Description

Technical Field

[0001] This utility model relates to the field of PE film testing technology, and more specifically, to a performance testing device for PE film. Background Technology

[0002] Tensile testing (also known as tensile testing) of PE film is a crucial quality inspection item in its production, processing and application. Its core purpose is to comprehensively evaluate its mechanical properties by simulating the tensile force that the film material may withstand in actual use, so as to ensure that the product quality meets the standards and application requirements.

[0003] Tensile testing of PE film is a key step in ensuring its production quality. However, in the existing testing process, the two ends of the film material need to be fixed and disassembled separately. This step-by-step operation at both ends makes the clamping and unclamping process before and after the test cumbersome and significantly reduces the overall testing efficiency. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a performance testing device for PE film, which solves the problem that in the existing testing process, the two ends of the film material need to be fixed and disassembled separately. This step-by-step operation at both ends makes the clamping and unclamping process before and after the test cumbersome and significantly reduces the overall testing efficiency.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a performance testing device for PE film, including a base, a test frame fixed on the base, a sliding groove on the test frame, a first motor fixedly installed on the top of the test frame, opposing threaded rods rotatably installed on the test frame, symmetrical first slides threadedly installed on the opposing threaded rods, the first slides slidably installed in the sliding groove, double-axis frames fixedly installed on opposite sides of the first slides, symmetrical connecting plates rotatably installed on the double-axis frames, shafts rotatably installed on the connecting plates, slide rods fixedly installed at both ends of the shafts, symmetrical clamps slidably installed on the slide rods, and a tensile drive assembly provided on the test frame.

[0006] Preferably, there are four shafts and four slide rods, and every two shafts and two slide rods form a rectangular structure and are parallel to each other.

[0007] Preferably, the tensile drive assembly includes opposing threaded tubes, which are rotatably fitted onto opposing threaded rods. A worm gear is fixedly installed in the middle of the opposing threaded tubes. A second motor is fixedly installed on the test frame. A worm is fixedly connected to the output end of the second motor. The worm meshes with the worm gear. The other end of the worm is rotatably installed on the test frame. A symmetrical second slide is threaded onto the opposing threaded tubes, and the second slide is slidably installed in a slide groove. A limit slide is provided on the second slide, and the clamping plate is slidably sleeved on the limit slide.

[0008] Preferably, the clamping plate is provided with clamping station components, and the number of clamping station components is at least five.

[0009] Preferably, the clamping station assembly includes clamping blocks, which are fixedly installed on opposite surfaces of the clamping plate. The clamping blocks are divided into two groups. One group of clamping blocks has positioning holes, and the other group of clamping blocks on opposite surfaces has positioning plugs fixedly installed on them, which can be inserted into the positioning holes.

[0010] Preferably, the clamping block is provided with friction texture, and the friction texture is arranged in a ring structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a first motor to drive the opposing threaded rod to rotate, which in turn drives the first slide to move synchronously in opposite directions. The two double-axis frames then pull the shaft through the connecting plate, causing the two opposing slides to clamp the clamps together. This allows for the simultaneous fixing or unfixing of both ends of the PE film used for testing, simplifying the clamping and unclamping process before and after testing and improving overall testing efficiency.

[0012] This invention, through the arrangement of clamping blocks, positioning holes, and positioning plugs, aligns the two ends of the test PE film between two opposing clamping blocks during the testing process. The clamping plates move closer together, causing the positioning plug to pierce through the test PE film and insert into the positioning hole. The two clamping blocks clamp the test PE film tightly, and the positioning plug generates a fixing force on the test PE film, thereby improving the positioning effect of the test PE film.

[0016] As attached Figure 1 To be continued Figure 6 This utility model provides a performance testing device for PE film, including a base 1, a test frame 2 fixed on the base 1, a slide groove 3 on the test frame 2, a first motor 4 fixedly installed on the top of the test frame 2, opposing threaded rods 5 rotatably installed on the test frame 2, symmetrical first slides 6 threadedly installed on the opposing threaded rods 5, the first slides 6 slidably installed in the slide groove 3, double shaft frames 7 fixedly installed on opposite sides of the first slides 6, symmetrical connecting plates 8 rotatably installed on the double shaft frames 7, shafts 9 rotatably installed on the connecting plates 8, slide rods 10 fixedly installed at both ends of the shafts 9, symmetrical clamping plates 11 slidably installed on the slide rods 10, and a tensile drive assembly 12 provided on the test frame 2.

