The invention relates to the field of weaving machines, in particular to a detection device of a knitting needle element, a knitting machine and a detection method of the knitting needle element. The detection device of the knitting needle element comprises an electromagnetic induction measurement unit and coils used for generating an alternating magnetic field and receiving an induced magnetic field fed back by the knitting needle element, wherein the electromagnetic induction measurement unit comprises an input end and an output end, the input end is in electric connection with the coils, and the output end outputs electromagnetic induction measurement data obtained according to the alternating magnetic field and the induced magnetic field. The detection device of the knitting needle element and the detection method of the knitting needle element are free of influences of cotton fiber, dust and the like on the knitting needle element and accordingly the misjudgment that the knitting needle element lacks cannot occur.
Description
technical field [0001] The invention relates to the field of textile machinery, in particular to a detection device for knitting needles, a loom and a detection method for knitting needles. Background technique [0002] The knitting needles inside the traditional hosiery machine, because of the internal structure, are difficult to find when the knitting needles are missing. If the knitting needles are missing and are not replaced in time, then inferior products will be knitted. [0003] In the related technology, the detection device of knitting needles uses the principle of laser reflection to detect whether the knitting needles are broken. When the laser is emitted, if the metal knitting needles exist, they will be reflected. Whether the knitting needle is missing. [0004] However, in the application of the detection device for knitting needles in the related art, the inventor found the following disadvantages: the laser light may be absorbed by the cotton wool and dust ...
