Description

Technical Field

[0001] This utility model relates to the field of granulation technology, specifically to a particle quality inspection device for a dry granulation system. Background Technology

[0002] Dry granulation is a process in which drugs are mixed with diluents, disintegrants, lubricants and other powders, then processed 1-3 times by rolling or open rubber mixing mills to form thin sheets of the required hardness, and then crushed into granules by a swing granulator. It is widely used in pharmaceutical, food and chemical industries.

[0003] The particle quality inspection equipment of a dry granulation system is a type of testing equipment used to inspect various aspects of the quality of particles produced by the dry granulation system. For example, it includes laser particle size analyzers used to detect particle size to avoid particles that are too coarse or too fine, which could affect subsequent processing; and particle hardness measuring instruments used to detect particle hardness to assess the particles' resistance to breakage and ensure that they will not break due to external forces during subsequent processing, transportation, and use, thus affecting product quality. These testing devices used to detect particle quality can be referred to as particle quality inspection equipment for a dry granulation system.

[0004] However, after using a particle hardness tester to test the hardness of particles, the location of broken particles may be affected by the physical properties of the raw materials, such as viscosity or solubility, resulting in white marks adhering to the particle's placement location. These white marks may affect the stress on the particles during subsequent tests, thus impacting the test results. To ensure the accuracy of the next test results, the white marks need to be cleaned, which affects the equipment's testing efficiency. Therefore, this does not meet the existing requirements. To address this, we propose a particle quality inspection device for a dry granulation system. Utility Model Content

These white marks may affect the stress on the particles in the next test, thus affecting the test results. In order to ensure the accuracy of the next test results, it is necessary to clean the white marks, which affects the testing efficiency of the equipment.

The retaining plate is provided with a spring groove inside. The spring groove contains a first spring. A metal ring located inside the spring groove is connected to the front end face of the first first spring and the rear end face of the second first spring from left to right. The two metal rings are respectively fixedly sleeved on the outer surfaces of the two connecting rods.

[0008] Both of the card plates have arc-shaped fixing grooves on their opposite surfaces, and a positioning groove is provided between the two arc-shaped fixing grooves. A particle placement bowl is placed inside the positioning groove, and an annular fixing groove is provided on the lower side of the outer surface of the particle placement bowl.

[0015] This invention relates to a method for testing the hardness of particles. When particles need to be tested using equipment, the particles are placed inside a particle holding bowl. A single-cylinder pushes a hardness testing probe to measure the hardness of the particles inside the bowl. During this process, the single-cylinder pushes two clamping plates inward simultaneously to secure the particle holding bowl. Once the testing is complete and the hardness testing probe returns to its original position, the bowl is released. If white marks are found inside the particle holding bowl due to broken particles, the bowl can be easily removed and replaced. This technical solution allows for quick replacement of the particle holding bowl if white marks appear, preventing the testing efficiency from being affected by these marks.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] The particle hardness inspection bench 1 (model GYJ-30C), single-cylinder cylinder 6 (model SC-32), and first spring 16 (model JX110) mentioned in this utility model can all be obtained from the market or through private customization.

[0022] Please see Figures 1 to 3An embodiment of this utility model provides a particle quality inspection device for a dry granulation system, including a particle hardness inspection table 1. A single-cylinder cylinder 6 is fixedly installed on the upper side inside the particle hardness inspection table 1. The piston rod of the single-cylinder cylinder 6 is connected to a lower pressure plate 7. A push rod 9 is fixedly provided on both sides of the lower end face of the lower pressure plate 7. The lower end face of the push rod 9 is an inclined surface 10. A rectangular push block 11 is provided below the inclined surface 10. A second spring 19 is connected to the opposite face of the two rectangular push blocks 11.

[0023] The lower end face of the rectangular push block 11 is fixed with a metal rod 12 that is slidably connected to the inside of the particle hardness inspection table 1. A connecting rod 18 is fixedly provided on the opposite face of the two metal rods 12. A locking plate 13 is provided on the outer side of the rear end of the first connecting rod 18 and the outer side of the front end of the second connecting rod 18 from left to right. A spring groove 15 is provided inside the locking plate 13. A first spring 16 is contained inside the spring groove 15. A metal ring 17 located inside the spring groove 15 is connected to the front end face of the first first spring 16 and the rear end face of the second first spring 16 from left to right. The two metal rings 17 are respectively fixedly sleeved on the outer surface of the two connecting rods 18.

