Description

一种薄膜切边齿形刀
技术领域
本发明涉及一种切割刀具，具体涉及一种薄膜切边齿形刀。
背景技术
众所周知，越薄越软的东西越难切，将薄膜边沿切出想要的纹路更难。过去薄膜切边通常有两种形式：1）工业化使用模具切割，刀具直上直下，过薄的薄膜无法切；2）手工切纸刀，上刀与下刀一端铰接在一起，该种方式切割速度慢，不适合工业生产，并且切割过薄的薄膜时难免会留下斜口。
发明内容
本发明针对以上问题，提供了一种适用于工业化、并且切口整齐的薄膜切边齿形刀。
本发明的技术方案是：包括刀架和设在刀架上的刀具，所述刀具包括定刀和动刀，所述动刀包括转动轴和若干设在转动轴上的动刀片，所述刀架中部开设有刀具容置腔，所述刀具容置腔的一侧设有用于穿设转动轴的开孔，所述开孔中固定有轴承，所述转动轴固定在轴承的内圈上；
所述刀具容置腔的外壁上开设有用于连接定刀的固定孔，所述定刀上开设有与所述固定孔一一对应的安装孔，使得定刀可拆卸的连接所述固定孔；
所述定刀的刀刃与转动轴的轴线平行，所述动刀片的刀刃倾斜于所述定刀的刀刃。
若干所述动刀片的刀刃交替方向相反地倾斜于所述定刀的刀刃。
若干所述动刀片的刀刃与定刀的刀刃夹角为3-15°。
所述刀具容置腔开孔对面敞口设置，并在敞口上连接废料导筒。
所述安装孔为长条形。
本发明的有益效果是：在动刀转动轴上设若干与定刀倾斜的定刀，相对倾斜的刀刃切割时形成剪刀形状，更利于薄膜的切割，并且可实现连续剪切，剪切快速有效；动刀交替方向相反地倾斜于定刀，两个方向切刀相互补充切割，避免产生斜口；定刀安装孔为长条形，使得定刀相对动刀的位置可调，这样就可以保证定刀和动刀间的间距足够小，便于切割的进行。本发明结构简单，解决了薄膜切边难的问题，可切割厚度0.01mm以下的薄膜。
附图说明
图1是本发明的结构示意图，
图2是本发明的俯视图，
图3是本发明中转动轴和动刀的展开图；
图中1是刀架，2是定刀，21是安装孔，3是动刀，31的转动轴，32是动刀片，4是刀具容置腔，5是废料导筒，6是安装座。
具体实施方式
下面结合附图对本发明作具体说明。
本发明如图1-3所示，包括刀架1和设在刀架1上的刀具，所述刀具包括定刀2和动刀3，所述动刀3包括转动轴31和若干设在转动轴31上的动刀片32，所述刀架1中部开设有刀具容置腔4，所述刀具容置腔4的一侧设有用于穿设转动轴31的开孔，所述开孔中固定有轴承，所述转动轴31固定在轴承的内圈上；
所述刀具容置腔4的外壁上开设有用于连接定刀2的固定孔，所述定刀2上开设有与所述固定孔一一对应的安装孔21，使得定刀2可拆卸的连接所述固定孔；
所述定刀2的刀刃与转动轴31的轴线平行，所述动刀片32的刀刃倾斜于所述定刀2的刀刃。相对倾斜的刀刃切割时形成剪刀形状，更利于薄膜的切割。转动轴31通过电机驱动转动。
如图3所示，若干所述动刀片32的刀刃交替方向相反地倾斜于所述定刀2的刀刃。解决一个方向的刀刃切割留下斜口的问题。
若干所述动刀片32的刀刃与定刀2的刀刃夹角为3-15°。角度根据需要设置，角度过大切割过程将会产生过大的斜口，造成原料浪费，角度过小，剪切不明显，不易切割。
所述刀具容置腔4开孔对面敞口设置，并在敞口上连接废料导筒5。所述废料导筒5的末端连接吸气装置，在切割过程中，吸气装置启动，将切割下来的废料吸出齿形刀，以保持齿形刀的正常工作。所述废料导筒5的外端头（即远离刀架的一端）相对刀架倾斜向下，吸到导筒内的废料不易重新回到刀具中，使得废料不易飞卷飘散在刀具中。
定刀2和动刀3的形状根据需要确定，可以是平直的，也可以是其他形状的，定刀2、动刀3两者适配就行。
所述安装孔21为长条形。使得定刀2相对动刀3的位置可调，这样就可以保证定刀2和动刀3间的间距足够小，可切割0.01mm以下的薄膜。
所述刀架底部固定连接有用于连接机架的安装座6。
