Technical Field

[0001] The utility model relates to the field of tablet hardness testers, in particular to a hardness testing device for drug production and processing. Background Art

[0002] Tablet hardness tester is a key equipment to ensure the quality of drugs. It can accurately evaluate the hardness and friability of tablets through high-precision measurement and intelligent operation. This instrument is not only easy to operate and accurate in testing, but also has multi-functional integration, providing strong technical support for pharmaceutical companies in the development of new drugs, process optimization and quality control. By using tablet hardness tester, pharmaceutical companies can better control the quality of tablets, ensure that their appearance meets the requirements and is not easy to be brittle, thereby improving the stability and bioavailability of drugs. This instrument plays an indispensable role in drug production and provides a solid guarantee for the quality and safety of drugs.

[0003] Existing tablet hardness testers face an operational challenge when testing the hardness of multiple tablets. Specifically, traditional testers are equipped with a cover on the outside of the test platform to prevent tablet fragments from splashing after being broken. However, when a large number of tablets need to be tested, testers must frequently open and close the cover, which not only affects the convenience of the tablet hardness tester, but also significantly reduces the detection efficiency of tablets. Therefore, this design is not efficient enough in actual applications and needs to be further optimized to improve user experience and work efficiency. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a hardness testing device for drug production and processing, so as to solve the technical problem that when a large number of tablets are tested, the cover plate needs to be frequently opened and closed, which reduces the convenience of using the tablet hardness tester.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hardness testing device for drug production and processing, comprising a device body, a mounting groove is provided on the surface of the device body, a cover plate is rotatably connected to one side of the mounting groove, a discharge mechanism is arranged on the cover plate, the discharge mechanism comprises a movable sleeve, mounting ears are arranged on both sides of the movable sleeve, a spring telescopic rod is arranged between the bottom end of the mounting ear and the cover plate, a partition is arranged on the inner side of the movable sleeve, a valve is arranged on the inner side of the partition, the valve is connected to an external air compressor through a connecting pipe, and a control switch is arranged on one side of the top of the device body.

[0006] By adopting the above technical solution, when using, the operator only needs to press the movable sleeve in the discharge mechanism to quickly release the tablets, which will drop directly onto the receiving plate. During this process, there is no need to frequently open the cover plate, which greatly simplifies the operation steps and saves operation time.

[0007] Further, a funnel is provided at the top of the movable sleeve for receiving and placing tablets.

[0008] By adopting the above technical solution, the funnel can conveniently receive and place tablets. Since the funnel has a relatively large opening, the operator can easily put the tablets into the movable sleeve without special alignment when placing the tablets, which greatly improves the convenience of putting tablets.

[0009] Further, the spring telescopic rod is used to provide elastic resetability for the movable sleeve.

[0010] By adopting the above technical solution, the spring telescopic rod provides stable elastic resetability for the movable sleeve, which enables the movable sleeve to automatically reset to the initial position after each tablet is put in, without manual adjustment by the operator.

[0011] Further, the partition plate is in a curved arc plate structure, and an opening is formed between the bottom end and the inner wall of the movable sleeve.

[0012] By adopting the above technical solution, the tablets can smoothly slide down along the curved arc surface when passing through the partition plate, effectively avoiding jamming or blocking of the tablets during the putting process.

[0013] Further, the valve is electrically connected to an external power supply through a control switch.

[0014] By adopting the above technical solution, electrical control of the valve switch is realized, which makes the operation more convenient and accurate. The operator can easily control the opening and closing of the valve only through the control switch without manually operating the valve, improving work efficiency.

[0015] Further, a receiving plate is arranged inside the installation groove. One side of the top of the receiving plate is provided with a fixing plate, and the other side of the top of the receiving plate is provided with a clamping plate.

[0016] By adopting the above technical solution, the receiving plate provides a stable platform for receiving the tablets falling from the movable sleeve, ensuring the stable position of the tablets during the test.

[0017] Further, a receiving frame is arranged below the receiving plate for collecting tablet debris, and a control panel is arranged on the other side of the top of the device body.

