[0002] A cold rolling mill is a new type of steel bar cold rolling processing equipment, mainly used to form thin metal sheets by cold pressing. A brush roller is a device used in a cold rolling mill. Its main function is to remove zinc and other dirt from the surface of the working roller by directly contacting the surface of the working roller. Currently, there are various self-cleaning brush roller devices for cold rolling mills on the market, but some shortcomings still exist.

[0003] For example, Chinese utility model patent CN220177851U discloses a self-cleaning brush roller device for cold rolling mills. A dustproof net and sealing ring seal and fix both ends of the brush roller sleeve. The turbine is connected to bearing supports at both ends. One end of the turbine is connected to a motor to form the transmission side, and the other end has a turbine oil inlet. A turbine oil outlet is opened on the turbine, and the turbine oil inlet and outlet are connected. Rolling oil is introduced through the turbine oil inlet via a rolling oil pipe. This device not only solves the problem of cleaning foreign matter such as aluminum-adhered layers from the surface of the support rollers, work rollers, and even the plate rollers of cold rolling mills, but also cleans the roots of the brush bristles, reducing the hassle of periodically disassembling and cleaning the brush rollers. It effectively reduces the labor intensity of workers, has significant beneficial effects, and is suitable for widespread application.

[0004] The existing technology has the following technical problems: water is poured into the turbine to make it self-clean the brush roller through the oil outlet. However, the turbine has a layer of bristles on the outside. The rotation of the brush roller alone cannot thoroughly clean the outer bristles. In addition, the cleaning water will splash and cause environmental pollution. Furthermore, the rotation of the brush roller can cause the piston to loosen from the plugged oil outlet, leading to water leakage. Therefore, we propose a self-cleaning brush roller device for cold rolling mills to solve the problems mentioned above. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Please see Figures 1-6 This utility model provides a technical solution:

[0032] To address the problems existing in the prior art, this embodiment provides the following technical solution: a self-cleaning brush roller device for a cold rolling mill, comprising a brush roller body 1; a reinforced cleaning mechanism located on the outside of the brush roller sleeve 3, which allows the brush roller sleeve 3 to rub against the friction frame 8 during rotation, resulting in more thorough cleaning of the brush roller sleeve 3; a waterproof splash mechanism located on the outside of the brush roller body 1, which controls the range of water splashed by the brush roller body 1 during rotation, preventing water from splashing and polluting the environment; and an anti-loosening mechanism located on the left side of the piston 4, which fixes the piston 4 and effectively prevents the brush roller body 1 from becoming loose during rotation.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, firstly, clean water can be poured into the interior of the brush roller body 1 from the left side. After the water enters the interior of the brush roller body 1, the piston 4 can be inserted into the left side of the brush roller body 1 to seal it. Since the connecting plate 7 is fixedly installed on the outside of the left side of the piston 4, the electric telescopic rod 6 connected to the left side of the connecting plate 7 can be opened. The output end of the electric telescopic rod 6 can pull the fixed plate 5 to the right side, which can fit with the outside of the piston 4, further strengthening the connection between the piston 4 and the brush roller body 1.

[0034] Then turn on the motor 19 connected to the right end of the brush roller body 1, so that the brush roller body 1 will rotate. Since the inside of the brush roller body 1 is hollow and multiple oil outlet holes are provided, the clean water can be thrown out through the rotation of the brush roller body 1, which can clean the inside of the brush roller body 1 and the brush roller sleeve 3 provided on the outside of the brush roller body 1.

[0035] like Figure 1 , Figure 4 and Figure 5 As shown, before cleaning with the brush roller body 1, the protective cover 14 can be engaged with the fixing block 15 installed inside the support frame 2 from the front and rear sides. Then, the connecting rod 16 installed on the front side of the protective cover 14 can be rotated so that its rear side fits against the upper rear side of the protective cover 14. Then, the bolt 17 is inserted into the inside of the connecting rod 16 and tightened with the upper rear side of the protective cover 14. This makes the two protective covers 14 firmly installed on the outside of the brush roller body 1. That is, when the brush roller body 1 rotates, the protective cover 14 can control the range of water splashed by the brush roller body 1, which can prevent water from splashing. At the same time, the water splashed out by the brush roller body 1 can enter the water collection tank 18 through the slope below the protective cover 14 for unified collection.

[0036] like Figure 4 and Figure 5As shown, friction frames 8 are provided on the front and rear sides inside the protective cover 14. The friction frames 8 are located on the outside of the brush roller sleeve 3. When the brush roller sleeve 3 rotates, it will rub against the friction frames 8, which can enhance the cleaning of the brush roller sleeve 3. A connecting frame 9 is fixedly installed on the outside of the friction frames 8. The connecting frame 9 is located inside the fixed limiting plate 10 and the movable limiting plate 11. Since the fixed limiting plate 10 and the movable limiting plate 11 are engaged and connected, and the inner side of the fixed limiting plate 10 is fixedly connected to the protective cover 14, a spring 12 is installed above the movable limiting plate 11. The fixed frame 13 is connected above the spring 12 for support. Since the spring 12 has elasticity, it can pull the movable limiting plate 11 upward, which can cause the fixed limiting plate 10 and the movable limiting plate 11 to separate, so that the friction frame 8 and the connecting frame 9 can be disassembled, making it convenient to replace the friction frame 8.