[0024] Both of the two card plates 13 have arc-shaped fixing grooves 14 on their opposite sides. A positioning groove 4 is provided between the two arc-shaped fixing grooves 14. A particle placement bowl 3 is placed inside the positioning groove 4. An annular fixing groove 5 is provided on the lower side of the outer surface of the particle placement bowl 3, and the position of the annular fixing groove 5 corresponds to the position of the arc-shaped fixing groove 14.

[0025] A hardness testing probe 8 is fixedly installed at the middle position of the lower end face of the lower pressure plate 7, and the lower pressure plate 7 and the hardness testing probe 8 are fixed together by screws; a control panel 2 is fixedly installed on one side of the outer surface of the particle hardness inspection table 1, and the hardness testing probe 8 and the single-cylinder cylinder 6 are electrically connected to the control panel 2; the hardness testing probe 8 and the single-cylinder cylinder 6 can be controlled through the control panel 2.

[0026] When it is necessary to test the hardness of the particles using the equipment, the particles are placed inside the particle placement bowl 3. Then, the lower pressure plate 7 connected to it is pushed down by the single-cylinder cylinder 6. As the lower pressure plate 7 moves downward, the hardness testing probe 8 fixed to the lower end face of the lower pressure plate 7 will also move downward. When the hardness testing probe 8 contacts the particles inside the particle placement bowl 3, the hardness of the particles can be tested as the hardness testing probe 8 descends, and the test result is displayed on the control panel 2.

[0027] When the pressure plate 7 is pushed downward, the push rod 9 fixed to it will move downward together. As the push rod 9 descends, the inclined surface 10 on the lower end face of the push rod 9 will contact the rectangular push block 11. Under the push of the inclined surface 10, as the push rod 9 descends, the rectangular push block 11 will move inward. During the inward movement of the rectangular push block 11, the metal rod 12 fixed to the lower end face of the rectangular push block 11 and the clamping plate 13 connected to the metal rod 12 will move inward together. As the clamping plate 13 moves, the end of the arc-shaped fixing groove 14 on the outer surface of the clamping plate 13 will be locked into the annular fixing groove 5 on the outer surface of the particle placement bowl 3, thereby fixing the particle placement bowl 3. By fixing the particle placement bowl 3, it can be prevented that when the particles inside the particle placement bowl 3 are not in the middle position inside the particle placement bowl 3, the particle placement bowl 3 may be subjected to excessive downward pressure on one side, which may cause the particle placement bowl 3 to tilt.

[0028] When the rectangular push block 11 is pushed inward, it will compress the second spring 19 connected to it. After the hardness test of the particles is completed, the lower pressure plate 7, hardness test probe 8 and push rod 9 are pulled back to their original positions by the single-cylinder cylinder 6. With the movement of the push rod 9 and the reaction force of the compressed second spring 19, the rectangular push block 11 and the card plate 13 indirectly connected to it can be pushed back to their original positions, thereby releasing the fixation of the particle placement bowl 3. If there are white marks inside the particle placement bowl 3 due to broken particles, the particle placement bowl 3 can be removed and replaced directly. With the above technical solution, if white marks are produced inside the particle placement bowl 3 used to store particles, it can be quickly replaced, thereby preventing the detection efficiency of the equipment from being affected by white marks.

[0029] When the clamping plate 13 is already inserted into the annular fixing groove 5 on the outer surface of the particle placement bowl 3 and cannot move further inward, but the hardness testing probe 8 has not yet contacted the particle due to its small size, as the metal rod 12 moves, the metal ring 17 connected to it via the connecting rod 18 will penetrate into the spring groove 15 and compress the first spring 16. This structure can prevent the hardness testing probe 8 from being unable to move further downward because the clamping plate 13 is already inserted into the annular fixing groove 5.

[0030] The metal rod 12 is a square column, and the lower end face of the metal rod 12 is slidably connected to the interior of the particle hardness inspection table 1. This structure can prevent the metal rod 12 from rotating, which would cause the position of the rectangular push block 11 to change and prevent the downward-moving inclined surface 10 from contacting the rectangular push block 11.

[0031] The outer surface of the bottom end of the particle placement bowl 3 is in contact with the inner wall of the positioning groove 4, and the particle placement bowl 3 and the positioning groove 4 are slidably connected; this structure can prevent the particle placement bowl 3 from shaking.

[0032] A protective cover plate is provided above the single-cylinder cylinder 6 on the outer surface of the particle hardness inspection table 1, and the particle hardness inspection table 1 and the protective cover plate are fixed together by screws; the protective cover plate can protect the internal structure of the particle hardness inspection table 1, and when the internal structure of the particle hardness inspection table 1 fails, the protective cover plate can be removed to repair the internal structure of the particle hardness inspection table 1.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
