Description
技术领域
本发明涉及一次性卫生用品领域,尤其涉及一种曲线橡筋施加装置。
背景技术
在一次性卫生用品领域中,纸尿裤施加弹性橡筋已经是一种公知技术,而且现有的弹性橡筋往往都是连续性附加的,即是将弹性橡筋附加于表层材料与底层材料之间后,然后经过裁剪形成单个的纸尿裤半成品。现有的弹性橡筋的施加往往都是直线式的,少部分是通过曲线的方式施加,然而现有的曲线橡筋的施加装置往往较为复杂,稳定性较差。
发明内容
本发明要解决的技术问题是提供一种结构简单、稳定性好、施加方便的曲线橡筋施加装置。
为达到上述目的,本发明的技术方案是:一种曲线橡筋施加装置,包括机架、可转动地设于机架上的上复合轮、可转动地设于机架上的下复合轮、可转动地设于机架上的两个橡筋释放轮,所述上复合轮与下复合轮相互靠近以实现夹持输送,两橡筋释放轮与上复合轮之间分别设有复合伺服电机,各复合伺服电机的转轴上设有摆臂,所述摆臂的自由端上设有橡筋导引机构。
优选的,所述橡筋释放轮与复合伺服电机之间设有用于调节橡筋张紧度的张紧调节装置,所述张紧调节装置包括沿橡筋输送方向间隔设置的第一夹持输送机构与第二夹持输送机构。
优选的,所述第一夹持输送机构与第二夹持输送机构均包括可转动地设于机架上的主动轮、可转动地设于机架上的被动轮、驱动主动轮的夹持伺服电机,所述主动轮与被动轮相互靠近以实现对橡筋的夹持输送。
优选的,所述橡筋导引机构为一圆环。
优选的,两摆臂上下错位设置。
优选的,所述机架上位于上复合轮的一侧设有喷胶装置。
上述技术方案具有如下有益效果:本曲线橡筋施加装置通过设置复合伺服电机、摆臂来实现橡筋的曲线调整,从而可以形成任意设定的曲线样式,且结构简单、工作状态稳定、维修方便;进一步的,通过第一夹持输送机构、第二夹持输送机构的配合,可以用于调节弹性橡筋的张紧度,而且可以令第一夹持输送机构的线速度与橡筋释放轮的线速度相同,而利用第二夹持输送机构与第一夹持输送机构的转动速度差来实现橡筋的张紧度的控制;进一步的,通过两摆臂上下错位设置,可以实现两摆臂的交错,从而可以实现两曲线橡筋段的交错。
附图说明
图1是本发明实施例的结构示意图;
图2是图1俯视状态的结构示意图;
图3是摆臂交错后形成的橡筋曲线分布的状态图;
图4是利用曲线橡筋施加装置形成的纸尿裤。
具体实施方式
下面结合附图和具体的实施方式对本发明作进一步详细说明。
图1、图2所示,一种曲线橡筋施加装置,包括机架、可转动地设于机架上的上复合轮1、可转动地设于机架上的下复合轮2、可转动地设于机架上的两个橡筋释放轮3,所述机架上位于上复合轮的一侧设有喷胶装置4。所述上复合轮1与下复合轮2相互靠近以实现夹持输送,两橡筋释放轮3与上复合轮1之间分别设有复合伺服电机5,各复合伺服电机5的转轴上设有摆臂6,两摆臂6上下错位设置。所述摆臂6的自由端上设有橡筋导引机构,所述橡筋导引机构为一圆环7。所述橡筋释放轮3与复合伺服电机5之间设有用于调节橡筋张紧度的张紧调节装置,所述张紧调节装置包括沿橡筋输送方向间隔设置的第一夹持输送机构8与第二夹持输送机构9。所述第一夹持输送机构8与第二夹持输送机构9均包括可转动地设于机架上的主动轮81、可转动地设于机架上的被动轮82、驱动主动轮的夹持伺服电机,所述主动轮81与被动轮82相互靠近以实现对橡筋的夹持输送。
再参考图3,为摆臂交错后形成的橡筋曲线分布的状态图,其中A为橡筋。
再参考图4,为利用本曲线橡筋施加装置形成的纸尿裤,其中B为橡筋。
本曲线橡筋施加装置的工作方式为:上复合轮与下复合轮夹持输送,且表层材料绕经上复合轮,底层材料绕经下复合轮,喷胶装置对着表层材料喷胶。同时,橡筋由橡筋释放轮释放,经过第一夹持输送机构、第二夹持输送机构后穿过圆环,复合于表层材料与底层材料之间。将需要曲线的参数提供给电气控制系统,通过电气控制系统控制复合伺服电机来实现摆臂的摆动,从而形成所需要的曲线样式。而且在曲线橡筋的复合过程中,可以调节第一夹持输送机构、第二夹持输送机构的速度差,来实现对弹性橡筋的张紧度的调整。
通过橡筋释放轮、第一夹持输送机构、第二夹持输送机构、上复合轮的各个转动速度的调整,即橡筋释放轮与第一夹持输送机构的速度相匹配,第二夹持输送机构、上复合轮的速度相匹配,而通过第一夹持输送机构与第二夹持输送机构的速度差值来实现张紧度的精确控制。
本曲线橡筋施加装置通过设置复合伺服电机、摆臂来实现橡筋的曲线调整,从而可以形成任意设定的曲线样式,且结构简单、工作状态稳定、维修方便;进一步的,通过第一夹持输送机构、第二夹持输送机构的配合,可以用于调节弹性橡筋的张紧度,而且可以令第一夹持输送机构的线速度与橡筋释放轮的线速度相同,而利用第二夹持输送机构与第一夹持输送机构的转动速度差来实现橡筋的张紧度的控制;进一步的,通过两摆臂上下错位设置,可以实现两摆臂的交错,从而可以实现两曲线橡筋段的交错。
以上仅是本发明一个较佳的实施例,本领域的技术人员按权利要求作等同的改变都落入本案的保护范围。
