Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0022] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0023] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] See Figure 1This utility model provides a device for detecting the water absorption rate of non-uniform diameter paper, including a base 1, a water absorption device and a water removal device located on the base 1. The water absorption device includes a support frame arranged opposite to each other and a rotating shaft 22 movably connected to the support frame. A water storage component 23 is movably connected to the rotating shaft 22. A fixing device 3 and a cover plate 4 connected to the fixing device 3 are installed above the water storage component 23. The cover plate 4 is interference-fitted with the water storage component 23, and the interference-fitted cover plate 4 effectively seals the water inside the water storage component 23, ensuring complete soaking of the subsequent paper. Figure 3 As shown, the support frame includes an upper support 211 and a lower support 212, and the upper support 211 and the lower support 212 are provided with matching limiting holes 213 and limiting members. The rotating shaft 22 is provided with a receiving space for accommodating a water storage component 23, and the water storage component 23 moves within the receiving space. The limiting holes 213 and the limiting members are used to effectively adjust the positions of the upper support 211 and the lower support 212, thereby realizing the water immersion rotation of papers of different diameters and improving work efficiency. The limiting members can be pins or pins. The water removal device includes a roller 51 that is tightly fitted to the base 1, a handle 52 that is movably connected to the roller 51, and an upper limit groove 11 located on the base 1. The roller 51 moves within the limiting groove 11, and the limiting groove 11 effectively limits the position of the roller 51, facilitating the movement of the roller 51 in the actual process and realizing the effective squeezing of water from the paper.

[0025] Preferably, such as Figure 2 As shown, the fixing device 3 of this utility model includes a connecting rod 31 and a top rod 32 screwed to the connecting rod 31. One end of the top rod 32 is equipped with a rotating handle, and the other end is equipped with a limiting head. The limiting head is used to lock the cover plate 4, which facilitates the fixing of the cover plate 4 and prevents it from sliding, thus effectively improving work efficiency and work safety.

[0026] In addition, the end of the rotating shaft 22 of this utility model is axially connected to the bracket 211, and the upper bracket 211 is equipped with a fixing bolt 6. The rotating shaft 22 is provided with a through hole that matches the fixing bolt 6. By using the fixing bolt 6 and the matching through hole, the position of the rotating shaft 22 after rotation is limited, which facilitates effective rotation and thus ensures the water immersion efficiency and water immersion quality of the paper.

[0027] Furthermore, the cover plate 4 of this utility model is provided with a groove that matches the limiting head, and a sealing element is installed in the groove. The sealing element enhances the friction between the cover plate 4 and the limiting head, thereby effectively limiting the limiting head, ensuring the position of the cover plate 4 during operation, and preventing slippage.

[0028] Better, such as Figure 4As shown, the water storage component 23 of this utility model is provided with fixing grooves 231 on both sides. The rotating shaft 22 is provided with protrusions that match the fixing grooves 231. A top bead 232 and an elastic element 233 are installed in the fixing grooves 231. The rotating shaft 22 is provided with a blind hole that cooperates with the top bead 232, and the depth of the blind hole is one-third of the diameter of the top bead 232. The top bead 232 and the elastic element 233 enable the water storage component 23 to move effectively, which facilitates the replacement of water storage components 23 of different shapes. This allows for water immersion experiments on paper of different diameters. The water storage component 23 can be manufactured according to the diameter of commonly used paper, so that it can be quickly replaced during use.

[0029] In addition, the lower support 212 of this utility model is equipped with a sliding groove to accommodate the movement of the upper support 211, and the upper support 211 is slidably connected to the lower support 212. At least two limiting holes 213 are provided. The upper support 211 and the lower support 212 with at least two limiting holes 213 can form a staggered lifting and lowering, so as to ensure effective fixing and rotation when replacing water storage components 23 of different equal diameters.

[0030] Furthermore, such as Figure 5 As shown, the limiting groove 11 of this utility model has an inclined angle and the limiting groove 11 is a smooth plane. A water outlet hole is provided at the lowest position of the limiting groove 11. The limiting groove 11 is used to place the paper, which facilitates the roller 51 to effectively squeeze and drain the paper, thereby improving the detection efficiency.

[0031] Even better, the roller 51 of this utility model is a solid metal roller, and the edge of the limiting groove 11 is provided with a baffle 12 to block the roller 51. The solid metal roller's own weight effectively squeezes the moisture in the paper, thereby enabling the paper to effectively drain water and ensuring the accuracy of the test results.

[0032] Finally, an electronic timer is installed on the base 1 of this utility model. The electronic timer enables effective timing of the paper soaking time, which facilitates the accuracy of the calculation process. The calculation is achieved by utilizing the relationship between time and water absorption. This calculation method belongs to the prior art and will not be described in detail here.

[0033] In the implementation of this invention: the paper is weighed before water absorption. After weighing, the paper is placed in the water storage container 23, and the cover plate 4 is closed. The cover plate 4 is pressed by the fixing device 3 to ensure a tight seal with the upper surface of the water storage container 23, preventing water from flowing out. Then, the water storage container 23 is rotated 180° using the rotating shaft 22, making it inverted to fully soak the paper. The soaking time is observed and timed. After the soaking time is reached, the paper is removed and placed in the limiting groove 11. The roller 51 is used to squeeze the paper up and down twice to remove excess water. The paper weight is then weighed. The water absorption rate is obtained by dividing the weight difference of the paper before and after water absorption by the time and multiplying it by the predetermined parameters of the paper. This rate is used to determine whether the water absorption requirements of the corresponding paper are met. When measuring paper of different diameters, the water storage container 23 needs to be replaced with a water storage container 23 that can support the diameter of the paper or is matched with it, and then the above process can be repeated.

[0034] In summary, a non-uniform diameter paper water absorption rate testing device includes a base, a water absorption device located on the base, and a water removal device. The water absorption device includes a support frame arranged opposite to each other and a rotating shaft movably connected to the support frame. A water storage component is movably connected to the rotating shaft. A fixing device and a cover plate connected to the fixing device are installed above the water storage component. The cover plate is interference-fitted with the water storage component, and the interference-fitted cover plate effectively seals the water inside the water storage component, ensuring complete soaking of the subsequent paper. The support frame includes an upper bracket and a lower bracket, and the upper bracket and the lower bracket are equipped with mating... The device includes a limiting hole and a limiting component. The rotating shaft has a space for accommodating a water storage component, which moves within this space. The limiting hole and limiting component allow for effective adjustment of the positions of the upper and lower supports, enabling the immersion and rotation of paper of different diameters, thus improving work efficiency. The water removal device includes a roller that is tightly fitted to the base, a handle that movably connects to the roller, and an upper limiting groove located on the base. The roller moves within the limiting groove, effectively limiting its position and facilitating its movement during operation, thereby effectively squeezing the water from the paper. The advantages of this invention are: it can effectively detect the water absorption rate of paper of different diameters, and avoid rotational inconvenience caused by different diameters, thus improving work efficiency.
