Description

Technical Field

[0001] The present invention relates to the technical field of cloth testing, and in particular to a device for testing the wear resistance of textile cloth. Background Art

[0002] Textile fabrics are made of textile fibers and are widely used in the production of various types of clothing, such as shirts, T-shirts, bedding, curtains, towels, etc. After production, wear resistance is a key indicator to measure its quality. Wear resistance testing can simulate the wear resistance of textile fabrics in actual use to judge the quality. Current wear resistance testing of textile fabrics mainly relies on machine-controlled friction plates to perform reciprocating friction, and the friction movement method is fixed. As a result, the test results are prone to deviations. During the test, the degree of friction on the surface of the fabric is usually judged after a specific number of frictions. This method cannot accurately perceive the subtle changes in the fabric during the friction process, and the test is not detailed enough. In addition, the friction contact objects used in the test are relatively simple and difficult to adapt to different types of fabrics, which in turn affects the accuracy of the test.

[0029] Specific usage and function of this embodiment: When the present invention is in use, the textile cloth to be tested is placed on the surface of the bottom support ring 505, and one side of the control support frame 502 is placed in the slide groove of the support block 501. The control support frame 502 is fixed by the locking screw 503, and the bottom pressure ring 504 of the control support frame 502 pushes the textile cloth into the groove of the bottom support ring 505 to form a fixation; the control screw 202 is rotated, and the threaded control on the surface of the control screw 202 drives the plate A204 and the sliding support plate 205 to slide down, driving the wear-resistant path control mechanism 3 and the friction force sense The response mechanism 4 moves and contacts with the textile cloth, controls the motor on the top of the rotating rod 301 to start, and the rotating disk 302 rotates. The rotating disk 302 controls one group of friction components 603 to perform a circular friction test on the surface of the textile cloth. Since the control rotating rod 301 is placed on one side of the rotating disk 302, the rotating disk 302 will push the connecting frame 304 to slide when it rotates, and the spring on the surface of the auxiliary support rod 305 will contract. The friction force sensing mechanism 4 on one side of the connecting frame 304 will reciprocate and move laterally for friction testing. The two mobile testing methods can better test the wear resistance of the textile cloth.

[0030] During friction, the friction force will change with the friction time. The external column 401 is affected by the friction force, and the external column 401 and the sliding column 403 connected by the connecting rod 404 will move accordingly. When the sliding column 403 moves, the inductive pull rope 405 inside the sliding column 403 is pulled and slides, thereby driving the pressing frame 407 to press down. The pressing frame 407 contacts the pressure sensor 408, and the friction pressure during the friction process is monitored in real time. As the number of times increases, the friction force will also change accordingly, which is convenient for testing. When facing different types of textile fabrics, different friction plates 6032 need to be replaced. The sliding support plate 205 can be controlled to slide down close to the fixed support plate 203. When the top box 601 and the bottom box 604 are docked, the hexagonal groove at the bottom of the threaded rod A602 docks with the linkage rod 606, and the threaded rod A602 contacts the threaded column 6033 of the friction assembly 603 provided in the bottom box 604. The main control rod 703 controls the rotation of the rotating ring 701 and the inner gear ring 702, and then controls the threaded rod B605 to rotate. The threaded rod B605 rotates and pushes the friction assembly 603 upward through the lifting frame 607. At this time, the threaded rod A602 is controlled and rotated at the same time. The threaded rod A602 rotates and is inserted into the threaded column 6033 to complete the connection and replacement. The sliding support plate 205 is controlled to be lifted again, the replacement of the friction assembly 603 is completed, and the next wear resistance test is carried out again.
