Description

Technical Field

[0001] The invention relates to the field of textiles, and in particular to a color fastness detection device for dyed fabrics. Background Art

[0002] Color fastness refers to the resistance of the color of textiles to various effects during processing and use. The fastness grade is assessed based on the discoloration of the sample and the staining of the undyed adjacent fabric. The color fastness test of textiles is a routine test item in the intrinsic quality test of textiles. The rubbing color fastness is to rub the sample to be tested with a standard rubbing white cloth for a certain number of times under a certain pressure, and then use a gray card to grade the color stained on the standard rubbing white cloth. The resulting grade is the measured rubbing color fastness.

[0003] The applicant has found that: generally, when testing color fastness to rubbing, a rubbing fastness meter is usually used for testing. During testing, the rubbing fastness meter can only test one sample at a time, and the testing efficiency is low. Summary of the invention

The lifting part is connected to the support column. When one of the support columns moves to the top of the rotating shaft, the lifting part drives the support column to move upward and generates pressure between the dyed fabric on the support column and the standard friction white cloth of the rotating shaft.

[0011] Furthermore, the lifting part comprises:

[0012] An inner hole located in the cylinder, the opening of the inner hole is located at the end face of the end shaft of the cylinder, and the end shaft is rotatably connected to the second column;

[0014] An arc-shaped groove is provided on the side surface of the central axis and a connecting rod with one end slidably connected to the arc-shaped groove, and the other end of the connecting rod passes through a through hole provided at the bottom of the inner groove and is connected to the support column;

[0015] A lifting assembly is arranged in the central shaft, and is located directly below the rotating shaft, and is used to drive the support column to move upward when one of the support columns rotates to the position directly below the rotating shaft.

[0016] Furthermore, the lifting assembly comprises:

[0017] A connecting groove is provided on the side surface of the central shaft, and the connecting groove is located directly below the rotating shaft;

[0018] A driving rod located at the bottom of the connecting groove and a connecting end provided on the bottom surface of the driving rod, wherein the connecting end is slidably connected to a second sliding groove provided at the bottom of the connecting groove, and one end of the driving rod passes through the end surface of the central axis close to the second column;

Before the detection, the dyed fabrics to be detected are fixed on different support posts so that the dyed fabrics to be detected on each support post are staggered. After the detection is completed, the standard friction white cloth is sleeved on the rotating shaft and fixed. When one of the support posts moves to the top of the rotating shaft, the lifting part drives the support post to move upward, and generates pressure between the dyed fabric on the support post and the standard friction white cloth on the rotating shaft. After the detection is completed, the first motor is started to drive the cylinder to rotate. When one of the support posts moves to the top of the rotating shaft, the first motor stops driving, and the lifting part drives the support post to move upward, and generates pressure between the dyed fabric on the support post and the standard friction white cloth on the rotating shaft. At this time, the second motor is started to drive the rotating shaft to rotate. After rotating for a period of time, the second motor stops driving, and the lifting part restores the support post to its original position. Then the first motor is driven again to rotate the cylinder again. After the next support post moves to the bottom of the rotating shaft, the above steps are repeated. Through this device, multiple samples can be detected at one time, thereby improving the detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Based on the above purpose, the first aspect of the present invention provides an embodiment of a color fastness detection device for dyed fabrics, such as Figure 1 , Figure 2 and Figure 4 As shown, including:

[0035] A base 1 and a first vertical plate 12 and a second vertical plate 13 symmetrically arranged on the upper surface of the base 1;

[0036] A cylinder 2 is located between the first vertical plate 12 and the second vertical plate 13, wherein the end shaft of one end of the cylinder 2 is rotatably connected to the first vertical plate 12, and the end shaft of the other end is rotatably connected to the second vertical plate 13, and the side surface of the cylinder 2 is provided with a plurality of inner grooves 3 parallel to each other;

[0037] A first motor 14 is fixed to the outer side of the first vertical plate 12 through a first fixing member, and the output shaft of the first motor 14 is fixedly connected to the end shaft of one end of the cylinder 2;

[0038] A fixing frame 11 fixed to the base 1, a second motor 25 fixed to the top of the fixing frame 11, and a rotating shaft 10 with one end fixedly connected to the output shaft of the second motor 25, wherein the central axis of the rotating shaft 10 is parallel to the central line of the inner groove 3, and during the inspection, a standard friction white cloth is sleeved on the rotating shaft 10 and fixed;

[0039] The support column 6 is located in the inner groove 3 and the lifting part is located in the cylinder 2. The upper end surface of the support column 6 is used to fix the dyed fabric to be tested. The lifting part is connected to the support column 6. When one of the support columns 6 moves to the top of the rotating shaft 10, the lifting part drives the support column 6 to move upward and generates pressure between the dyed fabric on the support column 6 and the standard friction white cloth of the rotating shaft 10.

[0040] In this embodiment, before the test, the dyed fabric to be tested is fixed to different support posts 6, so that the dyed fabric to be tested on each support post 6 is staggered. After the test is completed, the standard friction white cloth is sleeved on the rotating shaft 10 and fixed. Here, it can be fixed by screws or the like. When one of the support posts 6 moves to the top of the rotating shaft 10, the lifting part drives the support post 6 to move upward, and generates pressure between the dyed fabric on the support post 6 and the standard friction white cloth on the rotating shaft 10. After the test is completed, the first motor 14 is started to drive the cylinder 2 to rotate. When one of the support posts 6 moves to the top of the rotating shaft 10, the lifting part drives the support post 6 to move upward, and generates pressure between the dyed fabric on the support post 6 and the standard friction white cloth on the rotating shaft 10. When the cylinder 2 is directly above the support column 6, the first motor 14 stops driving, and the lifting part drives the support column 6 to move upward, and generates pressure between the dyed fabric on the support column 6 and the standard friction white cloth of the rotating shaft 10. At this time, the second motor 25 starts to drive the rotating shaft 10 to rotate. After rotating for a period of time, the second motor 25 stops driving, and the lifting part restores the support column 6 to its original position. Then the first motor 14 is driven again to make the cylinder 2 rotate again. After the next support column 6 moves to the bottom of the rotating shaft 10, the above steps are repeated. Through this device, multiple samples can be tested at one time, thereby improving the detection efficiency.

[0046] In this embodiment, when the cylinder 2 rotates, the bottom end of the connecting rod 16 rotates in the arc groove 17. When one of the support posts 6 rotates to the bottom of the rotating shaft 10, the lifting assembly moves the support post 6 upward, and finally makes the dyed fabric to be tested on the support post 6 contact with the standard friction white cloth on the rotating shaft 10, and generates appropriate pressure. When the detection of the support post 6 is completed, the lifting assembly restores the support post 6 to its original position.
