[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 2 , a steel strip cleaning machine disclosed in an embodiment of the utility model includes a cleaning box 1, which is a rectangular box-shaped body. A cleaning roller 2 and an idler roller 3 are rotatably installed in the cleaning box 1. Brush bristles are provided on the surface of the cleaning roller 2. The axis of the idler roller 3 and the axis of the cleaning roller 2 are located in the same plane perpendicular to the ground. A driving motor 4 is fixedly connected to the outside of the cleaning box 1. The cleaning roller 2 is connected to the output end of the driving motor 4. The rotation direction of the driving motor 4 is opposite to the feeding direction of the steel strip. Two cleaning rollers 2 are provided, and the two cleaning rollers 2 are distributed at both ends of the cleaning box 1. Two idlers 3 are correspondingly provided. The two idlers 3 are respectively arranged in different directions of the cleaning roller 2, and the junction positions of the two idlers 3 and the cleaning roller 2 are at different heights.

[0032] Specifically, a cleaning roller 2 and an idler 3 are set in the cleaning box 1, so that the steel strip passes between the cleaning roller 2 and the idler 3, and the intersection positions of the two idlers 3 and the cleaning roller 2 are set at different heights. When the steel strip passes through multiple cleaning boxes 1 for cleaning, it is wavy with the idler 3 as the fulcrum.

[0033] In this way, the steel strip is supported by the roller 3, and the junction positions of the two rollers 3 and the cleaning roller 2 are set at different heights, so that the steel strip is bent at the position point of the roller 3. On the one hand, the contact area with the roller 3 is increased, and on the other hand, the pressure between the steel strip and the roller 3 is increased, thereby reducing the jumping of the steel strip during the cleaning process, so that the cleaning roller 2 maintains appropriate pressure on the surface of the steel strip, thereby maintaining a better cleaning effect.

[0034] In some feasible embodiments, the cleaning box 1 is in the shape of a rectangular box, and a drain port is provided at the bottom of the cleaning box 1. Two cleaning rollers 2 and supporting rollers 3 are respectively arranged at the two ends of the cleaning box 1, wherein the cleaning roller 2 at one end is located on the upper side of the supporting roller 3, and the cleaning roller 2 at the other end is located on the lower side of the supporting roller 3, so that the two cleaning rollers 2 clean the two sides of the steel strip respectively. The cleaning roller 2 is connected to the drive motor, and the rotation direction of the drive motor 4 is opposite to the feeding direction of the steel strip to increase the cleaning effect. The junction positions of the two supporting rollers 3 and the cleaning roller 2 are at different heights. Even if the steel strip is inclined between the two supporting rollers 3, the steel strip is supported by the supporting roller 3.

[0035] During use, the cleaning box 1 is provided with multiple devices, and is also provided with a spraying device for detergent, a traction device for the steel belt, and a drying device, which are all existing technologies and will not be repeated here.

[0036] As a specific embodiment of a steel strip cleaning machine provided in the application, a U-shaped frame 21 is slidably installed in the cleaning box 1, and the cleaning roller 2 is installed on the U-shaped frame 21. The U-shaped frame 21 is connected to a lifting drive 22, and a flexible connector 23 is provided between the cleaning roller 2 and the output end of the drive motor 4.

[0037] In general, by installing the cleaning roller 2 on a sliding U-shaped frame 21 and setting a lifting drive 22, it is convenient to adjust the distance between the cleaning roller 2 and the supporting roller 3 during use, so that the cleaning roller 2 maintains appropriate pressure on steel belts of different thicknesses. At the same time, when the cleaning roller 2 is worn, the cleaning roller 2 maintains appropriate pressure by adjusting the distance between the cleaning roller 2 and the supporting roller 3, thereby increasing the service life of the cleaning roller 2.

[0038] In some feasible embodiments, the flexible connector 23 can be configured as a flexible shaft connection. The flexible shaft should be configured with a certain margin.

By setting up a return water tank 11, the liquid that may seep out of this position is collected.

[0047] As another specific embodiment of the steel strip cleaning machine provided in the application, both ends of the upper roller 3 are slidably mounted on the side wall of the cleaning box 1, and both ends of the roller 3 are provided with a spacing adjustment member 31.

[0048] In combination with specific usage scenarios, by setting an adjustable roller 3 and cooperating with an adjustable cleaning roller 2, the offset distance between the two cleaning rollers 2 and the roller 3 can be changed, and the wave amplitude of the steel strip can be adjusted according to the different thicknesses of the steel strip.

[0049] Further, see Figure 4The spacing adjustment member 31 includes a sliding groove 311 arranged on the side wall of the cleaning box 1, and a slider 312 is slidably installed in the sliding groove 311. A slider 312 is provided at both ends of the roller 3, and the slider 312 is installed with an adjusting rod 313, and the adjusting rod 313 is connected to a driving member 314.

[0050] It should be understood that by providing the spacing adjustment member 31 , the roller 3 can be partially adjusted automatically, which is convenient for use.

[0051] In some feasible embodiments, the sliding groove 311 is opened on the side wall of the cleaning box 1, the slider 312 is a rectangular block, the adjusting rod 313 is a threaded rod, the driving member 314 is a motor, and the side wall of the cleaning box 1 is rotatably provided with a gear connected to the driving member 314, and the adjusting rod 313 is threadedly connected to the gear.

[0052] In some feasible embodiments, for ease of setting, the roller 3 located above the cleaning roller 2 is set to be adjustable, and the central axis of the roller 3 passes through the U-shaped frame 21. Rectangular holes are set on both sides of the U-shaped frame 21 to adapt to the height change of the roller 3.
