[0002] Building wall panels are commonly used materials for building walls. With the various different requirements of customers for size, position, and shape, building wall panels need to be cut appropriately. The existing production equipment used for cutting building wall panels in China is single-machine single-piece direct cutting, which has low cutting efficiency. Moreover, without pre-forming treatment, building wall panels are cut directly at the markings of the wall material using a cutting tool. This direct cutting method causes burrs or cracks in the wall material due to sudden force at the contact point between the wall material and the blade, and large defects at the cut edge, resulting in a low yield rate and increased production costs. In addition, due to single-machine single-piece cutting, it cannot meet large-scale production requirements, and the production efficiency is low, which seriously affects the benefits of the enterprise.

When the wall panels cut longitudinally by the original plate longitudinal cutting device continue to be conveyed backward through the conveyor line, the excess residue can be peeled off through the arc guide plate.
