Description

Technical Field

[0001] This invention relates to the field of color fastness testing technology, specifically to a fabric color fastness rubbing test device. Background Technology

[0002] Fabric color fastness refers to the degree to which the color printed on the fabric resists external influences. It is an important indicator of fabric quality. During wear and storage, printed and dyed fabrics may fade or change color due to light, sweat, friction, washing, ironing, etc., thus affecting the appearance of the garment. Rubbing color fastness refers to the degree of color loss of dyed fabric after rubbing. It can be divided into dry rubbing and wet rubbing. Fabrics with poor rubbing color fastness will have a limited service life. Therefore, it is necessary to conduct rubbing tests on the color fastness of the fabric before it is made into a finished product.

[0003] Publication No. CN210465234U discloses a friction tester for testing the color fastness of fabrics, including a worktable, a tray fixedly mounted on the worktable for fixing the fabric to be tested, a turntable coaxially arranged with the tray, and a drive assembly for driving the turntable. The drive assembly is housed inside a chassis, and an electrical control box for supplying power to the drive assembly is fixedly mounted at the rear end of the chassis. The electrical control box is integrally formed with the chassis, and the chassis and electrical control box constitute the main body of the worktable. This facilitates the rotation of the turntable by the drive assembly, thereby facilitating the friction of the turntable on the tray and enabling the detection of the coefficient of friction of the fabric's color fastness. This effectively improves the accuracy of this invention. However, this patent still has the following problems in actual use:

[0004] While this fabric color fastness testing rubbing instrument can test the color fastness of different fabrics, the data obtained using only dry rubbing is not representative, as it involves both dry and wet rubbing tests. Furthermore, when testing dark denim, three pre-rubbing processes are required to remove loose dye before color fastness testing, necessitating three changes of the rubbing cloth. This hinders rapid cloth replacement and affects testing efficiency. Additionally, in existing technologies, the direction of cloth switching often overlaps with the direction of reciprocating rubbing, causing the rubbing head to wobble and become unstable, thus affecting the accuracy of the fabric color fastness rubbing test data.

[0005] Therefore, a fabric color fastness rubbing test device is proposed to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide a fabric color fastness rubbing test device to solve the problems mentioned in the background art.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: This fabric color fastness rubbing test device allows for the replacement of the rubbing cloth by switching the connecting rubbing head and the mounting ring, thereby eliminating the floating color of dark denim and performing rubbing tests on dark denim. Utilizing the locking clip's engagement with the connecting bracket, the switching ring is fixed after switching, improving the stability of the connecting rubbing head and the mounting ring. Furthermore, by utilizing the sliding connection between the internal pressing sliding rod and the pressing sliding sleeve of the pressing fixing bracket, the pressing rotating rod drives the laying plate to rotate, and the pressing block presses and fixes the fabric and the rubbing fixing disc, improving the stability of the fabric rubbing test. The specific details are as follows:

[0023] 1. By setting up a friction detection mechanism, the fixed pendulum can be rotated to separate from the locking pin. By pulling out the locking pin, the rotating bearing is pulled outward, causing the rotating sleeve and locking bracket to move. When the locking bracket separates from the diamond-shaped drive shaft of the friction motor, the rotating switching ring drives the connecting bracket to rotate, thus enabling the switching of the connecting friction head and the mounting ring. When testing dark denim, the friction cloth can be replaced by switching the connecting friction head and the mounting ring, thereby eliminating the loose color of the dark denim and facilitating the friction test of the color fastness of the dark denim. Utilizing the locking clip's engagement with the connecting bracket, the switching ring can be fixed after switching, improving the stability of the connecting friction head and the mounting ring. At the same time, utilizing the engagement of the connecting tube and the connecting slot, water from the humidifying tank can be pumped in via a water pump. The friction cloth wrapped around the outside of the connecting friction head is moistened at the rotating sleeve and connecting friction head, enabling both dry and wet friction tests on the fabric, thus improving the accuracy of fabric test data. The friction motor drives the diamond drive shaft and the locking bracket to rotate, which in turn drives the rotating sleeve, connecting friction head, and mounting ring to rotate, allowing for rotational friction on the fabric. By starting the lifting motor, the lifting rotating rod and bevel gear transmission assembly are driven to rotate, which in turn drives the lifting threaded rod to rotate. Simultaneously, the lifting threaded sleeve drives the reciprocating bracket to move up and down, moving the connecting friction head to the top of the fabric. The transverse reciprocating motor is then started to drive the first sprocket transmission assembly and the transverse reciprocating threaded rod to rotate, which in turn drives the transverse reciprocating threaded sleeve to move the detection limit plate and the connecting friction head laterally back and forth, enabling transverse friction testing of the fabric.

[0024] 2. By setting up a fabric fixing mechanism, not only can the longitudinal reciprocating motor drive the second sprocket transmission assembly and the longitudinal reciprocating threaded rod to rotate, causing the longitudinal reciprocating threaded sleeve to drive the lifting bracket and the connecting friction head to move longitudinally back and forth, thus realizing the longitudinal friction detection of the fabric, the fabric to be tested is placed on the friction fixing plate for initial fabric fixing. The pressing motor is started to drive the fourth sprocket transmission assembly and the pressing threaded rod to rotate, causing the pressing threaded sleeve to drive the pressing fixing bracket and the laying plate to move up and down. The laying plate is moved to the middle position of the fabric. The laying motor is started to drive the third sprocket transmission assembly and the laying bidirectional threaded rod to rotate, causing the laying threaded sleeve to drive the pressing bracket to move relative to each other. Utilizing the guiding effect of the guide laying roller, the laying plate is moved relative to each other when the fabric is laid. By the mutual separation of the two laying plates, the fabric is laid flat. Utilizing the sliding connection between the pressing sliding rod and the pressing sliding sleeve inside the pressing fixing bracket, and under the elastic force of the pressing spring, the pressing rotating rod drives the laying plate to rotate. The pressing block is used to press and fix the fabric and the friction fixing plate, improving the stability of the fabric friction detection. Attached Figure Description

The laying board 225 is moved to the middle position of the fabric. Then, the laying motor 210 is started to drive the third sprocket transmission assembly.

