[0018] Example 1

[0019] like Figures 1 to 3 As shown, the present invention proposes a device for testing the abrasion resistance of composite fiber fabrics, including a testing platform 1, a fabric seat 303, a friction mechanism, and a placement rack 5; a reciprocating motion mechanism is provided at the top of the testing platform 1; multiple sets of fabric seats 303 are provided, and the multiple sets of fabric seats 303 are driven by the reciprocating motion mechanism to slide back and forth along the horizontal direction of the testing platform 1; the friction mechanism is located at the top of the testing platform 1, and the friction mechanism consists of a support column 101 installed at the top of the testing platform 1, a movable seat 102 adjustablely connected to the support column 101, a slide rod 2 slidably connected to the movable seat 102, and a mounting bracket 5 installed on the slide rod 2. The friction head 201 at the bottom and the limiting rod 202 installed at the top of the friction head 201 are composed of a friction head 201 and a fabric seat 303. Both the friction head 201 and the fabric seat 303 are equipped with limiting components. The friction head 201 and the fabric seat 303 have the same structure. The fabric seat 303 is larger than the friction head 201. Two sets of sliding rods 2 are provided on the friction head 201. The placement frame 5 is installed at the top of the testing table 1 and distributed above the moving frame 301. Multiple sets of uprights 501 are provided at the top of the placement frame 5. Multiple sets of weights 502 of different weights are inserted into the uprights 501. The weights 502 are slidably inserted into the limiting rods 202.

[0020] Furthermore, the reciprocating motion mechanism includes a drive rod 3 and a moving frame 301; the drive rod 3 is driven to rotate by a motor mounted on the testing table 1, and the other end of the drive rod 3 is rotatably connected to a transmission rod 302; one end of the moving frame 301 is hinged to the other end of the transmission rod 302, and the other end is connected to the side wall of multiple sets of fabric seats 303.

[0021] Furthermore, a slider 304 is installed at the bottom of the fabric seat 303. The slider 304 is T-shaped, and a groove 104 is provided on the detection table 1. The slider 304 is slidably connected to the groove 104.

[0022] Furthermore, the support column 101 is provided in two sets, and the movable seat 102 is slidably sleeved between the two sets of support columns 101. The movable seat 102 is threaded with bolts, and the abutting end of the bolts abuts against the support column 101. The abutting end of the bolts is provided with an anti-slip pad.

[0023] Furthermore, the weight 502 has an installation port 503, which is U-shaped. The installation port 503 is slidably inserted into the limiting rod 202, which facilitates the quick installation or removal of weights 502 and limiting rod 202 of different weights.

[0024] In this embodiment, initially, multiple fabric seats 303 are positioned in front of the top of the testing platform 1 and slightly offset from the corresponding friction heads 201. Friction material is installed at the bottom of the friction heads 201 via a limiting component, and composite fiber fabric samples are installed on the fabric seats 303 via the limiting component. It should be noted that the same composite fiber fabric sample can be installed on multiple fabric seats 303 to obtain the wear resistance of the material under different friction factors. Different materials can also be installed on multiple fabric seats 303, while the same friction material is installed on multiple friction heads 201 to obtain the wear resistance of different fabrics under the same friction factor. This makes the use more flexible and easier to adjust. Rotating the bolts moves the abutting end away from the support column 101, thereby moving the seat... 102 slides down along the support column 101 until the friction material at the bottom of the friction head 201 contacts the sample material on the fabric seat 303. The controller starts the motor to drive the drive rod 3 to rotate, which in turn drives the moving frame 301 to slide back and forth along the horizontal direction of the test table 1 through the transmission rod 302. This, in turn, drives multiple sets of fabric seats 303 to move back and forth along the horizontal direction of the test table 1. This, in turn, drives the composite fiber fabric sample on the fabric seat 303 to move back and forth with the friction material on the friction head 201 to perform abrasion resistance testing. It should be noted that the weight 502 on the upright 501 can be removed and installed on the limit rod 202, which can adjust the friction force of the friction material on the friction head 201 on the composite fiber fabric, thereby obtaining a wider range of abrasion resistance data.

[0025] Example 2

[0026] like Figures 3 to 4 As shown, the abrasion resistance testing device for composite fiber fabric proposed in this utility model, compared with Embodiment 1, includes a limiting component comprising a clamping seat 4, an insert rod 401, and a locking rod 403; the clamping seat 4 is sleeved on the outer circumferential surface of the friction head 201 or the fabric seat 303; the insert rod 401 is inserted into the clamping seat 4, and ear seats are provided at both ends of the clamping seat 4, the insert rod 401 is slidably inserted into the two sets of ear seats, and a threaded seat 402 is threadedly connected to the insert rod 401, the threaded seat 402 abutting against the clamping seat 4; the locking rod 403 is rotatably connected to the end of the insert rod 401 away from the threaded seat 402, the rotating end of the locking rod 403 is provided with an abutting part 404 and a clearance part 405, the abutting part 404 abutting against the clamping seat 4, and the clearance part 405 is located away from the clamping seat 4.

[0027] In this embodiment, the sample of composite fiber fabric is placed on multiple sets of fabric seats 303, or the friction material is placed at the bottom of the friction head 201. The clamping seat 4 is sleeved on the outside of the friction head 201 or the fabric seat 303. Then, the insertion rod 401 is inserted into the clamping seat 4, so that the threaded seat 402 abuts against the clamping seat 4. The locking rod 403 is rotated so that the abutting part 404 abuts against the other end of the clamping seat 4, thereby locking and fixing both ends of the clamping seat 4 to the outer peripheral surface of the friction head 201 or the fabric seat 303. This fixes and limits the sample of composite fiber fabric or friction material, making it easy to disassemble and improve the testing efficiency.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
