Description

一种用于回收废弃泡沫塑料的冷压机的泡沫塑料粉碎刀
技术领域
本发明涉及一种用于回收废弃泡沫塑料的冷压机，尤其涉及位于冷压机的粉碎箱中对泡沫塑料进行粉碎的粉碎刀。
背景技术
目前在许多产品生产销售流通过程中，需在产品包装箱内垫衬大量的泡沫塑料以缓冲外力对包装箱的冲击力。由于泡沫塑料对环境的危害很大，因此需要对其进行回收。常用的用于回收废弃泡沫塑料的冷压机都设置有粉碎箱，在粉碎箱中设粉碎刀，粉碎刀由电机带动旋转。常用的粉碎刀的结构是在旋转轴上安装若干个刀片，各刀片间隔且相互错开排列，这种结构适宜粉碎一般的泡沫塑料，但当粉碎硬度较大的泡沫塑料时，会出现粉碎不彻底、粉碎后的泡沫塑料块不均匀的现象，有时还会出现泡沫塑料无法粉碎，刀片被卡滞的现象。
发明内容
本发明的目的是为克服现有技术的不足，提供了一种可粉碎硬度较大的泡沫塑料粉碎刀。
本发明采用的技术方案是：在主轴上安装主动刀，在副轴上安装被动刀，主动刀与被动刀均由若干个刀片组成，主轴与副轴平行布置，在主动刀与被动刀的下方固定定刀，定刀由若干个刀片组成，主动刀与被动刀的旋转方向相反；在主动刀的刀片上垂直固定两片横刀，该两片横刀以主轴对称布置，在被动刀的刀片上垂直固定两片横刀，该两片横刀以副轴对称布置，横刀与横刀背向设置；主动刀上的刀片与定刀上的刀片成角度相互错开，被动刀上的刀片与定刀上的刀片呈角度错开；主动刀与被动刀上的刀片的旋转外径沿轴向依次变小。
本发明可以粉碎硬度较大的泡沫塑料，粉碎后的泡沫塑料块大小均匀，粉碎效果好。
附图说明
下面结合附图和具体实施方式对本发明作进一步说明。
图1为本发明结构主视示意图。
图2为图1的左视图。
图中：1.主动刀；2.被动刀；3.定刀；4.主轴；5.副轴；6.横刀；7.横刀。
具体实施方式
如图1所示，本发明由主动刀1、被动刀2和定刀3组成。主动刀1安装在主轴4上，被动刀2安装在副轴5上，主轴4与副轴5相互平行。主动刀1由若干个刀片组成，被动刀2也由若干个同样的刀片组成，主动刀1与被动刀2的旋转方向相反，主动刀1上的刀片与被动刀2上的刀片均相互错开间隔布置，使主动刀1与被动刀2不发生干涉。主动刀1上的刀片的旋转外径沿主轴4的轴向依次变小，被动刀2上的刀片的旋转外径沿副轴5轴向依次变小，这样，在粉碎过程中大小不同的泡沫塑料块就具有粉碎的间隙，可有效地进行粉碎，且可防止刀片被卡滞。
在主动刀1与被动刀2的正下方固定定刀3，定刀3由若干个刀片组成。在主动刀1的刀片上垂直固定两片横刀6，该两片横刀6以主轴4为中心轴对称布置，在被动刀2的刀片上垂直固定两片横刀7，该两片横刀7以副轴5为中心轴对称布置。横刀6与横刀7的朝向相反，相对于刀片来说为背向设置。
主动刀1上的刀片与定刀3上的刀片成角度相互错开，使主动刀1与定刀3不发生干涉，被动刀2上的刀片与定刀3上的刀片呈角度错开，使被动刀2与定刀3不发生干涉。工作时，主动刀1正向旋转、被动刀2逆向旋转，泡沫塑料被粉碎后只有达到主动刀1与定刀3或者被动刀2与定刀3间的间隙尺寸时才能通过，否则将停留在定刀3上继续被粉碎，由于定刀3不旋转，其强度和刚度都优于常规结构的旋转刀组，可以粉碎硬度较大的泡沫塑料。
