[发明专利]一种织机折入边装置的凸轮

说明书

技术领域

本发明属于织机零部件领域，尤其与一种织机折入边装置的凸轮有关。

背景技术

折入边装置能使织机织成的织物具有光边性能和风格，织物为光边时能增加边部强度和保持布幅，具有方便挂浆、洗涤、减少裁剪撬边等功能。目前市场上的共轭凸轮机械式折入边装置采用的动力传动连接方式分上置式同步带传动和下置式齿轮传动两种，上置式同步带传动既存在不安全性，又遮挡操作工视线，多个装置距离较近时难以容纳。下置式齿轮传动虽然比较安全，但最多只能容纳两个中间折入边装置，如再需增加中间折入边装置，需再借用一套同步带传动机构进行组合使用，装置组成的零部件多，体积庞大，安装空间位置占用大，都不适应毛巾、围巾等窄幅、多幅织物的织造。并且共轭凸轮制造精度要求又很高，制造加工困难，导致生产成本较高，当在同一台织机安装多个折入边装置的情况，价格更难以让用户接受，导致市场难以普及。

为解决上述问题，本专利申请人开发了一种柔性折入边装置，含有一套驱动机构，多套执行单元及相互连接构件，驱动机构主要由一套（共5个）驱动凸轮和相对应的摆动臂组成，所以需要开发用于驱动装置的驱动凸轮。 

发明内容

本发明目的旨在适应一种柔性折入边装置的驱动机构需要，提供一种结构相对简单、成本较低并能使织机折入边装置平稳运行的织机凸轮。

为此，本发明采用以下技术方案：一种织机折入边装置的凸轮，凸轮体上设置有轴孔，凸轮体为两个端面和一个曲面连接组成的盘形结构，曲面母线与轴孔中心线平行，曲面轮廓线为具有变化向径的曲线，其特征是：所述凸轮体曲面轮廓线由360个点依次光滑连线组成，该360个点的位置由极坐标系确定，每一点的极坐标系的极角和极径如下表所示，