[0018] By adopting the above technical solution, the receiving frame can effectively collect the debris generated by the tablets during the test, keep the test environment clean, and prevent the debris from interfering with the test results or polluting the equipment.

[0019] In summary, the main beneficial effects of the present utility model are as follows:

[0020] In the present utility model, through the feeding mechanism, the user first presses the movable sleeve, causing it to move downward against the elastic force of the spring telescopic rod until it contacts the receiving plate. Subsequently, the tablet to be tested is put into the movable sleeve through the funnel. The tablet falls onto the receiving plate due to its own weight. After completing this step, the user only needs to release the movable sleeve, and the spring telescopic rod will use its elastic force to reset the movable sleeve, thus avoiding interfering with the detection process. After the detection of a single tablet is completed, the user presses the control switch to open the valve inside the partition. At this time, the external air compressor performs high-pressure flushing on the surface of the receiving plate through the connecting pipe, effectively removing the residue of the broken tablets and ensuring the accuracy of the next detection. This not only avoids the cumbersome operation of frequently opening the cover plate in the traditional test but also completes the rapid feeding of the tablets by simply pressing the movable sleeve, significantly improving the convenience of use and the detection efficiency of the tablet hardness tester.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0027] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model. Embodiment 1:

[0028] A hardness testing device for pharmaceutical production and processing, as Figures 1 - 4As shown in the figure, it includes a device main body 1. An installation groove 3 is provided on the surface of the device main body 1. One side of the installation groove 3 is rotatably connected with a cover plate 5. A feeding mechanism 6 is arranged on the cover plate 5. The feeding mechanism 6 includes a movable sleeve 601. Installation ears 603 are arranged on both sides of the movable sleeve 601. A spring telescopic rod 604 is arranged between the bottom end of the installation ear 603 and the cover plate 5. A partition 605 is arranged inside the movable sleeve 601. A valve 606 is arranged inside the partition 605. The valve 606 is connected to an external air compressor through a connecting pipe 607. A control switch 7 is arranged on one side of the top of the device main body 1. When an operator uses it, only by pressing the movable sleeve 601 in the feeding mechanism 6 can the rapid feeding of tablets be realized, and the tablets directly fall onto the receiving plate 401. In this process, there is no need to frequently open the cover plate 5, which greatly simplifies the operation steps and saves operation time. At the same time, the spring telescopic rod 604 in the device provides a stable reset function for the movable sleeve 601, ensuring that it can accurately reset after each feeding to prepare for the next feeding. In addition, the device is also equipped with a high-pressure flushing system, including the valve 606 and the connecting pipe 607, which can automatically clean the receiving plate 401 after each test to ensure the cleanliness of the test environment, thereby improving the accuracy of the test.

[0029] Refer to Figure 3 、 Figure 4 , a funnel 602 is arranged on the top of the movable sleeve 601 for receiving and placing tablets. The funnel 602 can conveniently receive and place tablets. Due to the large opening of the funnel 602, when an operator places tablets, there is no need to specifically align them, and the tablets can be easily put into the movable sleeve 601. This greatly improves the convenience of feeding tablets. At the same time, the funnel 602 can also play a guiding role to ensure that the tablets can accurately fall into the movable sleeve 601 and slide down along the inclined surface of the funnel onto the receiving plate 401 for hardness testing, reducing the loss and waste of tablets during the feeding process, and ensuring the coherence and accuracy of the test.

[0030] Refer to Figure 3 、 Figure 4 , the spring telescopic rod 604 is used to provide elastic reset for the movable sleeve 601. The spring telescopic rod 604 provides stable elastic reset for the movable sleeve 601. This enables the movable sleeve 601 to automatically reset to the initial position after each feeding of tablets without manual adjustment by the operator. At the same time, the elastic force of the spring telescopic rod 604 ensures the smoothness and accuracy of the movable sleeve 601 during the reset process, avoiding equipment damage or test errors caused by improper manual operation. It not only simplifies the operation steps, improves work efficiency, but also enhances the stability and reliability of the test.

