Description

Technical Field

[0001] This utility model relates to the technical field of non-textile testing devices, and more specifically to a non-textile fabric strength tester. Background Technology

[0002] A tensile testing machine is a key device for testing the mechanical properties of materials, such as breaking strength, tear strength, or repeated tensile testing under a quantitative load, to ensure that the mechanical properties of materials meet design requirements and safety standards.

[0003] Non-woven fabrics are made of fibrous materials and are characterized by their light weight and softness. After production, non-woven fabrics need to undergo tensile testing. In current testing methods, multiple pieces of fabric of the same area are often cut and stretched until they break. The test values ​​are recorded and compared to improve the accuracy of the data. However, only one piece of fabric can be clamped for testing at a time. After the test is completed, the fabric needs to be clamped again for testing. This testing process needs to be repeated multiple times, and each clamping requires calibration. As a result, the clamping and disassembling process takes a lot of time, which affects the testing efficiency of the fabric. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies and to solve the issue that multiple tests require multiple clamping operations, which in turn affects testing efficiency.

[0005] To achieve the above objectives, this utility model can be implemented through the following technical solution: a non-woven fabric strength testing machine, comprising a fabric body, and further comprising:

[0006] A base, on which a support is provided;

[0007] A clamping unit is disposed on the bracket. The clamping unit includes a support plate and a test platform arranged in a linear array on the base. The test platform is provided with clamping members that clamp the fabric body, and the clamping members are provided with linkage blocks.

[0027] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0028] like Figure 1-4 As shown, a non-woven fabric strength tester includes a fabric body 6, and also includes:

[0029] Base 1, with a bracket 3 mounted on it;

[0030] Clamping unit 2 is mounted on bracket 3. Clamping unit 2 includes support plate 20 and test table 23 arranged in a linear array on base 1. Clamping member 21 for clamping fabric body 6 is mounted on test table 23. Linkage block 22 is mounted on clamping member 21.

[0031] Transmission unit 5, which is mounted on bracket 3;

[0032] The detection unit 4 is slidably mounted on the bracket 3. The detection unit 4 includes a slide plate 41 and a transverse slide 44 slidably mounted on the slide plate 41. A pressure sensor 48 is mounted on the slide, and a locking block 47 that engages with the linkage block 22 is mounted on the output end of the pressure sensor 48.

[0033] Specifically, the support 3 is made of profiles and aluminum plates, and is fixed to the base 1 by reinforcing blocks 33 to improve the stability of the device during operation. When testing the fabric body 6, multiple fabric bodies 6 of the same area are pre-cut, and the width of the cut is smaller than the width of the clamping block 215. Then, the fabric bodies 6 are placed one by one on the clamping member 21, and the clamping member 21 is used to fix the fabric bodies 6. At this time, the transmission unit 5 runs to control the detection unit 4 to move closer to the clamping member 21 until the locking block 47 engages with the linkage block 22. Then, the second motor 51 of the transmission unit 5 rotates in the direction of the detection unit 4 to make the clamping member 21 slide along the test table 23 through the locking block 47 until the fabric body 6 is tensile deformed or broken. The pressure sensor 48 is observed to record the corresponding value, and then the first motor 42 controls the second motor 51 to move the detection unit 4 closer to the clamping member 21 until the fabric body 6 is tensile deformed or broken. A screw 43 rotates to make the transverse slide 44 slide laterally on the slide plate 41, so that the clamp 47 is aligned with another set of clamping parts 21. Then, a tensile test is performed. After multiple sets of tests are completed, the recorded values ​​are compared to improve the accuracy of the tensile test. The device can perform multiple sets of tensile tests at one time, thereby improving the testing efficiency. The pressure sensor 48 is model MIK-P300-B. The base 1 is further equipped with a control panel 12 and a foot 11. The control panel 12 controls the output power of the first motor 42 and the second motor 51. The first motor 42 and the second motor 51 are both model MSMF022L1, and the two motors are different sizes. The bottom of the foot 11 is made of rubber to improve the stability of the device during operation.

