Description

Technical Field

[0001] The present invention relates to the technical field of textile color fastness auxiliary detection, in particular to a textile color fastness detection device. Background Art

[0002] Fabric is an essential component of textile production. However, to prevent discoloration during subsequent use, fabric color fastness testing is often performed during the production process. Among the many color fastness tests, the most commonly used include washfastness, lightfastness, and rubbing fastness.

[0003] When performing friction testing, the shape of the tester's workbench (whether flat or curved) will affect the test results. A flat workbench is suitable for most general tests, facilitating even pressure application and controlled friction direction. Conversely, a curved workbench mimics the curved surface of certain textiles in actual wear. This design better simulates the friction experienced by the human body. While a curved workbench may result in uneven pressure distribution across different areas of the friction head, this is closer to actual wear conditions, resulting in test results that are more realistic.

[0004] However, traditional workbenches are generally fixed structures that can only meet the requirements of a single working shape and cannot adapt to multiple testing needs. This means that different types of color fastness tests require different equipment to be used for each test. This situation not only increases the cost of equipment procurement and maintenance, but also prolongs the overall testing process. Each equipment change requires recalibration and resetting, which undoubtedly increases the time and complexity of the operation. In addition, due to the possible differences in design and standards between different equipment, even when performing the same type of test, inconsistent test data may be caused.

[0005] Based on this, in order to solve the above-mentioned technical defects, a color fastness testing device for textiles is proposed. Summary of the Invention

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0034] Example 1: A color fastness testing device for textiles, such as Figures 1-6 As shown, it includes a base plate 1, a workbench 101, a connecting block 102, an adjusting block 103, an elastic support platform 104, a fixing component, an adjusting component and a detecting component. The workbench 101 is connected to the left side of the top of the base plate 1, and the connecting blocks 102 are symmetrically connected to the top of the workbench 101. The inner sides of the connecting blocks 102 are slidably connected to the adjusting blocks 103. The elastic support platforms 104 are connected between the adjusting blocks 103. The elastic support platforms 104 are made of spring steel and are known for their excellent elastic properties and fatigue resistance. They can withstand repeated stress and are not prone to permanent deformation. The workbench 101 is provided with an adjusting component, the base plate 1 is provided with a detecting component, and the connecting block 102 is provided with a fixing component for fixing the textile to be tested.

[0035] like Figure 1-Figure 3 As shown, the fixed assembly includes a sliding block 105, a screw 106, a pressure plate 107 and a return spring 108. The sliding block 105 is slidably connected to the top of the connecting block 102 on the left, and the sliding block 105 is fixedly connected to the top of the connecting block 102 on the right. Reset springs 108 are connected between the front and rear sides of the sliding block 105 on the left and the inside of the connecting block 102 on the left. The two connecting blocks 102 are slidably connected with a pressure plate 107 for pressing the textile to be tested. The tops of the two connecting blocks 102 are threadedly connected with the screw 106, and the bottoms of the screw 106 are rotatably connected to the pressure plate 107 on the same side.

[0036] like Figure 1 、 Figure 4 and Figure 5 As shown, the adjustment assembly includes a fixed frame 201, a drive motor 202, a semi-circular disc 203, an adjusting rod 204, a transmission shaft 205, a hinged plate 206 and a connecting piece 207. The fixed frame 201 is symmetrically connected to the bottom of the workbench 101 front and back, and the semi-circular disc 203 is rotatably connected to the inner side of the fixed frame 201. The drive motor 202 is installed on the front fixed frame 201 by bolts, and the output shaft of the drive motor 202 is connected to the semi-circular disc 203 on the front side. The transmission shaft 205 is connected between the upper sides of the two semi-circular discs 203, and the hinged plate 206 is rotatably connected to the transmission shaft 205. Connecting pieces 207 are symmetrically welded to the middle of the bottom of the elastic support platform 104 front and back. The upper end of the hinged plate 206 is rotatably connected to the two connecting pieces 207. The adjusting rod 204 is symmetrically connected to the sliding block 105 on the left side by bolts, and the transmission shaft 205 is in contact with the adjusting rod 204.

