Description

卷笔刀切削刀片 技术领域
本发明涉及一种文具, 特别的涉及一种卷笔刀切削刀片。
背景技术
市面上, 常用的卷笔刀切削刀片上是在同一个刀片、 同一个切削刃上只有一 个刃角, 在削铅笔时, 铅笔插入卷笔刀锥形导槽内, 随着切削的进行, 铅笔深入 锥形导槽, 铅笔笔芯也逐渐露出, 当铅笔旋转进入锥形导槽后部时, 铅笔笔芯处 于后导槽内, 由于切削刃角度与在切削铅笔外部木材的切削刃角度一致, 而铅笔 笔芯和笔杆木材两种材料的硬度是不一致的,这就造成卷笔刀在切削笔芯时由于 切削刃角度不合理, 而导致笔芯切削时吃刀量过大, 甚至出现笔芯被削断现象的 发生, 造成材料和时间的浪费。
发明内容
本发明的目的是提供一种在同一刀片、 同一直线的刀刃上有不同的切削刃 角, 该卷笔刀切削刀片不仅构思新颖, 结构简单, 而且削铅笔时笔芯不易断, 且 削出的笔芯效果好。
本发明的技术方案是这样实现的: 包括刀片体, 其特征在于: 所述刀片体设 有位于前部的笔杆切削部和位于后部的笔芯切削部,所述笔杆切削部的刀刃与笔 芯切削部的刀刃位于同一直线上, 所述笔芯切削部的刃角大于笔杆切削部的刃 角。
本发明的优点是:当铅笔旋转到导槽后部时,笔芯跟与较大刃角的刀刃接触, 由于此时笔芯所接触的刀刃切削刃角度大, 不会因为进刀量太大, 而出现笔芯受 力过大, 导致笔芯被削断, 并且削出的笔芯光滑、 效果好。
附图说明
图 1为本发明构造示意图。
图 2为本发明实施例装配示意图。
图 3为常用卷笔刀削铅笔时刀刃与笔芯接触状态示意图。
图 4为本发明的刀刃与笔芯接触状态示意图。
图 3, 图 4中的箭头为笔芯旋转方向。 具体实施方式
下面结合附图和具体实施例对本发明做进一步阐述:
一种卷笔刀切削刀片, 包括刀片体 1, 其特征在于: 所述刀片体 1设有位于 前部 10的笔杆切削部 3和位于后部 11的笔芯切削部 4, 所述笔杆切削部 3的刀 刃 2与笔芯切削部 4的刀刃 5位于同一直线上, 所述笔芯切削部 4的刃角 B大 于笔杆切削部 3的刃角 A。
为了使刀片体与底座固定, 上述刀片体 1设有安装螺钉的通孔 6。
当铅笔 8插入锥形导槽 7, 旋转铅笔 8, 笔杆切削部 3的刀刃 2切削铅笔 8 外部的木材, 随着铅笔 8在锥形导槽 7内的深入, 当铅笔 8到达锥形导槽 7后部 时, 笔芯 9跟与笔芯切削部 4的刀刃 5接触, 由于此时笔芯 9所接触的刀刃 5 切削刃角度大, 不会导致笔芯切削时吃刀量过大, 致使笔芯 9被削断, 且削出的 笔芯 9光滑、 效果好。
本发明构思新颖, 结构简单, 削铅笔时笔芯不易断, 且削笔芯的光滑、 效果 好, 使用方便, 适合切削木质外壳的铅笔、 眉笔、 彩笔等, 具有较大的推广应用 价值。

Claims
