Description

设有旋转式盖板安全结构的碎纸机 技术领域：  Shredder with rotary cover safety structure Technical Field:
本实用新型涉及碎纸机技术领域，尤其涉及设有旋转式盖板安全 结构的碎纸机。  The utility model relates to the technical field of shredders, in particular to a shredder with a safety structure of a rotary cover.
背景技术： Background technique:
目前， 碎纸机已经广泛配备于办公场所或家庭中。碎纸机能将纸 张割成很多的细小纸片， 使细小纸片呈碎状、 粒状、 段状、 沬状或条 状等， 因此， 人们常使用碎纸机粉碎重要的文件资料， 以达到保密的 目的。  Currently, shredders have been widely deployed in offices or homes. The shredder can cut the paper into a lot of small pieces of paper, so that the small pieces of paper are shredded, granulated, segmented, braided or strip-shaped. Therefore, people often use shredders to smash important documents to achieve confidentiality. the goal of.
无论是应用于办公场所还是家庭中，人们都要求碎纸机使用起来 具有足够的便利性和安全性， 并能占用较少的空间， 例如， 为了方便 就近使用和节省空间， 人们常将碎纸机放置于办公桌下方， 如此便能 直接在工作位置进行碎纸。然而， 市面上常见的碎纸机， 其碎纸口一 般设在碎纸机头的顶部， 碎纸口下方安装有碎纸刀具， 由于碎纸机的 碎纸口是向上设置的， 采用的是垂直入纸的方式， 碎纸时需要尽量垂 直放纸，这就要求在碎纸口上方要有足够的空间以供垂直放纸，因此， 在一些上方空间不足够的使用场合如办公桌下方等，常见的碎纸机便 显得不够便利， 还容易发生堵纸、 卡纸的现象， 给使用者带来诸多不 便。 而且这种碎纸机只有一种入纸的方式（垂直入纸的方式） ， 不 能满足所有使用者的需求， 应用起来不够灵活。 另外， 这种碎纸 机的碎纸口是敞开式的， 往往没有被遮盖起来， 在进行碎纸工作时， 一不注意就可能发生领带、 头发或手指（尤其小孩的手指）等被卷入 碎纸口的情况， 隐藏着很大的安全隐患。 即使生产厂家为了通过安规 认证而将碎纸口大小尽可能地缩小， 上述安全隐患仍然不可避免， 碎 纸机的安全性无法得到更大的提高，而且还给使用者带来诸如纸张 难以对准碎纸口等不便， 显得不够人性化。 Whether it is used in the workplace or in the home, people are required to use the shredder for convenience and safety, and can take up less space. For example, in order to facilitate the use and save space, people often use shredded paper. The machine is placed under the desk so that it can be shredded directly at the work location. However, in the common shredders on the market, the shredded paper is usually placed on the top of the shredder head, and the shredder cutter is installed under the shredder. Since the shredder of the shredder is set upward, the Vertical paper feeding method, paper shredding should be as vertical as possible, which requires sufficient space above the shredded paper for vertical paper feeding, so in some places where the space is not enough, such as under the desk, etc. The common shredder is not convenient enough, and it is easy to cause paper jam and paper jam, which brings a lot of inconvenience to the user. Moreover, the shredder has only one way of feeding paper (vertical paper feeding method), which cannot meet the needs of all users, and is not flexible enough to be applied. In addition, the shredder of the shredder is open and often not covered, when shredding work, If you don't pay attention, it may happen that a tie, hair or fingers (especially a child's finger) is caught in the shredded paper mouth, which hides a great safety hazard. Even if the manufacturer shrinks the size of the shredder as much as possible in order to pass the safety certification, the above safety hazards are still inevitable, the safety of the shredder cannot be improved, and the paper is difficult for the user. The inconvenience of quasi-shredded paper mouth is not human enough.

Port 6, the paper inlet 6 communicates with the paper shred 3 through the gap; the guide wheel assembly includes a first guide wheel set 41 disposed on the panel 10, and a second guide wheel set 42 disposed at the upper end of the shredded paper port 3; The panel 10 is located at the position of the paper inlet 6 and is provided with a paper feed detecting switch 9, which can be light control or machine. The cover plate 5 and the top of the shredder head 1 are provided with a self-locking device for use, and the self-locking device may be of an electric type or a mechanical type.
