Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in detail.
The tension-detecting mechanism exporting warp place in warp beam comprises jockey pulley 3, tension pick-up 6, warp beam 5, tension force Rocker arm 4, tension pick-up 4 is arranged on below warp thread 2, near tension force Rocker arm 4, tension force Rocker arm 4 be connected, the two ends of tension force Rocker arm 4 are connected with jockey pulley 3, spring 7 respectively.Additional rollers 1 is arranged between warp beam and jockey pulley, make additional rollers, between warp beam and jockey pulley three, form a leg-of-mutton line, make to act on be less than making a concerted effort in additional rollers warp from warp beam out act directly on afterwards jockey pulley make a concerted effort, concrete additional rollers 1 is positioned at the oblique upper of warp beam, the oblique below of jockey pulley 3, warp is pile warp additional rollers after jockey pulley, enters jockey pulley from additional rollers.The active force that warp passes to jockey pulley is passed to spring by tension force rocking arm, and tension force passes at tension pick-up by spring again, on tension pick-up, finally detect that warp acts on making a concerted effort on jockey pulley.
Method of work of the present invention realizes like this, through additional rollers after warp 2 lays out from warp beam, jockey pulley is entered afterwards from additional rollers, last warp from jockey pulley out through tension pick-up, the active force that warp passes to jockey pulley is passed to spring by tension force rocking arm, on tension pick-up, making a concerted effort on jockey pulley finally detected.
Parcel angle before the parcel angle that the object of additional rollers 1 produces after being to make warp 2 be wrapped in jockey pulley is greater than.When not arranging additional rollers, the wrap angle between warp is β, and the wrap angle after arranging additional rollers between line is that a, a are greater than β.
Fig. 2 acts on the schematic diagram of making a concerted effort on jockey pulley when being and not arranging additional rollers.Fig. 3 acts on the schematic diagram of making a concerted effort on jockey pulley when being and arranging additional rollers.F1 is greater than F2 with joint efforts with joint efforts.
Parallelogram law is followed in the synthesis of power, and in this parallelogram, the diagonal folded by two adjacent sides is made a concerted effort exactly, and the action direction of making a concerted effort is towards jockey pulley position, and that is force action is on jockey pulley.Wrap angle determines the size of making a concerted effort that warp is formed after jockey pulley both sides pull, and object of the present invention is exactly reduction warp making a concerted effort on jockey pulley, and briefly, wrap angle is greatly then little with joint efforts, and wrap angle is little then makes a concerted effort greatly.Make a concerted effort to come from the tension force of warp in two area segments, therefore can well reflect the situation of tension force with joint efforts.The either large or small situation can feeding back tension force with joint efforts, technology before not having to improve, impact is had on jockey pulley when making a concerted effort large, slight tension variation cannot obtain accurate feedback rapidly from jockey pulley, and the present invention is making a concerted effort hour to be fed back clearly on jockey pulley, make a concerted effort like this action effect on jockey pulley is accurate fast, this also make detection sensitivity of the present invention and accuracy high.Little with joint efforts, jockey pulley can also be made to adopt light structures to make, because large words of making a concerted effort just need jockey pulley to have stronger supporting construction, otherwise, can adopt the structure of lightweight, after the structure light wt of jockey pulley, it promotes further to the susceptibility of making a concerted effort, and the sensitivity so detected is just higher.And warp quantity of the prior art is limited, making a concerted effort that such as prior art middle longitude produces is 10 Ns, so ten warps just produce 100 Ns, warp is many, the cloth width manufacturing gained is just large, during multiple spot warp, jockey pulley will bear more making a concerted effort so again, until jockey pulley cannot obtain the ability detecting tension force.Therefore, be limited to above-mentioned reason in prior art, the woven cloth wide cut of institute is little.And little with joint efforts in the present invention, can arrange more warps on jockey pulley, thus can weave wider cloth, what reason was that a warp produces on jockey pulley makes a concerted effort to be far smaller than making a concerted effort in prior art.
Increase additional rollers, additional rod also assume responsibility for the component on a part of pile warp jockey pulley simultaneously.Component is little, and nature of making a concerted effort is also little.
These are only the preferred embodiment of the embodiment of the present invention; not in order to limit the embodiment of the present invention; within all spirit in the embodiment of the present invention and principle, any amendment done, equivalent replacement, improvement etc., all should be included in the protection domain of the embodiment of the present invention.
