High reliability broken needle detection device

Abstract

The invention provides a high-reliability needle breakage detection device. The high-reliability needle breakage detection device has the characteristics that a needle breakage phenomenon can be detected without needling axial movement, automatic exit can be realized when detection is not needed, the sensitivity is higher, the limited working area of a hosiery machine is not excessively occupied, yarns are not easily enwound, the problems such as yarn breakage are avoided, the design, installation and debugging are simpler, and the stability and reliability are higher. The high-reliability needle breakage detection device comprises an installation seat fixedly connected with the hosiery machine, wherein the installation seat is slidably connected with a slider, the slider is driven by a driving device to slide, a detection element is further arranged on the slider, the detection element comprises a conducting tube and a conducting rod with one end inserted into the conducting tube and the other end suspended outside the conducting tube, the conducting rod is provided with a first conducting part which can contact with the conducting tube to realize conduction when the conducting rod swings, the conducting tube and the slider are mutually insulated, and the conducting tube and the first conducting part are respectively and electrically connected with a hosiery machine controller.

Description

technical field [0001] The invention relates to the technical field of socks production and manufacturing equipment, in particular to a high-reliability broken needle detection device. Background technique [0002] The sock knitting machine is one of the important equipment for producing socks. The quality of the sock knitting machine directly affects the quality of socks. During the production process of existing production equipment, it is inevitable that the sock knitting needles will be broken due to human or external reasons. The broken hosiery needle just can't hook thread, can't carry out knitting normally, thus occurs product weaving, influences product quality, increases production cost. [0003] At present, most of the detection probes of existing detection devices extend vertically downward from the upper end of the hosiery machine working area to the upper end of the sock needle. When a needle breaks, there will be a phenomenon of thread stacking, and the thread ...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to overcome the defects in the prior art and provide a high-reliability broken needle detection device. This invention can detect broken needles without axial movement and can It automatically exits when the time is off, the sensitivity is high, and it does not need to occupy too much limited working area of ​​the hosiery machine, and it is not easy to be entangled with the thread, causing problems such as disconnection. At the same time, the design, installation, and debugging are relatively simple, and the stability and reliability are high.
