Description

Technical Field

[0001] This application relates to the field of alumina plate cleaning technology, specifically a roller brush assembly for cleaning alumina plates. Background Technology

[0002] In modern continuous production lines for alumina sheets, surface cleaning is a crucial process, directly impacting the quality and yield of subsequent processes such as spraying, lamination, and sheet metal fabrication. Currently, the industry commonly employs a multi-roller brush system working in conjunction with a high-pressure spray system. In this system, roller brush assemblies installed at different stations rotate at high speed driven by motors, while the spray device simultaneously sprays cleaning agents or water. Through a combination of physical friction and chemical action, oil, metal dust, oxide film residue, and other process contaminants are effectively removed from the aluminum sheet surface.

[0003] However, as consumable parts, roller brushes gradually wear down, deform, or accumulate stubborn dirt under continuous high-intensity friction, leading to a decrease in cleaning effectiveness and requiring periodic replacement or disassembly for cleaning. Existing roller brush assemblies typically employ an integral or tandem design, with each brush installed in a compact and interconnected manner. When a single roller brush reaches the end of its service life or requires maintenance, it cannot be replaced independently; the entire cleaning line must be shut down and powered off before any operation can proceed. For modern production lines that prioritize high efficiency and continuous operation, this results in unplanned downtime, production interruptions, and significant losses in time and economic costs.

[0004] Meanwhile, the replacement process is cumbersome, especially the lower roller brush, which requires professional maintenance personnel to use various tools and spend a considerable amount of time to complete. This increases the labor intensity for workers and prolongs downtime. Utility Model Content

[0005] This application, through its modular and independently detachable structural design, enables rapid replacement and flexible adjustment of the roller brush, significantly improving the maintenance efficiency and ease of operation of the alumina plate cleaning equipment, and effectively solving the problems in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a roller brush assembly for cleaning alumina plates, comprising:

[0007] The circular frame has a notch in the middle of its outer side and multiple mounting shafts on its inner side. The mounting shafts are rotatably connected to the circular frame through bearings.

[0008] At least one pair of roller brushes, including an upper roller brush and a lower roller brush, are mounted on different mounting shafts and secured with fasteners.

[0009] The drive mechanism includes a motor mounting bracket and a geared motor, wherein the output shaft of the geared motor is connected to a mounting shaft via a coupling.

[0010] The transmission mechanism, located on the outside of the ring frame, is used to transmit power to another mounting shaft;

[0011] A moving mechanism, located below the spiral frame, is used to support and move the roller brush assembly.

[0012] Preferably, the transmission mechanism includes: an outer casing fixed to the outside of the U-shaped frame; a driving pulley and at least one driven pulley, respectively mounted on two mounting shafts;

[0013] A belt is fitted between the driving pulley and the driven pulley.

[0014] Preferably, the moving mechanism includes: a base, the lower surface of which is provided with a plurality of casters;

[0015] Multiple stud support legs are fixed to the upper surface of the base and pass through the through holes on the lower surface of the U-shaped frame;

[0016] The positioning nut is used to secure the stud support leg to the retaining frame.

[0017] Preferably, the outer edge of the spiral frame is provided with at least one threaded through hole for fixing the position of the roller brush assembly.

[0018] Preferably, the number of mounting shafts is four, arranged in pairs, for mounting the upper roller brush and the lower roller brush respectively.

[0019] Preferably, the axes of the upper roller brush and the lower roller brush coincide with the axis of the corresponding mounting shaft.

[0020] Preferably, the geared motor is fixed to the side of the U-shaped frame by a motor mounting bracket.

[0021] Preferably, it also includes a control switch for controlling the start, stop and speed of the geared motor.

[0022] Compared with the prior art, the beneficial effects of this application are:

[0023] 1. This application, by adopting a U-shaped frame in conjunction with a multi-axis mounting structure, enables the independent installation and disassembly of the upper and lower roller brushes. This allows for the individual replacement or maintenance of a single roller brush without affecting the overall operation of the equipment, greatly reducing downtime and improving the continuity and efficiency of the production line.

[0024] 2. The moving mechanism and height-adjustable support legs design make the entire roller brush assembly easy to move and position. At the same time, it can be quickly fixed through the threaded through holes, which enhances the stability and adaptability of the equipment during the cleaning process and is suitable for different work positions and cleaning environments.

[0025] 3. The transmission mechanism adopts a closed belt drive, which is compact in structure and smooth in transmission. It is combined with a geared motor to provide reliable power, which not only ensures the uniformity and effect of roller brush cleaning, but also reduces operating noise and maintenance frequency, and improves the overall durability and economy of the equipment.

[0031] Please see Figure 1-2 This application provides the following technical solution: a roller brush assembly for cleaning alumina plates, comprising:

[0032] The U-shaped frame 3 has a notch 4 in the middle of its outer side. The notch allows the roller brush assembly to pass through the aluminum plate and the conveyor roller to enter and exit the cleaning area without interference. Multiple mounting shafts 11 are rotatably connected to the inner side through bearings. This arrangement makes the roller brush evenly stressed and runs smoothly. Each roller brush can be disassembled and installed independently, which greatly simplifies the maintenance process.

