[0002] In the steel metallurgical industry, wire brush rollers are typically installed to clean the iron oxide scale from the surface of hot-rolled strip steel. Additionally, squeeze rollers are usually installed to scrub the areas of cold-rolled strip steel that require treatment. However, after a certain period of use, the wear on the brush bristles or roller surface of the brush or squeeze roller gradually increases, resulting in larger gaps between the two rollers and significantly affecting the cleaning effect.

[0003] In response, existing technologies also have gap adjustment mechanisms to adjust the gap between two brush rollers or squeeze rollers. However, due to unreasonable structural design, the synchronization of displacement is relatively poor. Utility Model Content

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] In the description of the embodiments of this utility model, 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. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0026] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, "linking" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

[0027] In the description of embodiments of this utility model, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0028] Please refer to Figures 1-5 , Figure 1 This is a structural schematic diagram of one implementation of the roller device provided in this utility model embodiment; Figure 2 for Figure 1 Schematic diagram of the middle roller gap adjustment mechanism; Figure 3 for Figure 1 A partial sectional view; Figure 4 for Figure 3 A partial enlarged view of the connection between the drive motor, the first elevator, and the connecting shaft assembly; Figure 5 for Figure 3 A magnified view of the connection between the second elevator and the connecting shaft component.

[0029] like Figure 1 As shown, this embodiment of the present invention provides a roller device, which can specifically be a wire brush roller device for cleaning iron oxide scale on the surface of hot-rolled strip steel. Alternatively, the roller device can also be a squeeze roller device for cleaning the area to be treated on the surface of cold-rolled strip steel. Alternatively, the roller device can also be a roller device with other uses, which is not limited here, as long as it has the following structure.

[0030] The roller assembly includes a roller mechanism 1000 and a roller gap adjustment mechanism 2000.

[0031] The roller mechanism 1000 may include a first roller component 1100 and a second roller component 1200 disposed opposite to each other. The component to be processed, such as hot-rolled strip steel, cold-rolled strip steel, etc., may pass between the first roller component 1100 and the second roller component 1200 so that the component to be processed is processed by at least one of the first roller component 1100 and the second roller component 1200.

[0032] The roller mechanism 1000 may further include a base frame 1300. Both the first roller component 1100 and the second roller component 1200 may be mounted on the base frame 1300, specifically by means of components such as bearing housings, to allow free rotation relative to the base frame 1300. In practical applications, the roller mechanism 1000 may further include a drive device 1400, which is capable of being driven by at least one of the first roller component 1100 and the second roller component 1200 to provide rotational driving force to both components.

[0033] For ease of description, a first direction X, a second direction Y, and a third direction Z can be defined. The first direction X is the extending direction of the first roller component 1100 and the second roller component 1200; the third direction Z is the direction in which the first roller component 1100 and the second roller component 1200 are positioned opposite each other. The first direction X and the third direction Z can be at an angle, for example, 90 degrees; the second direction Y can also be at an angle to any one of the first direction X and the third direction Z, for example, 90 degrees. (Refer to...) Figure 3 The orientation and positional relationship in the text, the third direction Z can specifically be the up and down direction.

[0034] In the first roller component 1100 and the second roller component 1200, the installation position of the second roller component 1200 relative to the base frame 1300 in the third direction Z can remain unchanged, while the first roller component 1100 can slide relative to the base frame 1300 in the third direction Z to adjust the distance between the first roller component 1100 and the second roller component 1200, so as to adapt to the thickness of the component to be processed and improve the processing effect on the component to be processed.

[0035] The roller gap adjustment mechanism 2000 can also be installed on the base frame 1300 and can be connected to the first roller component 1100 to drive the first roller component 1100 to move along the third direction Z.

[0036] Combination Figure 2 and Figure 3 The roller gap adjustment mechanism 2000 includes a drive motor 2100, a connecting shaft component 2200, and two lifting platforms. For ease of description, the two lifting platforms can be named the first lifting platform 2300 and the second lifting platform 2400, respectively. Both the first lifting platform 2300 and the second lifting platform 2400 can be screw jacks or the like. The drive motor 2100 and the first lifting platform 2300 are electrically connected. The first lifting platform 2300 and the second lifting platform 2400 are spaced apart along the axial direction of the connecting shaft component 2200. It should be understood that the axial direction of the connecting shaft component 2200 is the aforementioned first direction X. The connecting shaft component 2200 is located between the first lifting platform 2300 and the second lifting platform 2400.

