Description

Technical Field

[0001] This application relates to the technical field of tablet hardness detection, specifically an automatic tablet hardness detection device. Background Art

[0002] In the production and manufacturing process of tablet drugs, the quality of drug tablets will directly affect their efficacy and medication safety. Physical inspections include appearance, mass difference, hardness, disintegration time limit, and packaging conditions, etc. When the tablets are of appropriate hardness, they can prevent breakage or wear during packaging, transportation, etc. The hardness of the tablets is also closely related to their disintegration and dissolution. Therefore, random hardness inspections are required after tablet production is completed.

[0003] Chinese Patent Grant Publication No.: CN220170789U discloses a tablet drug hardness detector. When drug residues appear on the detector main body and need to be cleaned after detection, the fan is started and the wind blows out from the dust blowing pipe. At the same time, the electric telescopic rod is started to drive the push block to slide the residue through the inclined plate into the dust collection box, improving the processing efficiency of the residue.

[0004] However, in the above solution, although the cooperation of the fan and the electric telescopic rod is used to collect the residues after tablet hardness detection, this design not only has a complex structure and increases the cost burden, but also because the wind generated by the fan may cause tiny tablet residues to disperse during collection and cannot be effectively collected, resulting in a reduction in collection efficiency and also causing environmental pollution.

[0005] Therefore, it is necessary to provide an automatic tablet hardness detection device to solve the above problems.

[0006] It should be noted that the above information disclosed in this background art section is only used to understand the background art of the concept of this application, and therefore, it may include information that does not constitute prior art. Utility Model Content

[0007] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide an automatic tablet hardness detection device. After detection, the hydraulic cylinder controls the push rod to move upward. At this time, the adsorption force between the magnet and the magnetic part causes the limiting block to slide in the limiting groove, resulting in the tilting of the bearing plate. As a result, the broken tablet residues smoothly flow into the collection tank through the discharge port, realizing the automatic collection of tablet residues. This process facilitates the subsequent processing and cleaning work, improves the collection efficiency, and effectively reduces the dispersion of tiny tablet residues during collection. In addition, when the limiting block slides to the highest position, the magnet and the magnetic part are separated, and the bearing plate automatically returns to the initial position under the action of gravity, preparing for the next test. Its structure is simple and has strong linkage, not only reducing the cost, but also improving the convenience and efficiency of operation.

[0008] The technical solution adopted by this application to solve its technical problems is: an automatic tablet hardness detection device, including: a base, a bearing assembly, and a pair of adsorption assemblies. A support plate is installed on the top of the base, and a collection groove is opened on the top of the base. An installation plate is installed on one side of the support plate, a hydraulic cylinder is installed on the top of the installation plate, a push rod is installed at the bottom of the hydraulic cylinder, a pressure sensor is installed at the bottom end of the push rod, and a pressure head is installed at the sensing end of the pressure sensor. The bearing assembly includes a bearing plate rotatably connected to the top of the base. A placement groove and a discharge port that communicate with each other are respectively opened on the top of the bearing plate. Limiting grooves are opened on both sides of the bearing plate, limiting blocks are installed in the limiting grooves, and magnetic members are installed on one side of the limiting blocks. A pair of adsorption assemblies are respectively installed on both sides of the push rod. The adsorption assembly includes a connecting rod, and a magnet is installed at one end of the connecting rod.

[0009] Further, a pair of hinges are installed on one side of the bearing plate, and the bearing plate is rotatably connected to the top of the base through the hinges.

[0010] Further, the limiting groove is inclined.

[0011] Further, a collection box is also installed on one side of the base, and a reserved hole is opened on one side of the base. The collection box passes through the reserved hole and extends into the collection groove.

[0012] Further, a slider is installed at the end of the connecting rod away from the magnet. A pair of sliding grooves are opened on the outer circumference of the push rod, and the slider is slidably connected to the sliding grooves.

[0013] Further, an installation groove is opened on the top of the base, and a rubber pad is installed in the installation groove. The rubber pad abuts against the bottom of the bearing plate.

