The pistons in the two cylinders are squeezed by the pressure of the air to squeeze the piston rods to move, and the first piston rod 303 moves to the right, thereby driving the L-shaped sliding plate 301 to slide to the right. At the same time, the second piston rod 309 drives the connecting plate 2 to move upward. That is, at this time, the discharge plate 1 slides to the right along with the L-shaped sliding plate 301 while moving upward, increasing the inclination angle of the discharge plate 1 to facilitate the sliding of waste. Then the solenoid valves of the first air outlet pipe 305 and the second air outlet pipe 308 are opened, and the solenoid valves of the first air inlet pipe 304 and the second air inlet pipe 307 are closed.

[0017] In the present invention, preferably, the discharge plate 1 is provided with a baffle 101 to ensure that the waste can slide smoothly along the discharge plate 1 to the waste collection box to avoid falling in the middle.

[0018] The working principle of the utility model is as follows: during the stamping process of the workpiece, the waste material falls from the lower die onto the discharge plate 1, the electromagnetic valves of the first air inlet pipe 304 and the second air inlet pipe 307 are opened to start injecting gas into the first cylinder and the second cylinder 306, the pistons in the two cylinders are squeezed by the pressure of the air to squeeze the piston rod to move, the first piston rod 303 moves to the right, and then drives the L-shaped sliding plate 301 to slide to the right, and at the same time the second piston rod 309 drives the connecting plate 2 to move upward, that is, at this time the discharge plate 1 moves upward while also moving along with the L-shaped sliding plate The movable plate 301 slides to the right to increase the inclination angle of the discharge plate 1 to facilitate the waste to slide down, and then the solenoid valves of the first outlet pipe 305 and the second outlet pipe 308 are opened, and the solenoid valves of the first inlet pipe 304 and the second inlet pipe 307 are closed. As the gas in the two cylinders is discharged, the second piston rod 309 drives the connecting plate 2 to reset, and the first piston rod 303 drives the L-shaped sliding plate 301 to reset, and then drives the discharge plate 1 to reset. During the resetting process, the discharge plate 1 will vibrate, further accelerating the waste to slide into the waste collection box.