[0034] As a further embodiment of this utility model, the linkage block 22 is provided with a slot 222, and an inclined surface 221 is provided on one side of the slot 222. The locking block 47 is engaged in the slot 222 along the inclined surface 221. When the detection unit 4 slides closer to the clamping member 21, the locking block 47 will be pre-fitted to the inclined surface 221 and engaged in the slot 222 along the inclined surface 221. When the detection unit 4 moves away from the clamping member 21, the clamping member 21 will be driven to slide upward through the locking block 47, thereby performing a tensile test on the fabric body 6.

[0035] As a further embodiment of this utility model, the clamping member 21 consists of two parts, one of which slides on the support plate 20, while the other clamping member 21 is fixed on the test table 23. The clamping member 21 includes a bonding block 214 and a clamping block 215 slidably disposed on the bonding block 214. The clamping block 215 is provided with a locking member 213 that is threadedly connected to the bonding block 214. The bonding block 214 is fixed to the test table 23 by bolts. When the fabric body 6 is placed on the bonding block 214, the clamping block 215 moves closer to the bonding block 214 by the locking member 213, thereby clamping the fabric body 6. The locking member 213 can be a bolt.

[0036] As a further embodiment of this utility model, the clamping block 215 is provided with arc-shaped protrusions 212 arranged in a linear array, and the bonding block 214 is provided with arc grooves 211 that abut against the arc-shaped protrusions 212. The arc-shaped protrusions 212 increase the clamping area of ​​the fabric body 6. The multiple arc-shaped protrusions 212 allow the worker to better control the clamping amount of the fabric body 6, so that the clamping amount of multiple sets of fabric bodies 6 is consistent, thereby reducing the impact of clamping.

[0037] As a further embodiment of this utility model, a groove 231 is provided on the support plate 20, and a first spring 24 is provided between the clamping member 21 and the groove 231. The elastic force of the first spring 24 is used to push the clamping member 21 to slide within the groove 231 for resetting.

[0038] As a further embodiment provided by this utility model, at least three sets of clamping members 21 are provided. The more clamping members 21 there are, the more fabric bodies 6 can be clamped at once, and the better the comparability of the test data will be.

[0039] As a further embodiment of this utility model, a first motor 42 is provided on the slide plate 41, and a first screw 43 is provided at the output end of the first motor 42. The first screw 43 is threadedly engaged with the transverse slide 44. When the first motor 42 is running, it drives the first screw 43 to rotate so that the transverse slide 44 slides on the slide plate 41, thereby aligning the locking block 47 with the single set of clamping blocks 215.

[0040] As a further embodiment of this utility model, a concave block 46 is slidably disposed on the transverse slide 44, abutting against the output end of the pressure sensor 48. A second spring 45 is disposed between the concave block 46 and the locking block 47. The locking block 47 slides on the concave block 46. The elastic force of the second spring 45 is used to reset the locking block 47 after it is separated from the clamping block 215. At the same time, when the locking block 47 abuts against the clamping block 215, the second spring 45 is in a compressed state. When the locking block 47 slides into the slot 222, the elastic force of the second spring 45 is used to improve the connection effect between the locking block 47 and the clamping block 215.

[0041] As a further embodiment of this utility model, the transmission unit 5 includes a second motor 51 and a second screw 54 disposed at the output end of the second motor 51. A transmission block 53 connected to the slide plate 41 is threaded onto the second screw 54. The second motor 51 rotates to control the slide plate 41 to slide on the bracket 3. When the second motor 51 is running, it controls the rotation of the second screw 54 through the coupling 52 on the output end, so that the slide plate 41 slides along the bracket 3, thereby adjusting the distance between the detection unit 4 and the clamping member 21.

[0042] As a further embodiment of this utility model, a slide rail 31 is provided on the bracket 3, and a guide block 32 connected to the slide plate 41 is provided on the slide rail 31. The slide rail 31 and the guide block 32 improve the stability of the slide plate 41 during the sliding process, so as to reduce the swaying effect during the tensile test and improve the accuracy of the test values.

[0043] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.
