Then, the short shaft 410 can be driven to rotate by the first motor 409, thereby driving the connecting plate 411 to rotate, adjusting the angle of the plate to achieve multi-angle bending. After the bending is completed, the first bracket 401 is driven by the second motor 405 to move toward the surface of the conveyor belt 3. When the lever 416 contacts the contact switch 415, the vacuum pump 414 stops sucking the vacuum on the suction cup 412, and the bent plate falls to the surface of the conveyor belt 3, completing the unloading and improving the bending efficiency.
