Description
本发明属于文具领域,特别涉及一种削笔机进笔装置,尤其适合不同表面形状和直径的铅笔自动调整夹口大小并施以夹持作用,且于切削时能将铅笔圆滑而顺畅的自动进笔,完成切削后又能将铅笔轻松退出的削笔机进笔装置。
传统削笔机,其用以夹持铅笔笔杆并送入滚削装置内之夹笔进给装置,均设在削笔机壳体之正面外侧,借由一对可弹性伸缩地平行突设在壳体内之导杆定位在壳体上。削笔时,需先将进笔装置之夹盘顺着一对导杆抗着导杆内端之复原弹簧之弹性力向前拉出,其次按压夹盘操作柄使夹盘之夹口打开后,插入铅笔直到其前端进入滚屑装置之锥形孔内,释放操作柄之外力,夹盘即缩小夹口夹紧笔杆,并由导杆之弹簧弹性复原力赋与笔杆往滚削装置进给之力量,随后,随着借手摇柄转动滚削装置以行削笔,笔杆逐渐往前递进直到完成笔尖端之切削操作。削笔后,取出铅笔时,需先按压操作柄以使夹盘张开夹口后,方能将笔取出。
此种夹送笔装置操作颇为烦琐,且常因导杆拉出不够长而需重拉一次,或过早释放操作柄以致夹盘强力撞击削笔机壳体,发出剌耳撞击声,如不小心,甚至会发生夹伤手指之意外情形,同时,夹盘之三个夹块之牙齿状夹持面容易咬伤笔杆表面,以致漆面或印刷掉落或留下齿痕。
有鉴于此,申请人曾针对传统削笔机做了适当之改良,并记录在专利公开文献中,如中国专利申请号201020647480.8,一种削笔机自动给笔装置,以及专利申请号201320265052.2,一种自排式削笔机进笔装置,所揭示之削笔机自动进出笔装置即是。
其中专利申请号为201020647480.8,公开的一种削笔机自动给笔装置,包括支架和转盘,支架两对夹轮轴承座上分别定位有转轴,转轴上依次套设有夹笔转轮和摩擦轮,两摩擦轮处在两转轴的相远端上;转盘安装在两对夹轮轴承座中央,支架和转盘中央设有供笔杆穿过的通孔,其中支架朝转盘一侧的下沉轴座中放置有一传动盘,该传动盘中心设有一供滚刀座空心笔杆导向锥孔端部插设的连接孔,传动盘端面圆周上设有两个以上凹槽,该凹槽具有倾斜底部;转盘近邻传动盘一侧端面凸设有对应的拨叉,该拨叉插入凹槽中形成联动。借助传动盘传递旋转动力,且其凹槽上的倾斜底部在正反转时,抵触转盘的力度不同,使转盘与摩擦轮间产生的摩擦力不同,产生给笔时较紧、退笔时较松的两种不同手感。
而公告号为201320265052.2,公开的一种自排式削笔机进笔装置,包括一固定在削笔机壳体内的夹轮座和转盘,夹轮座朝同一侧延伸有两对夹轮轴承,两对夹轮轴承分别定位有两带橡皮夹轮的转轴;转盘安装在两对夹轮轴承中央,并设在橡皮夹轮与夹轮座之间,转盘中心设有一供滚刀刀座空心笔杆导向锥孔端部插设的连接通孔,由滚刀刀座带动转盘转动;连接通孔、笔杆导向锥孔和削笔机壳体进笔孔处在同一轴线上,其特征是每对夹轮轴承中至少一个轴承孔为横向长孔。借助一个夹轮轴承孔的横向长槽设计,使得两橡皮夹轮间距可自动调节,可夹持不同口径的笔杆进行削笔作业。
然而上述两种削铅笔机之夹送笔装置虽然可以夹送不同口径之铅笔进行削笔作业,但是夹送笔装置仅能以相对状夹持铅笔之二侧,当夹持外表形状为三角形之铅笔时,因为三角形具有三个角且夹送笔装置迁就于夹持着力点及平衡作用,所以最多只能夹住铅笔一侧之一个角以及铅笔另一侧之一个边,使得三角形铅笔之中心位置偏离削笔机之滚削中心线,如此一来三角形铅笔切削后环周之切削表面一定不平均,也就是铅笔一边切削面较大、一边切削面较小,除了美观性不佳之外,也造成握笔姿势不正确,握笔工学不对,握笔感觉不舒适。
