[0029] Combination Figure 1-Figure 3The embodiment of the present application provides a strip steel grinding head 100, which includes a connecting layer 110, an elastic layer 120, a first connecting member 130 and a grindstone 140, wherein the elastic layer 120 is elastic, and the grindstone 140 is used to contact the strip steel to grind the strip steel. The elastic layer 120 and the connecting layer 110 are arranged at intervals along the stacking direction, and one end of the first connecting member 130 is connected to the elastic layer 120, and the other end is connected to the connecting layer 110 to connect the connecting layer 110 and the elastic layer 120. The outer wall of the first connecting member 130 forms an adjustment space 193 with the elastic layer 120 and the connecting layer 110, that is, the first connecting member 130 is only in contact with and connected to a part of the elastic layer 120 and the connecting layer 110, and the part between the connecting layer 110 and the elastic layer 120 except the first connecting member 130 is the adjustment space 193. The grindstone 140 is fixedly arranged on a side of the elastic layer 120 away from the connecting layer 110, and the projection of at least part of the grindstone 140 on the elastic layer 120 overlaps with the adjustment space 193, that is, the projection of the entire grindstone 140 on the elastic layer 120 overlaps with the adjustment space 193, or the projection of part of the grindstone 140 overlaps with the first connecting member 130, and the projection of the remaining part of the grindstone 140 overlaps with the adjustment space 193.
[0030] The strip steel grinding head 100 provided in the present application has an elastic elastic layer 120, so the elastic layer 120 can be elastically deformed in the adjustment space 193. Since the grinding stone 140 is fixedly arranged on the side of the elastic layer 120 away from the connecting layer 110, and at least part of the projection of the grinding stone 140 on the elastic layer 120 overlaps with the adjustment space 193, that is, the grinding stone 140 can achieve angle change through the elastic deformation of the elastic layer 120 in the adjustment space 193. Therefore, when the angle of the strip steel changes during the process of grinding the strip steel, the angle of the grinding stone 140 can change with the change of the strip steel to better fit the strip steel, so that the texture polished on the strip steel is more uniform.
[0031] Of course, the larger the interval between the connection layer 110 and the elastic layer 120, the larger the size of the adjustment space 193, the greater the deformable amount of the elastic layer 120, and thus the greater the angle change of the grindstone 140. The interval between the connection layer 110 and the elastic layer 120 can be set according to actual conditions, and there is no limitation to this. Specifically, the angle change of the grindstone 140 is about 10°, which can meet the requirements of laminating the strip steel.
[0032] In some embodiments, the elastic layer 120 can be made of any elastic material, and in order to make the elastic layer 120 more flexible, the thickness of the elastic layer 120 needs to be set thinner. Specifically, in order to make the elastic layer 120 have a certain strength and not easy to be damaged, the elastic layer 120 can be made of steel sheet.
[0033] In some embodiments, the first connecting member 130 can be disposed in the middle of the elastic layer 120, so that the elastic layer 120 can be uniformly elastically deformed around, so that the angle of the grindstone 140 can be more flexible, like a human wrist joint, and can be tilted in any direction to better fit the strip steel. In order to ensure the strength of the first connecting member 130, the first connecting member 130 can be a block structure, and the first connecting member 130 and the connecting layer 110 and the elastic layer 120 can be connected by screws.
[0034] In some embodiments, since the elastic layer 120 is thin and has low rigidity, and it will deform repeatedly during the strip grinding process, and the grindstone 140 has a certain weight, the elastic layer 120 directly drives the grindstone 140 to change its angle, which can easily damage the elastic layer 120. Therefore, the strip grinding head 100 further includes a mounting layer 180, which is connected to the side of the elastic layer 120 away from the connecting layer 110, and the side of the mounting layer 180 away from the elastic layer 120 is provided with a mounting groove 181, and the grindstone 140 is mounted in the mounting groove 181. The mounting layer 180 may have a certain thickness, so as to have a certain strength and rigidity, so as to serve as a mounting carrier for the grindstone 140.
[0035] In some embodiments, since the mounting layer 180 has a certain thickness, if the elastic layer 120 is directly attached to the mounting layer 180, the deformation of the elastic layer 120 will be affected. Therefore, in order to further improve the flexibility of deformation of the elastic layer 120, the strip steel grinding head 100 further includes a second connecting member 182, the mounting layer 180 and the elastic layer 120 are spaced apart, and the second connecting member 182 connects the mounting layer 180 and the elastic layer 120.
