[0002] Throughout the entire lifecycle of paper, from the manufacturing workshop to the end-use application, the water resistance of paper fibers remains one of the core performance indicators for evaluating paper quality. With the continuous advancement of paper production processes and the expansion of paper applications, the requirements for fiber water resistance are becoming increasingly stringent, whether for conventional paper used for writing and printing or for functional paper used in special fields such as packaging and construction.

[0003] A search revealed patent application CN202122764237.5, which discloses a device for testing the water resistance of paper. The device includes a base, a left upright, and a right upright. The base has a groove, and the left and / or right uprights have vertical through holes and drainage holes communicating with the vertical through holes.

[0024] Please see Figure 1-5 A rapid testing device for the water resistance of paper fibers includes a water collection tank 1. A partition 2 is fixedly installed on the inner wall of the water collection tank 1. The water collection tank 1 is made of transparent tempered glass. This design allows the operator to clearly observe the testing status of the paper inside. Multiple drainage holes 3 are evenly opened at the top center of the partition 2. A water spraying and pressing mechanism 4 is fixedly installed on the rear side of the water collection tank 1. This mechanism has the dual functions of spraying water and pressing the paper, which can effectively prevent the paper from shifting during the testing process.

[0025] A drain pipe 5 is fixedly connected to the bottom left side of the water collection tank 1 to facilitate the discharge of water accumulated in the water collection tank 1. A valve is installed on the drain pipe 5.

[0026] A timer 6 is fixedly installed on the left side of the front of the water collection tank 1, which facilitates accurate recording of the time the paper is exposed to water, providing more accurate data support for scientifically evaluating the water resistance of paper fibers.

[0027] Specifically, the water spraying and pressing mechanism 4 includes a vertical plate 401, a top plate 402, an electric push rod 403, a water spraying pipe 404, a rectangular frame 405, a rectangular rubber sealing ring 406, a spray head 407, a water tank 408, a water pump 409, and a drain hose 410. The vertical plate 401 is fixedly connected to the rear side of the water collection tank 1.

[0028] In practice, the top of the vertical plate 401 is fixedly connected to the top plate 402, and the top of the top plate 402 is fixedly connected to the electric push rod 403.

[0029] Specifically, the telescopic end of the electric push rod 403 passes through the top plate 402 and extends to the outside of the top plate 402 and is fixedly connected to a water spray pipe 404. A rectangular frame 405 is fixedly connected to the bottom of the water spray pipe 404, and the rectangular frame 405 is used to press the paper.

[0030] In practice, a rectangular rubber sealing ring 406 is fixedly connected to the bottom of the rectangular frame 405 to enhance the sealing between the rectangular frame 405 and the paper and prevent water from leaking from the edge of the paper. When the rectangular rubber sealing ring 406 contacts the partition 2, all the drainage holes 3 are located inside the rectangular rubber sealing ring 406.

[0031] Multiple spray nozzles 407 are fixedly installed at the bottom center of the water spray pipe 404 for spraying water onto the paper, and a water tank 408 is fixedly installed on the rear side of the vertical plate 401.

[0032] Specifically, a water inlet pipe is fixedly connected to the top of the water tank 408, a water pump 409 is fixedly connected to the bottom left side of the water tank 408, and a water pump pipe is fixedly installed on the right side of the water pump 409 for pumping water from the water tank 408.

[0033] In practice, the right end of the pumping pipe passes through the water tank 408 and extends into the interior of the water tank 408. The top of the water pump 409 is fixedly connected to the drain hose 410, and the end of the drain hose 410 away from the water pump 409 is fixedly connected to the water spray pipe 404.

[0034] Working principle: In use, first, add an appropriate amount of water to the water tank 408 through the water inlet pipe. Then, place the paper to be tested (choose paper with an area approximately the same as that of the partition 2) on the partition 2, ensuring that the paper completely covers the drain hole 3. Then, start the electric push rod 403, which pushes the water spray pipe 404 downward, causing the rectangular frame 405 to press the paper tightly. The rectangular rubber sealing ring 406 is tightly fitted with the paper to prevent water leakage. Start the water pump 409, which draws water from the water tank 408 through the pump pipe and delivers it to the water spray pipe 404 through the drain hose 410. Finally, the spray head 407 sprays water onto the paper. While the spray head 407 is continuously spraying water onto the paper, the operator can observe the changes in the paper through the water collection tank 1 made of transparent tempered glass. At the same time, the timer 6 starts recording the time. When the predetermined testing time is reached, turn off the water pump 409 and the electric push rod 403, open the valve on the drain pipe 5, and drain the water from the water collection tank 1. The water resistance of paper fibers is evaluated based on the paper's permeability and the testing time.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
