Abstract
Description
Technical Field
[0001] The utility model relates to the field of medicine production, in particular to a device for detecting the hardness of medicine tablets. Background Art
[0002] The hardness of pharmaceutical tablets is one of the key indicators of their quality. Tablets with appropriate hardness can remain intact during production, packaging, transportation, and storage, and are not easily broken or worn, thus ensuring the accuracy of drug dosage. If the tablet hardness is too low, it may become loose, seriously affecting the subsequent coating, packaging, and transportation processes. On the other hand, if the tablet hardness is too high, the drug and excipients may be tightly bonded together, making the tablet difficult to disintegrate and the drug ingredients unable to be effectively dissolved, ultimately affecting the efficacy. Through hardness testing, we can understand the impact of factors such as the force applied to the tablet during the tableting process, the degree of bonding between particles, and the amount of excipients added on the tablet hardness. This helps pharmaceutical companies optimize production processes and improve tablet quality and production efficiency.
[0003] In the prior art, after hardness testing of pharmaceutical tablets, a lot of pharmaceutical fragments remain on the testing table of the hardness testing device, which is very inconvenient to clean. Therefore, there is an urgent need for a pharmaceutical tablet hardness testing device that can clean the pharmaceutical fragments remaining on the tray, reduce the workload of operators, and improve work efficiency.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0021] In the description of the present invention, it should be understood that the terms "middle", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0022] In this utility model, unless otherwise specified or limited, the terms "disposed," "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed or detachable connections, mechanical connections, direct connections, or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0023] like Figure 1-4 As shown, a device for testing the hardness of a pharmaceutical tablet comprises a body 1, a fixed block 2 and a telescopic block 3. The body is provided with a groove for a testing platform 9. The tablet is placed on the testing platform. One side of the testing platform is fixedly connected to the body through the fixed block. The fixed block and the testing platform are an integrated structure. A telescopic block for squeezing the tablet is provided on the other side of the testing platform. The telescopic block is slidably connected to the body. The end of the telescopic block away from the body is connected to a driving motor (not shown in the figure) for driving the telescopic block to perform telescopic movement. A purge port 4 is provided on the side of the fixed block close to the testing platform. The purge port is provided at the lower end of the fixed block close to the testing platform. The purge port is connected to an air pipe 5. The air pipe passes through the fixed block from the upper end of the fixed block and is connected to the purge port. The air pipe is connected to an air compressor 6. The air compressor can generate compressed air to The testing platform is purged, and the arrow in the figure indicates the direction of movement of the compressed air. A limit device 8 is provided above the purge port. The limit device is used to limit the tablet to prevent the position of the tablet from shifting during the extrusion process, resulting in deviations in the detected hardness values. The purge port is a rectangular structure, and the air outlet of the purge port is a horizontally arranged rectangular structure. The rectangular structure can evenly purge the testing platform when the air flow comes out, ensuring that the testing platform can be purged clean. Baffles 401 are evenly provided in the rectangular structure. The baffles are used to prevent the tablets from entering the purge port during the detection process, and to keep the tablets evenly stressed to ensure the accuracy of the tablet hardness detection. An electromagnetic valve is provided on the air pipe, which is used to control whether the air pipe is connected, thereby controlling whether the testing platform needs to be purged.
[0024] The limiting device includes two limiting rods 801 arranged on both sides of the detection platform, and a sliding groove is provided on the fixed block, and the two limiting rods are slidably connected in the sliding groove. The two limiting rods slide in the sliding groove. When the tablet is placed on the detection platform, the two limiting rods are slid to limit the tablet to ensure that the tablet will not deviate during the detection process, thereby affecting the detection result. Two adjusting pieces 802 are provided between the two limiting rods, and one end of the two adjusting pieces is fixedly connected to the positioning rod. The two adjusting pieces are symmetrically arranged on both sides of the detection platform, and the ends of the two adjusting pieces away from the detection platform are fixedly connected to the corresponding limiting rods. Bar holes 803 are provided on the two adjusting pieces, and a locking bolt 804 is provided between the two adjusting pieces. The two adjusting pieces are connected by the locking bolt passing through the two bar holes, and the sliding limiting rod is used. When the limiting rod conflicts with the tablet, the locking bolt is passed through the two bar holes in turn. A nut is provided on the locking bolt, and the locking nut is screwed to fix the two adjusting pieces. The two adjusting pieces are arranged above the limit rods to fix the two limit rods so that the tablets can be between the two limit rods. When the tablets are squeezed by the telescopic block, the position will not be offset, thereby ensuring the accuracy of the tablet hardness test results. The two adjusting pieces are arranged above the limit rods. The tablets often break and fly during tablet testing. The two adjusting pieces can also play a role in preventing collapse. A waste box is provided under the testing table, which is slidably connected to the machine body. Most of the tablet fragments after the hardness test will splash up and finally fall into the waste box, and the tablet fragments remaining on the testing table can also fall into the waste box under the purge action of the purge port. The operator only needs to clean the waste box regularly, which effectively improves the detection efficiency. A transparent cover is also provided on the machine table in this device to prevent tablet fragments from splashing during testing. Because the transparent cover is a commonly used technical means in this field, it will not be described here. A pressure sensor is provided on the telescopic block, and the pressure sensor measures the hardness value of the drug tablet.
[0025] Method of using the utility model
[0026] Place the tablet on the testing table, slide the two limit rods so that the inner walls of the two limit rods are in conflict with the tablet. After the position of the limit rod is adjusted, pass the locking bolts through the bar holes of the two limit rods in turn, lock the locking bolts, and thus fix the positions of the two limit rods. Start the drive motor connected to the telescopic block, and the telescopic block begins to move toward the tablet. The telescopic block cooperates with the fixed block to squeeze the tablet, and the hardness value of the tablet is measured by the pressure sensor. After the measurement is completed, the solenoid valve is opened, and the compressed air in the air pipe is transmitted to the purge port to purge the testing table. The tablet fragments on the testing table are blown into the waste box, which saves the operator from cleaning the testing table and improves work efficiency.
