Description

Technical Field

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

[0002] Color fastness testing is a crucial step in textile quality control. Through testing, it ensures that the product retains its color well during use, reducing the risk of fading and discoloration, thereby improving the overall quality of the product. Fabric rubbing fastness testing involves fixing a standard white cotton cloth to a rubbing block, rubbing the dyed fabric according to regulations, and then evaluating the degree of staining on the white cloth under standard light.

[0003] Chinese invention patent CN117309748B discloses a "Color Fastness Testing Device for Textile Fabrics," belonging to the field of color fastness testing equipment for textile fabrics. It includes a worktable, a testing base, a power unit, and at least two sets of testing components. The testing base is fixed to the upper end of the worktable. The testing components include a fixing unit and a pressure unit. The fixing unit is detachably fixed to the upper end of the worktable, and the pressure unit is also fixed to the upper end of the worktable. The pressure unit has a friction head that slides along the length of the fixing unit. The power unit is fixed to the worktable. This invention uses a detachable fixing unit to fix the fabric, enabling rapid clamping of the fixing unit and improving the fabric testing efficiency. Simultaneously, the power unit drives the friction head to slide alternately, making the movement of the power unit and the friction head more balanced, avoiding vibration of the friction head, and ensuring the accuracy of color fastness testing.

[0004] However, in the aforementioned patent, although the friction head can slide along the fixed unit, when the fabric to be tested is fixed on the fixed end, the friction head is always above the fixed end, which makes the fabric fixing inconvenient and results in relatively low testing efficiency. Therefore, this utility model proposes a fabric color fastness testing device to solve the above problems. Utility Model Content

It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

Unless otherwise specified, the methods in the following embodiments are conventional methods in the field. Unless otherwise specified, the components or equipment in the following embodiments are general standard parts or components known to those skilled in the art, and their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In the following detailed description, many specific details are set forth to facilitate explanation and provide a comprehensive understanding of the embodiments of the present invention. However, one or more embodiments may be practiced by those skilled in the art without these specific details.

[0025] like Figures 1-3 As shown, a fabric color fastness testing device is characterized by: including a testing platform 1, a friction platform 2 fixedly connected to the top left end of the testing platform 1, a fixing mechanism on the top of the friction platform 2, a sliding mechanism on the top right side of the testing platform 1, a base 3 fixedly connected to the top of the sliding mechanism, a friction mechanism on the top of the base 3, and a positioning mechanism threaded to the center of the front end of the friction mechanism on the top of the base 3.

[0026] In the above technical solution, by setting a sliding mechanism and fixing the base 3 on the top of the sliding mechanism, the friction mechanism is set on the top of the base 3. By loosening the abutment positioning between the positioning mechanism and the base 3, the base 3 can be moved, which in turn can drive the friction unit to move over the top of the friction table 2, making it easier for the fixing mechanism to fix the fabric and improving the detection efficiency.

[0027] In this utility model, the fixing mechanism includes a set of V-shaped grooves 4, which are formed on both sides of the top of the friction table 2. A set of limiting posts 5 are fixedly connected in each set of V-shaped grooves 4. A V-shaped pressure plate 6 is raised and lowered on each set of limiting posts 5 in the same V-shaped groove 4. The volume of the V-shaped pressure plate is smaller than the volume of the V-shaped groove 4. The V-shaped pressure plates 6 are fixedly connected to each other by a set of connecting plates 7. A first threaded rod 8 is threadedly connected to the connecting plate 7. A first turntable 9 is provided on the top of the first threaded rod 8. The bottom of the first threaded rod 8 is rotatably connected to the top surface of the friction table 2.

[0028] In the above technical solution, by opening a V-groove 4 on the friction table 2 and raising and lowering a V-shaped pressure plate 6 on the limiting post 5 in the V-groove 4, after the fabric is placed on the friction table 2, turning the first turntable 9 can drive the first threaded rod 8 to rotate, so that the V-shaped pressure plate 6 can move into the V-groove 4 to press down both ends of the fabric. On the one hand, the fabric is fixed, and on the other hand, by utilizing the cooperation between the V-shaped pressure plate 6 and the V-groove 4, when the fabric is pressed down, the V-shaped pressure plate 6 is located inside the V-groove 4, which will not block the translation of the friction block 26, thus providing convenience for the translation of the friction mechanism.

