[0029] The piston rod of the flipping cylinder is switched to the extended state. During this process, the push rod moves forward so that its front end contacts the rear surface of the lower part of the sheet in the feed hopper and applies a forward thrust to the lower part of the sheet. The lower part of the vertical stripper plate rotates under the push of the sheet until the upper end of the sheet in the inclined state is lower than the lower end surface of the rear wall of the feed hopper. The upper end of the sheet continues to move downward under the action of its own gravity until the sheet flips to a horizontal state.

[0030] The upper parts of the end surfaces of the stripping plate 5 are rotatably connected to the left vertical plate 2 and the right vertical plate 3 by a first pin 8, and the lower parts of the end surfaces of the two ends of the stripping plate 5 are respectively provided with a second pin 9.

At the same time, the rear side surface of the material diverter plate placed in a vertical state is flush with the inner side surface of the rear side wall of the feed hopper.

[0038] When in use, the sheet is loosened above the feed hopper, and the sheet falls into the feed hopper under its own gravity until the lower surface of the sheet contacts the upper surface of the flipping base plate. At this time, the front surface of the sheet is in contact with the rear surface of the flipping plate;

[0039] Next, the piston rod of the flipping cylinder is switched to the extended state. During this process, the push rod moves forward so that its front end contacts the rear surface of the lower part of the sheet in the feed hopper and applies a forward thrust to the lower part of the sheet. The lower part of the vertical stripper plate rotates under the push of the sheet until the upper end of the inclined sheet is lower than the lower end surface of the rear wall of the feed hopper. The upper end of the sheet continues to move downward under the action of its own gravity until the sheet flips to a horizontal state.
