Description

一种新型瓦楞纸施胶辊组
技术领域
本实用新型涉及造纸机械,特别是一种造纸机上的瓦楞纸施胶辊组。
背景技术
传统的的瓦楞纸施胶辊组两根辊均是圆柱形,由于瓦楞纸施胶辊组体积、质量大,轴向长度长,由于自重而产生弯曲形变,造成瓦楞纸施胶的时候受力不均,容易产生断纸,不但造成了纸张的浪费,还会导致整条造纸流水线停机,严重影响生产。
实用新型内容
为了克服现有技术中存在的上述不足之处,本实用新型的目的在于提供一种新型瓦楞纸施胶辊组,以提高机器的使用寿命。
为了达到上述之目的,本实用新型采用如下具体技术方案:
一种新型瓦楞纸施胶辊组,包括上辊和下辊,所述上辊包括同轴固连的上辊部和上辊轴,所述下辊包括同轴固连的下辊部和下辊轴,其特征在于:所述下辊部包括两侧对称的圆柱段和中间对称的凸起段,所述凸起段表面沿下辊轴轴向截面为以圆弧,所述凸起段半径最大处比圆柱段大0.3mm~0.5mm所述凸起段长度占下辊部总长的1/3以上。
进一步的,所述凸起段半径最大处比圆柱段大0.4mm。
进一步的,所述凸起段长度占下辊部总长的1/2。
本实用新型与现有技术相比的优点是:下辊部包括两侧对称的圆柱段和中间对称的凸起段,凸起段抵消了辊部变形产生的瓦楞纸过纸受力不均而断裂的情况,提高了造纸设备的稳定性和生产效率。
附图说明
图1是本实用新型的示意图;
下面结合附图对本实用新型作进一步的详细说明。
具体实施方式
为了进一步解释本实用新型的技术方案,下面通过具体实施例来对本实用新型进行详细阐述。
实施例1:
如图1所示,一种新型瓦楞纸施胶辊组,包括上辊和下辊,其中,上辊包括同轴固连的上辊部1和上辊轴2,下辊包括同轴固连的下辊部3和下辊轴4,下辊部3包括两侧对称的圆柱段32和中间对称的凸起段31,凸起段31表面沿下辊轴4轴向截面为以圆弧,凸起段31半径最大处比圆柱段32大0.3mm~0.5mm,优选凸起段31半径最大处比圆柱段32大0.4mm。所述凸起段31长度占下辊部3总长的1/3以上,优选凸起段31长度占下辊部3总长的1/2。
以上所记载,仅为利用本创作技术内容的实施例,任何熟悉本项技艺者运用本创作所做的修饰、变化,皆属本创作主张的专利范围,而不限于实施例所揭示者。
