Description

Technical Field

[0001] The utility model relates to the technical field of textile cloth wear-resistance testing devices, in particular to a textile cloth wear-resistance testing device. Background Art

[0002] Wear resistance is an important indicator of textile product quality. It directly affects the durability, performance and appearance of the product. Wear resistance refers to the ability of fabrics to resist wear during repeated friction between fabrics or other substances. In order to control the quality of textiles, strict testing of the wear resistance of textiles is required to prevent quality problems.

[0003] At present, the main instrument for testing the wear resistance of textile fabrics is the Martindale abrasion tester. Its testing method and principle are as follows: the fabric to be tested is cut into a circular sample, and the sample is placed on the bottom through-hole ring of the compression nut. Then, the insert is placed in the compression nut and pressed on the sample. Then, the internal thread of the compression cover of the socket and the external thread on the upper part of the compression nut are tightened downward, so that the edge of the sample is pressed against the through-hole ring of the compression nut. The upper surface of the rest of the sample (the working part) is in close contact with the bottom of the insert, and the lower surface of the working part of the sample is exposed downward outside the through-hole of the compression nut, thus completing the clamping installation of the sample.

[0004] Then place the specimen and the counterweight directly below the fixture guide sleeve, pass the pin through the sleeve and insert it into the blind hole of the upper connecting shaft of the sleeve to complete the installation before the test. Start the tester, and the drive device drives the fixture guide, and drives the counterweight and the specimen through the pin shaft to perform a friction motion with a specified load on the abrasive plane of the grinding table. The motion trajectory is a Lissajous figure (from a circle to a gradually narrowing ellipse until it becomes a straight line, and then from this straight line gradually reverses to a widening ellipse until it becomes a circle). Repeat the friction motion until the specimen is damaged. The wear resistance of the specimen is measured based on the number of friction times when it is damaged.

[0005] The existing Martindale abrasion tester has no dust suction structure on the outside when in use. During the actual abrasion test, the textile fabric will generate fine dust due to wear. Although the amount of dust is not large, it will still affect the test environment and the health of the tester during a long test. Based on this, in order to realize the suction operation of fine dust, a textile fabric abrasion test device is provided. Utility Model Content

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1 to 5 In an embodiment of the present invention, a textile wear resistance testing device includes a workbench 1, a movable platform 2, and a grinding head assembly 3. The movable platform 2 includes a cover plate 201 and a through hole 204. The through hole 204 is opened at the top of the cover plate 201 and penetrates to the bottom of the cover plate 201 to provide a hole position for installing the grinding head assembly 3. The bottom end of the movable platform 2 is located outside the through hole 204 and is provided with a dust collection assembly 4. The dust collection assembly 4 is used to suck fine dust generated by wear during the test.

[0029] The dust collection assembly 4 includes a fixed screw 401 and a suction hood 402;

[0030] The fixing screw 401 is fixed to the bottom of the cover plate 201 and is distributed outside the through hole 204. The fixing screw 401 and the through hole 204 are coaxially distributed.

[0031] The suction hood 402 is threadedly connected to the outside of the fixed screw barrel 401 and fits tightly against the bottom of the cover plate 201. The suction hood 402 has a hollow structure and has a plurality of annularly distributed dust suction ports 403 at the bottom. The top of the cover plate 201 has a ventilation hole 205 that passes through the bottom of the cover plate 201 and communicates with the inner cavity of the suction hood 402. An air pipe is inserted into the ventilation hole 205 and connected to an external suction device to achieve fine dust suction operation.

[0032] The workbench 1 includes a machine base 101, a control panel 102, a grinding table 103, a support base 104, and a crank head 105;

[0033] The control panel 102 is installed at the front end of the machine base 101, the grinding table 103 and the support base 104 are installed at the top of the machine base 101, and three crank rotors 105 are provided. The three crank rotors 105 are horizontally distributed above the machine base 101, and three drive motors are installed inside the machine base 101. The output ends of the three drive motors pass through the top of the machine base 101 and are respectively connected to the three crank rotors 105.

