Description

连环刀碎纸机及碎纸机碎纸的方法 技术领域
本发明涉及碎纸领域， 尤其涉及一种使用两条形碎纸机构切割纸张的连环 刀碎纸机和对应的碎纸方法。 背景技术
目前， 在曰常生活或工作中， 经常会有文件纸张需要销毁， 从而防止他人 获得文件上所记载的资料。 碎纸机主要是利用相对转动的碎纸刀具将纸张切割 成细纸条或者碎粒。 传统的碎纸刀具包括刀轴和成组串固在所述刀轴上的碎纸 刀片， 所述碎纸刀片包括刀身和成型于所述刀身边缘的数个刀尖， 碎纸时， 两 根刀轴同时转动， 挤压纸张， 从而利用刀轴上的碎纸刀片的刀身将纸张切割成 细纸条， 通过碎纸刀片的刀尖将细纸条切割呈碎粒。
然而， 这类碎纸刀具需要将纸张切割呈碎粒， 所述碎纸刀片必须凸设有数 个刀尖， 而刀尖的加工使得这类碎纸刀具制造时必须釆用冲压工艺或者在刀片 加工完成后铲出刀尖， 不但工艺复杂， 而且刀片和刀轴必须釆用分体式结构， 无法一体成型， 进一步增加了工序和成本， 且存在刀片和刀轴之间连接不稳固 的问题。 为此， 现有技术揭露了一种新型的碎纸机， 如专利 CN99218489.4所公 开的台式碎纸机， 该碎纸机包括一组条形碎纸刀和一组螺旋横切刀， 切纸时， 先将纸张通过条形碎纸刀切割呈细纸条， 再通过螺旋横切刀将细纸条切成碎粒 状， 然而螺旋横切刀切割细纸条时， 只能釆用横向切断的方式， 极为耗力耗时， 且进一步受到螺旋横切刀本身的局限， 使得这类碎纸机一次仅能切割少量纸张， 局限大， 碎纸效率低。
因此， 急需一种可解决上述问题的碎纸机和碎纸方法。 发明内容
本发明的目的是提供一种连环刀碎纸机， 该连环刀碎纸机不但切纸省力、 切纸效率高， 且成本低易于生产。
本发明的另一目的是提供一种碎纸机碎纸的方法， 该碎纸机碎纸的方法切 纸省力且设备要求简单。
为了实现上述目的， 本发明提供了一种连环刀碎纸机， 该连环刀碎纸机包 括机架及安装于所述机架上的第一碎纸机构、 第二碎纸机构和驱动机构， 所述 驱动机构分别与所述第一碎纸机构和第二碎纸机构相连并驱动所述第一碎纸机 构和第二碎纸机构碎纸， 所述第一碎纸机构和第二碎纸机构均为条形碎纸机构 , 所述第一碎纸机构出纸口与所述第二碎纸机构进纸口相连通， 且所述第二碎纸 机构进纸口处的送纸方向与其刀轴的轴向呈一锐角。 其中， 所述条形碎纸机构 指的是将纸张同时切割成条形的碎纸机构。 条形碎纸机构的碎纸刀具上没有刀尖， 结构简单， 易于加工， 甚至可以直接通 过一体成型的方式加工以使其碎纸刀具结构稳固； 碎纸时， 所述第一碎纸机构 将纸张同时切成若干细纸条， 由于所述第二碎纸机构进纸口处的送纸方向与其 刀轴的轴向呈一锐角， 即所述若干细纸条将会被倾斜地输入第二碎纸机构内， 此时第二碎纸机构的碎纸刀具以一锐角将所述若干细纸条沿其一侧倾斜切断以 形成碎纸粒， 这种切纸方式切纸省力， 无需过大的切纸力， 且第二碎纸机构切 割时， 可同时切割从第一碎纸机构输出的若干细纸条， 且切割动作持续无间断， 碎纸纸效率高。

参考图 7至图 12, 公开了本发明所述连环刀碎纸机之第二实施例， 与第一 实施例不同的是， 所述连环刀碎纸机 100， 中， 所述第二碎纸机构 13的刀轴 61 相对于所述第一碎纸机构 14的刀轴 61倾斜设置， 且所述第一碎纸机构 13的出 纸方向（如图 10箭头 HI所示）与第二碎纸机构 14进纸口处的送纸方向（如图 10箭头 H2所示）同向，以使所述第二碎纸机构 14的碎纸方向（如图 10箭头 H， 所示）与其进纸口处的送纸方向（如图 10箭头 H2所示）呈一锐角 δ。 碎纸时， 纸张进入第一碎纸机构 13 内， 第一碎纸机构 13将纸张切割成若干细纸条， 所 述若干细纸条从第一碎纸机构 13的出纸口沿箭头 HI输出， 并沿箭头 H2输送 至相对于第一碎纸机构 14倾斜设置的第二碎纸机构 14内， 使得所述若干细纸 条以一锐角 δ倾斜地进入第二碎纸机构 14的进纸口， 所述第二碎纸机构 14沿 其碎纸方向（如图 10箭头 Η，所示）将所述若干细纸条沿其一侧同时且倾斜地切 割成碎纸粒。 其中， 为了方便细纸条进入第二碎纸机构 14内， 所述第二碎纸机 构 14的进纸口与所述第一碎纸机构 13的出纸口相对， 此时第二碎纸机构 14进 纸口处的送纸方向不变（如图 10箭头 Η2所示， 与第一碎纸机构 13的出纸方向 同向）， 当然所述第二碎纸机构 14 的进纸口也可以位于所述第一碎纸机构的出 纸口下方。
