Description

TECHNICAL FIELD

[0001] The utility model relates to cloth testing equipment technical field, concretely is textile static water pressure tester. BACKGROUND

[0002] The fabric static water pressure tester is a tester, which is suitable for fabric static water pressure determination and can also be used to determine the static water pressure performance of other coating materials. The principle of the textile static water pressure tester is to apply continuously increasing (dynamic test) or consistent (static test) water pressure to the sample until water seeps out from three different positions of the sample, and then measure and calculate the average maximum water pressure of the fabric. This value is the water repellency of the sample. For example, the patent with the announcement number CN104390890B discloses a fabric static water pressure tester, and the patent with the announcement number CN211206143U discloses a monitoring type fabric static water pressure tester. Both are testers disclosed in the prior art. However, the amount of water added to the placing block of the existing tester needs to be controlled manually, and it is impossible to ensure that the amount of water added each time is consistent, which may affect the test results. Therefore, how to ensure that the amount of water added each time is consistent is a technical problem to be solved by the present application. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model provides a textile static water pressure tester, which scrapes the water surface in the placing block by a scraping member, so as to ensure that the water level is consistent each time.

[0004] The technical scheme of the utility model is as follows:

[0005] A textile static water pressure tester comprises a rack, a fabric mounting table placed on the rack, a fabric fixing mechanism, and a water adjusting mechanism. The surface of the fabric mounting table is provided with a placing block for placing the fabric. The placing block is provided with a water storage cavity for storing water. The bottom surface of the water storage cavity is connected with the water adjusting mechanism through a pipeline. The axial upper end surface of the placing block is used to abut and fix the fabric with the fabric fixing mechanism. A scraping member is rotatably arranged on the surface of the fabric mounting table. The scraping end of the scraping member and the upper plane of the placing block have the same height. The scraping member sweeps over the upper surface of the placing block by rotating, so as to level the liquid in the placing block.

[0006] In summary, the above technical scheme has the following beneficial effects: the use process of the application is that, after water is added in the placing block through the water adjusting mechanism until the water flows out from the side wall of the placing block, the water on the placing block is scraped flat by rotating the water scraping piece on the upper plane of the placing block, so that the amount of water added in the placing block each time is consistent, and the variables of different test fabrics are kept to a minimum. In addition, if the water is not scraped after the water in the placing block is just full, the water will form a convex surface, so that the test fabric will immediately touch the water as soon as it is placed on, which will also affect the test result to some extent. The application is provided with the water scraping piece, so that the water in the placing block is scraped flat, and the test fabric will not immediately immerse in the water when it is placed on the placing block, so that the test result is more accurate.

[0013] The fabric fixing mechanism 11 and the water regulating mechanism 12 in the application are prior art, and a kind of fabric hydrostatic pressure tester is disclosed in the patent with the publication number CN104390890B, water supply tank is extruded or separated from pipeline by water regulating mechanism 12, so as to supply water or pump water to the water storage cavity of placement block 30, and specific control principle refers to prior art.The fabric fixing mechanism 11 includes linkage, cylinder and fixed piece for pressing fabric, the cylinder drives the fixed piece to move up and down by linkage, so as to cooperate with placement block 30 and press fabric, and specific operating principle and mechanism refer to prior art.The above prior art is not the improvement of the application, so the drawing is not fully represented.

[0014] The use process of the application is, after water is added in placement block 30 by water regulating mechanism 12 until water flows out from the side wall of placement block 30, water scraping part 40 is swept on the upper plane of placement block 30 by rotation, water on placement block 30 can be scraped flat, so that the water amount added in placement block 30 each time is consistent, and the variable of different fabrics to be tested is kept minimum.In addition, if water is not scraped after water in placement block 30 is just full, water will form convex surface, so that the fabric to be tested is immediately immersed in water after being placed on placement block 30, which will also affect test result to some extent, the water in placement block 30 is scraped flat by the setting of water scraping part 40, so that the fabric to be tested is not immediately immersed in water when being placed on placement block 30, so that the test result is more accurate.

[0015] The wiper 40 comprises a fixed rod 41, a rotating ring 42 and a wiper strip 43. The fixed rod 41 is arranged on the fabric mounting table 20. The rotating ring 42 is rotatably arranged on the upper end of the fixed rod 41. The wiper strip 43 is arranged on the outer side wall of the rotating ring 42 and extends in the horizontal direction. The length of the wiper strip 43 is greater than the distance from the fixed rod 41 to the farthest end of the placing block 30. The height of the wiper end 44 below the wiper strip 43 is the same as the height of the upper plane of the placing block 30. The fixed rod 41 is arranged at any position around the placing block 30. Preferably, the fixed rod 41 is arranged on the inner side of the placing block 30 close to the fabric fixing mechanism 11 and within the range of 2-5 cm away from the placing block 30, so as not to affect the contact between the fabric fixing mechanism 11 and the placing block 30. The rotating ring 42 can be rotatably connected to the upper end of the fixed rod 41 through a bearing or can be rotatably connected to the fixed rod 41 by forming a rotating groove on the fixed rod 41. The length of the wiper strip 43 is greater than the distance from the fixed rod 41 to the farthest end of the placing block 30, which can ensure that the rotating range of the wiper strip 43 covers the area where the placing block 30 is located. When the wiper strip 43 is not in use, it can be rotated to the side and does not cover the placing block 30.

[0016] A wiper end 44 made of rubber is arranged below the wiper strip 43. The main body of the wiper strip 43 is made of rigid material, and the lower plane is provided with rubber, silicone or other materials as the wiper end for better scraping of excess water.

[0017] As shown in Figure 3 , the fabric mounting table 20 is provided with a row of drainage grooves 21 around the placing block 30. The drainage grooves 21 are provided with drainage openings 22. The drainage openings 22 are connected to the water storage barrel 24 through the drainage pipe 23 for drainage. The hydrostatic pressure tester needs to continuously add water in the placing block 30 during use. Therefore, there is likely to be accumulated water on the fabric mounting table 20 when the fabric hydrostatic pressure test is performed. The accumulated water can be well collected through the drainage grooves 21 and transported to the water storage barrel for collection through the drainage pipe 23. The rack 10 has a space for installing various mechanisms. The drainage opening 22 communicates with the internal space of the rack 10 through the drainage groove 21 of the fabric mounting table 20, and then the drainage pipe 23 is inserted into the drainage opening 22 to connect the water storage barrel in the rack 10 for drainage.

[0018] The fabric mounting table 20 is linearly formed with an inclined surface from the placing block 30 to the drainage groove 21. The fabric mounting table 20 is inclined downward from the periphery of the placing block 30 until reaching the drainage groove 21. In this way, when the water on the placing block 30 overflows or is scraped off, it can flow along the inclined surface to the drainage groove 21 and further to the water storage barrel.