[0014] The beneficial effects of this application are: for the automatic tablet hardness detection device provided by this application, after the detection is completed, the hydraulic cylinder controls the push rod to move upward. At this time, the adsorption force between the magnet and the magnetic member causes the limiting block to slide in the limiting groove, resulting in the inclination of the bearing plate, and then enabling the broken tablet residues to smoothly flow into the collection groove through the discharge port, realizing the automatic collection of tablet residues. This process facilitates the subsequent processing and cleaning work, improves the collection efficiency, and effectively reduces the phenomenon of tiny tablet residues floating during the collection process. In addition, when the limiting block slides to the highest position, the magnet and the magnetic member are separated, and the bearing plate automatically returns to the initial position under the action of gravity, preparing for the next test. Its structure is simple and has strong linkage, not only reducing costs, but also improving the convenience and efficiency of operation.

[0024] In order to enable those skilled in the art to better understand the solution of this application, the following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of this application.

[0025] Such as Figures 1-4As shown in the figure, the present application provides an automatic tablet hardness detection device, including: a base 1, a carrying component 6 and a pair of adsorption components 9. A support plate 2 is installed on the top of the base 1. The support plate 2 is fixed to the base 1 by bolts, and a collection groove 10 is provided on the top of the base 1. An installation plate 3 is installed on one side of the support plate 2. The installation plate 3 is installed on one side of the support plate 2 by welding. A hydraulic cylinder 4 is installed on the top of the installation plate 3. The hydraulic cylinder 4 is installed on the top of the installation plate 3 by bolts. A push rod 5 is installed at the bottom of the hydraulic cylinder 4. A pressure sensor 7 is installed at the bottom end of the push rod 5. A pressing head 8 is installed at the sensing end of the pressure sensor 7. The carrying component 6 includes a carrying plate 61 rotatably connected to the top of the base 1. A placement groove 63 and a discharge port 64 communicating with each other are respectively provided on the top of the carrying plate 61. Limiting grooves 65 are provided on both sides of the carrying plate 61. Limiting blocks 66 are installed in the limiting grooves 65. The limiting blocks 66 are adapted to the limiting grooves 65. The limiting blocks 66 can slide in the limiting grooves 65. A magnetic member 67 is installed on one side of the limiting block 66. The magnetic member 67 is rotatably connected to the limiting block 66. A pair of adsorption components 9 are respectively installed on both sides of the push rod 5. The adsorption component 9 includes a connecting rod 91. A magnet 93 is installed at one end of the connecting rod 91.

[0026] This solution determines the hardness of the tablet by applying a vertical force to the tablet and measuring the resulting pressure, and is used to evaluate the quality characteristics of the tablet, such as its anti-cracking performance and solubility.

[0027] Specifically, the tablet to be detected is placed in the placement groove 63 on the top of the carrying plate 61. At this time, the hydraulic cylinder 4 is started to control the push rod 5 to move downward, and the pressure sensor 7 and the pressing head 8 are moved downward to the surface of the tablet and pressure is applied. The pressure sensor 7 can detect the pressure value of the pressing head 8, so as to detect the tablet hardness by monitoring the degree of pressure in real time. At the same time, the magnet 93 can be adsorbed to the magnetic member 67. After the detection is completed, the hydraulic cylinder 4 can be used to control the push rod 5 to move upward. Since the magnet 93 and the magnetic member 67 are adsorbed to each other, the magnet 93 can drive the limiting block 66 on one side of the magnetic member 67 to slide in the limiting groove 65, so as to realize the rotation of the carrying plate 61, causing the carrying plate 61 to tilt. The broken tablet residues in the placement groove 63 can be discharged into the collection groove 10 through the discharge port 64 under the guidance of the inclined plane, so as to achieve the purpose of automatically collecting the tablet residues. Until the limiting block 66 slides to the highest position, the magnet 93 and the magnetic member 67 are separated, and the carrying plate 61 automatically resets under the action of gravity, preparing for the next test. Its structure is simple, the linkage is strong, and the cost is reduced.

