Abstract

一种碎纸机刀片，它是采用圆形刀体外圆上设置的齿形刀锋与圆形刀体为一体结构，齿形刀锋为圆形刀体基材90°弯曲后形成的齿形刀锋的前刀面结构，齿形刀锋的前刀面宽度，大于刀体基材的厚度。圆形刀体90°弯曲的基材，一部分构成齿形刀锋的前刀面，一部分在刀体与齿形刀锋前刀面连接的外边圆上，构成连续弧形排屑面。它主要解决减少刀片材料消耗的技术问题，本实用新型的有益效果是，该刀片具有结构简单，加工容易，刀片耗材少，使用时纸屑排除通畅，降低产品制造成本，同时减轻碎纸机的整体重量。

Description

一种碎纸机刀片
所属技术领域
本实用新型涉及一种办公用碎纸机刀片，特别是一种可减少刀片材料消耗的碎纸机刀片结构。
背景技术
目前，公知技术中，办公用碎纸机上使用的碎纸刀片是碎纸机经常更换的易损零件，在碎纸机上使用时，有左右对称两个刀片组成一组，多组刀片同时安装在驱动轴上，每组刀片之间要有一定的设计距离(既碎纸宽度)，左右对称两个刀片背靠被对应安装，两个刀片的圆形刀体和齿形刀锋接触，现有技术为满足上述设计要求，一种是采用将刀体和齿形刀锋使用同一基材冲出，刀体和齿形刀锋同为基材厚度，使用该结构刀片耗材量大，增加制造成本，另一种是采用将刀体设计成曲面形状或局部加厚齿形刀锋部分，以达到降低刀片耗材，该结构刀片形状复杂，加工工艺复杂。
发明内容
为克服现有技术中刀片耗材量大，增加制造成本和异型刀片形状复杂，加工的技术不足，本实用新型设计一种碎纸机刀片，该刀片具有结构简单，加工工艺简单，刀片耗材少，纸屑排除通畅。
本实用新型解决其技术问题所采用的技术方案是：一种碎纸机刀片，由圆形刀体，在圆形刀体的圆心设置有驱动轴安装孔，圆形刀体外圆上设置有齿形刀锋构成，圆形刀体外圆上设置的齿形刀锋与圆形刀体为一体结构，齿形刀锋为圆形刀体基材90°弯曲后形成的齿形刀锋的前刀面结构，齿形刀锋的前刀面宽度，大于刀体基材的厚度。圆形刀体90°弯曲的基材，一部分构成齿形刀锋的前刀面，一部分在刀体与齿形刀锋前刀面连接的外边圆上，构成连续弧形排屑面。圆形刀体上设置有环形凸起，带环形凸起的圆形刀体厚度与齿形刀锋的前刀面宽度相同。
本实用新型的有益效果是，该刀片具有结构简单，加工容易，刀片耗材少，纸屑排除通畅，降低产品制造成本和整机重量。
附图说明
下面结合附图和实施例对本实用新型进行描述。
图1为本实用新型示意图。
图2为图1A向示意图。
图3为左右对称两个刀片安装使用示意图。
图中，1圆形刀体、2齿形刀锋、3环形凸起。
具体实施方式
参看附图，圆形刀体1外圆上设置的齿形刀锋2与圆形刀体1为一体结构，为保证齿形刀锋2有一定厚度，即齿形刀锋2的前刀面宽度，齿形刀锋2采用圆形刀体1基材90°弯曲后形成的齿形刀锋2的前刀面结构，齿形刀锋2的前刀面宽度，大于刀体1基材的厚度。
为使齿形刀锋2增加刚性和刀体1与齿形刀锋2前刀面连接的外边圆形成连续的排屑面，使纸屑排除通畅，圆形刀体190°弯曲的基材，一部分构成齿形刀锋2的前刀面，一部分在刀体1与齿形刀锋2前刀面连接的外边圆上，构成连续弧形排屑面。
为使刀体1增加刚性及左右对称两个刀片在安装使用时，两个刀片的刀体1和齿形刀锋2接触，防止夹纸，圆形刀体1上设置有环形凸起3，带环形凸起3的圆形刀体1厚度与齿形刀锋2的厚度尺寸应保证相同。即与齿形刀锋2的前刀面宽度相同。
圆形刀体外圆上设置的齿形刀锋2根据碎纸要求，可在圆形刀体外圆上对应或均部设置2-6各个。
本实用新型实施例采用上述结构，降低刀片材料消耗，减少碎纸机的使用和制造成本，刀片加工工艺简单，使用时纸屑排除通畅，同时减轻碎纸机的整体重量。
