Description

Technical Field

[0001] This utility model relates to the field of textile testing technology, specifically to an automatic wiping device for testing the stain-resistant properties of textiles. Background Technology

[0002] The wiping method is a test method used to evaluate the stain-repellency of textiles. Standard FZ / T 01118-2012, "Test and Evaluation of Stain Repellency of Textiles," Clause 7.2.5 states, "Use a cotton standard lining to vigorously rub the stained area in the same direction. After each wiping, the cotton standard lining should be moved to a clean area and rubbed again, for a total of 30 wipings." This is the most crucial step in the test. Currently, when laboratories conduct stain-repellency tests on textiles according to this description, two people are required: one to hold down the sample and the other to wipe. The wiping person must manually control the direction and number of wiping strokes, which presents the following technical defects:

[0003] 1. Uneven wiping pressure affects the consistency of test results;

[0004] 2. Manual counting is prone to operational errors;

[0005] 3. It is difficult to maintain an absolutely consistent wiping direction;

[0006] 4. Manually controlling the cotton liner to change position is cumbersome, prone to contamination, and cannot guarantee consistent contact area for each wipe. Utility Model Content

Detailed Implementation

[0025] See Figure 1-3 This utility model relates to an automatic wiping device for testing the stain-removing performance of textiles, including a mounting base 1, a rotatable rotating disk clamp 2, and a push rod 3 that can move left and right and up and down. The rotating disk clamp 2 is rotatably mounted on the mounting base 1 via a hollow rotating platform 4, which is driven to rotate by a drive motor and is fixed inside the mounting base 1. The push rod 3 is driven to move by a drive mechanism, which is located on the left side of the rotating disk clamp 2.

[0026] The rotating disk clamp 2 is used to clamp the cotton standard liner 5. The rotating disk clamp 2 includes a rotating disk 2.1 and a pressure cap 2.2. The rotating disk 2.1 is connected to the moving end of the hollow rotating platform 4. The rotating disk 2.1 has multiple positioning bosses 2.1.1 distributed around its circumference. The cotton standard liner 5 is placed on the positioning bosses 2.1.1 and fixed by the pressure cap 2.2. The pressure cap 2.2 has pressure holes corresponding to the positioning bosses 2.1.1. The surface of the positioning bosses 2.1.1 is provided with vacuum adsorption holes 2. 1.2, The rotating disk 2.1 has a built-in hollow cavity 2.1.3. The vacuum adsorption holes 2.1.2 on each positioning boss 2.1.1 are connected to the hollow cavity 2.1.3. The bottom of the hollow cavity 2.1.3 is provided with a vacuum extraction port, which is connected to the vacuum pump 6. When the cotton standard liner 5 is laid on the positioning boss 2.1.1, the vacuum pump 6 is started. The vacuum adsorption holes 2.1.2 adsorb the cotton standard liner 5, which makes it easy to cover the pressure cap 2.2 and ensures that the cotton standard liner 5 is flat after clamping.

[0027] The drive mechanism includes a horizontal lead screw motor 7, a vertical lead screw motor 8, a slide block 9, and a push rod fixing frame 10. The horizontal lead screw motor 7 is placed inside the mounting base, and the horizontal lead screw of the horizontal lead screw motor 7 is connected to the slide block 9. The vertical lead screw motor 8 is fixedly mounted on the slide block 9 extending out of the mounting base 1. The vertical lead screw of the vertical lead screw motor 8 is connected to the push rod fixing frame 10. The push rod fixing frame 10 is connected to the right side of the push rod 3. The push rod 3 is used to clamp the contaminated sample 11. The contaminated sample 11 is set at the bottom of the push rod 3 and fixed by a collar 12.

[0028] The push rod 3 and the rotating disk clamp 2 are set on the central axis of the mounting base 1. The push rod 3 wipes the cotton standard pads close to the push rod 3 on the central axis of the mounting base 1. This position is the wiping station. The rotating disk clamp 2 rotates each cotton standard pad 5 clockwise to the wiping station through the hollow rotating platform 4. The push rod 3 drives the soiled sample 11 on it to wipe the cotton standard pads 5 located at the wiping station. There are 30 positioning bosses 2.1.1 on the rotating disk 2.1 for clamping 30 cotton standard pads 5 at the same time. The positioning bosses 2.1.1 are numbered sequentially from 1 to 30. In the initial state, the positioning boss 2.1.1 numbered 1 is located at the wiping station.

[0029] To prevent the cover 2.2 from shaking during the rotation of the rotating disk clamp 2, multiple magnetic seats 13 are provided around the cover 2.2. During the wiping test, the cover 2.2 and the rotating disk 2.1 are clamped by the magnetic seats 13. After the test, the magnetic seats 13 are released. The magnetic seats 13 are located inside the positioning boss 2.1.1 to avoid the directional movement of the push rod 3.

[0030] The thickness of the positioning boss 2.1.1 is greater than that of the pressure hole, so that the positioning boss 2.1.1 after the cotton standard liner 5 is clamped is higher than the top surface of the pressure cap 2.2, which makes it easier for the soiled sample 11 to contact the cotton standard liner 5 at the wiping station.

[0031] The mounting base 1 is also equipped with a control host 14, which is electrically connected to the drive motors of the horizontal lead screw motor 7, the vertical lead screw motor 8 and the hollow rotary platform 4 respectively.

[0032] Operating instructions:

[0033] Step 1: Place the cotton standard patch 5 on the positioning boss 2.1.1 corresponding to the rotating disk 2.1. The vacuum adsorption hole 2.1.2 adsorbs the cotton standard patch 5. The pressure cap 2.2 is placed on the rotating disk 2.1 to fix 30 cotton standard patches 5. In the initial state, the cotton standard patch 5 on the positioning boss 2.1.1 numbered 1 is located at the wiping station.

[0034] Step 2: The vertical lead screw motor 8 drives the push rod 3 to descend to the designated height on the left side of the wiping station. The horizontal lead screw motor 7 drives the push rod 3 and the soiled sample 11 on it to wipe the cotton standard patch 5 located at the wiping position from left to right. After wiping, the push rod 3 is located on the right side of the wiping position. The push rod 3 is reset (the vertical lead screw motor 8 drives the push rod 3 to rise to the initial height, and then the horizontal lead screw motor 7 drives the push rod 3 to move to the left side of the wiping position). At the same time, the drive motor drives the hollow rotating platform 4 to rotate 12° in one go, and the next piece of cotton standard patch 5 rotates to the wiping station.

[0035] Step 3: Repeat step 2 until all 30 standard cotton pads 5 have been directionally wiped with the soiled sample 11. Then push rod 3 is reset, and the wiping test is over.

[0036] Step 4: Remove the stained sample 11 and evaluate the color difference.

[0037] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
