[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] For examples, please refer to Figure 1-6 This utility model provides a technical solution:

[0027] A tablet friability measuring device includes a support frame 1, with a connecting frame 2 fixedly installed at the lower part of the support frame 1. A drive motor 3 is fixedly installed on one side of the connecting frame 2 via a motor mounting frame 31, and a first drive gear 4, a second drive gear 5, a third drive gear 6, a first transmission gear 7, and a second transmission gear 8 are respectively arranged on the other side via shafts 9. The output shafts of the first drive gear 4, the second drive gear 5, and the third drive gear 6 are also fixedly connected to a test cylinder 10. The support frame 1 is installed first, and the connecting frame 2 is fixedly installed at the lower part of its interior. The drive motor 3 is installed on one side of the connecting frame 2 via the motor mounting frame 31, and the first drive gear 4, the second drive gear 5, the third drive gear 6, the first transmission gear 7, and the second transmission gear 8 are sequentially arranged on the other side via shafts 9. Finally, the output shafts of the first drive gear 4, the second drive gear 5, and the third drive gear 6 are fixedly connected to the test cylinder 10.

[0028] Specifically, the output end of the drive motor 3 is keyed to one end of the shaft 9 on the first drive gear 4. The shafts of the second drive gear 5, the third drive gear 6, the first transmission gear 7, and the second transmission gear 8 are connected on the same side through one end of the connecting frame 2 and connected to the bearing 11 located inside the connecting frame 2. The first drive gear 4 and the first transmission gear 7, the first transmission gear 7 and the second drive gear 5, the first drive gear 4 and the second transmission gear 8, and the second transmission gear 8 and the third drive gear 6 are respectively meshed. When the drive motor 3 is started, its output end drives the shaft 9 on the first drive gear 4 to rotate. Because the first drive gear 4 and the first transmission gear 7, the first transmission gear 7 and the second drive gear 5 are meshed... The first drive gear 4 and the second transmission gear 8 are meshed and connected, as are the second transmission gear 8 and the third drive gear 6. The rotation of the first drive gear 4 will drive the other gears to rotate in sequence, so that the first drive gear 4, the second drive gear 5 and the third drive gear 6 rotate synchronously, thereby driving the test cylinder 10 connected to it to rotate stably. This multi-gear transmission structure can realize the efficient transmission and distribution of power, ensuring that the test cylinder 10 rotates smoothly and at a uniform speed, so that the tablets are subjected to a stable and uniform force during the test, improving the accuracy and reliability of the brittleness test results. At the same time, the shafts of each gear are connected by bearings 11 inside the connecting frame 2, which reduces the frictional resistance during rotation, reduces energy consumption, and extends the service life of the equipment.

[0029] The test cylinder 10 has multiple partitions 12 axially installed inside its internal cavity, dividing the interior of the test cylinder 10 into several identical test chambers 13. During the friability test, tablets are placed into each of the respective test chambers 13. The multiple identical test chambers 13 ensure even distribution of the tablets within the test cylinder 10, preventing excessive compression and collisions during rotation. This ensures that each tablet experiences consistent friction and impact forces during testing, thereby improving the accuracy of the test results. Furthermore, the partitioned test chambers 13 facilitate group testing of different batches or types of tablets, improving testing efficiency.

[0030] The test cylinder 10 has a threaded post 14 on its outer periphery away from the connecting frame 2. The outer surface of the threaded post 14 has a threaded groove, and a sealing cap 15 is threadedly connected to it. The sealing cap 15 is threaded to the test cylinder 10 via the threaded groove on the threaded post 14. Before testing, ensure the sealing cap 15 is tightened to complete the seal. This threaded connection between the sealing cap 15 and the test cylinder 10 effectively prevents tablets from being thrown out by the centrifugal force generated by the rotation of the test cylinder 10 during testing, ensuring the integrity of the testing environment. This sealing structure also facilitates opening and closing the test cylinder 10 before and after testing, making it convenient to insert and remove tablets and to clean and maintain the interior of the test cylinder 10.

[0031] Specifically, a detachable miniature vibrator 16 is fixedly installed on the outer surface of the test cylinder 10. The miniature vibrator 16 is equipped with a control button to control its opening and closing. After completing the tablet friability test, the miniature vibrator 16 is activated, causing it to vibrate and dislodge any remaining tablet fragments and powder inside the test cylinder 10. The miniature vibrator 16 greatly simplifies post-test cleaning, quickly and effectively dislodging residual substances for centralized cleaning, saving cleaning time and labor costs, and improving work efficiency. Furthermore, its detachable design allows for easy replacement or repair when needed, increasing the flexibility of equipment use.

[0032] The working process of this utility model is as follows: When using the tablet friability testing device, first open the sealing cover 15, place the tablets to be tested into the respective test chambers 13 inside the test cylinder 10, and then tighten the sealing cover 15. Then start the drive motor 3, whose output end drives the shaft 9 on the first drive gear 4 to rotate. Due to the meshing connection between the gears, the first drive gear 4 sequentially drives the first drive gear 7, the second drive gear 5, the second drive gear 8, and the third drive gear 6 to rotate, thereby making the test cylinder 10 rotate stably. During the rotation, the tablets are subjected to uniform friction and impact forces in the test chambers 13, simulating the stress conditions during actual transportation and storage, and conducting a friability test. After the test is completed, turn off the drive motor 3, press the control button of the micro vibrator 16 to make it vibrate, and shake off the tablet fragments and powder remaining inside the test cylinder 10. Then open the sealing cover 15 and clean the inside of the test cylinder 10. After cleaning, the next test can be performed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
