Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] According to embodiments of the present invention, on the one hand, such as Figures 1 to 5 As shown, a roller adjustment device is provided, comprising: a pair of bearing plates 100, which are disposed opposite to each other on both sides of a liquid storage tank along the Y direction; a roller 800 is disposed in the liquid storage tank and the roller 800 is located between the pair of bearing plates 100; a first connecting plate 110 is provided on one of the bearing plates 100, and a first U-shaped hole 111 is provided on the first connecting plate 110; a transmission mechanism, the output end of which is connected to the roller 800; and a first adjustment component 200 connected to the first connecting plate 110. The first adjustment component 200 has a first adjustment part 210, a rotating shaft 220 and a rotating wheel 230, the rotating shaft 220 is connected to the first adjustment part 210, the rotating wheel 230 is eccentrically disposed on the rotating shaft 220, and the rotating wheel 230 is disposed in the first U-shaped hole 111.

[0021] In this embodiment, the X direction is the length direction of the liquid storage tank, the Y direction is the width direction of the liquid storage tank, and the Z direction is the height direction of the liquid storage tank. A pair of bearing plates 100 are arranged opposite each other on both sides of the liquid storage tank along the Y direction to support the roller 800. A first connecting plate 110 is connected to one of the bearing plates 100, extending outward from the outer surface of the bearing plate 100 along the Y direction. A U-shaped hole 111 is provided on the first connecting plate 110, which serves as an adjustment guide structure, allowing the component to move in a specific direction within the first U-shaped hole 111, providing displacement space for subsequent adjustment. The roller 800 is located between the two bearing plates 100. One end of the roller 800 is connected to the output end of the transmission mechanism, and the other end can be mounted on the bearing plate 100 through a structure such as a bearing, so that the roller 800 can rotate stably under the drive of the transmission mechanism.

[0022] The first adjustment assembly 200 includes a first adjustment section 210, a rotating shaft 220, a rotating wheel 230, and a third connecting plate 240. The first adjustment section 210 is the operating end of the first adjustment assembly 200, which can be an adjustment handwheel or adjustment knob, etc., for the user to input adjustment power. The end of the rotating shaft 220 is connected to the first adjustment section 210, and the rotating shaft 220 is mounted on the third connecting plate 240, so that the rotating shaft 220 and the third connecting plate 240 are threadedly connected. The third connecting plate 240 is fixedly connected to the first connecting plate 110, thereby mounting the first adjustment assembly 200 as a whole on the bearing plate 100. The rotating wheel 230 is connected to the rotating shaft 220, and the rotating wheel 230 is eccentrically mounted on the rotating shaft 220; the rotating wheel 230 is then positioned in a first U-shaped hole. Two first connecting plates 110 may be provided and installed on the bearing plate 100 along the Z direction; two rotating wheels 230 are provided and arranged on the rotating shaft 220 along the Z direction, with the two rotating wheels 230 respectively located in the first U-shaped holes 111 of the two first connecting plates 110.

[0023] When the position of roller 800 needs to be adjusted, the first adjustment part 210 is operated to drive the rotating shaft 220 to rotate. The rotating shaft 220 can transmit the rotational motion of the first adjustment part 210, thereby causing the eccentric roller 230 to rotate around the center of the rotating shaft 220. Due to the eccentricity of the roller 230, the edge of the roller 230 will push or pull relative to the first U-shaped hole 111 during rotation. The first U-shaped hole 111 restricts the direction of movement of the roller 230, so the eccentric rotation of the roller 230 will be converted into the linear displacement of the first connecting plate 110. This causes the first connecting plate 110 to drive the lateral movement of the bearing plate 100, ultimately realizing the position adjustment of roller 800 in the liquid storage tank.

[0024] By setting a first adjustment component 200 on one side of the roller 800, and through the cooperation between the first adjustment component 200 and the first connecting plate 110 and the bearing plate 100, the overall displacement of the roller 800 is precisely controlled, effectively eliminating the running gap of the roller 800, significantly reducing the intensity of manual intervention. Compared with the traditional double-sided adjustment mode, this utility model can reduce the manual calibration process, make the adjustment process simpler, avoid multiple rework, and effectively improve the adjustment efficiency of the roller 800.

