The boundary member structure

Technical field

The utility model relates to a kind of boundary member structure, and is particularly a kind of by the preferable contact assembly of a sheathed electric conductivity on stop rod, makes it can significantly increase the boundary member boundary member structure in service life.

Background technology

Along with progressing greatly day by day of industrial and commercial prosperity development and industry science and technology, each industry is fourth of the twelve Earthly Branches foot all one's effort invariably, towards the target hard-working of every automated production, wish to reduce by this labour-intensive degree, save the personnel costs expense, and then reduce production costs, promote product quality and increase its market competitiveness.

The development of knitting machine also is like this, the full-automatic knitting machine of various types, main system relies on tens of even hundreds of yarn feeders are responsible for the knitting required yarn of supply, and the major function of this yarn feeder is exactly to pull out the supply knitting needle again through yarn feeder after yarn is pulled out by the yarn tube in advance to carry out knitting work, use the stable purpose with suitable tension yarn that provides is provided, when yarn feeder causes yarn that fracture or lax situation are arranged because of yarn tension or other factors in the process of work, can come initiatively to detect and send the running that an abnormal signal interrupts whole knitting machine by boundary member, avoid causing problem and loss on dealer's QC because yarn can't regular supply and produce flaw cloth.Therefore this boundary member is a very important assembly on the yarn feeder, be responsible for the work of checking on of whole yarn output, and the kind of yarn feeder is quite a lot of, the relative boundary member that is mated also has multiple different design, see also Figure 1 and Figure 2, for commonly using a kind of boundary member that uses the elastomeric yarn yarn feeder of specializing in, wherein, this boundary member is mainly by housing main body A, stop rod B, holder C, conducting strip D, grounded metal sheet E, control circuit F and elastic adjusting mechanism G constitute, wherein, the holder C system that metal material is made is incorporated into the side of housing main body A, this holder C can be fixed in one and can supply on the guide rail H of power supply, in addition, grounded metal sheet E, conducting strip D, control circuit F and elastic adjusting mechanism G are arranged in the housing main body A, wherein, grounded metal sheet E and holder C are electrically connected, and stop rod B contact grounded metal sheet E also can adjust and bestow the suitably pulling force of size of stop rod B one by elastic adjusting mechanism G, and conducting strip D and control circuit F connect an external power source, the end of conducting strip D is arranged at the position that stop rod B contact can be, by aforesaid structure, this boundary member is fixedly set on the guide rail H that is provided with power supply, and the external power source that is provided on the guide rail is provided for conducting strip D and control circuit F, yarn I pressed down the outer end of stop rod B through the outer end of stop rod B and by the strength of yarn I make stop rod B be positioned at boundary member housing main body A the inner separating with conducting strip D, once the pulling force that the medial extremity of yarn I stop rod B when the situation of fracture takes place can be provided by elastic adjusting mechanism G makes this stop rod B that medial extremity contacts with conducting strip D with the medial extremity of stop rod B is drop-down, this moment, The whole control circuit F promptly can become the state of conducting, and exported the purpose that a signal makes whole knitting machine decommission and reaches timely caution parking.

But; owing to commonly use boundary member is to be electrically connected to utilize stop rod B to contact with grounded metal sheet E earlier as described above; stop rod B by this movable rotation starts boundary member with the mode that conducting strip D contacts conducting again; and stop rod B wherein makes with stainless steel; in addition; this grounded metal sheet E and the conducting strip D overwhelming majority then are to make in the mode of phosphorus bronze sheet nickel plating; because the flowing mode system of doing of this stop rod B touches conducting strip D with moment and produces short circuit phenomenon and make the boundary member start; yet in fact this stainless steel is not to belong to the good material of electric conductivity; therefore in the process of stop rod B and conducting strip D actual contact generation short circuit, inevitably can produce carbon element and spark and corrode this both surface texture; even can be gradually produce the phenomenon of carbon distribution on the two surface that contacts with each other; then can produce the situation that to conduct electricity when soot accumulation to a certain degree the time and can't produce short circuit smoothly and send the signal of parking; description according to on-line operation personnel practical operation personnel; approximately have only 140,000 the normal service life of the aforementioned structure of commonly using; not only normal service life is too short; in case and the dealer is not overhauled replacing in good time; even the yarn of this supply knitting machine generation when its soot accumulation arrives certain degree and when the abnormal situation of confession yarn is arranged; this stop rod B still can't start boundary member smoothly and shut down in good time; and can cause knitting machine to produce substandard flaw cloth, cause the dealer to be returned goods or make more serious losses such as goodwill is impaired.