因此,若能夹持三角形铅笔并将其中心位置维持在削笔机之滚削中心线,如此一来三角形铅笔切削后环周之切削表面一定可以相当平均。
如何改良该些削铅笔机,使得功能更完美、理想,即成为本发明人研发的重点。
本发明的目的系在提供一种削笔机进笔装置,能对具有不同直径、不同外表形状之铅笔自动调整夹口大小而施以夹笔作用,并确保铅笔之中心位置维持在削笔机之滚削中心线,且于切削过程中能圆滑而顺畅的自动进笔及退笔。

所述传动盘环周具有数个齿槽,该转盘一侧设有数个对应该数个齿槽之凸销,该些凸销分别插入对应之齿槽内,用以该传动盘被削笔机之滚削装置带动而转动时,借由齿槽与凸销之卡止作用驱动该转盘旋转。
所述传动盘旋转使该凸销位在齿槽倾斜部时,该转盘除了朝该摩擦轮移动之外,也同时推压该传动盘;该传动盘一侧设有数个弹性片,该弹性片压接于该支座表面,用以该传动盘被该转盘推压时,该弹性片被压缩而产生弹性力,可以弹性顶推该转盘紧密地接触该摩擦轮。
所述摩擦纹为辐射状。
所述定位架具有数个枢接孔,而该定位轴可借由弹性勾穿设并卡掣于该枢接孔,用以该定位轴可不脱落地于该定位架上转动。

所述定位架具有数个L形突出状之限制板,用以止挡该摩擦轮于该转轴上过多之轴向移动,且使该定位轴相对向外转动一角度时,借该摩擦轮之表面被该限制板止挡达到角度定位。

本发明具有构思巧妙、设计合理、操作简单、适应性广的特点;既能满足不同直径笔杆的切削,也能兼容诸如六角形和三角形等不同外表笔杆的切削,且可自动调整夹口大小并施以夹持力,并确保铅笔中心位置维持在削笔机滚削中心线,也即保证笔芯居中的切削,以及切削过程的自动进退功能。

所述支座10设于削笔机进笔口之壳体上(壳体为习用,因此未示出),该支座10一侧具有一传动盘40、一转盘50,该传动盘40可被削笔机之滚削装置91带动而转动,并连动该转盘50,该传动盘40和转盘50分别具有可供铅笔穿设,并连通该进笔口之连接孔41、通孔51,该转盘50表面具有数摩擦纹52。
所述定位架20结合于该支座10,该定位架20活动枢接有数个面向该转盘50的定位轴21。
所述转轴30设于定位轴21上,也即每一定位轴21上对应设置有一转轴30;每一根转轴30具有一夹笔滚轮31、一摩擦轮32,其中该夹笔滚轮31呈现围绕该转盘50之通孔51状态,用以朝向该通孔51滚转以夹送推进铅笔,该摩擦轮32可被该转盘50之摩擦传动能所带动,进而使该定位轴21、该转轴30、该夹笔滚轮31转动。
进一步,传动盘40环周具有数个齿槽42,转盘50一侧设有数个对应该数个齿槽42之凸销53,该些凸销53分别插入对应之齿槽42内,用以该传动盘40被削笔机之滚削装置91带动而转动时,借由齿槽42与凸销53之卡止作用驱动该转盘50旋转。
进一步,传动盘40旋转使该凸销53位在齿槽42倾斜部时,该转盘50除了朝该摩擦轮32移动之外,也同时推压该传动盘40;该传动盘40一侧设有数个弹性片43,该弹性片43压接于该支座10表面,用以该传动盘40被该转盘50推压时,该弹性片43被压缩而产生弹性力,可以弹性顶推该转盘50紧密地接触该摩擦轮32。
进一步,该摩擦纹52为辐射状。
进一步,该定位架20具有数个枢接孔22,而该定位轴21可借由弹性勾穿设并卡掣于该枢接孔22,用以该定位轴21可不脱落地于该定位架20上转动。
进一步,该定位架20具有数个结合部23,该结合部23可借由弹性勾而对应状地卡掣结合于该支座10所设之结合孔11。
