[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made from polyester fibers and produced through a needle-punching process, allowing for different thicknesses, feels, and hardnesses. Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, lightness, thinness, flame retardancy, non-toxicity, odorlessness, low price, and recyclability. After processing, non-woven fabrics typically undergo tensile strength testing. However, in existing nonwoven fabric strength testing devices, the fixing structure for nonwoven fabric is relatively simple. Usually, the nonwoven fabric needs to be placed in the middle of the clamping blocks first, and then the clamping blocks need to be manually adjusted to bring them closer together to clamp the nonwoven fabric. When installing thinner and wider nonwoven fabrics, it is difficult for one person to hold the nonwoven fabric down while adjusting the clamping blocks, making the installation quite troublesome.

[0017] The mounting mechanism 4 also includes a first rotating roller 42, a slide rod 43, a connecting block 44, a pressure roller 45, a spring 46, and a first motor 47. The first rotating roller 42 is rotatably connected inside the mounting block 41, the slide rod 43 is slidably connected inside the mounting block 41, and there are two sets of slide rods 43. The connecting block 44 is fixedly connected to the bottom end of the slide rod 43, the pressure roller 45 is rotatably connected between the two sets of connecting blocks 44, the spring 46 is sleeved on the periphery of the slide rod 43, and the first motor 47 is fixedly connected to the right side of the mounting block 41. The output end of the first motor 47 is fixedly connected to the first rotating roller 42.

[0018] The mounting mechanism 4 also includes a first sensor 48 fixedly connected inside the mounting block 41 and a second sensor 49 fixedly connected inside the mounting block 41. Both the first sensor 48 and the second sensor 49 are photoelectric sensors.

[0019] The mounting mechanism 4 also includes a first telescopic cylinder 410 and a first pressure plate 411.

[0020] The upper end of the base 1 is fixedly connected to the upright plate 7, and there are two sets of upright plates 7. The two sets of upright plates 7 are rotatably connected to the guide roller 8, and there are two sets of guide roller 8.

[0025] In summary, the nonwoven fabric tensile strength testing device provided by this utility model, when in operation, places the upper end of the nonwoven fabric into the notch on the front of the mounting block 41. When the nonwoven fabric covers the first sensor 48, the first sensor 48 transmits a signal to the controller 14. Upon receiving the signal, the controller 14 controls the first motor 47 to start. The first motor 47 can drive the first rotating roller 42 to rotate. At this time, when the nonwoven fabric comes into contact with the first rotating roller 42 and the pressure roller 45, the first rotating roller 42 can drive the nonwoven fabric to move deeper into the mounting block 41. When the nonwoven fabric enters the deep interior of the mounting block 41 and covers the second sensor 49, the second sensor 49 transmits a signal to the controller 14. The controller 14 controls the first motor 47 to stop working and simultaneously controls the first telescopic cylinder 410 to drive the first pressure plate 411 downward to press the nonwoven fabric. When removing the nonwoven fabric, the controller 14 can first control the first telescopic cylinder 410 to drive the first pressure plate 411 upward, and then the nonwoven fabric can be pulled out. After the upper end of the nonwoven fabric is fixed, the bottom end hangs down naturally. At this time, the bottom end of the nonwoven fabric is placed between the two sets of guide rollers 8. The second motor 10 drives the guide rollers 8 to rotate, and the two sets of gears 9 can make the two sets of guide rollers 8 rotate at the same time. At this time, the bottom end of the nonwoven fabric can pass through the two sets of guide rollers 8 and enter the material trough 11. The second telescopic cylinder 13 drives the second pressure plate 12 to move forward to clamp the bottom end of the nonwoven fabric. This structure makes it very convenient to fix the bottom end of the nonwoven fabric.
