Moving mechanism of brush of dry brushing machine

Abstract

The invention relates to a moving mechanism of a brush of a dry brushing machine. The moving mechanism comprises a fixed bearing block, a movable bearing block, a guide track, a brush rotation motor and a brush linear moving motor, the brush is positioned above a backup roll, the guide track consists of a track and a slider mounted in the track, the slider is fixed onto the fixed bearing block, the track is fixed onto the movable bearing block, a rotating shaft of the brush is supported on the movable bearing block and is in transmission connection with an output shaft of the brush rotation motor by a retractable coupler, the movable bearing block is connected with an eccentric wheel by a connecting rod, and the eccentric wheel is mounted on an output shaft of the linear moving motor. By the aid of the moving mechanism, the brush not only can rotate, but also can linearly move along the direction of a brush shaft. The brush rotates while reciprocating axially, accordingly, capability of removing oxide scales and impurities on surfaces of strips is remarkably improved, the surface of the brush is worn uniformly due to axial reciprocation of the brush, and abrasion grinding maintenance period of the brush is prolonged.

Description

technical field [0001] The invention relates to a device for removing scale on the surface of a hot-rolled strip material, in particular to a movement mechanism for a brush of a dry brushing machine. Background technique [0002] At present, the production of copper alloy strips, especially the quality of high-precision electronic copper strips, has higher and higher requirements. Not only is there strict requirements on the follow-up processing of plates and strips, but more and more attention is paid to the processing of the initial process of materials. It is very necessary to set up the dry brushing device, and the process setting is very necessary: ​​first, to prevent the scale and impurities on the surface of the plate and strip from polluting the subsequent equipment and thus affecting the surface quality of the material after milling; second, to prevent the black during the milling process Pollution of the oxide skin to the surrounding environment. [0003] In the...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used dry brushing machine, the brush is rotated at a fixed position, and the scale and impurities are treated on the surface of the passing plate and strip, but the effect is not very satisfactory, and it brings inconvenience to the maintenance of the brush

[0004] The brush rotates at a fixed position, which can remove most of the scale and impurities, but it is not easy to remove the scale and impurities with strong adhesion

[0005] The brush rotates at a fixed position. For general strip materials, after the brush has been used for a period of time, the brush surface that is often in contact with the material will be concave due to wear and tear. It will be "convex", so the brush needs to be sharpened frequently, and the disassembly and grinding of the brush will take time and cost
