[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figures 1 to 5 As shown in the figure, this utility model discloses a water absorption device, including a pressing module 300, a support module 400, a water absorption module 500, a first pressing block mounting base 100, and a second pressing block mounting base 200. The support module 400 can selectively fix the relative distance between the first pressing block mounting base 100 and the second pressing block mounting base 200 along the pressing direction; the pressing module 300 includes a pressing member 310 and an elastic member 320, the pressing member 310 includes an integrally formed pressing block 311 and a mounting rod 312, the pressing block 311 is slidably disposed on the second pressing block mounting base 200 along the pressing direction; the water absorption module 500 includes two water absorption rollers 510, one of which is connected to the second pressing block. The mounting base 200 is rotatably connected, and another suction roller 510 is rotatably connected to the clamping block 311. The two suction rollers 510 abut against each other in the clamping direction, and the workpiece to be deliquified can be inserted between the two suction rollers 510 and rotate relative to each other. The mounting rod 312 is movably inserted through the first clamping block mounting base 100, and the elastic element 320 is movably sleeved outside the mounting rod 312. One end of the elastic element 320 abuts against the clamping block 311, and the other end of the elastic element 320 abuts against the first clamping block mounting base 100. The suction roller 510 on the sliding side cooperates with the clamping module 300, and is linked to the suction roller 510 on the other side that cooperates with the support module 400 to adjust the initial position. This allows it to be used for workpieces of different thicknesses to be deliquified, and the clamping force of the two suction rollers 510 on the workpiece to be deliquified can be adjusted. Even through thinner workpieces, the suction rollers 510 can still make full contact with the workpiece to be deliquified and stably complete the deliquification.

[0039] Due to the influence of elastic force, the clamping block 311 can move with the suction roller 510. When the workpiece to be dehydrated passes between the two suction rollers 510, the clamping block 311 can still stably apply pressure to the suction roller 510 on the sliding side, so that the two suction rollers 510 maintain a stable distance and clamping force. It can adapt to workpieces of different thicknesses and specifications, and adaptively adjust the clamping force, so that the dehydration effect is always in good condition. The clamping module 300 and the support module 400 independently control the suction rollers 510 on both sides, and the clamping function is set in the non-suction working part of the suction device, avoiding structural restrictions on the working direction of the suction roller 510. The structure is simple and convenient for quick disassembly, assembly, replacement and maintenance.

[0040] Specifically, such as Figure 3 and Figure 4 As shown, the support module 400 includes a support member 410, with both ends of the support member 410 selectively connected to the first pressure block mounting base 100 and the second pressure block mounting base 200, respectively. The second pressure block mounting base 200 is provided with a fixing groove, and one end of the support member 410 is provided with a mounting clip 420. The mounting clip 420 can be placed within the fixing groove to fix the support member 410 to the second pressure block mounting base 200. Exemplarily, a fixing nut 421 is also provided on the support rod. After the mounting clip 420 engages with the second pressure block mounting base 200, rotating the fixing nut 421 gradually tightens the fixing nut 421 simultaneously with both the mounting clip 420 and the second pressure block mounting base 200, further ensuring the stability of the support module 400 assembly.

[0041] Optionally, the other end of the support member 410 can pass through the first pressure block mounting base 100 and is provided with an adjusting member 430. The adjusting member 430 can control the first pressure block mounting base 100 to move closer to the second pressure block mounting base 200. In this embodiment, the adjusting member 430 includes an adjusting nut 431 and a locking nut 432. The adjusting nut 431 is threadedly connected to the support member 410 and abuts against the first pressure block mounting base 100. The locking nut 432 can lock the adjusting nut 431 in the opposite direction. After rotating the lower adjusting nut 431 to bring the first pressure block mounting base 100 and the second pressure block mounting base 200 to a set distance, the upper locking nut 432 is rotated in the opposite direction to lock it, thus quickly completing the initial adjustment of the water suction device.

[0042] For example, the first pressure block mounting base 100 is provided with a snap-fit ​​groove 101. The slotting direction of the snap-fit ​​groove 101 is perpendicular to the extension direction of the support member 410. Part of the support member 410 can be placed in the snap-fit ​​groove 101 so that the adjusting nut 431 abuts against the top of the snap-fit ​​groove 101, which facilitates the quick assembly of the first pressure block mounting base 100 and the support module 400.

[0043] Specifically, such as Figure 4 and Figure 5As shown, the suction roller 510 includes a working part 511, a neck 512, and a locking part 513 that are sequentially connected and integrally formed. The two suction rollers 510 extend axially and are arranged parallel to each other, perpendicular to the pressing direction. The axial length of the suction rollers is ensured to be greater than the width of the workpiece to be dehydrated. The second pressure block mounting base 200 is provided with a pressing groove 201. The neck 512 is slidably placed in the pressing groove 201 along the pressing direction, so that the suction roller 510 can rotate freely in the pressing groove 201 through the neck 512. The outer diameter of the working part 511 and the outer diameter of the locking part 513 are both greater than the groove width of the pressing groove 201. The opposite sides of the working part 511 and the locking part 513 are parallel and locked at both ends of the pressing groove 201, maintaining the relative parallelism and stability of the two suction rollers 510 during dehydration, further ensuring a good dehydration effect.

[0044] It is understandable that multiple clamping modules 300 are provided on the water suction device, and the water suction modules 500 and the clamping modules 300 are set one-to-one. The two water suction rollers 510 of each water suction module 500 have the same contact height. That is, multiple clamping modules 300 are arranged in sequence. The movement path of the workpiece to be dehydrated is to be inserted between each water suction module 500 in sequence and in a straight line. The multiple dehydration design ensures a stable dehydration effect.

[0045] Optionally, the outer diameter of the two suction rollers 510 of each suction module 500 is the same. The suction modules 500 can be divided into various types according to the outer diameter specifications of the suction rollers 510. Multiple suction modules 500 can be set on the suction device to ensure a comprehensive liquid removal effect on the workpiece to be removed.

[0046] In this embodiment, multiple support modules 400 are also provided. The multiple support modules 400 can be arranged at intervals to ensure the assembly stability and parallelism of the first pressure block mounting seat 100 and the second pressure block mounting seat 200; or, adjacent support modules 400 can adjust the relative distance between the first pressure block mounting seat 100 and the second pressure block mounting seat 200 along the pressing direction to gradually decrease, so that the initial pressing force of each water absorption module 500 gradually increases, further improving the liquid removal efficiency.

[0047] like Figure 1 , Figure 2 and Figure 4 As shown, the first pressure block mounting base 100 is provided with an adjustment hole 102, and a detachable retaining ring 330 is also sleeved on the mounting rod 312. The end of the mounting rod 312 away from the pressure block 311 passes through the adjustment hole 102 before the retaining ring 330 is installed. The outer diameter of the retaining ring 330 is larger than the inner diameter of the adjustment hole 102, which can prevent the pressure member 310 from disengaging from the first pressure block mounting base 100, and further ensure the assembly stability of the pressure module 300 and the first pressure block mounting base 100.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
