Description

Technical Field

[0001] The utility model relates to the technical field of textile testing equipment, in particular to a fabric friction testing machine. Background Art

[0002] The fabric friction test is one of the important means to evaluate the wear resistance and durability of fabrics. In textile quality inspection, the friction test simulates the friction situation of fabrics in actual use to evaluate the wear degree, durability and service life of fabrics. Currently, the fabric friction test equipment used in the market usually requires manual installation of the fabric sample in the test device. The user clamps the fabric sample on the test platform through a fixed support and applies a certain pressure on the sample for the friction test.

[0003] Most of the existing fabric sample fixing devices rely on detachable supports for clamping and fixing the samples. Each time a friction test is carried out, the user needs to manually install the detachable support and fix the fabric sample on the support. Using the detachable support requires multiple manual operations, which easily leads to improper installation or misalignment of the support, thereby affecting the fixing effect of the sample. Especially when reinstalling the support, it is often difficult to align, resulting in deviation in the position of the sample after each installation. This inconsistency directly affects the repeatability of the friction test and further affects the reliability of the test results.

[0004] Therefore, we propose a fabric friction testing machine. Content of the Utility Model

[0005] The utility model mainly solves the above technical problems and provides a fabric friction testing machine.

[0006] To achieve the above object, the utility model adopts the following technical scheme. A fabric friction testing machine includes a device main body. A test bench is fixedly installed on the device main body. A control room is provided on the test bench. A plurality of sliding tracks are fixedly installed on the test bench. A friction plate is slidably installed on the sliding tracks. A plurality of lifting rods are provided on the test bench. A sample support assembly is jointly provided among the plurality of lifting rods. The sample support assembly is distributed above the friction plate;

[0007] The sample support assembly includes a lifting frame, and a rotating frame is arranged inside the lifting frame;

[0008] A sample support plate is fixedly installed inside the rotating frame. Fastening grooves are formed at both the left and right ends of the sample support plate. A chute is formed on the inner wall surface of the fastening groove. A fastening block for fixing the fabric sample is arranged in the fastening groove.

[0009] Preferably, connecting blocks are arranged on both the left and right side wall surfaces of the lifting frame, and the connecting blocks are fixedly installed at the free ends of the lifting rods.

[0010] Preferably, the inner wall surface of the lifting frame is provided with symmetric connecting shafts on the left and right, and a rotating frame is rotatably installed inside the lifting frame through the connecting shafts.

[0011] Preferably, the side wall surface of the fastening block is provided with a slider, and the fastening block is slidably installed in the fastening groove through the cooperation of the slider and the chute.

[0012] Preferably, threaded control bolts are installed on the left and right side wall surfaces of the rotating frame in a threaded manner.

[0013] Preferably, the ends of the two threaded control bolts close to each other are rotatably connected to the fastening block.

[0014] Beneficial Effects

[0015] The utility model provides a fabric friction testing machine, which has the following beneficial effects:

[0016] (1) When using the fabric friction testing machine, first flip open the rotating frame so that the rotating frame flips away from the lifting frame. At this time, lay the fabric sample on the sample support plate, and insert the two ends of the fabric sample downward into the fastening groove. Control the rotation of the two threaded control bolts to make the threaded control bolts drive the fastening block to slide inward until the fastening block clamps and fixes the two ends of the fabric sample. At this time, the fabric sample will be fixedly attached and distributed on the sample support plate. After fixing the fabric sample, flip the entire rotating frame. After the rotating frame flips, it is distributed inside the lifting frame, and at the same time, the fabric sample is distributed facing directly downward at this time. Control the lifting frame to move downward through multiple lifting rods, and the lifting frame will drive the fabric sample to be attached to the friction plate. Through the free flipping design of the rotating frame, the fabric sample can be accurately and firmly fixed on the sample support plate, avoiding the problem of position deviation, thereby significantly improving the repeatability of the friction test and the reliability of the results.

[0017] (2) Through the design of the rotating frame, the fabric friction testing machine simplifies the installation process of the fabric sample. The entire operation process is convenient and fast, avoiding the cumbersome steps such as repeated alignment and adjustment when using a detachable support in the traditional device, thereby reducing the operation difficulty and the risk of errors.