[0017] Specifically, the clamping plate 11 is used to clamp the PE film. The first motor 4 drives the opposing threaded rod 5 to rotate, and the opposing threaded rod 5 drives the first slide 6 to move synchronously in opposite directions. The double-axis frame 7 pulls the shaft 9 through the connecting plate 8, so that the two opposing slides 10 drive the clamping plate 11 to clamp each other. This can fix or unfix both ends of the PE film used for testing at the same time, simplifying the clamping and unclamping process before and after testing and improving the overall testing efficiency.

[0018] Preferably, there are four shafts 9 and four slide rods 10, and every two shafts 9 and two slide rods 10 form a rectangular structure and are parallel to each other.

[0019] Preferably, the tension drive assembly 12 includes a counter-threaded tube 121, which is rotatably mounted on a counter-threaded rod 5. A worm gear 122 is fixedly installed in the middle of the counter-threaded tube 121. A second motor 123 is fixedly installed on the test frame 2. A worm 124 is fixedly connected to the output end of the second motor 123. The worm 124 meshes with the worm gear 122. The other end of the worm 124 is rotatably mounted on the test frame 2. A symmetrical second slide 125 is threadedly installed on the counter-threaded tube 121. The second slide 125 is slidably installed in the slide groove 3. A limiting slide 126 is provided on the second slide 125. The clamping plate 11 is slidably sleeved on the limiting slide 126.

[0020] Specifically, by starting the second motor 123, the worm gear 124 rotates and meshes with the worm wheel 122, which drives the opposing threaded tube 121 to rotate in the middle of the opposing threaded rod 5. The clamping plates 11 on both sides of the threaded drive of the second slide 125 drive the PE film for testing to perform a tensile test and detect the tensile properties of the PE film.

[0021] Preferably, the clamping plate 11 is provided with clamping station components 13, and the number of clamping station components 13 is at least five.

[0022] Preferably, the clamping station assembly 13 includes a clamping block 131, which is fixedly installed on the opposite surface of the clamping plate 11. The clamping blocks 131 are divided into two groups. One group of clamping blocks 131 has a positioning insertion hole 132, and the other group of clamping blocks 131 on the opposite surface has a positioning plug 133 corresponding to the positioning insertion hole 132 fixedly installed. The positioning plug 133 can be inserted into the positioning insertion hole 132.

[0023] Specifically, through the arrangement of clamping block 131, positioning hole 132, and positioning plug 133, during the testing of PE film, the two ends of the test PE film are aligned between two opposing clamping blocks 131, and the clamping plates 11 move closer to each other, so that the positioning plug 133 penetrates the test PE film and is inserted into the positioning hole 132. The two clamping blocks 131 clamp the test PE film, and the positioning plug 133 generates a fixing force on the test PE film, thereby improving the positioning effect of the test PE film.

[0024] Preferably, the clamping block 131 is provided with friction texture 134, which is arranged in a ring structure to further increase the friction force of the clamping block 131 on the test PE film and improve the positioning effect of the test PE film.

[0025] The working process of this utility model is as follows: In use, the first motor 4 drives the opposing threaded rod 5 to rotate, and the opposing threaded rod 5 drives the first slide 6 through the thread, which can drive the two double-shaft frames 7 to move synchronously in opposite directions. The double-shaft frames 7 pull the shaft 9 through the connecting plate 8, so that the clamping plates 11 on opposite sides are brought closer to each other, so that the positioning plug 133 penetrates the PE film used for testing and is inserted into the positioning socket 132. The two clamping blocks 131 clamp the PE film used for testing. Then, the second motor 123 is started, and the worm gear 124 rotates to mesh with the worm wheel 122, which can drive the opposing threaded tube 121 to rotate in the middle of the opposing threaded rod 5. The second slide 125 drives the clamping plates 11 on both sides through the thread to drive the PE film used for testing to perform a tensile test and detect the tensile performance of the PE film.
