Description

Technical Field

[0001] This utility model relates to the field of fabric testing technology, specifically a textile fabric testing device. Background Technology

[0002] In the textile industry, fabric testing is a crucial step in ensuring product quality. It encompasses the evaluation of various aspects of the fabric, including its physical properties, chemical properties, and appearance quality. Colorfastness testing is a particularly important component, directly affecting the fabric's ability to maintain its color during use. Colorfastness refers to the fabric's ability to retain its color without fading, staining, or discoloration when subjected to various external factors such as washing, friction, light exposure, water stains, and perspiration.

[0003] According to the search, Chinese patent document CN221260626U discloses a device for testing the color fastness of textile fabrics. A friction component is installed on the inner sidewall of the top of the support frame, corresponding to the fixing component. After the fixing component secures the textile fabric to be tested, activating the friction component allows for the testing of the color fastness of the fabric. The operation is simple and efficient.

[0004] However, in actual use, the friction components of the aforementioned color fastness testing device are not easy to replace, and the color fastness is tested by directly driving the friction components with a motor to rub the fabric. This results in insufficient contact between the friction components and the fabric, leading to low accuracy of the test results. Utility Model Content

[0014] Compared with the prior art, the present invention provides a textile fabric detection device, which has the following beneficial effects:

[0015] 1. This utility model, through the eccentric connection of the pressure roller and shaft design, combined with the operation of the handle, allows for rapid pressing and releasing of the sample fabric simply by turning the handle. The operation is simple and efficient, significantly shortening the sample fixation time. At the same time, the anti-slip texture on the outer circumference of the pressure roller effectively enhances the friction between the roller and the fabric, preventing the fabric from slipping during the test and ensuring the stability of the sample position during the test.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 A textile fabric testing device includes a testing platform 1. A fixing component 2 is bolted to the side wall of the testing platform 1, and a guide rail 3 is bolted to the top surface of the testing platform 1. A slider 4 is slidably connected to the outer surface of the guide rail 3. An ear plate 5 is fixedly connected to one side of the slider 4. An ear 6 is rotatably connected to the inside of the ear plate 5 via a pin. A connecting plate 7 is fixedly connected to one end of the ear 6. A sleeve 8 is bolted to one end of the connecting plate 7. A collar 9 is fixedly connected to the outer surface of the sleeve 8, and a testing head 10 is sleeved at the bottom of the sleeve 8. A magnetic ring 11 is embedded in the top of the testing head 10. An angle plate 12 is fixedly connected to the top surface of the slider 4. A connecting rod 13 is rotatably connected to the inside of the angle plate 12 via a pin. A rotating plate 14 is rotatably connected to one end of the connecting rod 13. A reduction motor 15 and a protective shell 16 are fixedly connected to the top of the testing platform 1.

[0025] Specifically, the fixing component 2 includes a base plate 201, two side plates 202 are fixedly connected to both sides of the base plate 201, a shaft 203 is rotatably connected inside the side plate 202, a pressure roller 204 is fixedly connected to the outer surface of the shaft 203, and a handle 205 is bolted to one end of the shaft 203.

[0026] Specifically, multiple anti-slip patterns are circumferentially formed on the outer circumferential surface of the pressure roller 204 around its axis, and the pressure roller 204 is eccentrically connected to the shaft 203. One side of the base plate 201 is bolted to the side wall of the testing table 1.

[0027] The advantages are that by placing the sample fabric to be tested on the upper surface of the base plate 201, with both ends of the sample fabric below the pressure roller 204, and then turning the handle 205, the handle 205 drives the shaft 203 to rotate, which in turn drives the pressure roller 204 to rotate. Since the pressure roller 204 and the shaft 203 are eccentrically connected, the pressure roller 204 will gradually press the sample fabric during rotation, thereby fixing the sample. The multiple anti-slip textures circumferentially opened on the outer circumference of the pressure roller 204 around the axis direction can enhance the friction between the roller and the fabric, effectively preventing the fabric from slipping during the test and ensuring the stability of the test. The eccentric connection design allows the sample to be pressed and released easily by turning the handle 205, making the operation simple and convenient and improving the test efficiency.

[0028] Specifically, the detection head 10 is a hollow cylindrical structure, and white test cotton cloth is stuffed inside the detection head 10. There is a gap between the inner diameter of the detection head 10 and the outer diameter of the sleeve 8.