较佳者， 参考图 9和图 12, 所述连环刀碎纸机 100，还包括导纸机构 12，， 所 述导纸机构 12，包括第一导纸板 22，和第二导纸板 23，， 所述第一导纸板 22，与所 述第二导纸板 23，相对设置并在两者之间形成所述导纸通道 2Γ , 所述导纸通道 21，包括位于第一碎纸机构 13之碎纸通道内的第一导纸段 211，和位于第二碎纸 机构 14之碎纸通道内的第二导纸段 212，， 且该实施例中所述第一导纸段 211， 导纸方向 （如图 10箭头 HI 所示）与所述第二导纸段 212，导纸方向 （如图 10 箭头 H2所示）相同， 以使所述第二碎纸机构 14碎纸方向 （如图 10箭头 H，所 示）与所述第二导纸段 212，导纸方向 （如图 10箭头 H2所示）呈一锐角 5。
具体地， 参考图 9和图 12, 所述第一导纸板 22，包括位于第一碎纸机构 13 之碎纸通道内的第一离纸部 221，、位于第二碎纸机构 14之碎纸通道内的第二离 纸部 222，和连接所述第一离纸部 221，和第二离纸部 222，的连接部 223，， 所述第 二导纸板 23，同样包括位于第一碎纸机构 13之碎纸通道内的第一离纸部 23 Γ、 位于第二碎纸机构 14之碎纸通道内的第二离纸部 232，和连接部 233，，所述第一 导纸板 22，之第一离纸部 221，与所述第二导纸板 23，之第一离纸部 231，位置相对 且形成所述第一导纸段 21 Γ ,且所述第一导纸板 22，之第二离纸部 222，与所述第 二导纸板 23，之第二离纸部 232，位置相对且形成所述第二导纸段 212，，所述第一 离纸部 221，、 23 Γ包括与所述第一碎纸机构 13之刀片 62相配合的避空槽和伸入 所述第一碎纸机构 13之刀片 62间隙的导条 20Γ , 所述第二离纸部 222，、 232' 包括与所述第二碎纸机构 14之刀片 62相配合的避空槽和伸入所述第二碎纸机 构 14之刀片 62间隙的导条 201，。
本发明还公开了一种碎纸机碎纸的方法， 在所述碎纸机碎纸的方法之第一 实施例中， 该碎纸机碎纸的方法包括以下步骤： 包括以下步骤： ( S1 )将纸张 送入第一条形碎纸机构中， 所述第一条形碎纸机构将纸张同时切割成若干细纸 条； （S2 )将所述若干细纸条以一定夹角倾斜送入第二条形碎纸机构中， 所述第 二条形碎纸机构将所述若干细纸条沿其一侧切断成碎纸粒。 与现有技术相比， 本发明釆用两组条形碎纸机构分两次碎纸， 操作方便， 成本低； 第二次切纸时， 将被第一条形碎纸机构切割成的若干细纸条以一定夹角倾斜送入第二条形碎纸 机构， 使得第二条形碎纸机构将所述若干细纸条沿其一侧切断成碎纸粒， 切割 省力。
所述步骤（S2 )具体为： 将所述若干细纸条以一锐角度倾斜送入第二条形 碎纸机构中， 所述第二条形碎纸机构将所述若干细纸条切断成碎纸粒。
具体地， 所述第一条形碎纸机构和第二条形碎纸机构的刀轴平行， 将所述 若干细纸条以一锐角度倾斜送入所述第二条形碎纸机构中的具体步骤为： 将所 述若干细纸条以一锐角度变向， 将变向后的若干细纸条沿变向后的角度输入所 述第二条形碎纸机构。 该方案便于第一条形碎纸机构和第二条形碎纸机构的安 装和驱动。
不同于第一实施例， 在所述碎纸机碎纸的方法之第二实施例中， 所述第一 条形碎纸机构和第二条形碎纸机构的刀轴的轴向呈一锐角， 且所述第一条形碎 纸机构出纸口与所述第二条形碎纸机构进纸口相对， 将所述若干细纸条以一锐 角度倾斜送入所述第二条形碎纸机构中的具体步骤为： 将从所述第一条形碎纸 机构输出的若干细纸条沿所述第一条形碎纸机构的出纸方向输送至第二条形碎 纸机构内。 该方案无需将切割成的所述若干细纸条变向输送， 工序简单。
不同于第一实施例， 在所述碎纸机碎纸的方法之第三实施例中， 所述步骤
( S2 )具体为： 将所述若干细纸条垂直送入所述第二条形碎纸机构中， 所述第 二条形碎纸机构将所述若干细纸条切断成碎纸粒。
具体地， 所述第一条形碎纸机构和第二条形碎纸机构的刀轴平行， 将所述 若干细纸条垂直送入所述第二条形碎纸机构中的具体步骤为： 将从所述第一条 形碎纸机构输出的若干细纸条垂直变向， 再将变向后的若干细纸条沿所述第一 条形碎纸机构的出纸方向送入第二条形碎纸机构中。
不同于第三实施例， 在所述碎纸机碎纸的方法之第四实施例中， 所述第一 条形碎纸机构和第二条形碎纸机构的刀轴垂直， 将所述若干细纸条垂直送入所 述第二条形碎纸机构中的具体步骤为： 将从所述第一条形碎纸机构完全输出的 若干细纸条沿垂直于所述第一条形碎纸机构的出纸方向送入第二条形碎纸机构 中。
其中， 本发明还可以用于切割其他薄片类介质， 并不限定于切割纸张。 以上所揭露的仅为本发明的优选实施例而已， 当然不能以此来限定本发明 之权利范围， 因此依本发明申请专利范围所作的等同变化， 仍属本发明所涵盖 的范围。
