【技术实现步骤摘要】
一种薄膜切边齿形刀
本专利技术涉及一种切割刀具,具体涉及一种薄膜切边齿形刀。
技术介绍
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。
技术实现思路
本专利技术针对以上问题,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。本专利技术的技术方案是: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。本专利技术的有益效果是: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 ...
