Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment, specifically to a device for testing the hardness of selenium tablets. Background Technology

[0002] Selenium products (such as selenium tablets and selenium supplements) serve as a supplementary form of selenium and have the following core functions and effects: antioxidant effects, immune regulation, thyroid health, cardiovascular protection, reproductive health, and blood sugar and metabolism regulation. After the production of selenium tablets, a series of tests are required to ensure product quality. One of these tests is the hardness test. The hardness of a tablet refers to its ability to resist breakage by external force. If the hardness is too low, it can easily lead to loose tablets and damage during transportation; if the hardness is too high, it may affect disintegration and drug release. Existing hardness testing devices require manual collection of broken tablets during the testing process. Therefore, it is necessary to design a selenium tablet hardness testing device that can collect broken tablets. Summary of the Invention

[0003] The purpose of this invention is to provide a hardness testing device for selenium tablets, which can collect broken tablets.

[0004] The technical solution adopted is as follows:

[0005] A hardness testing device for selenium tablets includes a base, a worktable at the top of the base, a frame on the base, a telescopic mechanism vertically mounted on the frame corresponding to the worktable, a pressure testing module connected to the lower end of the telescopic mechanism, a controller and a display connected to the pressure testing module on the frame, a lifting frame on the worktable, a protective cover with an opening at the bottom, a through hole at the top of the protective cover corresponding to the telescopic mechanism, a negative pressure dust collection unit on the worktable, and a flexible hose connected to the protective cover.

[0006] Preferably, the telescopic mechanism is an electric push rod.

[0007] Preferably, the lifting frame includes a column, an electric push rod is vertically arranged at the upper end of the column, a crossbeam is connected to the lower end of the electric push rod, and the crossbeam is connected to the protective cover.

[0008] Preferably, the protective cover is made of transparent plastic.

[0009] Preferably, a rubber sealing ring is provided at the lower end of the protective cover.

[0010] Preferably, the negative pressure dust collection unit includes a storage box and a negative pressure fan. The storage box is provided with an inlet and a suction pipe. The inlet is connected to a flexible hose. A filter element is detachably installed at the suction pipe. The suction pipe is connected to the negative pressure fan.

[0011] Compared to existing technologies, the advantages are:

[0012] After the tablets are tested for hardness, the tablets break and produce debris and dust. The negative pressure dust collection unit is activated to use negative pressure to remove the debris and dust from the protective cover, which facilitates the collection of debris and dust.

[0017] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 3 As shown:

[0018] Example 1: A hardness testing device for selenium tablets includes a base 1, a worktable 2 on the upper end of the base 1, a frame 3 on the base 1, a telescopic mechanism 4 vertically arranged on the frame 3 corresponding to the upper and lower ends of the worktable 2, a pressure testing module 5 connected to the lower end of the telescopic mechanism 4, a controller and a display 6 connected to the pressure testing module 5 on the frame 3. During testing, the tablet is placed directly below the pressure testing module 5, the telescopic mechanism 4 extends to control the pressure testing module 5 to press down on the tablet until the tablet breaks, and the pressure reading is displayed on the display 6.

[0019] The workbench 2 is equipped with a lifting frame, which has a protective cover 7 with an opening at the bottom. The upper end of the protective cover 7 has a through hole 8 corresponding to the telescopic mechanism 4. The lifting frame controls the lifting of the protective cover 7, which facilitates the placement of tablets into the protective cover 7. The protective cover 7 confines the tablets inside the protective cover 7, preventing fragments from splashing and dust from being generated during the tablet breakage process.

[0020] The workbench 2 is equipped with a negative pressure dust collection unit, which is connected to the protective cover 7 by a flexible hose 10. The negative pressure draws away the debris and dust inside the protective cover 7, which facilitates the collection of debris and dust.

[0021] Example 2: A hardness testing device for selenium tablets includes a base 1, a worktable 2 on the upper end of the base 1, a frame 3 on the base 1, and a telescopic mechanism 4 vertically mounted on the frame 3 corresponding to the upper and lower ends of the worktable 2. The telescopic mechanism 4 is an electric push rod, and a pressure testing module 5 is connected to the lower end of the telescopic mechanism 4. A controller and a display 6 connected to the pressure testing module 5 are mounted on the frame 3. During testing, the tablet is placed directly below the pressure testing module 5, and the telescopic mechanism 4 extends to control the pressure testing module 5 to press down on the tablet until the tablet breaks. The pressure reading is then displayed on the display 6.

[0022] The workbench 2 is equipped with a lifting frame, which has a protective cover 7 with an opening at the bottom. The protective cover 7 is made of transparent plastic and has a through hole 8 at the top corresponding to the telescopic mechanism 4. The lifting frame includes a column 9, and an electric push rod is vertically installed at the top of the column 9. The lower end of the electric push rod is connected to a crossbeam 14, which is connected to the protective cover 7. The lifting frame controls the lifting and lowering of the protective cover 7, which facilitates the placement of tablets into the protective cover 7. The protective cover 7 confines the tablets inside the protective cover 7, preventing fragments from splashing and dust from being generated during tablet breakage. A rubber sealing ring is installed at the bottom of the protective cover 7, which improves the sealing between the bottom of the protective cover 7 and the workbench 2.

[0023] The workbench 2 is equipped with a negative pressure dust collection unit. The negative pressure dust collection unit is equipped with a flexible hose 10 connected to the protective cover 7. The negative pressure dust collection unit includes a storage box 11 and a negative pressure fan 12. The storage box 11 is equipped with an inlet and a suction pipe 13. The inlet is connected to the flexible hose 10. A filter element is detachably installed at the suction pipe 13. The suction pipe 13 is connected to the negative pressure fan 12. The negative pressure draws away the debris and dust in the protective cover 7, which facilitates the collection of debris and dust.

[0024] The working principle is as follows:

[0025] The lifting frame controls the protective cover 7 to rise, placing the tablet directly below the telescopic mechanism 4. The lifting frame controls the protective cover 7 to lower until it contacts the worktable 2. The telescopic mechanism 4 extends to control the pressure test module 5 to press down the tablet until it breaks. The pressure reading is displayed on the display 6. The fragments and dust generated by the tablet breaking are confined within the protective cover 7. The negative pressure dust extraction unit is activated to use negative pressure to remove the fragments and dust from the protective cover 7.
