DETAILED DESCRIPTION

[0033] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0034] As attached Figure 1 As shown, a fabric friction resistance color fastness rapid testing machine includes a frame 1, the frame 1 is equipped with a vertical pressure mechanism and a power output mechanism, and a friction plate 6 is provided in the common connection working area between the output end of the power output mechanism and the vertical pressure mechanism, and can move in the XY axis direction under the driving action of the power output mechanism. The frame 1 is laterally movable to support the fabric 2 to be tested, wherein the fabric 2 to be tested is placed on the lower side of the vertical pressure mechanism and the upper side of the friction plate 6, and is laterally penetrated to the outside, and the friction test is realized by the movement of the friction plate 6 and the static state of the vertical pressure head.

[0035] See attached Figure 1-2 As shown, the power output mechanism includes a longitudinal arrangement (relative to the adjacent Figure 1 The electric push rod 4 is fixed to the bottom surface of the frame 1, and its output end is connected to the conductive plate 5, and the conductive plate 5 is hinged with a rotating rod 9 on the side, and a moving seat 10 is hinged at the far end of the rotating rod 9. The moving seat 10 is synchronously driven by the running of the conductive plate 5 through the rotating rod 9 to achieve its relative horizontal movement.

[0036] In order to limit the horizontal movement trajectory of the moving seat 10, a horizontal long groove 14 is opened in the X-axis direction, and a slider 17 is connected to the bottom of the moving seat 10, and the slider 17 is slidably connected to the horizontal long groove 14. A guide rod 11 is longitudinally installed on the bottom surface of the inner part of the frame 1. A plurality of guide rods 11 are arranged at intervals, and can fit the conductive plates 5 at different conductive positions, so as to always limit their stable movement along the Y-axis trajectory. In this embodiment, the moving seat 10 and the conductive plate 5 need to drive the friction plate 6 to move separately, that is, when the two move, only one of them can be connected to the friction plate 6 and the other can be disconnected, and the two need to be able to connect and disconnect at any time to prevent the direction of each from being blocked and causing overall stagnation.

[0037] See attached Figure 2 As shown, in order to realize the quick connection and disconnection of the moving seat 10 and the conducting plate 5 with the friction plate 6 respectively, the structure of electromagnet and permanent magnet is adopted. By installing electromagnets on the moving seat 10 and the conducting plate 5, one of the electromagnets is energized to drive the friction plate 6 to move horizontally or vertically. Specifically, electromagnet 1 is installed on the upper side of the moving seat 10, and the friction plate 6 is connected to permanent magnet 1 8 by extending in the relative lateral direction; electromagnet 2 13 is installed on the lower side of the front end of the conducting plate 5, and the corresponding upper side of the friction plate 6 is connected to permanent magnet 2 7. The advantage of this setting is that it can be connected and disconnected respectively during movement, and can be flexibly controlled according to needs. Secondly, although the moving seat 10 and the conducting plate 5 belong to synchronous movement in this design, driving them alone will not affect the friction plate 6.

[0038] Considering that the rotating rod 9 will be blocked by the friction plate 6 during the rotation process, a notch is provided at the bottom of the friction plate 6 to accommodate the rotation trajectory of the rotating rod 9 .

[0039] See attached Figure 3 As shown, the vertical pressure mechanism includes a power source 16, and the output end of the power source 16 is horizontally connected to a plurality of long rods 15 at intervals, the long rods 15 extend above the fabric 2 to be tested, and a plurality of mounting positions are provided on the lower side of the long rods 15 to accommodate the corresponding number and detection points, and the mounting positions are movably connected to the vertical pressure head 12.

[0040] When multiple test points are tested simultaneously, the force and position of the downward pressing head 12 that applies force need to be kept consistent in order to obtain relatively accurate test data. Therefore, the power source 16 is a substrate 162, a cylinder 163, and a base 161. The long rod 15 is horizontally connected to the substrate 162 at intervals. The two sides of the base 161 and the two sides of the substrate 162 are respectively hinged with rod 1 165 and rod 2 166. Rod 1 165 and rod 2 166 are hinged to each other. The cylinder 163 is horizontally placed between rod 1 165 and rod 2 166, and the two ends are respectively connected to the inner side of rod 1 165 or rod 2 166. Secondly, a support rod 164 is set at the bottom of the cylinder 163 to achieve stable support. The cylinder 163 drives rod 1 165 and rod 2 166 to rotate synchronously to achieve the rise and fall of the upper substrate 162.