上述设有旋转式盖板安全结构的碎纸机的工作原理是： 使用前， 转动盖板 5， 使盖板 5放平， 由于盖板 5与碎纸机头 1的顶部设有配合使 用的自锁装置， 在放平盖板 5时自锁装置动作， 盖板 5被锁紧。 此时， 入纸口 6通过上述间隙连通碎纸口 3， 其采用的是水平入纸的方式， 即 碎纸时只需手持纸张水平放入入纸口 6，入纸检测开关 9检测到相关信 号后， 根据检测到的信号， 碎纸机的控制电路控制第一导向轮组 41、 第二导向轮组 42和碎纸刀具 7动作， 纸张便在第一导向轮组 41和第二 导向轮组 42的作用下送入碎纸口 3，再由碎纸刀具 7对纸张进行碎纸处 理， 碎纸后的细纸掉入碎纸机头 1下方的纸碎箱 11内。 当发生堵纸、 卡纸等情况，开启自锁装置，使盖板 5解除锁紧状态，然后将盖板 5 翻 起来，便可方便地对碎纸口 3位置进行清纸。当将盖板 5旋转翻起来后， 盖板 5不再遮挡碎纸口 3， 此时其可采用垂直入纸的方式， 即可直接将 纸张垂直放入碎纸口 3进行碎纸处理。  The working principle of the above-mentioned shredder with a rotating cover safety structure is: before use, the cover 5 is rotated to flatten the cover 5, since the cover 5 is matched with the top of the shredder head 1 The self-locking device operates when the cover plate 5 is laid, and the cover plate 5 is locked. At this time, the paper inlet 6 communicates with the paper shred 3 through the gap, which adopts a horizontal paper feeding mode, that is, when the paper is shredded, only the paper is horizontally placed in the paper inlet 6, and the paper detecting switch 9 detects the relevant. After the signal, based on the detected signal, the control circuit of the shredder controls the first guide wheel set 41, the second guide wheel set 42 and the shredder tool 7, and the paper is in the first guide wheel set 41 and the second guide wheel. The group 42 is fed into the shredded paper port 3, and the paper is shredded by the shredder tool 7, and the shredded paper is dropped into the paper shredder 11 below the shredder head 1. When a paper jam, paper jam, etc. occurs, the self-locking device is opened, the cover 5 is unlocked, and then the cover 5 is turned over, so that the position of the paper shred 3 can be easily cleared. When the cover 5 is rotated and turned up, the cover 5 no longer blocks the shredded paper 3, and at this time, the vertical paper feeding mode can be adopted, and the paper can be directly placed into the shredded paper port 3 for shredding.
因此，本实用新型所述的设有旋转式盖板安全结构的碎纸机既能 采用垂直入纸的方式， 也能采用水平入纸的方式， 可根据不同的使用 需求而灵活应用。 另外， 当采用水平入纸的方式时， 本实用新型所述 的设有旋转式盖板安全结构的碎纸机对上方空间的要求不高，应用在 一些特殊的使用场合如办公桌下方等仍具有很高的便利性，使用者能 轻松、方便地将纸张水平放入便能完成碎纸处理。采用水平入纸的方 式时， 盖板 5盖设在碎纸口 3的正上方位置， 能有效地防止发生领带、 头发或手指等被卷入碎纸口 3的情况， 极大地减少安全隐患， 提高碎 纸机的安全性，并能有效防止发生堵纸、卡纸的现象，设计更人性化。 Therefore, the shredder with the safety structure of the rotary cover according to the present invention can adopt the method of vertical paper feeding or horizontal paper feeding, and can be flexibly applied according to different use requirements. In addition, when the method of horizontal paper feeding is adopted, the shredder with the safety structure of the rotary cover according to the present invention has low requirements on the upper space, and is applied to some special use occasions such as under the desk. With high convenience, users can easily and conveniently put the paper horizontally to complete the shredding process. When the horizontal paper feeding method is adopted, the cover plate 5 is disposed at a position directly above the shredded paper mouth 3, which can effectively prevent the occurrence of a tie, When the hair or fingers are caught in the shredded paper mouth 3, the safety hazard is greatly reduced, the safety of the shredder is improved, and the phenomenon of paper jam and paper jam is effectively prevented, and the design is more humanized.
进一步的， 本实施例一中， 所述面板 10的上表面从入纸口 6至碎 纸口 3方向向下倾斜， 如此可有利于纸张顺利地进入碎纸口 3。  Further, in the first embodiment, the upper surface of the panel 10 is inclined downward from the paper inlet 6 to the paper shred 3, so that the paper can smoothly enter the shredder port 3.
进一步的， 本实施例一中， 所述前挡板 2为透明板或半透明板， 所述盖板 5为透明板或半透明板， 当然前挡板 2和盖板 5也可以为非透 明板。如果前挡板 2和盖板 5采用透明或半透明材料制成， 能有助于观 察入纸、 堵纸、 卡纸等情况， 更具便利性。  Further, in the first embodiment, the front baffle 2 is a transparent plate or a translucent plate, and the cover plate 5 is a transparent plate or a translucent plate. Of course, the front baffle 2 and the cover plate 5 may also be non-transparent. board. If the front bezel 2 and the cover 5 are made of a transparent or translucent material, it can be helpful for observing paper, paper jam, paper jam, etc., and is more convenient.
实施例二， 如图 5所示， 与实施例一不同之处在于， 该设有旋转 式盖板安全结构的碎纸机，其盖板 5的前端转动连接于碎纸机头 1的顶 部， 同样能起到与实施例一相同的作用。  Embodiment 2, as shown in FIG. 5, is different from Embodiment 1 in that the shredder with the rotating cover safety structure has a front end of the cover plate 5 rotatably connected to the top of the shredder head 1. The same effect as in the first embodiment can be achieved as well.
以上所述仅是本实用新型的较佳实施例，故凡依本实用新型专利 申请范围所述的构造、特征及原理所做的等效变化或修饰， 均包括于 本实用新型专利申请范围内。  The above description is only a preferred embodiment of the present invention, and equivalent changes or modifications made to the structures, features, and principles described in the scope of the present patent application are included in the scope of the present patent application. .