[0037] like Figure 1 、 Figure 4 and Figure 6As shown, the detection assembly includes a guide frame 301, a sliding frame 302, a rotating plate 303, a torsion spring 304, a die head 305, a support frame 306, a servo motor 307, a rotating rod 308 and a push rod 309. The right side of the top of the bottom plate 1 is connected to the guide frame 301 by bolts, the sliding frame 302 is slidably connected to the guide frame 301, the sliding frame 302 is rotatably connected to the rotating plate 303, two torsion springs 304 are connected between the rotating plate 303 and the sliding frame 302, and the left side of the rotating plate 303 is rotatably connected to the rotating plate 303. It is connected to the die head 305, and the top of the base plate 1 is located at the rear side of the guide frame 301 and is connected to the support frame 306. The servo motor 307 is installed on the upper side of the support frame 306 by bolts. The output shaft of the servo motor 307 is connected to the rotating rod 308, and the right end of the rotating rod 308 is connected to the pushing rod 309. The left end of the pushing rod 309 is rotatably connected to the sliding frame 302. The length of the pushing rod 309 is longer than that of the rotating rod 308, and the rotation circumference of the two is different. The rotation of the rotating rod 308 can drive the pushing rod 309 to move left and right repeatedly.

[0038] When testing the color fastness of textiles, the servo motor 307 is first connected to the tester. The tester can adjust the speed of the servo motor 307. A test sample is cut to a certain size according to standard requirements, and a white friction cloth is prepared as a medium to receive color transfer. Sandpaper is placed under the test sample, and the test sample is placed flat on the elastic support table 104. The test sample and the ends of the sandpaper pass through the sliding block 105 and are located under the pressure plate 107. After ensuring that the sample is flat and wrinkle-free, the screw 106 is rotated. The screw 106 moves downward, driving the pressure plate 107 downward, pressing the ends of the test sample together. After the sample is fixed, the rotating plate 303 is lifted upward, causing the torsion spring 1 304 to deform. At this time, the rotating plate 303 drives the die head 305 upward to fix the white cloth on the die head 305. After the fixation is complete, the rotating plate 303 is released, causing the torsion spring 1 304 to rebound and reset, driving the rotating plate 303 and the die head 305 to move downward and reset, so that the die head 305 and the white cloth are tightly attached to the surface of the test sample on the elastic support platform 104. Next, the tester is operated to control the speed of the servo motor 307 and start the servo motor 307. The rotation of the output shaft of the servo motor 307 drives the rotating rod 308 to rotate, which in turn drives the push rod 309 to rotate. Because the push rod 309 is longer than the rotating rod 308, within a certain rotation angle, the rotating rod 308 causes the push rod 309 to push the sliding frame 302 to the left along the guide frame 301, driving the rotating plate 303 and the die head 305 to move to the left, causing the die head 305 to rub the white cloth against the test sample. In the initial state, the elastic support platform 104 is in an arc state. The die head 305 is rotatably connected to the connecting plate. As the die head 305 moves, the downward pressure of the torsion spring 304 causes the bottom surface of the die head 305 to contact the test sample on the elastic support platform 104. The die head 305 rotates with the curvature of the elastic support platform 104, maintaining the bottom surface of the die head 305 in contact with the elastic support platform 104. As the rotating rod 308 continues to rotate, the push rod 309 rotates and moves left and right, pulling the sliding frame 302 to move back and forth, causing the die head 305 to move back and forth repeatedly, rubbing the sample with a certain pressure, speed, and a specified number of times. The white cloth can be dry or wet, depending on the actual use conditions to be simulated. After the friction is completed, the servo motor 307 is turned off, the white cloth is removed from the die head 305, and the cloth is compared to a standard rating card to assess the degree of color transfer. The rating is generally from 1 to 5, with 5 indicating no color transfer and 1 indicating severe color transfer.

