[0024] By adopting the above technical solution, when the metal sheet at the bottom end inside the storage frame 2 is pushed, the spring 37 is extended to push the buffer plate 32 at the upper end of the slide rod 34 to contact the lower end of the lower metal sheet. When the metal sheet at the bottom end leaves the storage frame 2, the metal sheet in the storage frame 2 moves downward under the action of gravity, and the metal sheet pushes the buffer plate 32 to enter the groove 33. At the same time, the slide plate 35 at the lower end of the slide rod 34 compresses the damping rod 36 and the spring 37.

By setting the buffer component 3, when the metal sheet at the lower end of the storage frame 2 is pushed, the spring 3 The buffer plate 32 at the upper end of the sliding rod 34 is elastically extended to contact the lower end of the lower metal sheet. When the lowermost metal sheet leaves the storage frame 2, the metal sheet in the storage frame 2 moves downward under the action of gravity, and the metal sheet pushes the buffer plate 32 to enter the groove 33. At the same time, the slide plate 35 at the lower end of the sliding rod 34 compresses the damping rod 36 and the spring 37. The damping rod 36 and the spring 37 can act as a buffer group for the downward movement of the metal sheet in the storage frame 2. By setting the buffer assembly 3, the metal sheet in the storage frame 2 can act as a buffer group for the downward movement, so as to prevent the metal sheet from falling directly downward and hitting the feeding table 1.