[0025] like Figure 6 , Figure 7 As shown, in one embodiment, a pair of tracks 300 are also included, which are fixedly disposed on both sides of the bearing plate 100 along the X direction. The track 300 has a protrusion 310 on the side facing the bearing plate 100, and the bearing plate 100 has grooves 120 on both sides. The protrusion 310 is located in the groove 120, so that the bearing plate 100 moves relative to the track 300.

[0026] In this embodiment, a pair of rails 300 are fixedly installed along the X direction and located on both sides of the bearing plate 100, so that the pair of rails 300 can support the bearing plate 100 along the Z direction. A protrusion 310 is provided on the side of the rail facing the bearing plate 100, and corresponding grooves 120 are provided on both sides of the bearing plate 100, so that the protrusion 310 is embedded in the groove 120, realizing a sliding fit between the bearing plate 100 and the rails 300, allowing the bearing plate 100 to move relative to the rails 300. When the bearing plate 100 is supported by the two rails 300, a space is reserved between the two rails 300 along the X direction for the bearing plate 100 to move laterally, facilitating the adjustment of the bearing plate 100 and the roller 800 connected to the bearing plate 100. The protrusion 310 can be provided in two parts, and two grooves 120 are provided on both sides of the bearing plate 100. The two protrusions 310 of the track 300 are placed in the two grooves 120 so that the track 300 can better support the bearing plate 100.

[0027] The engagement between the protrusion 310 and the groove 120 restricts the freedom of movement of the bearing plate 100, ensuring that it can only translate along the X direction of the track 300, and cannot deviate in the Y direction, nor rotate or tilt around the Z axis. This ensures that when the bearing plate 100 drives the roller 800 for adjustment, the movement trajectory of the roller 800 is a straight line along the X direction, preventing the roller 800 from shifting position due to adjustment operations and guaranteeing the relative positional accuracy of the roller 800 with other components in the liquid storage tank.

[0028] In one embodiment, a pair of second adjusting components 400 are further included, disposed opposite each other on the bearing plate 100 along the Y direction, for adjusting the height of the roller 800. Further, each second adjusting component 400 has a second adjusting part 410, a lead screw 420, a lead screw nut, and a second connecting plate 430. The lead screw 420 is connected to the second adjusting part 410 and to the second connecting plate 430, which is fixedly connected to the bearing plate 100. The lead screw nut is sleeved on the lead screw 420 and connected to the roller 800.

[0029] In this embodiment, along the Y direction, a pair of second adjusting components 400 are located on both sides of the liquid storage tank and are arranged opposite to each other on the bearing plate 100 for adjusting the height of the roller 800. Specifically, the second adjusting component 400 has a second adjusting part 410, a lead screw 420, a lead screw nut, and a second connecting plate 430; the second adjusting part 410 is the operating end of the second adjusting component 400, used to input rotational power to drive the lead screw 420 to rotate. The end of the lead screw 420 is connected to the second adjusting part 410, and then the lead screw 420 is connected to the second connecting plate 430. The second connecting plate 430 is fixed to the bearing plate 100, providing rotational support for the lead screw 420, so that the lead screw 420 can rotate freely within the second connecting plate 430, but the axial position of the lead screw 420 is relatively fixed. The lead screw nut is sleeved on the lead screw 420 and meshes with it. When the lead screw 420 rotates, the lead screw nut will move linearly along the axial direction (i.e., the height direction) of the lead screw 420. At the same time, since the lead screw nut is connected to the roller 800, the lead screw nut can directly drive the roller 800 to move synchronously, so as to realize the adjustment of the roller 800 in the height direction.

[0030] Meanwhile, since a second adjustment component 400 is installed on both sides of the bearing plate 100 along the Y direction, the lead screws 420 on both sides can be adjusted synchronously to ensure that the roller 800 remains horizontal during the height adjustment process, thus avoiding the roller 800 tilting due to unilateral adjustment, which would affect the fitting accuracy between the roller 800 and other components in the liquid storage tank.

