Description

Technical Field

[0001] This utility model relates to the field of water resistance testing technology, specifically to a device for testing the water resistance of sized paper. Background Technology

[0002] Sizing is a crucial process in paper production, aiming to improve the paper's water resistance and printability. The water resistance of sized paper directly impacts product quality and application scenarios. Currently, the industry primarily uses a single-sample testing mode for testing the water resistance of sized paper. This means that only one paper sample can be fixed for spraying or immersion testing at a time. After testing, the sample must be disassembled, the device cleaned, and the next sample tested. Single-sample testing leads to frequent interruptions in the testing process, making continuous operation impossible. For the needs of multi-batch, multi-sample testing in mass production scenarios, the efficiency is extremely low. Repeated sample loading and unloading easily introduces human error, and it is difficult to maintain completely consistent testing conditions (such as spray pressure, water volume, and time), affecting the accuracy and comparability of test results.

[0004] Therefore, the purpose of this invention is to provide a device for testing the water resistance of sized paper, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for testing the water resistance of sized paper includes a base plate and a vertical rod. The vertical rod is fixedly mounted on the upper surface of the base plate. A turntable is movably sleeved on the wall of the vertical rod. The surface of the turntable has multiple water inlets, and the bottom of each water inlet has a water outlet. A placement groove is formed between the water inlets and the water outlets. A sealing mechanism for sealing the sidewall of the placement groove is provided on the outer side of the turntable.

[0023] This utility model discloses a device for testing the water resistance of sized paper.

[0024] Reference Figure 1-3 A device for testing the water resistance of sized paper includes a base plate 1 and a vertical rod 2. The vertical rod 2 is fixedly mounted on the upper surface of the base plate 1. A turntable 4 is movably sleeved on the wall of the vertical rod 2. The surface of the turntable 4 has multiple water inlets, and the bottom of each water inlet has a water outlet. A placement groove is provided between the water inlets and the water outlets. A sealing mechanism for sealing the sidewall of the placement groove is provided on the outside of the turntable 4. A top plate 11 is fixedly mounted on the top of the vertical rod 2. A water tank 12 is fixedly mounted on the upper surface of the top plate 11. A water inlet head 13 is provided at the bottom of the water tank 12. A sliding sleeve 3 is movably sleeved on the lower end of the vertical rod 2. The upper side of the sliding sleeve 3 is rotatably connected to the turntable 4. A support plate 6 is fixedly mounted on the lower side of the sliding sleeve 3. A first transmission mechanism for driving the turntable 4 to rotate is provided on the upper surface of the support plate 6. A second transmission mechanism for driving the turntable 4 to move longitudinally is provided on one side of the upper surface of the base plate 1.

[0025] Reference Figure 1-3 The sealing mechanism includes a sealing ring 10 and a threaded rod 15. The sealing ring 10 is slidably sleeved on the outside of the turntable 4. A first side plate 14 is fixedly installed on one side of the outer wall of the turntable 4. The threaded rod 15 is threadedly sleeved inside the first side plate 14. The upper end of the threaded rod 15 is rotatably connected to the lower side of the sealing ring 10. A second side plate 16 is fixedly installed on the side wall of the turntable 4, on the side away from the first side plate 14. A guide rod 17 is slidably sleeved inside the second side plate 16. The upper end of the guide rod 17 is fixedly connected to the sealing ring 10, so that the sealing ring 10 can slide stably.

[0026] Reference Figure 1-3 The first transmission mechanism includes a first gear 5 and a second gear 8. The first gear 5 is fixedly mounted on the lower surface of the turntable 4 and is concentric with the turntable 4. A rotating rod 7 is rotatably mounted on one side of the upper surface of the support plate 6. The second gear 8 is fixedly sleeved on the upper end of the rotating rod 7. A first motor 9 is fixedly mounted on the lower surface of the support plate 6, and the output end of the first motor 9 is fixedly connected to one end of the rotating rod 7.

[0027] Reference Figure 1-3 The second transmission mechanism includes a lead screw 22 and a slider 21. Two vertical plates 24 are fixedly installed on one side of the upper surface of the base plate 1. The lead screw 22 is rotatably installed between the two vertical plates 24. The slider 21 is threaded onto the wall of the lead screw 22. A push rod 20 is installed above the slider 21. A fixing block 18 is fixedly installed on one side of the outer wall of the sliding sleeve 3. The two ends of the push rod 20 are rotatably connected to the corresponding slider 21 and fixing block 18 through shaft pins 19, respectively. A limit rod 23 is installed parallel to the lower side of the lead screw 22. Both sides of the limit rod 23 are fixedly connected to the corresponding vertical plate 24. The lower side of the slider 21 is movably sleeved with the limit rod 23. A second motor 25 is fixedly installed on the outer wall of one side of the vertical plate 24. The output end of the second motor 25 is fixedly connected to one end of the lead screw 22, so that the slider 21 can slide stably.

[0028] In this invention, during use, the glued paper samples to be tested are first placed into multiple placement slots on the surface of the turntable 4, ensuring that the samples cover the water outlets without obstructing the water inlets. Then, the threaded rod 15 is rotated, moving upwards along the first side plate 14, causing the sealing ring 10 to move smoothly upwards along the guide rod 17 until the lower surface of the sealing ring 10 is in contact with the upper surface of the sample, thus simultaneously fixing multiple samples and preventing sample displacement during testing. The device is then activated, and the second motor 25 drives the lead screw 22 to rotate. The lead screw 22 drives the slider 21 to move along the limiting rod 23 towards the vertical rod 2. The slider 21 pushes the push rod 20 to rotate via the shaft pin 19. The other end of the push rod 20 drives the sliding sleeve 3 to slide upwards along the vertical rod 2 via the fixing block 18. The sliding sleeve 3 drives the support plate 6 and the turntable 4 to move upwards synchronously until the water inlet 13 below the top plate 11 is precisely inserted into one of the water inlets on the turntable 4. Open the water outlet valve of water tank 12, and water is injected into the placement tank at a uniform speed through water inlet head 13, ensuring full contact with the paper sample for water resistance testing. Excess wastewater generated during the testing process is discharged through the outlet at the bottom of the placement tank to prevent water accumulation from affecting the test results. After a single sample is tested according to the preset testing time, close the water outlet valve, and the second motor 25 rotates in the reverse direction, driving the slider 21 to move in the reverse direction. The push rod 20 pulls the sliding sleeve 3 and the turntable 4 downward, and the water inlet head 13 disengages from the water inlet. Subsequently, the first motor 9 starts, driving the rotating rod 7 and the second gear 8 to rotate. The second gear 8 meshes with and drives the first gear 5 and the turntable 4 to rotate, turning the next water inlet containing a sample directly below the water inlet head 13. Repeat the above process of the second motor 25 driving the turntable 4 upward and adding water for testing, achieving continuous and uninterrupted multi-sample testing. After all samples have been tested, rotate the threaded rod 15 in the reverse direction, driving the sealing ring 10 to move downward, allowing all tested samples to be removed at once for subsequent water resistance performance evaluation, such as observing the degree of water absorption and measuring the water absorption rate. The entire testing process does not require frequent sample loading and unloading, greatly reducing downtime and significantly improving the efficiency of batch testing. At the same time, the testing conditions for multiple samples remain consistent, ensuring the accuracy and comparability of the test results.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