[0039] In order to simulate different actual usage conditions or conduct more accurate tests on specific types of textiles, this can be achieved by changing the shape of the elastic support platform 104. In the initial state, the elastic support platform 104 is in an arc state. After the test is completed, if the elastic support platform 104 needs to be changed to a flat state, the drive motor 202 can be started. The output shaft of the drive motor 202 rotates, driving the front semi-circular disk 203 to rotate, and then drives the transmission shaft 205 and the rear semi-circular disk 203 to rotate. The rotation of the transmission shaft 205 drives the hinge plate 206 to rotate, pulling the hinge plate 206 downward, causing the hinge plate 206 to pull the connecting member 207 downward. The connecting member 207 pulls the middle of the elastic support platform 104 downward and flattens it, causing the two ends of the elastic support platform 104 to extend outward under the thrust, pushing the adjustment block 103 outward. When the transmission shaft 205 rotates with the semi-circular disk 203 and contacts the adjustment rod 204, it pushes the adjustment rod 204 to the left, which in turn drives the left sliding block 105 to move leftward, compressing the return spring 108. The left sliding block 105 drives the pressure plate 107 and screw 106 on it to move leftward, thereby pulling the left end of the test sample to extend leftward, allowing the sample and the sandpaper underneath it to adapt to the changing shape of the elastic support platform 104. The sample is pulled to the left and becomes horizontal against the elastic support platform 104. After the elastic support platform 104 is adjusted to a horizontal state, the drive motor 202 automatically turns off, and then the above-mentioned operating steps can be repeated to carry out a friction test of the sample in the curved state of the elastic support platform 104. If it is necessary to adjust the elastic support platform 104 back to the curved state, the above-mentioned steps are reversed to control the drive motor 202 to run in reverse. After returning to the initial state, the drive motor 202 will automatically turn off. The transmission shaft 205 will reverse and reset along with the semi-disc 203 and disengage from the adjusting rod 204. The reset spring 108 will rebound and reset, pushing the sliding block 105 on the left to move to the right and reset. The middle part of the elastic support platform 104 is pushed up in the shape of a curved surface, and the sliding block 105 on the left drives the left end of the sample to move to the right to adapt to the curved surface of the elastic support platform 104 and complete the shape adjustment.

[0040] Example 2: Based on Example 1, Figure 7 and Figure 8As shown, it also includes a connecting rod 501, a sliding rod 502, a guide block 503, a support rod 504, a pulley 505 and a buffer spring 506. The left end of the rotating plate 303 is symmetrically connected to the connecting rod 501 in a front-to-back rotational manner. The connecting rod 501 is connected to the die head 305. The sliding rod 502 is slidably connected to the connecting rod 501. The lower end of the sliding rod 502 is connected to the guide block 503. The two guide blocks 503 are limited to the front and rear sides of the elastic support platform 104. The support rod 504 is symmetrically slidably connected to the upper and lower sides of the guide block 503. A buffer spring 506 is connected between the support rod 504 and the guide block 503. The pulley 505 is rotatably connected to the support rod 504, and the pulleys 505 on the upper and lower sides are respectively attached to the upper and lower walls of the elastic support platform 104.

[0041] Pulleys 505 adhere to the upper and lower sidewalls of the elastic support platform 104, assisting the sliding of the die head 305 as it moves left and right. Buffer springs 506 act as a buffer, allowing the pulleys 505 to adapt to the curved surface of the elastic support platform 104. The sliding rod 502 slides along the connecting rod 501. The mutual restraint between the guide block 503, the sliding rod 502, and the connecting rod 501 ensures that the bottom surface of the die head 305 remains in contact with the elastic support platform 104 during movement. When the elastic support platform 104 is in the curved state, test accuracy is guaranteed. When the rotating plate 303 and die head 305 are lifted upward, the sliding movement of the connecting rod 501 on the sliding rod 502 ensures that the rotating plate 303 and die head 305 are not obstructed. Similarly, when the elastic support platform 104 is adjusted to a flat surface, the sliding arrangement between the connecting rod 501 and the sliding rod 502 also ensures that the test proceeds normally.