[0036] A plurality of second connecting members 182 may be provided, and the plurality of second connecting members 182 are spaced apart along the circumference of the mounting layer 180 to improve the connection strength between the mounting layer 180 and the elastic layer 120. Specifically, the second connecting member 182 may be a bolt.
[0037] In some embodiments, in order to provide certain support for the elastic layer 120 and further reduce the damage of the elastic layer 120, the strip steel grinding head 100 further includes a pad 183, the pad 183 is interference-set between the elastic layer 120 and the mounting layer 180, and the second connecting member 182 is set in the support block, and the pad 183 can provide support for the elastic layer 120. In order not to affect the deformation of the elastic layer 120, the pad 183 can be made of an elastic material such as rubber.
[0038] It should be noted that in order to ensure the overall strength and rigidity of the strip grinding head 100, the connecting layer 110 and the mounting layer 180 can be made of metal materials such as steel, aluminum, etc., and the connecting layer 110 and the mounting layer 180 can be plate-shaped or block-shaped structures.
[0039] In some embodiments, a cleaning member 150 is further provided on a side of the mounting layer 180 away from the elastic layer 120 . The cleaning member 150 is disposed on a side of the grindstone 140 , and is used to wipe the strip steel.
[0040] The grinding stone 140 generates a lot of dust on the strip steel during grinding. Therefore, a cleaning member 150 is provided on the side of the mounting layer 180 away from the elastic layer 120 to wipe the strip steel after grinding. Specifically, the cleaning member 150 can be a brush or a wear-resistant sponge. One, two or more cleaning members 150 can be provided, and there is no limitation on this.
[0041] Since the cleaning member 150 is made of flexible material, it is difficult to directly connect to the mounting layer 180 , so a rigid first mounting bracket 151 may be provided. The first mounting bracket 151 may be connected to the mounting layer 180 by welding or screwing, and the cleaning member 150 is installed in the first mounting bracket 151 to achieve connection with the mounting layer 180 .
[0042] In some embodiments, in order to collect dust generated by the grinding stone 140 during the process of grinding the strip steel and reduce pollution to the environment, the strip steel grinding head 100 also includes a vacuum generator 160 and a dust box 170. The vacuum generator 160 is installed on the mounting layer 180. The vacuum generator 160 has a suction port 161 and an exhaust port 162. The suction port 161 is arranged on the side of the mounting layer 180 away from the elastic layer 120. The dust box 170 is installed on the connecting layer 110, and the exhaust port 162 is connected to the dust box 170.
[0043] That is, when the grinding stone 140 is grinding the strip steel, the vacuum generator 160 generates negative pressure, and the dust is sucked into the vacuum generator 160 through the air suction port 161, and then enters the dust box 170 through the exhaust port 162 to collect the dust. The exhaust port 162 and the dust box 170 can be connected through a hose, and the dust box 170 can be connected to the outer wall filter so that the dust is filtered and discharged into the atmosphere, reducing pollution to the environment.
[0044] The suction port 161 and the exhaust port 162 can be separately arranged at both ends of the vacuum generator 160 . The suction port 161 is arranged on the side of the installation layer 180 away from the elastic layer 120 , and the exhaust port 162 is arranged on the side close to the installation layer 180 to facilitate connection with the dust box 170 .
[0045] One, two or more vacuum generators 160 can be provided, and it can be provided according to actual conditions, and there is no limitation on this. In order to facilitate the installation of the vacuum generator 160, the strip steel grinding head 100 further includes a second mounting bracket 163, and the second mounting bracket 163 is fixedly provided on the mounting layer 180, and the vacuum generator 160 is installed in the second mounting bracket 163.
[0046] In some embodiments, in order to improve the integration of the strip steel grinding head 100 and reduce the overall space occupied by the strip steel grinding head 100, the connecting layer 110 is provided with a first avoidance hole 111, and the elastic layer 120 is provided with a second avoidance hole 121. The first avoidance hole 111 and the second avoidance hole 121 are arranged correspondingly, and the vacuum generator 160 is arranged in the first avoidance hole 111 and the second avoidance hole 121, so that the exhaust port 162 can be arranged on the side close to the installation layer 180 to facilitate the connection with the dust collection box 170.
