Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
Shredder as shown in Fig. 1 ~ 2, comprises casing 1, casing 1 is provided with paper inlet 11, and in casing 1, the position corresponding with paper inlet is provided with paper guide, and be provided with cutting mechanism below paper guide, described in the present embodiment, cutting mechanism comprises:
First traverse shaft 3, first traverse shaft outer wall is provided with the first draw-in groove 31 of the spiral distribution for holding cutting silk thread, please refer to Fig. 3 and Fig. 4;
Second traverse shaft 4, second traverse shaft and the first traverse shaft parallel interval are arranged, and the second traverse shaft outer wall is provided with the second draw-in groove 41 of the spiral distribution for holding cutting silk thread;
Cutting silk thread 2, the second draw-in groove 41 of the second traverse shaft 4 is entered after cutting silk thread is first wrapped in the first draw-in groove 31 of the first traverse shaft, and then the first draw-in groove 31 of wraparound first traverse shaft, move into the second draw-in groove 41 of the second traverse shaft 4 again, so repeatedly, two ends of finally cutting silk thread are joined together to form cutting wire wire loop; Cutting silk thread 2 is wrapped in after outside the first traverse shaft and the second traverse shaft, and the spacing distance between adjacent cutting silk thread is 0.2 ~ 0.5mm, preferably 0.3mm; Described casing 1 inwall is provided with the lead 12 for guiding cutting silk thread to walk, cutting silk thread 2 is wrapped in after outside the first traverse shaft and the second traverse shaft, is joined together to form cutting wire wire loop after walking around lead 12 between two ends; In the present embodiment, cutting silk thread adopts diameter to be the steel wire of about 0.5mm, and Steel Wire Surface is provided with jagged lines, shown in Figure 5.
First traverse shaft 3 is connected with the actuating unit of shredder with the second traverse shaft 4, driven by actuating unit and do rotating Vortex.
In the present embodiment, when paper guide comprises two duties, do motorized roller 5,6 that reversely rotate, that be arranged in parallel.
