Technical Field

[0001] This utility model relates to the technical field of textile auxiliary agent testing devices, and more specifically to a textile auxiliary agent color fastness testing device. Background Technology

[0002] To improve the functionality and coloring effect of textiles, appropriate textile auxiliaries are often added during the processing to give textiles special functions such as softness, water resistance, and wrinkle resistance, thereby improving the overall process of textiles and reducing costs.

[0003] However, after textile production is completed, a series of testing steps are required to ensure that the quality of textiles meets the qualified standards. Among them, color fastness is an important evaluation method for measuring the durability of textiles. In the existing test, multiple pieces of textile fabric of the same area are often cut, fixed, and rubbed by hand with a friction block. Since multiple tests are conducted, if the friction pressure is not evenly distributed, the test values ​​will have certain differences, which will affect the accuracy of the test.

[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-5 As shown, a textile auxiliary color fastness testing device includes:

[0031] Support frame 1, clamping blocks 2 are arranged in a linear array on support frame 1, clamping blocks 2 are provided with detection and contact surface 21, and clamping elements 22 are provided on clamping blocks 2;

[0032] Transmission unit 4 is mounted on support frame 1 and includes screw 43;

[0033] Friction unit 3 is mounted on support frame 1. Friction unit 3 includes guide seat 33, slide 38 and adjusting wheel 36 rotatably mounted on slide 38. A transmission rod 37 is threadedly connected to the shaft of adjusting wheel 36. A pressure sensor 35 is mounted at the end of transmission rod 37.

[0034] A friction wheel 32 is rotatably mounted on the guide seat 33 and faces the detection contact surface 21. The output end of the pressure sensor 35 is engaged with the guide seat 33.

[0035] Specifically, multiple samples of the same area are cut, with the sample area being larger than the area of ​​the testing mating surface 21. The number of samples is consistent with the number of clamping blocks 2. The samples are then placed on the testing mating surface 21. The rotating seat 224 is rotated to allow the clamping wheel 221 to flatten the sample and roll it into the arc groove 23. Under the pull of the first spring 223, the clamping wheel 221 is driven to engage in the arc groove 23, so that the sample is laid flat and fixed on the clamping block 2. Then, a standard white cloth is fixed to the friction wheel 32 by the clamping block 323. The adjusting wheel 36 is then rotated to make the transmission rod 37 slide downward in the vertical direction until the white cloth and the sample come into contact and generate a certain pressure. The magnitude of the pressure is fed back by the pressure sensor 35. This allows for testing under the same pressure and different sample conditions or under different pressure and the same sample conditions, thereby improving the adaptability of the testing device. Compared with the friction method of transmission, this testing method improves the testing accuracy. The pressure sensor 35 can be of model MPX4250D.

[0036] As a further embodiment of this utility model, a groove 321 is provided on the friction wheel 32, and a locking block 323 is locked in the groove 321. One end of the locking block 323 is provided with an arc-shaped surface. A strip of standard white cloth is cut, and the width of the strip of white cloth is consistent with the width of the groove 321 and the length is consistent with the circumference of the friction wheel 32. Then, the white cloth is wrapped into the groove 321 and fixed to the friction wheel 32 by the locking block 323, so as to facilitate the subsequent color fastness test.

[0037] As a further embodiment of this utility model, a second spring 34 is provided on the guide seat 33 and connected to the output end of the pressure sensor 35. The elastic force of the second spring 34 provides a certain buffering effect. When the friction wheel 32 comes into contact with the sample, as the contact force increases, the pressure sensor 35 overcomes the elastic force of the second spring 34, so that the output end contacts the guide seat 33 and detects the pressure applied to the sample.

[0038] As a further embodiment of this utility model, the support frame 1 includes a base plate 15, side plates 13 and a top plate 11. The top plate 11 is mounted on the base plate 15 via two sets of side plates 13. The clamping block 2 is fixed on the base plate 15. The transmission unit 4 is mounted on the side plates 13. The top plate 11 is provided with a slide rail 12. The slide 38 is provided with a guide block 31 that meshes with the slide rail 12. The slide rail 12 is used to improve the sliding stability of the friction unit 3. The slide 38 is provided with a reinforcing rib 381 to improve the robustness of the slide 38.

[0039] As a further embodiment of this utility model, the clamping member 22 includes a rotating seat 224 and a swing block 222 slidably disposed on the rotating seat 224. A clamping wheel 221 is rotatably disposed on the swing block 222. A first spring 223 is disposed between the swing block 222 and the rotating seat 224. The rotating seat 224 is rotatably disposed on the clamping block 2. When the sample is attached to the clamping block 2, the hand rotates the clamping wheel 221 to make the clamping wheel 221 smooth the sample rotation. At this time, the first spring 223 is in a stretched state. After rotating to a certain distance, the clamping wheel 221 will be pulled back by the first spring 223 and inserted into the arc groove 23, thus fixing the sample to the clamping block 2.

[0040] As a further embodiment provided in this utility model, the clamping block 2 is provided with an arc-shaped groove 23 that abuts against the clamping wheel 221. The arc-shaped groove 23 engages with the arc-shaped surface on the clamping wheel 221, thereby improving the clamping effect of the sample.

[0041] As a further embodiment of this utility model, a shim block 14 is provided on the support frame 1 to increase the height of the support frame 1, making it easier to move the device manually. The shim block 14 is a rubber block to improve the stability of the device during operation.

[0042] As a further embodiment of this utility model, the transmission unit 4 includes a first bevel gear 41, a motor 45, and a second bevel gear 44 disposed at the output end of the motor 45. The first bevel gear 41 meshes with the second bevel gear 44, and the first bevel gear 41 engages with the screw 43. The model of the motor 45 is MHMF042L1U4-1116. The motor 45 is used as a power source to control the rotation of the second bevel gear 44 on the output shaft. Since the second bevel gear 44 meshes with the first bevel gear 41, the first bevel gear 41 and the screw 43 rotate synchronously, thereby controlling the friction unit 3 to reciprocate on the support frame 1.

[0043] As a further embodiment provided by this utility model, the number of teeth of the first bevel gear 41 is greater than the number of teeth of the second bevel gear 44, thereby performing deceleration motion and achieving a torque multiplication effect.

[0044] As a further embodiment of this utility model, the support frame 1 is provided with a protective cover 42 that cooperates with the transmission unit 4. The protective cover 42 covers the first bevel gear 41 and the second bevel gear 44 to protect the parts on the transmission unit 4 and reduce dust adhesion to the first bevel gear 41 and the second bevel gear 44.

[0045] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0046] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
