Description

Technical Field

[0001] The utility model relates to the technical field of overlapping roof board processing equipment, in particular to an overlapping roof board cutting device. Background Art

[0002] Color-coated steel composite panels are suitable for roofing industrial and residential buildings, warehouses, specialty structures, and large-span steel structures. They are lightweight, high-strength, richly colored, easy and quick to install, earthquake-resistant, fireproof, rainproof, long-lasting, and maintenance-free, making them widely adopted. To facilitate tile installation, lap-jointed roof panels typically feature an extension connecting section extending outward from one side of the tile. The upper lap-jointed roof panel is joined to the lower lap-jointed roof panel via the extension connecting section. The extension covering the lower lap-jointed roof panel also prevents rainwater from seeping into the gaps between the tiles. Due to its unique structure, after the lap-jointed roof panel is assembled, it must be cut not only in its entirety but also from a section of the upper panel to remove the composite core, leaving only the composite tile panel as the extension connecting section. Currently, lap-jointed roof panels are often cut using band saws, which are unable to perform partial cuts, necessitating manual labor for subsequent cutting, which somewhat impacts the efficiency of lap-jointed roof panel processing.