[0029] The advantages are that by placing the moistened white test cotton cloth on top of the detection head 10 and then connecting the detection head 10 with the sleeve 8, the sleeve 8 presses the cotton cloth downwards, while the magnetic ring 11 is attracted to the collar 9. On the one hand, during the subsequent color fastness rubbing test, the compression of the cotton cloth by the sleeve 8 allows the cotton cloth to fully contact the fabric to be tested, ensuring a tight fit between the two during the rubbing test. On the other hand, the attraction between the magnetic ring 11 and the collar 9 can stabilize the connection between the detection head 10 and the sleeve 8, preventing the detection head 10 from loosening or falling off during the test. At the same time, this connection method facilitates quick installation and removal of the detection head 10, and the operation is simple when the cotton cloth needs to be replaced, which can improve the testing efficiency.

[0030] Specifically, the geared motor 15 is located inside the protective housing 16, and the output shaft of the geared motor 15 is connected to the rotating plate 14 via a synchronous pulley and a synchronous belt.

[0031] The advantages are that the output shaft of the geared motor 15 drives the rotating plate 14 to rotate via the synchronous pulley and synchronous belt. The rotating plate 14 drives the connecting rod 13 to reciprocate. In this way, the connecting rod 13 pulls the angle plate 12 to make the slider 4 slide back and forth along the guide rail 3. At the same time, with the cooperation of the ear plate 5 and the connecting ear 6, the connecting plate 7 drives the sleeve 8 and the detection head 10 to reciprocate, realizing the friction between the white test cotton cloth inside the detection head 10 and the sample fabric. Finally, the color fastness of the fabric is judged by observing the staining on the white test cotton cloth. A controller is also installed on the top of the detection table 1 to control the rotation time of the geared motor 15.

[0032] Specifically, the top of the testing platform 1 is fixedly connected to two side blocks 17, and a columnar grid 18 is rotatably connected between the two side blocks 17. A limit block 19 is fixedly connected to the inner side of one of the side blocks 17, and a knob 20 is fixedly connected to one end of the columnar grid 18.

[0033] The advantages are as follows: Before testing, rotating the knob 20 clockwise causes the cylindrical barrier 18 to rotate, which lifts the connecting plate 7 by the baffle on the outer periphery of the cylindrical barrier 18. At this time, the baffle of the cylindrical barrier 18 just contacts the limiting block 19, keeping it fixed. This allows the detection head 10 to be raised, thus avoiding contact with the fabric. After the fabric sample is fixed and the white test cotton cloth is also fixed inside the detection head 10, rotating the knob 20 counterclockwise causes the cylindrical barrier 18 to rotate counterclockwise. This way, the baffle of the cylindrical barrier 18 no longer contacts the connecting plate 7, and the cotton cloth inside the detection head 10 just contacts the fabric to be tested. This allows for precise control of the timing and state of contact between the detection head 10 and the fabric, ensuring that the cotton cloth and the fabric are in the optimal contact position at the start of testing. It avoids affecting the preparation work due to premature contact and inaccurate test results due to improper contact, effectively improving the convenience of the testing operation and the reliability of the test results.

[0034] In use, first, place the sample fabric to be tested on the upper surface of the base plate 201 of the fixing component 2, so that both ends of the sample fabric are below the pressure rollers 204. Then, turn the handle 205, which drives the eccentrically connected pressure rollers 204 to rotate through the shaft 203, gradually pressing the sample fabric. The anti-slip texture on the outer circumference of the pressure rollers 204 enhances the friction, thus fixing the sample. Next, place the wetted white test cotton cloth on top of the detection head 10, and align the detection head 10 with the sleeve 8. The sleeve 8 presses the cotton cloth downwards, while the magnetic ring 11 is attracted to the collar 9, achieving a stable connection between the detection head 10 and the sleeve 8, thus completing the installation of the detection head 10 and fixing the cotton cloth. Afterward, before testing, ensure that the columnar baffle 18 is in the state of raising the detection head 10 (by turning the knob 20 clockwise to make the baffle...). (Lift the connecting plate 7 and fix it in contact with the limiting block 19). After the sample and cotton cloth are ready, turn the knob 20 counterclockwise to disengage the baffle of the cylindrical baffle 18 from the connecting plate 7, so that the cotton cloth inside the detection head 10 just contacts the fabric to be tested. Then, start the reduction motor 15 through the controller on the top of the detection platform 1. Its output shaft drives the rotating plate 14 to rotate through the synchronous wheel and synchronous belt. The rotating plate 14 drives the connecting rod 13 to reciprocate, which in turn pulls the corner plate 12 to make the slider 4 slide back and forth along the guide rail 3. At the same time, with the cooperation of the ear plate 5 and the ear 6, the connecting plate 7 drives the sleeve 8 and the detection head 10 to reciprocate, realizing the friction detection between the cotton cloth and the sample fabric. Finally, after the test is completed, turn off the reduction motor 15, remove the detection head 10, observe the staining on the white test cotton cloth, and judge the color fastness of the fabric.
