Detailed implementation manners

[0027] The following describes in detail a high-efficiency color fastness detection device for textiles provided by the present utility model in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments adopt the best and preferred embodiments. For some well-known technologies, those skilled in the art can also adopt other alternative ways to implement them; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present utility model.

[0028] Such as Figure 1 - Figure 5As shown in the figure, an embodiment of the utility model provides an efficient color fastness detection device based on textiles, which includes a pressing component 3. The pressing component 3 includes a polished rod 32 and a movable sleeve 35 slidably connected to the polished rod 32. One end of the movable sleeve 35 is provided with a top cap 36 for installing a test white cloth. The end of the polished rod 32 away from the movable sleeve 35 is driven by an electro-hydraulic push rod 2; a spring 7 is located inside the movable sleeve 35 and is configured to be squeezed by the polished rod 32 and the top cap 36 during the friction test of the fabric; a rotating friction component 5 is driven to rotate by a motor 4. The rotating friction component 5 includes a rotating disk 51 connected to the output end of the motor 4, an inner cavity 53 is formed inside, and a boss 54 movably connected in cooperation with the rotating disk 51 for installing a test fabric. The end face of the boss 54 and the end face of the top cap 36 on the side away from the movable sleeve 35 are relatively parallel, ensuring that the test fabric and the test white cloth are closely attached during the test. The output ends of the motor 4 and the electro-hydraulic push rod 2 are relatively arranged, and the central extension line of the output direction of the electro-hydraulic push rod 2 is collinear with the output rotation central axis of the motor 4; a pressure sensor 8 is located on the side of the inner cavity 53 away from the boss 54, and there are multiple pressure sensors 8. The pressure sensors 8 are configured to be squeezed by the boss 54 during the friction test of the fabric. Among them, the pressure sensor 8 is electrically connected to the electro-hydraulic push rod 2 through a control module. The pressure sensor 8 adopts a piezoresistive sensor. When the metal block of the sensor probe is pressed, its own resistance changes regularly with the pressure. By inputting a rated value in the control module and comparing the pressure value detected by the pressure sensor 8 with the rated value, the advancement and retraction of the voltage push rod are controlled. When the detected actual pressure value is greater than the rated value, the control module controls the output end of the electro-hydraulic push rod 2 to retract. On the contrary, it controls it to extend until the actual value detected by the pressure sensor 8 is equal to the rated value. Further, during the rotating friction test, dynamic control is performed through the above method, so that the test white cloth and the test fabric are always under the action of a rated pressure during the friction test.

[0029] By setting the pressing component 3 to push and cooperate with the rotating friction component 5 to squeeze the test fabric and the test white cloth, while the rotating friction component 5 drives the test fabric to rotate, the pressing component 3 applies a constant pressure to the closely attached test fabric and test white cloth under the elastic force of the spring 7, making the friction force between the two constant, ensuring the variable control during the fabric test. When testing fabrics of different thicknesses, the friction force is constant, ensuring the test accuracy.

[0030] As Figure 1 shown, it further includes a workbench 1. The electro-hydraulic push rod 2 and the motor 4 are both fixedly connected to the top of the workbench 1 through a mounting table.

[0031] Through this setting, the relative fixation of the electro-hydraulic push rod 2 and the motor 4 is ensured.

[0032] As Figure 2As shown, one end of the polished rod 32 away from the movable sleeve 35 is fixedly connected with a mounting seat 31. The mounting seat 31 is cooperatively connected with the output end of the electro-hydraulic push rod 2, and the connection structure is detachable.

[0033] Through this setting, it is convenient to install and disassemble the pressing component 3, facilitating the subsequent replacement or maintenance of the pressing component 3.

[0034] As Figure 2 shown, it further includes a fastening circlip 6, which is cooperatively clamped with the outer side wall of the movable sleeve 35 and is used to cooperate with the top cap 36 to install the test white cloth. An internal thread is provided on the inner side wall of one end of the movable sleeve 35 away from the mounting seat 31, and a threaded rod that is threadedly connected with the internal thread is provided at the end of the top cap 36. Through this setting, it is convenient to replace the spring 7 after disassembling the top cap 36.

[0035] By wrapping the test white cloth around the top cap 36 and ensuring that the test white cloth covering the end area of the top cap 36 is closely attached to the end of the top cap 36 without wrinkles, the subsequent installation is completed by the fastening circlip 6 cooperating with the outer side wall of the movable sleeve 35 to clamp the test white cloth.

[0036] As Figure 3 shown, two oppositely arranged limiting grooves 33 are provided on the outer side wall of the polished rod 32. The limiting grooves 33 are in a linear groove structure. Two oppositely arranged limiting blocks 38 are provided at one end of the inner side wall of the movable sleeve 35 away from the top cap 36, and the two limiting blocks 38 are slidably connected with the two movable sleeves 35.

[0037] Through this setting, rotational limitation is carried out on the sliding connection between the polished rod 32 and the movable sleeve 35, avoiding the top cap 36 connected to the movable sleeve 35 from synchronously rotating with the rotational friction component 5 under the action of friction force during the rotational friction test, resulting in a reduction in the actual friction test stroke and inaccurate color fastness test data.

[0038] As Figure 3 shown, a chute 34 is provided at one end of the polished rod 32 away from the mounting seat 31. A sliding rod 37 is provided at one end of the top cap 36 close to the polished rod 32, and the sliding rod 37 is slidably connected with the chute 34.