[0031] Refer to Figure 3 、 Figure 4, the partition plate 605 is in the structure of a curved arc plate, and there is an opening formed between the bottom end and the inner wall of the movable sleeve 601, so that the tablets can slide smoothly along the curved arc surface when passing through the partition plate 605, effectively avoiding jamming or blocking of the tablets during the feeding process. At the same time, the opening formed between the bottom end of the partition plate 605 and the inner wall of the movable sleeve 601 ensures that the tablets can smoothly slide from the partition plate 605 onto the receiving plate 401 for subsequent hardness testing, improving the smoothness of tablet feeding and the testing efficiency, reducing the intervention of the operator during the tablet feeding process, and further optimizing the usability of the tablet hardness tester.

[0032] Refer to Figure 1 , Figure 2 , Figure 4 , the valve 606 is electrically connected to an external power supply through a control switch 7, realizing the electrical control of the valve switch. This makes the operation more convenient and precise. The operator can easily control the opening and closing of the valve 606 only through the control switch 7 without manually operating the valve, improving the work efficiency. At the same time, the electrical connection method also enhances the safety and reliability of the equipment. Since the control switch 7 is connected to the external power supply, an electrical protection device can be set to ensure the safety of the operation process and prevent accidents. The electrical control can also achieve precise control of the opening and closing of the valve, avoiding errors and instabilities that may be brought by manual operation. Embodiment 2:

[0033] Refer to Figure 1 , Figure 2 , Figure 4 , a receiving plate 401 is arranged inside the installation groove 3. On one side of the top of the receiving plate 401, a fixing plate 402 is arranged, and on the other side of the top of the receiving plate 401, a clamping plate 403 is arranged. The receiving plate 401 provides a stable platform for receiving the tablets falling from the movable sleeve 601, ensuring the stable position of the tablets during the testing process. At the same time, the fixing plate 402 on one side of the top of the receiving plate 401 and the clamping plate 403 on the other side work together to fix the tablets to be tested, preventing them from moving or tilting during the testing process, thereby ensuring the accuracy of the test results, not only simplifying the preparation work before the test, but also improving the reliability and repeatability of the test.

[0034] Refer to Figure 1 , Figure 2 , Figure 4, a receiving frame 404 is provided below the receiving plate 401 for collecting tablet debris. On the other side of the top of the device main body 1, a control panel 2 is provided. The receiving frame 404 can effectively collect the debris generated during the tablet test, keep the test environment clean, prevent the debris from interfering with the test results or contaminating the equipment. At the same time, the control panel 2 provided on the other side of the top of the device main body 1 enables the operator to conveniently control and monitor the test process, including starting the test, adjusting the test parameters, and viewing the test results, etc., greatly improving the operability and convenience of use of the equipment.

[0035] The implementation principle of the present utility model is as follows: First, press the movable sleeve 601, causing the movable sleeve 601 to move downward against the elastic force of the spring telescopic rod 604 on one side, so that the bottom end of the movable sleeve 601 abuts against the top surface of the receiving plate 401. Then, place the tablet to be tested into the interior of the movable sleeve 601 from the funnel 602. At this time, due to the factor of its own weight, the tablet falls onto the top of the receiving plate 401. Then, release the pressing force on the movable sleeve 601, and utilize the elastic force of the spring telescopic rod 604 to cause the movable sleeve 601 to move upward for resetting, so as to avoid the bottom end of the movable sleeve 601 affecting the implementation of the detection process. When the detection of a single tablet is completed, press the control switch 7, causing the valve 606 inside the partition plate 605 to open. At this time, use an external air compressor and conduct high-pressure flushing on the surface of the receiving plate 401 through the connecting pipe 607 to avoid the influence of the broken tablet on the next tablet detection, and complete the detection process of a single tablet. During this implementation process, it is beneficial to avoid the operation of frequently opening the cover plate 5 in the traditional process. Only by pressing the movable sleeve 601 can the tablet feeding work be completed, thereby improving the convenience of use of the tablet hardness tester.

[0036] Parts not involved in the present utility model are the same as or can be implemented using the prior art, and will not be elaborated here too much.