[0029] In this utility model, the sliding mechanism includes a set of slide rails 10, and each set of slide rails 10 is slidably connected to a slide table 11 at its top. The base 3 is fixedly connected to the top of the slide table 11.

[0030] In the above technical solution, by fixing the slide rail 10 to the detection table 1 and sliding the slide table 11 on the slide rail 10, and installing the base 3 on the slide table 11, the base 3 and the detection table 1 slide together, providing a prerequisite for the translation of the friction mechanism.

[0031] In this utility model, the friction mechanism includes a driving unit, a driven unit, and a friction unit. The driving unit includes a set of support plates 12, which are fixedly connected to the top right side of the base 3. A rotating shaft 13 is rotatably connected to the set of support plates 12. Several cams 14 are equidistantly arranged on the rotating shaft 13, and the cams 14 are all located between the set of support plates 12. A mounting platform 15 is provided at the rear end of the set of support plates 12 on the base 3. A motor 16 is mounted on the top of the mounting platform 15, and the output shaft of the motor 16 is connected to the rotating shaft 13.

[0032] In the above technical solution, by setting a motor 16, the rotation of the motor 16 can drive the rotating shaft 13 to rotate, thereby driving the rotation of each cam 14 on the rotating shaft 13.

[0033] In this utility model, the driven unit includes a driven platform 17, the top of which is provided with a plurality of sliding grooves 18, and a slider 19 is slidably disposed in each of the sliding grooves 18. The right end of the slider 19 is provided with an abutment rod 20, which is telescopically engaged with the right side wall of the sliding groove 18. The right end of the abutment rod 20 abuts against the cam 14. The left end of the slider 19 is fixedly connected with a spring 21, and the other end of the spring 21 abuts against the left inner wall of the sliding groove 18.

[0034] In the above technical solution, a slider 19 is slidably connected in the slide groove 18, and a spring 21 is set between the left end of the slider 19 and the left side wall of the slide groove 18. With the abutting rod 20 set at the right end of the slider 19 and the cam 14 abutting each other, when the cam 14 rotates, it can generate a pushing force on the abutting rod 20, forcing the slider 19 to move left and right in the slide groove 18 under the action of the spring 21 and the abutting rod 20.

[0035] In this utility model, the friction unit includes a groove 22, which is provided on the top of the slider 19. A mounting plate 24 is fixedly connected to the groove 22 by bolts 23. A second threaded rod 25 is threadedly connected to the left end of the mounting plate 24. A friction block 26 is fixedly connected to the bottom of the second threaded rod 25. A second turntable 27 is provided on the top of the second threaded rod 25.

[0036] In the above technical solution, by opening a groove 22 on the top of the slider 19 and fixing the mounting plate 24 in the groove 22 with bolts 23, the friction force generated by the friction block 26 during the friction process can prevent the mounting plate 24 from shifting in the slider 19, thus ensuring the normal and orderly progress of the friction and improving the accuracy of the detection. By connecting the friction block 26 to the bottom of the second threaded rod 25, rotating the second turntable 27 can be used to adjust the horizontal height of the friction block 26, which is convenient for rubbing fabrics of different thicknesses.

[0037] In this utility model, the positioning mechanism includes a positioning screw 28, which is threadedly connected to the front end of the friction mechanism on the base 3. The bottom of the positioning screw 28 is provided with an anti-slip plate 29, and the top of the positioning screw 28 is fixedly connected to a third turntable 30.

[0038] In the above technical solution, by setting the anti-slip plate 29 and the positioning screw 28, rotating the third turntable 30 can drive the positioning screw 28 to rotate, which can drive the anti-slip plate 29 to rise and fall, thereby fixing the sliding position of the base 3, which facilitates the positioning and release of the entire friction mechanism, and facilitates the pressing and fixing of the fabric.

[0039] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
