It precisely applies force and controls displacement through a force application device and a displacement device, sensors collect force and displacement data, the control system coordinates the operation of each component, and the data processing system analyzes the data and outputs the results.

[0004] In existing technologies, electronic screens that process data accumulate a lot of dust after frequent use. This dust accumulation can lead to blurry screen displays, color distortion, and affect visual effects. Dust can also clog ventilation openings, causing poor heat dissipation, increased temperature, and shortened lifespan of electronic components. Long-term dust accumulation can also cause circuit failures. Therefore, an automatic tear-strength tester for pharmaceutical packaging is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 3This utility model provides an embodiment of an automatic tear-strength tester for pharmaceutical packaging, comprising a base plate 1 and a mounting frame 3. Multiple slide rails 7 are formed on the inner wall of the mounting frame 3. A spring 8 is fixedly connected to the inner wall of each slide rail 7, fixing one end of the spring 8 in a fixed position. A movable shaft 6 is fixedly connected to the other end of the spring 8, and the positional change of the movable shaft 6 causes the spring 8 to deform. A cleaning plate 5 is fixedly connected to the other end of each movable shaft 6, and the positional change of the cleaning plate 5 causes the multiple movable shafts 6 to move. The cleaning plate 5 is slidably connected to the inner wall of the mounting frame 3, allowing the cleaning plate 5 to directly clean the inner wall of the mounting frame 3.

[0033] The inner wall of the mounting frame 3 has a limiting component to define the cleaning path. This limiting component includes a handle, which is fixedly connected to the top of the cleaning plate 5, allowing the cleaning plate 5 to move accordingly with the change in the handle's position. A groove 4 is provided on the inner wall of the mounting frame 3 to limit the movement of the cleaning structure. The handle is externally slidably connected to the inner wall of the groove 4, allowing it to move along the groove 4. The movable shaft 6 is externally slidably connected to the inner wall of the slide rail 7, which limits the movement of the movable shaft 6. A processing table 2 is fixedly connected to the top of the base plate 1, and the bottom of the mounting frame 3 is mounted on top of the processing table 2, providing support for the position of the mounting frame 3.

[0034] Reference Figure 2 and Figure 4 A test assembly for tear strength testing is fixedly connected to the top of the substrate 1. The test assembly includes two fixing boxes 11, and a test platform 9 is fixedly connected to the top of the substrate 1 for tear strength testing. A lifting channel 10 is formed on the inner wall of the test platform 9. The outer side of the fixing box 11 is fixedly connected to the inner wall of the lifting channel 10, allowing one end of the object to be fixed in position. The outer side of the other fixing box 11 is slidably connected to the inner wall of the lifting channel 10, allowing one end of the object fixed in the other fixing box 11 to move in position along the inner wall of the lifting channel 10. A motor 12 is installed on the inner wall of the lifting channel 10, serving to fix the motor 12 in a fixed position. A rotating block 13 is fixedly connected to the drive end of the motor 12. When the motor 12 is started, the rotation of the drive end of the motor 12 drives the rotating block 13 to rotate. The outer surface of the rotating block 13 is uneven, and its rotation compresses the space on both sides.

[0035] Two movable rods 14 are rotatably connected to the inner wall of the fixed box 11. The outer side of the rotating block 13 contacts the outer side of the two movable rods 14, so that when the rotating block 13 rotates, it can press the two movable rods 14 to change their position. A clamping block 15 is fixedly connected to the outer side of the movable rods 14. The position change of the movable rods 14 causes the clamping block 15 to change its position. Multiple friction blocks 16 are fixedly connected to the outer side of the clamping block 15. The position change of the clamping block 15 causes the multiple friction blocks 16 to change their position. The friction blocks 16 can increase the friction between the clamping block 15 and the object, making it easier to fix the object in position. A second spring 17 is fixedly connected to the outer side of the movable rods 14. The position change of the movable rods 14 can cause the second spring 17 to deform. The other end of the two second springs 17 is fixedly connected to the inner wall of the fixed box 11. The fixed box 11 has the function of fixing one end of the second spring 17 in position, so that the second spring 17 can be smoothly reset later.

[0036] Working principle: The traction handle allows the cleaning plate 5 to slide along the inner wall of the slide groove 4, thus enabling the cleaning plate 5 to move along a designated position to clean the electronic screen. The positional movement of the cleaning plate 5 also causes multiple moving shafts 6 to move, resulting in the deformation of spring 8. After the external force is removed, the return of spring 8 drives the moving shafts 6 to move, allowing the cleaning plate 5 to return to its original position, preparing for the next cleaning cycle. Timely cleaning of the electronic screen removes dust, ensuring clear display, accurate colors, and improved visual effects. It also maintains good ventilation, prevents component overheating, and extends lifespan. Furthermore, it avoids circuit failures caused by dust, ensuring stable equipment operation and efficient and smooth data processing.

[0037] The two ends of the object to be tested are placed on opposite sides of the two clamping blocks 15. The two motors 12 are started, causing the position of the drive end of the motors 12 to change, which drives the rotating block 13 to rotate. The rotating block 13 exerts a lateral squeezing effect on the two moving rods 14, so that the moving rods 14 can rotate along the center position. This causes the other ends of the two moving rods 14 to drive the two clamping blocks 15 to move closer together, pressing the object tightly. This is more convenient than manual adjustment. In addition, the addition of multiple friction blocks 16 can increase the friction force on the object, so that the object will not easily detach from the structure. The clamping force at both ends of the tear force test can be adjusted in time to ensure that the packaging material is subjected to a uniform and stable force during the test, making the test results more accurate and reliable. It avoids material slippage or damage caused by improper clamping force adjustment by manual adjustment, improves test efficiency and accuracy, and ensures the effectiveness of drug packaging quality testing.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
