[0034] The moving mechanism comprises four pairs of return springs 23, a sliding groove 24 is arranged below the top end of the detection machine 1 relative to the sliding block 7, the bottom end of the sliding block 7 is fixedly connected with a sliding plate 25, the sliding plate 25 is slidingly connected to the inner side of the sliding groove 24, and the return spring 23 is fixedly connected between the sliding groove 24 and the sliding plate 25; the detection machine 1 is provided with a positioning mechanism for limiting the position of the sliding block 7, and the sliding block 7 is made of iron;

[0035] The positioning mechanism comprises four pairs of vertical plates 27, each pair of vertical plates 27 is fixedly connected to the top end of the detection machine 1 relative to the position beside the sliding block 7, the side wall of the vertical plate 27 is slidingly connected with a T-shaped block 28, the side end bottom of the T-shaped block 28 is fixedly connected with a bottom right-angle block 29 with an inclined surface, the top end of the bottom right-angle block 29 is fixedly connected with a top right-angle block 30 with an inclined surface, a pair of positioning springs 31 is fixedly connected between the side wall of the vertical plate 27 and the side wall of the T-shaped block 28, the top end of the sliding block 7 is fixedly connected with a positioning plate 32 relative to the position beside the plane of the bottom right-angle block 29, and the end, away from the bottom right-angle block 29, of the positioning plate 32 is arranged as a smooth circular arc surface;

[0036] The side wall of the limiting block 9 is fixedly connected with an extrusion strip 33, the side end of the extrusion strip 33 is arranged as a smooth circular arc surface, the extrusion strip 33 is arranged beside the top right-angle block 30, and is staggered between the bottom right-angle block 29, so that the sliding of the bottom right-angle block 29 is not limited;

[0037] In the process of detecting the wear resistance of the textile fabric, when it is necessary to release the limitation of the fabric on the detection machine 1, first, the electric telescopic cylinders 19 are controlled to start to drive the lower right-angle block 21 and the push plate 22 to move (at this time, the push plate 22 is beside the round rod 14), then the push plate 22 pushes the round rod 14 to move, thereby driving the limiting block 9 to slide in the groove 8, and gradually pushing the elastic spring 18, at this time, the straight-angle groove 10 on the limiting block 9 is removed from the upper right-angle block 13, thereby releasing the upward movement limitation of the upper right-angle block 13 and the locking block 12, then the locking cover 6 is pulled to move upward under the elastic force of the return spring 16, thereby pulling the locking cover 6 away from the setting-out plate 5, releasing the clamping and fixing of the textile fabric on the setting-out plate 5, then the round rod 14 is continuously pushed to move by the push plate 22, thereby driving the extrusion strip 33 on the limiting block 9 to move to the position beside the top right-angle block 30;

[0038] Further, the inclined surface of the straight angle block 30 is extruded by the arc surface of the extrusion strip 33. Since the straight angle block 30 and the T-shaped block 28 cannot move along the sliding direction of the limiting block 9, under the extrusion of the arc surface of the extrusion strip 33, the straight angle block 30 and the T-shaped block 28 are pushed to slide away from the sliding block 7, and the positioning spring 31 is stretched, and the bottom straight angle block 29 is moved away from the positioning plate 32, thereby releasing the sliding limitation of the sliding block 7. Then, under the elastic force of the return spring 23, the sliding block 7 is pulled to reset (at this time, the straight angle block 30 is still extruded by the side of the extrusion strip 33), thereby pulling the locking cover 6 away from the lofting plate 5, and then the circular rod 14 is moved away from the push plate 22, and under the elastic force of the push spring 18, the limiting block 9 is pushed to reset (at this time, the upper straight angle block 13 on the locking cover 6 is inserted into the uppermost straight angle groove 10), thereby automatically releasing the limitation of the fabric, and then the tested fabric can be taken out and placed in the textile fabric to be detected.

[0039] In summary, through the design of the above structure, the limitation of the locking cover 6 can be automatically released, and the limitation of the textile fabric on the lofting plate 5 is also released. Then, the position limitation of the sliding block 7 is automatically released, and under the elastic force of the return spring 23, the sliding block 7 and the locking cover 6 are pulled away from the lofting plate 5, and the textile fabric can be taken out and replaced.

[0040] Based on the above embodiment, it is found that the above structure can automatically release the limitation of the textile fabric, but after replacing the fabric, the detection personnel still need to clamp it, which is more troublesome. In order to solve the above problem, the above structure is further improved.

[0041] The detection machine 1 is provided with an insertion frame 34 beside one of the lofting plates 5, and the driving block 20 is slidingly connected to the inner side of the insertion frame 34. The insertion frame 34 is rotatably connected to the inner side of the insertion frame 34. The insertion frame 34 is fixedly connected to the side wall of the insertion frame 34. The output end of the driving motor 36 is fixedly connected to the side wall of the bidirectional screw rod 35 through the inner side of the insertion frame 34. The bidirectional screw rod 35 is threadedly connected to the inner side wall of the driving block 20.

