Roller device for detecting tension of fiber tow in front of crimping machine

The utility model particularly discloses a roller device for detecting the tension of a fiber tow in front of a crimping machine. The roller device comprises a roller rotating shaft; the roller cylinder body is coaxially and rotatably connected with the roller rotating shaft through a bearing; the tension detection mechanism comprises a pressure sensor fixed on the roller rotating shaft, the pressure sensor is connected with a contact part, and the contact part is in rolling contact with the upper side of the inner wall of the roller cylinder. According to the device, tension sensors do not need to be installed at the two ends of the roller rotating shaft respectively, installation and debugging time is saved, and cost can be reduced. 本实用新型专利具体公开了一种用于卷曲机前纤维丝束张力检测的罗拉装置，包括：罗拉转轴；罗拉筒体，罗拉筒体通过轴承和罗拉转轴同轴转动连接；张力检测机构，其包括固定于罗拉转轴上的压力传感器，压力传感器连接有接触部，接触部和罗拉筒体的内壁的上侧滚动接触。本装置无需对罗拉转轴的两端分别安装张力传感器，节省安装和调试时间，且能够降低成本。