[0028] Among them, the magnetic member 67 is made of a magnetic material, preferably iron, which has good magnetic conductivity and can generate an attractive force with the magnet 93, so that the magnetic member 67 and the magnet 93 are adsorbed to each other.

[0029] It should be noted that the device is also connected to an external display screen for displaying the detection data.

[0030] As Figure 4 shown, a pair of hinges 62 are installed on one side of the bearing plate 61, and the bearing plate 61 is rotatably connected to the top of the base 1 through the hinges 62. The provided hinges 62 are respectively connected to the bearing plate 61 and the base 1 by bolts, thereby realizing the rotation of the bearing plate 61 on the top of the base 1.

[0031] As Figure 4 shown, the limiting groove 65 is inclined. When the limiting block 66 slides to the limit, the magnet 93 is separated from the magnetic member 67, and the limiting block 66 slides down to the lowest position under the action of gravity.

[0032] It should be noted that in the initial state, the limiting block 66 is at the lowest position of the limiting groove 65. At this time, the position of the magnetic member 67 on one side of the limiting block 66 corresponds to the position of the magnet 93, so as to ensure that when the push rod 5 moves vertically downward, the magnet 93 can be adsorbed to the magnetic member 67.

[0033] In one embodiment, as Figures 1-2 shown, a collection box 11 is also installed on one side of the base 1, and a reserved hole is provided on one side of the base 1. The collection box 11 passes through the reserved hole and extends into the collection groove 10. The collection box 11 is used to collect the tablet residues that fall into the collection groove 10. In addition, the collection box 11 is slidably connected in a rail manner, and the collected tablet residues can be poured out by sliding the collection box 11 out of the base 1.

[0034] Among them, as Figure 3 shown, a slider 92 is installed at one end of the connecting rod 91 away from the magnet 93. The slider 92 can be fixed to the end of the connecting rod 91 by welding. A pair of sliding grooves 13 are provided on the outer periphery of the push rod 5. The slider 92 is slidably connected to the sliding grooves 13. When detecting the tablets, the push rod 5 moves vertically downward. First, the magnet 93 can abut against the magnetic member 67. As the push rod 5 continues to descend, the slider 92 at one end of the connecting rod 91 can slide in the sliding grooves 13, thereby ensuring the normal progress of the detection work.

[0035] In addition, as Figure 2 shown, an installation groove is provided on the top of the base 1, and a rubber pad 12 is installed in the installation groove. The rubber pad 12 abuts against the bottom of the bearing plate 61. By providing the rubber pad 12, a buffering effect can be achieved on the reset action of the bearing plate 61.

[0036] Working principle:

[0037] By placing the tablet to be detected in the placement groove 63 on the top of the bearing plate 61, at this time, by starting the hydraulic cylinder 4 to control the push rod 5 to move downward, the pressure sensor 7 and the pressure head 8 are moved downward to the tablet surface and pressure is applied. The pressure sensor 7 can detect the pressure value of the pressure head 8, so as to detect the tablet hardness by monitoring the degree of pressure in real time. At the same time, the magnet 93 can be adsorbed to the magnetic part 67. After the detection is completed, the hydraulic cylinder 4 can be used to control the push rod 5 to move upward. Since the magnet 93 and the magnetic part 67 are adsorbed to each other, the magnet 93 can drive the limiting block 66 on one side of the magnetic part 67 to slide in the limiting groove 65, so as to realize the rotation of the bearing plate 61, causing the bearing plate 61 to tilt. The broken tablet residues in the placement groove 63 can be discharged into the collection groove 10 through the discharge port 64 under the guidance of the inclined surface, so as to achieve the purpose of automatically collecting the tablet residues. Until the limiting block 66 slides to the highest position, the magnet 93 and the magnetic part 67 are separated, and the bearing plate 61 automatically resets under the action of gravity, preparing for the next test.

[0038] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
