Description

Technical Field

[0001] The utility model relates to the technical field of tablet hardness detection, in particular to a tablet hardness detection device. Background Art

[0002] Tablets are solid preparations in the form of tablets or special-shaped tablets pressed from a uniform mixture of drugs and excipients. They have many advantages such as accurate dosage, small difference in drug content in tablets, stable quality, easy to take, easy to carry and transport, mechanized production, low cost, etc., and are widely used in the pharmaceutical field.

[0003] As a nutritious ingredient, onion tablets are not only widely used in cooking but also show great potential in the field of health foods. Some weight loss products use high-content and high-activity onion tablets or onion tablet extracts as raw materials to make tablets to help consumers achieve weight loss goals. During the production process of onion tablets, hardness is one of the important indicators to measure the quality of onion tablets. Appropriate hardness can ensure that onion tablets are not easily broken during processing, transportation, and storage, maintaining integrity and aesthetics. By detecting the hardness of onion tablets, defective products that do not meet the requirements can be screened out, ensuring the overall quality of the products and improving consumer satisfaction. During the large-scale production process of onion tablets, a large number of onion tablets need to be subjected to hardness detection. However, in the traditional tablet hardness detection method, after the hardness of a single onion tablet is detected, steps such as slag discharge and re-feeding are required before the hardness detection of the next tablet can be carried out. The hardness detection of tablets is not continuous enough, and the detection efficiency is low, making it difficult to meet the detection requirements for large-scale tablet production. Therefore, this application proposes a tablet hardness detection device to meet the needs. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a tablet hardness detection device, which has the function of continuous hardness detection of tablets, high detection efficiency, and high adaptability.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A tablet hardness detection device includes a detection table; a detection mechanism arranged on the detection table for detecting the hardness of tablets; a tablet storage tube vertically arranged on one side of the detection mechanism for stacking and storing tablets to be detected; a support frame arranged on the detection table for supporting the tablet storage tube and leaving a gap between the bottom end of the tablet storage tube and the detection table that can accommodate a single tablet to move horizontally; a feeding mechanism arranged on the detection table for pushing the lowermost tablet in the tablet storage tube to the detection mechanism.

[0007] Preferably, the detection mechanism includes a frame fixed on the detection table, a hydraulic push rod vertically installed on the frame, and a pressing block installed at the telescopic end of the hydraulic push rod.

[0025] Embodiment

[0026] Please refer to Figures 1 to 5 , the present utility model preferably provides the following technical solution:

[0027] A tablet hardness detection device, including a detection table 1; a detection mechanism 2 arranged on the detection table 1 for detecting the hardness of tablets; a tablet storage tube 3 vertically arranged on one side of the detection mechanism 2 for stacking and storing the tablets to be detected; a support frame 4 arranged on the detection table 1 for supporting the tablet storage tube 3 and leaving a gap between the bottom end of the tablet storage tube 3 and the detection table 1 that can accommodate the horizontal movement of a single tablet; a feeding mechanism 5 arranged on the detection table 1 for pushing the lowermost tablet in the tablet storage tube 3 to the detection mechanism 2. Through this structural method, the tablets to be detected are stacked in the tablet storage tube 3 and are pushed to the detection mechanism 2 by the feeding mechanism 5 for hardness detection. Since the support frame 4 can support the tablet storage tube 3 and leave a gap between the bottom end of the tablet storage tube 3 and the detection table 1 that can accommodate the horizontal movement of a single tablet, continuous hardness detection operation of the tablets can be realized under the continuous pushing of the feeding mechanism 5. In the above technical solution, the described tablets include but are not limited to onion tablets.

[0028] In this embodiment, the detection mechanism 2 includes a frame 21 fixed on the detection table 1, a hydraulic push rod 22 vertically installed on the frame 21, and a pressing block 23 installed at the telescopic end of the hydraulic push rod 22. A pressure sensor 24 is assembled between the telescopic end of the hydraulic push rod 22 and the pressing block 23. After the tablet is pushed under the pressing block 23, the hydraulic push rod 22 is started to push the pressing block 23 downward to apply pressure to the tablet, and the pressure sensor 24 is used to record the pressure when the tablet is compressed, so as to calculate and obtain the hardness of the tablet.

[0029] In this embodiment, the feeding mechanism 5 includes a pushing piece 20 disposed on the side of the tablet storage tube 3 away from the detection mechanism 2. A pushing rod 19 is horizontally fixed to the side of the pushing piece 20 away from the tablet storage tube 3. One end of the pushing rod 19 away from the pushing piece 20 is fixed with a connecting plate 18. A first electric push rod 17 is horizontally fixed to the bottom of the detection table 1. The first electric push rod 17 is arranged in parallel with the pushing rod 19, and the telescopic end of the first electric push rod 17 is fixedly connected to the connecting plate 18. Starting the first electric push rod 17 drives the pushing rod 19 to move towards the lower pressing block 23, and the pushing rod 19 drives the pushing piece 20 to push the tablet at the bottommost end of the tablet storage tube 3 to below the lower pressing block 23 for hardness detection.

