[0002] A diamond brush roll is a physical device widely used in industry. Its structure includes a roller shaft part and a brush hair part. The diamond brush roll uses the high-speed rotating brush hair to remove dirt, rust or other impurities on the surface of an object, achieving the effects of cleaning and polishing. In the strip steel metal and coil manufacturing industries, diamond brush rolls can be used for rust removal. However, during the current process of using diamond brush rolls for rust removal, dust will fly everywhere, causing great pollution and even damaging the machine.

[0003] The Chinese invention patent with publication number CN107780372A discloses a processing method of a sweeping disk assembly of a new type of environmental protection cleaning vehicle on March 9, 2018. The characteristics are that the sweeping disk assembly includes a sweeping brush, a rotating disk, and a dust collecting cover. The sweeping brush is composed of multiple matrix-shaped brush hairs and is fixed at the lower end of the rotating disk through a connection point at the top. The dust collecting cover is arranged outside the rotating disk and the sweeping brush, and an electrostatic film is attached to the inner side; locking buckles are distributed at intervals on the rotating disk and are in one-to-one correspondence with the locking holes on the dust collecting cover. This patent uses the electrostatic film to adsorb dust and reduce the phenomenon of dust flying.

[0004] However, currently, the method using an electrostatic film has not been applied to the dust generated during the rust removal of diamond brush rolls. Summary of the Invention

[0029] The diamond brush rollers currently used in the market have bristles uniformly arranged on the roller shaft both axially and radially. For example, Figure 1 and 2 , during the rotation of the diamond brush roller, the coiled material or metal sheet is rust-removed and polished. Example 1

[0030] Refer to Figure 3 , an embodiment of the present utility model provides a diamond brush roll for removing impurities from metal coils, including a roller shaft 1 and brushes 2 distributed on the roller shaft 1. The brushes 2 are circumferentially and uniformly distributed on the roller shaft 1, and the brushes 2 include curved brushes 21. Preferably, the brushes 2 are arc-shaped, and the curved grooves face the same direction. They can be distributed clockwise along the roller shaft 1 or counterclockwise along the roller shaft 1. The force angles on the coil during clockwise and counterclockwise rotations are different, and the rust removal depths are also different. As Figure 1 , during the clockwise rotation, the bristles expand outward as the roller shaft 1 rotates, and can remove thicker rust and impurities. During the counterclockwise rotation, it can remove thinner rust and impurities, and can be selected according to the actual situation. Example 2

[0031] Since dust will appear during the rust removal process, and the flying dust enters the mechanical gaps, it will cause great impacts and mechanical failures. In order to reduce the flying of dust, the following improvements are made on the basis of Example 1:

[0032] Refer to Figure 4 , in an optional embodiment, an adsorption film 3 is coated on the brushes 2, and the ends of the brushes 2 extend out of the adsorption film 3. The adsorption principle of the adsorption film 3 is based on the electrostatic adsorption principle. During the rust removal process, charged dust is generated and flies everywhere, and it is adsorbed by the electrostatic adsorption film to reduce dust.

[0033] Refer to Figure 5 , in an optional embodiment, the adsorption film 3 includes a shaping inner layer 31 sleeved outside the brushes 2 and an adsorption outer layer 32 arranged on the shaping inner layer 31. Compared with the brushes in the prior art, the curved brushes 2 have a larger distance during circumferential distribution. The shaping inner layer 31 is made of a material with a smaller amount of deformation and has a shaping function. It can also be made of a metal material to prevent the overall movement of the brushes 2 from being too large. The adsorption outer layer 32 is mainly for adsorbing dust and reducing dust emission. Example 3

[0034] On the basis of Example 2, in order to better combine the rust removal and polishing effects, the following improvements are made:

[0035] Refer to Figure 6In an optional embodiment, the brush 2 further includes a vertical brush 22, and the vertical brush 22 is evenly distributed on the roller 1 in the circumferential direction. In a stationary state, the distance between the farthest end of the vertical brush 22 and the roller 1 is greater than the distance between the curved brush 21 and the roller 1. An adsorption film 3 is provided on the vertical brush 22; the adsorption film 3 is a Y-shaped electrostatic adsorption film, and the curved brush 21 and the vertical brush 22 extend from two corners of the adsorption film 3 respectively. The adsorption film 3 does not directly participate in the grinding and will not be worn.

[0036] Specifically, the brush 2 is arc-shaped, and the curved grooves are oriented in the same direction. When the curved brush 22 rotates, it will move radially, but the farthest distance it moves cannot exceed the outermost position of the vertical brush 22. When the curved brush 22 first removes rust, the vertical brush 22 can perform secondary rust removal or preliminary grinding, and the treatment effect is better.

[0037] See also Figure 6 In an optional embodiment, the adsorption film 3 includes a shaping inner layer 31 sleeved on the outside of the brush 2 and an adsorption outer layer 32 arranged on the shaping inner layer 31. The shaping inner layer 31 can shape the vertical and curved brushes to prevent excessive deformation during the working process, which affects the use effect. Embodiment 4

[0038] On the basis of the third embodiment, the following improvements are made for better dust collection:

[0039] See also Figure 7 In an optional embodiment, a suction pipe 4 is provided between adjacent brushes, and the suction pipe 4 has a plurality of suction holes distributed along the axial direction, and the suction pipe 4 is installed on the roller 1. The gaps distributed circumferentially between the brushes 2 are relatively large, and a suction pipe 4 is provided between the gaps, and the suction pipe is covered with suction holes to promptly suck away the dust on the adsorption film 3. The suction pipe 4 can be collected on a bearing, and the bearing sleeve is provided on the roller 1, and the suction pipe 4 can rotate with the brush 2 without causing interference. After the suction pipes 4 are collected together, they are connected to an air pump to suck away the dust. The structure at the joint can adopt a bearing, and the air pump does not have to rotate with the roller 1.

[0040] See also Figure 7 In an optional embodiment, the brush 2 is arc-shaped, and the angle formed by the brush 2 is 15-45°. Preferably, it is 35°, which is convenient for dust to fly from an angle during rust removal, and moves in the center direction of the roller 1. When the roller 1 rotates, the dust is better adsorbed to prevent it from moving in a disorderly manner and having a poor adsorption effect.

[0041] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
