Description

Technical Field

[0001] The utility model relates to the technical field of fabric testing equipment, in particular to a multifunctional Martindale abrasion tester. Background Art

[0002] The Martindale abrasion test is a test of textile products based on the Martindale method standard system and its relationships, and is used to determine the wear resistance of fabrics. Conventional Martindale testers use a single-axis mechanical transmission to control the movement of the friction head along the Lissajous curve for abrasion testing. This curve is relatively simple, and switching between different Lissajous curves is cumbersome. Some existing equipment uses dual motors to control dual axes, which can produce a stable motion trajectory and can also generate any desired motion trajectory based on demand. However, it can only perform abrasion and pilling tests using the Lissajous curve. Pilling testers control the movement of the friction head along a circular trajectory to test the fabric's pilling resistance. Abrasion resistance, pilling, and fuzz are all fabric test indicators. Due to different test benches, a complete test requires two devices. This causes certain duplication problems in test execution and data recording, hindering test efficiency and urgently needs improvement. Utility Model Content

[0003] In order to address the deficiencies of the above-mentioned technologies, the present invention provides a multifunctional Martindale wear tester, comprising a mounting platform, an X-axis control mechanism, a Y-axis control mechanism, a connecting platform, a butterfly plate, a plurality of wear-resistant sample platforms, and a plurality of friction mechanisms for wear testing. The X-axis control mechanism is disposed in the mounting platform, the Y-axis control mechanism is disposed on the X-axis control mechanism, the connecting platform is disposed on the Y-axis control mechanism, the butterfly plate is rotatably connected to the connecting platform, the plurality of friction mechanisms are disposed on the butterfly plate, the plurality of wear-resistant sample platforms are disposed on the mounting platform, the mounting platform is further provided with a pilling sample platform, a fuzzing sample platform, and a testing mechanism for pilling testing. The testing mechanism comprises a friction head, a weight, a connecting rod, and a limit knob. The friction head and the weight are detachably connected, the connecting rod is fixedly connected to the weight, and the limit knob is threadedly connected to the connecting rod. A pair of mounting holes matching the connecting rods are formed on the butterfly plate at positions corresponding to the pilling sample platform and the fuzzing sample platform, and the testing mechanism is disposed in the mounting holes.

[0004] By adopting the above technical solution, by adding a pilling sample table and a fuzzing sample table to the mounting table, the wear resistance, pilling and pilling tests of the fabric can be carried out separately on the Martindale abrasion tester. When performing the pilling and pilling tests, it is only necessary to adjust the X-axis control mechanism and the Y-axis control mechanism to adjust the Lissajous trajectory curve originally used for the wear resistance test to a circular trajectory curve. This solves the problem that multiple instruments are required for fabric testing, saves a lot of time and labor spent in the pre-test stage, and improves the efficiency of the test.

[0005] The utility model is further configured as follows: the connecting rod includes a thick rod end and a thin rod end, the size of the thick rod end matches the mounting hole, and the butterfly plate is provided with sliding grooves that match the thin rod end and are respectively connected to a pair of mounting holes.

[0006] With the above technical solution, since the connecting rod includes a thick rod end and a thin rod end, the size of the thick rod end matches the mounting hole, and the butterfly plate is provided with sliding grooves that match the thin rod end and are respectively connected to a pair of mounting holes, when the fabric is switched between the fuzzing and pilling test benches, the testing mechanism does not need to be reinstalled. The testing mechanism only needs to be lifted and moved along the sliding groove to quickly transfer the testing mechanism from above the fuzzing sample bench to above the pilling sample bench, thereby further improving the testing efficiency.

[0007] The utility model is further configured as follows: a suspension hole is provided on the sliding groove at a position in the middle of a pair of mounting holes; the radius of the suspension hole is larger than the width of the sliding groove and smaller than the radius of the mounting hole; and a chamfer is provided at the connection between the thick rod end and the thin rod end.

[0008] According to the above technical solution, since a suspension hole is provided on the sliding groove at a position between the pair of mounting holes, the radius of the suspension hole is greater than the width of the sliding groove and smaller than the radius of the mounting hole, and a chamfer is provided at the connection between the thick rod end and the thin rod end, when a wear test is performed instead of a pilling or fuzzing test, the test mechanism can be lifted and moved along the sliding groove to the position of the suspension hole and then lowered. After lowering, the friction head of the test device will not contact the surface of the pilling sample table, so that the wear test can be carried out smoothly without removing the test device, further facilitating the test.

[0009] The present invention is further configured as follows: a limiting groove is further provided in the pair of mounting holes, and a limiting block matching the limiting groove is provided on the end of the thick rod.

[0010] By adopting the above technical solution, since a limit groove is also provided in the pair of mounting holes, and a limit block matching the limit groove is provided on the end of the thick rod, the test device itself will not rotate circumferentially when it moves with the butterfly plate in the mounting hole, thereby ensuring the effectiveness of the test.

The friction head and weight are detachably connected, the connecting rod is fixedly connected to the weight, and the limit knob is threadedly connected to the connecting rod. A pair of mounting holes 15 are provided on the butterfly plate at positions corresponding to the pilling sample platforms and the fuzzing sample platforms, matching the connecting rods, and the testing mechanism is disposed within the mounting holes.

[0016] By adding a pilling sample table and a fuzzing sample table to the mounting table, the wear resistance, pilling and balling tests of fabrics can be performed separately on the Martindale abrasion tester. When performing the pilling and balling tests, it is only necessary to adjust the X-axis control mechanism and the Y-axis control mechanism to adjust the Lissajous trajectory curve originally used for the wear resistance test to a circular trajectory curve. This solves the problem of requiring multiple instruments for fabric testing, saves a lot of time and labor spent in the pre-test process, and improves the efficiency of the test.

[0018] Since the connecting rod includes a thick rod end and a thin rod end, the size of the thick rod end matches the mounting hole, and the butterfly plate is provided with sliding grooves that match the thin rod end and are respectively connected to a pair of mounting holes, when the fabric is switched between the fuzzing and pilling test benches, the testing mechanism does not need to be reinstalled.

The radius of the suspension hole is larger than the width of the sliding groove and smaller than the radius of the mounting hole. A chamfer 20 is provided at the connection between the thick rod end and the thin rod end.

[0020] Since a suspension hole is provided on the sliding groove at a position between the pair of mounting holes, the radius of the suspension hole is greater than the width of the sliding groove and smaller than the radius of the mounting hole, and a chamfer is provided at the connection between the thick rod end and the thin rod end, when a wear test is performed instead of a pilling or fuzzing test, the test mechanism can be lifted and moved along the sliding groove to the position of the suspension hole and then lowered. After lowering, the friction head of the test device will not contact the surface of the pilling or fuzzing specimen table, so that the wear test can be carried out smoothly without removing the test device, further facilitating the test.
