Description

Online detection device for working state of ring spinning frame

Technical Field

The utility model relates to a ring spinning frame detection device especially relates to a ring spinning frame operating condition on-line measuring device, belongs to weaving equipment technical field.

Background

In the process of a ring spinning frame, after roving is unwound from a roving bobbin on a spindle, the roving is fed into a drafting device, the drafted yarn is output by a front roller, supported by a yarn guide hook, passes through a steel wire ring and is wound on a bobbin tightly sleeved on the spindle, the bobbin rotating at high speed drives the steel wire ring to rotate on a steel collar by virtue of the yarn, and one twist is added to the yarn when the steel wire ring rotates one turn; the rotating speed of the steel wire ring is lower than that of the bobbin, and the yarn output by the front roller is regularly wound on the bobbin according to a certain forming requirement by means of the lifting motion of the ring rail.

In the spinning process of the ring spinning frame, yarns need to pass through components such as a yarn guide hook and the like, the yarn guide hook is arranged on a lappet, and the lappet is arranged on a long beam of a rack. The yarn guide hook is a supporting point in the spinning process of a spinning frame, the spinning tension acts on the yarn guide hook, the yarn and the yarn guide hook are in contact friction, the yarn guide hook can do reciprocating motion from a balance position of the yarn guide hook in the continuous descending motion process of the yarn, the yarn guide hook is forced to vibrate, and an excitation source of the forced vibration is the moving yarn.

An existing online detection device for the working state of a ring spinning frame, for example, a structure disclosed in the chinese patent invention, patent No. 201310232141.1, entitled "monitoring method and judgment method for the working state of a ring spinning frame", has an induction device disposed in a sensing region of an air ring of the spinning frame, the induction device induces a digital signal generated by the rotation of the air ring of the spun yarn, and analyzes the output digital signal to judge the working state of the ring spinning frame; the sensing device is a photoelectric detection device, the photoelectric detection device consisting of a light emitting tube and a photoelectric receiver is arranged on the yarn guide hook, and a probe of the photoelectric receiving device and the light emitting tube corresponding to each yarn guide coil is arranged on an air ring yarn path of the spinning machine. The working state online detection device of the ring spinning frame with the structure has the following two defects in the working process: on one hand, the induction device is arranged in the sensing area of the spinning frame balloon, the induction device induces the digital signal generated by the rotation of the spinning frame balloon, the output digital signal is analyzed only in the time domain, the working states of the 11 spinning frames in the patent cannot be completely and accurately reflected, and some detection and analysis results are inaccurate and have poor reliability; on the other hand, as the spectrum line of the light-emitting tube increases along with the increase of the lighting time, the main peak starts to move towards the long wave direction after being lighted for 100-150 h, the main peak is excited to gradually descend, meanwhile, the luminous flux also gradually descends, and the photoelectric receiver of the light-emitting tube cannot be accurately converted into a distance signal between the balloon of the yarn and the detection element through the inherent circuit processing; moreover, joule heat generated when the light emitting tube works, heat generated by a PN junction and heat generated after light is absorbed can greatly influence the magnitude of an analog signal output by a signal capturing or sensing device in the scheme after filtering and amplifying a digital signal, and influence the judgment of a singlechip of the signal capturing or sensing device; in addition, fibers floating in the photoelectric detection area of the spinning frame can cover the photoelectric device, and the detection accuracy can be reduced.
