Description

电动订书机的卡钉处理机构及电动订书机
本申请要求于2020年8月24日提交至中国国家知识产权局、申请号为202010858297.0、发明名称为“电动订书机的卡钉处理机构及电动订书机”的专利申请的优先权。
技术领域
本发明涉及一种电动订书机，特别涉及其卡钉处理机构。
背景技术
现有电动订书机，如中国专利文献CN2369864Y公开的一种电子控制订书机，其包括机座、马达、齿轮变速机构、偏心轮装置、杠杆机构、刀片组件、钉道组件、控制器，其在机座进纸处装有微动开关，微动开关通过控制器控制带动马达转动，马达与齿轮变速机构连接，齿轮变速机构带动偏心轮装置，偏心轮装置上带动刀片组件作上下运动，将钉道组件中的订书钉压出。装订时，需装订的文件触动一次微动开关，马达旋转一次，完成一次装钉过程。也就是说，现有的电动订书机一般包括机座、驱动器(马达)、传动机构(齿轮变速机构、偏心轮装置、杠杆机构)、刀片组件、弹出式钉道组件、控制器，通过控制器控制马达启动，通过传动机构将马达的转动方向改变成刀片组件的上下移动，然后由刀片组件将钉道组件中的订书钉压出，完成装订。当用钉子需要装钉时，能够操作弹出式钉道组件而弹出内钉道，从而方便安装订书订。
由于电动订书机易出现卡钉情况，用户在自己排除卡钉时，钉道因卡死而难以拔出。如果强行拔出易导致上刀片变形，甚至使装订机构完全破坏，电动订书机无法使用。因此，需要对此进行改进。
发明内容
本发明所要解决的技术问题是克服现有技术的上述不足而提供一种电动订书机的卡钉处理机构，使其能方便解决卡钉问题。
本发明还提供了一种电动订书机，使其能方便解决卡钉问题。

更好地，所述弹出机构包括侧轮、杠杆、压销，侧轮固定在传动机构的传动齿轮上，杠杆中部可旋转地固定在机座上，其一端由侧轮驱动，另一端与压销连接，压销由机座二侧的引导槽引导并设置在钉道组件的按键锁组件上，侧轮按装钉方向转动时，驱动杠杆一端向下而使另一端上行离开压销；侧轮按装钉反方向转动时，驱动杠杆一端向上而使另一端下压压销，压销下行使钉道组件的按键锁组件解锁而弹出钉道组件的钉道。
更具体地，所述侧轮上的圆周上设置一段凸轮，侧轮按装钉方向转动时，凸轮驱动杠杆一端向下而使另一端下行离开压销；侧轮按装钉反方向转动时，凸轮驱动杠杆一端向上而使另一端下压压销，压销下行使钉道组件的按键锁组件解锁而弹出钉道组件的钉道。
更好地，所述凸轮外侧设置一圆盘，圆盘限位杠杆一端，这样能够防止杠杆脱离凸轮。
更好地，所述杠杆与机座之间设置回复机构，杠杆失去外力时，回复机构使杠杆能够回复至原始位置。
更具体地，所述回复机构为拉簧，拉簧一端连接在机座上，另一端连接在杠杆一端上，这样可以在杠杆失去驱动力时将远离的杠杆复位。
更好地，所述弹出式钉道组件包括内钉道、外钉道、长销推、推钉器、推钉器弹簧、按键锁组件，内钉道置于外钉道内并可在外钉道内滑动，内钉道的尾部设置钩槽，长销推一端固定在外钉道尾部，另一端固定在外钉道前部，推钉器弹簧套在长销推上，其一端由外钉道尾部限位，另一端固定在推钉器上，推钉器置于内钉道中并可在内钉道内滑动，订书钉置于内钉道头部与推钉器前端之间，使钉道组件装钉与卡钉处理机构一致；所述按键锁组件包括按钮、按钮锁弹簧、固定销，按钮一端设置按压部，另一端设置钩部，钉道组件内钉道的尾部设置与钩部相应的钩槽，所述钩部平常状态时钩住钩槽，所述按钮锁弹簧一端由按钮内侧限位，另一端由钉道尾端限位。
还提供一种电动订书机，其包括上述卡钉处理机构。
本发明与现有技术相比，具有以下优点：由于在现有电动订书机上设置弹出机构，在卡钉时，使其能够利用现有电动订书机的机构，通过驱动机构反向启动并通过弹出机构，使钉道组件中的钉道弹出，从而能够使卡在钉道组件内的钉顺利取出，方便地解决了卡钉问题。