[0039] Through this setting, the overall structural stability of the pressing component 3 is improved, that is, the straightness of the movable connection between the top cap 36 and the movable sleeve 35 and the polished rod 32, ensuring the device accuracy and extending the service life of the device.

[0040] As Figure 4 shown, the spring 7 is set to abut against the end wall of the polished rod 32 and the end wall of the top cap 36 at both ends during operation, and the spring 7 is integrally sleeved on the rod body of the sliding rod 37.

[0041] Among them, when the electro-hydraulic push rod 2 is in the initial state, that is, when the push rod is in the retracted state, the round convex platform 54 of the top cap 36 is relatively far away. At this time, both ends of the spring 7 are respectively in contact with the end face of the top cap 36 located inside the movable sleeve 35 and the limit block 38 located inside the movable sleeve 35. During operation, one end of the spring 7 continuously contacts the top cap 36. As the electro-hydraulic push rod 2 pushes the pressure application assembly 3 towards the rotational friction assembly 5 and contacts it, the electro-hydraulic push rod 2 continues to advance. Since the top cap 36 and the movable sleeve 35 are limited, the electro-hydraulic push rod 2 pushes the optical rod 32 into the inside of the movable sleeve 35. When the end face of the optical rod 32 extending into the inside of the movable sleeve 35 exceeds the inner end face of the limit block 38, the optical rod 32 replaces the limit block 38 and contacts the spring 7. As the optical rod 32 continues to be pushed in, the spring 7 is compressed to store energy and applies an equal thrust to the top cap 36 in contact with the convex platform 54.

[0042] As Figure 5 shown, at the center position of one end of the rotating disc 51 away from the search book convex platform 54, there is a rotating shaft 56 for connecting to the output end of the motor 4, and the connection structure is detachable.

[0043] With this setting, it is convenient for installation and disassembly.

[0044] As Figure 5 shown, it also includes a pressure plate 55, which is connected to the convex platform 54. The pressure plate 55 is entirely located inside the inner cavity 53 and cooperates with the end wall on the side of the inner cavity 53 close to the rotating shaft 56 to apply pressure to the pressure sensor 8.

[0045] Among them, both the pressure plate 55 and the convex platform 54 are circular plate structures, and the diameter of the pressure plate 55 is larger than that of the convex platform 54 to prevent the convex platform 54 from detaching from the rotating disc 51.

[0046] As Figure 5 shown, it also includes a magnetic disk 52, which is made of the same magnet material as the rotating disc 51 and is set to magnetically attract each other when installing and testing the fabric. A through hole 57 is opened at the center position of the magnetic disk 52 for cooperating with the convex platform 54 for clamping.

[0047] By attaching the test fabric to the surface of the rotating disc 51 and ensuring that the fabric covering the convex platform 54 area is flat, then magnetically attracting the pressure plate 55 to the surface of the rotating disc 51 and making the entire convex platform 54 expose from the through hole 57, the installation of the test fabric is completed through the magnetic attraction and clamping between the pressure plate 55 and the rotating disc 51.

[0048] In the actual use of the technical solution provided by the present utility model, first, the pressure application component 3 and the rotational friction component 5 are respectively installed on the output ends of the electro-hydraulic push rod 2 and the motor 4; subsequently, the test white cloth is wrapped around the top cap 36, and it is ensured that the test white cloth covering the end area of the top cap 36 is in close contact with the end of the top cap 36 without wrinkles. Subsequently, the fastening snap ring 6 is used to cooperate with the outer side wall of the movable sleeve 35 to clamp the test white cloth to complete the installation. The test cloth is attached to the surface of the rotating disk 51, and it is ensured that the cloth covering the boss 54 area is flat. Subsequently, the pressing plate 55 is magnetically attracted to the surface of the rotating disk 51, and the entire boss 54 is exposed from the through hole 57. Through the magnetic attraction and clamping of the pressing plate 55 and the rotating disk 51, the installation of the test cloth is completed; subsequently, the electro-hydraulic push rod 2 is started. As the electro-hydraulic push rod 2 pushes the pressure application component 3 to approach and contact the rotational friction component 5, the electro-hydraulic push rod 2 continues to advance. Since the top cap 36 and the movable sleeve 35 are limited, the electro-hydraulic push rod 2 pushes the optical rod 32 into the interior of the movable sleeve 35 until the optical rod 32 replaces the limit block 38 and abuts against the spring 7. As the optical rod 32 is further pushed in, the spring 7 is compressed to store energy, and an equal thrust is applied to the top cap 36 abutting against the boss 54, cooperating with the test white cloth and the test cloth squeezed and fitted by the boss 54. At this time, the pressure sensor 8 is squeezed by the pressing plate 55. By comparing the pressure value detected by the pressure sensor 8 with the rated value, the advancement and retraction of the voltage push rod are controlled. When the actually detected pressure value is greater than the rated value, the control module controls the output end of the electro-hydraulic push rod 2 to retract. On the contrary, it controls its extension until the actually detected value by the pressure sensor 8 is equal to the rated value; subsequently, the motor 4 is started to drive the rotational friction component 5 to realize the rotational friction with the test white cloth. After rotating a set number of turns, the motor 4 stops, and the electro-hydraulic push rod 2 resets. Finally, the test white cloth is taken off for chromaticity detection, and the color fastness of the tested cloth is judged according to the dyeing result, and the color fastness detection of the textile is completed.
