blade 3; then, the cutoff arm is driven by the driving member to slide downwards, and the movable blade on the cutoff arm is driven to get close to the fixed blade, and finally cooperates with the fixed blade to cut off the truss footing. - When the truss footing is cut off, the truss continues to be transported backward to a truss shearing device, and an upper chord rib and a lower chord rib of the truss are cut off on the truss shearing device, thereby completing the cutoff of the whole truss.
- In the present application, the
movable blade 5 is driven by the cutoff arm to get close to the fixedblade 3, and then themovable blade 5 cooperates with the fixedblade 3 to cut off thetruss footing 100. Thus, the automatic cutoff of thetruss footing 100 of thetruss 10 is achieved without the manual cutoff, having a higher automation degree, improving the production efficiency, and reducing the labor intensity of the operator and the potential safety hazard.
