A disconnection detection device

Abstract

The invention discloses a broken yarndetection device. The device comprises a surface cover and a detection box, the detection box is internally provided with a rectangular mounting base plate, mounting holes are formed in the four corners of the mounting base plate, the center of the rear end surface of the mounting base plate is fixedly provided with a contact sensor, a probe of the contact sensor is exposed out of the front end surface of the mounting base plate, the portions, at the upper and lower sides of the contact sensor, of the front end surface of the mounting base plateare providedwith an upper tensioning rod and a lower tensioning rod in a staggered mode, one end of the upper tensioning rod is hinged close to the side edge of one side of the mounting base plate, the other endof the upper tensioning rod is hinged to an upper tensioning wheel through a bearing and a support column, one end of the lower tensioning rod is hinged close to the side edge of the other side of the mounting base plate, and the other end of the lower tensioning rod is hinged to a lower tensioning wheel through a bearing and a support column; the upper side edge of the lower tensioning rod and the lower side edge of the upper tensioning rod are fixedly provided with an upper magnet strip and a lower magnet strip which are attracted to each other respectively. The broken yarndetection devicecan keep yarn tensioned and quickly judge conditions at the same time so that equipment can stop automatically.

Description

Technical field: [0001] The present invention relates to the technical field of detection devices, and more specifically relates to a disconnection detection device. Background technique: [0002] At present, the mechanical broken end stop needle (self stop lever) is widely used as a thread breakage detection device in doubling, twisting, and two-for-one twisting. On the yarn), when the yarn is broken, the self-stop needle (self-stop lever) falls down due to its own gravity, and after falling, it touches a mechanism, which prompts the bobbin bracket to lift up, and the bobbin is not raised properly. The tank will not rotate when it touches, thus playing a self-stop function. But the existing machine parts matching with the dead end self-stop needle (self-stop bar) often break down, and when the dead end self-stop needle (self-stop bar) fell, the machine parts failed to lift the spool. There is also a problem in using the dead end self-stop needle (self-stop bar) simultaneo...

Problems solved by technology

However, the current mechanism that matches the dead end self-stop needle (self-stop lever) often breaks down. When the dead end self-stop needle (self-stop lever) falls, the mechanism fails to lift the bobbin

At the same time, there is still a problem with the use of the dead end self-stop needle (self-stop lever). When the broken end self-stop needle (self-stop lever) falls and the bobbin is lifted, the bobbin will continue to rotate due to inertia after it is lifted.