The pressing block 228 presses and fixes the fabric and the friction fixing disc 203, improving the stability of the fabric friction detection.

[0042] Before laying the fabric, the fabric is placed on the friction fixing plate 203. Then, the laying plate 225 is moved to the upper middle position of the fabric. The pressing motor 216 drives 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 and the laying plate 225 to move up and down. First, the laying plate 225 is moved to the top of the fabric. The laying plate 225 continues to descend. Under the action of the pressing spring 223, the laying plate 225 can rotate and press the fabric, increasing the friction required for laying. The laying motor 210 drives the third sprocket transmission assembly 211 and the laying bidirectional threaded rod 212 to rotate, so that the laying threaded sleeve 213 drives the pressing bracket 214 and the two laying plates 225 to move from the middle to both sides, thereby achieving the laying of the fabric.

[0043] Working principle: Before using this fabric color fastness rubbing test device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the longitudinal reciprocating motor 205 drives the second sprocket transmission assembly 206 and the longitudinal reciprocating threaded rod 207 to rotate, causing the longitudinal reciprocating threaded sleeve 208 to drive the lifting bracket 131 and the connecting friction head 119 to move longitudinally back and forth, thereby realizing the longitudinal friction detection of the fabric. The fabric to be tested is placed on the friction fixing plate 203 for initial fixing of the fabric. Then, the pressing motor 216 is started to drive the fourth sprocket transmission assembly 217 and the pressing threaded rod 218 to rotate, causing the pressing threaded sleeve 219 to drive the pressing fixing bracket 220. The laying plate 225 is raised and lowered, moving to the middle position of the fabric. The laying motor 210 is started, driving the third sprocket transmission assembly 211 and the laying bidirectional threaded rod 212 to rotate. This causes the laying threaded sleeve 213 to drive the pressing bracket 214 to move relative to each other. Utilizing the guiding action of the guide laying roller 227, the laying plate 225 moves relative to each other during fabric laying. By moving the two laying plates 225 away from each other, the fabric laying operation is achieved. The pressing sliding rod 221 inside the pressing fixing bracket 220 and the pressing... The sliding sleeve 222 features a sliding connection, and under the elastic force of the compression spring 223, the compression rotating rod 224 drives the laying plate 225 to rotate. The compression block 228 is used to compress and fix the fabric and the friction fixing plate 203, improving the stability of the fabric friction detection. Before laying the fabric, the fabric is placed on the friction fixing plate 203, and then the laying plate 225 is moved to a position above the middle of the fabric. The compression motor 216 drives the fourth sprocket transmission assembly 217 and the compression threaded rod 218 to rotate, causing the compression threaded sleeve 222 to rotate. 19 drives the pressing and fixing bracket 220 and the laying plate 225 to move up and down. First, the laying plate 225 is moved to the top of the fabric. Then, the laying plate 225 continues to descend. Under the action of the pressing spring 223, the laying plate 225 can rotate and press the fabric, increasing the friction required for flattening. The flattening motor 210 drives the third sprocket transmission assembly 211 and the flattening bidirectional threaded rod 212 to rotate, so that the flattening threaded sleeve 213 drives the pressing bracket 214 and the two laying plates 225 to move from the middle to both sides, thereby achieving the flattening of the fabric.

[0044] Secondly, rotate the fixed pendulum 111 to separate it from the locking pin 108. By pulling out the locking pin 108, the rotating bearing 114 is pulled outward to move the rotating sleeve 115 and the engaging bracket 118. When the engaging bracket 118 separates from the diamond-shaped drive shaft 125 of the friction motor 124, the rotating switching ring 107 drives the connecting bracket 106 to rotate, thereby enabling the switching of the connecting friction head 119 and the mounting ring 120. When performing 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. Utilizing the engaging connection between the locking clip 110 and the connecting bracket 106, the switched switching ring 107 can be fixed, improving the stability of the connecting friction head 119 and the mounting ring 120.

[0045] Finally, utilizing the engaging connection between the connecting tube 126 and the connecting slot 117, water from the humidifying tank 129 can be pumped by the water pump 127 into the rotating sleeve 115 and the connecting friction head 119, thereby wetting the friction cloth wrapped around the outside of the connecting friction head 119. This allows for both dry and wet friction tests of the fabric, improving the accuracy of the fabric test data. The friction motor 124 drives the diamond-shaped drive shaft 125 and the engaging bracket 118 to rotate, which in turn causes the engaging bracket 118 to drive the rotating sleeve 115, the connecting friction head 119, and the mounting ring 120 to rotate. It can perform rotational friction on the fabric. By starting the lifting motor 133, the lifting rotating rod 134 and the bevel gear transmission assembly 135 are driven to rotate, which in turn drives the lifting threaded rod 136 to rotate. At the same time, the lifting threaded sleeve 137 drives the reciprocating bracket 138 to move up and down, moving the connecting friction head 119 to the top of the fabric. Then, the transverse reciprocating motor 139 is started to drive the first sprocket transmission assembly 140 and the transverse reciprocating threaded rod 141 to rotate, which in turn drives the transverse reciprocating threaded sleeve 142 to move the detection limit plate 101 and the connecting friction head 119 transversely and reciprocally, thus enabling transverse friction detection of the fabric.