[0037] Combined Figure 4 and Figure 5 The first elevator 2300 is provided with a first power transmission shaft 2310, and the second elevator 2400 is provided with a second power transmission shaft 2410. The first power transmission shaft 2310 and the second power transmission shaft 2410 can be connected to the two axial ends of the connecting shaft component 2200 respectively. The first power transmission shaft 2310, the second power transmission shaft 2410 and the connecting shaft component 2200 can rotate synchronously.

[0038] Furthermore, in this embodiment of the present invention, the roller gap adjustment mechanism 2000 further includes a tightening sleeve 2500, which is disposed between the first power transmission shaft 2310 and the connecting shaft component 2200 to achieve a tight fit between the first power transmission shaft 2310 and the connecting shaft component 2200, thereby effectively eliminating the gap between the first power transmission shaft 2310 and the connecting shaft component 2200, which is beneficial to ensuring the synchronization of displacement transmission between the first elevator 2300 and the second elevator 2400.

[0039] It should be understood that in practice, a shrink sleeve 2500 can also be provided between the second power transmission shaft 2410 and the connecting shaft component 2200; or, a shrink sleeve 2500 can be provided between both power transmission shafts and the connecting shaft component 2200, which is also feasible.

[0040] In some implementations, such as Figure 4 and Figure 5 As shown, the connecting shaft component 2200 may include a connecting shaft body 2210 and two flange sleeves, which may be referred to as the first flange sleeve 2220 and the second flange sleeve 2230, respectively.

[0041] The first flange sleeve 2220 may include a first flange connecting portion 2221 and a first socket portion 2222, with a first slot 2222A formed within the first socket portion 2222. The first flange connecting portion 2221 can be connected to the connecting shaft body 2210, for example, by bolt connection. The first power transmission shaft 2310 can be inserted into the first slot 2222A. When a shrink sleeve 2500 is provided between the first power transmission shaft 2310 and the connecting shaft component 2200, the shrink sleeve 2500 can be provided in the first slot 2222A.

[0042] The second flange sleeve 2230 may include a second flange connecting portion 2231 and a second sleeve portion 2232, with a second slot 2232A formed within the second sleeve portion 2232. The second flange connecting portion 2231 can be connected to the connecting shaft body 2210, for example, by bolt connection. The second power transmission shaft 2410 can be inserted into the second slot 2232A. When a shrink sleeve 2500 is provided between the second power transmission shaft 2410 and the connecting shaft component 2200, the shrink sleeve 2500 can be provided in the second slot 2232A.

[0043] In some implementations, the lift connected to the drive motor 2100, i.e., the first lift 2300, may have a first power transmission shaft 2310 that includes a power shaft body 2311 and a transition shaft 2312. The power shaft body 2311 can be an integral shaft of the first lift 2300, and it can be connected to the transition shaft 2312, for example, by an interference fit. The transition shaft 2312 can be connected to the connecting shaft component 2200. Figure 4 When a shrink sleeve 2500 is provided between the first power transmission shaft 2310 and the connecting shaft component 2200, the shrink sleeve 2500 may specifically be provided on the outside of the transition shaft 2312.

[0044] By adopting the above scheme, on the one hand, the transition shaft 2312 can compensate for the size of the connecting shaft component 2200 so that the connecting shaft component 2200 can be accurately connected to the power shaft body 2311. On the other hand, setting the transition shaft 2312 and the connecting shaft component 2200 to be connected can also reduce the direct wear on the power shaft body 2311. When the transition shaft 2312 is severely worn, the transition shaft 2312 can be replaced directly without replacing the entire first elevator 2300, which can effectively reduce maintenance and replacement costs.

