Description

Technical Field

[0001] The present invention relates to the technical field of fabric performance testing, and particularly to a Martindale abrasion tester. Background Art

[0002] Fabric performance testing refers to the process of detecting and evaluating the physical, chemical, mechanical, appearance and other aspects of various fabrics through a series of professional experimental methods and equipment, aiming to comprehensively understand the characteristics and quality of fabrics, and providing a scientific basis for fabric production, processing, application and product quality control. Among them, testers often use Martindale abrasion testers to conduct relevant performance tests on different fabrics.

[0003] At present, the Martindale abrasion tester uses a specific mechanical structure or motor drive system to generate a specific relative motion trajectory between the specimen and the friction material. When the specimen contacts the friction material and makes a relative motion, a frictional force will be generated between them. The magnitude of the frictional force is related to factors such as the materials of the specimen and the friction material, surface roughness, and the applied pressure. Finally, an optoelectronic sensor is used to accurately record the number of frictions, and corresponding parameters are obtained. However, in this process, the friction blocks of the Martindale abrasion tester often have a single shape, resulting in the inability to meet the test requirements of different fabrics. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a Martindale abrasion tester, which solves the problem that the single shape of the friction blocks of the Martindale abrasion tester cannot meet the test requirements of different fabrics.

[0013] Preferably, a connection hole is arranged inside the cover block, and the outer wall of the water inlet pipe is threadedly connected inside the connection hole.

[0014] Preferably, a water inlet hole is arranged inside the water inlet pipe.

[0015] Working principle: By starting the tester body to drive the moving block to move along a set trajectory. The tester body is a prior art and will not be elaborated here. Then, the limiting column drives the friction block to repeatedly rub the test cloth installed between the placing table and the positioning block. Before the test, by respectively pulling the limiting column and the friction block, the first connecting block will move synchronously under the drive of the friction block. Then, the pressing block will move synchronously under the drive of the first connecting block. Subsequently, the second connecting block disengages from between the first clamping block and the second clamping block. At this time, the first clamping block and the second clamping block close and no longer fix the second connecting block. Then, the pressing block moves under the drive of the first clamping block, and immediately the reset spring undergoes elastic deformation under the drive of the pressing block. The fixed block provides a fulcrum for the reset spring to maintain stability. Finally, it realizes the rapid separation and installation of the limiting column and the friction block, so as to achieve the effect of replacing the friction block with corresponding materials and shapes according to the requirements of different fabric tests.

[0016] By rotating the cover block, the water inlet pipe is disengaged from the cover block. At this time, the upper side of the water inlet hole is exposed to the outside. The tester supplements a certain amount of water into the friction block through the water inlet hole, thereby changing the weight of the friction block, so as to achieve the effect of facilitating the tester to obtain different data of the same test group under different pressures and saving the time for disassembling the friction block.

[0017] By covering the cover block on the surface of the water inlet pipe, the cover block can shield the interface between the water inlet hole and the outside world, maintain the sealing of the water storage tank inside the friction block, so as to prevent air from entering, avoid air corrosion of the friction block, and extend the service life of the friction block.

[0018] The present invention provides a Martindale abrasion tester, which has the following beneficial effects: 1. In the present invention, by starting the tester body to drive the moving block to move along a set track, and then the limiting column drives the friction block to repeatedly rub the test cloth installed between the placing table and the positioning block. Before the test, by pulling the limiting column and the friction block respectively, the connecting block 1 moves synchronously under the drive of the friction block, and then the pressing block moves synchronously under the drive of the connecting block 1, so as to achieve the effect of replacing the friction block with corresponding materials and shapes according to the requirements of different fabric tests.

[0019] 2. In the present invention, by rotating the cover block, the water inlet pipe is separated from the cover block. At this time, the upper side of the water inlet hole is exposed to the outside world. The tester fills a certain amount of water into the friction block through the water inlet hole, thereby changing the weight of the friction block, so as to achieve the effect of facilitating the tester to obtain different data of the same test group under different pressures and saving the time for disassembling the friction block.

[0020] 3. In the present invention, by connecting the cover block to the surface of the water inlet pipe, the cover block shields the interface between the water inlet hole and the outside world, so as to achieve the effect of maintaining the sealing of the water storage tank inside the friction block, avoiding air corrosion of the friction block, and thus achieving the effect of extending the service life of the friction block.

[0025] Specifically, by starting the tester body 1 to drive the moving block 2 to move along a set track. The tester body 1 is a prior art and will not be elaborated here. Then, the limiting post 3 drives the friction block 6 to repeatedly rub the test cloth installed between the placing table 4 and the positioning block 5. Before the test, by respectively pulling the limiting post 3 and the friction block 6, then the friction block 6 drives the connecting component to move synchronously, and then the connecting component disengages from the limiting component. After that, the reset component deforms under the drive of the clamping block one 9 to assist the limiting component to reset. Finally, the rapid separation and installation of the limiting post 3 and the friction block 6 are realized, so that the effect of replacing the friction block 6 with corresponding materials and shapes according to the requirements of different fabric tests can be achieved.

[0026] Refer to the attached Figure 4 and attached Figure 5 As shown in the figure, the connecting component includes a connecting block one 7. The lower surface of the connecting block one 7 is fixedly connected to the upper surface of the friction block 6. The upper surface of the connecting block one 7 is fixedly connected to a connecting block two 8.

[0027] Specifically, since the first connecting block 7 is fixedly connected to the friction block 6, the first connecting block 7 moves synchronously under the drive of the friction block 6. Since the pressing block 14 is fixedly connected to the first connecting block 7, the pressing block 14 moves synchronously under the drive of the first connecting block 7.

[0028] Refer to the appendix Figure 5 , the limiting component includes a first clamping block 9. The inner wall of the first clamping block 9 is fixedly connected to the outer wall of the rotating shaft 11. A second clamping block 10 is fixedly connected to the outer wall of the rotating shaft 11. The outer wall of the first clamping block 9 is arranged inside the inner wall of the second clamping block 10.

[0029] Specifically, the second connecting block 8 disengages from between the first clamping block 9 and the second clamping block 10. At this time, the first clamping block 9 and the second clamping block 10 close and no longer fix the second connecting block 8.

A pressing block 14 is arranged at the bottom end of the reset spring 13; Specifically, the pressing block 14 moves under the drive of the first clamping block 9. Since the reset spring 13 is fixedly connected to the pressing block 14, the reset spring 13 undergoes elastic deformation under the drive of the pressing block 14. The fixed block 12 provides a fulcrum for the reset spring 13 to maintain stability.

The outer wall of the water inlet pipe 15 is threadedly connected inside the connection hole 19; A water inlet hole 17 is opened inside the water inlet pipe 15.

[0034] Specifically, by rotating the cover block 16, the water inlet pipe 15 is disengaged from the inside of the connection hole 19. At this time, the upper side of the water inlet hole 17 is exposed to the outside. The tester supplements a certain amount of water into the water storage tank 18 through the water inlet hole 17. At this time, the weight of the friction block 6 changes accordingly. The installation of the nameplate 20 facilitates the tester to understand the test performance of the tester body 1, so that the tester can conveniently obtain different data of the same test group under different pressures, saving the time for disassembling the friction block 6; by connecting the cover block 16 to the surface of the water inlet pipe 15, the cover block 16 shields the interface between the water inlet hole 17 and the outside, so as to achieve the effect of maintaining the sealing of the water storage tank 18 inside the friction block 6 and preventing the friction block 6 from being corroded by air, thereby achieving the effect of extending the service life of the friction block 6.
