It is mainly used to ensure that printed materials can maintain the integrity and clarity of the ink layer after being exposed to moisture during storage or transportation.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0034] like Figure 1-3 As shown, a wet tack resistance testing device for water-based ink includes a frame assembly 1 and a pressing assembly;

[0035] The frame assembly 1 includes a top plate 11 and a bottom plate 12 arranged in parallel. Support rods 13 are provided around the outer perimeter of the top plate 11 and the bottom plate 12. A test sample placement area 12a is provided in the middle of the bottom plate 12.

[0036] The pressing assembly includes a driving mechanism 2 and a pressing mechanism 3. The pressing mechanism 3 is located above the test sample placement area 12a. The pressing mechanism 3 includes an upper connecting block 31, an elastic element 32 and a lower connecting block 33 arranged coaxially from top to bottom.

[0037] The two ends of the elastic element 32 are fixedly connected to the upper connecting block 31 and the lower connecting block 33, respectively;

[0038] A guide mechanism 4 is provided between the upper connecting block 31 and the lower connecting block 33 and the support rods 13 on the outer periphery. The guide mechanism 4 is used to prevent the upper connecting block 31 and the lower connecting block 33 from radially shifting when they move up and down.

[0039] The driving mechanism 2 is connected to the top plate 11, and the driving end is located on the upper surface of the upper connecting block 31. The driving mechanism 2 is used to drive the pressing mechanism 3 to move towards the bottom plate 12.

[0040] Working principle: During testing, multiple stacked test samples are first placed in the test sample placement area 12a. Then, they are pre-positioned under the pre-pressing of the pressing mechanism 3. After the test samples are placed, the driving mechanism 2 drives the driving end to move closer to the upper connecting block 31. This applies pressure to the stacked test samples through the pressing mechanism 3. After reaching the set pressure value, the samples are left to stand for a certain period of time. Then, the test samples are taken out. The anti-wet adhesion performance is judged by observing whether the ink layer of the test sample sticks or falls off. This allows for simultaneous testing of multiple test samples, which is efficient and easy to operate.

[0041] Furthermore, such as Figure 1 , 2 As shown in Figure 3, the pressing mechanism 3 also includes a scale 34, which is located on one side of the elastic element 32. The scale 34 has a groove 34a extending from one end to the other. One end of the scale 34 is fixedly connected to the lower connecting block 33.

[0042] A slider 5 is provided on one side of the upper connecting block 31. The slider 5 passes through the slide groove 34a and is slidably connected to the slide groove 34a.

[0043] In this embodiment, when subjected to pressure, the elastic element 32 is compressed, and the upper connecting block 31 and the slider 5 move downward relative to the scale 34. At this time, the slider 5 acts as a scale pointer, and the magnitude of the applied pressure is determined according to the scale corresponding to the slider 5. This achieves effective characterization of pressure while also precisely controlling the applied pressure.

[0044] like Figure 1 As shown, in Embodiment 1: the driving mechanism 2 is a threaded pressure rod, one end of which passes through the threaded hole of the top plate 11 and is located above the upper connecting block 31, and the other end is provided with a handle 6.

[0045] In this embodiment, the threaded pressure rod is driven to move closer to the pressing mechanism 3 by rotating the handle 6, thereby applying pressure to the pressing mechanism 3. The structural design of the threaded pressure rod combined with the elastic element 32 has a wider test pressure range and can meet more test requirements.

[0046] like Figure 3 As shown, in Embodiment 2, in order to save effort and control pressure more precisely, the driving mechanism 2 is a linear actuator, and the driving end of the linear actuator is connected to the upper connecting block 31; the pressure is applied to the pressing mechanism 3 through the driving end of the linear actuator, thereby realizing the application of a heavy object to simulate pressure on the test sample.

[0047] Furthermore, such as Figure 1 , 3 As shown, in order to avoid the upper connecting block 31 and the lower connecting block 33 from twisting or shifting when subjected to force, thus dispersing the pressure and affecting the accuracy of the applied pressure, the guide mechanism 4 includes a connecting rod 41 that corresponds one-to-one with the support rod 13. The connecting rod 41 is perpendicular to the support rod 13. One end of the connecting rod 41 is connected to the upper connecting block 31 or the lower connecting block 33, and the other end is provided with a sliding sleeve 42 that is slidably sleeved with the support rod 13.

[0048] In this embodiment, in order to simplify the structure and improve the overall integrity, the connecting rod 41 and the sleeve are integrally formed with the upper connecting block 31 or the lower connecting block 33.

[0049] Furthermore, such as Figure 1 , 3 As shown, it also includes an ejection mechanism 7 connected to the base plate 12. The ejection mechanism 7 is located on one side of the test sample placement area 12a and is used to remove the test sample that has completed the test from the base plate 12.

[0050] Furthermore, such as Figure 1 , 3 As shown, in order to remove the test sample without direct contact, the ejection mechanism 7 includes a connecting seat 71 and a push rod 72; the connecting seat 71 is disposed on the bottom plate 12 on one side of the test sample placement area 12a, and a through sliding hole 71a is provided on the connecting seat 71.

[0051] The push rod 72 is slidably disposed in the sliding hole 71a, with one end of the push rod 72 facing the test sample placement area 12a and the other end extending outward.

[0052] In this embodiment, before the test sample is ejected, the pressing mechanism 3 resets upward along with the driving mechanism 2.

[0053] Furthermore, such as Figure 1 , 3As shown, in order to facilitate and effectively remove the test sample, the push rod 72 is provided with a push plate 73 at one end near the test sample placement area 12a, and a handle 74 at the other end.

[0054] Furthermore, the elastic element 32 is one or a combination of a spring or elastic rubber.

[0055] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