[0042] like Figure 9 、 Figure 10 and Figure 11 As shown, it also includes a baffle 401, a support member 402, a fixed block 403 and a compression spring 404. The baffle 401 is connected between the right sides of the two sliding rods 502, and the support member 402 is connected to the upper side of the die head 305. A fixed block 403 for fixing the white cloth is slidably connected to the support member 402. The fixed block 403 is slidably connected to the die head 305, and the fixed block 403 is in contact with the baffle 401. Compression springs 404 are connected between the front and rear sides of the fixed block 403 and the support member 402. A through-connection groove 405 is provided at the bottom inner side of the fixed block 403, and the through-connection groove 405 is slidably matched with the die head 305.

[0043] To secure the friction cloth to the die head 305, first lift the rotating plate 303 upward, moving the die head 305 upward. At this point, the support member 402 and the fixed block 403 also move upward until the fixed block 403 contacts the stopper 401. The stopper 401 is connected to the sliding rod 502. When the stopper 401 blocks the fixed block 403, the die head 305 and the support member 402 continue to move upward, compressing the compression spring 404 and disengaging the die head 305 from the threading slot 405. At this point, the cloth is placed into the fixed block 403, covering the threading slot 405. The rotating plate 303 is then released, allowing the rotating plate 303 and the die head 305 to move downward and reset. The compression spring 404 rebounds and resets, causing the fixed block 403 to return to its original position and disengage from the stopper 401. The die head 305 contacts the cloth and pushes the center of the cloth downward from the threading groove 405, causing the cloth to wrap around the lower end of the die head 305. The rest of the cloth is clamped between the die head 305 and the threading groove 405, automatically securing the cloth. This design provides convenience for workers, eliminating the need for other securing methods. To remove the cloth, repeat the above steps to disengage the die head 305 from the threading groove 405, thereby releasing the cloth.

[0044] like Figure 12 and Figure 13 As shown, it also includes a support block 601, a rotating rod 602, a push rod 603, a second torsion spring 604 and a stopper 605. The support block 601 is welded on the right side of the connecting block 102 on the right side. The rotating rod 602 is rotatably connected to the support block 601. The push rod 603 is connected to the rear side of the rotating rod 602. Two second torsion springs 604 are connected between the push rod 603 and the support block 601. The second torsion spring 604 is sleeved on the rotating rod 602. A stopper 605 is welded on the right side of the top of the support block 601. The push rod 603 contacts and cooperates with the stopper 605, and the push rod 603 contacts and cooperates with the rotating plate 303. The lower end of the push rod 603 is inclined, which fits the curvature of the bottom surface of the rotating plate 303 to resist the rotating plate 303 and keep it in a lifted state.

[0045] When the cam 603 is in the state of being tilted, the cam 603 is pressed against the push rod 603 by the force of the gravity of the cam 603, so that the cam 603 and the die head 305 are kept in the state of being lifted, which is convenient for the staff to fix and remove the cam 603, and the staff does not need to hold the cam 603 all the time. After the operation is completed, the cam 603 is slightly lifted up so that it no longer presses the push rod 603, and the cam 603 rebounds and resets, driving the cam 602 and the push rod 603 to reverse and reset, and then releasing the cam 603 so that the cam 603 and the die head 305 are automatically reset.

[0046] like Figure 1 As shown, a hot air blower 7 is also included. The hot air blower 7 is symmetrically installed on the top of the sliding block 105. When performing wet friction testing, the fabric being tested is wetted by the white cloth. The hot air blower 7 can be started as needed to dry the fabric.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