[0031] like Figures 8 to 10 As shown, in one embodiment, the transmission mechanism includes a first transmission component 500 and a second transmission component 600; the first transmission component 500 is located below the liquid storage tank, and the output end of the first transmission component 500 is connected to the roller 800 in a transmission connection; the second transmission component 600 is located above the liquid storage tank, and the output end of the second transmission component 600 is connected to the other roller 800 in a transmission connection.

[0032] In this embodiment, both the first transmission assembly 500 and the second transmission assembly 600 are located outside the liquid storage tank and on the side away from the first adjustment assembly 200. The first transmission assembly 500 is located below the liquid storage tank, and its output end is connected to a roller 800 located inside the liquid storage tank at its lower end. The first transmission assembly 500 can drive the roller 800 to rotate. The second transmission assembly 600 is located above the liquid storage tank, and its output end is also connected to a roller 800 located inside the liquid storage tank at its upper end, so that the roller 800 is above the liquid surface. The second transmission assembly 600 can drive the roller 800 to rotate. By reasonably distributing the positions of the first transmission assembly 500 and the second transmission assembly 600, space is reserved for multi-directional adjustment of the roller 800, avoiding interference between the first transmission assembly 500 and the second transmission assembly 600. For example, when the lower roller 800 moves in the X direction, the first transmission component 500 below the liquid storage tank can move synchronously with the roller 800; when the upper roller 800 adjusts its height, the upper second transmission component 600 can adapt to the height change through a structure such as the lead screw 420.

[0033] In one embodiment, the first transmission assembly 500 includes a first mounting base 510, a first gear set 520, and a magnetic element 530. The first gear set 520 is mounted on the first mounting base 510, and the output end of the first gear set 520 is connected to the magnetic element 530. The roller 800 is magnetically connected to the magnetic element 530.

[0034] In this embodiment, the first mounting base 510 serves as the basic support structure of the first transmission assembly 500, used to fix the first gear set 520 and the magnetic component 530, ensuring the relative position stability of the two and providing a rigid mounting reference for the entire first transmission assembly 500, thus preventing component displacement due to vibration during operation. The first gear set 520 consists of multiple meshing gears, used to receive the rotational power output from the drive motor and transmit the rotational power to the output end of the first gear set 520.

[0035] The magnetic component 530 is connected to the output end of the first gear set 520, allowing it to rotate synchronously with the gear set 520. The magnetic component 530 itself possesses strong magnetism and can generate a stable magnetic field. The roller 800 is magnetically connected to the magnetic component 530, ensuring no rigid contact between them; power transmission is achieved through magnetic force coupling. When the magnetic component 530 rotates, its magnetic field drives the roller 800 to rotate synchronously. It is understood that the roller 800 may have a built-in magnetic component or be made of a magnetically conductive material to facilitate synchronous rotation with the magnetic component 530.

[0036] The first transmission component 500 is located below the liquid storage tank, while the roller 800 is inside the tank and in direct contact with the liquid. If a traditional rigid transmission is used, with the transmission shaft passing through the tank wall to connect the roller 800, a complex sealing structure is required at the shaft hole in the tank wall. This sealing structure is prone to wear and leakage, posing a risk of seepage. By installing the magnetic component 530 outside the tank and placing the roller 800 inside, the magnetic field of the magnetic component 530 can penetrate the tank wall to transmit force, thus achieving a magnetic connection between the magnetic component 530 and the roller 800. This eliminates the need for holes in the tank wall, fundamentally avoiding the risk of leakage.

[0037] In one embodiment, the second transmission assembly 600 includes a second mounting base 610, a second gear set 620, and a universal coupling 630. The second gear set 620 is mounted on the second mounting base 610, and the output end of the second gear set 620 is connected to the universal coupling 630. The roller 800 is connected to the universal coupling 630 in a transmission connection.

[0038] In this embodiment, the second mounting base 610 serves as the basic support structure of the second transmission assembly 600, used to fix the second gear set 620 and the universal coupling 630, ensuring the relative position stability of the two and providing a rigid mounting reference for the second transmission assembly 600, preventing component displacement due to vibration or adjustment during operation. The second gear set 620 consists of multiple meshing gears, used to receive the rotational power output from the drive motor and transmit the rotational power to the output end of the second gear set 620.