进一步,该定位轴21设有一定位板211,该定位板211具有截断侧面,该定位板211一侧设一用以设置该转轴30之轴承座212,而该定位架20具有一突缘24,用以使该定位轴21相对向内转动一角度时,该定位板211之截断侧面被该突缘24止挡达到角度定位,避免该转轴30相对向内转动角度过大(即进笔时)。
进一步,该定位架20具有数个L形突出状之限制板25,用以止挡该摩擦轮32于该转轴30上过多之轴向移动,且使该定位轴21相对向外转动一角度时,借该摩擦轮32之表面被该限制板25止挡达到角度定位,避免该转轴30相对向外转动角度过大(即退笔时)。
进一步,该摩擦轮32系设于一套体33上,该套体33再设于该转轴30上,该套体33与于该转轴30之间可设有凸键、键槽之配合构造,借该凸键与键槽之嵌合,使套体33可带动该转轴30转动,也可沿转轴30轴向移动,该转轴30设有一止挡体34,用以止挡该套体33、该摩擦轮32于该转轴30上过多之轴向移动。
综上所述,定位架20上优选设置有三个枢接孔22和三个限制板25,且处于同圆心圆周的三等分位置;每个枢接孔22中活动定位一定位轴21,每一定位轴21上活动定位一转轴30,摩擦轮32跟随转轴旋转能抵触在对应的限制板25上,以满足三角、六角和圆形笔杆的夹持之需。
上述为本发明之各部构件及其组成方式介绍,接着再将本发明之使用实施例、特点、效益介绍如下:
请参阅图1、图6、图7A、图7B、图7C,本发明对于三角形笔杆铅笔80进行夹笔、进笔之使用例:
当铅笔80经由穿设定位架20插入转盘50之通孔51后,当摇动摇柄92使滚削装置91旋转后,传动盘40即被中空转轴93驱动,并借由齿槽42与凸销53之卡止作用驱动转盘50旋转,转盘50会使摩擦轮32转动,同时并一并使转轴30、夹笔滚轮31相对应向内旋转,因为摩擦轮32转动时会朝转轴30轴向产生一个推力,使得定位轴21转动,连带使得转轴30、夹笔滚轮31相对应向内移动形成可调适之夹口,而施以铅笔80自动夹笔作用,夹笔滚轮31也可自动调整、确保铅笔80之中心位置维持在削笔机之滚削中心线,使铅笔80切削后环周之切削表面平均、美观,让用户握笔姿势正确,符合握笔工学,舒适握笔感觉。
当夹笔滚轮31施以铅笔80自动夹笔作用后,持续相对应向内旋转时,可将铅笔80往滚削装置91之切削锥孔深处夹送推进构成圆滑而顺畅之进笔动作并进行切削。
当铅笔80切削完成时,逆向摇动摇柄92,传动盘40即带动转盘50反转,该些摩擦轮32、夹笔滚轮31即相对应向外反向旋转,同时,使得定位轴21反向转动,使得转轴30、夹笔滚轮31相对应向外移动,而不再施以铅笔80夹笔、进笔作用,铅笔80即能轻松、顺利退出。
请参阅图8A、图8B、图8C,本发明对于圆形笔杆铅笔80进行夹笔、进笔之使用例,其作动原理、使用方式及具有之功能与三角形笔杆铅笔80之使用例相同,兹不再赘述。
综合以上所述,借由该摩擦轮、该定位轴之转动使该夹笔滚轮形成可调适之夹口,能对具有不同直径、不同外表形状(如三角形、六角形、圆形等)之铅笔自动调整夹口大小而施以夹笔作用,并确保铅笔之中心位置维持在削笔机之滚削中心线,使铅笔切削后环周之切削表面平均、美观,且于切削时能将铅笔圆滑而顺畅的自动进笔,完成切削后又能将铅笔轻松退出。
以上为本案所举之实施例,仅为便于说明而设,当不能以此限制本案之意义,即大凡依所列申请专利范围所为之各种变换设计,均应包含在本案之专利范围中。
