Description

Shuttleless loom separate transmission formula four is through the leno selvage device

The utility model relates to the selvage device on a kind of shuttleless loom.

Because the fabric both sides that shuttleless loom wove are burr, in order to prevent the fabric off-clip, all have leon-selvedge mechanism on the shuttleless loom and twist the limit.The quality of leon-selvedge mechanism performance will directly have influence on the fastness of selvedge (strand limit) and the performance of loom, and then have influence on the quality of fabric and housekeeping thereafter.The leon-selvedge mechanism of producing at present and using mainly contains four leon-selvedge mechanisms of using that German Kl  cker company produces on leno leno edge machine and JW780 type flexible rapier loom.For German Kl  cker company produce four through the leno leno edge machine, though the limit that its strand weaves is more firm, but this four of Kl  cker company must take two pages of heald frames through the leno leno edge machine, because the action of selvedge device can only be moved one on the other, therefore the heald frame utilization rate of loom is subjected to certain restriction, concerning the JW780 type is scratched the leon-selvedge mechanism of type Rapier looms, though its action is driven by transmission mechanism independently, do not take heald frame, but this mechanism during through the Gauze limit, is by preceding finger bar in the system of knitting three, after refer to the swing of bar and perpendicular pin on, following motion is finished.Since refer to before passing bar and after refer to that the upper and lower distance between two warps of bar is too little, distance is also smaller in addition, and therefore sticking yarn phenomenon takes place in actual weaving often, and broken yarn is more, be difficult to weave firm three through the Gauze limit, so just seriously influenced the normal operation of loom.Therefore, this machine is only knitted in the reality start and is made two through the Gauze limit.Two through the Gauze limit to some fabric, its selvedge fastness is relatively poor, and the off-clip phenomenon takes place often, has a strong impact on the quality of fabric, so its scope of application is restricted equally.

The purpose of this utility model is in order to overcome above-mentioned deficiency, and a kind of independently transmission mechanism that has of design, and can knit and make the four firm leon-selvedge mechanisms through the Gauze limit.

The utility model is to realize like this, it is that a pair of guide rod that is parallel to each other is installed on lateral frame and the middle lateral frame by raising bed rearrangement and middle adjustment seat, its leon-selvedge mechanism adopts four through the leno leno edge machine, this leno edge machine is fixedly mounted in the middle of the right guide rod by the guide rail plate, also be mounted between two guide rail plates, the feeder seat of leno edge machine is fixedlyed connected with left guide rod through a pull bar.In middle adjustment seat bottom-hinged a rib-loop fork is arranged, be hinged with a left connecting rod between the left end of rib-loop fork and the left guide rod, a hinged right connecting rod between its right-hand member and the right guide rod.A wherein end of rib-loop fork is hinged through trace and following lateral frame, forms on the slide bar that following lateral frame is fixed on actuating unit is connected.Said actuating unit is the device that the power that moves up and down is provided for slide bar.This actuating unit can be made up of toggle, also can be made up of cam mechanism etc.The operation principle of this leon-selvedge mechanism is: when slide bar moved downward by following lateral frame drive trace, the rib-loop fork then clockwise rotated, and the rib-loop fork drives right guide rod through right connecting rod and moves downward, and drives left guide rod through left connecting rod and moves upward.The moving downward of right guide rod drives the perpendicular pin that is fixed on above it and moves downward, and the moving upward of left guide rod drives feeder seat through pull bar and move upward, and feeder seat then promotes the magnetic conductance sheet and moves upward.When slide bar moves upward, then drive trace through following lateral frame and move upward, trace then promotes the rib-loop fork and rotates counterclockwise, the rotating counterclockwise of rib-loop fork, then by left and right guide rod drive feeder seat respectively, the magnetic conductance sheet moves downward, perpendicular pin moves upward.Perpendicular pin in this leno edge machine move up and down and feeder seat, magnetic conductance sheet following gone up motion and then made this four knit through the leno leno edge machine and to make firm four through the Gauze limit.

Because selvedge that this leon-selvedge mechanism twisted out is four through the Gauze limit, its strand selvedge is the same through the leno tissue with three, organizes much firm through leno than two.Its scope of application is also organized wide through leno than two, selvedge firmly is difficult for slippage, even if under the stressed bigger situation of when arrangement back selvedge, also be difficult for making cloth impaired, because this leon-selvedge mechanism is not to drive its work by heald frame, but has independently actuating unit, it does not influence the utilization rate of combining cabinet, its strand limit time is not subjected to the restriction of heald frame yet, can adjust arbitrarily.Because the front and back size of this leon-selvedge mechanism is little, make first page of heald frame can be designed into seldom limit to the distance of reed.
