Description

Technical Field

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

[0002] Fabric color fastness refers to the degree to which the color printed on the fabric can withstand external influences. It is an important indicator of fabric quality. Printed and dyed fabrics will fade or change color during wearing and storage due to light, sweat, friction, washing, ironing, etc., thus affecting the appearance of the clothing. Friction color fastness refers to the degree of color loss of dyed fabrics after friction, which can be divided into dry friction and wet friction. Fabrics with poor friction color fastness will have a limited service life. Therefore, the fabric color fastness needs to be tested for friction before the fabric is made into a finished product.

[0003] Publication No. CN210465234U discloses a friction meter for testing the color fastness of fabrics, comprising a work surface, a support plate fixedly arranged on the work surface for fixing the fabric to be tested, a turntable coaxially arranged with the support plate, and a drive assembly for driving the turntable, wherein the drive assembly is arranged in a chassis, and an electric control box for powering the drive assembly is fixedly arranged at the rear end of the chassis. The electric control box is integrally formed with the chassis, and the chassis and the electric control box constitute a working box body, thereby facilitating the turntable to rotate through the drive assembly, thereby facilitating the turntable to rub the fabric on the support plate, and then facilitating the detection of the friction coefficient of the fabric color fastness through the turntable, thereby effectively improving the use accuracy of the utility model. However, the following problems still exist in the actual use of this patent: Although the friction meter for fabric color fastness testing can test the color fastness of different fabrics, the color fastness test of fabrics includes dry friction test and wet friction test. The test data is not representative only because of the dry friction method. At the same time, when testing dark denim, three pre-rubbings are required to eliminate floating colors before the color fastness test is performed. Therefore, the friction cloth needs to be replaced three times during this process, and the friction cloth cannot be quickly replaced, thereby affecting the efficiency of color fastness testing. In the prior art, when switching the friction cloth, the switching direction and the reciprocating friction direction are prone to overlap, resulting in the shaking and instability of the friction head, affecting the accuracy of the fabric color fastness friction test data.

[0004] Therefore, a fabric color fastness friction detection device is proposed to solve the above problems. Summary of the Invention

The third sprocket transmission assembly 211 and the flattening bidirectional threaded rod 212 are driven to rotate by the flattening motor 210, so that the flattening threaded sleeve 213 drives the pressing bracket 214 and the two paving plates 225 to move from the middle to both sides, thereby flattening the fabric.

[0024] Working principle: Before using this kind of fabric color fastness friction test device, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 11As shown, first, the longitudinal reciprocating motor 205 is used to drive the second sprocket transmission assembly 206 and the longitudinal reciprocating threaded rod 207 to rotate, so that the longitudinal reciprocating threaded sleeve 208 drives the lifting bracket 131 and the connecting friction head 119 to move back and forth longitudinally, thereby realizing the longitudinal friction detection of the fabric. The fabric to be detected is placed on the friction fixing plate 203 for preliminary fixing of the fabric. The pressing motor 216 is started to drive the fourth sprocket transmission assembly 217 and the pressing threaded rod 218 to rotate, so that the pressing threaded sleeve 219 drives the pressing fixing bracket 220 The paving plate 225 is lifted and lowered, and the paving plate 225 is moved to the middle position of the fabric. The paving motor 210 is started to drive the third sprocket transmission component 211 and the paving bidirectional threaded rod 212 to rotate, so that the paving threaded sleeve 213 drives the pressing bracket 214 to move relatively. The guiding effect of the guide paving roller 227 is utilized to drive the paving plate 225 to move relatively when the fabric is being paved. The two paving plates 225 are moved away from each other, thereby realizing the paving operation of the fabric. The sliding rod 221 inside the pressing fixed bracket 220 is pressed and pressed. The sliding sleeve 222 is connected with the sliding connection, and under the elastic force of the pressing spring 223, the pressing rotating rod 224 drives the paving plate 225 to rotate, and the pressing block 228 is used to press and fix the fabric and the friction fixed disk 203 to improve the stability of the fabric friction detection. Before paving the fabric, the fabric is placed on the friction fixed disk 203, and then the paving plate 225 is moved to the upper middle position of the fabric, and the fourth sprocket transmission assembly 217 and the pressing threaded rod 218 are driven to rotate by the pressing motor 216, so that the pressing thread sleeve 2 19 drives the clamping fixing bracket 220 and the paving plate 225 to move up and down, first moves the paving plate 225 to the top of the fabric, and continues to lower the paving plate 225. Under the action of the clamping spring 223, the paving plate 225 can be rotated, and the fabric is pressed to increase the friction required for paving. The third sprocket transmission assembly 211 and the paving bidirectional threaded rod 212 are driven to rotate by the paving motor 210, so that the paving threaded sleeve 213 drives the clamping bracket 214 and the two paving plates 225 to move from the middle to both sides, thereby realizing the flattening of the fabric.

[0025] Secondly, rotate the fixed pendulum 111 to separate the fixed pendulum 111 from the locking pin 108, pull out the locking pin 108, and then pull the rotating bearing 114 outward so that the rotating bearing 114 drives the rotating sleeve 115 and the engaging bracket 118 to move. When the engaging bracket 118 is separated from the diamond drive shaft 125 of the friction motor 124, the rotating switching ring 107 drives the connecting bracket 106 to rotate, so that the connecting friction head 119 and the mounting ring 120 can be switched. When conducting dark denim testing, the friction cloth can be replaced by switching the connecting friction head 119 and the mounting ring 120, thereby eliminating the floating color of the dark denim and facilitating the color fastness friction test of the dark denim. By utilizing the characteristics of the engaging connection between the locking card 110 and the connecting bracket 106, the switched switching ring 107 can be fixed to improve the stability of the connecting friction head 119 and the mounting ring 120.

[0026] Finally, by utilizing the characteristics of the connection between the connecting tube 126 and the connecting slot 117, the water in the moistening water tank 129 can be pumped into the rotating sleeve 115 and the connecting friction head 119 through the water pump 127, thereby wetting the friction cloth wrapped on the outside of the connecting friction head 119. Not only can the dry friction test of the fabric be performed, but the wet friction test of the fabric can also be performed, thereby improving the accuracy of the fabric detection data. The friction motor 124 drives the diamond drive shaft 125 and the engaging bracket 118 to rotate, so that the engaging bracket 118 drives the rotating sleeve 115, the connecting friction head 119 and the mounting ring 120 to rotate. The fabric can be subjected to rotational friction. By starting the lifting motor 133 to drive the lifting rotating rod 134 and the bevel gear transmission assembly 135 to rotate, the bevel gear transmission assembly 135 drives the lifting threaded rod 136 to rotate, and at the same time the lifting threaded sleeve 137 drives the reciprocating bracket 138 to move up and down, and moves the connecting friction head 119 to the top of the fabric. The horizontal reciprocating motor 139 is started to drive the first sprocket transmission assembly 140 and the horizontal reciprocating threaded rod 141 to rotate, so that the horizontal reciprocating threaded sleeve 142 drives the detection limit plate 101 and the connecting friction head 119 to move back and forth horizontally, so that the horizontal friction detection of the fabric can be performed.
