Therefore, the detection of fabric dry and wet rubbing color fastness is a very important detection.

The utility model solves the problems that the under-pressure structure of the friction head of the existing dry and wet rubbing color fastness tester is complex and it is not convenient to install sheet-shaped printed printing paste specimen textiles for testing, and achieves the purpose of simple structure and convenient operation.

[0004] This device fixes the fabric through two groups of clamping assemblies. However, since most fabrics have a certain degree of ductility, when the friction head is rubbing, the fabric is prone to deformation, and the surface of the fabric is prone to slide along with the friction head, resulting in an inability to effectively conduct a friction experiment on the fabric and a low accuracy of the detection data.

[0005] Therefore, it is very necessary to invent a dry and wet rubbing color fastness tester to solve the above problems. Content of the Utility Model

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the present utility model will be further introduced in detail below in conjunction with the accompanying drawings.

[0031] The present utility model provides a wet and dry friction color fastness tester as shown in Figures 1 to 3 Figure, which includes an equipment box body 1. A support plate 11 is fixedly connected to the upper side position of the front surface of the equipment box body 1. A friction assembly is arranged at the front end of the support plate 11. The friction assembly includes a first electric cylinder 12 and an equipment shell 13. The first electric cylinder 12 is fixedly installed on the upper surface of the front end of the support plate 11. The equipment shell 13 is fixedly connected to the output end of the first electric cylinder 12. An electric motor is fixedly installed inside the equipment shell 13. The output end of the electric motor is fixedly connected to a friction head. A first connecting rod 210 is fixedly connected to the lower side position of the front surface of the equipment box body 1. The front end of the first connecting rod 210 is fixedly connected to a fixed table 2. A fixing mechanism is arranged on the surface of the fixed table 2. The fixing mechanism includes a first fixing frame 22, a second electric cylinder 24 and a second fixing frame 3.

[0032] Among them, the fabric is fixed by the cooperation of the fixed table 2, the first fixing frame 22 and the second fixing frame 3. At the same time, the second electric cylinder 24 lifts the first fixing frame 22 upward to support the fabric upward, reducing the elasticity of the fabric during the friction process. Then, the telescopic rod of the first electric cylinder 12 pushes the equipment shell 13 downward, so that the friction head tightly abuts against the surface of the fabric. Next, the output end of the electric motor drives the friction head to rotate, and the surface of the fabric is rubbed, effectively realizing the friction test on the fabric and improving the detection accuracy.

[0033] Refer to Figures 2 to 4 , a device groove 21 is formed on the upper surface of the fixed table 2. The first fixing frame 22 is arranged inside the device groove 21. A support rod 23 is fixedly connected to the lower surface of the first fixing frame 22. The second electric cylinder 24 is fixedly installed at the bottom of the fixed table 2. The output end of the second electric cylinder 24 penetrates the bottom wall of the fixed table 2 and is fixedly connected to the middle part of the support rod 23. Support columns 25 are fixedly connected to the front, rear, left and right middle positions of the bottom wall of the fixed table 2. A positioning rod 26 is slidably connected inside the support column 25. The upper end of the positioning rod 26 penetrates the bottom wall of the fixed table 2 and is fixedly connected to the front, rear, left and right ends of the support rod 23. The lower end of the support column 25 is fixedly connected with an anti-slip gasket 27. The lower surface of the second fixing frame 3 abuts against the upper end of the side wall of the fixed table 2. The rear end of the second fixing frame 3 is fixedly connected with a second connecting rod 31. The rear end of the second connecting rod 31 is rotatably connected with the rear end of the first connecting rod 210.

[0034] Specifically, during the feeding process, the second fixing frame 3 is rotated upward, and then the fabric is laid on the upper side of the first fixing frame 22. Then the second fixing frame 3 is rotated downward. The lower surface of the second fixing frame 3 cooperates with the upper end of the side wall of the fixed table 2 to clamp and fix the four sides of the fabric, fixing the fabric. Then, the telescopic rod of the second electric cylinder 24 pushes the first fixing frame 22 upward. At this time, the first fixing frame 22 supports the fabric upward. When the elasticity of the fabric reaches the maximum value, the first fixing frame 22 stops moving. Then, the friction head is used to conduct a friction test on the surface of the fabric. In addition, during the upward movement of the first fixing frame 22, the positioning rod 26 slides upward on the surface of the support column 25, improving the stability of the first fixing frame 22.

[0036] At the same time, after the lower surface of the second fixing frame 3 and the upper end of the side wall of the fixed table 2 cooperate to clamp and fix the four sides of the fabric, the second positioning block 35 is rotated downward, and the second positioning block 35 is clamped on the left and right sides of the clamping block 28. At this time, the second transmission block 37 is clamped under the rubber cushion block 29. Then the pressing plate 38 is rotated downward to drive the second transmission block 37 to rotate, and the long side of the second transmission block 37 is rotated to the upper side to squeeze the rubber cushion block 29, so as to lock and fix the second fixing frame 3, thereby facilitating the quick locking and fixing of the fabric.

[0037] The working principle of the present utility model: The fixed table 2, the first fixing frame 22 and the second fixing frame 3 cooperate to fix the fabric. At the same time, the second electric cylinder 24 lifts the first fixing frame 22 upward to support the fabric upward, reducing the elasticity of the fabric during the friction process, realizing an effective friction test on the fabric and improving the detection accuracy; at the same time, the fabric is laid between the first fixing frame 22 and the second fixing frame 3, the second fixing frame 3 is pressed downward, and the four sides of the fabric are fixed in cooperation with the fixed table 2.