[0041] See attached Figure 6 As shown, a sleeve 20 is installed on the upper side of the vertical pressure head 12, and a clamp 21 is connected to the corresponding lower side of the long rod 15. The sleeve 20 can realize flexible installation of the vertical pressure head 12 and the long rod 15 by threaded connection or clamping.

[0042] In summary, considering that the fabric 2 to be tested needs to be kept relatively fixed and unaffected during the test, clamping members 3 are respectively provided on both sides of the fabric 2 to be tested away from the test area (i.e., the friction plate 6 area) to clamp the fabric 2 to be tested in a horizontal state. Because the fabric 2 to be tested as a whole only needs to be kept relatively still during the test, there is basically no need to set a strict fixed clamping structure like the existing equipment, that is, the clamping member 3 of this solution can adopt a relatively conventional structure.

[0043] The clamping member 3 includes a bracket 22, on which two adjacent clamping guide rollers 18 are pivotally connected, wherein the clamping guide rollers 18 need to fit tightly to keep the tested fabric 2 from twisting and deforming at its unrolling position when receiving external force.

[0044] The dry friction color fastness test is to evaluate the color fastness of fabrics in a dry state by simulating the friction conditions of fabrics in daily use. During the test, the fabric 2 to be tested is rubbed with white cotton cloth (placed on the friction plate), and then the color is compared with the gray card colorimetric card, and the color fastness grade is evaluated according to the size of the color difference. During the specific test, the friction plate 6 is rubbed back and forth 10 times along a stroke of 100mm on the sample, and each reciprocating time is 1 second. The downward pressure of the friction head is 9N, and the longitudinal and transverse directions of the fabric 2 to be tested are tested respectively.

[0045] The above design is for the dry friction color fastness test. This solution adds a wet friction color fastness test on the original frame 1 to achieve the simultaneous use of the two tests. Wet friction color fastness test: Similar to the dry friction color fastness test, the wet friction color fastness test is to rub the fabric in a wet state to evaluate the color fastness of the fabric in a wet state. The test method is similar to the dry friction color fastness test, except that the fabric sample needs to be soaked in water during the test and then the friction test is performed.

[0046] For details, see the attached Figure 5 , 7As shown in Figure 9, a test frame 19 is provided at the end of the fabric 2 to be tested, and a tank box 23 is provided in the test frame 19, wherein the tank box 23 is filled with water and the water level is higher than the fabric 2 to be tested. The test method is that the friction iron ball 27 attached to the upper side of the fabric 2 to be tested is subjected to friction rotation relative to the static fabric 2 to be tested, so as to realize the friction test. Specifically, a rotating seat 26 is provided at the bottom of the tank box 23, and a circumferential guide platform 28 is installed on the rotating seat 26, and the guide platform 28 is designed with a permanent magnet material. A cover body 24 is provided on the upper side of the tank box 23, and the bottom of the cover body 24 is designed with an electromagnet. Under normal conditions, the friction iron ball 27 is adsorbed on the lower side of the cover body 24, and there is a certain gap with the guide platform 28 for the fabric 2 to be tested to pass through. After the fabric 2 to be tested passes above the rotating seat 26, the electromagnet on the lower side of the cover body 24 is powered off, so that the friction iron ball 27 falls and is adsorbed and arranged on the guide platform 28. After the test is completed, the electromagnet at the bottom of the cover body 24 can be energized to attract the friction iron ball 27 away from the guide platform 28 for next use.

[0047] Secondly, a pressing block 25 matching the shape of the side wall of the tank box 23 is provided on one side of the cover body 24, which is clamped and pressed after the fabric 2 to be tested is introduced, and cooperates with the outer clamping piece 3 to fix the immersed fabric 2 to be tested.

[0048] It should be noted that the fabric 2 to be tested immersed in the tank 23 may have a relatively larger surplus to reduce the influence of the pulling force on both sides.

[0049] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
