Abstract: An automatic shredder having an upper shredder cover, a lower shredder cover, a first paper box, a second paper box, a shredder cover plate, a paper pressing plate, a paper pressing roller set, a paper pick-up roller set, a paper inlet, a cutter shaft set, a drive motor, a shell and a waste paper barrel. The automatic shredder adopts a bent paper box to change the length of to-be-shredded paper by means of the flexibility and bendability of paper and the features of paper pick-up rollers on one side, is extremely simple and economical, and changes the flat paper placement structure of existing automatic shredders.

Abstract: A paper shredder has a paper tray, a paper inlet, a shredder cover, a paper pressing plate, paper pick-up rollers, a shredder cutter shaft, a motor, a wastepaper barrel, and a paper limiter. The paper tray carries a stack of to-be-shredded paper. The paper inlet guides to-be-shredded paper. The shredder cover end is connected to the shredder body by a rotary shaft, closing or opening the shredder body. The paper pressing pl presses the stack in the paper tray. The paper pick-up rollers are on one side of the paper inlet, feeding the paper tray stack into the paper inlet. The shredder cutter shaft shreds the to-be-shredded paper. The motor drives the shredder cutter shaft to operate. The wastepaper barrel is located below the paper inlet to collect shredded paper. The paper limiter is limits one of a thickness or a length of the stack placed in the paper tray.