[0042] When the textile fabric on the lofting plate 5 is replaced, the driving motor 36 is controlled to start driving the bidirectional screw rod 35 to rotate, thereby driving the driving block 20 connected with the screw rod 35 to move to the middle, and driving the electric telescopic cylinder 19, the lower right-angle block 21 and the push plate 22 to move, and then the electromagnet 26 on the lower right-angle block 21 moves to the position beside the sliding block 7, and the electric telescopic cylinder 19 is controlled to start driving the lower right-angle block 21 and the electromagnet 26 to move to the position beside the reset sliding block 7, and when the electromagnet 26 moves to the position beside the sliding block 7, the electromagnet 26 is energized to attract the sliding block 7, and then the electric telescopic cylinder 19 is controlled to reset, thereby pulling the sliding block 7 and the locking cover 6 to move to one side of the lofting plate 5, and driving the sliding plate 25 to slide in the sliding groove 24, and stretching the return spring 23;

[0043] Then the extrusion strip 33 moves away from the top right-angle block 30, and the extrusion on the top right-angle block 30 is released, and then the T-shaped block 28, the top right-angle block 30 and the bottom right-angle block 29 are pushed to reset under the elastic force of the positioning spring 31, and then the positioning plate 32 on the sliding block 7 moves to the position beside the bottom right-angle block 29, and then the bottom right-angle block 29 and the T-shaped block 28 slide away from the locking cover 6 under the extrusion of the arc surface of the positioning plate 32, and the positioning spring 31 is stretched, and then when the positioning plate 32 moves away from the bottom right-angle block 29, the bottom right-angle block 29 is pushed to reset under the elastic force of the positioning spring 31, and the plane of the bottom right-angle block 29 is clamped beside the positioning plate 32, and at this time, the sliding block 7 is moved to the position, and the bottom right-angle block 29 limits the reset of the sliding block 7;

[0044] Finally, the electromagnet 26 is turned off, the driving motor 36 is controlled to continue driving the driving block 20 to move to the middle, and the electric telescopic cylinder 19 is controlled to completely stretch back, so that the lower right-angle block 21 moves to the position beside the locking cover 6, and the electric telescopic cylinder 19 is controlled to drive the lower right-angle block 21 to move, and since the locking cover 6 can only move up and down between the sliding blocks 7, the locking cover 6 moves downward under the extrusion of the inclined surface of the lower right-angle block 21, and gradually compresses the reset spring 16, and drives the locking block 12 and the upper right-angle block 13 to move downward, and at this time, the inclined surface of the right-angle groove 10 extrudes the inclined surface of the upper right-angle block 13, so that the upper right-angle block 13 and the locking block 12 slide into the U-shaped block 11, and compress the locking spring 17, and then when the upper right-angle block 13 moves to the position beside the lower right-angle groove 10, the extrusion on the upper right-angle block 13 is released, and then the upper right-angle block 13 is pushed to insert into the corresponding right-angle groove 10 under the elastic force of the locking spring 17, and the above process is repeated until the locking cover 6 clamps the fabric on the lofting plate 5, so as to realize the automatic clamping of the fabric.

[0045] As described above, through the design of the above structure, after the fabric is placed, the sliding block 7 can be automatically pulled back, and the locking cover 6 can be locked on the lofting plate 5, so as to realize the automatic clamping of the fabric on the Martindale abrasion tester, which saves time and effort, and greatly improves the detection efficiency of the device.

[0046] On the basis of the above-mentioned embodiments, it is found in use that if the position of the releasing mechanism is fixed, multiple releasing mechanisms need to be arranged to release the locking cover 6 on multiple stations on the detection machine 1, which will increase the cost of the equipment. In order to solve the above-mentioned problems, the above-mentioned structure is further improved.

[0047] The top end of the detection machine 1 is provided with a slot 37 beside the lofting plate 5, and the bottom end of the insertion frame 34 is fixedly connected with an insertion block 38, and the insertion block 38 is made of a material with magnetic force. The material around the slot 37 of the detection machine 1 is made of iron material. Through the design of the material, the position of the insertion frame 34 on the detection machine 1 can be adsorbed and limited, and the magnetic attraction of the material does not need to use strong magnetic material, and can be pulled out conveniently.

[0048] When it is needed to automatically clamp the fabric on other lofting plates 5 on the detection machine 1, the insertion block 38 on the insertion frame 34 can be pulled out from the slot 37 and inserted into the slot 37 beside the corresponding lofting plate 5 (it needs to be noted that when installing, the lower right-angle block 21 needs to be installed towards the lofting plate 5).

[0049] As described above, through the design of the above-mentioned structure, the releasing mechanism can be flexibly inserted beside any lofting plate 5 on the martin daier abrasion tester, and then the fabric on different stations can be flexibly automatically clamped, and the flexibility of the device is further improved.

[0050] The above shows and describes the basic principles, main features and advantages of the present application.

[0051] Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
