Description

Technical Field

[0001] The present invention relates to the technical field of steel plate roller brushes, and specifically to a convenient and detachable steel plate roller brush based on a semi-circular brush disc. Background Art

[0002] During the production and use of steel plates, it is necessary to remove rust from the surface of the steel plates. Existing roller brushes for steel plate rust removal are mostly made by sleeving and installing circular brush discs around the roller shaft of the brush roller. For the above-mentioned existing roller brushes, during use, if local bristles fall off and are severely damaged, and when it is necessary to replace the circular brush disc, the staff needs to disassemble each circular brush disc one by one. After replacing the corresponding circular brush disc, each circular brush disc is gradually installed. This kind of roller brush based on a circular brush disc is rather inconvenient when replacing the bristles. To solve the above problems, the present invention provides a convenient and detachable steel plate roller brush based on a semi-circular brush disc. Summary of the Invention

[0003] Aiming at the above-mentioned existing technical deficiencies, the purpose of the present invention is to provide a convenient and detachable steel plate roller brush based on a semi-circular brush disc, which is installed in a limit strip-shaped groove through a strip-shaped connecting seat, and the semi-circular brush disc is installed on the strip-shaped connecting seat through a connecting piece, realizing the convenient replacement of the semi-circular brush disc and solving the technical problems proposed in the background art.

[0004] To solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a convenient and detachable steel plate roller brush based on a semi-circular brush disc, including: a tubular shaft, semi-circular brush discs installed on the circumferential side of the tubular shaft, and connecting pieces connecting the tubular shaft and several of the tubular shafts; axially extending limit strip-shaped grooves are symmetrically arranged on the outer side of the tubular shaft; the two limit strip-shaped grooves are spaced 180 degrees along the circumferential direction of the outer side of the tubular shaft to accommodate the installation of two semi-circular brush discs. The connecting piece includes a strip-shaped connecting seat and insertion strips, the strip-shaped connecting seat is fitted and installed in the limit strip-shaped groove, several limit pieces are symmetrically and evenly arranged on both sides of the strip-shaped connecting seat, and adjacent two of the limit pieces form a limit card slot.
