Description

Technical Field

[0001] This utility model relates to the field of membrane testing equipment, and in particular to a testing device for antibacterial PE wrapping film. Background Technology

[0002] After the antibacterial PE stretch film is manufactured, its quality must be strictly tested. Among them, the tensile properties and puncture resistance of the film are two key test indicators.

[0003] In the tensile strength testing stage, a specialized tensile testing machine is required. During operation, the clamping components of the testing machine are used to firmly hold both ends of the stretch film. Then, the power unit is activated to stretch the film. Throughout this process, the testing element collects relevant data in real time and transmits it to a supporting computer system for analysis and processing, ultimately presenting a clear and intuitive test result.

[0004] The puncture resistance test involves fixing the stretch film within a ring-shaped fixing device. Then, a probe at the top of the device applies puncture pressure to the film inside the ring, thus completing the test. Similarly, the data generated during the test is transmitted to a computer, processed, and the final result is output.

[0005] Therefore, it is evident that at least two different types of equipment are required for inspecting stretch film, and the operations must be carried out separately. In other words, after completing one type of inspection, a new sample must be taken before another inspection can be conducted. This separate operation method is not only time-consuming and labor-intensive, but also requires companies to purchase at least two types of equipment, which undoubtedly significantly increases costs.

[0018] According to one embodiment of the present invention, in conjunction with Figures 1-6 As shown.

[0019] An antibacterial PE stretch film testing device includes: a testing platform 1, which is composed of a base and a hollow vertical plate welded together. Two symmetrical grooves 2 are formed on one side of the vertical plate of the testing platform 1. The device also includes two sliders 3, each sliding along one of the grooves 2, installed inside the grooves 2. A gear 7 is rotatably mounted inside the testing platform 1. A power assembly 6 is also installed on one side of the testing platform 1 to drive the gear 7. A first rack 8 and a second rack 9, meshing with the gear 7, are also installed inside the testing platform 1. The first rack 8 and the second rack 9 are located on opposite sides of the gear 7, and one side of each rack 8 and the other rack 9 are welded and fixed to the two sliders 3 to drive the sliders 3. The height of the first rack 8 is higher than the height of the second rack 9. Testing mechanisms are installed on one side of each slider 3, namely a first testing mechanism for detecting puncture resistance and a second testing mechanism for detecting tensile strength. The rotation of gear 7 drives the first rack 8 and the second rack 9 to move, which in turn drives the two sliders 3 to move in opposite directions inside the slide groove 2. One slider 3 drives the first detection mechanism to perform puncture detection, and the other slider 3 drives the second detection mechanism to perform tensile detection.

[0020] Specifically, power component 6 is a stepper motor with a self-locking shaft function.

[0021] In this embodiment, the first detection mechanism includes a first detection element 4 for detecting puncture data, and also includes a first ring 10 welded and fixed to one side of the detection table 1. A second ring 11 is connected to the top of the first ring 10 through a connecting part. The membrane is squeezed and fixed by the cooperation of the first ring 10 and the second ring 11, and a puncture detection area is formed in the central region of the first ring 10 and the second ring 11.

[0022] Specifically, the connecting part includes a first extension block 12 symmetrically welded and fixed on both sides of the first ring 10, and a second extension block 18 symmetrically welded and fixed on both sides of the second ring 11. A first screw 13 is welded and fixed to the top of the first extension block 12. The first screw 13 movably passes through the second extension block 18. A compression ring 14 for compressing the second extension block 18 is screwed and rotated at the top of the first screw 13. By compressing with the compression ring 14, the first ring 10 and the second ring 11 are tightly fitted together, thereby compressing and fixing the membrane between the first ring 10 and the second ring 11.

[0023] In this embodiment, the second detection mechanism includes a second detection element 5 for detecting tensile data, and a clamping part for clamping the film installed at the bottom of the second detection element 5.

[0024] Specifically, the clamping part includes a U-shaped block 15 fixed to the bottom of the second detection element 5 by bolts, a clamping plate 17 that is slidably installed on the inner side of the U-shaped block 15 to clamp and fix the film in cooperation with the inner side wall of the U-shaped block 15, and a second screw 16 that moves the clamping plate 17. The second screw 16 passes through the U-shaped block 15 by threads, and one side of the second screw 16 is rotatably mounted on the clamping plate 17. A rotating block for rotating the second screw 16 is welded and fixed on one side of the second screw 16.

[0025] Working principle: Before use, the two sliders 3 are in the same horizontal plane. The membrane to be tested is covered on the top of the first ring 10, and one side of the membrane can extend a bit towards the position of the second detection element 5 (the existing detection element). Then, the second ring 11 is covered on the top of the first ring 10, and the second extension block 18 is fitted on the outside of the first screw 13. Then, the extrusion ring 14 is threaded onto the top of the first screw 13. Then, the extrusion ring 14 is rotated, so that the extrusion ring 14 moves downward along the first screw 13, extruding the second extension block 18, so that the first ring 10 and the second ring 11 fit tightly together, and the membrane to be tested is fixed between the first ring 10 and the second ring 11. The center position of the first ring 10 and the second ring 11 is the puncture detection position. Then, the extended section of the membrane to be tested is moved upward into the U-shaped block 15. Then, the second screw 16 is rotated to drive the clamping plate 17 to move along the inside of the U-shaped block 15 until it cooperates with the inner wall of the U-shaped block 15 to clamp and fix the membrane. At this time, the fixing of the membrane to be tested is completed. The power assembly 6 drives the gear 7 to rotate, which in turn moves the first rack 8 downward. This moves the first detection element 4 (the existing detection element) through the corresponding slider 3. As a result, the detection end of the first detection element 4 presses against the membrane to be tested at the detection point, thus performing a puncture test. At the same time, the second rack 9 moves upward, which moves the second detection element 5 through the corresponding slider 3, causing the clamping part to stretch the membrane. Thus, the stretching degree of the membrane is detected by the second detection element 5. After the test is completed, reset the device, and then remove the membrane after the test.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
