside it will splash onto the color-changing detection belt 73, causing it to have an obvious color-changing effect, thereby facilitating the operator to observe the color change of the color-changing detection belt 73 and quickly determine the detection result of the hollow capsule.

[0071] Furthermore, the adjusting knob 60 can be slowly rotated to gradually increase the rotation speed of the detection turntable 40 from low to high, so as to detect the sealing performance of the hollow capsule at different rotation speeds until the maximum centrifugal force that can be borne by the capsule body 1 and the capsule cap 2 of the hollow capsule to separate the two is detected.

[0072] In the above, the hollow capsules with liquid contents are mainly tested, but the contents inside the hollow capsules are also solid particles and powders. Therefore, when testing the hollow capsules with solid contents and powdery contents, the following method is used for testing, as shown below: See also Fig.11 As shown, a solid detection member 8 is also provided on one side of the interior of the portable detection box 3. The solid detection member 8 includes a baffle 80 provided on the periphery of the detection turntable 40 on the other side of the interior of the portable detection box 3. The baffle 80 is distributed obliquely.

[0073] A material discharge port 82 is formed on one side of the baffle plate 80 , and a weighing device 83 is disposed at the material discharge port 82 .

[0074] When the detection turntable 40 rotates at a high speed, if the capsule body 1 and the capsule cap 2 of the hollow capsule are separated, the solid particles and powdered materials inside will diffuse outward and be blocked and collected by the baffle 80. The solid particles or powders slide down along the baffle 80 onto the weighing device 83; if weighing data appears on the weighing device 83, it means that the capsule body 1 and the capsule cap 2 of the hollow capsule are separated; if no weighing data appears on the weighing device 83, it means that the capsule body 1 and the capsule cap 2 of the hollow capsule are not separated.

[0075] Embodiment 2: In order to further improve the accuracy of hollow capsule detection, the present application also proposes a speed change mechanism 5 , which can realize the sealing detection of the hollow capsule by controlling the rotation speed of the detection turntable 40 .

[0076] Reference Fig.12 , Fig.13 and Fig.14 As shown, that is, a schematic diagram of the structure for controlling the rotation of the detection turntable 40 in the present application; specifically, a connecting column 50 is installed at the bottom of the detection turntable 40, an adjusting column 51 is installed on the inner wall of the portable detection box 3, and a speed change mechanism 5 is connected between the connecting column 50 and the adjusting column 51, and the speed change mechanism 5 includes two groups of corresponding speed change parts 52, and a speed change steel belt 53 is sleeved between the two groups of speed change parts 52, and one group of speed change parts 52 is arranged on the connecting column 50, and the other group is arranged on the adjusting column 51, and the speed change parts 52 on the adjusting column 51 are connected to a driving motor 54.

[0077] The driving motor 54 is disposed on the inner wall of the portable detection box 3 , and an output end of the driving motor 54 is connected to the adjusting column 51 .

[0078] Each set of speed change components 52 includes two symmetrically distributed speed change cone wheels 55 . A cross slot 56 is provided on the connecting column 50 and the adjusting column 51 . The speed change cone wheels 55 are slidably arranged on the cross slots 56 of the connecting column 50 and the adjusting column 51 .

[0079] During the specific implementation, the drive motor 54 is started, and the output end of the drive motor 54 controls the adjustment column 51 to rotate. The adjustment column 51 controls the connection column 50 to rotate through the speed change member 52 and the speed change steel belt 53. During the rotation, the connection column 50 drives the detection turntable 40 at its upper end to rotate, so that the detection turntable 40 rotates. During the rotation of the detection turntable 40, the hollow capsule clamped at its upper end rotates synchronously, and the liquid content inside the hollow capsule approaches the direction of the capsule cap 2 due to the centrifugal effect, until the liquid content all rests on one end of the capsule cap 2 of the hollow capsule. At this time, the force applied to the capsule cap 2 is its own centrifugal force and the centrifugal force of its internal contents.

[0080] If there is no liquid leakage at the connection between the capsule cap 2 and the capsule body 1, it means that the connection performance between the capsule cap 2 and the capsule body 1 is strong; if there is liquid leakage at the connection between the capsule cap 2 and the capsule body 1, it means that the sealing performance of the connection between the two is poor.

[0081] See also Figure 6 and Fig.12 As shown, it is a structural schematic diagram of adjusting the rotation speed of the detection turntable 40 in the present application; an adjusting knob 60 is rotatably installed on the portable detection box 3, an adjusting plate is arranged at the bottom of the adjusting knob 60, an adjusting groove is opened on the adjusting plate, a lifting column is abutted in the adjusting groove, and the lifting column is installed on a vertical plate 64, and the vertical plate 64 is slidably arranged on the inner wall of the portable detection box 3 along the height direction of the portable detection box 3, and the bottom of the vertical plate 64 is rotatably connected to the speed change cone wheel 55.

[0082] It should be noted that the feed port 30 and the conveying pipe 32 in the present invention are relatively large in size and can be used to convey hollow capsules of different sizes.

[0083] When performing performance tests on hollow capsules of different sizes, the strength of the card receiving force between the capsule body 1 and the capsule cap 2 of the hollow capsules is different due to the different sizes. Therefore, it is necessary to adjust the rotation speed of the detection turntable 40 to adjust the centrifugal force of the hollow capsules during rotation.

