Description

Technical Field

[0001] This utility model relates to the field of water repellency testing technology, and in particular to a device for automatically and quantitatively testing the water repellency of spray. Background Technology

[0002] The water repellency of outdoor clothing fabrics is one of the core indicators for evaluating product quality and reliability, directly affecting the product's lifespan, user experience, and suitability for various scenarios. The spray method, a common method for testing the water repellency of materials, works by spraying a certain amount of water onto the surface of the sample and observing the water stains and penetration to determine the water repellency level. Automatic quantitative spray water repellency testing equipment can automatically measure parameters related to water repellency during use, eliminating the need for manual estimation or measurement.

[0003] To meet the requirements of standard compliance testing, testing equipment is generally in a highly locked static spray state during use, which cannot allow different areas of the sample to be evenly subjected to spray pressure and cannot accurately reflect the water repellency effect in actual use. In view of the above reasons, this application proposes a testing device for spray water repellency performance that can automatically quantify. Utility Model Content

A pull handle 613 is fixedly provided on the top of the pull rod 612. A vertical plate 614 is fixedly provided on the top of the horizontal plate 605. A locking screw 615 is movably provided on the vertical plate 614. An internal thread hole is provided on one side of the pull rod 612. The locking screw 615 is compatible with the internal thread hole. A liquid storage tank 606 and a metering pump 607 are respectively provided on the front and back of the horizontal plate 605. A drain pipe is provided at the drain end of the metering pump 607. A spray head 619 is provided at the end of the drain pipe away from the metering pump 607.

A connecting frame is fixedly mounted on the front of the horizontal plate 605, and a second locking screw 617 is movably mounted on the connecting frame. The second locking screw 617 is adapted to the insertion holes. When it is necessary to limit the spray height, the pull rod 612 is pulled to one side, and the pull rod 612 drives one side of the insertion plate 611. Squeeze the spring 610 and disengage it from the slot 608. Then, turn the locking screw 615 clockwise to insert it into the internal threaded hole on one side of the pull rod 612 to position the insert plate 611. Then, turn the locking screw 617 counterclockwise to disengage one end from the insertion hole on the surface of the guide rod 616, supporting the bottom of the horizontal plate 605 and moving it up and down to adjust the spray height. After adjustment, turn the locking screw 617 clockwise to insert it into the insertion hole to fix it. Reference Figure 5 As shown, a swing assembly 7 is provided below the horizontal plate 605. The swing assembly 7 can reduce the spray dead angle. The swing assembly 7 includes a swing rod 701, which is movably connected to the horizontal plate 605. A connecting shaft 702 is fixedly provided at the top of the swing rod 701. The top of the connecting shaft 702 is rotatably connected to the bottom of the horizontal plate 605. A connector 703 is fixedly provided at the top of the swing rod 701, which is fixedly connected to the spray head 619. A drive motor 704 is fixedly provided below the swing rod 701. The output end of the second drive motor 704 is equipped with an eccentric wheel 705. A positioning shaft is fixedly installed at the eccentric part of the eccentric wheel 705. The positioning shaft and the rocker arm 701 are movably connected. The rocker arm 701 is equipped with a limiting groove, which is movably sleeved on the positioning shaft. During spraying, the second drive motor 704 is started, which drives the eccentric wheel 705. The eccentric wheel 705 then drives the rocker arm 701 to swing left and right. The rocker arm 701 then drives the spray head 619 to swing and spray, which can reduce the spray dead angle and improve the accuracy of test data.

[0022] In this embodiment, measuring vessel 4 is used to collect water that slips off the fabric surface, and measuring vessel 5 is used to collect water that permeates the fabric. The total spray volume reflects the water-repellent performance. For standard compliance testing, the horizontal plate 605 can be separated from the connecting plate 604. The spray height of the spray head 619 can be adjusted by pulling the pull rod 612 to one side. The pull rod 612 causes one side of the insert plate 611 to compress the spring 610 and disengage from the slot 608. Then, the locking screw 615 is rotated clockwise to insert into the internal threaded hole on one side of the pull rod 612, thus positioning the insert plate 611. Next, the locking screw 617 is rotated counterclockwise to disengage one end from the insertion hole on the guide rod 616, supporting the bottom of the horizontal plate 605 and allowing it to move up and down, thus adjusting the spray height. After adjustment, the locking screw 617 is rotated clockwise to insert into the insertion hole for fixation. If a mold is needed... To simulate a real-world scenario, the horizontal plate 605 and connecting plate 604 are reconnected, and the locking screw 617 is disengaged from the insertion hole. Then, the drive motor 602 is activated, driving the reciprocating screw 603, which in turn drives the connecting plate 604. The connecting plate 604 then drives the horizontal plate 605, which in turn moves the spray head 619 on one side up and down. This allows different areas of the sample to be evenly subjected to spray pressure, more accurately reflecting the water-repellent effect in actual use. The combination of height-limited spraying and mobile spraying meets both standard compliance testing requirements and can handle simulated testing in real-world scenarios, improving the equipment's versatility. During spraying, the drive motor 704 is activated. The use of the drive motor 704, along with the eccentric wheel 705 and the rocker arm 701, allows the spray head 619 to be in a rocking spraying state, reducing spray dead zones and improving the accuracy of test data.

[0023] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