[0033] At least one pair of roller brushes, including an upper roller brush 2 and a lower roller brush 8, are respectively mounted on different mounting shafts 11 and reliably fixed by bolts or other fasteners. This opposing layout can simultaneously brush the upper and lower surfaces of the aluminum plate, resulting in high cleaning efficiency. Furthermore, the roller brushes are coaxially set with the mounting shafts, ensuring smooth operation and minimal wear.

[0034] The drive mechanism includes a motor mounting bracket 1 and a geared motor 10. The output shaft of the geared motor 10 is connected to a mounting shaft 11 via a coupling to provide stable power input. The speed is adjustable to adapt to different cleaning process requirements.

[0035] The transmission mechanism 9 is located on the outside of the rotating frame 3 and is used to transmit power to another mounting shaft 11 to achieve synchronous drive of the two rollers and ensure that the cleaning action is coordinated and consistent.

[0036] The moving mechanism, located below the U-shaped frame 3, is used to support and move the roller brush assembly, facilitating flexible equipment scheduling and workstation adjustment, and improving the adaptability of the production line layout.

[0037] Furthermore, the transmission mechanism 9 includes: an outer shell 93, fixed to the outside of the U-shaped frame 3, which protects and seals the internal transmission components, extending their service life; a driving pulley 94 and at least one driven pulley 91, respectively mounted on two mounting shafts 11; and a belt 92, which tensions and connects the driving pulley 94 and the driven pulley 91. This belt transmission method has a simple structure, smooth transmission, low noise, and is easy to adjust tension and maintain.

[0038] Furthermore, the moving mechanism includes: a base 7, the lower surface of which is provided with multiple casters 12, which can make the equipment easy to move and turn; multiple stud support legs 5, which are fixed to the upper surface of the base 7, pass through the through holes on the lower surface of the ring frame 3, and can be adjusted by screwing; and positioning nuts 6, which are used to lock the stud support legs 5 to the ring frame 3 to ensure that the equipment is stable and does not shift when it is working.

[0039] Furthermore, the outer edge of the spiral frame 3 is provided with at least one threaded through hole, which can be connected to external equipment or foundation by bolts to further reinforce the position of the roller brush assembly and prevent displacement or vibration during the cleaning process.

[0040] Furthermore, there are four mounting shafts 11, arranged in pairs, for mounting the upper roller brush 2 and the lower roller brush 8 respectively. This symmetrical layout ensures a balanced distribution of brushing force and good consistency in cleaning quality.

[0041] Furthermore, the axes of the upper roller brush 2 and the lower roller brush 8 coincide with the axis of the corresponding mounting shaft 11 to avoid additional vibration, wear or power loss caused by eccentric operation.

[0042] Furthermore, the geared motor 10 is fixed to the side of the U-shaped frame 3 by the motor mounting bracket 1, which has a compact structure, short power transmission path, high efficiency, and stable installation, reducing operating vibration.

[0043] Furthermore, it also includes a control switch for controlling the start, stop and speed of the geared motor 10. Operators can flexibly adjust the scrubbing intensity according to the degree of contamination of the aluminum plate and the cleaning requirements, thereby improving process adaptability and cleaning effect.

[0044] In use: First, move the entire roller brush assembly to the predetermined position on the cleaning production line by pushing the casters 12 under the base 7. After rough positioning, place the external hydraulic jack directly under the rotating frame 3 and use the hydraulic jack to raise the rotating frame 3 to a suitable height. Finely adjust the height of the rotating frame 3 so that the gap between the upper roller brush 2 and the lower roller brush 8 matches the thickness of the alumina plate to be cleaned, and ensure that the brushing pressure is moderate. Finally, fix the height of the rotating frame 3 by rotating the positioning nuts 6 on each stud support leg 5. Then, use external bolts to pass through the threaded through holes on the outside of the rotating frame 3 to firmly connect the assembly to the foundation of the cleaning line equipment.

[0045] The alumina plate is moved on the cleaning line by the conveyor rollers. When the alumina plate moves between the upper roller brush 2 and the lower roller brush 8, the spraying equipment is started, and the cleaning agent is sprayed onto the upper and lower surfaces of the alumina plate. The reduction motor 10 is started, and the reduction motor 10 drives the upper roller brush 2 and the lower roller brush 8 to rotate and clean the surface of the alumina plate. The speed of the reduction motor 10 is finely adjusted in real time by the control switch to change the brushing intensity and obtain the best cleaning effect.

[0046] If a roller brush is found to be severely worn or needs cleaning after the equipment has been running for a period of time, it can be replaced independently by following these steps: turn off the reduction motor 10, remove the connecting bolts between the retractable frame 3 and the cleaning line, then pull out the retractable frame 3 as a whole, remove the connecting bolts between the upper roller brush 2 or the lower roller brush 8 and the mounting shaft 11, remove the upper roller brush 2 or the lower roller brush 8, fix the new roller brush on the mounting shaft 11, push the retractable frame 3 back to the cleaning station and fix it.

[0047] The notch 4 on the folding frame 3 is just enough to allow the conveyor roller and the alumina plate to pass through.

[0048] During the disassembly and replacement of a single cleaning roller assembly, the cleaning efficiency can be improved by changing the rotation speed of other cleaning roller assemblies, thus not affecting the overall cleaning effect of the cleaning line.

[0049] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
