Description

Technical Field

[0001] This utility model relates to the field of tablet testing equipment technology, and in particular to a tablet friability tester with adjustable tilt. Background Technology

[0002] In the pharmaceutical industry, tablets are a common drug dosage form. The quality of tablets directly affects the efficacy and safety of drugs. Friability is a key indicator of tablet quality, reflecting the tablet's ability to resist wear and breakage during production, packaging, transportation, and storage. If the friability of tablets does not meet requirements, fragmentation and cracking may occur during these processes. This not only affects the accuracy of drug dosage but may also lead to a decrease in drug stability. Friability testing instruments can simulate these external forces to assess the tablet's wear resistance and friability, thereby ensuring tablet quality. Primarily used in the pharmaceutical industry, it is one of the important pieces of equipment for tablet quality control.

[0003] The testing of tablet fragility often employs a rudimentary method of manual throwing, which fails to account for the influence of factors such as air humidity on tablets, leading to significant measurement errors and failing to meet the demands of modern pharmaceutical tablet production. Therefore, more precise instruments are needed. Currently, traditional tablet fragility testers typically have a fixed structure, placing a certain number of tablets in a cylindrical device and rotating it a certain number of times to detect tablet wear. However, this fixed-structure tester has several problems. It cannot simulate the various tilting conditions that tablets may encounter during actual transportation and storage. In reality, pharmaceutical packaging may be tilted or non-horizontal due to the bumps and jolting of transport vehicles. Traditional testers cannot detect the fragility of tablets under these tilting conditions, resulting in significant discrepancies between experimental data and actual conditions. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tablet friability tester with adjustable tilt, aiming to improve the problem of the inability to tilt in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tiltable tablet friability tester, comprising a housing, a fixed plate fixedly connected to the inner wall of the housing, a motor fixedly connected to the top of the fixed plate, a second rotating shaft rotatably connected to the output end of the motor, a first gear fixedly connected to the top of the second rotating shaft, a second gear meshing with the outer wall of the first gear, a rotating column fixedly connected to the outer wall of the second gear, a rotating chamber fixedly connected to the outer wall of the rotating column, a rotating ring fixedly connected to the front end of the outer wall of the rotating column, a fan blade fixedly connected to the outer wall of the rotating ring, an outer plate fixedly connected to the outer wall of the rotating ring, and an adjustment mechanism fixedly connected to the bottom of the housing for adjusting the angle.

[0006] As a further description of the above technical solution:

[0007] The adjustment mechanism includes a rotating frame, a housing fixedly connected to the top of the rotating frame, a first rotating shaft fixedly connected to one of the two adjacent sides of the rotating frames, a connecting plate fixedly connected to the outer wall of the first rotating shaft, a housing fixedly connected to the outer wall of the connecting plate, a worm gear fixedly connected to the middle of the outer wall of the first rotating shaft, a worm meshing with the outer wall of the worm gear, a drive shaft fixedly connected to the inner wall of the worm, and an opening for movement on the front side of the housing.

[0008] As a further description of the above technical solution:

[0009] A rotating disk is fixedly connected to the front side of the drive shaft, and a handle is fixedly connected to the front side of the rotating disk.

[0010] As a further description of the above technical solution:

[0011] A support plate is fixedly connected to the bottom of the outer shell, and a rivet is fixedly connected to the top of the support plate.

[0012] As a further description of the above technical solution:

[0013] A base plate is fixedly connected to the bottom of the support plate, and an anti-slip pad is fixedly connected to the bottom of the base plate.

[0014] As a further description of the above technical solution:

[0015] A threaded column is fixedly connected to the front side of the outer wall of the rotating column, and a fixing block is slidably connected to the inner wall of the outer plate.

[0016] As a further description of the above technical solution:

[0017] A switch is fixedly connected to the bottom front side of the box, and a display panel is fixedly connected to the front side of the box.

[0018] As a further description of the above technical solution:

[0019] The rear side of the box has ventilation holes, and the top of the box is rotatably connected to a top plate.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when in use, first ensure that the box is placed stably. If the item is tilted, the rotating disc can be rotated by holding the handle. The rotation of the rotating disc will drive the drive shaft to rotate accordingly. Since a worm is installed on the outside of the drive shaft, the worm will also rotate accordingly. The rotation of the worm will further drive the worm wheel to rotate. The rotation of the worm wheel will drive the first rotating shaft to rotate. The two ends of the first rotating shaft are connected to the rotating frame, and the rotating frame is connected to the box, thereby realizing the adjustment of the box.

[0022] 2. In this utility model, the rotating fixing block is opened, then the outer plate is opened, the item to be tested is placed into the rotating chamber, then the outer plate is closed, and the switch is pressed to start the motor. The output end of the motor will drive the second rotating shaft to rotate, and the rotation of the second rotating shaft will cause the first gear to rotate. Since the outer side of the first gear meshes with the second gear, the rotation of the second gear drives the rotating column to rotate, and the rotation of the rotating column in turn causes the rotating chamber to rotate. The inner wall of the rotating chamber is equipped with fan blades, which help to detect the crushing process of the item. Attached Figure Description