[0039] Universal coupling 630 is connected to the output end of the second gear set 620, allowing it to rotate synchronously with the second gear set 620. As a flexible power transmission connector, universal coupling 630 allows for angular and radial displacement of the two shafts within a certain range and can stably transmit torque. The other end of universal coupling 630 is directly connected to the shaft of the upper roller 800, thereby transmitting the rotational power of the second gear set 620 to the roller 800, driving it to rotate. When adjusting the position of the roller 800, coaxiality deviations may occur between the roller 800 shaft and the output shaft of the second gear set 620, such as angular tilting due to height adjustment or radial offset due to horizontal movement. The angular compensation capability of universal coupling 630 can directly absorb these deviations, preventing jamming, wear, or breakage of the rigid connection due to deviations, ensuring uninterrupted power transmission during adjustment.

[0040] Furthermore, the first mounting base 510 is provided with a second U-shaped hole 511 for adjusting the position of the first gear set 520; the second mounting base 610 is provided with a third U-shaped hole 611 for adjusting the position of the second gear set 620.

[0041] Specifically, a second U-shaped hole 511 is provided on the first mounting base 510, and a third U-shaped hole 611 is provided on the second mounting base 610. The position of the mounting base can be adjusted through the U-shaped hole, thereby adjusting the relative position of the gear set. The gear set is mounted on the mounting base, and then fasteners pass through the U-shaped holes to fix and lock the mounting base. After loosening the fasteners, the mounting base can be moved along the extension direction of the U-shaped hole to achieve fine-tuning of the position. After adjustment, the fasteners are tightened again to fix the mounting base. By fine-tuning the position of the mounting base through the U-shaped hole, the relative position of the gear set can be adjusted, so that after adjusting the roller 800, the output end of the gear set can be coaxial with the axis of the roller 800.

[0042] For the first gear set 520, when the roller 800 changes position via the track 300 or the adjusting assembly, the position of the first gear set 520 can be finely adjusted through the second U-shaped hole 511 to ensure the magnetic coupling accuracy between the magnetic component 530 and the roller 800. For the second gear set 620, when the roller 800 adjusts its height or horizontal position, the position of the second gear set 620 can be finely adjusted through the third U-shaped hole 611 to reduce the compensation pressure on the universal coupling 630 and ensure transmission stability. The extension direction of the U-shaped hole can be set according to actual usage requirements.

[0043] In one embodiment, a flexible coupling 900 is also included, connected to a plurality of second transmission components 600.

[0044] In this embodiment, the second transmission assembly 600 is used to transmit driving force to the rollers 800 above the liquid storage tank. Since there are multiple rollers 800 along the X direction, there are multiple second transmission assemblies 600, each corresponding to one of the multiple rollers 800. Although the multiple second transmission assemblies 600 are arranged in the same direction, due to limitations such as machining errors, installation accuracy, or the adjustment of the rollers 800, the shaft systems of each second transmission assembly 600 may experience slight radial, axial, or angular deviations. When the multiple rollers 800 change position synchronously through the adjustment assembly, the multiple second transmission assemblies 600 will produce coordinated displacement changes with the rollers 800. The flexible coupling 900 can compensate for the slight deviations during the displacement process in real time, ensuring uninterrupted power transmission; moreover, the segmented connection of the flexible coupling 900 is more flexible and facilitates individual maintenance of a specific transmission assembly.

[0045] In one embodiment, a timing belt 700 is also included, and a roller 800 located below the liquid storage tank is connected to a roller 800 located above the liquid storage tank via the timing belt 700.

[0046] In this embodiment, the synchronous belt 700 has teeth on its surface, which mesh with the synchronous belt pulley 700 on the roller 800 shaft to facilitate power transmission and ensure that the two rollers 800 rotate at the same speed and coordinate their directions. Furthermore, the synchronous belt 700 itself has a certain degree of flexibility, which can absorb minor radial or angular deviations caused by adjustments to the two rollers 800, preventing jamming or wear caused by displacement in the rigid connection. Simultaneously, the flexible transmission can buffer the vibration of the rollers 800 during operation, reducing the impact load on the transmission system and protecting components such as the synchronous belt 700 and gear sets.

[0047] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0048] The specific embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
