Abstract

本实用新型公开了一种碎纸机刀具结构，包括刀轴、刀具，刀具依次套在刀轴上，刀轴为圆柱形，两侧对称开有通槽，相应的刀具内环上同向对称布置有一方形凸块安装在所述刀轴的通槽内。由于在刀具内环上设计了凸块，就无需传统的刀环，减少了整个刀具结构的组件，装配上较传统结构简单的多，且成本也大为减少；另外，由于去除了刀环，刀具的径向进刀量大大增加，碎纸量相较传统刀具结构可增加5～6张。

Description

碎纸机刀具结构
技术领域
本实用新型涉及切割设备，尤其涉及碎纸机的刀具结构。
背景技术
如图1～图4所示，传统的碎纸机刀具结构是由刀具、刀轴和刀环组装而成，刀具12和刀环13间隔布置在刀轴11上，装配比较复杂、烦琐，另外由于刀环的径向尺寸较大，阻碍了刀具的径向进刀量，使得碎纸机的碎纸数量受到限制。
发明内容
本实用新型的目的就是克服现有技术的上述不足之处，提供一种装配简单、能有效增加碎纸数量且成本降低的碎纸机刀具结构。
一种碎纸机刀具结构，包括刀轴、刀具，刀具依次套在刀轴上，刀轴为圆柱形，两侧对称开有通槽，相应的刀具内环上同向对称布置有一方形凸块安装在所述刀轴的通槽内。
本实用新型的优点在于，由于在刀具内环上设计了凸块，就无需传统的刀环，减少了整个刀具结构的组件，装配上较传统结构简单的多，且成本也大为减少；另外，由于去除了刀环，刀具的径向进刀量大大增加，碎纸量相较传统刀具结构可增加5～6张。
附图说明
图1是传统刀具结构的立体图；
图2是传统刀具结构的示意图；
图3是传统刀具结构的刀具示意图；
图4是传统刀具结构的刀轴示意图；
图5是本实用新型的立体图；
图6是本实用新型的示意图；
图7是本实用新型的刀具的示意图；
图8是本实用新型的刀轴的示意图。
具体实施方式
下面结合附图对本实用新型作进一步详述。
如图5～图8所示，本实用新型碎纸机刀具结构由刀轴21和刀具22组装而成，刀具22依次套在刀轴21上，刀轴21为圆柱形，两侧对称开有通槽211，相应的刀具22内环上同向对称布置有一方形凸块221安装在所述刀轴21的通槽211内。