[0045] Combination Figure 4 One end of the transition shaft 2312 can be a solid shaft portion, which is used to connect with the first sleeve portion 2222. The other end of the transition shaft 2312 can be a sleeve portion, which is used to connect with the power shaft body 2311.

[0046] In some implementations, the drive motor 2100 and the first elevator 2300 can be connected by a coupling 2600, thereby enabling power transmission between the drive motor 2100 and the first elevator 2300.

[0047] Here, the present invention does not limit the specific structural form of the coupling 2600. In practical applications, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use.

[0048] In a specific example, such as Figure 4 As shown, the coupling 2600 can be a flexible sleeve pin coupling. Flexible sleeve pin couplings have relatively few components, a relatively simple structure, and are easy to manufacture, requiring no complex gear processing machine tools. Furthermore, the structural design of the flexible sleeve pin coupling makes maintenance relatively simple; the pins made of elastic materials such as nylon can be replaced simply by removing the baffle. These elastic pins are self-lubricating and do not require lubrication, saving lubricating oil and purifying the working environment. Simultaneously, the flexible sleeve pin coupling also has good displacement compensation capabilities, allowing limited relative displacement or misalignment of the shafts of the drive motor 2100 and the first lifting platform 2300 during installation and operation, suitable for correcting angular and axial deviations.

[0049] The aforementioned flexible sleeve pin coupling may include two half-couplings 2610. The two half-couplings 2610 can be respectively connected to the drive motor 2100 and the first lifting platform 2300, and then the two half-couplings 2610 can be connected by bolts or the like. Thus, the installation process of the aforementioned flexible sleeve pin coupling can be relatively simple.

[0050] In some implementations, the roller gap adjustment mechanism 2000 provided in this utility model embodiment may also include a base 2700.

[0051] The drive motor 2100 and the two lifting platforms can be mounted on the base 2700 for integrated assembly. The roller gap adjustment mechanism 2000 can then be connected to the base frame 1300 via the base 2700, for example, by bolts. Thus, when the first roller component 1100 or the second roller component 1200 needs to be disassembled or replaced, only the base 2700 needs to be disassembled, allowing for the complete disassembly of the roller gap adjustment mechanism 2000 and the base frame 1300 without disassembling the drive motor 2100, the first lifting platform 2300, or other components within the roller gap adjustment mechanism 2000. This avoids repeated disassembly and reassembly of the components within the roller gap adjustment mechanism 2000, and the resulting reduction in the accuracy of the roller gap adjustment mechanism 2000. Furthermore, this embodiment of the invention simplifies the operation and maintenance of the roller gap adjustment mechanism 2000, ensuring high safety and production efficiency.

[0052] Here, the present invention does not limit the specific structural form of the base 2700. In practical applications, those skilled in the art can choose according to specific needs, as long as it can meet the requirements of use.

[0053] In a specific example, such as Figure 2 As shown, the base 2700 may include two base beams 2710 and two connecting beams 2720. The two base beams 2710 may be spaced apart along the axial direction (i.e., the first direction X) of the connecting shaft component 2200, and the two connecting beams 2720 may be spaced apart along the second direction Y. The two ends of the connecting beams 2720 in the first direction X may be connected to the two base beams 2710 respectively. The drive motor 2100 and the first lifting mechanism 2300 may be mounted on one base beam 2710. Figure 2 The bottom beam 2710 on the lower left side), and the second elevator 2400 can be installed on another bottom beam 2710. Figure 2 (Bottom beam 2710 on the upper right side).

[0054] In some implementations, the roller gap adjustment mechanism 2000 provided in this utility model embodiment may also include a displacement sensor 2800.

[0055] The displacement sensor 2800 mentioned above can be an ultrasonic sensor, an infrared sensor, an electromagnetic wave sensor, or other sensor that can detect distance, in order to detect the displacement distance of the first roller component 1100 along the third direction Z, thereby enabling accurate control of the position movement of the first roller component 1100.

[0056] Combination Figure 3 The displacement sensor 2800 can be mounted on the base 1300. Alternatively, it can be mounted on the base 2700. In short, the displacement sensor 2800 is acceptable as long as it achieves the technical effect of distance detection.

[0057] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