所述侧轮5的圆周上设置一段凸轮51，中间为固定部，通过固定部固定在传动机构上，本实施例中，所述传动机构4包括一组齿轮，其中一个传动齿轮41的中心设置连接槽411，与侧轮中心轴52配合，侧轮中心轴52插入连接槽411中，使传动齿轮41与侧轮5二者结合在一起，这样能够由传动机构驱动而正反同步旋转。
所述杠杆6中部通过销66可旋转地固定在机座2上，其前端61由侧轮5的驱动凸轮51驱动，后端62连接在压销65上方。
所述压销65由机座二侧的引导槽21引导并设置在钉道组件的按键锁组件80上。
所述控制器控制驱动机构按装钉方向转动时，侧轮5按装钉方向转动，驱动杠杆6的前端61向下而使后端62上行离开压销65，整个弹出机构不使按键锁组件80动作，从而也不使整个钉道组件8动作；所述控制器控制驱动机构按装钉反方向转动时，侧轮5按装钉反方向转动，驱动杠杆6的前端61向上而使后端62下压压销65，压销65下行使钉道组件8的按键锁组件80解锁而弹出钉道。
所述凸轮51外侧还设置一圆盘53，圆盘53限位杠杆6的前端61，这样能够防止杠杆6脱离凸轮51。
还设置拉簧7，拉簧一端71连接在机座2上，拉簧另一端72连接在杠杆6的前端61上，这样可以在杠杆6失去驱动力时将远离的杠杆6的前端61复位。本实施例的杠杆6的前端61为树衩状，拉簧另一端72连接在衩枝63上，这样方便连接。
所述机座2对应拉簧7中部位置处设置柱74，使拉簧7受杠杆6的前端61上行时能以柱74为支点移动，不会使拉簧7乱弹。
如图10至图14所示，所述钉道组件8包括内钉道81、外钉道82、长销推83、推钉器84、推钉器弹簧85、按键锁组件80，内钉道81置于外钉道内并可在外钉道内滑动，内钉道81的尾部设置钩槽811，长销推83一端固定在外钉道尾部，另一端固定在外钉道前部，推钉器弹簧85套在长销推83上，其一端由外钉道82尾部限位，另一端固定在推钉器84上，推钉器84置于内钉道中并可在内钉道内滑动，订书钉置于内钉道头部与推钉器84前端之间。
所述钉道组件8通过外钉道82固定在机座的底座1上，并与刀片组件配合，由刀片组件中的刀片将装于内钉道81中的订书钉推出并装订。
所述内钉道81另一端还设置钉道把手816，可以通过钉道把手816移动内钉道81。
所述按键锁组件80包括按钮86、按钮锁弹簧87、固定销88，按钮86一端设置按压部861，另一端设置钩部862，所述钩部862平常状态时钩住内钉道81的尾部钩槽811，所述按钮锁弹簧87一端由按钮86内侧限位，另一端由钉道尾端821限位。
上述按钮86的按压部861上设置压销65，按压部861受压销65向下力时，按钮86克服弹簧力而向外旋转，从而使按钮钩部862脱开内钉道81的尾部钩槽811。
如图9和图10所示，还包括与按压部861连接的止挡部863。通过设置止挡部863可以将压销65限制在按压部861上，从而防止压销65在运动过程中脱离按压部861，这样，可以使压销65带动按压部861运动。
上述刀片组件为常用的电动订书机机构，与本发明所要解决的技术问题无关，可参考其常见结构，也可参考CN2369864Y公开的结构，在此不再展开叙述。
上述弹出机构包括凸轮51、杠杆6，凸轮51通过螺钉可旋转地固定在侧轮5圆周上，杠杆6设置在凸轮51下方，可移动地连接在底座1上，并可以在底座1上前后移动。
如图4所示，上述杠杆6后部设置推动部521，推动部521与按键锁组件80的按钮86的一端配合，杠杆6顺时针转动时，压销65使按钮86顺时针转动从而使钩部862脱离内钉道81的尾部钩槽811。
上述杠杆6与底座1之间还设置回复机构，本实施例中回复机构为：回复弹簧，回复弹簧前端由杠杆6末端限位，回复弹簧后端由底座1上的支架13限位，杠杆6上还设置引导槽21，压销65插入引导槽21中，压销65固定在底座1上(图中未画出)，这样，杠杆6受凸轮51向右移动时，可由压销65引导并压缩回复弹簧，杠杆6失去凸轮51的外力时，回复弹簧的回复力使杠杆6复位。
电动订书机正常装钉时，其与中国专利文献CN2369864Y公开的电动订书机动作类似，也可参考上述文献的描述。本发明新增的部分动作过程如下：装订时，控制器启动电机正转带动传动机构转动，侧轮5顺时针转动，其圆周上的凸轮51转动时碰到杠杆6后，带动杠杆6转动，杠杆6前端61向下后，后端62抬起，与压销65不接触，这样可以正常打钉，见图4。
当电动订书机发生卡钉需要处理卡钉时，控制器启动电机反转带动传动机构转动，侧轮5逆时针转动，其圆周上的凸轮51转动时碰到杠杆6的前端61，带动杠杆6向上转动，杠杆6前端61向上抬起，后端62则向下压下压销65，压销65带动按键锁组件80向下，而使按钮86的一端往上旋转而使该端钩部862脱离内钉道81的尾部钩槽811，使内钉道81在推钉器弹簧85的作用下弹出，因此，可以方便移出卡在装订机里面的订书钉，见图8。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