[0084] When it comes to hollow capsules with larger sizes, turn the adjustment knob 60 clockwise, and the adjustment plate at the bottom of the adjustment knob 60 presses down the lifting column through the adjustment groove, so that the lifting column and the vertical plate 64 move downward synchronously. When the vertical plate 64 moves downward, it controls the center gear 65 to rotate, and then the center gear 65 drives the synchronous plate 67 to move upward through the center rod 66, and the vertical plate 64 and the synchronous plate 67 are in the same straight line, and the two are relatively close. At this time, the vertical plate 64 and the synchronous plate 67 control the two speed-changing cone wheels 55 to approach each other, forcing the circumferential radius of the speed-changing steel belt 53 close to the drive motor 54 to increase, and the circumferential radius of the speed-changing steel belt 53 on the two speed-changing cone wheels 55 close to the detection turntable 40 becomes smaller. At this time, after the drive motor 54 rotates, the rotation speed of the detection turntable 40 will be increased to ensure the high-speed rotation of the detection turntable 40, thereby indirectly increasing its centrifugal force. The centrifugal force on the hollow capsule is adjusted by adjusting the rotation speed of the detection turntable 40.

[0085] One side of the vertical plate 64 is a sawtooth structure, and the sawtooth structure of the vertical plate 64 is meshed with a center gear 65 rotating on the inner wall of the portable detection box 3, and the other side of the center gear 65 is meshed with a center rod 66, and a synchronization plate 67 is installed on the center rod 66, and the synchronization plate 67 rotates on the speed cone wheel 55 at the bottom of each group of speed change parts 52; the two speed cone wheels 55 close to the detection turntable 40 are abutted with gaskets 68, and the gaskets 68 are provided with a limit compression spring 69 sleeved on the connecting column 50.

[0086] It should be noted that, in the initial state, the limit compression spring 69 presses the two speed-changing cone wheels 55 close to the detection turntable 40 , so that the two speed-changing cone wheels 55 press the speed-changing steel belt 53 .

[0087] Therefore, when the detection turntable 40 needs to be controlled to rotate at a high speed, the two speed-changing cone wheels 55 close to the detection turntable 40 can be moved away from each other; when the detection turntable 40 needs to be controlled to rotate at a low speed, the two speed-changing cone wheels 55 close to the detection turntable 40 can be moved close to each other.

[0088] During operation: In the first step, when testing the hollow capsules with liquid contents, the capsules are placed from the portable testing box 3 to the feed port 30 of the liquid contents capsules, and then the hollow capsules with liquid contents enter the testing turntable 40 inside the portable testing box 3 along the conveying pipe 32.

[0089] Step 2: After the hollow capsule falls to the upper end of the detection turntable 40, it is transported to a designated position and then controlled to rotate centrifugally. Under high-speed rotation, the tightness of the connection between the capsule body 1 and the capsule cap 2 of the hollow capsule is detected to simulate whether the liquid content in the entire hollow capsule leaks during collision, falling and transportation.

[0090] Step 3: Start the visual detector. After the visual detector detects the position of the capsule cap 2, it starts the control component 9. The control component 9 starts to control the hollow capsule to move along the length direction of the working groove 41 until the capsule cap 2 of the hollow capsule moves to the edge of the detection turntable 40, and the capsule cap 2 of the hollow capsule is suspended in the air. At this time, the electric push rod 44 is started, and the output end of the electric push rod 44 moves, which drives the two clamping plates 42 to approach each other through the scissor assembly 43 until the two clamping plates 42 clamp the capsule body 1 of the hollow capsule. At this time, the capsule body 1 of the hollow capsule is clamped and limited, and the capsule cap 2 of the hollow capsule is suspended in the air.

[0091] Step 4: Start the drive motor 54. The output end of the drive motor 54 controls the adjustment column 51 to rotate. The adjustment column 51 controls the connection column 50 to rotate through the speed change member 52 and the speed change steel belt 53. During the rotation, the connection column 50 drives the detection turntable 40 at its upper end to rotate, so that the detection turntable 40 rotates. During the rotation of the detection turntable 40, the hollow capsule clamped at its upper end rotates synchronously, and the liquid content inside the hollow capsule approaches the direction of the capsule cap 2 due to the centrifugal effect, until the liquid content all rests on one end of the capsule cap 2 of the hollow capsule. At this time, the force applied to the capsule cap 2 is its own centrifugal force and the centrifugal force of its internal contents.

[0092] If there is no liquid leakage at the connection between the capsule cap 2 and the capsule body 1, it means that the connection performance between the capsule cap 2 and the capsule body 1 is strong; if there is liquid leakage at the connection between the capsule cap 2 and the capsule body 1, it means that the sealing performance of the connection between the two is poor.

[0093] Step 5: For hollow capsules with liquid contents, when the hollow capsules containing liquid contents are rotated at high speed, if the capsule cap 2 of the hollow capsule is detached, the liquid contents filled inside will splash onto the color-changing detection belt 73, causing it to change color significantly, thereby making it easier for the operator to observe the color change of the color-changing detection belt 73 and quickly determine the detection result of the hollow capsule.

[0094] Step 6: For hollow capsules containing solid particles and powdery materials, when the detection turntable 40 rotates at a high speed, if the capsule body 1 and the capsule cap 2 of the hollow capsule are separated, the solid particles and powdery materials inside will diffuse outward and be blocked and collected by the baffle 80. The solid particles or powder slide down along the baffle 80 onto the weighing device 83; if weighing data appears on the weighing device 83, it means that the capsule body 1 and the capsule cap 2 of the hollow capsule are separated; if no weighing data appears on the weighing device 83, it means that the capsule body 1 and the capsule cap 2 of the hollow capsule are not separated.

Therefore, all equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