[0030] Further, an auxiliary hopper cover 6 is provided at the top end of the tablet storage tube 3 to facilitate the feeding of tablets into the tablet storage tube 3. A through groove 7 is vertically formed on the side wall of the tablet storage tube 3 to facilitate observing the remaining amount of tablets in the tablet storage tube 3.

[0031] Further, a second electric push rod 25 is horizontally installed at the bottom of the frame 21. The telescopic end of the second electric push rod 25 is fixed with a chip removal push plate 26. The bottom of the chip removal push plate 26 is slidably attached to the upper surface of the detection table 1. A chip removal groove 9 is formed on the detection table 1 at a position away from the chip removal push plate 26 of the lower pressing block 23. A recycling box 10 is provided at a position corresponding to the chip removal groove 9 inside the detection table 1. After each tablet is detected, by starting the second electric push rod 25 to drive the chip removal push plate 26 to move, the crushed tablets on the detection table 1 can be pushed to the chip removal groove 9 and fall into the recycling box 10 for collection, reducing the pollution of the detection environment by the crushed tablets, and at the same time facilitating the continuous hardness detection of numerous tablets in the tablet storage tube 3.

[0032] In a further embodiment, a stop block 8 is provided on the detection table 1 at a position away from the tablet storage tube 3 of the lower pressing block 23. The stop block 8 movably penetrates the detection table 1. A U-shaped frame 28 is fixed to the bottom of the detection table 1. A spring 29 is vertically arranged between the bottom of the stop block 8 and the U-shaped frame 28. A guide rod 30 is inserted into the spring 29. The top end of the guide rod 30 is fixedly connected to the stop block 8. The bottom end of the guide rod 30 movably penetrates the U-shaped frame 28. An arc-shaped positioning groove 27 is formed on the side of the stop block 8 facing the lower pressing block 23. During the process of the tablet being pushed by the pushing piece 20 to below the lower pressing block 23, the stop block 8 is used to block and position the tablet. In addition, both sides of the stop block 8 have inclined surfaces. When the second electric push rod 25 pushes the chip removal push plate 26 to move, by using the elastic support of the spring 29 to push the stop block 8, the chip removal push plate 26 can press the stop block 8 into the detection table 1 to facilitate the cleaning and collection of the crushed tablets.

[0033] In this embodiment, the support frame 4 includes a pair of cross arms 11 horizontally fixed on the side wall of the tablet storage tube 3, a sleeve block 12 provided at the ends of the pair of cross arms 11, and a lead screw 13 vertically threaded through the sleeve block 12.

A transmission belt 15 is sleeved on the pair of belt pulleys 14, and a handle 16 is provided at the bottom end of one of the belt pulleys 14. In this structural manner, driven by the belt pulley 14 and the transmission belt 15, turning the handle 16 drives the two lead screws 13 to rotate, and thus the tablet storage tube 3 can be driven to move up and down, adjusting the distance between the bottom end of the tablet storage tube 3 and the test bench 1 to adapt to the continuous hardness detection of tablets with different thicknesses.

[0034] During use, the tablets to be detected are stacked in the tablet storage tube 3. By starting the first electric push rod 17 to drive the push rod 19 to move downward towards the lower pressing block 23, the push rod 19 drives the push piece 20 to push the tablet at the bottommost end of the tablet storage tube 3 below the lower pressing block 23. The stop block 8 can limit and block the tablet. Then, the hydraulic push rod 22 is started to push the lower pressing block 23 downward to apply pressure to the tablet, and the pressure sensor 24 is used to record the pressure when the tablet is compressed, so as to calculate and obtain the hardness of the tablet. In this structural manner, by alternately controlling the expansion and contraction of the first electric push rod 17 and the hydraulic push rod 22, the tablets in the tablet storage tube 3 can be pushed out one by one for hardness detection, improving the hardness detection efficiency of the tablets. In addition, after each tablet is detected, the second electric push rod 25 can be started to drive the chip removal push plate 26 to move, pushing the crushed tablets on the test bench 1 to the chip removal groove 9 and falling into the recycling box 10 for collection, reducing the pollution of the detection environment by the crushed tablets, and at the same time facilitating the continuous hardness detection of many tablets in the tablet storage tube 3. Further, through the cooperation of the two lead screws 13 with the cross arms 11 and the sleeve block 12, the tablet storage tube 3 can be supported in suspension, so that only one tablet can be pushed out by the push piece 20 at the bottom end of the tablet storage tube 3, realizing the one-by-one push hardness detection of multiple tablets in the tablet storage tube 3. And driven by the belt pulley 14 and the transmission belt 15, turning the handle 16 drives the two lead screws 13 to rotate, and thus the tablet storage tube 3 can be driven to move up and down, adjusting the distance between the bottom end of the tablet storage tube 3 and the test bench 1 to adapt to the continuous hardness detection of tablets with different thicknesses, having a high tablet hardness detection efficiency and adaptability.