[0034] The top of the cover plate 201 is provided with a longitudinal guide groove 202 and a transverse guide groove 203. The longitudinal guide groove 202 is distributed in the middle of the cover plate 201, and the two transverse guide grooves 203 are symmetrically distributed with the longitudinal guide groove 202 as the center. The bottom of the cover plate 201 is attached to the top of the support seat 104, and the crank protrusions on the top of the three crank heads 105 are sequentially connected to the inner sides of the transverse guide grooves 203 and the longitudinal guide groove 202.

[0035] The grinding head assembly 3 comprises a counterweight 301, a pressing rod 302, and a sample clamp 303.

[0036] The sample clamp 303 is attached to the upper surface of the grinding table 103. The pressing rod 302 penetrates through the through hole 204 from the top of the cover plate 201 and is inserted into the top of the sample clamp 303. The counterweight 301 is sleeved on the top of the pressing rod 302. The counterweight 301 and the pressing rod 302 are used to provide pressure to the sample clamp 303 to keep the sample clamp 303 attached to the grinding table 103.

[0037] In this embodiment, it should be noted that the sample clamp 303 is used to clamp and fix the textile sample, so that the textile is attached to the surface of the grinding table 103. This structure is the conventional structure of the existing Martindale abrasion tester, and will not be described here.

[0038] When using this abrasion testing device, multiple air tubes are inserted into the ventilation holes 205 to make them communicate with the inner cavity of the suction cover 402. Then the air tubes are connected to the external dust collection device. During the abrasion test, the driving motor inside the base 101 and the external dust collection device are started simultaneously. The driving motor drives the crank head 105 to rotate. Since the diameters of the longitudinal guide groove 202 and the transverse guide groove 203 are distributed in a cross shape, the cover plate 201 can form an accurate Lissajous pattern under the drive of the crank head 105. The cover plate 210 drives the grinding head assembly 3 to move, so that the relative friction between the textile sample and the grinding table 103 occurs, and then the abrasion resistance and pilling resistance of the textile sample are tested.

[0039] During this process, the external dust collection device generates suction and transmits it to the suction cover 402 through the air tube, and performs suction operation on the surrounding area above the sample clamp 303 through the dust suction port 403. In this way, when the textile sample is abraded and dust is generated, the dust can be sucked away through the channel composed of the dust suction port 403, the suction cover 402, and the air tube, thereby avoiding the dust remaining in the air and affecting the environment and the health of the test personnel.

[0040] Please refer to Figures 1 to 5 The number and position of the through hole 204 and the grinding head assembly 3 correspond to the number and position of the grinding table 103 one by one, and the number of the ventilation hole 205 and the dust collection assembly 4 matches the number of the through hole 204.

[0041] A conduit mounting groove 206 communicating with the plurality of ventilation holes 205 is further defined on the top of the cover plate 201 , and the conduit mounting groove 206 extends through the rear end of the cover plate 201 .

[0042] In this embodiment, by providing a number of dust suction assemblies 4 that matches the number of grinding head assemblies 3, the area near each sample holder 303 can be independently suctioned, thereby preventing the spread of dust. The mounting groove 206 facilitates the regular storage of the air pipe, thereby maintaining a good appearance of the entire device.

[0043] Please refer to Figures 1 to 5 The diameter of the distribution trajectory of the dust suction port 403 is larger than the outer diameter of the sample holder 303 , and the inner diameter of the fixed screw barrel 401 is larger than the diameter of the pressure rod 302 .

[0044] In this embodiment, this structure ensures that the dust collection assembly will not affect the assembly and disassembly operations of the grinding head assembly 3 , and the suction area of ​​the dust collection port 403 completely covers the sample holder 303 , thereby ensuring a good dust collection effect.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
